Does the average LED light can be dimmer?
Support, LED lamp bead, generally in more than 2 ma of current can light up, just want to control to the proper current products, cannot too big, such as small products around 0.2 W LED current around 20-40 ma, so at the time of adjusting the brightness, can't go over the top! We commonly use LED lamps to use this way to adjust the luminescence brightness of the product!
For lighting LED lights can be said to be the increase brightness, main effect is to increase the units on the effective area of light irradiation intensity, minimizing scattering absorb light power elsewhere. Different effect of different light cup design, selected a design of LED lamp cup, light source, the same, the irradiation of light intensity also should be a little change, this time by light cup is not only can adjust the brightness, need to adjust the light source, which can adjust the brightness by other means.
Er, you mean the encapsulated LED light or module? This supports external adjustment, and the larger the current in the rated power, the stronger the glow, and the greater the use of a large current for the heat dissipation
This is not necessarily, such as with step-down switching device (rectifying step-down oscillation circuit, etc.) can not directly via step-down current limiting to adjust brightness, otherwise it will lead to damage of circuit inside the lamp. Also has the general regulation of light-emitting diodes (leds), within the scope of the manufacturer to provide the parameters of the commonly used thyristor voltage regulation can be directly used dimmers change LED current size to adjust the brightness, dedicated with its designed with adjusting device.
A lot of it depends on how many W you want, or how much light flux is, the little product is 3014/2835/5730/7030, if you want the power type, 1W / 3W, COB integration! All have, breed a lot of, can dc power supply!
