Intelligent lighting will be LED lights inevitable trend of future development
As the high cost of LED lights, energy saving is not the only way to convince the consumers, if we use intelligent lighting, with low cost, easy to use, flexible scene settings (automatic dimming, auto heating and light) and return on investment time is short and other advantages, then the consumers will tend strong willingness to pay. Obviously, intelligent lighting lit the spark of imagination semiconductor manufacturers, let gorgeous pace is accelerating.
ZigBee has a bright future
ZigBee Alliance released a new application specification ZigBee Light Link (ZigBee lighting connection), many manufacturers introduced new rules-based intelligent lighting solutions.
LED lighting control wireless, networking technology is an important trend, mobile phone, tablet PC and so can achieve color LED lights dimming, and only takes a chip and control terminals can be achieved. But the wireless intelligent lighting also has a different "solution", the current for different types of applications, there are many kinds of wireless protocol stack source code. For intranet or Internet access, the most commonly used WiFi. For real-time control, then there is currently very popular JenNet-IP and ZigBee. Gateway is responsible for TCP / IP and JenNet-IP or ZigBee protocol stack source code conversion between. Can be controlled from the overall economic cost considerations, the current ZigBee, JenNet-IP is the most suitable for these two modes LED wireless lighting controls. The former camp wider, TI, Freescale, Marvell and so in efforts to promote the latter by the NXP pushing.
Since ZigBee technology since the emergence of market performance has been praised, but with its own sound and find the "smart lighting," the fulcrum, ZigBee leveraging the market. Last year, the ZigBee Alliance released a new application specification ZigBee Light Link (ZigBee lighting connection), simplifying the design, the use of this specification ZigBee network applications control the lighting more easy to use. ENELTEC said that by the end of October last year, it released a Philips lighting connection using the ZigBee specification, the $ 199 can be modulated light intelligent lighting products, including three dimmable LED lights and the gateway, integrated ZigBee + Ethernet interfaces, the gateway with a network cable is connected, via phone or tablet application can be downloaded HUE adjust light levels, significantly increases operating ease.
TI occasion to force, and the development of system-on-chip (SoC) CC2538, CC2530, based on the previously made substantial improvements will not only ARM Cortex-M3, memory, and hardware accelerators highly integrated, but also supports ZigBee as well as other factors such as 802.15. 4 and 6LoWPAN IPv6 IP-based standards. TI recently organized Demo shows reporter saw, development board with CC2538 chip as the master, the board also includes a Light Link's WiFi chip, which is equivalent WiFi + ZigBee router. that unlike traditional WiFi chip, TI's WiFi chip to the main stack integrated on a single chip, the external API application interface can only control WiFi, connected to the phone via WiFi to the home gateway, CC2538 can control WiFi Modules issued an order LED lights for brightness adjustment, operation is quite simple. Currently existing customers based on the development board to do the design, development tools have been in the online public, the underlying protocol is open, just buy the TI chip can get burned into the standard chip stack doing development.
New smart bulb wireless platform will not only its low power AC / DC controller and wireless microcontroller embedded intelligent LED bulb, but also includes a simple, low-cost ZigBee remote control, a micro-controller based on Marvell WiFi WiFi module dedicated to ZigBee lighting bridge device for light bulbs directly with the gateway and wireless router.
ZigBee has a bright future. Based on the Feedback from the market, the new listing of 100,000 sets of ZigBee-based intelligent lighting system will soon be sold out, precisely because of its order to bring a new experience. ZigBee Smart lighting solutions for commercial and popularity in North America, will also be a breakthrough in the Chinese market, but also the traditional lighting manufacturers do not understand this concept, and therefore need to cultivate the market for some time.
