Linear color temperature database construction method, color temperature adjustment method and device, led lamps

Abstract

The invention discloses a linear color temperature database construction method, a color temperature adjustment method and device, and an LED lamp. The color temperature adjustment method is: receiving a DMX control signal from a DMX console, and the DMX control signal has a color temperature channel DM value; according to the color temperature channel DM value And the corresponding brightness DM value is obtained from the linear color temperature database, and the brightness of the LED lamp bead is adjusted according to the brightness DM value. By constructing a linear color temperature database, the present invention can conveniently and quickly select the required color temperature only by adjusting the DM value of the color temperature channel when the color temperature of the scene needs to be changed, thereby satisfying the use requirements of lights in the scene to a greater extent.

Description

technical field [0001] The invention relates to the field of LED lighting, in particular to a linear color temperature database construction method, a color temperature adjustment method and device, and an LED lamp. Background technique [0002] LED lamps have many advantages such as high efficiency, energy saving, environmental protection and long service life, and are widely used in stage, film and television lighting. Although LED lamps perform well in many aspects, most LED lamps have a single color temperature when they leave the factory, and CRI (Chinese name is color rendering index, which means color rendering, which represents the degree of color fidelity) and TLCI index (Televison Lighting Cinsistency Index, which represents TV light source) Consistency index) and other optical parameters are low, it is difficult to capture high-definition and real TV pictures when the camera is shooting, and it is difficult to meet the use requirements in places with high requirem...
