Problems solved by technology

However, in order to realize various lighting patterns, a structure other than the light source is required, which leads to an increase in the size of the lamp, a decrease in brightness, etc.
Therefore, various realizations of lighting patterns of lamps are limited

Abstract

The present invention provides a lamp comprising: a half mirror having a top surface and a bottom surface, reflecting a portion of light incident onto the bottom surface, and emitting another portion of the light to the outside; a reflective layer disposed at the lower side of the half mirror and disposed to face the bottom surface of the half mirror; an electrochromic layer disposed between the half mirror and the reflective layer and disposed to cover the reflective layer; a light source unit emitting light between the half mirror and the reflective layer; and a control unit applying a current or a voltage to the electrochromic layer, wherein the electrochromic layer has a variable light transmittance as the current or voltage is applied thereto.

Description

technical field [0001] The present disclosure relates to a vehicle lamp or a car lamp and a control method thereof, and more particularly, to a vehicle lamp using a semiconductor light emitting device. Background technique [0002] Vehicles or automobiles are equipped with various lamps having lighting functions and signaling functions. In general, a halogen lamp or a gas discharge lamp is generally used, but in recent years, a light emitting diode (LED) has attracted attention as a light source for a vehicle lamp. [0003] LEDs can increase the freedom of lamp design by minimizing their size, and exhibit economic benefits due to the advantage of semi-permanent life, but most LEDs are currently produced in packages. LEDs themselves other than packages are being developed as semiconductor light emitting devices that convert electric current into light, ie, image display light sources equipped in electronic devices such as information communication devices. [0004] In recen...
