Even-lighting variable-color light source with low power consumption

Abstract

The invention discloses an even-lighting variable-color light source with low power consumption. The light source comprises a control circuit board. A plurality of LEDs are disposed on the control circuit board and are at least in two colors. The LEDs different in color are arranged at intervals. Reflecting film is arranged between the control circuit board and the LEDs. A diffusion plate is disposed above the LEDs. Semitransparent light guide film is disposed on the diffusion plate. The LEDs are symmetrically disposed at two ends of the diffusion plate. The LEDs different in color are disposed on the control circuit board and are synchronously turned on under circuit control, so that a light guide plate can change in various colors with no need for change of the light guide film. The LEDs different in color are arranged at intervals, so that light from the light source is even. The LEDs are also symmetrically distributed at two ends of the diffusion plate and are installed end to end to allow light to mutually irradiate, so that the light can be concentrated to the diffusion plate.

Description

[0001] technical field [0002] The invention relates to a color-changing light source. Background technique [0003] At present, there are many products using LED as the light source on the market. The circular single-color indicator lights are the most, and they are all small in size. There are only one or a few in-line LED beads in the light. If you want to change the color, most of them need to be replaced. Different colors of light guide plates are used, and it is extremely inconvenient to replace the light guide plate in some places. In addition, this kind of light emits unevenly, some places are bright, some places are dark, and the lamp beads inside can be vaguely seen from the outside, because of this These light sources are installed vertically with the control circuit board to install LED lamp beads, so these products cannot effectively and evenly distribute the LED light source on the baffle, which is not beautiful, has no grade, is dazzling, and has a small area...
