LED replacement light source with adjustable color temperature

Abstract

The invention discloses an alternative LED light source with adjustable color temperature, which includes a radiator, a power supply assembly, an LED light source assembly, a light guide column, and a reflective cup. The packaged LED chip assembly consists of a power supply assembly including a control logic circuit and multiple LED drive circuits. Multiple LED drive circuits are connected to LED chips with different color temperatures and can drive LED chips with different color temperatures to turn on or off, so as to realize the adjustment of the lighting color temperature. effect, and due to the mixed welding of LED chips with different color temperatures, when the LED chips of different color temperatures are lit, the angle of light emitted by them remains consistent, that is, when the light source is adjusted for lighting with different color temperatures, the irradiation angle of the light source will not change. The effect that the lighting angle does not change when the color temperature is adjusted does not affect the lighting of the lamp, and the light guide column and reflector cup can also be replaced to meet the needs of different lighting angles.

Description

technical field [0001] The invention relates to an LED light source, in particular to an LED replacement light source with adjustable color temperature. Background technique [0002] Due to its small size, low power consumption, long service life, high brightness, low heat, and environmental protection, LEDs have gradually become popular in daily life. Most of the commonly used LED chips are monochrome chips, which are mostly used as LED light sources. It emits light in a single color. When lighting with different color temperatures such as cool white, warm white, and sunlight, it is necessary to configure LED lamps made of LED chips with different color temperatures. LED chips are usually single-color integrated packages, and there is a large distance between packaged chips with different color temperatures, so that the LED chips with different color temperatures will have inconsistent lighting angles after being scattered by the lens, which will affect the lighting effect ...
