IMS Research forecasts that shipments of RF-embedded light bulbs and their associated remote controllers will be more than 6,00,000 in 2013, rising to 1.17 crore in 2017. 2013 will be a big year for the emergence of RF-embedded light bulbs, with several large manufacturers planning to release new products using a range of wireless technologies, said IMS.
There are several drivers to push the market for these devices forward. One of the most important is the ability to control the lights using a smart phone, which can provide both in-home control, and for some systems, remote-access control from outside. It is expected that over the forecast period, most of these systems will offer remote access via an app, or cloud-based service. While this feature is available on current residential lighting control systems, the cost of these systems can be too high for most consumers. The RF-embedded light bulbs will be sold at a more consumer-friendly price level, leading to higher residential adoption.
According to IMS Research Analyst Phillip Maddocks, "We have already seen excitement about these types of systems with the recent successful launch of the Insteon RF and Powerline LED bulb as well as Li-Fx system that managed to generate very significant investment in a few weeks; this shows the potential of this market. In addition to this, several tier-one lighting suppliers are planning to launch similar systems towards the end of 2012 and throughout 2013, which will bring such systems to the consumer market."
From a technology perspective, Embedded System currently most RF-embedded light bulb systems, such as that of Insteon, use a proprietary technology or use a proprietary 802.15.4 software stack. Greenwave Reality is currently showcasing NXP's JenNet-IP protocol which, according to NXP, is being made an open platform for other semiconductors to support. In addition to this, the ZigBee Alliance recently launched a lighting-specific profile "ZigBee Light Link" which is designed specifically for the control of both colour and light level of LED light bulbs. Currently several tier-1 lighting manufacturers, such as Osram and Philips, have already had devices certified using this protocol.
"Over the next few years, there will be the development of several ecosystems of devices using different technologies before a dominant standard emerges," added Maddocks. "With the support and the interoperability available as part of the ZigBee Light Link protocol, IMS Research believes that by 2017, ZigBee will have emerged as the main wireless technology being used in these systems, accounting for 38 per cent of all RF-embedded bulbs and controllers shipped between 2010 and 2017."
