A: Minimum 2 years
- Q:What brand of LED bulb is good in quality?
- See shape. Incandescent bulbs are usually pear shaped, so the bulb should be pear shaped. That's easy to do. But incandescent lamps are all glass products, and because LED requires heat radiation, aluminum alloys are usually used as housings, because of their low cost, easy processing, and good thermal conductivity. The size of the aluminum shell determines the heat dissipation and also determines the life span.
- Q:LED bulb is broken. The luminous patch is not bad. Can it be made into USB lamp?
- LED bulb is broken. The luminous patch is not bad. It can be made into USB lamp.LED bulb is usually a series of LED series, and then parallel, generally about 12V.Single chip LED generally rated voltage at 3.0V~3.6V, USB, output voltage of about 5.0V.Look at the LED in the LED bulb. Several LED are connected in series. Several groups are connected together, and then the voltage is estimated.Then the power of the bulb is divided by the voltage of the LED bulb to calculate the required current.Select the appropriate LED drive circuit. The average USB output current of the computer is only 100mA~500mA. The power is not enough to make the LED light to normal brightness, or it may damage the USB interface. It is better to use the USB charger interface.Light emitting diodes, referred to as LED. Made from compounds containing gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N) and so on.
- Q:Are there any differences between negative ion bulb and LED bulb?
- Negative ions should belong to traditional lighting technology, LED is the latest lighting technology
- Q:LED what kinds of screw bulbs are there?
- LED bulb adopts the existing method of incandescent lamp interface, the general screw is E27E14E40 (three). E for screw holes, figures for size, diameter, size. The most commonly used are the E27 sizes, and the E14 is used in small bulbs, such as refrigerators and E40, for larger power.
- Q:LED bulb lamp. Is there a good drive or no drive? Is the lamp of good or integrated?
- The cost is too high, the latter is better than the former, with long service life, there is a need bulb welcome to Taobao fry and sales of professional manufacturers of high power LED lighting lamp.
- Q:Led the bulb is flashing. What's wrong with it? How do you fix it?
- The driving power inside is broken. If there is basic electronic knowledge, replace the inner capacitor. Most probably the electrolytic capacitor is broken.However, the cost of the bulb products is relatively low, and the cost of the repair is greater than the cost of the change.
- Q:Choose which light bulb LED bulb is the healthiest
- The two said warm light, power, color temperature and so on have little to do with health
- Q:Will the LED bulb, T8, T5 lights, radiator lamps, is the hotter the better? What's the regular temperature? What are the common heat release materials? Specifications?
- Of course, the hotter the better, because for the same material, the hotter it is, the more heat the LED chips use, the less good the quality of the chips. The thermal characteristics of lamps is mainly to measure the junction temperature of LED Shenglai rather than the temperature of heat sink. Aluminum is commonly used in heat dissipation materials.
- Q:How does the LED bulb go with the power?
- voltage range as long as the 36V can be achieved, for example: voltage range 24v-80v is very good,
- Q:How to identify Ic constant current LED bulb?
- Hello, LED market is now very confused, this problem is the use of LED lamps of the users are more concerned about the problem, the so-called IC constant current drive power refers to the LED lamp (commonly known as the transformer) with a constant stream of multifunctional IC chip, the IC is generally 5-8 feet (depending on the model and decision scheme), role is to ensure that the current through LED lamp is controlled in a relatively constant parameter, ensure the long-term stability of LED lamp work at constant current. When the input or output voltage is changed, the current through LED remains constant, so the constant current IC of the LED light stability and service life is directly related to the IC also includes internal short circuit protection, overtemperature protection function of open protection etc.
