Different from traditional filament bulb lamps, the LED filament lamp of the present invention can be used not only as a bulb, but also as a lamp, instead of being required to be installed on a lamp fitting like the traditional bulb lamps.

In addition, the filament structure inside the housing can be designed with magnetic attractive fittings, so that the filament can be fixed to a certain extent while having drooping effect with gravity, which is more ornamental. In addition, due to insufficient weight of the filament, it may be bent after installation, and the filament can be straightened through a magnetic attractive structure.

In order to explain the embodiments of the present disclosure or the technical scheme in the prior art more clearly, the drawings required in the description of the embodiments or the prior art will be briefly introduced below; obviously, the drawings in the following description are only some embodiments of the present disclosure, and other drawings can be obtained according to these drawings by those of ordinary skill in the art without paying creative labor.

The present disclosure will be further described in detail with reference to the following examples which present explanation the present disclosure and the present disclosure is not limited to the following examples.

An LED filament lamp, as shown in <FIG> and <FIG>, includes a power connection assembly <NUM>, a light transmissive housing <NUM> and one or more LED filaments <NUM>. Each of the LED filaments includes a fixed end and a free end, the fixed end is electrically connected with the power connection assembly, the free end of the LED filament is provided with a first connecting member, and the light transmissive housing is provided with a second connecting member matched with the first connecting member. Each first connecting member is matched with one second connecting member in a contact or non-contact manner.

In this embodiment, the free end of the LED filament is provided with a first connecting member, the first connecting member is a first suction member <NUM>; the light transmissive housing is provided with a second connecting member matched with the first connecting member, and the second connecting member is a second suction member <NUM>, and the first suction member is in suction connection with the second suction member.

The first suction member and the second suction member can be magnetic elements. In the following, taking magnetic adsorption as an example, it will be described with reference to <FIG>.

In an implementation, the first suction member is a magnet member or a ferromagnetic suction member, and the second suction member is a ferromagnetic suction member or a magnet member corresponding to the first suction member.

For example, there are three LED filaments. Fixed ends of the three LED filaments are electrically connected with the power connection assembly, and free ends thereof are each fixed with a magnet, which is generally of a small size structure and does not affect overall aesthetics of the LED filaments. An inner surface of the light transmissive housing is respectively provided with three ferromagnetic suction members with their volumes being matched with magnet members. This is preferred for this embodiment and a specific structure and shape are not limited.

On the contrary, the free ends of the LED filaments are each fixed with a ferromagnetic suction member, which is generally of a small structure and does not affect overall aesthetics of the LED filaments.

The inner surface of the light transmissive housing are respectively provided with three magnet members with their volumes being matched with ferromagnetic suction members.

The ferromagnetic suction members generally use metals such as iron, cobalt and nickel, or composite suction members doped with these metals that can adsorb magnets.

As another example, both the first and second suction members are magnets. In this scheme, if the S and N poles of the two magnets are opposite, a magnetic attraction connection can be realized. Because of characteristics of the magnetic connection, a contact or non-contact fixing can be realized. With configuration of the first suction member and the second suction member, the lamp line can be shaped, which not only fixes the lamp line, but also aesthetically molds the lamp line.

This embodiment is different from Embodiment <NUM> in a setting mode of the second suction member. In Embodiment <NUM>, the second suction member can be considered to be provided at a point where several fixed ferromagnetic suction members or magnets are mounted to the inner surface of the light transmissive housing.

In this embodiment, the second suction member can be two suction members installed inside and outside the light transmissive housing respectively, such as one magnet and one ferromagnetic suction member, which are tightly sucked through the light transmissive housing. The external suction member can be moved to drive the internal suction member to move. At this time, a position of the first suction member connected with the inner suction member can be adjusted at will, so as to adjust a position of the lamp line.

This embodiment is different from Embodiment <NUM> and Embodiment <NUM> in provision of the second suction member. In this embodiment, the second suction member includes a magnet or ferromagnetic suction member provided in or shaped on the light transmissive housing.

In production of the light transmissive housing, the suction member is pressed into the inner layer of the light transmissive housing, and the suction member herein can be in a form of a dot, a strip or a sheet. For example, where dot-shaped suction members are used, each of the LED filaments corresponds to one suction member. For example, where sheet-shaped suction members whose areas are larger than those of the point-shaped ones are used, a plurality of first suction members can be absorbed. For example, where strip-shaped suction members are used, the first suction member can be displaced on the strip-shaped suction member to adjust its position. Similar structures can be obtained by analogy.

In other embodiments, the suction member can be attached to the inside or outside of the light transmissive housing.

An LED filament lamp, as shown in <FIG>, includes a power connection assembly <NUM>, a light transmissive housing <NUM> and one or more LED filaments <NUM>. Each of the LED filaments includes a fixed end and a free end, the fixed end is electrically connected with the power connection assembly, the free end of the LED filament is provided with a first connecting member, and the light transmissive housing is provided with a second connecting member matched with the first connecting member.

Not in accordance with the present invention, in this embodiment, the free end of the LED filament is provided with a first connecting member, the first connecting member is a first hooking member; the light transmissive housing is provided with a second connecting member matched with the first connecting member, and the second connecting member is a second hooking member, and the first hooking member is hooked with the second hooking member.

The first hooking member is a hook or a hanging ring fixed to the free end of the LED filament, and the second hooking member is a hook or a hanging ring fixed to the inner wall of the light transmissive housing.

An end of the power connection assembly provided in this embodiment is detachably connected with the light transmissive housing. For example, a lower part of the power connection assembly is provided with a helical structure <NUM>-<NUM>, and correspondingly, the light transmissive housing is provided with a helical structure <NUM>-<NUM> corresponding to the helical structure, and specific positions of an internal thread and an external thread are not limited.

On a basis of the above embodiments, this embodiment can be varied. As shown in <FIG>, its structure further includes a lamp board <NUM> installed at an end of the power connection assembly. A plurality of LED chips or LED lamp beads <NUM>-<NUM> are mounted on the lamp board.

An end of the power connection assembly provided in this embodiment is detachably connected with the light transmissive housing. For example, the lower part of the power connection assembly is provided with a spiral structure <NUM>-<NUM>. In this embodiment, the spiral structure is an inner spiral structure, and the light transmissive housing is an outer spiral structure.

It can be conceivable that the lower part of the power connection assembly can be connected with the light transmissive housing by a buckle or by glue, and other connection structures are not restricted.

In this embodiment, a lamp including at least two LED filaments is disclosed, and free ends of the two LED filaments are connected by a connecting part, the connecting part is a magnet member, a ferromagnetic suction member or is of other non-magnetic materials.

As shown in <FIG>, taking four LED filaments (a structure with two or more other LED filaments is similar) as an example, the connecting part is a cross-shaped or X-shaped bracket <NUM>, and four end points of the bracket are connected to four free ends of the four LED filaments for fixing. The bracket is a magnet member or a ferromagnetic suction member, and the second suction member <NUM> is a ferromagnetic suction member or a magnet member corresponding to the bracket <NUM>. Structural description of this part refers to the above-mentioned embodiments and will not be repeated here.

On the other hand, as shown in <FIG>, when the connecting part is made of other non-magnetic materials, for example, plastic or hard rubber, then a magnet member or a ferromagnetic suction member <NUM>-<NUM> is installed on the connecting part. As such, a design idea of the disclosure can be achieved.

It should be noted that the connecting part of this embodiment is connected with the second suction member in a contact or non-contact manner. The second suction member is adjusted accordingly according to selection of the connecting part in this embodiment.

Not in accordance with the present invention, in another embodiment, the connecting member further includes a hook or a hanging ring, and correspondingly the second connecting member is a hook or a hanging ring corresponding to the connecting member. A specific structure will not be described in detail, which can refer to previous embodiments.

As shown in <FIG>, the second connecting member can be movably installed in the light transmissive housing, which is different from other embodiments and can be applied to other embodiments at the same time. Specifically, it is conceivable to provide a slideway inside or outside the light transmissive housing, and the second connecting member is installed on the slideway.

Alternatively, the second connecting member includes a movable piece and a slideway provided inside the light transmissive housing, and the movable piece is installed on the slideway. The second connecting member can be a second suction member (referring to Embodiment <NUM>).

Generally, the slideway is a concave groove on the inner wall of the housing, and the movable piece includes a slider embedded in the concave groove and a suction member.

In another implementation, more than one slideway is provided on the light transmissive housing, and the second connecting member is clamped on the slideway to realize a sliding connection on the slideway. The slideway disclosed in this embodiment can be integrally formed or assembled separately.

A cross-sectional view of one of forms of a structure of the slideway are respectively disclosed in <FIG> and <FIG>. The light transmissive housing <NUM>, the slideway <NUM> and the first suction member <NUM>-<NUM> are shown in <FIG>, and the light transmissive housing <NUM>, the slideway <NUM> and the second suction member <NUM>-<NUM> are shown in <FIG>. When the light transmissive housing is produced and shaped, more than one slideway protruding into an inner cavity of the light transmissive housing is prepared with a mold, and the slideway includes an inner groove outside the light transmissive housing and a convex groove inside the light transmissive housing. In <FIG>, the first suction member <NUM>-<NUM> is arranged inside the light transmissive housing and clamped on a surface of a convex groove. In <FIG>, the second suction member <NUM>-<NUM> is arranged outside the light transmissive housing and clamped in the groove.

According to <FIG> and <FIG>, another implementation can be conceivable that there is more than one slideway protruding towards outside of the light transmissive housing, and the slideway includes a convex groove outside the light transmissive housing and a groove inside the light transmissive housing. The second suction member can be arranged inside the light transmissive housing and clamped in the groove. The second suction member can also be arranged outside the light transmissive housing and clamped on the convex groove.

As shown in <FIG>, an elongated tubular line lamp is disclosed, in which the light transmissive housing is a long tube, and one or more LED filaments are arranged in the tube. Taking one LED filament as an example, a structure with multiple LED filaments can be obtained according to one LED filament.

Not in accordance with the present invention, in this embodiment, both the fixed end and the free end of the LED filament can be movably connected. As shown in <FIG>, both the free end and the fixed end of the LED filament are provided with a first connecting member, and the first connecting member is a hook <NUM>-<NUM> and the second connecting member is a spring member <NUM>-<NUM>, and the hook is connected to the spring member.

As shown in <FIG>, only the free end of the LED filament is hooked with an end of the long tube through the first connecting member (the hook) and the second connecting member. The second connecting member is a spring member, a hook or a hanging ring. The first connecting member may also be a spring member. The spring member can be provided with a hooking part for hooking, such as a hitch or a hanging ring, or the spring member can be provided without hook part.

To sum up, on a basis of a general idea of the present disclosure, it can be considered that two ends of the LED filament are the fixed end and the free end respectively, one end is connected to the power connection assembly through the first connecting member, and the other end is also connected to another power connection assembly through the first connecting member, as shown in <FIG>.

On the basis of the general idea of the present disclosure, similarly in the light transmissive housing of the long tube shown in <FIG>, if only one end of the long tube is with the power connection assembly, the free end is connected to the end of the long tube through the first connecting member and the second connecting member, and the fixed end is directly and fixedly connected to the power connection assembly; or, the free end is connected to the end of the long tube through the first connecting member and the second connecting member, and the fixed end is connected to the power connection assembly through the first connecting member and the second connecting member.

This embodiment provides an LED filament that can be cropped based on any of Embodiments <NUM>-<NUM>. LED chips or LED beads in the LED filaments are connected in parallel between single or multiple series connected LED filaments, with a substrate being a flexible substrate, which can be cropped. Specifically, for convenience of use, it can be marked in a clipping position.

Not in accordance with the present invention, a characteristic scheme is disclosed in this embodiment, and it is considered that the second connecting member is the light transmissive housing. The first connecting member is a weight piece, and when the lamp is installed, the lamp line is hung and fixed by gravity with the weight piece. Because the LED filament is light, some heavy materials are usually prepared on a surface of the LED filament so as to realize natural hanging, but in this scheme, production cost is increased, and at the same time, aesthetics of the lamp line decreases. However, using the weight piece presents good effect.

A magnetic attractive LED filament lamp, as shown in <FIG>, includes a housing <NUM>', one or more LED filaments <NUM>', a lamp cover structure fixed with one end of the filament, and a lamp base connected with the other end of the filament. The lamp cover structure includes a first cover body <NUM> connected with the housing, and the lamp base includes a base cover body <NUM> connected with the housing. The housing is a transparent or translucent case;.

An outer surface of the housing of this embodiment is an arcuate surface, and an outer surface of the first cover body and the base cover body are arcuate surfaces adapted to the outer surface of the housing. A natural transition of a joint between the arcuate surfaces of the first cover body and the base cover body and the arcuate surface of the housing after the assembly, and smooth connection of several surfaces of an overall housing structure of the lamp can be ensured. Based on other structures, the housing can also be set with a geometrical body or other designed shapes.

As shown in <FIG>, <FIG>, a structure of the housing includes a short and round shape or a slender shape, that is, an aspect ratio of the housing can be adjusted as long as an arcuate surface structure is provided. Accordingly, a filament length, structures of the first cover body and the base cover body are further adjusted accordingly.

The lamp cover structure further includes an electrical connector <NUM>' and a second cover body <NUM>. The electrical connector is a component connected with a power supply, the electrical connector is connected with the first cover body, and the first cover body is connected with the second cover body. A control circuit board is installed between the first cover body <NUM> and the second cover body <NUM>, and the filament passes through the second cover body to be electrically connected with the control circuit board.

The housing is formed into a structure with hollow upper and lower end faces by injection molding, on which then the lamp cover structure and the lamp base are installed.

As shown in <FIG>, a structure and a preparation method of a first magnetic attractive member <NUM>' are provided. The first magnetic attractive member <NUM>' includes an internal insulator, and a magnetic material layer or a magnetizable material layer is provided outside the insulator. The internal insulator is taken for example as a <NUM> PP plastic ball as shown, which is then coated with an iron powder layer or an iron sheet with a thickness of <NUM>, is punched at a middle of the ball, and is electroplated after molding. A hole at the middle is configured to be connected with an end of the filament. Dimensions and materials disclosed in this embodiment and <FIG> are just examples, which can be referred by those skilled in the art to perform structural and technological adjustments.

As shown in <FIG>, another structure and preparation method are provided. The first magnetic attractive member <NUM>' includes a magnetic material member or a magnetizable material member therein, and an insulating material layer is provided outside the magnetic material member or the magnetizable material member. As shown in <FIG>, the insulating material member is taken as for example an ABS or silica gel ball, or the like, which is punched in the ball and into which a magnet is placed, then the magnet is fixed inside the insulating material member with glue, and finally the insulating material member is coated externally, for example coated with chrome. An upper part of the hole at the middle with the magnet being placed is configured to be connected with the end of the filament.

Dimensions and materials disclosed in this embodiment and <FIG> are just examples, which can be referred by those skilled in the art to perform structural and technological adjustments.

Another conceivable first magnetic attractive member is further provided in this embodiment, that is, a mixed fixture is formed by using the mixed magnetic material or magnetizable material.

Selection of the magnetic material or the magnetizable material is based on material matching of the second magnetic attractive member. The first magnetic attractive member disclosed in this embodiment adopts the magnet (the magnetizable material), the iron powder and the iron sheet (the magnetic material) as examples, which can be changed by referring to material selection of the second magnetic attractive member according to core idea of this scheme.

The filament is an unshaped filament made of a flexible substrate, which naturally droops under influence of gravity, and is attracted and fixed in contact or in non-contact by the second magnetic attractive member and the first magnetic attractive member. A non-contact mode in shown in the figure, and connection is made by a magnetic force (an attractive force).

In another scheme, the filament is a shaped filament with a bent structure, a fold structure or a spiral structure. In this case, a substrate of the filament is a flexible substrate or a rigid substrate, the rigid substrate can be a PCB or an aluminum substrate, and the flexible substrate can be a FPC substrate.

Specifically, the filament in this embodiment includes more than one luminescent particle and at least two sections of conductive components. The luminescent particles can be LED chips. That is, the luminescent particles can be LED bare dies directly fixed to a strip-shaped substrate.

Further, the filament also includes a protective layer, and luminescent particles are positioned in a light transmissive protective layer; part or all of the conductive components are located in the light transmissive protective layer. In this embodiment, the luminescent particles and the conductive components are both located in the light transmissive protective layer to shape the filament.

The LED chips in this scheme are different from the traditional LED lamp beads for which there is a large difference in finished filament products and there is a thick packaging layer outside the LED lamp beads because the lamp beads are packaged LED chips, and when the traditional LED lamp beads are made into a filament or lamp line, defects exist as follows: <NUM>) a distance between two luminescent particles is large, and when the luminescent particles are connected in series or in parallel to form a straight line, there will be an obvious gap with low light intensity after lighting, resulting in a whole lamp line to be connected point light sources, instead of a complete filament with visually indistinguishable light intensity difference. <NUM>) Because the LED beads is much larger than the LED chips in volume, which, when connected, are with a large cross section, and "filament" effect cannot be achieved and its preparation is rough, and filament luminous effect cannot be achieved after the LED beads are further made into the lamp line. This problem can be solved by the LED chips well.

The substrate adopts a strip-shaped substrate or a spiral substrate, and the LED chip and the conductive components mounted on the strip-shaped substrate or the spiral substrate.

It can be conceived that a substrate structure is not adopted in the filament, and the substrate can be directly replaced with an electrical connection wire, and then the protective layer can be arranged outside the LED chips and the electrical connection wire.

For strength of a lamp bar, the substrate is provided with a reinforcing member, such as a reinforcing rib <NUM> matching the length of the filament. As shown in <FIG>, a reinforcing rib structure is provided at a back of the filament, and as shown in <FIG>, an LED chip structure is provided at a front of the filament.

A reinforcing structure, such as a metal or nonmetal reinforcing rib such as a nylon reinforcing rib, can also be installed in the protective layer along a length direction of the filament. For better reinforcing effect, one reinforcing rib can be arranged on both sides of the filament or reinforcing ribs can be arranged in the filament structure according to positions. The structures with and without the substrate described above are adaptable to improvement from the reinforcing rib.

Other reinforcing structures include shaping pieces <NUM> installed at both ends of the filament.

The light transmissive housing in this embodiment is a transparent or translucent housing. Taking the transparent housing as an example, glass, plastic and other materials can be adopted to be made into a housing with effect of cutfaces of crystals, and this kind of housing can not only reveal light source effect of an internal lamp line, but also refract other brilliance through the housing.

For example, ordinary glass with a smooth surface is fired into a glass housing with gray gradient, which is small at top and big at bottom and with an arcuate surface. Further, colors of outer surfaces of the lamp cover structure and the lamp base are set to be similar to that of the glass housing, with a natural and aesthetic overall color.

On a premise of a cost-saving and rapid process, a fully transparent or translucent housing with color was prepared by a resin molding process.

An LED filament lamp, referring to the structure according to Embodiment <NUM> and referring to <FIG>, is provided. The lamp base further includes an outer structure <NUM>, which is a convex structure installed inside the base cover body and is provided with a second magnetic attractive member.

The convex structure of the outer structure is a cone, the second magnetic attractive member is arranged in the cone, a placing cavity <NUM> is arranged in the cone, the second magnetic attractive member is placed in the placing cavity, and the second magnetic attractive member <NUM>' is installed proximate to an apex of the cone.

The cone includes a conoid or a pyramid. A pyramidal surface of the pyramid is any of one or more combination of a planar surface, a concave arcuate surface and a convex arcuate surface; and a conical surface of the conoid is any one of a planar surface, a concave arcuate surface and a convex arcuate surface. A cone with the planar surface can be understood as a straight line connecting left and right sides of a longitudinal section of the cone.

As other embodiments, the second magnetic attractive member can also be arranged at other positions, so long as adsorption connection or magnetic connection with the first magnetic attractive member can be achieved on a premise that processes allow.

An LED filament Or lamp, referring to the structure according to Embodiment <NUM> and referring to <FIG> and <FIG>, is provided. The second magnetic attractive member is a convex structure fixed to the base cover body, and an apex of the convex structure is installed towards the lamp cover structure. That is, the whole convex structure is a magnetic structure, the second magnetic attractive member is a cone fixed to the base cover body, and an apex of the cone is installed towards the lamp cover structure. The cone includes a conoid or a pyramid, and a surface of the cone is a concave arcuate surface or a convex arcuate surface.

An LED light-emitting lamp board <NUM> is installed below the lamp structure, and a plurality of LED beads or LED chips <NUM>-<NUM> are installed on the LED light-emitting lamp board. Arrangement density of the LED beads or LED chips on the lamp board can be adjusted, and their shapes can also be designed as desired.

As shown in <FIG>, a light-emitting surface of the LED light-emitting board is installed in a direction toward an interior space of the lamp. Combined with the schemes according to Embodiment <NUM> to Embodiment <NUM>, effect of simultaneous light emission at two positions obviously can be realized, with more distinctive light-emitting effect compared with a traditional lamp structure.

There is a through hole <NUM>-<NUM> at a middle of the LED board, and the filament passes through the through hole to be connected with the control circuit board installed on a back of the LED board.

For a specific installation position of the LED light-emitting board, reference can be made to a position shown in <FIG>. The second cover body is located below the LED light-emitting board. In this embodiment, the second cover body needs to adopt a light transmissive cover body.

As disclosed in Embodiment <NUM>, the reinforcing member is arranged in the filament. Strength of the filament is enhanced with a technical feature that the reinforcing member includes reinforcing ribs arranged along the length direction of the filament. Further, decorative fittings <NUM> can be provided outside the filament. As shown in <FIG>, an installation method of the filament can be that a stopper is provided at a tail end of the filament and the decorative fittings with the through hole are sleeved on the filament. As shown in <FIG>, the decorative fittings can also be arranged at certain intervals, and the decorative fittings can be installed by an adhesive member, such as glue. Other conceivable methods include adhering the decorative fittings directly outside the filament.

The decorative fittings mentioned here are crystal fittings, glass beads and other similar decorations, which, when used in this scheme, are not only used for decoration. For example, the outer surface of the lamp bead can have cutfaces or textures, which are aesthetic in appearance and refract light with different luminous effects, thus avoiding direct glare light to a certain extent. A light emission angle can also be varied according to cutface design of the decorative fittings.

It should be noted that a shape of the light transmissive housing is changeable, that is, it can be circular, fan-shaped or a hollow frame housing composed of brackets. Shapes, structures and sizes of the first suction member and the second suction member are also variable.

It should be noted that the LED filament lamp in the present disclosure can be a bulb lamp, a fluorescent lamp, or a light fixture. When it is the light fixture, the light transmissive housing is a lampshade; when it is the bulb lamp, the light transmissive housing is a bulb housing made of glass, plastic or other materials. The connection of the present disclosure can be a fixed connection or a movable connection, such as magnetic adsorption. The fixed connection is to fix the connecting part directly in production, so it cannot be adjusted.
