NORTHVILLE, Mich., July 18, 2011 — The compact TopLEDs from Osram Opto Semiconductors Inc. feature integrated lenses in black packages and are now available not only in red and yellow, but also in blue, green and orange. The company has added the three new colors to its TopLED Black series 60° beam angle portfolio. Also new is a 30° beam angle version available in all five colors.
The LEDs are suitable for monochromatic and multicolor displays used in variable message signs, such as electronic traffic management road signs; travel information displays in airports, and in railway and bus stations; parking control systems; and gas price signs. The most suitable beam angle for each of these applications depends upon local conditions and upon the distance that a sign is from the viewer. On straight roads, the LEDs with a 30° beam angle can be used, whereas a 60° beam angle is better for the curved entries and exits of highways and gas stations and for applications such as bus destination displays. The orange LED versions are intended for use in pedestrian signs.
The completely black package of the TopLED Black series reduces reflections considerably. The LEDs also offer high contrast so that displays are legible in all lighting conditions. The 30° version of the green LED offers 7-cd luminance at an operating current of 20 mA.
All TopLEDs are surface-mount-technology components suitable for automated handling so that displays can be manufactured at lower cost than can those with radial LEDs. The solder pads are compatible with other TopLED and Power TopLED devices, providing flexibility. Design change can be accomplished easily, meaning that displays can be made with different luminances and beam angles on a single circuit board.
