Environmental protection, pollution-free, anti-seismic and anti-pressure, lamps can be miniaturized, etc. 'LEDs as light source lighting devices are currently widely used in various lighting, such as indoor lighting, outdoor lighting, portable lighting (such as flashlights), situational lighting, etc. In the application. However, since the LED itself is a point light source and the illuminating characteristics have strong directivity, the illuminating angle is much smaller than that of a conventional light source (such as an incandescent lamp 'energy saving lamp, etc.). Referring to Figure 1, the conventional light source (incandescent lamp) has a light divergence angle of SI and S1 is about 160 degrees. Referring to Figure 2, the light divergence angle of an ordinary LED bulb is S2, and S2 is about 60 degrees. Since the effective illumination range of the LED lighting device is much smaller than that of the conventional light source, the application of the conventional light source does not match the light source characteristics required by the original lighting design, so that the LED lighting device cannot directly replace the conventional light source. [00〇3] Referring to FIG. 3, in order to improve the problem that the light divergence angle of the LED illumination device is insufficient, the plurality of LED light source substrates 10 can be joined into a ring-shaped illumination module, which can greatly enhance the LED illumination device. The light divergence angle, but the joining of the plurality of light source substrates 10 makes the electrical connection complicated, and the bonding between the light source substrates 10 causes the heat energy (indicated by arrows) generated by the LEDs 11 to be effectively discharged naturally, so this method is mostly applied to Low luminous flux (low 09814225# single number A0101 page 4 / total 28 pages 1013293856-0 1379965 101 years. August 01, the replacement of page power (low heat) lighting products, there are some applications with efficient The heat sink forms a high luminous flux LED lighting device, but in the application of high luminous flux products, it is required to join a plurality of LED light source substrates and an efficient heat sink at the same time, so that the cost is greatly improved. [0004] In view of this, a The LED lighting device has a wide light divergence angle and a high luminous flux, and has good heat dissipation. [0005] An LED lighting device includes: a first lighting module, a first light source substrate and a first LED light source mounted on the first light source substrate; a second lighting module including a second light source substrate and a second LED light source and a wedge-shaped light guide mounted on the second light source substrate And the reflector, the wedge-shaped light guide is located between the second LED light source and the reflector, and the forward-emitting light of the second LED light source is deflected by the refraction of the wedge-shaped light guide body and the reflection of the reflector to turn into the lateral outgoing light. And a module connecting mechanism connecting the first lighting module and the second lighting module; wherein the first light source substrate and the second light source substrate are parallel to each other and are disposed not to overlap each other in a direction parallel to the light source substrate. The first light source substrate and the second light source substrate are disposed parallel to each other and do not overlap each other in a direction parallel to the light source substrate, and heat generated by the LED light source on the light source substrate does not accumulate, and heat dissipation is good. The outgoing light is converted into lateral outgoing light, thereby expanding the light emission angle of the illumination device.

August 01 The replacement module 30 replaces the connection mechanism 40 and the power input interface 50. The illumination module 20 includes a light source substrate 21 and a lamp cover 22. The light source substrate 21 is mounted on the module connection mechanism 40, and the lamp cover 22 is mounted on the light source substrate 21, and the lamp cover 22 and the light source substrate 21 constitute a casing. The LED light source 23 is located on the casing and mounted on the light source substrate 21. [0009] The second lighting module 30 includes a light source substrate 31, a wedge-shaped light guide body 32, and a reflection cover 33. The light source substrate 31 is mounted on the module connection mechanism 4A. One end of the reflector 33 is mounted on the light source substrate 31 near the module connecting mechanism 4, and extends in a direction away from the light source substrate 31. The wedge-shaped light guide body 32 is mounted between the light source | the substrate 31 and the reflection cover 33. The light source substrate 31, the wedge-shaped light guide body 32, and the reflection cover 33 constitute a casing. The LED light source 34 is located in the housing and is mounted on the light source substrate 31. In the present embodiment, the LED light sources 23' 34 are disposed in the same direction. [0010] The light source tomb 21 and the light source substrate 31 are parallel to each other, are disposed not to overlap each other in a direction parallel to the light source substrate, and are spaced apart from each other in a direction perpendicular to the light source substrate. Referring to Fig. 5' together, in the present embodiment, the light source substrate 21 and the light source substrate 31 are divided by a single light source substrate. Please refer to Figure 6. This LED light source setting method can reduce the cost of the LED substrate and at the same time improve the heat dissipation caused by the multiple light source substrates in the prior art. [0011] Referring to FIG. 7, the first lighting module 20 is illuminating in the forward direction. Referring to FIG. 8, the second illumination wedge group 30 is provided with a wedge-shaped light guide body 32 and a reflection cover 33.

Please refer to FIG. 9 and FIG. 10 , which are respectively a light distribution graph and an illumination characteristic diagram of the first embodiment of the present invention. Please refer to FIG. 11 , which is an illumination characteristic diagram of a general LED lighting device. It can be seen that the LED lighting device of the first embodiment of the present invention can simultaneously illuminate two different directions (e.g., ceiling and ground), thereby obtaining a larger illumination range than a conventional LED lighting device. Referring to FIG. 12, an LED lighting device according to a second embodiment of the present invention is disclosed. Compared with the LED lighting device of the first embodiment of the present invention, the second lighting module 70 is reversely disposed, so that the LED light source of the first light source module (9) and the second light source module 63 of the first lighting module (9) 74 are set opposite each other. Please refer to FIG. 13 and FIG. 14 respectively, which are respectively a light distribution graph and an illumination characteristic diagram of the LED illumination device according to the second embodiment of the present invention. The first illumination module 60 and the second illumination module 70 of the LED illumination device are illuminated. In the same direction but the angle of illumination is different, so that the LED lighting device as a whole obtains a larger illumination range. [0013] Referring to FIG. 15, different lighting effects can be obtained by changing the lampshade of the first lighting module 20. The 'shade 22a' is an ordinary lampshade having a flat surface. The lampshade 22b is a lampshade having an optically convex structure which can condense light to cause the light from the lampshade 22c to be more concentrated to increase the illumination brightness. The lamp cover 22c is a lamp cover having an optical recess structure, which can function as a scatter to cause light to be emitted from the lamp cover 22c to be more dispersed to soften the light. The lamp cover 22d is a lamp cover to which diffusing particles are added, which can provide a light scattering effect and soften the light. The lamp cover 22e is a lamp cover which is provided with a roughness on the surface which can provide a light diffusion effect and homogenize the light. The lamp cover 22f is a lamp cover provided with a light refraction mechanism on the surface, which can change the direction in which light is emitted. 09814225#单号A0]01 Page 7 of 28 Page 1013293856-0 1379965 [0014] [0016] [0019] [0020] [0020] [0023] [0023] [0025] [0025] 101.
