Description

Flat panel lighting improvement

This creation is about the improvement of a flat panel lamp, especially a flat panel lamp that can solve the problem of uneven brightness and darkness, and can also increase the illumination of the whole flat panel lamp.

With the rapid development of technology, products that require multi-industry are oriented toward light and thin design, which is to reduce the weight and thickness of the products. Among them, the light-emitting diodes are the most widely used, which can be used to make LCD TVs. Indoor lighting, etc., more commonly used such as LED light panels, that is, a plurality of LED lamp heads are arranged in an array in a lampshade, and a corresponding driving circuit is arranged in the lampshade, although the structure is simple and practical, the LED lamp The disc is in the form of a direct-lit LED light source, which is more glaring and produces poor light uniformity (less than 70% uniformity). Therefore, some manufacturers have developed a class of LED flat lights.

The LED flat lamp is planar and the components inside are also planar. As shown in the first figure, the planar light guide plate 12 is mainly installed in a bottom plate 11, and is installed at the side of the light guide plate 12. The LED light bar 13 has a plurality of reflections under the action of the light guide plate 12 to achieve uniformity and prevent glare.

However, since the light guide plate in the LED flat lamp has a large size and is easily deformed, in the embodiment shown in the figure, a curved warped portion 121 is formed, and the curved portions 121 change the original light path. The bright and dark areas are formed, so that the light of the overall LED flat lamp does not perform well.

In view of this, the author is providing a flat panel lamp improvement that can solve the problem of unevenness in brightness and darkness, and can also increase the illumination of the overall flat lamp.

In order to achieve the above, the flat panel lamp modification of the present invention comprises at least a light guiding structure, at least one reflecting member, at least one diffusing member and a light source module, wherein the light guiding structure has a bottom surface and a light emitting surface opposite to the bottom surface. And the side of the light-emitting surface is located at the bottom surface of the light-conducting structure, the diffusing member is located between the light-guiding structure and the reflecting member, and the light source module is located at the light guiding The side of the structure.

Among them, the use of the diffuser can solve the problem of uneven brightness and darkness, and can also increase the illumination of the overall flat panel light.

According to the above technical feature, the light guiding structure has at least one protrusion arranged in the first direction, the reflecting member has at least one protrusion arranged in the first direction, and the diffusion member has at least one along the first direction Arrange the protrusions.

According to the above technical feature, the reflective member can be a back plate of a flat panel light fixture.

According to the above technical feature, the light guiding structure has four sides between the bottom surface and the light emitting surface, and the light source module is located at least on one side.

According to the above technical feature, the light source module further has a plurality of light emitting diodes.

The third figure is an exploded view of the structure of the flat panel lamp in this creation.

The fourth picture is a cross-sectional view of the structure of the flat panel lamp in the creation.

The fifth picture is a perspective view of another structure of the flat panel lamp in the creation.

The characteristics of this creation can be clearly understood by referring to the detailed description of the drawings and the examples.

For example, the second figure is a three-dimensional structure diagram of the creative flat lamp, the third figure is an exploded view of the structure of the creative flat lamp, and the fourth figure is an exploded view of the structure of the flat lamp in the present creation, the flat lamp 2 of the present creation is at least The light guiding structure 21, the at least one reflecting member 22, the at least one diffusing member 23, the light source module 24, and the frame body 25 are included.

The light guiding structure 21 has a bottom surface 211, a light emitting surface 212 opposite to the bottom surface 211, and a side surface 213 between the bottom surface 211 and the light emitting surface 212. In the embodiment shown in the figure, the bottom surface 211 of the light guiding structure. There are four side surfaces 213 between the light-emitting surface 212 and a light-emitting surface of the light guiding structure (not shown).

The reflector 22 is located at the bottom surface 211 of the light guiding structure 21; the reflecting member 22 can be a reflective sheet, a reflecting plate, or can be a back plate of a flat panel lamp.

The diffusing member 23 is located between the light guiding structure 21 and the reflecting member 22.

The light source module 24 is disposed on at least one side 223 of the light guiding structure 21, and the light source module 24 further has a plurality of light emitting diodes 241. In the embodiment shown in the figure, the light emitting diodes 241 are The light source module is located at one of the other sides of the light guiding structure.

The frame 25 is used to fix the light guiding structure 21, the reflector 22, the diffuser 23, and the light source module 24.

The light source of the light source module 24 enters from the side 213 of the light guiding structure, and the light is reflected by the light guiding structure 21 and the reflecting member 22 to achieve uniformity and prevent glare; Using the diffuser The light guiding structure 21 is disposed between the light guiding structure 21 and the reflecting member 22 to increase the light diffusion effect. Even if the light guiding structure 21 is deformed and bent due to the large size, the diffusion effect of the diffusing member 21 can be utilized to solve the uneven brightness and darkness. The problem can also increase the illumination of the overall flat panel.
