How to choose a good led lamps
- May 26, 2017 -

The current LED lighting market, the price of the business reported a far cry, and say how good their own products, as an outsider to choose how to use when the quality of LED lamps to determine whether the 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 thermal structure; foreign original package of 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 efficiency, 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. At present, LED light efficiency and compact fluorescent light efficiency and almost the same, with the LED light efficiency, CREE this year, the amount of output can be 186lm / w 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.

3.The light source is a 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 .Drive power, good drive power can guarantee the life of the overall 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. High-power DC-DC DC converter, DC booster, 36V / 48V / 60V electric car inverter, electric car intelligent DC converter.

LED lighting options:

First of all should be clear their own positioning, you need high-end or mid-range lamps. From several aspects to consider the quality of LED lamps:

1. Chip type, now the domestic use of the most high-end is the United States CREE 3 chip, to 15 yuan / W. Followed by Puri and so on, as well as Japan, South Korea. Taiwan some of the chips. Personal recommendation is Puri chip, the price is higher,

2. Light failure with the lamp cooling and chip packaging is closely related to the packaging manufacturers should also be considered

3. Lumen value, now known to be able to do 130LM / W, personally think that indoor lighting 80-90LM the most appropriate, the most mature technology

4. Color temperature and lamp body surface treatment

5. Drive this should be said to affect the life of LED lamps a short board, most of the LED driver can only guarantee 2 years. That is to say you 2 years after the driver can be broken because of the lighting is not bright
