led high bay light choose high quality drive power
led high bay light choose high quality drive power
1. Why led high bay light need a high quality drive power ?
Since the LED does not contain toxic substances, environmental protection, long life, high efficiency photovoltaic many advantages , LED chip design and production and manufacturing processes have been quite mature , damaged the entire LED lighting system LED driver is mainly damage ; LED drive power due to the low quality of protection is not perfect, great damage will become low precision constant current LED chip current fluctuations ; therefore LED drive power LED lighting is the key , it is like a person's heart , to manufacture high -quality , LED lamps for lighting must use high -quality LED power driver to be able to meet the harsh working environment LED lighting systems and high maintenance cost requirements .
2. where the root of LED high bay light driver quality ?
A non-professional power supply design and manufacturing company ( requirements are too loose , too small ) ;
The second is not in accordance with the harsh working environment LED lighting design
a) -35 degrees to 70 degrees ambient temperature
b) waterproof design is not in place
c) mine design is not in place
3 How to ensure the LED high bay light driver quality and reliability ?
1 ) Professional design specification process control technology pre-research , feasibility assessment, preliminary design , detailed design , engineering, prototype and small batch trial production.
2 ) a reasonable margin component design
3 ) selection of high- quality components electrolytic capacitors , IC, power semiconductor , magnetic components.
4 ) strict quality verification and testing procedures
Stress analysis , EVT, SVT, DVT , such as testing and MTBF calculations and experimental verification.
4. Why do we need efficient led high bay light drive power ?
High efficiency LED lighting systems overall energy requirements, low temperature rise , long life, high reliability and guaranteed basis . 1 ) High efficiency, low loss , low temperature rise like a console output 100W LED drive power , when efficiency up to 95 %, the loss is 5.2W, when the efficiency is only 85% , the loss of 17.6W, the latter is 3.4 times , experiments show that under the same conditions the former than the latter low temperature 10 ~ 15 ℃.
2 ) reduce the operating temperature of the LED light failure LED chip and delaying temperature rises will lead to changes in the electro-optical conversion efficiency of light-emitting device performance decay , even when serious failure , experimental tests show : LED temperature increase of 5 degrees Celsius itself , flux dropped 3%.
3 ) High efficiency, low temperature rise , long life if the choice of 105 degrees , life expectancy of 10,000 hours of high-temperature electrolytic capacitors, electrolytic capacitor life according to the prevailing estimate of the company , " each 10 degrees , doubling the life ," then it is at 95 degrees ambient the working life of 20,000 hours at 85 degrees ambient operating life of 40,000 hours , as Ron platinum drive power in general operating temperature of up to 70 degrees, the temperature of the electrolytic capacitor is substantially controlled at about 85 degrees , then the life expectancy of up to 40,000 hours , such as by working 12 hours a day total , the life expectancy in recent decades.
4 ) High efficiency, low temperature rise , high reliability
With the reduced supply temperature , IC, improving power semiconductors work environment , MTBF ( mean time between failures ) will significantly improve .
5 What is the PF? What is the PFC? Why should high- PF?
Power Factor PF is the abbreviation refers to the power factor, active power and apparent power ratio ; PFC Power Factor Corrector is the acronym refers to the power factor correction ;...
