FAQ

How many volts 4 w power led desk lamp

Depends on what kind of, have 220 v, also has a charging V6, 12 v.

Are LED lights compared to dc lights?

We use alternating current (ac) is a stroboscopic, is 50 times a second, but should not be visual. If you buy the dc LED lamp, there is a power saving advantages of high brightness, it can be said to be no stroboscopic, by using dc. You can buy it now, is this your smart move.

Home to buy led desk lamp is broken? Can someone fix it?

Led desk lamp is broken happened to do a fourth most often is the lamp not bright, the bright part is divided into light, or is not all bright, if the part is not bright, leads to such a situation has a lot of, or the circuit in the process of transportation, short circuit, or the voltage lead to light bead is broken; Or transmission in the process of welding is not good, if so, in the case of cut off the power the lights bead is not light that were removed, ready to two-way plug into two line.

Led rechargeable lamps how to charge

Try every half hour after 2 hours filling light observation (do not charge while light), plus fruit no longer increases should be full of light is the brightest and desk lamp brightness, floating charge time same again can

How to distinguish whether the led lamps and lanterns glare, is there a standard?

Glare can be divided into disability glare and arrow glare. Who reduce eye glare called a disability glare, it will be Reduce the visibility of the visual object, but not necessarily produce uncomfortable feelings; Who make the person produces the feeling of displeasure glare is called no Comfortable and glare. Cause glare of led lamps and lanterns has the following four major factors. (1) the light source brightness factor: the higher brightness, glare, the more significant. (2) light source location factor: the closer it gets to the line of sight, glare, the more significant. (3) the light source appearance size and number of factors: the apparent area, the greater the number of light sources, the more the glare, the more significant. (4) the surrounding environmental factors: environment brightness is dark, eyes adapt to lower brightness, glare also becomes more significant. Dazzling light not light, but for the concept of lamps and lanterns. Leds - t8 fluorescent lamp has been rise, are alternative Fluorescent lamp market, due to the lamps and lanterns is ready, can't change, leds - t8 fluorescent lamp needs to ordinary fluorescent effect Fruit near, thus formed the concept of glare. Anti glare products, need to consider the brightness of the led, led between the row Cloth, spacing, the led itself to the distance of the optical cover, the shape of the optical cover, light transmittance, etc., rather than simple Shell or configuration problem.

How many watts of LED3 is equal to the ordinary energy-saving lamps

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.
