How to determine whether the quality of LED mining lamps
The current LED lighting market, the business reported that the wall washer, spot lights, point light source price difference is very far, and say how good their own products, as an outsider to choose how to use when to determine the LED lighting Is quality up to standard? LED lighting quality to see a few parameters:
1. Light failure, better LED lamps in 25000 hours before the light failure <30%; determine the main factors of light failure is the light source is good or bad, the difference between the cooling structure; foreign original packaging high-power light source, such as CREE light source Light failure is better than the domestic package of light source, as the layman generally do not see the light source, a simple way to judge the main price, the original foreign packaging light source than the domestic package of light source price much higher; so to buy better quality LED The lamp must provide the manufacturer information of the light source. High-power DC-DC converter, DC booster, 36V / 48V / 60V electric car inverter, electric car intelligent DC converter .24V-72v electric vehicle controller, etc.
2. Light effect, that is, the number of dollars per watt, the unit LM / W, he is to reflect the energy-saving lamps, energy-saving lamps, the higher the luminous efficiency. LED light efficiency and compact fluorescent light efficiency and almost the same, with the LED light efficiency, CREE this year may be the output of 186lm / w light source. Spot high-power DC-DC converter, DC boost Device, 36V / 48V / 60V electric car inverter, electric car intelligent DC converter .24V-72v electric car controller.
3. Light source, high power LED or straw hat or piranha type LED; LED lighting with high power LED as a light source, the price is higher; and straw hat or piranha type LED price is very cheap, not suitable for lighting Level light source. High-power DC-DC converter, DC booster, 36V / 48V / 60V electric car inverter, electric car intelligent DC converter .24V-72v electric vehicle controller, etc.
4. Driving power, good drive power can guarantee the life of the whole lamp, LED theoretical life is 100,000 hours and the general drive power life of less than 100,000 hours; in order to ensure the overall life of the lamp, driving power is also a key link; On the one hand the LED must be constant current drive, if the use of low-cost constant voltage drive will shorten the LED life. As an ordinary consumer how to identify the LED drive power is good or bad? See a few parameters, light failure, life, light efficiency, and warranty life. Dare to provide long-term warranty of the manufacturers of LED lamps produced better quality.
