Q:Shoot the transformer output 12 v 20 to 50 w lamp is LED12V 4 w can use excuse me?

The big horse car, certainly can carry, isn't it. And is not a small cart. Besides using 4 w is not in order to save electricity The heart bold use. No problem!

Q:How to adjust the light in the home

See shoot the lamp to drive quality Big drivers are generally produced, performance is strong, the quality guaranteed. Small factory drivers are generally purchasing finished product driven, quality is uneven. 3: check the lamp parameters 1. The main parameters of LED lights, especially in high power LED lamp bead has a luminous efficiency and color rendering index, index of the luminous efficiency is 80-100 LM/W, must be greater than 80 LM/W, but the indicators are in growth, next year will reach 100-120 LM/W. Color rendering index is 0.8, the index is unnecessary to pursue more than 0.85, unless you are engaged in painting on color high requirements of the job.

Q:Sitting room condole top round with tube lamp or LED lamp good?

Tube lamp brightness is general, if the home of two Suggestions to shoot the light, the effect is better you know [like]

Q:LED lamp biggest can do how many watts?

3 w. Following is the specific features of high power led lamp product. Product specification 1, working voltage: 12 v 2, working current: 700 ma high-power lamp, the maximum power: 3 w Lm, luminous flux value: 120-120 5, color temperature range: 2700-6500 k 6, light Angle: 30 degrees 7, emitting light colors: white/warm white 8, the working temperature: - 20 ℃ to + 85 ℃ 9, the shell material: aluminum alloy 10, the service life: 50000 hours High power LED lamp appropriate beauty can be divided into two kinds: one kind of relatively large total power lamp for our products. Such as PAR lamp. Another as the light source adopts high power (1 w and more than 1 w) LED to shoot the light

Q:LED to shoot the light flashing or not on how to deal with?

You use multimeter to play your first whether the voltage stability?

Q:The sitting room condole top LED lamp wattage is commonly? How many watts of the LED lamp have?

LED is very good to recognize a beads is there are a few 1 w LED beads is a few watts of light. LED tube light, too, is the LED tube light to shoot the light are the same.

Q:Why turn off the switch and dim the led lamp

As if there is possibility is zero wire connection, received a zero on the line, also may be long bright, just happened to our family.

Q:Drive power supply with a what kind of specification, can be in parallel two 3 wled shoot the light

For example, A 3 w lamp current is 0.15 A, are two parallel is 0.3 A, then you have to choose the 0.3 A constant current source circuit to the two lamp power supply at the same time.

Q:Store decoration, good track shoot the lamp to LED lamp or metal halide lamp is good?

Hot metal halide lamp, power consumption, most of them are in the store to choose LED now, I also changed, in the store is to use ESSAC brand to shoot the light,

Q:How can you make the led lamp not dazzling

For general lighting, people need more white light sources. Hair white light LED successful development in 1998. This LED to GaN chip and yttrium aluminum garnet (YAG) packaging together. GaN hair blue chip (lambda p = 465 nm, Wd = 30 nm), high temperature sintering of YAG phosphors containing Ce3 + yellow light shot after the blue light excitation, peak 550 m nled lamp. Blue LED substrate is installed in the bowl reflection cavity, covered with thin layer of resin mixed with YAG, about 200-500 nm. LED substrate from the blue part is absorbed phosphor to another part of the mix blue with yellow light from fluorescent powder, we can get more white light. For InGaN/YAG white leds, by changing the chemical composition of YAG phosphors and adjust the thickness of phosphor layer, can obtain a variety of white light color temperature 3500-10000 k. This by the method of blue leds for white light, simple structure, low cost, high technical maturity, so use the most.
