lighting emitters are growing

The technology has been used on emitters for backlight modules, automobile lamps, architectural indoor and outdoor lights, signage boards, and commercial lights. The company’s EHP-L02N emitters boast junction-to-sink temperature of only three degrees centigrade per watt. The emitters come in warm-white and white types, with the former giving off luminous flux of 500lm and the led high bay light. The emitters have been built into 20W and 25W streetlights. The 20W light generates 1,100 lumens at 1.8 ampere and the 25W light gives off 1,300 lumens at 2.2A.

With some unique packaging technology, the company’s EHP AX08 family of single-chip 10W emitters boasts efficiency of over 80lm per watt at 350mA. Thermal resistance is blow 15 degrees centigrade per watt. In addition to ceramic, the company also uses aluminum as packaging substrate. Both are good thermal-conductivity materials. To illustrate the power of its emitters, Everlight is demonstrating its Dolphin SL family of LED streetlights, which are equipped with its emitters. The 120W streetlights give off around 90-100 lumens per watt at 100-240 voltage and boast a power factor higher than 99%. "We guarantee a 20,000-hour life span for the light. The streetlight has passed the IP65 test for waterproof and dust-proof quality.

Eric Lu says that orders for the company’s lighting emitters are growing, helped by competitive pricing. He concedes that the lights using his company’s emitters are still pricier than traditional lamps, but notes that LEDs are more durable. If more people buy LED lamps, prices will fall more quickly, he says.Its 0.5W emitter is used in the led high bay light bars of refrigerators, and its 1W, 3W and 5W emitters have gone into streetlights, residential lights, signage boards and commercial lights. Its high-power emitters deliver efficiency of over 90lm per watt.
