- Q:The voltage of the LED lamp is about how much
- No, now the best solution is a string of ten. And then in parallel. Voltage is controlled in 32 v, with constant current source driver. Safety, high efficiency
- Q:How many watts appropriate general led desk lamp
- Advised to choose a well-known brand LED bulbs, LED bulbs now the price is not expensive,
- Q:Low voltage LED desk lamp belongs to the scope of 3 c certification
- Low voltage LED lamp -- -- -- -- -- is 220 v electricity, or the battery? Pick up the 220 v power will have to do the CCC certification
- Q:When did you buy? If it is just bought, suggest you use first photoelectric charge again
- LED, LED because of the different luminous principle, eliminate the stroboscopic and has high photosynthetic efficiency and pursue higher photosynthetic efficiency potential Advantage is small volume, no stroboscopic, including UV, high light efficiency, using high quality chip (OSRAM, day, and the name of the CREE) products can reach more than 80 or 80 color and has a long life The disadvantage is that the current national standard uncertainty, the products on the market anomalies chaos, most manufacturers use inferior chip led to less than 50 color... And LED chip due to poor use drive electric power are different, such as chip array and flashing brightness difference problem In a word, If conservative and don't care under the condition of light, it is best to use halogen light source to read; Care about energy saving problem use energy-efficient light bulbs, but must pay attention to choose big, because of the small manufacturer use halogen powder phosphor color rendering index less than 70, the same is not suitable for reading; If the pursuit of high-end, strict energy-saving, wish longevity noodles and the modelling of traditional light source, can choose LED products, but the best choice in the lighting industry's top brands and formal channel, so as to the quality of the products
- Q:What kind of USB power adapter for a LED light source is a USB power supply lamp?
- 5 v charger for charging the mobile phone can usb lamp power supply for 5 v voltage
- Q:Card lamp, LED desk lamp can take a plane
- Look at the battery storage is not too large should be ok
- Q:New LED lamp USES "magnetic -" the voice from time to tome, how to eliminate the noise?
- Immediately change demand manufacturer to you, do not use the circuit pressure out of the question, you can understand for the power supply circuit is out of order, continuous use may cause a fire may!
- Q:I had had a 20 leds rechargeable lamp, then the battery is broken
- The desk lamp of you already can charge (should be 220 v) you can directly with charging power supply should be bright?
- Q:Long amount of brand of LED desk lamp capacitor charging Fried v100uf 50
- This LED desk lamp, 220 v power supply is to step down by means of capacitance current limiting, once the no-load, after rectification voltage will be increased to 310 v, 220 v x under the square root of 2), seconds kill the capacitance of the withstand voltage 50 v. So, this kind of failure must first check whether the no-load, normally the power circuit of the load is the battery, check the battery cables are broken, the charging current limiting resistor is burned, if these are no problem check current limiting capacitance itself isn't breakdown (usually the breakdown causes 220 v over-current, empty trip meeting).
- Q:LED lamp base fever is normal
- Soon open lamp base is a bit hot, it is possible, because the LED need to drive to work, drive a similar electronic transformer, provide the LED constant current work, if the drive power design are critical, the switch of the transformer, power tube heat dissipation is not good, and relatively large current, will be hot
