Problems solved by technology

[0002] At present, light-emitting devices on the market, such as TV screens, advertising display screens, and lamps, have dimming functions. Most of the light-emitting devices can adjust the brightness. Equal luminous flux adjustment, for example, as follows, the total luminous flux of the lamp is 300lm, and it is necessary to achieve 5 levels of dimming, each gear is 300lm, 240lm, 180lm, 120lm, 60lm. When changing from the 240lm luminous flux of the fourth gear to the 300lm luminous flux of the fifth gear, the change of the luminous flux is not obvious, only a 1.25 times change. The constant luminous flux dimming method on the market has the disadvantage that the light change is not obvious when it is at a high level

[0041] This embodiment provides a method for setting the dimming gear, refer to figure 1 ,include:

[0042] S1: Obtain the number of dimming gears and the luminous flux percentage A% of the lowest gear among the dimming gears.

[0043] The percentage of luminous flux is the percentage of the luminous flux generated by the gear to the maximum luminous flux of the light emitting device, the number of gears N is a positive integer greater than 1, and A is a positive number.

[0044] S2: According to the number of gears and the luminous flux percentage A%, determine the reference value X of luminous flux change between adjacent gears in the dimming gear, where [A*X∧N-1=100, X is a positive number;

[0045] S3: Determine the luminous flux percentage of each dimming gear in the dimming gear according to the luminous flux change reference value X.

[0046] Since the human eye is not sensitive to the relative change value of the luminous flux, but to the multiple of the change value...

Abstract

The invention discloses a method for setting dimming shifts, a shift adjusting method, a device and a system. The method for setting dimming shifts comprises: obtaining the number N of dimming shiftsand the luminous flux percentage A% of the luminous flux of the lowest shift in the dimming shifts to the maximum luminous flux of a light-emitting device; according to the number N of the shifts andthe luminous flux percentage A%, determining a luminous flux change reference value X between adjacent shifts among the N dimming shifts; and according to the luminous flux change reference value X, determining the luminous flux percentage of each of the dimming shifts. The method obtains the luminous flux change reference value X based on the number of the shifts and the luminous flux percentageA% of the lowest shift. The luminous flux change value of each shift in the dimming shifts can be multiplied based on the luminous flux change reference value X. When the light-emitting device is adjusted between higher shifts, the change of the luminous flux is still obvious, which complies with the visual experience of human eyes and is scientific in setting.
