LEDs Help Clamp-On Flashlight Deliver Wide Beam & Cordless Operation

The use of LUXEON Rebel LEDs in a clamp-on flashlight recently introduced by Stanley Hand Tools is beaming up big benefits over halogen versions, including a wider beam spread free of hot spots as well as the ability to operate cordlessly with a long battery run time because of low LED power consumption. Stanley used the engineering services of solid state solutions specialist Future Lighting Solutions to optimize the lighting system design.
The hands-free Stanley 95-891 Clamping Flashlight features a floodlight-style beam that was achieved by combining a custom-designed Stanley reflector with the optical properties of the LED package. Comparable halogen products cannot evenly illuminate a large work surface without hot spots. Stanley’s patented 350° rotational head with a 120° tilt can be used to aim the light precisely where it is needed.
Patented Stanley technology also delivers up to 30 hours of run time, eliminating the need to plug the flashlight into an electrical outlet. Halogen versions consume too much power to offer a practical battery option. Future engineers provided optical and thermal simulations as well as LED engineering expertise that assisted Stanley in optimizing the system design and delivering the best performance at the lowest cost without the time and expense of prototyping. Future’s recommendations on LED selection, drive current, heat management, board design and other system components became the blueprint for the finished LED lighting assembly.
Future is also providing a one-stop source for LEDs, boards, drivers and other lighting components as well as supply chain services customized to Stanley’s geographical and logistics needs. Components are stored and shipped from a Future warehouse in China under a bonded inventory program, ensuring reliable parts supply to Stanley’s local contract manufacturer as well as eliminating the lag time that would be involved in shipping from Future’s distribution center in North America.

Philips Unveils World's First LED Replacement for Most Common Household Light Bulb

U-Tron LEDs Bring New Light To Tim's Texas BBQ Beijing

Tim’s Texas Barbecue, a popular restaurant and entertainment venue in Beijing’s central business district, is benefiting from the recent installation of U-Tron’s LED Helios and LED Comet lights, and so is the environment. Helios bulbs were used to replace the original incandescent lights over the restaurants bar and MR16 LED Comet track lights to illuminate stock behind the bar. One benefit of the new lights became immediately apparent to both the staff at Tim’s and their customers. The Helios and Comet lights provide a steady and bright illumination where required, however the light does not spill over to other areas and thus the cozy and intimate ambiance of the restaurant is maintained in the late evening. The low energy consumption of LED lighting is helping to reduce the restaurants power bills and its carbon footprint.
Energy savings are not the only benefit that Tim foresees LED lighting bringing to his business. “Every time we have to change a light bulb there is a labor cost and disruption to our business and inconvenience to our customers. Some lights are in very difficult places to reach, for example over the stairwell. The extremely long life cycle of these LED light bulbs is a significant benefit to us. And, of course, the fact that they contain no mercury and are 100% recyclable is a definite plus.”

Philips Lumileds Brings Best Practices to Analysis of LED Array "Lifetime" Performance

Philips Lumileds has published a new white paper titled Evaluating the Lifetime Behavior of LED Systems that provides the lighting industry with a methodology for evaluating how arrays of LEDs behave over time and how LED luminaire manufacturers can confidently make business decisions such as warranty commitments. The paper goes beyond simple lumen maintenance data which describes how a single LED behaves and addresses the more common lighting system which uses multiple LEDs in a wide variety of use conditions.
An LED luminaire's usable life is determined by a manufacturer's determination of expected lumen maintenance and by the actual usable life of the many components included in the system. Each of the components must be analyzed independently in order to provide an accurate assessment. hilips Lumileds has collected and analyzed over 700 million hours of LUXEON LED reliability test data. Using statistical analysis and models that have long been used and proven in the automotive and electronics industries, Philips Lumileds paper describes how a luminaire manufacturer can define the "lifetime" of the LEDs in a system and understand how to scale from the behavior of one LED to many LEDs. This is an essential process for anyone that is developing product warranties and results in clear understanding of "lifetime" of the LEDs.
