Q: Ordinary lamp LED bulb can?: It should be clear, your point is before the lamp lights inside what, from the rectifier? LED bulb is mostly with drive, if there is no self rectifier lamp light, the best is the bulb is directly connected to the E27/E14/B22 lamp, LED lamp or light source has a good energy saving effect, mercury free lead-free, no stroboscopic, energy than traditional fluorescent lamp 80%

Q: LED how does the bulb return electricity?: A 0 ohm resistor with a large point on the negative electrode

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: What are the driving IC used in LED bulb?: MT7930, LM3445MM do bulb bulb, the effect is also ok.

Q: What is the AC voltage of the LED bulb?: 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 3-5 times energy-saving lamps.More healthy: light evenly, no strobe, no glare, no UV and infrared.More environmentally friendly: no mercury vapor, harmful substances 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: 60W how many lumens and how many W LED bulb does incandescent bulb replace?: General household enough, if in 10 square meters of housing, installation of more than 10W LED lights, brightness is too good, if not the study, it is best not to.

Q: Is it possible to manually weld LED bulb bulbs?: As long as the welding technology clearance is possible or OK

Q: What's the difference between a glass cap for a bulb and a PC hood?: Weight comparisonPC specific gravity 1.2,The proportion of glass (usually glass) is 2.5,That is to say, PC is lighter in weight than glass.

Q: Is there any flicker in the LED bulb?: You're right. The strobe is either determined by the driver, the current changes, or the filter doesn't work well

Q: What does "A19" mean in LED A19 bulb?: A19 is the European A60: represents the outer diameter 60mm=19/8*25.4=60.325mm, such as the diameter of the A19 bulb. "D=19*1/8", multiplied by 25.4, is the diameter of the bulb in mm units. The source of this formula is the same as the T8 tube: "X" in Tx means that the diameter of the tube is x times 1/8 inches, so the diameter of T8 is 1/8 inches x 8=1 inches, or 25.4mm
