LED unit and optical source module having the same

Abstract

The present invention discloses an LED unit, which and an optical source module having the same are provided in a lighting apparatus. The LED unit comprises a first LED array emitting a first irradiation light; and a second LED array lighted up separately from the first LED array or together with a portion of the first LED array and thus emitting a second irradiation light. The invention also discloses an optical source module comprising: an LED unit emitting a first irradiation light or a second irradiation light; a first reflection part reflecting the first irradiation light or the second irradiation light emitted from the LED unit; a light shade part shutting out a portion of the first irradiation light reflected by the first reflection part; a second reflection part reflecting the second irradiation light reflected by the first reflection part; and a lens part transmitting the first irradiation light, passed through the light shade part, or the second irradiation light, reflected by the second reflection part.

Description

technical field [0001] The present invention relates to a light emitting diode (LED) unit, and more particularly to an LED unit provided in a lighting device, and a light source module having the LED unit. Background technique [0002] Generally, lighting devices are provided in automobiles for stably obtaining a driver's field of vision while driving even when the intensity of ambient lighting is low. Among these lighting devices, headlamps are classified into high-beam units and low-beam units according to the irradiation angle and light amount of light irradiated from the lamps. The work of the high beam unit and the low beam unit are respectively controlled by the operation of the multi-function switch on the side of the steering wheel. [0003] In addition, fog lamps are auxiliary lamps for obtaining driver's vision in bad weather such as snow, rain or fog. Fog lights illuminate a closer position than headlights, and emit light with high transmission and high irradiat...

AI Technical Summary

Problems solved by technology

[0006] However, the above-mentioned conventional lighting device requires the DRL provided separately from the headlamp or the fog lamp, and thus additionally requires parts for manufacturing and installing the DRL and its manufacturing process, and requires a separate space for installing the DRL to implement the DRL function in the lighting device , thus restricting the structure and design of the lighting device and the car with the lighting device

[0007] In addition, the cost and time taken to manufacture the lighting device and the car having the lighting device increase, and the total weight of the lighting device and the car having the lighting device increases
