Problems solved by technology

[0004] The above-mentioned conventional diode light sources all have the following disadvantages: the external electro-optical conversion efficiency of the light-emitting diode is 30-40%, the white light luminous efficiency is 120-170lm / W, and the light efficiency is low
However, the packaging structure of this light-emitting diode light source emits light from one side and has side-lighting dead angles, which cannot meet the needs of four-sided light-emitting lighting fixtures without dead angles, and the phosphors and light-emitting diodes are not completely sealed in the substrate, which is unsafe. Hidden danger

Embodiment 1

[0029] Reference Figure 2 to Figure 4 . A light-emitting diode light source structure, comprising a rectangular parallelepiped package body 1 composed of a light-transmitting substrate 11, a light-emitting diode device, and a light-transmitting top plate 13. The light-emitting diode device is fixedly packaged on the opposite surface of the light-transmitting substrate 11 and the light-transmitting top plate 13. Between; The package body 1 is a long strip structure, and its two longitudinal sides are correspondingly fixed and attached to the transparent side plate 2.

[0030] Reference Figure 2 to Figure 4 . The light-transmitting substrate 11 and the light-transmitting top plate 13 are rectangular transparent sheets of equal specifications. The light-transmitting substrate 11 and the light-transmitting top plate 13 respectively include a first transparent sheet 101 and a second transparent sheet 103 that are fixedly stacked together, and the opposite surfaces of the first tran...

Embodiment 2

[0040] The difference between this embodiment and the first embodiment above is: reference Image 6 with Figure 7 . The positive and negative light-emitting electrode sheets 122, 123 are spaced at the edge of the same width side of the light-transmitting substrate 11, and the positive and negative connecting electrodes 125, 126 extend from the width side of the package body 1; preferably, positive and negative light-emitting The electrode sheets 122 and 123 are fixedly glued to the transparent substrate 11 and the transparent top plate 13 by insulating glue. The light-transmitting side plate 2'is also fixed and pasted on the other width side of the package body 1. The two longitudinal sides of the package body 1 are packaged with light-transmitting side plates 2, and the other width side of the package body 1 is also packaged with a light-transmitting side plate 2'. The structure of the light-transmitting side plate 2'is the same as the above-mentioned translucent side board. ...
