Osram Unveils LED Module for Street Lighting

With Streetlight Advanced, OSRAM provides an efficient and future-proof solution for technical and decorative street lighting with LED. This durable module enables lighting without distracting stray light plus easy maintenance thanks to a lamp socket that is installed once only.

In addition to that the module is sustainable due to its standardised, consistent system interfaces as well as unchanging dimensions.

Compared with the mercury-arc lamps still widely used in street lighting, the Streetlight Advanced LED module saves a third of the energy. With a light yield of up to 60 lm/W Streetlight Advanced enables sustainable lighting.
 
The module itself comprises an LED, lens and reflector. An additional lamp socket is installed once only in the luminaire housing. Should even more efficient LEDs become available in future, the new modules can simply be snapped onto the existing socket without tools. The luminaire does not have to be replaced or modified, as the dimensions of any Streetlight Advanced LED modules developed by OSRAM will remain unchanged.
 
The streetlamps’ brightness can be individually adjusted, depending on the number of LED modules used. Plus, the modules can be perfectly controlled and dimmed using the appropriate Optotronic power supply and control gear.
 
With the modules’ high colour rendering index of 75-80, illuminated objects appear very natural without any colour distortion. Streetlight Advanced is available either at a colour temperature of 6,000 or warm white at 3,000K.
  
The module’s extremely long life of up to 50,000 hours in a luminaire with a suitable heat sink reduces maintenance costs. As modules can be replaced without tools, the Streetlight Advanced module offers key benefits with simple and fast maintenance.
 
Apart from their efficacy and long life time, the fundamental benefits of LED in street lighting are their directed light, i.e. the LED only emit light in the desired direction or on the desired surface. The Streetlight Advanced module’s particular optical concept – comprising LED, lens and reflector – enables a very high optical efficacy plus a street lighting according to the DIN EN 13 201 standard with very uniform and sharply defined illumination.
 
As such, despite its lower power input, an LED street lamp achieves brighter and more uniform illumination of a defined surface. This enables the road to be illuminated ideally and in conformity with standards without scattered light and adherence to glare limitations.
 
Streetlight Protect:
As a further addition to its LED outdoor lighting portfolio, OSRAM’s Streetlight Protect is a modular, scalable solution with 15 high power LEDs. These allow several 1,000 lumen units to be combined and are therefore suitable for any application. The IP66 rating sets the standard for outdoor use in its moisture and dirt resistance. The integrated heat sink provides the cooling required. The module’s symmetric light distribution enables standard-compliant lighting at the side as well as the middle of the street. With 20 percent less energy consumption compared with conventional sodium vapour and halide lamps and easily replaceable units, Streetlight Protect saves on energy costs and time due to less maintenance work.
