American Bright introduces compact 10-watt and 20-watt light engines
American Bright’s new compact SSL modules offer higher power ratings and luminous flux in the smallest footprint possible, further expanding design freedom for designers of SSL luminaries.
Chino, Ca. September 8, 2008 – American Bright Optoelectronics Corp. announced today the introduction of two new compact light engine modules featuring its new direct die attachment (DDA) technology and integrated thermal management architecture that increases service life, luminous output and overall luminary efficiency.
The two new light engines are available with a power rating of 10 watts or 20 watts. The 10-watt light engine has a nominal diameter under 1.0 inch [24.6mm] and the 20-watt light engine measures only 1.3 inches [33mm] across its widest section.
Both light engines are ideally suited for luminaries designed to meet the growing demand for energy efficient, long life general illumination products that exceed the light quality and consistency of competing high power LED technologies such as standard hard and soft encapsulated LEDs.
The DDA technology allows for the placement of the LED die directly into cavities that are contained within the thermal interface. The die are glued down within the cavities, wire bonded, phosphor-treated and then encapsulated, all within the module, eliminating secondary soldering of the LED to a metal core printed circuit board (MCPCB).
DDA is significantly more efficient from a manufacturing standpoint, both for American Bright and for the end user, and reduces materials required to manufacture a high power LED system, thereby significantly shortening the manufacturing cycle time. Completely integrated modules can be secured to additional thermal interfaces, normally comprised of the final fixture, and connected to the driver system for final assembly.
DDA technology has many additional benefits over standard high power packaged LEDs that are commonly used to create solid-state lighting solutions. Packaged LEDs suffer from significant light loss due to internal reflection that DDA modules do not have. Packaged LEDs also are not as thermally efficient since they do not have a direct interface with the heat-spreading materials, this thermal inefficiency equates to larger external heatsinks and a greater expenditure of design and manufacturing time dedicated to thermal management. Packaged LEDs also display very distinct point source characteristics that require diffusion and advanced optics to overcome, both of which decrease efficiency while adding cost. The DDA modules provide a more uniform light source that creates a “solid block of light” rather than a matrix of hot spots. This uniformity significantly reduces glare, multi-angled shadowing, and the most common SSL-related complaint, the “un-naturalness” of the emitted light.
The 10-watt light engine will typically produce 550 lumens, creating a luminous efficacy of 55 lumens per watt (lm/W) in the warm white (3000K CCT) color bins. The 20-watt light engine will produce an impressive 1100 lumens in the same warm white color bin at the same 960mA. The light engines also come in a cool white (5000K CCT) that has an efficacy of 65 lumens per watt (lm/W).The total viewing angle of the emitted light is a wide 120 degrees, which creates an even dispersal of the total emission allowing for the use of lower cost reflector technologies to direct the light to the area to be illuminated. The light engine boast a maximum operating temperature ranging from -20°C to +60°C providing a wide margin for most commercial, industrial and residential lighting applications.
“The continuing development and expansion of our DDA light engine modules demonstrates American Bright’s commitment to the emerging Solid State Lighting Industry,” commented George Lee, President of American Bright Optoelectronics Corp. “We are providing a significant improvement over the current state of the art at a very market sensitive price point,” he added.
