68.3-556W 7785lm Nichia LED E21 4x4 Module 12x12cm 4000K
The latest innovation in LED chip design from Nichia, the direct mountable chip technology, good thermal design with minimum cost is now possible.
The Nichia direct mountable chips have the lowest thermal resistance on the market, only 0.3 (?/W junction to Ts measuring point), best chip size vs lumens ratio and consistent performance at high temperature. Therefore quality can be maintained while reducing the heat sink and case or it can be increased without modifying these two elements.
Featuring the direct mountable chip technology, the E17A and E21A LED series from Nichia can reduce cost and increase performance of street light and high bay light fixtures.
Aventrix, our new LED modules, use E21A Direct Mountable Chip LEDs and will bring high performance, efficient and reliable street or high-bay lighting within easy reach.
With E21A LED modules requiring minimum cooling, the total cost of the LED fixture is reduced, especially for the cooling element, usually made from aluminum, and the size of the enclosing. The cost of ownership is also very low due to the high luminous efficiency of 140 lm/watt and the well known excellent durability of the Nichia LEDs. A L70 lifetime of at least 43.800 hours, or 5 years of continuous operation is guaranteed.
System cost is further reduced with a hassle free installation via plug & play connectors and the PCB form factor with screw holes for fixation in place.
The PCB form factor brings freedom to use the E21A LED modules for a wide range of applications. It is immediately compatible with many 50x50 mm square optics from Ledil and Carclo. A few example of illumination patters:
To accommodate a wide selection of case design the E21 LED module comes in three LED configurations: 2x2 with 1945lm, 4x4 and 2x8, both with 7785lm.
For many street light projects usually one 7785lm module of 4x4 or 2x8 is usually sufficient and the power source can consist of a single 1400mA, 48.8V constant current driver, a very common type.
With operation up to 85 ? ambient temperature the performance specifications at 4000K color temperature are:
Other color temperatures are available on request.
