Q:Ordinary lamp LED bulb can?
As long as the inside of the interface is the same, for example, the E27 interface (ordinary spiral, that can be installed energy-saving lamps) installed there is no problem, LED bulb is now a lot of 110V-220V high voltage power supply, so the stability is very strong, the key is to save electricity, saving seventy percent than the energy-saving lamp, no effect, ease of use.
Q:What are the characteristics of LED bulb?
Energy saving research data show that, as LED is a cold light source, semiconductor lighting itself has no pollution to the environment, and compared with incandescent lamps and fluorescent lamps, the power saving efficiency can reach more than 90%. Under the same brightness, the power consumption is only 1/10 of ordinary incandescent lamp and 1/2 of fluorescent lamp tube. If we replace 50% of our traditional lighting with LED at present, the amount of electricity we save every year will be equivalent to the sum of the total power generated by the Three Gorges power station, and the energy saving benefits will be considerable. LED, the lightning man at home, is pretty good
Q:How to choose the bulb power?
If the public is not high, the quality requirements, and to control the price, you can choose non isolated, because it does not require isolation transformer, so the cost is relatively low, but the aluminum substrate voltage requirements is relatively high, otherwise there may be charged radiator, and still light outside is not very beautiful.
Q:Is it possible to manually weld LED bulb bulbs?
You can ignore the effect of heat conduction and thermal grease, solder is better, I was doing a lot of tests, the thermal conductivity of thermal grease is about 1.2 to 2, aluminum more than 300, thermal grease just to fill the bottom of the LED and the aluminum substrate contact surface gap, you don't fill gaps don't hinder it the normal contact with the aluminum substrate at the bottom of the LED, will be lost, and the use of thermal grease you for about a year will have to replace the thermal grease, only unscrupulous vendors will deceive others say I added thermal grease, heat conduction effect is not fully qualified, in fact, for a long time, the potential will LED light spot the chip inside the loose because of the long-term high temperature, causing the current growing, until completely off
Q:LED bulb PC, will the white cover affect the color temperature of the finished lamp?
Our company is doing LED lamps, about the color temperature has indeed been deviation, we call this phenomenon called drift. But there will be no 6000K drift, and there are two possibilities for you
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 work environment refers to the external work room temperature, LED lamps also have a working temperature, general LED lamp in the case of work, the external temperature is below 65 degrees is normal.
Q:Can the bulb's true life reach 30000~50000 by LED?
The white LED lighting bulb basically is to use GaN based blue LED excitation light yellow fluorescent powder to realize white light, which is a two yuan color white, there are three kinds of RGB LED chip mixed light, but the high cost of LED, the general industrial production less
Q:How does the LED bulb go with the power?
voltage range as long as the 36V can be achieved, for example: voltage range 24v-80v is very good,
Q:What are the types of LED bulb?
The LED bulb replacement use convenient, makes this type of products are widely accepted by users by the family, under the same illumination conditions choice to replace the traditional lighting.
Q:I want to ask for high power LED bulb lamp wire inexplicably broke, and in large quantities. Is the quality of the lamp?
The second continued the problem: welding line, this work continued not done!
