Welome to send inquiry,we will reply soon.If you want to know more,pls feel free to contact us.
- Q: The office, sample room, corridor, the most commonly used several LED downlight which is several dimensions, what is power?
- The office uses 4 inch and 6 inch downlight, lighting power within 12-20w, ensure the light illumination to 100-200LUX office.The brightness of the corridor can be slightly darker, with 3-4 inch LED lamp, lamp power in the 6-12W, the more suitable for light illumination to 50-100LUX.
- Q: How much is the general 15WLED lamp luminous flux.
- Of course, can also use 30142835 beads to do warm (below 4000K temperature) will be low, cool (above 6000K temperature) will be higher
- Q: What brand of downlight is good? Please explain the reason, thank you!
- Quality. After deciding to buy LED lights, you'll have to see what quality LED lights you need. At present, the country has not yet introduced LED lighting quality standards, so the market LED product quality is uneven, some very cheap brand-name goods using the chip quality is very poor, that is 1W, only 0.5W-0.7W, and manufacturers in order to do high brightness, it will increase the output current of power supply, it will cause serious decay. Should choose some brands of their own products, such as "one enterprise", "Hangzhou ray", "silver rain" and other brands.
- Q: How are LED lamp quality is good or bad?
- Drive power. A good driving power can guarantee a whole lamp life, theory of life LED lamp is 100 thousand hours, and the driving power of general life ranging from less than 50 thousand hours. So in order to ensure the whole lamp life, LED lamp manufacturers tell you that the driving power is very important, and it is also one of the most critical components. On the other hand LED downlight must be a constant current power supply, if using constant voltage power supply low cost will greatly shorten the service life of LED lamp. Then, how can we identify the constant current power supply? You can see several parameters, service life, light, light effect and warranty period. If the service life is longer, the quality of the power supply will be relatively better.
- Q: Turn off the lights after the bright LED lamp
- The choice of switching error, with indicator light (excluding fluorescent) switch is not suitable to control like small power LED energy saving lamp load, because the load current through the indicator light through to the small power is not already small. A resistor of several hundred K in parallel with the ends of the load can be improved, or the indicator light can be changed directly, and the indicating lamp for canceling the switch can also be improved.
- Q: Why use LED lamp light source patch
- In a large number of automated production, the packaging cost of the patch LED itself and the cost of soldering to the circuit board are lower than those of the small power LED.

The so-called "anti fog lamp" on the Internet is nothing more than the high sealing degree of the panel and the soft light emitted by the semi transparent panel.
