For reached the requirement of street light that output 85 lm/W. If led light engine can’t reach 110 lm/W then the street light can’t pass 85 lm/W spec.. Because the lens, power and heat effect will be decrease the led performance about 20%. Cool white is not easy to thread light through the fog and warm white can’t not reach street light requirement. It will endanger the stranger. So , Led street light toward 4500K for keep the performance and safe for stranger. Therefore, led package house exert to reach the 110 lm/W@4500K target. Lighten Corp., leading high power LED COB emitter maker in Taiwan, focus on LED COB related substrate & packaging business. Recently make the official announcement on succeed Lightan generation Ⅲ product launch . “ To compare with Lightan Ⅱ serious ( CCT :4500K, CRI70, eff. ~90 lm/W, by 25C, 300mA), new product -- Lightan Ⅲ are performed with the 20% higher on light efficiency and achieve 115 LM/W performance results”. Said by Lighten Corp. CTO, Rod Lin. And the most important is all the products are followed with ANSI compliance, this is not similar as the other players only care on the efficiency results but missing on the end user’s basic desire lighting needs. Because the higher efficiency results, end user offer the higher Lm/$ value to improve their competency. Meanwhile Lightan Ⅲ still keep the original dimensional design , and compatible with most industry fixture hard tools, lens , and power supply. Customers don’t need to spend more cost on to renew the new design. Lightan Ⅲ briefing : 1. Higher lighting efficiency 115Lm/W (4500K, CRI 70, 300 mA; 25 0C) ; 100Lm/W via over drive 20% case. 2. Die/Chip direct bonding on copper, the simply route on system thermal path structure. 3. Higher system thermal conductivity, 401W/m.K；Lower system thermal resistance (~0.52 C/W), certificated by IST. Outstanding on lower lighting decay. 4. ROHS compliant. ( certificated by IST) 5. ANSI compliant. 6. No Ag platted reflection coating, low discolor issue on long term lighting time, lower decay. 7. Multi view angle products selection: 120 Deg. or 140 Deg. 8. Multi CCT & CRI selections , 3000K ; 4500K ; 5700K / 80 ; 75; 70 9. Customized products acceptable, special design acceptable. 10. Friendly for fixture assembly. Following with Lightan Ⅰ/Ⅱ/Ⅲ product design concepts, we insist the “simply design is good” idea, for emitters are unitary size designs, and highest C/P value, by the shortest production lead time. Lighten overall production offering: From 3W ~320 W COB emitters, either DAM or DOT types. All samples & products are OK for requesting & selling.
