FIG. 2 is a schematic forward view of the present invention;
in the figure: 1-a diffusion plate; 2-a circuit board; 3-a lamp cover; 4-a light guide plate; 5-a light input face; 6-light output face; 7-LED light emitting devices; 8-a reflective film; 100-wire.
Detailed Description
As shown in fig. 1-2, the light source of the LED lamp for the cosmetic mirror of the automotive interior sun visor includes a light guide plate 4 and an LED light emitting device 7; the local surface of the light guide plate is covered with a reflective film 8, and the local surface of the light guide plate which is not covered with the reflective film forms a light input surface 5 and a light output surface 6 of the light guide plate; the LED light-emitting device is adjacent to the light input surface of the light guide plate, and light of the LED light-emitting device enters the light guide plate from the light input surface and is output from the light output surface.
The light guide plate is a rectangular plate; the light input surface of the light guide plate is positioned at the side edge of the rectangular plate; the light output surface of the light guide plate is positioned on the top surface of the rectangular plate.
The light guide plate is a long rectangular plate; the light input surface of the light guide plate is located at the short edge of one side of the long rectangular plate.
The light guide plate is characterized in that the surface of the light guide plate, which does not belong to the light input surface and does not belong to the light output surface, is coated with a reflective film capable of reflecting emergent light on the surface of the light guide plate.
The LED lamp also comprises a light-permeable lamp cover 3; the light transmitting part of the lamp cover is positioned above the light output surface of the light guide plate.
The light-transmitting part of the lamp cover is a diffusion plate 1 which can diffuse incident light; the emergent light of the light guide plate passes through the diffusion plate of the lamp cover and then is emitted in a divergent mode.
A circuit board 2 is arranged below the bottom surface of the rectangular light guide plate; the light emitting part of the LED light emitting device is erected on one side of the circuit board and is closely adjacent to the side edge of the light guide plate.
