- Q: Buy what good LED lamp? How to judge the quality of lamps and lanterns is good or bad
- Lights, namely the number of lumens per watt, LM/W, he reflects the energy-saving performance of lamps and lanterns, power saving, the more good lamps and lanterns, the higher light efficiency. Current leds and compact fluorescent lamps and lighting, with the improvement of LED lights, CREE possible amount of output this year 186 lm/w illuminant. Cash supply high power DC - DC DC converter, DC booster, 36, 48 v/v / 60 v electric inverter, electric vehicle intelligent DC converter. 24 v - 72 v electric vehicle controller, etc...
- Q: Led lamp can use ordinary incandescent dimmers adjust brightness.
- Because, currently on the market for the most part common dimmer and transformer is after cutting, and also is uneven levels, coupled with the decoration of the LED three bead lamp manufacturing estimate is not a big company, compatibility cannot guarantee, so the judgment on the basis of my experience, 99% installed, shoot the light will be flashing, if that move light will flash more severe; If you meet with protection do poorly LED lamp or dimmers, maybe, not LED lamp burned, is dimmer was burnt for high current.
- Q: How much time LED lamp life
- In general, LED the theory of life over 100000 hours, but the LED on the power requirement is strict, the LED lamp is not can be directly to the civil 220 v power supply, there must be a special power supply first, so the service life of LED lamp is the power supply and LED a common life
- Q: A few questions about LED lights
- 1 power supply voltage must be the same as the load, the power of the output current is larger, can provide the greater the power, the power of the load ability is stronger, so the output voltage of 12 v, the power of the output current of 700 ma can be used for you to shoot the light. Of course, if a larger output current of the power supply can also use just a little too wasted. 2 and 3 for the power supply voltage of 24 v, most likely have to burn the load (leds and circuit component), if want to use, with a voltage divider to be available 24 v down to 12 v. 2 the output current and load is the same, but actually does not reach 350 after partial pressure and loss ma output, so 2 after decompression can not use or scrape can be used. 3 the same supply voltage is too high to buck can use until about 12 v, otherwise it will burn, 700 ma output current can meet the requirements of shoot the light. Summary: the power of the output current must load than old do line, otherwise due to the load is too heavy to burn the power supply, power supply voltage and load the same or close to, can have a little error, but the difference is too large, high voltage too much, may burn load circuit and LED (lamp), is too low, could not move or inefficient work load and the load is not work.
- Q: What is the difference between LED track lamp and track light?
- Track light and LED ceiling lamp and the difference between a thing in common: Thing in common: both are LED lamps and lanterns, the shell is aluminum structure, can adjust the light Angle, to display lighting.
- Q: Would the LED light clothes according to rub off
- Will, I hang clothes is a bit long period of time under such as color change
- Q: A transformer with 10 led to shoot the light, to buy what kind of transformer?
- 10 only 3 w LED series, high efficiency, but high output voltage, 9.6 V * 10 = 96 V, filter capacitance pressure is high also, only 1 circuit, all is not lit up. Current 300 ma, power = 96 v to 102 v * 300 ma = 28.8 to 30.6 W, considering the power reserve, it is recommended to use 40 W constant current source.
- Q: Best lighting distance of LED to shoot the light
- Exposure to distance over 50 cm, 100 cm, 280 cm is the best distance "Here refers to inch, TV and so on. 1 inch = 2.54 cm. namely 4 inch = 4 * 2.54 = 2.54 cm. The 10 cm 6 inch = 6 * 2.54 = 2.54 cm. That is 15 cm 8 inch = 8 * 2.54 = 20.32 cm. The 20 cm Household size of tube light general again between 60-120 - mm, the size of the chandelier is bad to say about 30-100 cm, absorb dome light from 10 cm to 60 cm, go to the market of lamps and lanterns choose according to their own situation
- Q: LED lamp biggest can do how many watts?
- Shoot the light is a broad concept, source of coherent light can be classified as to shoot the light, shoot the light, such as smallpox large wattage lamp can be classified into the light. In the industry generally called PAR20 size small lamp holder to shoot the light, this kind of lamp in accordance with the lamp bead quantity biggest can make 5 * 1 w, 3 * 3 w. Above PAR30 habit called PAR lamp, size is larger, 18 w can do it. Other large wattage of the gymnasium, outdoor project-light lamp, stage lamp wattage do 200 w is very normal. The hope can help you
- Q: LED to shoot the light flash when open, a period of time is normal
- Should be and the power is larger, the relationship between the power control chip not fully launched, burp in state.
