FAQ

Low voltage LED desk lamp belongs to the scope of 3 c certification

See were independent of a body or power supply Independence is the power to do 3 c lamp don't have to do

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

That you the simplest way is to change the battery. Or don't you phone charger, and then put the head of the line across the electrodes of LED lights from you, then you can use electrical appliances, is the voltage peak

Led and energy-saving light which good? To solve the

3, energy-saving lamp power consumption is too large. White LED power consumption is only 1/10 of incandescent lamp, energy-saving lamp of a quarter. 4, energy-saving lamps, easy damage, short service life. Led lights, longevity life can reach more than 100000 hours, can work at high speed. Energy-saving lamps if frequent start or shut off the filament broken will be dark soon. 5, a single LED low power, and energy-saving lamps to achieve the same brightness require multiple parallel. 6, the led light color rendering index is low, under the led light display color no real energy-saving lamps

What if the led lamp doesn't shine

LED the working voltage is usually about 3 v, the circuit generally take three or six string a string, each string of working voltage is 12 v or 24 v, unwrapped desk lamp, look at the inside of the circuit can be known. If is the transformer working have to be replaced,

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

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

What is your 6 v battery batteries? Small battery (battery)? 10 v charger to see what the battery charger, if the battery can work with, if nimh electricity or lithium electricity will reduce the voltage. How much is the pressure light bulb? It is best to parallel, serial word broke a are not lit up. Add how much resistance depends on what you use the lamp, or led. The dimming added potentiator current limiting. How to do is very simple, still with the figure? Charger and battery, lamps (and) series of potentiometer. If it is nickel metal hydride batteries can't do, for a long time will seriously affect the battery life in charging status. The more complex.

Do leds have ultraviolet radiation

LED is characterized by single band, the wavelengths are generally above is 390 nm, uv to less than 380 nm, so there is no uv components

The led bulb loaded on the adjustable light lamp is broken

If don't use without support, mount or will be relatively easy to burn out.
