Methods to Select Led Spotlights

Brief Introduction of Led Spotlights

As LED technology continues to mature and costs continue to decrease, LED spotlights have been widely applied in a variety of places, while the development and popularization of led spot lighting still face many problems. How to develop a cost-effective LED spotlight, how to solve the heat dissipation problem of high-power, high flux LED spotlight, how to achieve modularity and interchangeability of LED spotlights, how to fully embody the LED’s characteristics of long-life, high luminous efficiency and controllability, and how to make people enjoy the colorful lighting and access to more affordable, more secure and reliable LED products are the key problems which requires the joint efforts of the manufacturers and industry professionals.

Security Certification of Led Spotlight

The safety requirements of the most LED spotlights refer to the traditional lighting LED spotlights and a set of safety certification standards has formed based on its own characteristics. Currently, in the aspect of e27 led spot light certification, the international community is mainly the European CE and UL certification in North America-based and voluntary certification (CQC) in China. CE certification contains LVD and EMC, LVD is executed in accordance with the EN60968 standard (will be upgraded IEC 62560) and EMC is carried out according to EN55015, EN61547, EN61000-3-2 and EN61000-3-3 standard. In addition, LED lights also refer to IEC 62471 to test in the light biosafety. In North America, it is usually required UL safety and FCC EMC certification. UL implementation standards are UL1993, UL8750 and UL1310; implementation standard of FCC is the FCC PART15 Subpart B. In China, LED spotlight is a voluntary certification (CQC) with the standard GB24906-2010 (safety) and GB 17743-2007 (electromagnetic compatibility). In addition, in the aspects of the performance of LED spotlights, there are many other standard requirements and these all make requirements on LED Spot color temperature, color rendering index, initial luminous flux, luminous efficiency, lumen maintenance life, the center beam intensity, nominal power, power factor, and product identification provisions.

The Working Life of LED Spotlights

Thanks to the life of LED spotlight takes the solid-state light emitting diodes as the light source, the light-emitting life mainly depends on the solid-state LED light source and the cooling part. So far, the life of LED light source has reached more than 100,000 hours, and with the growing development and popularization of application technology, the aspects of drive and cooling basically achieve the ideal state, a high-quality LED spotlights life basically reach 10000-50000 hours. LED lighting products save 80% electricity, and they are almost maintenance-free, there is no problem of frequent replacement parts. Green-semiconductor light source with soft light and pure spectrum is good for eyesight protection and good health.
