- Q:The LED lamp aging is what mean
- Aging, sophisticated, right is to make the structure of lamps and lanterns, electrical, light up each other and so on various parts, to adapt to each other. Is in the environment of lamps and lanterns lit 48 h bai, how current is too large, as large as in actual use is aging, 220 v to 220 v, 12 v, 12 v, according to the actual application environment to do is ok!
- 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:How to choose an outfit with the lamp? What is the need to change especially pay attention to?
- Angle of light Must notice when buying LED lamp its search better light Angle, make its in use process does not produce glare, such as the Angle of 20 °, light down to be in this range, the outside of the LED lamp irradiation Angle should be can't see the strong light, so as to ensure comfortable appropriate home lighting design
- Q:18 w led lamp flashing how to return a responsibility
- Where should be the power supply, power supply is generally in the inside of the lamps and lanterns, as long as you open it to see a plastic box, that is the power supply, you can put it in.
- Q:1. I bought the LED tube light, there is some light is driven with constant current, while the input voltage is 220 v, but tend to be low voltage dc output voltage, there are some inserts the 220 v can directly, didn't see any of the constant current drive, so is built into the still say there are two kinds of LED tube light, is a kind of the working voltage of the dc low voltage, a kind of ac 220 v. 2. About the LED tube light, dimmer, I already according to one of the LED constant current drive found the corresponding LED light, that if I was the LED directly to the adjustable light can directly replace the LED constant current drive.
- 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:Why turn off the switch and dim the led lamp
- A common cause of ED lights flashing and the solution: After turn off the power supply LED lights flashing, check the switch control is zero. If the correct wiring may refer to the following methods: The human eye can generally perceived frequency of 70 Hz light flashing, higher than the frequency does not perceive. So in LED lighting applications, if the pulse signal frequency is lower than 70 Hz low frequency component, the human eye will feel the shine. In the specific application, of course, there are many factors may lead to LED lights flashing. For example, in an off-line low power LED lighting applications, a common power supply topology structure type is to isolate the flyback topology. In accordance with the "energy star" solid-state lighting standards from line 8 w LED drive GreenPoint ? reference design as an example, as a result of the flyback voltage stabilizer sine square wave power conversion did not provide primary offset constant energy, dynamic self-supply (DSS) circuit may activate and trigger light flashing. To avoid this problem, must enable primary bias to partial discharge in each half cycle, accordingly, need to choose appropriate constitute the bias circuit of capacitance and resistance value.
- Q:What is main purpose of the LED lamp
- Save electricity saving life is long Art effect is good The light is downy healthy variety does not hurt eyes
- Q:How to choose to shoot the light
- LED brightness: different brightness LED price, ordinary brightness and highlight LED price comparison. Therefore, when purchasing must know oneself need is what kind of brightness, such ability accurate positioning their products.
- Q:Buy what good LED lamp? How to judge the quality of lamps and lanterns is good or bad
- Drive power supply, and good driving power can guarantee the overall life of the lamps and lanterns, LED the theory of life and the life of the general drive power supply is 100000 hours less than 100000 hours. In order to guarantee the overall life of the lamps and lanterns, driving power supply is also a key link; On the other hand must be LED constant current drive, if using a low-cost constant voltage driver will shorten the service life of the LED. As an ordinary consumers how to identify the LED driver power supply of the good or bad? See a few parameters, droop, service life, light efficiency, and quality assurance period. To provide quality assurance for a long time factory production quality LED lamps and lanterns is good.
- Q:Household LED lamp directly on the ceiling above the glass, glass temperature is higher, matter?
- You mean the glass or usage of lamps and lanterns more important matters, Let's enhance heat dissipation area, or to change the lamp. If the heat dissipation of lamps and lanterns can't very good, affect the life don't say Is a waste of money. Advice is to buy good LED lamps and lanterns, buy poor than energy-saving lamps?
