ON Semiconductor Connected Lighting Platform
Speeding up the design of industrial LED lighting.
ON Semiconductor has launched the Connected Lighting Platform, a modular kit which supports the development of energy-efficient or batteryless LED lighting solutions. The platform, which is easy for lighting equipment manufacturers to use in product design projects, supports wired and wireless connections to LED lighting via an Ethernet or Bluetooth® Low Energy network.
In creating the Connected Lighting Platform, which has the part number LIGHTING-1-GEVK, ON Semiconductor has drawn on technologies and products which are widely used in the industrial and commercial sectors. These include the RSL10 System-in-Package (SIP), an integrated Bluetooth Low Energy radio system. The RSL10 SIP reduces time-to-market by eliminating the need for the user to implement a discrete antenna circuit. The ready-to-use RSL10 SIP features an integrated antenna, RSL10 radio System-on-Chip (SoC), and all passive components in a single, miniature package.
The Connected Lighting Platform also features an LED driver board based on the ON Semiconductor FL7760, an efficient step-down controller for lighting applications which operate in Continuous Current Mode (CCM). The FL7760 can operate from an input ranging between 8V and 60V DC. It supports both 12-bit PWM and analog dimming via its Dim pin, dimming down to 0.025% of full brightness.
In the Connected Lighting Platform, the FL7760 driver board is fed by either an AC-DC power supply or via Power over Ethernet (PoE). The AC-DC converter board operates from a universal mains input-voltage range and produces an output of 55V DC to support loads up to 70W. The AC-DC converter’s power factor is >0.99 at full load. The power system achieves conversion efficiency of better than 90% at full load.
A PoE power module, the LIGHTING-POWER-POE-GEVB, is available separately to provide Ethernet connectivity and a power supply to the LEDs of up to 90W at efficiency of more than 99%.
The power and control boards drive an LED module which consists of independently controlled strings of 16 warm-white and 16 cool-white LEDs. In total, they produce a maximum light output of 7,000 lumens.
The Connected Lighting Platform provides several ways to implement LED control, including the RSL10 Sense and Control mobile app. Available for the iOS® and Android™ mobile operating systems, the app can be used to control LED functions such as dimming, on/off and telemetry, and to monitor power consumption.
Firmware Over The Air (FOTA) updates can be easily sent through the RSL10 FOTA app. A comprehensive development environment, including a CMSIS-Pack featuring customizable firmware and the FreeRTOS™ operating system, supports the platform. It can also be used with an energy harvesting Bluetooth Low Energy switch to develop batteryless applications.
