- Q: Led the desk lamp that shield an eye how to choose?
- No stroboscopic, this is the most critical. Color rendering index above 80 (the higher the better).I hope you can help me
- Q: What led small desk lamp general battery
- Is generally use USB, or the normal power supply You'd better use the rechargeable batteries, battery both environmental protection and use
- Q: Led charging folding desk lamp it can directly plug
- Charging desk lamp is LED (Light Emitting Diode) the desk lamp of the light-emitting Diode as Light source, with lithium battery and USB charging function, the LED is a solid-state semiconductor devices, it can be directly put DianZhuan into Light.
- Q: I'm doing a LED desk lamp, can be through the outside light intensity automatically adjust the brightness of LED, using PWM technology, how to do excuse me
- Using PWM technology, you need to use single chip microcomputer output a certain duty cycle of square wave, the duty ratio, the greater the more bright. Also need to use sensors to collect light intensity, the establishment of a model, to achieve automatic brightness adjustment.
- Q: LED lamp stroboscopic serious, can you tell me the reason?
- Is zero, because ac 100 times per second of voltage is zero, if simply step-down rectifier circuit, or filter capacitance is too small, through the LED current is 100 times per second interrupt, LED is a semiconductor light emitting, reach nanosecond, response time and tungsten by electric heating filament reach the state of incandescent light emitting, filament cooling speed is about tens of milliseconds, you can turn on the LED desk lamp to see the inside of the circuit.
- Q: What are led lamp accessories
- Base, supports, lamp cover, LED lighting slab, connecting wires, switches, + 1, 220 v direct plug-in: transformer, rectifier steady pressure plate. + 2, USB plug type: USB cable, drive power panel
- Q: How to maintenance of led desk lamp filled in no electricity
- It seems is the switching power supply, circuit board above and have a look. You understand the welding and the multimeter test? If you don't send repair shop
- Q: Led energy-saving lamps are easy to break
- Lamp bead itself long life, but if private purchases, it is important to note that the quality of power supply, if the power supply is normal electrolytic, materials and more bad, can be used for a year is pretty good. When be being bought so little can distinguish good or bad, do not blindly pursue low price, or we will lose out.
- Q: With 10 v charger with 6 v rechargeable batteries used at the same time, that is used when mains mains, there is no mains automatic conversion electric battery. Three light bead is in series or parallel good? Add how much resistance? Step-down to to the charger? If I want the dimmer, should how to do, had better have circuit diagram
- 6 V battery should use free WeiHuXing 4 ah lead-acid batteries, the charging voltage should be 7.2 V ~ 7.5 V, and to have full automatic protection function. Can't use 10 v charger. Don't know what LED lights you choose? The working current? Positive pressure drop? These have a connection and choose the series resistance and the dimming.
- Q: LED lamp wattage? How much is the smallest biggest respectively?
- The main characteristic is to save electricity, under the condition of the same brightness, than the ordinary energy-saving lamps save electricity more than half
