Q:In a bulb, the ambient temperature of the LED is LED, the temperature of the air in the bulb, or the temperature of the aluminum substrate

LED work environment refers to the external work room temperature, LED lamps also have a working temperature, general LED lamp in the case of work, the external temperature is below 65 degrees is normal.

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:LED can the bulb be used in the bathroom?

Yes, the bulb may is waterproof and dustproof with protection

Q:Why is 3W's LED plastic bulb so cheap on the market? Is there any drawback to the price difference between aluminum and aluminum?

Now the market LED lamps quality uneven. LED lamps need constant current and constant voltage drive to be durable. The cheap 3W LED plastic bulb power supply is only the drive of the resistance capacitance pressure drop. Drive rank: 1. constant current and constant voltage drive. 2. constant current non constant voltage drive. 3. constant pressure and no current drive. 4. resistance capacitance pressure drop drive (resistance capacitance voltage drop is the worst and cost is the cheapest)

Q:Will the power of the LED bulb grow longer and longer? Why?

The LED bulb does not become more powerful for extended periods of time.

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:LED what is the plastic shell of the bulb? What plastic material is better? What do you need to pay attention to?

There are several good LED ball bubble, which with aluminum cooling. Relatively new appearance.

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 to choose the bulb power?

If the public is not high, the quality requirements, and to control the price, you can choose non isolated, because it does not require isolation transformer, so the cost is relatively low, but the aluminum substrate voltage requirements is relatively high, otherwise there may be charged radiator, and still light outside is not very beautiful.

Q:What's the reason why LED bulb gets a lot of heat?

If the radiator is about the same size, it's not nice to touch the low temperature, because the heat accumulates in it and doesn't come out. The.LED lamp doesn't last long
