Checked before questions about color soft brightness, but no search to a more comprehensive explanation, consult everybody, since the

See someone explained that high colour temperature is cool color light and color in the two groups the brightness of the light, which from human visual Bai Guangnuan light appears on the cold light, etc.,
Brightness is can be used to adjust current or adjust pulse high level duty ratios,

That if I were in case to specify the color temperature adjusting brightness, is quite so I after adjusting the color temperature of circuit with pulse regulate and control the brightness???????

As well as adjust the color temperature, is equivalent to high level is high light pulse hypothesis, and adjusting the duty ratios to adjust the color temperature?

(myself playing out the question, think about if this is indeed) don't know what you have any opinion or advice

CodePudding user response:

Color temperature and brightness do not have what relation, associated with the color of the light color temperature, color temperature of three primary colors of light is three color temperature and the average color temperature, monochromatic LED spectral fixed, unable to adjust the color temperature, only multicolor LED by adjusting the color way to adjust the color temperature,

If to use two kinds of color temperature of lamp with mixed up, I used to do is this way

Quote: FPGA reference 1 floor?????? Response:

Ok thank you, I'll check the multicolor LED to adjust color, have a plenty of LED internal chemical mixed with different current (voltage) control different wavelengths of light, some with almost a lamp on the second floor there are multiple internal lights such as trichromatic three lamp bead, light gives a person the visual effect of pure color or mixed color on, don't know what kind of the first floor said

Because I am to do the led color temperature, brightness control, so I want to know that I can adjust the function of color temperature after circuit and adjust the brightness of the circuit, or is when adjusting the color temperature through other ways to adjust brightness? (I could be in fantasy ha ha)

Ok thank you, I find most of them are saying
