Aug 28, 2017: Smart solid-state lighting (SSL) systems have emerged as one of the popular applications used extensively across residential lamps, smart cities, etc. However, in residential and commercial lighting, there are certain possibilities that such smart technology can waste energy in the form of standby power.
SSL Annex report
The IEA (International Energy Agency) 4E SSL Annex has published a report on smart LED lamps that shows early results of its viewpoint into standby power. Smart LEDs need to be powered on at an extremely low level so as to respond to commands given via a wireless network.
The SSL Annex is an organization that is aimed at solving roadblocks to the adoption and best usage of LED lighting. It was created by nations with a chief stake in SSL adoption such as the US, Australia, the UK, France and others.
Environmental activists and government regulators opine that the wasted standby power can remove the energy efficient benefits of LEDs. The early report released by the SSL Annex talks about the findings of a study conducted on this standby power concern.
Standby power concerns
Smart LED lamps differ massively in standby power. The products that Annex studied varied from 0.15W to 2.7W. Furthermore, average numbers point out that the issue needs to be addressed to at the earliest. The average standby energy usage each day amounted to 51% of the quantity of energy that the average lamps used in an hour of powered-on utilization.
The efficacy with standby power varies from 9 to 51 lm/W. This means that certain products perform worse as compared to traditional incandescent lamps, according to the report. Standby energy use signifies that 35% of the total efficacy ranges from 16 to 64 lm/W.
Further, SSL Annex is also looking at other factors associated with smart LED lighting for residential applications. For instance, most smart LED products use wireless networks like Z-Wave, 6LoWPAN and ZigBee, which require a dedicated gateway that also requires power.
Now, if the industry unites on such standards, then support for the network can be integrated into home network products like Wi-Fi routers, which are used in various events .
When it comes to networking standards, the SSL Annex is also looking into some feasible options. Lack of interoperability can disrupt the smart lighting movement across homes, says the report.
