ON Semiconductor Connected Lighting Platform
Speeding up the design of industrial LED lighting
ON Semiconductor’s Connected Lighting Platform is a modular kit which supports the development of a highly efficient LED power, control and dimming circuit. The platform supports wired and wireless connections to the application 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 0.6% of full brightness.
The FL7760 driver board is supplied by an AC-DC converter board which 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 Power-over-Ethernet (PoE) power module, the LIGHTING-POWER-POE-GEVB, is available separately to provide reliable, high-power Ethernet connectivity and a power supply to the LEDs of up to 90W at efficiency higher than 99%. The PoE power module is powered by ON Semiconductor’s NCP1096, an Integrated PoE-PD interface controller which complies with the IEEE 802.3bt, IEEE 802.3af and IEEE 802.3at standards. The NCP1096 includes all the functions required in a PoE system such as detection, classification and current limiting during the inrush phase.
The Connected Lighting Platform’s 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 for the iOS and Android™ mobile operating systems, or a web client. The platform is supported by a comprehensive development environment, including a CMSIS-Pack featuring customizable firmware and the Free RTOS operating system.
