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's the flash of the bulb?
I don't know how you flashed this light. Did you flash or turn off the light before you left it?. If the lights are off, you should ask the electrician if the line on the switch is connected or not. If the switch is connected to the negative line, it will flash. If it is open after the flash, mostly driving power 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: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:Seeking the production process of LED bulb... Thanks
First of all, of course, the preparation of materials, the specific operation of the lamp to practice, each lamp has different methods of assembly, there are different work instructions. Only through practice can we write good and practical processes. Figure is a flow chart of MR16 assembly.
Q:Can the bulb's true life reach 30000~50000 by LED?
LED life and quality, work current and many other factors. Life is calculated according to the half of the light
Q:LED bulb w can replace 40W incandescent lamp
D lamp lumen value is ordinary incandescent lamp about 3 times, but LED ball bubble mask transmittance should be based on material, can use 10W or so LED acrylic mask ball bubble instead. Because I received a similar customer complaint, 7W's LED light bulb was replaced with an 20W energy-saving lamp, which was not bright enough.
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 material is applied to the glass cover of the LED bulb? Can reach 90% of the light, can not see the inside of the lamp. Who knows, thanks for telling!
Sandblasting can be transparent, light is not dazzling,But will still see the light...
Q:What are the characteristics of LED bulb?
Less power consumption, a 5 Watt LED bulb, equivalent to 40 watts of ordinary incandescent.
