Problems solved by technology

However, shielding 14 reduces light efficiency
[0009] In particular, if image 3 As shown, when the headlight is equipped with a mechanical roller-shaped shield 14a, it will be accompanied by vibration, so looseness and gaps are likely to occur at the joint part, which reduces the service life and causes deformation of the joint structure
And, there is noise

Abstract

The present invention relates to a multi-array LED chip for embodying a cut-off line, and the multi-array LED chip includes: a plurality of LED modules which emits light; and at least one low beam LED module which emits light, in which the LED module and the low beam LED module are disposed to match a cut-off line, and the LED module and the low beam LED module are individually turned on and off such that a low beam is emitted. Accordingly, a direct type of light is emitted, and thus a low beam, which complies with regulations regarding the cut-off line, is embodied, and light efficiency does not deteriorate.

Description

technical field [0001] The present invention relates to a multi-array LED chip, specifically, the multi-array LED chip and headlights of a low beam (low beam) that can comply with cut-off line regulations by using the LED module of the multi-array LED chip to turn on and off. Background technique [0002] Generally speaking, in order to ensure the driver's field of vision when the surrounding illuminance is low, the car is equipped with a lighting device. Among them, the head lamp device is divided into a high beam device and a low beam device according to the difference in the irradiation angle and light quantity of the irradiated light. [0003] As the light source of headlights for automobiles, there are LED headlights using LED (light emitting diode). [0004] Here, LED (light emitting diode) is a diode that releases excess energy as light when injected electrons and holes recombine, and there are red light emitting diodes and green light emitting diodes. Due to its ad...
