news digest ♦ LEDs • General: Lighting fixtures (parking garages), light arrays, spotlights Simplified Heat Dissipation = Real Estate & Cost Savings
Because a high-voltage LED (33 volts and up) runs at a lower current, it doesn’t conduct as much heat, simplifying heat dissipation design considerations and ensuring less energy loss in heat generation and control.
The need for bulky heat sync elements is eliminated as the high-voltage LED has a built-in metal core PCB and doesn´t require additional heat sync components. This results in real estate savings of up to 50 percent as well as up to 20 percent cost savings.
Power Conservation & Safety
The current level of an LED is a primary concern because power must be conserved, particularly for power-intensive applications. A low-current unit is also less hazardous than a high current one
Visual Performance Light Distribution
This low-current LED design also offers greater light distribution than traditional standard LEDs that provide light in concentrated area or “hot spot”. A cluster of LEDs offer a viewing angle of 120˚, eliminating hot spot issues.
Brightness
The TitanBrite High-Voltage, Low-Current LED also offers up to 45 percent brighter light output than a traditional 10W LED. With almost double the amount of light in a single unit, the cluster array of LEDs are placed in a unique pattern, that allows the design to achieve this output.
Lumex´s new TitanBrite LED measure 38mm in diameter and feature a 120° viewing angle. They are available in standard cool and warm white as well as custom colours. The technology is competitively priced at $10 to $15 per unit in production volumes, with lead times of ten to twelve weeks.
Osram simplifies LED upgrade for interior lighting
Nearly all surfaces in a car can be individually illuminated with the III-nitride LED modules. All products are wireless, feature four dimming levels and light up in red, blue, green, orange, pink, turquoise or white

Three LED modules enable the individual lighting of various surfaces in the vehicle, and with seven colours.
sram is now providing what it says is the simplest upgrade solution for vehicle interior lighting on the market with LEDambient.
Wallwasher and Spots enable individual lighting of various surfaces in the car
LEDambient modules are battery-operated, so that vehicle interiors can be retrofitted with ambient light without having to route cables. Mounting is carried out simply with a velcro strip or magnets. In addition, all modules feature four pre-set brightness levels and can be operated via remote control.
The portfolio consists of three different LED modules: the door entrance ledge lets door strips radiate in light, activating as soon as the car door is opened.
