History

LumiLeds Lighting B.V. was formed in November 1999 as a joint venture between Philips Lighting and Agilent Technologies, a spin-off of Hewlett-Packard. At the time of formation, it was an equal partnership with each company owning a 50% share in Lumileds Lighting.. In August 2005, Philips acquired a controlling stake in Lumileds when it purchased Agilents 47% share of the company for USD $950 million. This resulted in Philips owning 96.5% of the company with the remaining 3.5% owned by employees.. In December 2006/January 2007 Philips acquired the remaining 3.5% of the company, making Lumileds a fully-owned subsidiary of Philips Lighting.

Products

Lumileds develops and markets high-powered and high-efficiency LEDs for a wide range of uses. The products are grouped into the Luxeon, SuperFlux and SnapLEDs lines of LEDs. Unlike SuperFlux and SnapLEDs, the Luxeon line of LEDs has multiple sub-families based on package, efficiency and output.

Lumiled products are used in general lighting, automotive lighting, portable lighting, digital imaging, display backlighting, signal and signage applications.. As with most manufacturers who produce LEDs for the OEM market, Lumileds products are binned according to wavelength, luminous flux(output) and forward voltage. By binning the LEDs they produce, manufacturers ensure that someone can purchases a specific LED and bin from them and know that all LEDs from that bin will operate and appear essentially identical to each other. While not an issue for applications using single LEDs. When multiple LEDs are used in an array, such as automotive taillights, it becomes essential that the LEDs not only appear identical but behave identical to one another. (Note, however, that Lumileds have sufficient output and directionality that automotive tail and indicator lights need only use a single device, avoiding the complication and cost of an array; only a single Luxeon I is needed to produce a visible result equivalent to the poorly-directed, colour-filtered 21W incandescent bulb which is historically used for this application.)

Luxeon

Luxeon is Lumiled's trade name for their high-power LEDs which dissipate 1 watt or more. Models include Luxeon I, Luxeon III, Luxeon V, Luxeon K2, Luxeon Star, Luxeon Rebel, Luxeon Flash, and Altilon. In 2009, Lumileds announced that the Luxeon I/II/III/V and K2 lines are unavailable for new designs, and will be replaced by the Rebel series. Luxeon LEDs produce high light output from single emitters, and are a popular choice among flashlight manufacturers. They are also commonly used in automotive lighting applications, most notably in the white DRLs of the Audi S6 and reverse lights of the Cadillac DTS.

Luxeon I

These were the original high-powered LEDs produced by Lumileds, rated for power dissipation of approximately 1 watt. They consisted of an emitter, an anode, a cathode, a circular base and a lens all integrated into one round package (excluding the anode and cathode which exit the sides of the case). These LEDs were intended to be surface mounted on a metal-core PCB and often required a heatsink due to the large amounts of heat produced. The thermal pad was not electrically isolated, and floated at a voltage in between the anode and cathode.

Luxeon I's were available in Cool White, Warm White, Green, Cyan, Blue, Royal Blue, Dental Blue, Red, Red-Orange and Amber.

Luxeon III

Operating at approximately 3W, these had a higher luminous flux than a Luxeon I, though less than a Luxeon V. They were a compromise between cost and output.

Luxeon III's were available in Cool White, Green, Cyan, Blue, Royal Blue, Red, Red-Orange and Amber.

Luxeon V

Lumiled's Luxeon V LED's disspated 5 watts and produced approximately four times the lumen output of a Luxeon I, in a package of almost the same size.

Luxeon V's were available in Cool White, Green, Cyan, Blue, Royal Blue and Dental Blue (a near-ultraviolet wavelength for curing dental adhesives).

Luxeon K2

These were the highest output Luxeon emitters produced, with single-emitter flux of up to 200 lumens at 1500mA. They produced more light than the Rebel line which replaces them. The new Altilon line produces more output per device, but barely exceeds the K2 in lumens per die. The K2 was the first Luxeon product to allow the use of FR-4 PCB material instead of metal core, but only at reduced current or under exceptionally favorable thermal conditions.

Luxeon Rebel

These are the smallest Luxeons available, yet they are rated for 700 to 1000mA and produce around 140 lumens at full current. The LED package is a 3mm X 4.5mm surface-mount ceramic chip with two electrical pads and an electrically isolated thermal pad. Unlike previous models, the Rebel can be used on a standard FR-4 circuit board at full current by creating an array of thermal vias to carry heat to a heatsink on the back side of the board. The Rebel is intended to replace all prior Luxeon models, which are no longer available for new designs. The Luxeon Rebel White is available in a range of shades of white, instead of the normal warm and cool white, and is available binned by color rendering index. The Luxeon Rebel Color is available in Green, Cyan, Blue, Royal Blue, Red, Red-Orange and Amber.

Luxeon Star

Luxeon stars are Luxeon emitters mounted on a star shaped metal-core PCB. They are available with any of the Luxeon emitter types, and are intended to simplify the integration process for users who do not want to design and manufacture metal-core PCBs and engineer thermal solutions for the LEDs.

Luxeon Altilon

The Luxeon Altilon series is the newest line of high power LEDs, intended specifically for automotive lighting. These LEDs are packaged multiple-die devices with ratings up to 850 lumens at 1000mA and an extended temperature range up to 130C.

Luxeon Flash

Luxeon Flash LEDs are intended to replace xenon flash units in digital cameras. These LEDs are designed for high lumen output from a small package, but not for continuous operation.

SuperFlux

SuperFlux is the trade name for a line of through-hole mounted high-output LEDs. These LEDs are intended for automotive tail-light and warning sign applications. The only colors available are Blue, Green, Cyan, Red, Red-Orange and Amber. The package has a distinctive square shape often copied by other manufacturers who call it a Piranha LED. Lumileds SuperFlux run at 70mA current (except for blue, green and cyan which run at 50mA current) and have a forward voltage of 2.0 to 5.0 (depending on color and bin).

SnapLEDs

These LEDs are quite similar to the SuperFlux LEDs in shape, except that instead of having 4 pins, they have fins on the side that are meant to be crimped using a special tool. These fins are designed to allow for both better heat dissipation and also allow solder-less assembly of components. Due to the increased heat dissipation, SnapLEDs are available in a higher current form called the SnapLED 150 (max. current of 150mA). These LEDs are intended for use in automotive applications, they are only available in red-orange and amber.
