Q:LED what kinds of screw bulbs are there?

LED bulb is the appearance of the shape of the bulb - people have the habit of spherical internal light source is selected for LED lamp. With all the advantages of LED lamps: 1, energy saving, environmental protection; 2, long service life; 3, no stroboscopic, green.More energy-saving: LED lamp energy consumption is energy-saving lamp 1/4, incandescent lamp 1/10Long life: LED lamp life of up to 50 thousand hours, life expectancy is 5-10 times energy-saving lamps.More healthy: light evenly, no strobe, no glare, no UV and infrared.More environmentally friendly: no harmful substances such as mercury can be recycled to protect the green earth.Full color change: rich colors, vivid and delicate patterns and effects can be displayed.Installation convenience: simple installation, can replace incandescent lamp directly, maintenance cost is extremely low.

Q:Where can LED bulb be used?

The surface of the lamp body is sprayed with high quality heat radiation paint, that is, the heat dissipation efficiency is ensured, and the appearance is elegant, and the utility model provides better guarantee for the low temperature work of the product.

Q:LED bulb w can replace 40W incandescent lamp

I am engaged in the LED drive industry, not very professional, and I hope to help you.About brightness and energy saving comparison,1W LED=3W CFL (energy saving lamp) =15W incandescent lamp3W LED=8W CFL (energy saving lamp) =25W incandescent lamp4W LED=11W CFL (energy saving lamp) =40W incandescent lamp8W LED=15W CFL (energy saving lamp) =75W incandescent lamp12W LED=20W CFL (energy saving lamp) =100W incandescent lampBecause the company uses the light quality is not a reason, so this is not absolute.

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?

One point price must be a sub goods, this is wrong.Plastic cheap because the cost is relatively low, can not talk about grades, plastic LED mainly for the application oriented,

Q:What's the cause of the noise during the aging of LED bulb bulbs?

The power supply LED bulb using miniature low power switching power supply, switching transformer due to loose, and the switching frequency did not avoid the audio area, it will beep.

Q:What brand of LED bulb is good in quality?

What brand of LED bulb is good? LED bulb has replaced the ordinary fluorescent lamp and incandescent lamp gradually, with the market demand is more and more big, and the production of the LED lamp threshold is very low, so a lot of small family workshop also began assembling production of LED lamps, the technical content is low, without testing and certification of products, also began to circulate on the market.

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:Detailed description of LED bulb lamp

A bulb can be said to be the highest cost of the driver, not the driver, light is not bright. And for the quality of a ball bubble

Q:Choose which light bulb LED bulb is the healthiest

For home use, you can select LED bulb below 8W, with a color temperature below 3500K

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.
