In the outdoor lighting sector, manufacturers mostly emphasized luminous efficacy and light shape, due to advancements in LED technology and luminous efficacy at Light+Building 2014 that took place from March 31 to April 4, 2014 at Frankfurt Fair and Exhibition Center in Germany.
Previously, LED streetlight manufacturers tended to emphasize heat dissipation and reliability. At this year’s show LED streetlight manufacturers focused on sustainable management concepts. Therefore, manufacturers were advocating the benefits of replaceable LED streetlight modules to reduce repair costs and extend LED streetlight lifetimes.
In addition, to prevent light from affecting homes or crops most LED streetlight manufacturers use reflectors to focus light beams onto the road. At the show, it can be observed that more LED manufacturers are using special optical lens shaped designs for this purpose.
Looking into design trends of large luminaire manufacturers, it can be noted renowned automotive luminaire manufacturer HELLA is emphasizing long term operation. In the automotive industry, automotive lighting manufacturers need to guarantee auto makers the same components will still be available after many years for purchase. HELLA also emphasized a similar concept with its streetlight products, by using standardized light source module designs. Once the streetlight passes the five year warranty, clients can still find the same luminous flux and color temperature LED luminaire modules. The only difference will be rising luminous efficacy will create products with lower power consumption.
