Q:What's the reason for the LED bulb strobe?
8W offline LED driver GreenPoint reference design with solid state lighting standard energy star "as an example, the sine wave regulator side flyback power conversion does not provide constant energy to the primary bias, dynamic self supply (DSS) circuit can be activated and the light induced flicker. To avoid this problem, it is necessary to allow primary bias to be discharged at each half cycle, and accordingly, the values of the capacitance and resistance that constitute the bias circuit need to be appropriately chosen.
Q:LED bulb is broken. The luminous patch is not bad. Can it be made into USB lamp?
When electrons and holes are combined, they can radiate visible light, so they can be used to make light-emitting diodes. In circuits and instruments, as an indicator, or in combination with text or digital display. GaAs diodes glow diode gap, green silicon carbide, yellow light diode, light emitting diode gan. Because of the chemical properties and organic light-emitting diode OLED and inorganic light-emitting diode LED.
Q:How to choose the bulb power?
If it is household, choose the separation side, because the separation type is relatively safe, easier to pass through safety regulations, but the cost is relatively high, but suitable for home use.
Q:In a bulb, the ambient temperature of the LED is LED, the temperature of the air in the bulb, or the temperature of the aluminum substrate
LED working environment temperature refers to the temperature of the air in the LED bulb, not the temperature of the aluminum substrate. The temperature of the aluminum substrate will rise as the LED lights up, and rise to a certain extent, which will involve the highest environmental temperature.
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:Can the bulb's true life reach 30000~50000 by LED?
The theory of the life of LED is one hundred thousand hours, this is not true; but the LED life is far less than one hundred thousand hours, only ten thousand hours, which is currently the most industrialized production of long life; because the quality of the LED part of the core - epitaxial wafer has not reached the ideal state, there are many problems to be solved, such as reducing the dislocation the density of epitaxial film, high quality P GaN preparation etc.
Q:What are the types of LED bulb?
According to the power points, LED bulb has 1W, 3W, 5W, 7W, 9W, 12W, 15W and other power, customers can choose according to brightness requirements.
Q:LED bulb after the power failure, still glimmer, can last hours or even all day, what is the reason?!
If the switch is installed on the zero line, LED is the resistance capacitance step-down if the light shimmer is mainly the induction voltage capacitance inside (with the switch installed on the line Never mind, because there are capacitance induction voltage). The meter won't turn. Of course, you can not expect to use this induced voltage to lighting, because this voltage is extremely weak, unable to meet the minimum requirements for lighting. If the switch is on the zero line, and there is a problem with the capacitor in the capacitive circuit, it is likely to be a long time. Over time, the circuit in the LED light proved to be a problem
Q:Are there any differences between negative ion bulb and LED bulb?
Negative ions should belong to traditional lighting technology, LED is the latest lighting technology
Q:I want to ask for high power LED bulb lamp wire inexplicably broke, and in large quantities. Is the quality of the lamp?
Have you used it or haven't you bought it yet?
