Q:Folding LED touch lamp generally will be problematic
That should see is a circuit board, or no circuit board, if there is a circuit board, circuit board regulated part of the easy problems, no circuit board switch are problematic
Q:There are several major disadvantages of LED lamps
The adapter generally smaller than LED lights, life is short, the transformer is easily broken
Q:The LED lamp is bad for your eyesight?
SMW there are rumours that the article use LED lights, don't have to talk about blue color change, at the same time, the central 10 sets to show detailed CCTV10 why the advantages of LED lights and LED the lamp that shield an eye can best protect vision video because leds can adjust the color temperature, so you can choose from 3200 ~ 3500 k of warm white LED light source color temperature to reduce the visual perception and the differences of the sun
Q:LED lights it is transistor luminescence is not pure resistance filament bulbs, when dimming voltage changing, the frequency is changing so affect rectifier, sudden high voltage will burn out the LED.
Energy-saving lamps, color rendering index above 80, it has a variety of color temperature. Read a book, I suggest to use 4000 k; High color temperature advantageous to concentrate, but Dazzling; Low colour temperature of concentrate. When reading a book, lamp writes a 1.5 meters, 300-350 lux. So-called energy-saving lamps, is high frequency, otherwise, it is not energy-saving lamps.
Q:LED lamp is broken, put it down, things do
Using the multimeter, diode first gear test lamp bead is damaged. Then find a chip, CL BP OB or PI, NXP driver chip both at home and abroad, and design a constant current drive power supply. Of course also need to look at your desk lamp lights, string and how. General desk lamp is the output of 0.3-0.35 - A, your driver can be designed so that the output current.
Q:sk next incandescent lamp, led lamps and halogen lamps have what distinction, which better
See you use, such as the most used to painting so you can only choose halogen (trichromatic fluorescent lamps also do, but the color is feeling less). General reading, ordinary fluorescent desk work, more money and don't care about environmental problems can buy dc lamp (dc except inefficient and communication than no advantage, use dc, the polar bear's death also have a credit for you!) . Special care about environmental protection and main for night light use you can use the leds
Q:The LED fluorescent lamp color temperature probably how many is the best
In addition, need different environment illumination light color is also different. The household environment, for example, if the sitting room with warm white lighting, can appear dark, stuffy, narrow space; Bedroom, bathroom with cold white light, can appear cold and stiff and lack of emotional appeal again. Dining room lighting light color can require the full performance of food color, too slant blue light of cool color, will look stomach-turning dishes
Q:Desk lamp battery charging why not directly connected light emitting LED lights
See what the battery, the normal pressure drop of white LED is controlled in 2.8 3.6 V, if use lithium battery 3.7 V voltage is a little high, if he does not limit current will be very big, LED immediately to turn the raw materials.
Q:LED rechargeable lamp, can you tell me how long does it take to charge for the first time?
And LED rechargeable lamp used for the first time, should be charged more than 10 hours. LED rechargeable lamp maintenance: LED rechargeable lamp if it is not because the excess voltage or short circuit, usually don't burn out.
Q:Three lights in parallel, and should be how the resistance of the step-down series?
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.
