Abstract

The invention relates to a color-mixed LED device, and belongs to the technical field of LED packaging, and the LED device comprises a housing which is used as a reflecting layer and a substrate; at least one light-emitting element which is mounted on the inner surface of the housing; and a dodging element which is arranged in the housing and is used for dodging and serving as a light emitting surface.

Description

technical field [0001] The present disclosure relates to the field of LEDs, specifically to the technical field of LED packaging, and more specifically to a color-mixing LED device. Background technique [0002] With the rapid development of LED-related technologies, LED light sources have been widely used in daily life, industrial production, and scientific research. LED is an electroluminescent solid-state light source. Compared with traditional light sources, LED has the advantages of environmental protection, long life, and high efficiency. [0003] In particular, its adjustable spectral characteristics and convenient dimming methods provide infinite possibilities to meet people's needs for high light color quality and diversification of light sources, and these needs often need to be realized with the help of multi-channel LED light sources. [0004] One of the commonly used methods is to use short-wavelength LEDs to excite long-wavelength phosphors to obtain a spectru...
