Z5 revision correction & page 5, new description: [New technical field] [0001] This creation is about a uniform light side LED light-emitting device, especially to eliminate the periphery Bright side LED light emitting device. [Prior Art] [00〇2] In the illumination device (including the general luminaire and the backlight module for LCD) in which the LED is placed on the side, the side of the light-emitting surface close to the LED illuminating member tends to produce a bright line. The phenomenon is similar to the so-called hot spots in general edge-lit LED backlight modules. This represents the optical quality of a high-quality optical illumination device. When the size of these edge-lit LED lighting devices is larger, the thinner the thickness, the more obvious this phenomenon. 'We are at ―" in our previous case (US Patent No. 7891840, Republic of China Patent No. 1352180, Republic of China Patent Publication No. 2 〇 1201344, and US Patent Application No. 201 1 0267839, etc.) In the cavity, an optical mechanism such as a narrow beam LED, a symmetrical convex structure with at least one small inclination angle on the reflective substrate, and a diffusion plate/reverse prism layer can be used to design a uniform light-emitting side-light LED uniform surface. The light source, to a certain extent, can avoid the occurrence of bright bands. However, under the trend of large-scale and thin-film technology, the bright band problem and the accompanying illuminance and the deterioration of the brightness uniformity are bound to be technically The challenge that cannot be avoided. 1013240268-0 M437971 [0005] [0007] [0008] [0009] On June 25, 101, the modified replacement page is set on a frame (F) 'the reflector (A) and A reflector (C) is disposed on each side of the diffuser plate (B), and an LED light-emitting member (D) is disposed in the reflector (C). When the LED light-emitting member (D) emits light, part of the light is directed toward the reflector (c) ), when the light is reflected by the reflector (c), The relationship of the large-angle reflection will be directly scattered from the position of the diffuser (B) near the reflector (c.). Due to this phenomenon, the light-emitting surface scattered by the diffuser (B) is close to the reflector (C). a bright band (e) is formed on the side of the film. The following patent has proposed a technique for eliminating the bright band of the edge-light type illuminating device. In the Republic of China Invention Patent Announcement No. 5 6 9 06 7 "Backlight mode for eliminating edge bright lines" In the group and the method j, the light guide plate is disposed at least one of the light absorbing unit or the light shielding unit in the vicinity of at least a part of the edge of the light guide plate to weaken the light intensity of the light guide plate that is not totally reflected. In the "Surface light source device of side light type" of US Pat. No. 6,074,070, a light blocking member l8 is provided near the opening of the reflector, and the reflectance is lowered by the light blocking meraberl8. In the previous case, whether the light-absorbing unit 'shading unit or light blocking meraberl8 (shading element) was used, the reflectance was reduced by absorbing part of the light to eliminate the bright side of the light-emitting side. However, the disadvantage of light absorption is that the energy utilization rate is low, and the light energy is absorbed to generate thermal energy and cause overheating. 10120422#"single number A0101 Page 4 of 17 1013240268-0 M437971 [New content] ΙΟί年.06月25日核正换页 [0010] [0011]
