Sunlight-Visible Wedge Based LED Clusters Replace Incandescents, Deliver Improved Illumination and Durability
05-OCT-99


TORRANCE, CA — October 5, 1999 — LEDtronics announces a family of sunlight-visible Wedge Based Direct Incandescent Replacement LED cluster lamps that are plug-compatible for fragile, short-lived incandescent lamps. These innovative LED products replace standard wedge-based incandescent lamps in miniature switches, indicators, annunciators and other applications where complete compatibility, durability and efficiency are needed. LED cluster lamps last 10 - 20 times longer than the incandescent lamps they replace, and their low-current, high-efficiency operation delivers power savings of 80% - 90% or more.

These LEDtronics® products are ideal for 2-4 lamp lighted push-button switches where vibration, shock and heat reduce the service life of incandescent lamps. LED clusters are solid-state devices that feature very fast turn-on and turn-off times without transients. A typical Wedge base LED cluster draws 15-20mA compared to the 40-60mA required by a miniature incandescent lamp.

Wedge Based LED lamps are plug-compatible with illuminated switches and indicators from most major manufacturers. Wedge based LED lamps are available for all common indicator voltages from 5V to 120V DC or AC (50-400Hz). The products feature built-in current-limiting resistors and polarity-protection diodes to assure that circuit modifications are not required. Choose from nine standard LED colors (red, orange, amber, yellow, lime-yellow, green, pure-green, blue and white) and a variety of voltage ratings. Direct replacements are available for the most popular wedge-based incandescent lamps (17, 18, 37, 56, 73, 74, 79, 84, 85, 86 etc.). Unique configurations of bi-color, blinking, infrared, ultra-bright or very low current LEDs are available by special order.

Miniature wedge based LED lamps T1-3/4 (5mm) package profile range from .70-inches (17.78mm) long to .230-inches high (5.842mm) and .80-inches (20.33mm) long and .230-inches high (5.842mm).

Solid-state design renders Wedge Based LEDs impervious to electrical and mechanical shock, vibration, frequent switching and environmental extremes. A typical LED cluster lamp contains one to six solid-state emitters arranged to provide an intense beam of colored light. The emitter arrangement provides a very wide viewing angle or 160 degrees (spherical). Unlike a single-filament bulb, an LED cluster lamp continues to provide illumination even if one or more of the multichip emitters fail. Colored lenses or filters are not needed since LED cluster lamps emit colored light. The intensity and wavelength remain stable over the lamp’s lifetime of 100,000-plus hours. (That’s 10-20 times longer than incandescent bulbs!) Additionally, Wedge Based LEDs are environmentally friendly because they use 80% to 90% less operating power than standard incandescent bulbs. Think of the savings from reduced power usage, maintenance costs and less downtime!

Founded in 1983, LEDtronics® leads where others only follow when it comes to designing, manufacturing and packaging state-of-the-art LEDs to meet the world’s constantly changing lighting needs. Our inventive product line encompasses an array of direct incandescent lamp replacement Based LEDs, low-cost snap-in and relampable Panel Mount LEDs, high intensity sunlight-visible Discrete LEDs, PCB LEDs circuit board status indicators, surface mount diodes SMT LEDs, full-spectrum rainbow RGB LEDs and Infra-Red (IR) LEDs.

Samples are available to qualified customers. A 28VDC Red polarized version is priced at $2.89 per unit in 1000 piece quantity. Data sheets are available.
