Q:Led what's the flash of the bulb?
Should be the cheapest LED bulb, the lamp driver is not a constant current source, in the voltage fluctuations will appear flash.
Q:60W how many lumens and how many W LED bulb does incandescent bulb replace?
100lM/W LED bulb, 4-5W can be replaced. If it is white 4W can be, if it is warm white (yellow light), preferably 5W, mainly human eye feeling, white light than Huang Guangliang.4-5W LED bulb, equivalent to 12-15W energy-saving lamps
Q:LED what are the bulb screws?
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:Will the power of the LED bulb grow longer and longer? Why?
Voltage problems, as well as unstable factors.Long time no change, should
Q:LED how does the bulb return electricity?
What is reflow? Never heard of it. I am a lighting technician
Q:What's the difference between a glass cap for a bulb and a PC hood?
ProcessabilityMachinable, blister, special-shaped processing PC easier.
Q:What does "A19" mean in LED A19 bulb?
I'm studying too! There's a problem for everyone to discuss
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 LED price of aluminum alloy 3W is probably about 30.
Q:How to identify Ic constant current LED bulb?
Another is to destroy the bulb and see the power inside the bulb. Not a constant current power supply, only some capacitors, diodes, resistors, and the like. The constant current drive, in addition to the diode electrolytic capacitor, there is a 6 foot IC and a triode, there is a high frequency isolation transformer. To make it clear, you can take a look at it.
Q:What is the 15 Watt lumen of the LED bulb?
The chip is better, but it's also 80lm/w's light effect, so the 15W flux is 1200lm's.. The chips are even lower
