Q:What about a three-male led light?
In general. Mitsuo main strengths is the electronic ballast and match the lamp panel stent engineering lighting products. Led is given priority to with light matching a variety of lamps and lanterns, heat dissipation problem. Personal opinion. Hope to help you answer.
Q:Reinstall the 2 LED lamp are in parallel, one open and how a first shines a stare blankly only 1 SEC,
Now is not to say that on the driving power supply technology is very poor, so belong to normal phenomenon. You can use it
Q:The sitting room bovine eye lamp with led lamp or led the ordinary light
Name is different, have no obvious boundary Real bovine eye lamp part is prominent in front of the condenser Average sitting room with normal LED lamp line, concrete can @ me
Q:Why turn off the switch and dim the led lamp
LED shoot the light is long, the inside of the wick will burn red hot, when power off, burn the red hot wick will not immediately cooled, there seem to be careless, so slowly after cooling is not lit up.
Q:About LED tube light to shoot the light of common sense
Do you want to light is adjustable brightness or light color? If it is a variable degree of directly replace driver IC is ok, if is the color temperature of the lamp bead can not suitable for you. 3. Your driver output voltage and current, the series multiple lamp after share current, light can't take much more
Q:Led to shoot the light color temperature 3000 k what do you mean who knows
Color temperature (colo (u) r temperature) is visible in photography, video, publishing, and other fields has important application characteristics. Light source color temperature is by comparing the color and theory of thermal blackbody radiator. Hot blackbody radiator with the colour of the light source to match the kelvin temperature is the color temperature of light source, it is directly associated with Planck's blackbody radiation law.
Q:What clothing store LED lamp, LED lamp can choose?
Shoot the light is placed near the ceiling upper or furniture, also may be placed on a wall, dado or play crural line. The light immediate illuminate is on the items to be highlighted implements, to highlight the subjective aesthetic effect, to highlight atmosphere and unique environment, abundant, rich and colorful artistic effect. Shoot the light is downy, elegant, can play a leading role to the overall lighting, and local lighting, foil atmosphere. 1, save electricity: shoot the light reflectors with powerful function of refraction, around 10 watts of power can produce a strong light. 2, concentrated: concentrated light, can highlight or emphasize a particular object or space, adornment effect is obvious. 3, comfortable: color close to natural light that shoots the light, the light reflection to metope, not dazzling.
Q:Led to shoot the light, the 12 v transformer and transformer can general ordinary lamp?
Transformer are interchangeable, but LED is a dc power supply, if the pressure after the bridge rectifier, more than 12 v, also need to consider the LED string and method and current limiting resistor.
Q:A few questions about LED lights
First, the power supply current exceeds the LED light source of the load current, lead to LED lamp bead light failure quickly, even destroyed. Solution: 1, to reduce the input current; 2, the LED light source for more than 45 mil 3 w light bead, so each lamp bead to withstand current of 700 ma, but this time is 9 w, must increase the radiator. Second, the high voltage is bound to burning lamp bead,, the only way to avoid lower voltage, series resistance. Third, voltage and current are beyond ratings, is sure to burn, not saved. Can only cut down the voltage and current are. Method is still the same, want to directly change the power supply, either in LED series resistance voltage drop flow in the circuit
Q:The LED lamp heating temperature of 65 ° high
But if the light source on the heat doesn't pass all the shell, then 65 degrees it is hard to say, analyze the hot flow channel of light.
