Embodiment Construction

[0045] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0046] Among them, in the description of the embodiments of this application, unless otherwise specified, " / " means or means, for example, A / B can mean A or B; "and / or" in this article is only a description of associated objects The association relationship of indicates that there may be three kinds of relationships, for example, A and / or B may indicate: A exists alone, A and B exist simultaneously, and B exists independently. In addition, in the description of the embodiments of the present application, "plurality" refers to two or more than two.

[0047] As mentioned in the background art, the existing composite light source combined by various LEDs cannot effectively correct the color coordinates and / or luminous flux of the composite light when used, resulting in a certain gap between the preset co...

Abstract

The invention discloses a high-precision control module and method for a light source, including a light source, a drive circuit, a spectrometer and a processing unit; the execution method of the processing unit: S01: read the preset parameters of the light source and LED and the parameters detected by the spectrometer, and detect Compare the obtained parameters with the preset parameters to obtain the color coordinates, the offset vector of the color coordinates, the luminous flux and the luminous flux variation ratio; S02: If the luminous flux variation ratio and the color coordinates of the light source are within the set error range, return to the previous step. Otherwise, go to the next step; S03: If the color coordinates of the light source exceed the error range, calculate the color coordinates of the preset light source and the component vectors of the color coordinates of each LED, and adjust the luminous flux of each LED one by one in combination with the data in step S01 until the color coordinates of the light source Adjust within the error range, if the luminous flux variation ratio exceeds the error range, then adjust the current luminous flux of each LED synchronously with the set ratio until the luminous flux variation ratio is adjusted within the error range; S04: return to step S01.

Description

technical field [0001] The invention relates to the technical field of lighting devices, in particular to a high-precision control module and method for a light source. Background technique [0002] Composite light sources need to be combined with a variety of different monochromatic lights, and the control of each monochromatic light is a very important part, but at present, most of the adjustments to composite light stay on the intensity or light intensity, and the working process of the light source The color coordinate shift of the compound light in the medium cannot be precisely adjusted and corrected. [0003] For example, the utility model with the publication number CN205079080U relates to a flashlight with three light sources. The shell of the flashlight includes a lamp housing, a lamp tail, and a lamp cap. The LED lamp of the lamp board extends into the lamp hole of the lamp cup. Adjust the switch; the main point is that the lamp board is provided with LED lamps t...
