Method for regulating color temperature of light source in dimming lamp

Abstract

The invention discloses method for regulating a color temperature of a light source in a dimming lamp, in which the light source does not need to be customized. The method comprises the step that: atleast two groups of LED lamp beads with different color temperatures are adopted to form the light source of the dimming lamp, i.e., in the light source, a color temperature value of one group of LEDlamp beads is the maximum and is the maximum light source color temperature value, and a color temperature value of one group of LED lamp beads is the minimum and is the minimum light source color temperature value; by respectively changing light-emitting intensity of the at least two groups of LED lamp beads, when brightness of the light source is regulated, the color temperature of the light source is kept unchanged and is a random color temperature value between the maximum light source color temperature value and the minimum light source color temperature value; or by respectively changingthe light-emitting intensity of the at least two groups of LED lamp beads, when the brightness of the light source is regulated, the color temperature of the light source is kept changed between tworandom color temperature values between the maximum light source color temperature value and the minimum light source color temperature value, and the brightness continuously becomes small, and the color temperature gradually becomes small. The regulation method disclosed by the invention can be widely applied to various dimming lamps.

Description

technical field [0001] The invention relates to a dimming lighting fixture, in particular to a method for adjusting the color temperature of a light source in a dimming lighting fixture. Background technique [0002] At present, in order to realize the DimToWarm (dimming and warming) function of traditional dimming lighting fixtures, their light sources are usually customized. In this case, on the one hand, the manufacturing cost is increased. On the other hand, because customization takes time, the procurement cycle become longer, thereby prolonging the production cycle of dimming lighting fixtures, and it is likely to cause waiting for work during the period, resulting in an increase in production costs. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for adjusting the color temperature of the light source in a dimming lamp that does not require customization of the light source. [0004] In order to ...
