- Q:Led energy-saving lamps are easy to break

- LED lamp standard current to 20 ma, just meet this condition
- Q:The led lamp low-grade why current sound
- You couldn't hear the sound of the single. Current should be the current instability caused by electric magnetic vibration. High-grade didn't work in a very stable power supply should be no broken (continuous waveform, basic), when low, the power output is lighter, and load lighter, leading to power cannot be stable and continuous work, appear discontinuous phenomenon. When the pulsation frequency into the region of the human ear can identify when they heard the sound. In general should be the power source design is not perfect, if you want to change, if you have a basic knowledge, from the perspective of the feedback loop.
- Q:LED lamp circuit of current more conference appear what problem
- Will first fever, if it is too big, can burn out directly. On the issue of the lights, string, and, have a plenty of string and share
- Q:Of tubes is said to be good, and some say good leds, which is really good

- Most can't plugged directly, that kind of desk lamp without charging control circuit, as long as you don't put it down from the socket, I have been to the battery. The lamp general charging about 10 hours, evaporation of charging can lead to lead battery, the electrolyte (dilute sulphuric acid) concentration increases, serious shorten the service life of batteries.
- 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.
