Q:Is there any flicker in the LED bulb?

First of all, I want to know what kind of LED bulb you bought. Is the LED light source small power or high power?Now on the market LED products, copycat too much, but also a lot of difference between quality and price, because the power output strobe filtering problem. Because the lowest requirements so the power design is very simple, such as shell is small power ball type PVC foam, with isolated power so far I saw several, but the price is very high, and most with the rectifier bridge, several rectifier diode, a capacitor, resistor several complete, low prices. High power type bulb is similar, but the power will be much better, is the constant current source in the output current of the filter is also doing well, there the strobe is low! Finally, the stroboscopic problem is on the power supply, and the power point difference is higher than one or two!!

Q:LED what kinds of screw bulbs are there?

Ordinary bulb is the most common, is a metal electrode which is threaded, so it requires that one electrode when installing the socket contact thread to pick the zero line, the middle dot electrode lamp power. Otherwise, an electric shock occurs when an accidental contact with the exposed metal. Because of this symmetrical way, the bulb can be threaded to fit the socket.

Q:Why can't the voice switch control the time of the LED bulb?

Originally white silk lamp, later replaced by LED bulb, with a light activated switch control, replaced by LED bulb, the lamp does not extinguish for 30 seconds

Q:LED bulb w can replace 40W incandescent lamp

The light efficiency LED lamp better can reach more than 150lm, Hailin's general light efficiency is more than 100 in general can be done, so 3w-5w is almost completely can replace 40W incandescent lamp. Mainly depends on the quality and LED lamp lamp light etc.. The LED Lantern Festival will gradually replace incandescent and fluorescent lights, so more understanding is right. Early use, early save money. I hope there is help for your O (a _ U) O

Q:Ordinary lamp LED bulb can?

Absolutely, without any effect. It can be directly across to look at the opening of several inches.

Q:What is the AC voltage of the LED bulb?

LED lamp or constant voltage drive, generally through the drive circuit filter rectifier, LED bulb bulb AC voltage is generally 220V, power is divided into 3W, 5W, 7W, 8W, 9W, 12W and so on.

Q:Are there any differences between negative ion bulb and LED bulb?

The brightness of LED anion bulb of each LED have good consistency, high color purity, light stability. 1W power, ultra low energy consumption. A variety of light colors are available for you to create a dream like color space. Built in negative ion generator, each cubic centimeter produces 3000000 negative ions that allow you to have a healthy air environment while you own light. Negative ions can effectively remove formaldehyde, benzene, toluene, ammonia, acetone, carbon monoxide, sulfur dioxide and other toxic gases, for your breathing health increased by a solid line of defense.

Q:LED what is the glue between the aluminum base of the bulb and the cooling aluminum?

A lot of sticky glue can live it yourself have not tried to guess 502 good brothers of this kind of glue can be, but do not know good heat resistance and high power LED heat is still very large, if you are a small power never mind

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:LED bulb PC, will the white cover affect the color temperature of the finished lamp?

I've got my lighting engineer to give you a professional answerBecause the light barrier is selective for light waves, that is to say, the transmittance of light at different wavelengths is inconsistent. When the lamp cover is covered, the luminous spectrum of the light source is changed because of the filtering of the lampshade, and the color temperature certainly has certain change.Professional lampshade company should have the detection of the passing rate of different wavelengths. Is your lampshade provided by professional lampshade company?
