LED chip on board improves efficacy by up to 10%, says Bridgelux
The eighth generation of LED chip on board (COB) devices from Bridgelux are claimed to increase energy efficiency and reduce the cost of lighting. They deliver up to 185lm/W across the company’s V series, Vero and Vero SE series product families at nominal drive current at the 3000K 80 CRI colour point. Efficacies above 200lm/W are possible at other colour points, says Bridgelux.
The COBs are claimed to optimise nominal light output to align with traditional lamp standards and are capable of up to three time overdrive, delivering a 30 per cent increase in maximum lumens per light emitting surface (LES). The increase lumens per dollar ratio reduced the cost of solid-state lighting, says Bridgelux.
There is a range of COB size and performance options from LES 8.0 to 29mm. They are also optically and mechanically consistent with earlier generations and technologically equivalent with current the company’s seventh generation COB LM-80 data. Iimproved alignment with industry standard drive currents enables the use of economical LED drivers to reduce costs, Bridgelux notes.
They are also covered by what Bridgelux claims is the industry best standard warranty of up to 10 years.
Bridgelux is also developing products for human-centric lighting applications. The Vesta Thrive COB is believed to be the industry’s first tunable white natural spectrum light source. It is also planning expansions in the Vesta Flex dual channel driver and controls family to include Casambi and Silvair control modules. Another development is the Vesta SE, the first dim-to-warm and tunable white COB with integrated holders to simplify and standardise mechanical, optical, and electrical connections.
Bridgelux Gen 8 products are now available for sampling and ordering with production shipments commencing in April 2020.
Bridgelux develops and manufactures lighting technologies and products for human-centric influenced light for the commercial, industrial and outdoor markets.
