Problems solved by technology

[0004] Regardless of the design concept, it is necessary to use multiple LEDs with different wavelengths to control the light mixing separately. The current light-mixing and color-mixing LED module flat-packs multiple LED chips with different wavelengths on the substrate, and the placement area is large. Large spacing, difficult to achieve uniform light mixing

Abstract

The invention discloses an LED laminated light source module capable of achieving light color adjustment. The light source module comprises a plurality of layers of substrates and a plurality of LED light-emitting chips. A step-shaped through hole is formed in the center of each layer of substrate in the multiple layers of substrates, and a circuit layer is uniformly distributed on the surface of each layer of substrate. Each LED light-emitting chip is manufactured in the step-shaped through hole of the corresponding substrate and electrically connected with the circuit layer on the surface of the corresponding substrate. The LED laminated light source module capable of achieving light color adjustment has the beneficial effects of being adjustable in light color, small in area, even in light emitting, diversified in emitted light color and long in service life and facilitating light mixing.

Description

technical field [0001] The invention relates to an LED light source, in particular to an LED light source which mixes light by controlling a plurality of LED chips with different wavelengths. Background technique [0002] LED (light emitting diode), that is, light-emitting diode, is considered to be the third-generation lighting technology after incandescent lamps and fluorescent lamps in the history of human lighting. It is a new type of high-efficiency solid-state light source with small size, fast response, long life, energy saving, It has obvious advantages such as green and environmental protection, and has been widely used in indoor and outdoor and many special lighting occasions. [0003] The emergence of LED has broken the design methods and ideas of traditional light sources, and two new design concepts have emerged. One is scene lighting: design lamps and lanterns according to the needs of the environment, create a beautiful and gorgeous lighting environment, to e...
