It needs to be stated that the embodiments and the features in the embodiments in the present disclosure can be combined with one another under the situation of no conflict.

The embodiments of the present disclosure are described in detail below with reference to the drawings, so that those skilled in the art can easily implement the present disclosure. The present disclosure can be embodied in a variety of different forms and is not limited to the embodiments described herein.

In order to clarify the present disclosure, components that are not related to the description are omitted, and the same or similar components are denoted by the same reference numerals throughout the specification.

Throughout the specification, when a component is “connected” with another component, this includes not only the “direct connection” but also the “indirect connection” in which other elements are placed therebetween. In addition, when a certain component “includes” a certain element, unless otherwise stated, other elements are not excluded, which means other elements may be included.

When a component is referred to as being “above” another component, it may be directly above the other component; however, other components may also be accompanied between the two components. In contrast, when a component is referred to as being “directly above” another component, there are no other components between the two components.

Although the terms first, second, etc. are used herein to describe various elements in some embodiments, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, the first interface and the second interface. In addition, as used herein, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should be further understood that the terms “comprise”, “include” indicate that there are the described features, steps, operations, elements, components, items, categories, and/or groups, but the existence, appearance, or addition of one or more other features, steps, operations, elements, components, items, categories, and/or groups are not excluded. The terms or and “and/or” are used herein to be interpreted as inclusive or meaning any one or any combination. Thus, “A, B or C” or “A, B and/or C” means “any one of the following: A; B; C; A and B; A and C; B and C; A, B and C”. An exception to this definition occurs only when a combination of elements, functions, steps or operations are inherently mutually exclusive in some manner.

The terminology used herein is only for the purpose of the description of special embodiments, and is not intended to limit the present disclosure. The singular form as used herein includes plural forms as long as the statement does not explicitly indicate the opposite. The word “include” used in the specification means the materialization of the specific features, regions, integers, steps, operations, elements and/or components, and does not exclude the existence or addition of other features, regions, integers, steps, operations, elements and/or components.

Terms referring to relative spaces such as “below”, “above”, etc. may be used to more easily illustrate the relationship of one component to another component illustrated in the drawings. Such terms refer to not only the meanings indicated in the drawings, but also other meanings or operations of the device in use. For example, a component that is described as “below” other components is described as “above” other components if the device in the drawings is turned over. Therefore, the term “below” is used to include all of the above and under. The device can be rotated by 90° or other angles, and terms representing relative space are also explained accordingly.

The structure of the light emitting part of the traditional table lamp holder or gallery lamp holder is generally straight-emitting or side-emitting. The adjustment of the light angle depends on reflection, refraction and scattering, resulting in great loss of luminous efficiency. Moreover, such a lamp holder tends to form glare when emitting light, and not all points on the light spot formed by the irradiation are uniform in brightness. The brightness near the lamp holder is high, while the brightness away from the lamp holder is low. In addition, the current lamp holders are always designed to be large to achieve large-area irradiation and uniformity. The present disclosure provides a lamp holder assembly and table lamp thereof, to solve at least one of the above-mentioned problems.

It needs to be stated that the lamp holder assembly described in the present disclosure may be used in various lamp bodies or lamp scenarios such as table lamps, gallery lamps, shop window lamps, cabinet lamps and the like. Preferably, the lamp holder assembly described in the present disclosure is applicable for a table lamp.

FIG. 1shows an overall schematic diagram of a lamp holder assembly according to an embodiment of the present disclosure. As shown, the lamp holder assembly includes a housing110, a heat radiator120, a plurality of light-emitting devices130, and a lens140.

Generally speaking, the heat radiator120is placed in a receiving cavity of the housing110. The heat radiator120includes a platform121for attaching each of the light-emitting devices130. The lens covers an opening at one end of the housing110to fix the heat radiator120.

The light emitting angle of the traditional lamp holder component is adjusted mostly depends on reflection, refraction and scattering, which leads to a large loss of luminous efficiency. To solve this problem, the present disclosure divides the light emitting component into multiple parts to adjust the angle of the light emitter, so as to meet the illumination requirement.

In an embodiment, the housing110is a cylinder. One end of the housing110is provided with an opening. The housing110is reserved with a receiving cavity for placing the heat radiator120.

To facilitate installation, the housing110of the present disclosure is preferably a cylinder. However, it should be understood that the housing110of the present disclosure may also be a polygonal prism, such as a cube, a hexagonal prism, an octagonal prism, etc. Of course, those polygonal prisms may still be used for a heat radiator120fixed as a cylinder. That is, as long as the center of the heat radiator120is aligned with that of the housing110, the sides of the heat radiator120can be in contact with at least four sides of the housing110to achieve the fixation of the two. In addition, when the housing110is a polygonal prism, the lens140is a polygon corresponding to the polygonal prism.

In one or more implementable embodiments, the housing110is made of plastic for consideration of weight, heat radiation and cost.

It should be noted that at least one top surface of a platform121facing the light exiting direction (not shown inFIG. 1) has a certain slope relative to the horizontal direction perpendicular to the light exiting direction. The lens140includes a light exiting surface opposite to the top surface of each platform.

For the detailed internal structure of the housing110, the heat radiator120, the light-emitting device130in the lamp holder assembly, refer toFIG. 2. In addition, reference may also be made toFIGS. 3A and 3Bfor the schematic diagrams of the lens140from the normal viewing angle and the top viewing angle, and toFIG. 4for the side view of the lamp holder assembly.

As shown inFIG. 1orFIG. 2, the platform121and the light-emitting device130attached thereto are shown as only three in the present disclosure. However, in other implementable embodiments, they may also be two or more than three.

For example, assuming that the number of the platforms121is two, the top surface of one of the platforms121may have a certain slope, and the top surface of the other platform121does not have a slope relative to the horizontal direction. Alternatively, both of the top surfaces of the two platforms121have a certain slope, and the orientation of the top surface of each platform121may be set to be the same or different according to actual conditions.

When the number of the platform121is three or more, the number of the platform121with a top surface having a certain slope may be one, two, and three. In addition, when the number of the platform121with a top surface having a certain slope is two or three, the orientation of the top surface of each platform121may be set to be the same or different according to actual conditions.

In some implementable embodiments, the setting of the number of the platform121with a top surface having a certain slope may be adjusted in the design and production processing stages according to the applied scenario or actual needs, to ensure the maximum light exiting efficiency and irradiation area, so as to enlarge the irradiation area when the size of the lamp holder assembly is limited.

In other implementable embodiments, the slope of the platform121may be increased or decreased during the design and production processing stages according to actual needs, so as to adjust the irradiation angle of each light-emitting device130.

Further, to optimize the light-emitting angle and light-emitting efficiency of each light-emitting device130that attached to the platforms121in different orientations, the lens140is designed as an irregular plane. More specifically, the area corresponding to the top surface of each platform121is designed to be parallel to the light exiting surface141of the top surface of each platform121. That is, the light-emitting device130is attached to the top surface of the platform121. Since the light exiting surface141is parallel to the top surface of the platform121, the light exiting surface141is also parallel to the attached light emitting device130. Therefore, the maximum luminous efficiency and irradiation area can be ensured to enlarge the irradiation area when the size of the lamp holder assembly is limited.

In the present disclosure, a plurality of light emitting devices130with different angles are provided, and such setting makes the lamp holder much smaller than the traditional LED table lamp. Emitted lights of different angles lead to uniform illumination, which is unlike the traditional technology, in which the brightness near the lamp holder is high while the brightness away from the lamp holder is low. The present disclosure has multiple different light-emitting devices130, the brightness of all points on the light spots formed by the illumination of the table lamp is uniform.

In addition, the present application enables the light-emitting device130to emit light in a direct manner, minimizing light loss, and improving light emitting efficiency.

In this embodiment, the heat radiator120is a cylinder, one end of the heat radiator120includes an opening. A plurality of the platforms121and a plurality of heat radiation through holes122protrude from the heat radiator120.

Correspondingly, the lens140has a heat radiation hole142corresponding to each heat radiation through hole122.

In the present disclosure, the heat radiation through hole122corresponds to the heat radiation hole142, the heat generated by the light-emitting device130in the cavity of the heat radiator120can be emitted from the lamp holder assembly through the heat radiation through hole122and the heat radiation hole142, to achieve the heat exchange with the outside air and improve the heat radiation performance.

In this embodiment, the inner side surface of the housing110includes a plurality of blocking bars111to fix the heat radiator120by snap-fitting; and/or, the inner side surface of the housing110includes a plurality of main snap-fit posts112to snap-fit the lens140.

Correspondingly, the outer side surface of the heat radiator120is equidistantly provided with a plurality of heat radiation fence123. The space between two adjacent heat radiation fences123is used for fixing the plurality of blocking bars111on the inner side surface of the housing110by snap-fitting, and/or for passing through the plurality of main snap-fit posts112on the inner side surface of the housing110to snap-fit the lens140.

The blocking bar111enables the heat radiator120to be quickly aligned when placed in the housing110, and keeps the relative position of the housing110and the heat radiator120unchanged.

In this embodiment, the side of the lens140includes an auxiliary snap-fit post143which faces the backlight direction and is adapted to be snap-fitted with the plurality of main snap-fit posts112on the inner side surface of the housing110.

The main snap-fit post112and the auxiliary snap-fit post143are a set of snap-fit assembly. The main snap-fit post112and the auxiliary snap-fit post143both have a protrusion for snap-fitting at the heads thereof, which has certain elasticity. After the head of the main snap-fit post112contacts with the head of the auxiliary snap-fit post143for a certain distance, the protrusions of the two is snap-fitted with each other. The main snap-fit post112and the auxiliary snap-fit post143facilitate the installation and removal of the lens140.

In this embodiment, the heat radiator120is made of aluminum substrate material. The aluminum substrate material has good heat radiation capability. In addition, it can be seen from the above that the heat radiator120further improves the heat radiation performance through the heat radiation fence123and the heat radiation through hole122.

In this embodiment, the side surface of the housing110includes a first wire opening113. The side surface of the heat radiator120includes a second wire opening124corresponding to the position of the first wiring opening113for connecting the power supply wiring.

Preferably, the first wiring opening113and the second wiring opening124are aligned. On the one hand, the power supply wiring could be connected, on the other hand, support parts, such as table lamp arms, could be supported.

In this embodiment, the light-emitting device130is composed of a ceramic base and an LED chip. The light-emitting device130may be connected with an external power source (such as a table lamp main body) through the first wiring opening113and the second wiring opening124.

The lamp holder assembly of the present disclosure has a small structure, high space utilization, large irradiation area, and uniform illumination. The brightness of all points on the light spots formed by the illumination is uniform. The light is emitted in a direct manner, which minimizes light loss and improves light emitting efficiency.

The present disclosure further provides a lamp device, including a lamp holder assembly as described inFIGS. 1-2. In one or more embodiments, the lamp devices described in the present disclosure include, but are not limited to, lamp devices of various forms or functions such as table lamps, gallery lamps, shop window lamps, cabinet lamps and the like.
