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 characterized by comprising: a half mirror which is provided with a top surface and a bottom surface, and which reflects a portion of light incident on the bottom surface and discharges another portion of the light to the outside; a reflection layer disposed facing the bottom surface of the half mirror; light guides which are disposed between the half mirror and the reflection layer, and each of which is provided with one end and the other end and totally reflects a portion of light incident on the one end and discharges the light to the outside through the other end; and a plurality of light sources, each of which emits light, wherein the one end overlaps with the light source so that the light emitted from the light source is incident on the one end, and the other end of the light guide passes through the half mirror.

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...
