Led Bulb Light

Q: LED thread specifications for bulb bulbs?: Ordinary home E27 screw lamp ah, there is a need to ball on Taobao, art night lights, E27, E26, B22, E27 specifications in the majority! E27, E14, G10, E40 are more commonly used Oh!

Q: What's the reason why LED bulb gets a lot of heat?: If the radiator is about the same size, it's not nice to touch the low temperature, because the heat accumulates in it and doesn't come out. The.LED lamp doesn't last long

Q: Ordinary lamp LED bulb can?: As long as the inside of the interface is the same, for example, the E27 interface (ordinary spiral, that can be installed energy-saving lamps) installed there is no problem, LED bulb is now a lot of 110V-220V high voltage power supply, so the stability is very strong, the key is to save electricity, saving seventy percent than the energy-saving lamp, no effect, ease of use.

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?: Now the market LED lamps quality uneven. LED lamps need constant current and constant voltage drive to be durable. The cheap 3W LED plastic bulb power supply is only the drive of the resistance capacitance pressure drop. Drive rank: 1. constant current and constant voltage drive. 2. constant current non constant voltage drive. 3. constant pressure and no current drive. 4. resistance capacitance pressure drop drive (resistance capacitance voltage drop is the worst and cost is the cheapest)

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

Q: What are the requirements of the LED series inspection specification for bulb bulbs?: Dielectric strength: electrical endurance test (resistance test) followed by insulation resistance test. During testing, the following AC voltage is applied at the specified position 1min. Type HV (220~250V); 4000V (RMS), BV (100~120V); 2U (rated voltage) +1000v.

Q: What's the reason for the LED bulb strobe?: Common causes and treatment of LED light flashing:Generally, the human eye can detect light flashes with frequencies up to 70 Hz, which are not sensed above this frequency. Therefore, in LED lighting applications, if the pulse frequency appears below 70 Hz low-frequency components, the human eye will feel flashing. Of course, in specific applications, there are a variety of factors that may cause LED lights to flicker. For example, in offline low power LED lighting applications, a common power topology is an isolated flyback topology.

Q: What are the characteristics of LED bulb?: Less power consumption, a 5 Watt LED bulb, equivalent to 40 watts of ordinary incandescent.

Q: What does the LED bulb patch mean?: In order to obtain high power LED light source, high brightness, the manufacturers to power direction in LED chip and package design. At present, the LED package can withstand W power has emerged. For example, Norlux series of high-power LED packaging structure for the hexagonal aluminum plate as base (the conductive) multi chip combination. The base diameter of 31.75mm, light emitting area is located in the central part, a diameter of about mm (0.375 * 25.4), can accommodate 40 LED tube core, at the same time as the aluminum heat sink. This package uses conventional tube core combination of high density packaging, high luminous efficiency, low thermal resistance, high in light output power flow under high electric. Is a kind of promising LED solid state light source.

Q: Led what's the flash of the bulb?: I don't know how you flashed this light. Did you flash or turn off the light before you left it?. If the lights are off, you should ask the electrician if the line on the switch is connected or not. If the switch is connected to the negative line, it will flash. If it is open after the flash, mostly driving power problems
