Standard LED Platforms

Standard LED-Based Lighting Platforms

At OptoElectronix, we define LED-based lighting platforms as containing the following:

• A unique form factor
• An optical system (lens)
• An electronic drive circuit that drives the LED from a standard voltage source
• A thermal management system for the LED-generated heat
• And, of course, an LED.

Sample Standard Platforms

Universal Light Engine™ Platform, ULE2000 Series

• Form factor: 40mm circular disk, 1.5-3.5 watts of LED light (equivalent to 6-14 watts from an incandescent bulb)
• Optical system: interchangeable lens such as flood, spot, or cylinder
• Drive circuit: 12VAC or 12VDC
• Thermal management system: designed to efficiently deliver the generated heat to the IPS pipe threads at the back of the light engine
• Accepts LEDs from most major manufacturers

Applications for the ULE2000 LED light platform include landscape lighting, appliances, off-road vehicle headlights, and general-purpose lighting.

Flush-Mount LED Lights

Flush mounting is ideal for “through the wall” applications in appliances where the light is lighting a hostile environment, such as extreme cold. The light engine is protected from the hostile environment because it is on the protected side of the wall. Applications include refrigerator or freezer lights as well as cook-top hood lighting. Other applications include marine and bath/shower lighting, where the LED needs to be protected from moisture.

Multiple-LED, Planar Platform

Multiple LEDs arranged on a plane provide ample light for applications such as wall sconces or outdoor wall lanterns, providing a huge opportunity for design innovation. Form factors include rectangular, circiular, or linear. The driving circuitry for a multi-LED approach handles standard 120VAC line voltage. Heat sinking can be direct to the fixture via an IPS connection.

Why Standard Platforms?

The idea of standard LED lighting platforms that handle multiple applications means that sales volumes of the platforms will be high enough to allow high-volume, automated manufacturing to bring costs down and quality up. Yet the versatility of the platform approach gives lighting and luminaire designers infinite design freedom.
