Aeon Lighting Technology's LED Spotlight Receives UL Certification in the U.S. 2015-03-06
LED lighting manufacturer Aeon Lighting Technology (ALT) has successfully developed its first MR16 LED spotlight designed for use in fully enclosed fixtures, achieving UL certification for enclosed lighting applications in the United States.
When an LED light is placed in an enclosed fixture, the lack of airflow can cause the temperature inside the fixture to rise, negatively affecting the LED's heat dissipation and lifespan. As a result, most LED products are not recommended for use in enclosed fixtures.
ALT stated that its ALTLED MR16 (GX5.3 base) not only works in fully enclosed fixtures but also passed UL certification. During testing in a fully sealed environment, the temperature of the solid-state capacitors and power components remained within the normal operating range, ensuring a lifespan of 30,000 hours.
Due to heat dissipation issues, the market for enclosed fixtures has typically relied on traditional 50W halogen lamps, which are energy-intensive and have a short lifespan. ALT's ALTLED MR16 spotlight is expected to improve the light quality of architectural and landscape lighting while helping save energy. It is suitable for a wide range of applications, including outdoor landscape lighting, work lights, ground lights, and emergency backup lighting in enclosed fixtures.
ALT's General Manager, Mr. Luo Xianjie, explained that the heat dissipation structure of the ALTLED MR16 was carefully calculated. The 48 pure aluminum fins extending from the lamp cup beneath the chip are perfectly spaced to allow for optimal airflow while achieving the largest possible heat dissipation area. This design enables the spotlight to reach thermal equilibrium within 30 minutes.
In practical tests, the temperature difference between the aluminum substrate and fins of ALT's product was within 2°C, while competitors’ products showed a temperature difference of up to 18°C. A smaller temperature difference indicates that heat is effectively transferred, showcasing the superior heat dissipation performance of ALT's product.
