Embodiment Construction

[0018] The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0019] see Figure 4 , a road surface lighting device 10 provided by the first embodiment of the present invention is used to illuminate the road surface 11, the lighting device 10 includes a light source 12, a power storage device 13, a solar cell 14, and a light-transmitting package 15.

[0020] The light source 12 includes a light emitting diode 121 and an optical element 122 .

[0021] The light emitting diode 121 is a white light emitting diode or a high power light emitting diode, of course, it can also be a red light, a blue light or other light emitting diodes that can emit light of different colors.

[0022] The optical element 122 is optically coupled with the light emitting diode 121 , that is, the light emitted by the light emitting diode 121 directly enters the optical element 122 and exits through the optical effect of the o...

Abstract

The invention relates to a road illumination device with a function of preventing glare. The road illumination device comprises a light source, a power storage device, a solar cell and a light transmission package, wherein the light source comprises at least one light-emitting diode and an optical element optically coupled to the at least one light-emitting diode; the optical element is used for deflecting light rays from the at least one light-emitting diode to the side direction of the light source to emerge along the extending direction of the road, and the included angle between light rays from the optical element and the road is more than or equal to -30 degrees, or less than or equal to +30 degrees. The power storage device is electrically connected with the at least one light-emitting diode. The solar cell is electrically connected with the power storage device and used for directly converting sunlight into electric energy and storing the electric energy in the power storage device. The light source and the solar cell are coated in the light transmission package.

Description

technical field [0001] The invention relates to a lighting device, in particular to a road surface lighting device with anti-glare function. Background technique [0002] Glare, as a kind of light pollution, generally includes direct glare and indirect glare. Direct glare refers to the stimulation of the eyes directly by the light from glare sources / luminous objects with high brightness or insufficient shielding in the field of view. Indirect glare refers to the glare produced by the glare source in a non-observing direction, usually caused by the reflected light of a highly smooth surface. Such as figure 1 As shown, when the light source 101 is located above the human eye 102 , the light source 101 will cause direct glare to the human eye 102 within the range of 45° to 85° deflection from the vertical plane 103 where the human eye 102 is located. [0003] Such as figure 2 As shown, the light emitted by the street lamp 201 is projected toward the road with itself as the...
