- Q:Is there any flicker in the LED bulb?
- First of all, I want to know what kind of LED bulb you bought. Is the LED light source small power or high power?Now on the market LED products, copycat too much, but also a lot of difference between quality and price, because the power output strobe filtering problem. Because the lowest requirements so the power design is very simple, such as shell is small power ball type PVC foam, with isolated power so far I saw several, but the price is very high, and most with the rectifier bridge, several rectifier diode, a capacitor, resistor several complete, low prices. High power type bulb is similar, but the power will be much better, is the constant current source in the output current of the filter is also doing well, there the strobe is low! Finally, the stroboscopic problem is on the power supply, and the power point difference is higher than one or two!!
- 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 LED price of aluminum alloy 3W is probably about 30.
- Q:What's the cause of the noise during the aging of LED bulb bulbs?
- The sound may be come from the power supply module components aging or faulty soldering and desoldering. LED long life, but may also be some problems.
- Q:LED what is the plastic shell of the bulb? What plastic material is better? What do you need to pay attention to?
- LED is the most important heat, light will not be so serious, the thermal conductivity is relatively high Aluminum Alloy, so LED manufacturers usually choose to use aluminum shell
- 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:Led the bulb is flashing. What's wrong with it? How do you fix it?
- There may be no aging, or there may be a power problem.
- Q:LED how does the bulb return electricity?
- What is reflow? Never heard of it. I am a lighting technician
- Q:Detailed description of LED bulb lamp
- Healthy LED is a green light source. The LED lamp is driven by DC without flicker. Without infrared and ultraviolet components, without radiation pollution, it has high color rendering and has a strong luminous directionality, good dimming performance and no visual error when the color temperature changes
- 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 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.
