Abstract

The invention discloses a color-temperature-adjustable light source module, which comprises a substrate, a first color temperature light source group, a second color temperature light source group anda third color temperature light source group. The first color temperature light source group, the second color temperature light source group and the third color temperature light source group are packaged on the substrate. The color coordinates of the first color temperature light source group, the second color temperature light source group and the third color temperature light source group aredifferent. The first color temperature light source group and the second color temperature light source group are connected in parallel. The first color temperature light source set comprises a firstcolor temperature light source module and a first resistor module which are connected in series. The voltage of the first color temperature light source module is smaller than that of the second color temperature light source group. According to the invention, the color temperature change track of a light source formed by the plurality of color temperature light source groups can be overlapped with the track of a black body according to the magnitude of the current to form a white light effect.

Description

technical field [0001] The invention relates to the field of optoelectronic technology, in particular to a light source module with adjustable color temperature. Background technique [0002] At present, the adjustable color temperature COB (Chip On Board) light source is generally composed of a group of high color temperature light source and a group of low color temperature light source. When the user needs a high color temperature environment, the high color temperature light source is used; Low color temperature light source, when the user needs a medium color temperature environment, two sets of color temperature light sources are used to work together, and different color temperature effects can be achieved according to the ratio of the two sets of color temperature. [0003] Such as figure 1 As shown, in the prior art, the coordinates of the high color temperature light source is point C" and the coordinates of the low color temperature light source is point A", then...
