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:How to identify what the real eye lamp?

According to statistics, the workers engaged in copy writing and many of the students, many patients are caused by improper use desk lamp of eye myopia. In advocate "energy saving, health, environmental protection" fashion today, LED the desk lamp that shield an eye become the first choice for many consumers buy lamp. x0d Angle LED the desk lamp that shield an eye to consider the desk lamp that shield an eye is the most fundamental essence, is to solve the problem of stroboscopic x0d the desk lamp that shield an eye eye principle of be particular about is adopted to reduce the number of stroboscopic electronic ballasts, 50 hz ac electrical signal can be transformed into stable amplitude of high frequency signal, and thus can reduce the eyes when using affected by light stroboscopic. Electric light source experts of a stroboscopic analysis: light stroboscopic indeed can cause eye discomfort, such as ordinary kept flashing fluorescent lamp generates 100 times per second, cannot adapt to people's eyes, but when the lights flashing the number of times per second increases to a certain extent, imperceptible to the naked eye, the eye will be relatively comfortable. And it cannot fundamentally solve the problem of desk lamp no stroboscopic, and as a LED the desk lamp that shield an eye, using the latest electronic constant-current technology, combined with dc power supply, eliminates the current constantly changing, thus fundamentally eliminating the stroboscopic. x0d with good quality of the lamp that shield an eye light close to natural light x0d

Q:Charging forgot to turn off the switch, directly inserted, and then not bright,, but the charge will bright lights.. Bulb burned out or what? Can you take?

Due to the charging voltage is higher, it is burnt out, LED lights in after the LED can also be used, but more troublesome.

Q:LED the desk lamp that shield an eye eye really?

Use eye, as long as the light is a kind of damage, the difference is only the size and the third, of course, is impossible, with the eye is not light lamp of choosing a cross-eyed least damage is completely necessary, by contrast, leds regardless of the effect, efficiency, and a huge step forward in principle, is the most close to natural light in all the light source of human invention. It is believed that you have to know. Just led lights there are pros and cons, now led market good rust is not neat, the size of the brand, the price have jet lag for a few times, but as long as it is more adept or understand led people have a better method, is a choice of using high power led lamp bead light is guaranteed!!

Q:The LED lamp how to realize the function of adjustable brightness and color temperature?

Simple dimming can be concatenated in the LED lamp bead loop resistance, change the current, can adjust the brightness, better with adjustable brightness of PWM pulse width adjustment, circuit is more complex. Color temperature seems to be no commonly, by LED lamp bead characteristics (fixed) materials and manufacturing has decided, unable to adjust.

Q:Desk lamp battery charging why not directly connected light emitting leds, but to a diode, the diode have what effect

If animal nickel cadmium or lead nickel-metal hydride batteries, their monomer voltage is 1.2 V, then use two voltage is not enough to push the LED, with three high again, then to string a diode to the voltage

Q:LED lamp, adjustable light, new to buy less than a week; Strip, it took more than 4 years. This morning on the strip, light will flash. To strip of the others will be fine. But the same old jack plug in the computer, but everything is normal, but the strip will issue "hissing" sound. Supposedly the lamp power is smaller than a computer, this is how to return a responsibility? I think baidu has said strip contact.

You have the phenomenon of poor contact strip inside It is ok to exclude poor contact

Q:Led desk lamp suits, how many watts of the led lamps are very high colour temperature

Low-grade products in pursuit of profits must use more bad of the tube, and high color temperature, color rendering dazzling. Choose 3000 k is a little yellow, not bright. So the pipe with around 5000 k

Q:How to distinguish whether the led lamps and lanterns glare, is there a standard?

Glare can be divided into disability glare and arrow glare. Who reduce eye glare called a disability glare, it will be Reduce the visibility of the visual object, but not necessarily produce uncomfortable feelings; Who make the person produces the feeling of displeasure glare is called no Comfortable and glare. Cause glare of led lamps and lanterns has the following four major factors. (1) the light source brightness factor: the higher brightness, glare, the more significant. (2) light source location factor: the closer it gets to the line of sight, glare, the more significant. (3) the light source appearance size and number of factors: the apparent area, the greater the number of light sources, the more the glare, the more significant. (4) the surrounding environmental factors: environment brightness is dark, eyes adapt to lower brightness, glare also becomes more significant. Dazzling light not light, but for the concept of lamps and lanterns. Leds - t8 fluorescent lamp has been rise, are alternative Fluorescent lamp market, due to the lamps and lanterns is ready, can't change, leds - t8 fluorescent lamp needs to ordinary fluorescent effect Fruit near, thus formed the concept of glare. Anti glare products, need to consider the brightness of the led, led between the row Cloth, spacing, the led itself to the distance of the optical cover, the shape of the optical cover, light transmittance, etc., rather than simple Shell or configuration problem.

Q:LED lamp, lens type and light type which good,

A planar light well. Here's why: surface light illumination uniformity, no glare, not dazzling. Lens type is suitable for use in lighting, such as shops, clothing stores, pictures, advertising board and so on, should not be used for the table lamp with eyes, long time.
