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's the reason for the LED bulb strobe?
Common causes and treatment of LED light flashing:Generally, the human eye can detect light flashes with frequencies up to 70 Hz, which are not sensed above this frequency. Therefore, in LED lighting applications, if the pulse frequency appears below 70 Hz low-frequency components, the human eye will feel flashing. Of course, in specific applications, there are a variety of factors that may cause LED lights to flicker. For example, in offline low power LED lighting applications, a common power topology is an isolated flyback topology.
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's the reason why LED bulb gets a lot of heat?
If the radiator is about the same size, it's not nice to touch the low temperature, because the heat accumulates in it and doesn't come out. The.LED lamp doesn't last long
Q:Secret LED bulb bubble price difference why so big?
Structure. LED heat dissipation is very important, good bulb will be equipped with radiators, inexpensive, and its life can be imagined
Q:LED thread specifications for bulb bulbs?
Ordinary home E27 screw lamp ah, there is a need to ball on Taobao, art night lights, E27, E26, B22, E27 specifications in the majority! E27, E14, G10, E40 are more commonly used Oh!
Q:Is there any flicker in the LED bulb?
That should be a combination of small power and multiple LED lights! The main reason is the strobe power problem, to tell the truth, I do not set the LED power supply, improvement in the well to be unable to give you much help, our production of LED products, the procurement of materials and parts suppliers will request strobe or in the power supply design problem, if you want to buy LED products, especially is the bulb, I suggest you buy a large power assembly (i.e., the shell is Aluminum Alloy)!
Q:How did the trademark on the LED bulb go up?
Laser printing and screen printing, pad printing can be, look at the needs and equipment.
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.
Q:How does the LED bulb look good or bad?
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.
