Embodiment Construction

[0022] The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] see Figure 4 , the lighting device 100 provided by the first embodiment of the present invention is used to illuminate the road surface 11, wherein the extension direction of the road surface is X, and the lighting device 100 includes a light source 12, a power storage device 13, and a solar cell 14 , a light-transmitting encapsulation body 15 .

[0024] The light source 12 includes a light emitting element 121 and an optical element 122 .

[0025] The light emitting element 121 can be a light emitting diode, a light emitting diode chip or other light emitting bodies. The light emitting element 121 may be one or multiple.

[0026] The optical element 122 is optically coupled with the light emitting element 121 , that is, the light emitted by the light emitting element 121 directly enters the optical element 122 and exits through ...

Abstract

The invention relates to an illumination device, which comprises a light source, an electricity storage device, a solar cell and a light-transmitting package. The light source comprises at least one light-emitting diode and an optical element coupled with the at least one light-emitting diode; the optical element is used for deflecting light rays emitted by the at least one light-emitting diode towards the side direction of the light source and making the light rays emergent along the extending direction of the road surface; included angles formed by the light rays emergent by the optical element and the road surface are asymmetrically distributed on the two sides of the road surface; the electricity storage device is electrically connected with the at least one light-emitting diode; the solar cell is electrically connected with the electricity storage device and is used for converting sunlight into electric energy and storing the electric energy in the electricity storage device; and the light source and the solar cell are covered by the light-transmitting package.

Description

technical field [0001] The invention relates to an illuminating device, in particular to an illuminating device with an anti-glare function. Background technique [0002] Light Emitting Diode (LED, Light Emitting Diode) has the advantages of high brightness, low operating voltage, low power consumption, easy matching with integrated circuits, simple driving, and long life, so it can be used as a light source and widely used in the lighting field. For details, please refer to Joseph Bielecki et al. wrote Thermal Considerations for LED Components in an Automotive Lamp in 2007IEEE, 23rd IEEE SEMI-THERM Symposium. [0003] 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,...
