Description of the invention: j [Technical Field of the Invention] The present invention relates to an illumination device, and more particularly to a road illumination device having an anti-glare function. [Prior Art] Glare as a light hazard generally includes direct glare and indirect glare. Direct glare refers to the direct stimulation of the eye from light from a glare source/illuminator with high or no obscuration in the field of view. The glare source illuminator is in the same or adjacent direction of the object being viewed. Indirect glare is the glare produced by a glare source in a non-observing direction, usually caused by reflected light from a highly smooth surface. As shown in FIG. i, when the light source 101 is positioned above the human eye 102, the vertical direction of the human eyelid 2 is deflected within a range of 45 degrees to 85 degrees. The light source 1〇1 directly causes the human eye 1〇2. Glare. ^ As shown in FIG. 2, the light emitted by the street lamp 201 is directed toward the road surface as its own center. In the prior art, the radiation range of the street lamp 2〇1 in the χ direction of the vehicle is greater than the γ direction perpendicular to the X direction. The range of radiation to effectively improve the light utilization of the road, 201. However, the radiation range formed by the street lamp 2〇1 in the x-direction is symmetrically distributed around the street lamp 201, that is, the street lamp 2〇1 is equal to the radiation angles Θ1 and Θ2 on both sides of the street lamp 2〇1, usually θ1=02= 7 〇 , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , The half-gain angle of the money--that is, the luminous intensity emitted by the light is 50% of the maximum hairiness on the plane = the angle between the line and the vertical line. Here, see the light distribution of the street light muscle shown in Figure 3. Line, the light intensity of the light corresponding to the light in the figure is 2〇1 of the street light in the twist to 9〇, 50% of the intensity of the light 'B point corresponds to the light intensity of the light for the street light 2 () 1 in ^ degrees The maximum light intensity to the 90 degree command 'the radiation angle of the street lamp 201 is approximately equal to 7 degrees. It can be seen that the existing street lighting device still causes direct glare to the driver's eyes. Therefore, it is necessary to provide an anti-glare function.

Xiao Da's light emitted by the road lighting device and the road surface are sandwiched by 4; Less than or equal to +30 degrees, so that the solar cell ml wrapped in the light-transmissive package is not directly converted into electric energy and the electric leg is stored in the power-age device. , the device provides power to the light-emitting diode for road lighting It is used to make the road lighting device have the effect of energy saving and environmental protection. 实施 [Embodiment] The following is a detailed description of the present invention in combination with the following: 1 using 4' the road surface provided by the first embodiment of the present invention Illumination device 10, illuminating: month, device 10 includes a light source 12, a slap 3, a solar cell 14, and a light transmissive package 15. The light source 12 includes a light emitting diode 121 and an optical element 122. The body 12 is a white light emitting diode or a high power light emitting diode, and other light emitting diodes that can emit different colors of light, such as:,,, first, i, etc. emit lightly with the light emitting diode 121 That is, the front line of the light-emitting diode 121 directly enters the optical element (2), and is emitted through the optical device of the optical element 122 for 201100720. In this embodiment, the light source 12 is disposed on the path φ η, and the light emitted by the LED 201 is emitted upward into the optical element 122. The optical element 122 is used to deflect the light emitted by the light-emitting diode 121. The light source 12 is laterally emitted and extends along the extending direction X of the road surface η. Each of the light elements 122 has a longitudinal axis (i〇ngitU(jinai axis)i22. The optical element 122 includes a funnel-shaped top surface 1221 and a vertical side wall 1222. The light emitting diode 121 is disposed at the bottom of the optical element 122. The geometric center is opposite to the top surface 1221. The surface 1221 is a quadric surface, and in the embodiment A, the top surface 1221 is a parabolic surface. The light emitted from the LED 112 is mainly directed to the top surface 1221. Total internal reflection (TIR) occurs at the top surface 1221 and exits through the vertical sidewall 1222 at an angle of almost 90 degrees to the longitudinal axis 1220. Light rays that are directed from the LEDs 121 directly toward the vertical sidewalls 1222 deviate. The vertical direction of the vertical axis 122〇 is emitted through the vertical side wall 1222. Therefore, the light emitted through the optical element 122 may deviate from the extending direction of the road surface 11 by a slight angle, that is, between the light emitted through the optical element 122 and the road surface 11. The angle 0 is within a predetermined range, for example: _3 S S Θ $+30 degrees, where the angle 0 means that the illuminating intensity emitted through the optical element 122 is 5 〇% of the maximum luminous intensity on the plane. In addition, a reflective layer 1223 can be disposed on the top surface 1221 of the learning element 122 to increase the south reflection efficiency. The 力t force storage device 13, such as a battery, is connected to the light emitting diode 121. The power storage device I3 is used for storing electrical energy and is capable of supplying power to the light-emitting diode 19, and the 〇古拉 14 is electrically connected to the power storage device 13 for converting the solar light into electricity 9 and power The scale is in the electric bribe device 1; 3 towel, which is conducive to the night power storage county set 13 to provide power to the light-emitting diode 121 for use as a pavement u Zhaoming. 14 package through two ====== 6 201100720 ^ page cone The profile has a side 151 and a side surrounding the top surface 151.

The structure of the optical element included in the light source 12 in the jf 3 J 2 embodiment is not limited to the design so that the light source 12 emits a relationship between the pros and the road surface 11 ' hereinafter will be exemplified by several different optical elements. 5. A light source 32 comprising a private shackle. m ί学_Optical component^Optical 1 piece 322-:i;: ^ 322f 3221 ί L 'The slope of the top surface 3221 is from the inside to the outside and the side surface 3222 is a flat π curved surface. The light emitted from the light-emitting diode 321 is totally reflected from the a 3221' on the top surface 3221 and is several times out of the vertical axis. The light emitted from the light-emitting diode 321 directly toward the vertical side _ 7 201100720 is emitted at an angle of almost 90 degrees. Therefore, the exit portion of the optical element 322 is parallel to the extending direction of the road surface 11 , and a small portion deviates from the road surface 11 by the angle of light, that is, the light emitted through the optical element 322 and the road surface 11 , and the refresh angle θ is within a predetermined range. For example: _25 degrees ^ θ $+25 degrees, in the second day f is the angle of the light emitted by the * element 122 on the next day is the angle between the light of the 50% of the most 'intensity on the plane and the road surface u. In addition, a reflective layer 3223 may be disposed on the top surface 3221 of the optical element 322 to further improve the reflection efficiency. Referring to the figure, a light source 42 includes a light emitting diode 421, an optical element 422 that is lightly coupled to the light emitting diode 42U. The optical element 422 is a & axis Ο 。 . Optical element 422 includes a bottom portion 4221 and a top portion 4222. The bottom portion 4221 has a recess 4223 for receiving the light emitting diode 421 at a central position. The outer surface 4224 of the bottom = 21 is a smooth curved surface. The top portion 4222 includes a funnel-shaped conical top surface 4225 and a vertical side wall 4226. The light emitted from the LED 421 enters the optical element 422 via the bottom surface and the side surface of the depression 4223, and most of the line entering the bottom portion 4221 will pass through the outer surface 4224 at an angle of almost 9 degrees to the longitudinal axis 422〇. Light that is 'out' and is reflected by the outer surface 4224 will enter the top 4222 or be reflected again = exit through the outer surface 4224. Light entering the top portion 4222 is reflected by the top surface 4225 and exits through the vertical sidewalls 4226 at an angle of approximately 90 degrees to the longitudinal axis 4220. Therefore, most of the light emitted through the optical element 422 is parallel to the road surface u, and the direction of extension, a small portion will deviate from the direction in which the road surface u extends, that is, the angle between the light emitted through the optical element 422 and the road surface 11. 0 is in a predetermined range =, for example, -25 degrees g0g + 25 degrees, where the angle p refers to the angle between the light emitted by the optical element 422 and the light intensity of the maximum luminous intensity of 5% by the plane and the road surface 11 . In addition, a reflective layer 4227 may be disposed on the conical top surface 4225 of the top portion 4222 to further improve reflection efficiency.

The light-transmissive step # is enough to insert into the road surface U to place the solar battery 14 at the bottom of the dome structure to obtain the correction. The road lighting device provided by the om mrnml 40 5 is the battery of the second embodiment (10) Petal Sun = In this detail, the gamma 2 and the solar power 1 surface i1 are enough for the space of the lighting device 40. /, using the substrate 46', the road illumination device 5 provided by the fifth embodiment of the invention is provided, and the surface of the solar device 50 is opposite to the side of the second embodiment.
