LEDs ♦ news digest
2-lead, TO-66 electrically-isolated packagense are gold plate. Operating and storage ranges are - 40 to +100°C.
Opto Diode, a division of ITW, and a member of the ITW Photonics Group, has launched the OD-669-850 high-power AlGaAs infrared IRLED illuminator.
Ideal for night vision illumination tasks, the infrared illuminator features ultra-high optical output, from 800 (minimum) to1250 mW (typical) and a peak emission wavelength of 850nm.
Opto Diode’s new device provides a uniform optical beam. The spectral bandwidth at 50 percent is typically 40 nm, and the half-intensity beam angle is 120 degrees. All surfaces on the standard 2-lead, TO-66 electrically-isolated package are gold plate.
The OD-669-850 IRLED illuminator’s operating and storage temperatures range from - 40 degrees C to +100 degrees C with a maximum junction temperature of 100 degrees C.
Power dissipation (under absolute maximum ratings at 25 degrees C) is 6 W, with a continuous forward current of 370 mA, a peak forward current of 1A and reverse voltage at 5 V. The lead soldering temperature (at 1/16 in. from case for 10 seconds) is 2600C.
Opto Diode Corporation, is a member of the ITW Photonics Group and delivers standard and custom photodetectors, and reliable, high quality, standard and custom infrared and visible LEDs.
The company, with the recent acquisition of International Radiation Detectors, also designs and manufactures semiconductor radiation devices that detect photons in the UV range, X-rays, and other high energy particles. The domestic U. S. manufacturing plant includes a wafer fab and ensures delivery of volume quantities at competitive prices with short lead times.
Opto Diodes works in a variety of industries, including test & measurement, biotechnology, medical, entertainment, military and defence, industrial, aerospace, automotive and R&D sectors.
The ITW Photonics Group was created to bring together and build on the technical expertise of three individual companies that specialise in photonics technology and span a spectrum of wavelengths.
LED light bulbs could be a shock hazard
Consumers have been advised to stop using Philips’ Endura and Ambient LED dimmable light bulbs unless otherwise instructed
Although no injuries have been reported, the U.S. Consumer Product Safety Commission is recalling Philips’ Endura and Ambient LED dimmable light bulbs.
The bulbs have been sold at Home Depot, grocery and home centre stores nationwide, online retailers, including Amazon. com and through electrical distributors between October 2012
August/September 2013

Image depicting EnduraLED and Ambient LED dimmable light bulbs
The date codes, 2L for the Endura bulbs and 2K or 2L for the Ambient bulbs, are printed on the metal screw base. The bulbs give off a white light and are used indoors to replace incandescent bulbs. The following chart outlines the recall details:
The main issue is that a lead wire in the bulb’s housing can have an improper fitting, which can electrify the entire lamp and pose a shock hazard.
Consumers have been recommended to immediately stop using the recalled LED bulbs, unplug the fixture, remove the bulb and contact Philips for free replacement bulbs.
Philips Lighting can be contacted on (800) 295-5147 between 9am and 5pm ET from Monday to Friday and can also be reached online at
www.recall.philips.com.
So far the units related to is about 99,000.
This recall involves Endura 12-watt and Ambient 12.5-watt LED dimmable light bulbs. The bulbs are orange in colour and have “MADE IN CHINA,” “Fabrique in Chine” followed by a slanted “S,” and the model number 9290001829 printed on the grey plastic band on the neck of the bulbs.
