Q:Who knows where the broken LED bulb is?
The most common problem is that 1, the drive power is broken 2, the light source due to excessive or excessive flow leading to necrosis
Q:Secret LED bulb bubble price difference why so big?
Lamp beads。 I also do with Samsung bulb, bulb, lamp light cost more than others product price;
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:Is it possible to manually weld LED bulb bulbs?
As long as the welding technology clearance is possible or OK
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?
Of course, the hotter the better, because for the same material, the hotter it is, the more heat the LED chips use, the less good the quality of the chips. The thermal characteristics of lamps is mainly to measure the junction temperature of LED Shenglai rather than the temperature of heat sink. Aluminum is commonly used in heat dissipation materials.
Q:LED what is the glue between the aluminum base of the bulb and the cooling aluminum?
Heat conductive adhesive is best.Heat conductive adhesive, also known as thermal conductive silica gel. Organic silica gel as the main body, adding fillers, thermal conductive materials and other polymer materials, mixed by silica gel, has better thermal conductivity, electrical insulation performance, widely used in electronic components. Also known as: thermal silica, silicone rubber, silicone heat, thermal conductivity of silicone. The accelerator is used to solidify a transformer, transistor, and other heating elements onto a printed circuit board assembly or radiator
Q:LED how to classify bulb bulbs?See some LED bubble bulb specifications are written in A60, A45, and some are written G60, G45, I do not know, in addition to the maximum diameter of the same, what is the difference between the meaning of A and G?In addition, how can the whole LED bulb be classified, only by the maximum diameter, or with other classifications?,
LED bulb has two kinds of high power and small power, as well as color. High power bulb has a radiating fin from its shape. It is well recognized
Q:What does "A19" mean in LED A19 bulb?
I'm studying too! There's a problem for everyone to discuss
Q:What are the driving IC used in LED bulb?
Here are some of the models you want to know. You can contact me by mail and provide your detailed information and samples:Isolation without PFFT833S11 2.5W FT833A11 3-5WFT833B12 7-9W FT825 series 7-60WIsolation belt PFFT8900, 30W, FT8901 series adjustable light 30WFT8901B 7W, FT8901/2DD, DIP, built-in MOS, 24W adjustable lightNon isolation without PF:FT886A 7-24W FT883A 3-5W
Q:What's the reason why LED bulb gets a lot of heat?
LED light is a large amount of heat, more than 70% are calories. Different manufacturers are not very different
