FAQ
- So only the halogen lamp, but is low voltage halogen lamp, need a rectifier, and halogen lamp itself temperature is high, pay attention to the heat dissipation, color rendering index selected 90-100, color WenXuan 2700 k, the best for you.
- Line loss, it is good to connect.Of course, can also according to component model and buy a change.
- Children lamp good choice led lamp is better
- Can, LED by natural white light bead (osram), tube made of three primary colors. Starting from protecting eyesight, try not to read for a long time, should have proper rest, look at the distance, eyes
- Study desk lamp high-power led is more appropriate
- Preferred the desk lamp of dc, because traditional 220 v ac 50 hz residual current fluctuations, causing light stroboscopic phenomenon. Stroboscopic is easy to cause eye fatigue, vision loss, deepen myopia. And preferred light yellow light, the light is warm, warm and comfortable, stable, not dazzling. Another is to see whether there is ultraviolet (uv) radiation.
- What led small desk lamp general battery
- That there are many, some with a dry cell, and also useful for lithium battery, in most cases is made with rechargeable lithium battery power supply
- LED lamp stroboscopic serious, can you tell me the reason?
- Apparently driven problem, your LED desk lamp is the 220 ac mains voltage rectifier, stroboscopic than incandescent bulbs.
- General how long LED desk lamp charging full of learning
- Depends on the size of the battery capacity, average about 1000 ma, 4 to 6 hours is full.
- 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.
- Light flashing, if is to use the adapter, it is possible that the adapter, try out in later.
- This seems not, but can be modified, specific how to operate, can go to the shenzhen LED lighting look at technical articles on net
