Lighting is not only just about bringing us out of the dark. Light fittings, especially LEDs are becoming the accepted norm, which is a good thing. However, it means manufacturers and suppliers are upping their game in other areas. Light fittings now have increased capabilities including intelligent lighting, sensors and color tuning.
Wireless connectivity is also taking its place in shaping the future of lighting. Although the wireless technology for lighting has been around for some time, the cost is expensive to many. Yet, this is changing – as is our familiarity with wireless in other areas of life too. Digital lighting via a Bluetooth connection has huge potential. Imagine a light which changes color to let you know it’s raining to bring in outdoor furniture or displays. Or, a pulsing light for when a delivery arrives but factory noise levels are too high for a doorbell.
Now there are many wireless technology that are applied in Led lighting. Especially Bluetooth, ZigBee and WIFI take a great share in the Market. What are they? And what advantages do they have?
Definition | |
BLE | Called Bluetooth low energy Technology, which is a wireless technology of low cost, short distant transmission and great interoperability,using many intelligent ways to lower the energy consumption to the great extend. |
ZIGBEE | A wireless communication technology at low transmission rates between all sorts of electronic devices in a short range. |
WIFI | A technology lets personal computers, portable devices(PDA or mobile) and so on to connect with each other in a wireless way |
