Abstract

The invention discloses a color and color temperature control system and method for a lamp. The system comprises a command input device, a main controller, a DA conversion circuit, a multi-path constant current driving device, a multi-path constant current power supply and an RGB dual color temperature lamp module, wherein the RGB dual color temperature lamp module is composed of a plurality of RGB dual color temperature LED lamp beads; the command input device is configured to receive an operation command; the main controller is configured to analyze the operation command, calculate a currentvalue of each LED lamp bead, drive the DA conversion circuit to generate a corresponding current analog quantity according to each current value, and transmit the corresponding current analog quantity to the multi-path constant current driving device; and the multi-path constant current driving device is configured to control the multi-path constant current power supply to output a correspondingcurrent to drive the RGB dual color temperature light module according to the circuit analog quantity. The system can adjust the brightness and color temperature of each LED lamp bead to realize the adjustment and control of the LED lamp module, and the process is simple and easy.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a color and color temperature control system and method of a lamp. Background technique [0002] With the rapid development of science and technology, LED technology has been widely used in people's daily life, such as daily lighting, stage lighting effects, etc. However, the current lamps that can be used for RGB color conversion are generally only used for stage effect color conversion, not as a normal lighting system light source; even if the mixed light becomes white, the color temperature and color rendering are unstable due to low light efficiency, and are not suitable for lighting system light sources use. However, ordinary lighting fixtures do not have the function of changing different colors because they need to output white light with a stable color temperature. Therefore, today's RGB adjustment and dual color temperature adjustment are controlled separa...
