Problems solved by technology

[0009] However, the front side of the second reflection mirror 96 reflects all the light emitted by the LED 92 without penetrating any light emitted by the LED 92. In this way, the back surface of the second reflection mirror 96 will still produce Dark areas, resulting in uneven light sources

Embodiment Construction

[0074] Referring to FIG. 5 a , FIG. 5 b and FIG. 5 c , they show a light emitting device packaging structure 100 according to a first embodiment of the present invention. The light emitting component packaging structure 100 includes a frame body 110 , at least one light emitting component 120 and a lens 130 . The frame 110 has an opening 112 , an inner side 114 and a bottom 116 , wherein the inner side 114 can be composed of at least one plane and / or at least one arc. The light emitting component 120 can be a light emitting diode (LED) or other light sources with high light intensity and directivity. The light emitting component 120 is located in the frame body 110 , for example, the light emitting component 120 is fixed on the bottom 116 of the frame body 110 for emitting light. The frame body 110 has at least one reflective surface (not shown), which can be located on the bottom 116 and / or the inner side 114 of the frame body 110 for reflecting the light emitted by the ligh...

Abstract

The packaging structure includes a frame, at least a luminescence subassembly and a lens. The frame possesses an opening, a medial surface and a base. Being located inside the frame, the luminescence subassembly is in use for sending out light beam. Being positioned above the luminescence subassembly, the lens possesses a surface and at least a groove. The said surface is back on to the luminescence subassembly; and being located on the surface, the groove faces to the luminescence subassembly.

Description

technical field [0001] The invention relates to a packaging structure of a light-emitting component, in particular to a packaging structure of a light-emitting component with a lens, and the lens has a groove to make the light with strong directivity of the light-emitting component produce total reflection. Background technique [0002] With the advancement of electronic technology, especially the prevalence of portable electronic products in daily life, the demand for thin, light, small and low power consumption displays is increasing day by day. Liquid crystal display (Liquid Crystal Display; LCD) is often used in such electronic products due to its advantages of low power consumption, low heat generation, light weight, and non-luminous display, and has even gradually replaced traditional cathodes. Ray tube monitor. [0003] As shown in FIG. 1 , it shows the structure of a conventional liquid crystal display. Generally speaking, the liquid crystal display 2 includes a li...
