Some embodiments of the invention are described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
First embodiment
The present embodiment provides a method for setting a dimming range, referring to fig. 1, including:
s1: the number of the gear positions of the dimming gear positions and the luminous flux percentage A% of the lowest gear position in the dimming gear positions are obtained.
The luminous flux percentage is the percentage of the luminous flux generated by the gear to the maximum luminous flux of the light-emitting device, the number N of the gears is a positive integer and is more than 1, and A is a positive number.
S2: determining a luminous flux change reference value X between adjacent gears in the dimming gears according to the gear number and the luminous flux percentage A%, wherein [ A X (N-1) ] -100, and X is a positive number;
s3: and determining the luminous flux percentage of each dimming level according to the luminous flux change reference value X.
Because human eyes do not sense the relative change value of the luminous flux but sense the multiple of the change value, in the scheme, the luminous flux change reference value X is obtained when the luminous flux meeting the highest gear is 100% through the number of the gears and the luminous flux percentage A% of the lowest gear, the luminous flux change value of each gear in the dimming gears can form multiple level increase based on the luminous flux change reference value X, when the light-emitting device adjusts in the high gear, the change of the luminous flux is still obvious, the light-emitting device accords with the visual perception of human eyes, and the setting is more scientific and reasonable.
Alternatively, step S3: determining the luminous flux percentage of each dimming level according to the luminous flux change reference value X, wherein the method comprises the following steps:
and determining the luminous flux percentage of the ith gear in the N dimming gears as [ A X X (i-1) ]%, wherein the value of i is 1 to N.
In the above scheme, the multiple between all the gears is set to be uniform, the multiple is a determined luminous flux change reference value X, when in gear adjustment, we assume that the luminous flux percentage a% of the lowest gear that can be reached is 10%, and the number of gears is 5, then the luminous flux change reference value X can be obtained as 1.78 according to the formula [ a × X (N-1) ]%, where a is 100%;
since the percentage of luminous flux of each gear from the lowest gear to the highest gear is [ A ]%, [ A X ]%, [ A X3 ]%, [ A X4 ]%, [ A X (N-1) ]%, the percentage of luminous flux of each gear can be 10%, 17.8%, 31.6%, 56% and 100%;
assuming that the maximum luminous flux of the light emitting device is 300lm, the luminous fluxes generated by the gears can be finally obtained to be 30lm, 53lm, 95lm, 169lm and 300lm according to the luminous flux percentages of the gears.
Alternatively, step S3: determining the luminous flux percentage of each of the dimming levels according to the luminous flux variation reference value X, comprising:
the percentage of luminous flux in the ith of the N dimming levels is determined to range from ([ A X X ^ (i-1) ]% -B%, [ A X X ^ (i-1) ]% + B%), i takes on values from 2 to (N-1), and B is a constant and positive number.
In this embodiment, setting the multiple between all the gears to be different but still to increase in multiple steps, the luminous flux percentage of each of the final dimming gears is determined by the luminous flux change reference value X, and when the gears are adjusted, following the example where the luminous flux percentage a% of the aforementioned lowest gear is 10% and the number of gears is 5, the reference values of the luminous flux percentages of the respective gears are 10%, 17.8%, 31.6%, 56%, 100%;
after obtaining the reference value of the luminous flux percentage of each gear according to X, the final luminous flux percentage of the intermediate gear is shifted up and down by B% according to the reference value of the luminous flux percentage, and when the shifted value B% is 10%, the luminous flux percentage of each gear is 10%, (7.8% -27.8%), (21.6% -41.6%), (46% -66%), (100%) is obtained.
As another embodiment of the above scheme, after the reference value of the luminous flux percentage of each gear is obtained according to X, the final luminous flux percentage of the lowest gear and the middle gear is up-down shifted by B% from the reference value of the luminous flux percentage.
For example, the percentage of light flux a% in the lowest gear is 1%, the number of gears is 5, and after the calculated reference value of the percentage of light flux in each gear is 1%, 3.16%, 10%, 31.6%, and 100%, the percentage of light flux in each gear can be (0% -11%), (0% -13.16%), (0% -20%), (21.6% -41.6%), and 100% according to the floating value of 10%, of course, the highest gear can also be determined according to the given floating value, the range of the percentage of light flux in the lowest gear is at least 0%, and the range of the percentage of light flux in the highest gear is at most 100%.
As another embodiment of the above scheme, after obtaining the reference value of the luminous flux percentage of each position according to X, the final luminous flux percentage of each position is shifted up by B% and down by C% according to the reference value of the luminous flux percentage, and the above scheme is performed when C% is the same as B%, and the calculation method of the present embodiment may refer to the calculation procedure of the above scheme.
Alternatively, at step S3: after determining the luminous flux percentage of each dimming level according to the luminous flux variation reference value X, the method further comprises the following steps:
