New description: [New technical field] This is a kind of LE:D illuminating device, especially an LED illuminating device structure with the effect of widening the angle of opening of the light-emitting cover and the cost-saving effect. . [Prior Art] With the continuous development and advancement of technology, the electronic products and electronic components are becoming more and more gradual toward the trend of lightness, thinness and shortness. The aforementioned electronic components, for example, are made of $diodes (LEDs) because of their volume. Small, money, fast response rate, long life and Wei and so on, so it is gradually being built on lighting equipment. In the early stage of development, the frequency-emitting diode has faced the dilemma of insufficient brightness. In recent years, Na and Lin's breakthrough, the luminous efficiency of the LED 2 has been greatly improved and improved, even comparable to traditional lighting. (10)% of the degree, so it has gradually replaced the current trend of equipment. ▲ As shown in FIG. 1 , a schematic diagram of a conventional LED light-emitting device is shown; a LED light-emitting device includes a light-transmissive cover 5 〇, and a led module μ is placed in the light-transmitting cover 50, wherein the transparent cover 50 is The reticle 50 is a convex lens having a light-emitting surface 501 and an arc-shaped light-incident region 5〇3. The light-incident region 503 is recessed at a central position of the light-transmitting cover 5〇 and has an entrance. The light surface 5031 is formed on a side corresponding to the module (10), so that the light of the light source emitted by the module (10) is refracted through the light incident surface 5〇31 and the light continues to penetrate the light exit surface 501. Projected to the outside to gather together to achieve the effect of concentrating light. However, there are two problems: the first problem is that the thickness of the light transmissive cover 3 M409372 50 is very thick (such as 26 mm), so that the overall thickness of the LED light-emitting device cannot be reduced, and the volume is also quite large. It is easy to cause manufacturing to be difficult or unsuitable for mass production, and there is bound to be an increase in cost. In addition, because the thickness of the transparent cover is too thick, the light loss is increased; the second problem is due to the light entrance surface. The distance between the 5〇31 and the LEDs 53 is too far, that is, the height between the light incident surface 5031 and the opposite LED module 53 is too high, so that the light emitted by the LED module 53 from the light source is projected to the light incident surface 5〇31. When refracting, it is impossible to evenly illuminate the ray tree mask, and further, the thief of the light-transmitting cover 5G (four) light source is subjected to _, so that the brightness of the overall light source cannot be uniform. As described above, the prior art has the following disadvantages: 1. The thickness of the translucent cover cannot be reduced, so that the cost is increased, 2. The uniformity of the light output is not good; 3. The opening angle of the light source of the translucent cover is not wide. [New content] ” In this case, the shortcomings of the above-mentioned technology are identified, and the main purpose is as follows: =1, for a better initial uniformity
