- Q: Charging indicator has been on desk lamp, led lamp is not bright after rotary switch
- After the first thing you should fill the electricity, using a multimeter to check the battery (black pieces) to have electricity, normal about 4 v, no electricity is the battery is bad, to replace the battery. If there is electricity, check the circuit board components have obvious damage, there is a circuit board is broken, no potentiometer (knob) could be broken. Can now be considered your element is broken, makes the led indicator light, hope to adopt!
- Q: LED rechargeable lamp, can you tell me how long does it take to charge for the first time?
- And LED rechargeable lamp used for the first time, should be charged more than 10 hours. LED rechargeable lamp maintenance: LED rechargeable lamp if it is not because the excess voltage or short circuit, usually don't burn out.
- Q: How to distinguish whether the led lamps and lanterns glare, is there a standard?
- Wu caused cause people watching and watching! If has the attention of people is a bad light. The visual environment unfriendly! General LED panel light is good. Problem is that there are a lot of high-power lamp bead or COB integrated chips into the glare of lamps and lanterns is very serious!!!
- Q: Are sold on the market in recent years that most students rechargeable lamps with the sort of, call what name I also do not go up, anyway, not expensive, I would like to ask you about the charging lamp charging commonly how long?
- Charging time depends on the built-in rechargeable battery capacity and provide the size of the charging current charging circuit. General capacity/charging current multiplied by 1.2 is about the same time.
- Q: Pupils to do homework with good desk lamp is yellow light or white light is good
- Desk lamp is good, eyes comfortable is the most important. Actually now the LED for the eyes, is really bright flashing eyes, but in the long run really uncomfortable. Old lamp luminous tube flashing LED lights, dazzling, entanglements...
- Q: Low voltage LED desk lamp belongs to the scope of 3 c certification
- See were independent of a body or power supply Independence is the power to do 3 c lamp don't have to do
- Q: LED rechargeable desk lamp the internal rechargeable battery, charging voltage is how old?
- Charging voltage high, will affect battery life; But some desk lamp is 6 v or 9 v battery. So it is best to open it, take the battery voltage shall prevail.
- Q: LED lamp rushed into electricity, no battery is bad, but is not into electricity, charging indicator light (not bad) didn't also bright, is how to return a responsibility?
- Light is not bright, can be sure is there is something wrong with the wire or internal charging circuit has a problem. Judge fault: 1, if the line is broken, looking for businesses of the same wire, in a first try (don't have to buy wire to test), indicator is not; 2, the light is bad, but little chance (if this is the case, the battery doesn't charge into the electricity, the battery has high pressure resistance state sulfide, battery need to be repaired). 3, internal charging line fault: most likely internal CBB capacitor to boil road, need to change. For this kind of lamp, the most easily broken electronic components in the charging circuit is the CBB capacitance. Can go to the repair shop repair. Only more than 1, 3 kinds of possibility is high, the highest 3, was ruled out small battery (internal small battery) problem, because the light is not bright, batteries to electric light advocate the lamp, that the battery is resistance, capacitance resistance step-down charging circuit to charge of no-load voltage can reach more than 300 v, is impossible, and no current flows through the indicator as long as is good will on, even if the battery fully charge it into electricity, indicator light will be bright. I have a problem is battery repair instrument design engineers, can ask me, I design the battery repair instrument can repair indicator but any vulcanization of battery and charge it into electricity. There is a way to judge whether there is a current through the, is at the moment of plugged into the plug has a tiny 1 of "pa", or "chip", close to the ear, can hear, careful observation can even see tiny spark, then the CBB capacitance not bad, but the light is bad, and the battery has the possibility of sulfide. Downstairs and a brother named longsheng fushun said about the battery internal resistance and resistance capacity no-load voltage of charging circuit, considered a battery sulfide failure (charge it into electricity, indicator), but not necessarily.
- Q: How many watts of 10 square meters of the bedroom with led bulbs Warm white or white
- LED bulb specifications now have 3 w, 5 w, 7 w, 9 w is common, like how to buy big brand certainly better brightness, 5 w and close to the original energy-saving lamps 10 w, about half is the province. 10 square room seeing you is what lamps and lanterns, with an estimated 5 w and 7 w enough. Warm white or white look like, do you want to create a warm environment, for example, the preferred warm white, want to feel a little bit bright choice is white.
- Q: Desk lamp good still tube of good to buy LED strips? Search light tube usually can use a few years need to change?
- A low power consumption and lower power LED that LED the working voltage of is generally 2-3.6 V. The working current of 0.02-0.03 - A. That is to say: it consumes the electricity is not more than 0.1 W. 5, green environmental protection, high efficiency and energy saving, the LED is made from non-toxic material, unlike fluorescent mercury can cause pollution, at the same time, the LED can also be reused.
