Q:How bright flowers LED desk lamp, good quality
Generally see lights with LED has obvious advantages, to buy the children learning advice to wait to buy the LED lamps and lanterns, to miss the rush stages will be better. In fact, all sorts of lamps and lanterns are the national standard, as long as accord with a standard can be used.
Q:The service life of LED lamps and lanterns is true?
Theory is a 30000 h - 50000 - h (semiconductor diode). 1. The chip encapsulation (not the same environment, affect the life. And the light bulb how to low the situation is not possible, this is a standard) 2. The power drive power supply (electronic products, general is 2 years,) 3. The lamps and lanterns, the whole life is a long time, generally 2 to 3 years.
Q:Home to buy led desk lamp is broken? Can someone fix it?
First, let people to understand together what is LED lamp, LED lamp is with leds (Light Emitting Diode), namely, the desk lamp of light emitting Diode as light source, LED is a solid-state semiconductor devices, it can be directly put DianZhuan into light. LED lamps mainly on my desk, there should be seen! The led lamp is broken? First, what kind of degree, do you want to look bad if only desk lamp light bead is broken, not bright, it is resistance there is a problem, this will need to change the lamp bead and resistance. As for what's in it? This will still get the special repair shop to repair. If if is changing lamp bead, at the time it was bought on the manual of desk lamp, lamp bead size and style are consistent, avoid safety accident. Led lamp is broken, there are one thousand emergency, they cannot rule out, but they can use opportunely coup to solve one by one. Led desk lamp is broken what can I do the second case is all of the lights, less bright than before, that means that may be a desk lamp internal battery is broken, need to replace a battery at the same time also check link and the power of the thread is broken, if it is a wire is broken, change it, this is unable to repair, no equipment, and can't find the repair method, the solution only replacement. Under the condition of led desk lamp is broken what can I do, actually is a small matter.
Q:The problem with LED charging lamps?
Now technical innovation, new types of LED lights are super save electricity. Filling desk lamp I felt at least on a 12 hours in order to be qualified, otherwise how enough
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 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: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:Light flashing, if is to use the adapter, it is possible that the adapter, try out in later.
Because incandescent lamp and electronic energy-saving lamps in People's Daily use still occupies a very high proportion, in order to reduce the waste, LED lighting manufacturers must develop in accordance with the existing interface and habits of the people are using the LED lighting products, make people don't need to replace the original traditional lamps and lanterns pedestal and lines can be used under the condition of a new generation of LED lighting products. So the LED ball steep light was born. LED ball steep light used the existing way of interface, the screw (E26 / E27 / E14, etc.), pin (B22, etc.), and even to accord with the habits of people to imitate the appearance of the incandescent light bulb. Based on LED light-emitting principle of unipolarity, designers did change in the lamps and lanterns of the structure make the LED ball steep light light distribution curve of the basic point source of convergence with incandescent bulbs.
Q:LED desk lamp, the USB interface, security, will the light bulb suddenly blow up
Absolutely safe. The LED is solid, there is no gap, not like a normal light bulb, there is no fry
Q:How many watts of 10 square meters of the bedroom with led bulbs Warm white or white
10 square meters room are you in a light bulb or multiple light bulb? If a light bulb base lighting 9 w, 7 w must be bright enough. Since this is the bedroom must have table lamps, bedside lamp and so on as auxiliary. Tmall ef led bulb is good, 9 wled bulb is equivalent to 20 w energy-saving lamp brightness
