Q: I buy LED lamp light moving light and shade is how to return a responsibility: Electricity ports poor contact, the ends out then plugged up.

Q: Led and energy-saving light which good? To solve the: 7, the LED lighting technology is not so mature and complete energy-saving lamp technology. In addition, at present, the led is more expensive than price. Warm color lighting good learning? Different from common understanding, the warm color light source because of its low colour temperature, is not good for students to read or write. 5000 k and 6500 k color temperature (cool color light source) is more popular with the students, more suitable for reading, writing, etc to demand higher visual task. To meet the current criteria of classroom illumination condition, relative to the low temperature, high temperature is more advantageous to delay the visual fatigue of primary and middle school students, improve the efficiency of learning, which is consistent with foreign related research results, using ordinary in the middle and primary schools classroom much for high color temperature of the current situation of the fluorescent lamp is also consistent.

Q: What if the led lamp doesn't shine: LED lamp light is usually a lamp is broken, no inspectors according to the following steps to do. 1, before open the LED, measure the power supply voltage, and current through the LED. 2, then open it, each check all key parts: drive or power supply, LED lamp bead, change all the broken lights. 3, find out the failure reasons of LED lamp bead, if flow, immediately minish the drive current. Check whether the drive is defective, also want to find out the reason, can the trim, can't repair the replacement

Q: LED rechargeable lamp, battery voltage is how many v?: The working voltage of LED (light-emitting diode) on different materials are different. Ordinary do remind instructions with phosphorus gallium arsenide material in between 1.55 V - 1.85 V; Gallium nitride material in 1.85 V - 2.15 V, the LED is red, green, yellow, orange glow (double color LED a variety of colors to choose from. General working current is very small, about 5-10 ma (0.005 0.010 A) A -- -- -- -- --, the brightness is not very high, can not be used for lighting. Using is a kind of super high brightness LED flashlight, its working voltage is higher, generally 3.35 V - 3.65 V, working current is relatively large, at 30 ma -- -- -- -- -- 50 ma, high brightness. Above is reproduced, the following is what I write. You can also in the baidu search is known here.

Q: LED lamp, lens type and light type which good,: If it is put on the edge of the desk lamp of the head of a bed or lens would be better, but before problem lens design is reasonable, no spot. Planar light light is scattered, suit to put on the desk, the hope can help you. You have to actually desk lamp is the key to no stroboscopic, this to the injured eye

Q: Need to solve the problem of the LED light flashing: Confirm your 12 v charger ac components have? Using the multimeter, exchange files have measure ac voltage, and you want to confirm what you said is the lamp bead board was flashing (that is specialized flashing LED lights with IC control board).

Q: Led desk lamp suits, how many watts of the led lamps are very high colour temperature: The power of 1.6 W as small obviously a big gap compared with the fluorescent minimum 11 W. Now you are in the best tube is short of the brightness. Its advantage is to save electricity, if you want to look good will have to buy a 7, 8 W above.

Q: Hurry, common desk lamp is ac or dc output, and energy saving LED lamp?: Common desk lamp is communication, voltage 220 v, 12 v in the majority; Most energy-saving LED lamp is a dc output voltage international big brands is 9 v, domestic brands generally 12 v.

Q: Led rechargeable lamps how to charge: Lead-acid battery charging requirement after filled with a floating time state, with the changed the user capacity and circuit design is difficult to grasp, because charging time short, filling is too long to form a rechargeable battery life shortened, theonly low-grade products without charging protection circuit, only carefully study the product description. A rough judgment

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
