Q: LED bulb with what type of LED beads?: The LED bulb is mainly white and warm white two colors are white, the temperature is generally 6000-6500K color, the color of the sun light at noonWarm white temperature is 2700-3000K, yellow, similar to the sunset color temperature.

Q: LED bulb lamp drive power electrical connection, will delay a few seconds before the lamp light, and power creaks, who know what it is!: Power supply has noise, it is the design of transformer, winding, the design of switch power supply.. Engineering reference..

Q: Can the bulb's true life reach 30000~50000 by LED?: The theory of the life of LED is one hundred thousand hours, this is not true; but the LED life is far less than one hundred thousand hours, only ten thousand hours, which is currently the most industrialized production of long life; because the quality of the LED part of the core - epitaxial wafer has not reached the ideal state, there are many problems to be solved, such as reducing the dislocation the density of epitaxial film, high quality P GaN preparation etc.

Q: How to choose the bulb power?: If it is household, choose the separation side, because the separation type is relatively safe, easier to pass through safety regulations, but the cost is relatively high, but suitable for home use.

Q: LED what kinds of screw bulbs are there?: There are E14, E27, E40, B22, LED bulb, only these screwsThe most commonly used are the E27 sizes, and the E14 is used in small bulbs, such as refrigerators and E40, for larger power.

Q: What are the driving IC used in LED bulb?: The analysis report shows that nearly three years, the domestic market share of LED lamps will increase from 5% to about 20%-30% can be seen, LED is now the need to walk into the homes of ordinary people, so we need to control the cost, cost is the main driving power LED lamp and a shell, a power driven material faster BOM province can let the promotion of LED. As the LED lamp has the characteristics of energy saving and environmental protection, the state has also subsidized the product accordingly.

Q: I want to ask for high power LED bulb lamp wire inexplicably broke, and in large quantities. Is the quality of the lamp?: Or if there's a problem with the process, just zoom in and see!

Q: LED can the bulb be used in the bathroom?: of couse Yes, but LED kitchen and toilet light is recommended

Q: Is it possible to manually weld LED bulb bulbs?: You can ignore the effect of heat conduction and thermal grease, solder is better, I was doing a lot of tests, the thermal conductivity of thermal grease is about 1.2 to 2, aluminum more than 300, thermal grease just to fill the bottom of the LED and the aluminum substrate contact surface gap, you don't fill gaps don't hinder it the normal contact with the aluminum substrate at the bottom of the LED, will be lost, and the use of thermal grease you for about a year will have to replace the thermal grease, only unscrupulous vendors will deceive others say I added thermal grease, heat conduction effect is not fully qualified, in fact, for a long time, the potential will LED light spot the chip inside the loose because of the long-term high temperature, causing the current growing, until completely off

Q: What brand of LED bulb is good in quality?: View brightness. Incandescent lamps usually only talk about wattage instead of lumens, but LED bulbs can count in watts, but wattage does not represent the number of lumens due to the continuous development of LED's luminous efficiency.
