Problems solved by technology

However, the light currently used in phototherapy is often monochromatic strong light such as blue light or white light with high brightness, or only a few segments of color temperature changes, which cannot fully simulate the color temperature and illuminance changes of the sun from morning to dusk

Abstract

The invention provides an illuminating device with gradually changed color temperatures. The illuminating device comprises an illuminating module and a control module, wherein the illuminating module is used for generating illuminating light with a plurality of different color temperatures, and the control module is used for controlling the color temperature change of the illuminating light so that the correspondingly changed color deviation value of the illuminating light is smaller than 0.006 when the color temperature changes. In addition, the color rendering index of the illuminating light with different color temperatures is respectively greater than 90 so that the sunlight change is completely simulated.

Description

technical field [0001] The invention relates to an illuminating device, in particular to an illuminating device with gradient color temperature. Background technique [0002] At present, there are lamps on the market that use red, green, and blue light-emitting diodes (RGB LEDs) for color mixing, but this type of lamps is generally only suitable for situational lighting and background lighting. The color rendering is less than 70, and the color rendering that does not meet the indoor lighting requirements specified by Energy star needs to be greater than 80. [0003] In addition, the existing dimmable lamps generally can only present three kinds of lighting lights with color temperatures of about 2800K, 4000K and 6500K. Such dimmable lamps generally use RGB LEDs or cyan and red crystal LEDs plus yellow phosphor to construct LED lamps with adjustable color temperature, but the color temperatures of such products cannot all meet The color rendering specified by Energy Star i...
