The LED Alternative to High Pressure Sodium Lamps

October 5, 2015

The Bridgelux OLM™ Series is a highly innovative integrated subsystem that delivers world class performance and meaningful cost advantages while reducing time to market, eliminating significant research and development costs, and improving manufacturing lead times. OLM Series is designed to replace the prolific high pressure sodium (HPS) lamp, which has become the standard lighting source in outdoor lighting applications.

Leveraging Industry Standards

Sodium lamps came to market in 1932 with the invention of the low pressure sdolium lamp (LPS.) After a few decades, the HPS lamp was introduced in 1964, and has since dominated the outdoor lighting market.  The mass adoption of HPS technology has standardized many applications such as roadway, parking lot, tunnel and canopy lighting around the fixed wattages, lumen outputs and patterns available.  Lighting OEMs have historically been challenged in converting these applications to LED light sources for a number of reasons including the lack of alternative LED-based products with an equivalent optical pattern, lumen level versatility, and design flexibility.

The Bridgelux OLM Series subsystem provides targeted lumen output levels combined with optics that achieve the precise lighting patterns commonly required in various outdoor applications. The OLM Series offering integrates Bridgelux LED light sources, optical lenses, and an electrical connection into a single environmentally protected product. This subassembly can be used as a base platform for a portfolio of products enabling the manufacturer to leverage luminaire castings, reduce design costs, and limit investment exposure.
