New LED solution for outdoor lighting

The 5050 LED is replacing the 3535 LED, which has long been the leader in the outdoor lighting market. The existing ceramic-based 3535 has excellent reliability but is expensive.

At present, the 5050 LED, which has achieved remarkable performance improvements in recent years, is targeting the market with price advantages. However, the 5050 LED must continue to enhance its reliability to become the mainstream of the market.

The American National Standards Institute (ANSI), an organization that oversees standards and conformity assessment activities in the U.S., publishes a comprehensive list of factors for consideration when designing outdoor lighting. These guidelines are updated to secure road safety and are expected to become more important due to climate changes. Therefore, the outdoor lighting industry has been looking for a more reliable and affordable lighting solution that can protect our safety and properties.
 
Samsung says its High Power LH502D is the answer to all these problems and is the ideal outdoor light source for overcoming the limitations of current outdoor lighting products.
 
This new solution increases the product life from 5 years to 16 years (based on 8 hours of operation per day) according to provided data.
Samsung’s exceptional ceramic coating technology prevents sulfuric gas from contacting the Ag (Silver) inside a package to prevent sulfide formation.

The ceramic coating also provides stronger resistance to the high humidity and salt fog to prevent corrosion and failure of the lighting. In addition, Samsung has applied Zener Diode to avoid Electrostatic Discharge (ESD), which is another critical failure factor for high-power LEDs, realizing stable performance in harsh environments.
