Novel integrated LED (light-emitting diode) headlight

Abstract

The invention discloses an integrated LED (light-emitting diode) headlight, mainly aiming at solving the problems that the conventional motor vehicle headlight is low in illumination color rendering index, the color temperature is difficult to change, the light efficiency is low, the service life is short, energy conservation and environment friendliness is not facilitated, or the LED headlight in the prior art is insufficient in light flux, a heat radiating effect is poor and the like. The integrated LED headlight comprises a light source, a light reflection cup and a transparent face mask; the transparent face mask covers an outlet of the light reflection cup; the light source is arranged in the light reflection cup; an integrated LED lamp core is used as the light source and is of a hollow structure; the inner cavity of the integrated LED lamp core is provided with a baffle plate; the baffle plate separates the inner cavity of the integrated LED lamp core into a high-temperature cooling chamber and a low-temperature cooling chamber which are communicated with each other; the back of the light reflection cup is provided with a heat radiator; one end of the heat radiator is connected with the high-temperature cooling chamber, and the other end of the heat radiator is connected with the low-temperature cooling chamber; and the inner cavity of the integrated LED lamp core and the inner cavity of the hollow heat radiating part are filled with cooling liquids.

Description

Technical field: [0001] The invention relates to the technical field of lamps, in particular to a motor vehicle front lighting lamp which uses high-density integrated light-emitting diodes as a light source, referred to as a headlight for short. Background technique: [0002] High-density strong-light lamps can be used for searchlights, motor vehicle headlights, and night lights for streets, roads and bridges. At present, when making high-density strong-light motor vehicle headlights, filaments or xenon lamps are often used as light sources for lamps. , these motor vehicle headlights that use filament or xenon as the light source have good light density and are conducive to the characteristics of concentrating light for a long time, but their color rendering index is low, generally only 35-50 color rendering index, And the color temperature is fixed with the luminous material and cannot be changed. For example, the filament material can only emit orange-red light with a colo...
