Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings of the description.

[0030] Such as figure 1 As shown, a color correction method for a color light lamp, the lamp includes a controller, and the controller controls a light source with three primary color LED chips to emit light, and the correction method includes the following steps:

[0031] (1) Set a set of UC parameter initial values ​​of RGB three-primary color ratio in the lamp controller; UC parameter is a set of RGB three-primary color ratio parameters built into the lamp, which represents the ratio of RGB three-primary color, not brightness, before the lamp leaves the factory The initial value must be set first to work normally. The initial value of UC parameters: R: G: B = 255: 255: 255; the initial value of UC parameters is to make RGB work at full brightness. Therefore, the UC parameter value is not fixed and should be adjusted according to the color cast of...

Abstract

The invention discloses a colour correction method for a coloured light lamp. The method comprises the following steps: (1) setting a group of UC parameter initial value at RGB (red, green and blue) ratio in a lamp controller; (2) selecting a standard sample plate lamp, and measuring the monochrome illumination RL0, GL0 and BL0 of a sample plate lamp; (3) selecting one corrected colour cast lamp, and measuring the monochrome illumination RLX, GLX and BLX of the corrected colour cast lamp; (4) calculating the colour deviation of the corrected colour cast lamp and the standard sample plate lamp; (5) selecting the colour with the minimum amplification, setting the UC parameter value of the colour to be maximum, and taking the colour illumination as the reference to calculate the UC parameters of other two colours; and (6) taking the calculated UC parameter value as a calibration value, and sending the calibration parameter to the corrected colour cast lamp to be stored by a controller SA102. The colour of the colour cast lamp is corrected to enable the colour of each batch of products to be consistent and guarantee product consistency, and purchasing difficulty is lowered.

Description

technical field [0001] The invention relates to the field of LED lighting, in particular to a colored light lamp whose light source uses LED chips of three primary colors to mix light. Background technique [0002] Due to the rapid development of the light efficiency of LED chips, and the RGB cannot be improved synchronously, the color of each batch of products is inconsistent, the product consistency is poor, and it also increases the difficulty of procurement. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for color correction of color light lamps. Through the color correction of color cast lamps, the color of each batch of products is consistent, ensuring product consistency and reducing procurement difficulty. [0004] In order to solve the above technical problems, the technical solution of the present invention is: a method for color correction of a color light lamp, the lamp includes a controller...
