The new product uses a through-hole heat-dissipating package and has been RoHS-certified (indicating that it does not contain harmful substances such as mercury). The life expectancy is increased by more than 10 times, the cost is reduced by more than 50%, and the energy consumption is reduced by more than 70%. It also has superior light performance.
New products are used in a wide range of applications including: safety (anti-counterfeiting for currency, passports and other documents), forensic identification (for analysis of various body fluids during forensic identification) and photocatalyst (air and air for use in homes, offices and cars) Water purifier).
According to Lumex, the new UV LEDs are packaged in a TO-46 package that replaces the original epoxy lens with a glass lens, making the life of the new QuasarBrite UV LED products more than 10 times longer than the original, exceeding 50,000 hours.
In addition to greatly extending the lifespan, the QuasarBrite series of UV LEDs provide a more uniform beam direction. Compared to cold cathode fluorescent lamps (CCFLs), there is no need for a secondary light distribution with a lens, and the mercury-free and more durable, the maintenance cost of the UV LED is greatly reduced, and the energy consumption is reduced by 70%. Won the advantages of low cost and high cost performance.
In addition, QuasarBrite UV LEDs feature an 80-degree viewing angle and operate over the -40°C to 100°C temperature range. Available from stock. Pricing is based on the order quantity, and the price per chip is about $20 to $28. The production quantity of each chip is mainly determined by the chip size and the order quantity.
