- Q:Why can't the voice switch control the time of the LED bulb?
- Current problem. The current is too weak. You don't have to use an electric meter to see if you can work properly without a light bulb. Change the timer switch.
- 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 difference of power factor is large, and the resistance capacitance pressure drop is below 0.5 PF. Constant current and constant voltage drive PF over 0.9. The resistance drop pressure is really attractive, after all, the price is there. The average person doesn't understand the look.
- Q:Will the power of the LED bulb grow longer and longer? Why?
- Could you tell me the measurement method? - how about the side current and voltage? Or, whether direct measurement of active power under mains power supply?Also, can you tell me the circuit of LED bulb? DC power supply or AC power supply? Constant current module drive or RC current limiter? If the power supply is 12 volts low, is the resistor only current limiting?I feel something doesn't make sense......In one case, the longer the duration of the LED bulb, the greater the power:In some advanced LED bulb bulbs, an anti impact "slow start" circuit is added to the design, and a NTC (negative temperature coefficient) resistor is incorporated into the LED power supply circuit.Because of the larger resistance of NTC in cold state, the current of LED is smaller and the power is relatively small;With the use of electricity LED bulbs, NTC resistance temperature gradually increased, the resistance is reduced, the current of LED is also increased, so the power LED bulb also increases, temperature stability, until NTC resistance unchanged so far.
- 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:What brand of LED bulb is good in quality?
- View brightness. Incandescent lamps usually only talk about wattage instead of lumens, but LED bulbs can count in watts, but wattage does not represent the number of lumens due to the continuous development of LED's luminous efficiency.
- Q:LED what is the plastic shell of the bulb? What plastic material is better? What do you need to pay attention to?
- You should say that the bulb of the bulb, usually PC material.
- Q:Are there any differences between negative ion bulb and LED bulb?
- LED bulbs are made by plug-in lights or SMD or high-power LED, and there is no built-in negative ion generator.
- Q:Will the LED bulb, T8, T5 lights, radiator lamps, is the hotter the better? What's the regular temperature? What are the common heat release materials? Specifications?
- If the material with better thermal conductivity, the lamp shell about 60 degrees is best.Reason:1: if the temperature is too high, that your radiator is too small.2: if the temperature is low, indicating that your calories did not lead out. (of course, if the radiator is too large and the temperature is low, but the bulb and tube are too heavy to pass by certification)
- Q:What does "A19" mean in LED A19 bulb?
- A stands for bubble type, A hemisphere bubble19 the numbers in the back indicate the size of the bulb (mm in diameter)On the market LED bulb generally has: hemisphere bubble lamp, A15, A17, A50, A60Global bubble G45, G55, G80, G120 and so on
- Q:LED bulb after the power failure, still glimmer, can last hours or even all day, what is the reason?!
- If it is to continue the glimmer of minutes, the main side is the use of resistance and step-down circuit caused by the normal phenomenon. It's very rare for the factory to use this old model to make LED balls. Circuits that run for hours or all day on the side of the LED bubble are out of order. It's not normal to shine for so long. Now most of the LED bulb is using IC constant current supply circuit, no such situation has emerged.
