At present, the prices quoted by various businesses in the LED lighting market are far apart, and they all say how good their products are. As a layman, how to judge whether the quality of LED lighting meets the standard when choosing to use it? The quality of LED lamps mainly depends on several parameters:
1. Light decay
The light attenuation of better LED lamps is less than 30% before 25000 hours; the main factors that determine the light attenuation are the quality of the light source and the difference in heat dissipation structure; the high-power light source packaged by the foreign original factory, such as the CREE light source, has a better light attenuation than domestic The packaged light source, as a layman, generally cannot see the light source. The simple judgment method is mainly the price. The price of the light source packaged by the foreign original factory is much higher than that of the domestic packaged light source; therefore, if you want to buy a better quality LED lamp, you must provide a light source. Manufacturer information.
2. Light effect
That is, the number of lumens per watt, the unit LM/W, it reflects the power saving performance of the lamp, the better the power saving, the higher the light efficiency. At present, the luminous efficiency of LEDs is almost the same as that of compact fluorescent lamps. With the improvement of LED luminous efficiency
3. Light source
Is it a high-power LED or a straw hat lamp or a piranha-type LED; LED lighting fixtures use high-power LEDs as the light source, and the price is relatively high; while the price of a straw hat lamp or a piranha-type LED is very cheap and not suitable for lighting-level lamps. .
4. Drive power
A good driving power supply can guarantee the life of the overall lamp. The theoretical life of LED is 100,000 hours and the life of the general driving power supply is less than 100,000 hours; in order to ensure the life of the overall lamp, the driving power is also a key part. How do ordinary consumers recognize the quality of LED driving power? Look at several parameters, light decay, service life, light efficiency, and warranty period. The quality of LED lamps produced by manufacturers who dare to provide long-term warranty
Selection of LED lamps:
First of all, you should be clear about your positioning, whether you need high-end or mid-range lamps. Consider the quality of LED lamps from the following aspects:
1. Chip type
2. Light decay
3. Lumens
4. Color temperature and surface treatment of lamp body
5. Drive
6. Beam angle
