TECHNICAL FIELD

The present disclosure relates to the technical field of lighting and in particular to a lighting device.

BACKGROUND

At present, the height of the lighting device is usually adjusted through a parallel four-bar structure or a hose structure, which generally has the problems of a small moving range, troublesome assembly and use, large volume, and inconvenient storage and carrying. In addition, the angle of the lighting device can only be adjusted in the vertical direction, and the range of adjustment is very limited, which is impossible to adjust from a larger angle. The design of the existing lighting device results in a poor user's experience.

The first aspect of the present disclosure provides a lighting device, which includes:a base assembly provided therein with a circuit board;a telescopic assembly provided with a fixed end and a free end that are arranged oppositely, where the fixed end is connected to the base assembly; anda lighting assembly rotatably connected to the free end to rotate axially and radially along the free end and provided with a lighting element electrically connected to the circuit board.

The second aspect of the present disclosure further provides a lighting device, which includes:a base assembly provided therein with a circuit board;a telescopic assembly provided with a fixed end and a free end that are arranged oppositely, where the fixed end is connected to the base assembly, and the free end is configured to move relative to the fixed end to be close to and away from the base assembly;a lighting assembly rotatably connected to the free end to rotate relative to the free end and provided with a lighting element electrically connected to the circuit board;a spring wire provided with one end electrically connected to the circuit board; anda first connector and a second connector, which are electrically connected and arranged inside the telescopic assembly at the free end, where the other end of the spring wire passes through a gap between the telescopic assembly and the base assembly, then bends and extends into the telescopic assembly, and is electrically connected to the first connector; and the second connector is electrically connected to the lighting element.

In conclusion, the lighting device includes the base assembly provided therein with the circuit board; the telescopic assembly provided with the fixed end and the free end that are arranged oppositely, where the fixed end is connected to the base assembly; and the lighting assembly rotatably connected to the free end to rotate relative to the free end, where the lighting assembly is provided with the lighting element electrically connected to the circuit board. The extension and retraction of the lighting assembly and the lighting element are realized through the telescopic assembly, such that the height adjustment of the lighting device can be realized in a large range, which is convenient for storage and carrying.

REFERENCE NUMERALS

The implementation of the objective, functional characteristics, and advantages of the present disclosure will be further described below with reference to the embodiments and the drawings.

DETAILED DESCRIPTION OF THE EMBODIMENTS

It should be noted that all the directional indications (such as upper, lower, left, right, front, and rear) in the embodiments of the present disclosure are merely used to explain relative position relationships or movement positions of the components in a specific orientation (as shown in the figures). If the specific orientation changes, the directional indication also changes accordingly.

Further, the technical solutions of the embodiments may be combined with each other on the basis that the combination is implementable by those of ordinary skill in the art. In case a combination of the technical solutions is contradictory or infeasible, such a combination is deemed not to fall within the protection scope of the present disclosure.

The present disclosure provides a lighting device.

As shown inFIGS.1to6, the lighting device includes base assembly100provided therein with circuit board110; telescopic assembly200provided with fixed end210and free end220that are arranged oppositely, where the fixed end210is connected to the base assembly100; and lighting assembly300rotatably connected to the free end220to rotate axially and radially along the free end220, where the lighting assembly300is provided with lighting element310electrically connected to the circuit board110.

The base assembly100may be placed on the ground or adsorbed to an iron article. The base assembly100may also be adsorbed in a region at a high position such as an iron ceiling to realize a different use scenario. The use scenarios of the lighting device are not limited herein.

The telescopic assembly200can adapt to lighting scenarios of different heights. The length of the telescopic assembly200may also be appropriately increased according to different lighting scenarios. To store the lighting device, the telescopic assembly200is retracted such that the lighting assembly300and the base assembly100can be stored together, thereby reducing the occupied space of the lighting device and facilitating the carrying of the lighting device.

The free end220is an end that can be stretched or contracted, and the fixed end210is an end that is configured to fix the telescopic assembly200. When the telescopic assembly200is in a storage state, the free end220is stored in the fixed end210. When the free end220is pulled out from the fixed end210, the telescopic assembly200is in an extended state. Of course, in this embodiment, the telescopic assembly200further has a fully extended or partially extended state, which can be set according to the actual lighting scenario of the lighting device and is not limited herein.

Further, the lighting assembly300is provided on the free end220of the telescopic assembly200. The lighting assembly300can move in a direction away from the fixed end210with the extension of the free end220, thereby increasing the height of the lighting assembly300. Alternatively, the lighting assembly300can move in a direction toward the fixed end210with the retraction of the free end220, thereby reducing the height of the lighting assembly300. In addition, since the lighting assembly300is rotatably connected to the free end220, the lighting assembly300is rotatable axially and radially along the free end220. Therefore, the lighting element310is adjustable in height and is rotatable axially and radially along the free end220.

The lighting element310is a light-emitting plate, which may include a plurality of light-emitting diode (LED) lamps in parallel and/or in series.

In the technical solution provided by the present disclosure, the extension and retraction of the lighting assembly300and the lighting element310are realized through the telescopic assembly200, such that the height adjustment of the lighting device can be realized in a large range, which is convenient for storage and carrying. Since the lighting assembly300is movably connected to the free end220, the lighting assembly300is rotatable axially and radially along the free end220. That is, the angle of the lighting assembly300can be adjusted in the horizontal and vertical directions to meet different lighting angles, thereby improving the user's experience.

In this embodiment, the base assembly100includes base120, and main body130and guide rail element140both of which are hollow-through. The guide rail element140has one end connected to the main body130and the other end connected to the base120. An inner space of the main body130is communicated with an inner space of the guide rail element140. The circuit board110is provided in the main body130. The fixed end210passes through the inner space of the main body130and the inner space of the guide rail element140in sequence and is connected to the base120.

Therefore, the base assembly100may be placed on the ground or adsorbed to an iron article to realize a different use scenario, which is not limited herein.

The main body130is separated from the base120through the guide rail element140. In this embodiment, in order to fix the fixed end210of the telescopic assembly200, the main body130and the guide rail element140are arranged in a hollow-through structure, and the inner space of the main body130is coaxial with the inner space of the guide rail element140. The fixing end210can directly pass through the inner space of the main body130and the inner space of the guide rail element140and be fixed to the base120. In this way, the telescopic assembly200can be stored in the inner space of the main body130and the inner space of the guide rail element140, thereby reducing the space occupied by the telescopic assembly200.

The circuit board110is provided in the main body130. Of course, in this embodiment, the circuit board100may also be provided in the base120to omit the main body130, thereby saving costs.

Further, the lighting device further includes spring wire400provided with one end electrically connected to the circuit board110; and first connector500and second connector600that are electrically connected. The first connector500and the second connector600are arranged inside the telescopic assembly200at the free end220. The other end of the spring wire400passes through a gap between the telescopic assembly200and the guide rail element140, then bends and extends into the telescopic assembly200, and is electrically connected to the first connector500. The second connector600is electrically connected to the lighting element310.

The maximum outer diameter of the telescopic assembly200is smaller than an inner diameter of the guide rail element140, such that the gap is formed between the telescopic assembly200and the guide rail element140. Thus, one end of the spring wire400is electrically connected to the circuit board110. The other end of the spring wire passes through the gap, bends and extends to the interior of the telescopic assembly200, and is electrically connected to the first connector500. The first connector500is electrically connected to the second connector600, and the second connector600is electrically connected to the lighting element310. That is, the circuit board110is electrically connected to the lighting element310through the spring wire400, the first connector500, and the second connector600, thereby controlling the lighting state of the lighting element310.

Further, in order to electrically connect the first connector500and the second connector600, the first connector500may be provided with connecting receptacle510. The first connector500includes positive elastic piece520and negative elastic piece530both of which are connected to the other end of the spring wire400.

The connecting positive electrode630is fitted to the positive elastic piece520in an elastic manner. The connecting negative electrode620is fitted to the negative elastic piece530in the elastic manner. The main wire610is electrically connected to the lighting element310.

The connecting positive electrode630of the second connector600is inserted in the connecting receptacle510of the first connector500, such that the connecting positive electrode630is fitted to the positive elastic piece520in the elastic manner to realize point-contact conductivity. The connecting negative electrode620of the second connector600is fitted to the negative elastic piece530in the elastic manner to realize point-contact conductivity. The first connector500and the second connector600are electrically connected.

Optionally, the gap between the connecting positive electrode630and the connecting negative electrode620may be filled with an insulating material. Alternatively, an insulating material such as insulating glue is provided on the surface of the connecting positive electrode630or the connecting negative electrode620. The insulation design is not limited herein.

Further, referring toFIG.7, the lighting assembly300further includes radiator320. The radiator320is provided with rotating groove321. The lighting element310is fitted to the radiator320to dissipate heat of the lighting element310through the radiator320. The lighting element310is in close contact with the radiator320to effectively guide the working heat to the radiator320to protect the lighting element310from damage due to high temperature. A side of the radiator320away from the rotating groove321is provided with mounting groove322, and the lighting element310is provided in the mounting groove322.

Optionally, the radiator320is made of an aluminum alloy. Alternatively, the radiator320may be made of other material with high heat dissipation performance, which is not limited herein.

In order to protect the lighting element310, the lighting assembly further includes transparent protective cover330. The transparent protective cover330is provided on the mounting groove322to protect the lighting element310. Light from the lighting element310can directly penetrate the transparent protective cover330, such that the light can be uniformly scattered to realize a good lighting effect.

Further, the lighting assembly300includes radiator rear cover340that covers the rotating groove321. The working heat of the lighting element310is transmitted to the radiator320and the radiator rear cover340to protect the lighting element310from damage.

Further, in order to realize the rotation of the lighting assembly300around the free end220, the lighting device includes connecting element700. The connecting element700has first connecting part710and second connecting part720connected to the first connecting part710. The first connecting part710is inserted at the free end220and connected to the second connector600in the telescopic assembly200. The connecting element700is rotated with the first connecting part710as a rotating shaft. The second connecting part720is provided in the rotating groove321, and the lighting assembly300is rotated with the second connecting part720as a rotating shaft.

Optionally, the connecting element700is a T-shaped connector. The first connecting part710of the T-shaped connector is inserted at the free end220and connected to the second connector600in the telescopic assembly200. The second connecting part720of the T-shaped connector is provided in the rotating groove321to make the lighting assembly300rotate axially and radially along the free end220.

Further, a portion where the connecting positive electrode630exceeds the connecting negative electrode620has a circular structure, and the connecting receptacle510is a circular connecting receptacle. After the connecting positive electrode630with the circular structure is inserted into the circular connecting receptacle, the second connector600and the first connector500can realize 360° infinite rotation while being electrically connected.

Further, the lighting device includes damping rubber ring730. The damping rubber ring730is sleeved on the periphery of the second connecting part720to improve friction between the second connecting part720and the radiator320during rotation. In this way, the second connecting part is not easily loosened or shaken or does not make abnormal noises, and its hand sensory feel is improved.

An interior of the first connecting part710is communicated with an interior of the second connecting part720. The main wire610passes through the interior of the first connecting part710and the interior of the second connecting part720in sequence and is electrically connected to the lighting element310.

The second connector600is externally provided with a telescopic tube rubber sleeve. An outer wall of the telescopic tube rubber sleeve is closely connected to the telescopic assembly200. The second connector600has a smaller end passing through the telescopic tube rubber sleeve and a larger end with a diameter greater than the inner diameter of the telescopic tube rubber sleeve, such that the larger end of the second connector600is clamped inside the telescopic assembly200by the telescopic tube rubber sleeve without falling out. Meanwhile, due to the circular plug-in design between the telescopic tube rubber sleeve and the second connector600, the second connector600and the telescopic tube rubber sleeve are rotatable relatively.

Referring toFIGS.1,2, and5, the circuit board110is provided with charging interface112. The main body130is provided with charging through-hole131and mounting through-hole132both of which run through an outer wall. The charging interface112is exposed from the charging through-hole131. The lighting device further includes battery800. The battery800is provided in the main body130and is electrically connected to the circuit board110. An external power supply device passes through the charging through-hole131to be connected to the charging interface112to charge the battery800. The lighting device further includes dust cover900. The dust cover900is provided in the mounting through-hole132and covers the charging through-hole131.

Of course, in this embodiment, the circuit board110is provided with a power output interface113. The main body130is further provided with power output through-hole133running through the outer wall. The power output interface113is exposed from the power output through-hole133. The power output interface113may be connected to an external electric device (such as a mobile phone or tablet) to charge the electric device.

Of course, the circuit board110is further integrated with a power key, a power indicator, and other components that are exposed to the main body130.

The dust cover900is clamped in the mounting through-hole132through a clamping point, such that the dust cover900will not be separated from the main body130. An outer wall of the dust cover900is provided with a protruding clamping point, and an outer shell of the main body is provided with a clamping point groove. The protruding clamping point and the clamping point groove are fitted with each other. When the charging interface is not used, the dust cover900can be tightly fitted to an outside of the charging through-hole131and the power output through-hole133due to the tight fit between the protruding clamping point and the clamping point groove. The dustproof plug can effectively protect dust and other foreign matters from entering the lighting device to realize a dustproof and beautiful effect. In addition, the dust cover900may be provided with a pull position to open the dust cover900.

Referring toFIGS.1,5, and8, in this embodiment, in order to improve the stability of the base assembly100, the lighting device further includes sliding element1000, a plurality of support legs1100, support rod1200, and support and fixing cover1300. The sliding element1000is slidably sleeved on the guide rail element140. The support legs1100each are provided with rotating end1110, and the rotating end1110is rotatably connected to the sliding element1000, such that the support legs1100each are rotatable toward or away from the sliding element1000with the rotating end1110as a rotating shaft. The support rod1200is provided with first connecting end1210and second connecting end1220that are arranged oppositely. The first connecting end1210is rotatably connected to a central part of the support leg1100through the support and fixing cover1300. The second connecting end1220is rotatably connected to the base120.

The sliding element1000is slidable freely on the guide rail element140. The sliding element1000is configured to move to the bottommost position to contact the base120, and the sliding element will not slide out of the guide member140due to the limitation by the base120. The support legs1100each are connected and fixed to sliding element1000through the rotating end1110. The support legs1100each are rotated with the rotating end1110as a rotating shaft. The support rod1200is provided between the support leg1100and the base120. The support rod1200has one end close to the support leg1100serving as the first connecting end1210and the other end close to the base120serving as the second connecting end1220. The support rod1200rotates with the first connecting end1210as the rotating shaft. Alternatively, the support rod1200is rotated with the second connecting end1220as a rotating shaft. The rotating end1110, the first connecting end1210, and the second connecting end1220form a triangular structure. That is, the support leg1100, the support rod1200, and the sliding element1000form a triangle structure, which provides high stability and strength.

When the sliding element1000is forced to move towards the base120, the distance between the rotating end1110and the second connecting end1220is shortened. The downward pressure of the sliding element1000and the upward supporting force of the base120generate a resultant force toward the first connecting end1210. The support leg1100is opened outward under the action of the resultant force. That is, the support leg1100is opened to increase the radius of a ground support point. The design effectively improves the stability of the lighting device when the lighting device stands, such that the lighting device can stand stably when tilted.

Correspondingly, when the sliding element1000is pulled upward, the acting force is the opposite. The support leg1100is closed inward under this force. Therefore, the support leg1100can be opened and closed by moving the sliding element1000. In the storage state, the lighting device has a smaller volume and is easy to carry.

Further, a plurality of grooves141are arranged on an outer wall of the guide rail element140. The lighting device further includes a plurality of rubber pad elements1400. The plurality of rubber pad elements1400are arranged in the sliding element1000. A plurality of positioning posts1410are provided on surfaces of the rubber pad elements1400away from the sliding element1000. The positioning posts1410each are arranged in one groove141.

There is a gap between the inner side of the sliding element1000and the outer side of the guide rail element140. In this embodiment, in order to prevent the sliding element1000from loosening, the rubber pad elements1400are provided in the gap between the inner side of the sliding element1000and the outer side of the guide rail element140. One side of each of the rubber pad elements1400is provided in the sliding element1000, and the surface of each of the rubber pad elements1400away from the sliding element1000is provided with the positioning post1410. The positioning posts1410are embedded in the grooves141, such that the rubber pad elements1400and the grooves141are always squeezed and stressed, thereby increasing the friction between the sliding element1000and the guide rail element140.

A side of each of the support legs1100away from the rotating end1110is provided with magnetic suction piece1120. When the base assembly100is fixed on a wall, a floor, or a ceiling, the base assembly is adsorbed onto a magnetic material on the wall, the floor, or the ceiling through the magnetic suction piece1120. The design further strengthens the lighting device, improves the stability of the lighting device, and prevents the light from shaking.

Optionally, the magnetic suction piece1120may be a strong magnet, and the magnetic material may also be a strong magnet. Alternatively, the magnetic suction piece1120may be a strong magnet, and the magnetic material may be a material that can be adsorbed by the magnet, such as iron, cobalt, nickel or an alloy thereof. Alternatively, the magnetic suction piece1120may be a material that can be adsorbed by the magnet, such as iron, cobalt, nickel, or an alloy thereof, and the magnetic material may be a strong magnet. The materials of the magnetic suction piece and magnetic material are not limited herein.

Further, in order to realize the extension and retraction of the telescopic assembly200, the telescopic assembly200includes a plurality of telescopic rods connected head-to-tail. The inner diameters of the telescopic rods decrease progressively from the fixed end210to the free end220. When the telescopic assembly200is in an extended state, the inner diameters of telescopic rods gradually decrease in a direction from the base assembly100to the lighting assembly300. That is, the inner diameter of the telescopic rod closest to the base assembly100is the largest, such that other telescopic rods can be stored in the telescopic rod with the largest inner diameter.

Further, it is necessary to prevent one telescopic rod from separating from the other telescopic rod during the extension process. Referring toFIG.6, taking telescopic rod200aand telescopic rod200bas examples, the inner side of the head of the telescopic rod200ais provided with first rubber pad201, and the outer side of the tail of the telescopic rod200bis provided with second rubber pad202. The outer diameter of the second rubber pad202is greater than the inner diameter of the first rubber pad201. When the tail of the telescopic rod200bis sleeved on the head of the telescopic rod200aand the telescopic rod200bextends away from the telescopic rod200a, the second rubber pad202is clamped at the first rubber pad201to prevent the telescopic rod200bfrom sliding out of the telescopic rod200aduring the extension process. Every two adjacent telescopic rods are limited at a connection thereof by rubber pads, or by other soft materials. The limiting means are not limited herein.

The first rubber pad201and the first telescopic rod200a, as well as the second rubber pad202and the telescopic rod200b, are connected by adhesive glue or other means. The design realizes the stable connection between the first rubber pad201and the telescopic rod200a, as well as between the second rubber pad202and the telescopic rod200b.

Optionally, the telescopic rods are made of aluminum. Alternatively, the telescopic rods may also be made of other materials, such as aluminum alloy, copper, iron, or a composite material, which is not limited herein.

In conclusion, the lighting device includes the base assembly100provided therein with the circuit board110; the telescopic assembly200provided with the fixed end210and the free end220that are arranged oppositely, where the fixed end210is connected to the base assembly100; and the lighting assembly300rotatably connected to the free end220to rotate axially and radially along the free end220, where the lighting assembly300is provided with the lighting element310electrically connected to the circuit board110. The extension and retraction of the lighting assembly300and the lighting element310are realized through the telescopic assembly200, such that the height adjustment of the lighting device can be realized in a large range, which is convenient for storage and carrying. Since the lighting assembly300is movably connected to the free end220, the lighting assembly300is rotatable axially and radially along the free end220. That is, the angle of the lighting assembly300can be adjusted in the horizontal and vertical directions to meet different lighting angles, thereby improving the user's experience.

The foregoing are merely preferred embodiments of the present disclosure, and the scope of the present disclosure is not limited thereto. Any equivalent change made based on the content of the specification and drawings under the inventive concept of the present disclosure or direct/indirect application thereof in other related technical fields should fall within the protection scope of the present disclosure.
