Description

Technical Field

[0001] The present invention relates to the field of dimming, and in particular to an intelligent dimming method for the chromaticity coordinates of a multi-primary color lamp. Background Art

[0002] Multi-primary color LED lamps produce the desired photoelectric effect by mixing multiple LED chips of different colors. These LED chips may include red (R), green (G), blue (B), yellow (Y) or other color LED chips. By adjusting their brightness and proportion, light of various colors and brightness can be produced. In the prior art, a batch of multi-primary color lamps use the same current parameters.

[0003] The inventor of this patent discovered at least the following technical problems in the prior art during the process of implementing a method for intelligent dimming of the chromaticity coordinates of a multi-primary color lamp according to an embodiment of the present invention: In multi-primary color lamps, a batch of multi-primary color lamps use the same current parameters, but due to the various components of the lamps, such as LED chips, circuit boards, lenses, etc., there will be certain tolerances during the production process, that is, the difference between the actual size or performance and the ideal value. These tolerances will cause differences in the light color parameters of each lamp, such as color temperature and chromaticity coordinates, etc. Even if they are designed to have the same photoelectric characteristics, there will be problems of different colors at the same temperature and different temperatures at the same color.

[0004] Same temperature, different colors, refers to the same color temperature but different colors, for example: two or more lamps look similar in color temperature, but there are differences in color. This difference may be manifested as a difference in color saturation, hue or brightness.

[0005] The same color but different temperature refers to the same color but different color temperatures. For example, two or more lamps look similar in color but have different color temperatures.

[0006] In summary, since the existing multi-primary color lamps uniformly use the same current parameters, the light color parameters of each lamp are different. Summary of the invention

BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Figure 1 The figure is a flow chart of a method for intelligent dimming of the chromaticity coordinates of a multi-primary color lamp according to an embodiment of the present invention. DETAILED DESCRIPTION

[0020] The embodiment of the present invention provides a whole-lamp chromaticity coordinate intelligent dimming method for a multi-primary color lamp, which solves the problem that the light color parameters of each lamp are different due to the existing multi-primary color lamps uniformly using the same current parameters.

[0021] In order to better understand the above-mentioned intelligent dimming method for the chromaticity coordinates of the whole lamp of a multi-primary color lamp, a detailed description will be given below in conjunction with the drawings and specific implementation methods of the specification. Obviously, the embodiments described in the present invention are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] like Figure 1 As shown, an embodiment of the present invention provides a method for intelligent dimming of the chromaticity coordinates of a multi-primary color lamp, including steps S1 to S5.

[0023] Step S1: setting the initial current duty cycle of each primary color R, G, B, Y.

[0024] In the specific implementation process, for example, the initial current duty cycle of each primary color of R (red), G (green), B (blue), and Y (yellow) is set, wherein the initial current duty cycle is within the range of 0-255. The staff can set the initial current duty cycle for the multi-primary color lamp based on experience, and set the initial current duty cycle of R to 150, the initial current duty cycle of G to 150, the initial current duty cycle of B to 150, and the initial current duty cycle of Y to 150. Of course, the initial current duty cycle can also be automatically set by software, which is not limited by the present invention.

[0025] Step S2: testing lamp data of the multi-primary color lamp.

[0026] In the specific implementation process, for example: a spectrometer is used to test the spectral power distribution, chromaticity coordinates, color temperature, color rendering index, flicker information, luminous flux, illumination and other lighting data of multi-primary color lamps.

[0027] Step S3: Determine whether the lamp data conforms to the standard lamp data, if so, end the test, otherwise proceed to step S4.

[0028] In the specific implementation process, for example: based on the lamp data of the multi-primary color lamp obtained by the test in step S2, it is determined whether the lamp data conforms to the standard lamp data. If the initial current duty cycle of each primary color R, G, B, and Y set in step S1 is the standard current duty cycle, after judging whether the lamp data conforms to the standard lamp data in step S3, the generated judgment result shows that the lamp data conforms to the standard lamp data, and the test is terminated. If the initial current duty cycle of each primary color R, G, B, and Y set in step S1 deviates from the standard current duty cycle, after judging whether the lamp data conforms to the standard lamp data in step S3, the generated judgment result shows that the lamp data does not conform to the standard lamp data, and the process proceeds to step S4.

[0029] Step S4: setting the current duty cycle step value according to the chromaticity coordinate difference between the chromaticity coordinate of the multi-primary color lamp and the chromaticity coordinate of the standard gear.

[0030] In the specific implementation process, for example: the chromaticity coordinates of the multi-primary color lamp are marked as (Xt, Yt), where the chromaticity coordinates are the chromaticity coordinates of the whole lamp, the standard gear chromaticity coordinates are marked as (Xc, Yc), and the chromaticity coordinate difference between the chromaticity coordinates of the multi-primary color lamp and the standard gear chromaticity coordinates is recorded as (Xd, Yd), where Xd=Xc-Xt, Yd=Yc-Yt. According to the chromaticity coordinate difference (Xd, Yd) between the chromaticity coordinates (Xt, Yt) of the multi-primary color lamp and the chromaticity coordinates (Xc, Yc) of the standard gear, the current duty cycle step value is set as follows.

[0031] When the chromaticity coordinate difference Xd or Yd is greater than 0.01, the current duty cycle step value is set to the first step value, and the value range of the first step value is 4-50. In practical applications, according to different chromaticity coordinate differences, the first step value is set to a specific value, such as 4, 15, 35, 45, 50, etc., which is not limited in the present invention.

[0032] When the chromaticity coordinate difference Xd or Yd is greater than 0.005, the current duty cycle step value is set to the second step value, and the value range of the second step value is 3-40. In practical applications, according to different chromaticity coordinate differences, the second step value is set to a specific value, for example: 3, 18, 25, 30, 35, etc., which is not limited in the present invention.

[0033] When the chromaticity coordinate difference Xd or Yd is greater than 0.002, the current duty cycle step value is set to a third step value, and the value range of the third step value is 2-30. In practical applications, according to different chromaticity coordinate differences, the third step value is set to a specific value, for example: 5, 10, 15, 25, 30, etc., which is not limited in the present invention.

[0034] When the chromaticity coordinate difference Xd or Yd is greater than 0.0002, the current duty cycle step value is set to the fourth step value, and the value range of the fourth step value is 2-20. In practical applications, according to different chromaticity coordinate differences, the fourth step value is set to a specific value, for example: 3, 8, 11, 15, 20, etc., which is not limited in the present invention.

[0035] When the chromaticity coordinate difference Xd or Yd does not fall within the above range, the current duty cycle step value is set to the fifth step value, and the value range of the fifth step value is 1-10. In practical applications, according to different chromaticity coordinate differences, the fifth step value is set to a specific value, such as 2, 3, 5, 7, 10, etc., which is not limited in the present invention.

[0036] Step S5: Determine whether at least one of the current color temperature, color tolerance, R9, Ra, chromaticity coordinate difference, chromaticity horizontal and vertical coordinate difference, chromaticity coordinate, and power of the multi-primary color lamp meets the preset conditions, and modulate the current duty cycle of at least one primary color of R, G, B, and Y according to the current duty cycle step value until the power, color temperature, color tolerance, Ra, and R9 of the multi-primary color lamp are within the standard range, save the current current duty cycle of each primary color of R, G, B, and Y into the lamp power supply, and end the test, otherwise jump to step S1 for repeated debugging.

[0037] Among them, the difference in the horizontal and vertical coordinates of the chromaticity is recorded as XYd, XYd=Xd-Yd, Xd=Xc-Xt, Yd=Yc-Yt, the chromaticity coordinates of the multi-primary color lamp are (Xt, Yt), and the chromaticity coordinates of the standard gear are marked as (Xc, Yc).

[0038] Among them, to determine whether at least one of the current color temperature, color tolerance, R9, Ra, chromaticity coordinate difference, chromaticity horizontal and vertical coordinate difference, chromaticity coordinate, and power of the multi-primary color lamp meets the preset conditions, a single parameter can be selected, such as determining whether the power meets the preset conditions, or any combination of two or more parameters can be selected, such as determining whether the current color temperature, color tolerance and R9 meet the preset conditions, and the present invention is not limited thereto.

[0039] The specific judgment sub-conditions for each parameter will be given below. In practical applications, a single judgment sub-condition may be selected from each parameter, or a combination of two or more judgment sub-conditions may be selected from each parameter according to the specific situation.
