[Embodiment] The technical content and detailed description of the present invention are described in conjunction with the drawings, such as 201100719. Referring to the second figure, a preferred embodiment of the LED street lamp of the present invention is shown. The LED street lamp 2 〇 mainly includes a light pole 21, a lamp holder 22, and a set of light source modules 23. The lamp post 21 is disposed on a road and the lamp holder 22 is disposed on the top end 211 of the lamp post 21. The bottom surface of the socket 22 is recessed upward to form a recess 221 . As shown in the third figure, the light source modules 23 are disposed in the recesses 221 of the socket ◎ 22 and are used to project light downward. Each of the light source modules 23 includes a base 231 coupled to the base 22, and at least one light-emitting diode element 232 disposed on the base 231 is coupled to the base 231 and surrounds the light-emitting diode The reflector 233 of the polar body component 232 and a light transmissive plate 234 disposed on the reflector 233. Preferably, the pedestal 231 can be a flat heat pipe for dissipating heat from the illuminating diode elements 232. Referring to the fourth and fifth figures, the light-transmitting plate 234 is formed with two Fresnel lens portions facing the light-emitting diode element 232 protruding toward the light-emitting diode element 232 (Fresnellens P〇rti〇n) 235. Also, the portions are arranged substantially in a predetermined direction. The predetermined side = the direction in which the ear lens portion 235 is connected. As shown in the sixth figure, each of the Fico lens portions 235 is formed by a plurality of concentric convex rings protruding upward from the light-transmitting plate 234, and each of the convex rings is said to have a connecting inner side 237 and an outer side surface. .

In addition, as shown in the tenth figure, in another embodiment of the light-transmitting plate, the transparent plate 264 can form an elliptical Fresnel lens portion 2, and can also be adjusted to pass through the transparent plate 264. The outwardly projected light distribution generally presents an asymmetric elliptical distribution. 201100719 Alternatively, if the eleventh HI is at - t, the light-transmissive plate 274 can be formed with a jin = light-transmissive plate, and the embodiment can also be adjusted to pass through the transparent J-shaped Philippine lens portion. 275, the light distribution of the rendered-asymmetric Μ outward projection is roughly or 'as shown in the twelfth figure, the material WW π is the more transparent type of the slab - the embossing of the embodiment, the elliptical shape and the upper The pupil distance of five identical apertures is formed, and each of the (four) re-lens portions 255 can have different asymmetry of the light distribution. =隹: 'The Philippine buried lens portion on the same light-transmissive plate can have no = focal length and can also be applied to the second to the tenth--the Philippine buried ear eight: The symmetry of the ray knife projected by the Philip lens portion 255 is more transparent to the optical analog software. 4=:: The opaque plate 254 produced by the Γ _ ear, asymmetric focal length design, such as As shown in Fig. 13, the direction is the vertical Χ direction, and the X direction of the Philippine lenticular lens portion 255 is: the focal length Fy from which the Fx is larger than the Υ direction. Thereby, the light is allowed to pass through the fluorophone portion 255, and the degree of divergence in the X direction is greater than that in the Y direction to improve the asymmetry of the light distribution. It should be noted that the above-mentioned symmetrical focal length design can also be applied to the Fresnel lens portions in the second to eleventh drawings. However, the above is only the preferred embodiment of the present invention and is not intended to limit the scope of the present invention.
