Q:Is there any flicker in the LED bulb?
Really, the voltage in our home is likely to lead to fluctuations in the LED bulb strobe in public, voltage instability will be more common, but most of the voltage is relatively stable, does not appear large fluctuations, so the strobe is not violent, but the fact is there. Questions raised by the questioner can show that you are observant.
Q:Why can't the voice switch control the time of the LED bulb?
The power of LED bulb is much less than that of incandescent lamp, and the control loop and light bulb of simple sound control lamp are connected in series, and the load is different and the time delay is different
Q:Where can LED bulb be used?
LED bulb is a new type of energy saving lamp to replace traditional incandescent bulb. The traditional incandescent lamp (lamp) of high energy consumption, short service life, in the global resource environment, has been gradually by governments to ban the production, instead is the product of electronic energy-saving lamp, electronic energy-saving lamp while improving the energy saving effect, but because of heavy metals using a lot of pollution of the environment, trend against the environment protection.
Q:Want to buy a few LED bulb, do not know how to identify the quality of good or bad, ask for solution ~!
Power supply must be constant current power supply. This must, do not have that resistance. The constant current source resolution methods, there is no power is apart of a 8 foot IC, if not, no junk to, also not all the IC are good stuff, a famous lighting city have specialized quality of constant current power supply.
Q:LED bulb w can replace 40W incandescent lamp
The standard of luminous flux according to the luminaire is lumen (LM). Incandescent lamps are w 11-12lm per 40w=440-480lm
Q:LED bulb lamp drive power electrical connection, will delay a few seconds before the lamp light, and power creaks, who know what it is!
How many seconds delay? It won't take so long. How many bulbs do you usually soak in 0.5 seconds? A squeaky noise is usually a transformer or inductance whistle, and at least it shows a poor manufacturing process.
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?
With the temperature of the heat sink to judge a lamp is not easy, the domestic aluminum radiator are generally more, for T8T5 will have to see the size of the whole lamp power, the simplest is to look at the weight, the relative materials generally heavier will be better.
Q:How to choose the bulb power?
Obviously, the designer doesn't want the ball lights to work at rated current, but there is a margin, so the light bulb will work more reliably. Because of the constant current source, current of each lamp is not 30mA, but 330mA/13=25mA, of course, the brightness of the lights will be smaller.
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?!
Because LED's normal luminous current is 20MA, and LED has a weak current, it can emit light. According to this source. Maybe your line is just on the zero line. This will lead to a small leakage current flows through the LED lamp.Try offline.
