There are also many places where LEDs are used as lighting fixtures. However, due to the existing LED packaging problems, the light emitted by the LEDs is glare, which does not meet the visual requirements of today's people, and its light is dim, mostly used as decorative lights. . For example, the double-shell non-glare bulb with patent number 96225173.9 has two layers of shells on the outside of the lamp cap, and the inner shell shell scatters light to make it bright and soft, but the structure of the inner shell of the structure is the same. It is very troublesome, and it adopts a filament-type incandescent bulb, which consumes a large amount of electricity and has high heat. The outer casing is a vitreous body and is easily damaged. Another example is an LED analog decorative lamp with the patent number 03247942.5, which is mounted on the analog illuminator. On the board, the analog illuminating board has a blind hole similar to the shape of the LED lamp. This method is cumbersome to make, especially the process of simulating the illuminating board is cumbersome, and the light of the lamp is only soft but not bright, nor can it be It plays a role in lighting; although the above-mentioned several schemes using LEDs solve the problem of LED glare, the light is dim and not bright, and cannot be used for illumination.

参照图 1和图 2， 在导光板 3的一面布设纹理， 如图 6中， 31为 带丝印纹理的导光板， 32为带磨砂紋理的导光板， 33为带凹凸状纹 理的导光板； 再在导光板 3的带紋理面覆盖一层反光层 4， 然后在导 光板 4的另一面， 即不带紋理面覆盖一层散光层 2， 将带有 LED6的 电路板 5放置在导光板 3的边缘处， 与导光板 3靠近； 在铝基板 8的 一面涂上导热胶 7， 再把涂好导热胶 7的铝基板 8插入到边框 1的凹 槽内， 将边框 1套上电路板 5后， 再套在散光层 2、 导光板 3和反光 层 4上， 使电路板处在边框 1的凹槽内， 与铝基板 8不带导热胶 7的 一面相贴， 而散光层 2、 导光板 3和反光层 4被边框 1夹紧； 电路板 5与边框 1间还有两块弹片 9，使边框 1内的组件不会在凹槽内滑动， 最后用螺钉将相邻的边框紧固。安装好后如图 1所示， 其内部结构如 图 3所示。电路板 5及 LED6不仅可以设置于导光板 3的两对边边缘， 也可以设置于导光板 3的两邻边边缘，还可以在导光板 3的三边或四 边边缘都设置电路板 5和 LED6。 Referring to FIG. 1 and FIG. 2, a texture is arranged on one side of the light guide plate 3, as shown in FIG. 6, 31 is a light guide plate with a silk screen texture, 32 is a light guide plate with a matte texture, and 33 is a light guide plate with a concave-convex texture; The light-reflecting layer 4 is covered on the textured surface of the light guide plate 3, and then the astigmatism layer 2 is covered on the other side of the light guide plate 4, that is, the uncoated surface, and the circuit board 5 with the LED 6 is placed on the light guide plate 3. At the edge, close to the light guide plate 3; on one side of the aluminum substrate 8, a thermal conductive adhesive 7 is applied, and then the aluminum substrate 8 coated with the thermal conductive adhesive 7 is inserted into the groove of the frame 1, and the frame 1 is placed on the circuit board 5 , and then placed on the astigmatism layer 2, the light guide plate 3 and the light reflecting layer 4, so that the circuit board is in the groove of the frame 1 and is attached to the side of the aluminum substrate 8 without the thermal conductive adhesive 7, and the astigmatism layer 2 and the light guide plate 3 and the reflective layer 4 are clamped by the frame 1; there are two elastic pieces 9 between the circuit board 5 and the frame 1, so that the components in the frame 1 do not slide in the groove, and finally the adjacent frames are fastened by screws. After installation, as shown in Figure 1, its internal structure is shown in Figure 3. The circuit board 5 and the LED 6 can be disposed not only on the two opposite edge edges of the light guide plate 3, but also on the two adjacent edge edges of the light guide plate 3, and the circuit board 5 and the LED 6 can be disposed on the three or four edges of the light guide plate 3. .
光线在散光层 2、 导光板 3和反射层 4之间的传播路径如图 4， 当通电后 LED发光， 光线经导光板 3的紋理面 10反射和折射， 折射

When the LED is energized, the LED emits light, and the light is reflected and refracted by the textured surface 10 of the light guide plate 3, and is refracted. The light is then reflected by the reflective layer 4, refracted by the light guide plate 3 and then refracted by the astigmatism layer 2, and emitted from the surface of the astigmatism layer 2; the light reflected by the texture on the light guide plate 3 passes through the light guide plate 3, and then scatters through the astigmatism layer 2 , emitted from the surface of the astigmatism layer 2. The light emitted in this way has a low color temperature, no glare, soft feeling, and no glare. Thanks to the high power LED of 1W, the light is very bright and can be used for illumination. The heat conductive insulating solid 7 can conduct the heat emitted by the circuit board 5 to the frame 1 and the frame 1 can be made of a heat conductive hard material to accelerate the heat dissipation speed.
