- Q: The LED lamp electrostatic test pass the corrective actions
- See which part of the circuit is broken? Such as the LED part or dimmer IC. So taking measures to more targeted.
- Q: LED dual-mode folding desk lamp on external what meaning be
- LED desk lamp, driving power and desk lamp is divided in two, the vast majority of dc lamp, socket is a circle with a small stick of that kind of, need with the corresponding hollow plug connected to a dc power supply. When you need to use, will drive the dc output of the power plug into the desk lamp of light, and then open the power switch, the lamp light, bright, that's the beauty of dc lamp, this is the external power supply.
- Q: 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.
- 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?
- What you said is likely to be that kind of LED desk lamp, there is a difference between this kind of desk lamp rechargeable batteries, differentiate the probably only from price, twenty yuan is using a small battery, the battery is to increases with the increasing use of filling, generally charge no more than four hours, frequently and filling. Fifty yuan using nickel cadmium or nickel metal hydride batteries, such batteries is to run out of charge again, generally charge for six to eight hours. One hundred yuan with lithium battery, can be used after a period of time to filling filling, no specific requirements, such as the battery's current difference is large, large current will be longer, shorter, conversely in six hours.
- Q: I had had a 20 leds rechargeable lamp, then search the battery is broken, I version removed yourself to make the lamp, can directly use electrical appliances, please start
- The desk lamp of you already can charge (should be 220 v) you can directly with charging power supply should be bright?
- 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: Need to solve the problem of the LED light flashing
- Problem in the connection on the way, I guess you're mistaking 40 simple lamp bead is divided into 10 road, every 4 star all the way, so directly in parallel on the 12 v is? First answer me how do you connect again to teach you.
- Q: Led lamp, good point light source or surface light source
- Desk lamp to see is to choose lamp holder types use the bedroom or in the study, the study USES led is very good choice, monochromatic light color cold light source, can help clear your mind to learn reading; But the bedroom use or suggest using incandescent lamp, mild color, adjust the mood to sleep. Get to the point, it is recommended to use surface light source, light area is larger, help reading and prevention of myopia.
- Q: When did you buy? If it is just bought, suggest you use first photoelectric charge again
- When did you buy? If it is just bought, suggest you use first photoelectric charge again
- Q: LED small desk lamp, found that the charging indicator light is not bright, or bad?
- Since it is new, then to find businesses, can ask how to use correctly.
