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

The first is Aluminum Alloy better heat dissipation, aluminum is relatively high, and made products, together with the positive effect is not the same, in addition, the wick and the circuit there will be differences, this will also affect the application of life and feelings.

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:Led the bulb is flashing. What's wrong with it? How do you fix it?

Q:How to identify Ic constant current LED bulb?

Look at the power supply, there are a few simple electronic and capacitive circuit board, it is not constant flow, cross flow is larger, so understand? Cross flow IC, that is, the meaning of intelligent voltage regulator, so that the LED is not easy, bad capacitor driven LED is relatively easy to damage, easily breakdown, and power consumption than the cross flow
