- 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:Want to buy a few LED bulb, do not know how to identify the quality of good or bad, ask for solution ~!
- See brightness, whether the luminous uniformity, the back of the heat is good?
- Q:Ordinary lamp LED bulb can?
- No problem, the heating LED bulb is mainly aluminum shell above on the lamp body, a lamp holder will not affect the interface, and the heating temperature does not exceed 60 degrees, and the plastic cap interface at least 160 degrees above the melting point, so is not affected on the lamp interface, you can rest assured that 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?
- One point price must be a sub goods, this is wrong.Plastic cheap because the cost is relatively low, can not talk about grades, plastic LED mainly for the application oriented,
- 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:Led the bulb is flashing. What's wrong with it? How do you fix it?
- There is a drive power failure, and if you do not electronic repair ah, it is recommended to return directly to another driver, generally have 1 years warranty period
- Q:What advantages does LED bulb replace energy saving lamp?
- The response time is fast, the energy saving lamp is millisecond, and the LED light is nanosecond
- Q:Detailed description of LED bulb lamp
- Using high quality, high-power LED as a light source, energy saving, environmental protection, and high brightness, long life
- Q:How to identify Ic constant current LED bulb?
- Let me tell you what. If the bulb is not damaged, the regulator needs a regulator to lower its voltage and see if the bulb's brightness is dark. If it follows, it is not a constant current source, but a blocking capacitor. If the voltage is greatly reduced, the brightness change is not constant, that is, the constant current source bulb (because the constant current source lamp can change between 80V--260V, the voltage is normal, and the output is constant).
- 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
