Bo tells cause LED Ceiling Installation Notes (1) When installing ceiling lights in masonry structure should be used embedded bolts or expansion bolts, nylon plugs or plastic plugs fixed; not use wedge. And the carrying capacity of the stationary member should match the ceiling light in weight phase. Ceiling fixed in order to ensure solid, reliable, and extend its life. (2) When using expansion bolts, should be the choice of technical requirements bolt specifications, the hole diameter and laying depth to match the bolt specifications. (3) Number of fixing the lamp holder fixing bolt should not be less than the number of holes on the lamp base and bolt diameter should be matched with the aperture; no fixed mounting holes on the base of the lamp (when installing self-drilling), for each lamp fixing bolts or screws not less than two, and the center of gravity or center of gravity and lamps to match the screw bolt; only when the insulating units in 75mm diameter and below, before using a bolt or screw. (4) Ceiling not directly mounted on flammable objects, some families for aesthetic lining behind the plywood ceiling lamps with paint after the fact, this is very dangerous Zhengzhou LED street dealer home insulation measures must be taken; if light surface temperature parts near the fuel, heat or cooling measures should be taken. (5) should also be checked before installation Ceiling: ① lead section of each fixture wire line core, Tongxin soft line is not less than 0.4 mm2 copper core of not less than 0.5 mm2, or lead must be replaced. ② wire and lamp connection between the lamp connected in parallel to a solid lead, should be good electrical contact, in order to avoid due to poor contact, sparking occurs between the wire and the terminal, and dangerous. Bo tells the good cause Tier 1 LED, do not use bipolar power devices Doug Bailey pointed out that due to the bipolar power devices cheaper than the MOSFET Zhengzhou LED lights, usually about 2 cents a Zhengzhou LED lights manufacturer Which is good , so some designers led drive to reduce costs and the use of bipolar power devices, it will seriously affect the reliability of the circuit, because as LED drive up circuit board temperature, effective operating range of the bipolar device will rapidly shrink. 2, do not use voltage of 600V MOSFET breakdown voltage of 600V MOSFET cheaper, many believe led lamp input voltage is generally 220V, 600V so the pressure is sufficient, but many times the circuit voltage to 340V, there is a surge in the time , 600V breakdown of the MOSFET can be easily, thus affecting the LED lamp life, in fact, the choice of 600V MOSFET may be some cost savings, but it is the price paid for the entire board, so "Do not use 600V breakdown voltage MOSFET, The best selection of voltage over 700V MOSFET. "he stressed. 3, try not to use electrolytic capacitors LED driver circuit in the end not to use electrolytic capacitors? There are supporters and opponents, supporters believe that if you can control the temperature of the circuit board, extend the life of electrolytic capacitors in order to reach a goal, such as the choice of 105 degree life of 8000 hours of high-temperature electrolysis capacitors Zhengzhou LED lights best manufacturers, The electrolytic capacitor life estimation formula accepted "the temperature is 10 degrees lower, life expectancy doubled," then it at 95 degrees ambient operating life of 16,000 hours, at 85 degrees ambient operating life of 32,000 hours at 75 ° environment working life of 64,000 hours, less if the actual temperature, then life will be longer!
