The new IR OSLON SFH 4715S from OSRAM Opto Semiconductors is the smallest infrared LED on the market with more than one watt of optical power. Measuring only 3.75 x 3.75 mm², it enables the development of exceptionally compact illumination units for CMOS and CCD cameras. This record-breaking high performance in such a compact device is possible thanks to OSRAM’s nanostack chip technology combined with a temperature-stable OSLON Black Series pa...

In the design of a driving circuit for LEDs, the dimming behaviour is an important topic to fulfil the end customer requirements. The intend of this application note is to describe the behaviour of LEDs in respect to brightness by varying the current and to suggest solutions for avoiding negative influence for the application.

Some year s ago, the color range of Light Emitting Diodes ( L EDs) on the market was limited to the red to green spectrum. Then, blue LEDs were developed and introduced into the market . These blue devices made it possible to build so called “ single- chip white ” LEDs, using a yellow converter material in combination with a blue die. Most of the blue and white LEDs use Indium Gallium Nitrite (InGaN) as an epitaxial layer.

Smallest 5W Power LED

Super low-profile and incredibly powerful – these are the demands that touch screens place on infrared components. And that’s no problem for the new CHIPLED SFH 4053: Its tiny dimensions make it one of the smallest on the market. Combined with its high performance the CHIPLED is ideal for low-profile all-in-one computers and laptop displays. And the IRED is so small that it can be easily integrated in smartphones.

Touch screens demand infrared components that are super low-profile and extremely powerful. The new ChipLED SFH 4053 infrared emitter (IRED) from OSRAM Opto Semiconductors combines tiny dimensions with high efficiency, making it ideal for low-profile all-in-one computer, tablet PC and laptop displays. And the new IRED is so small that it can be easily integrated into smart phones as well.

The small powerful LEDs in black packages are now available not only in red and yellow but also in blue, green and orange. OSRAM Opto Semiconductors has added three colors to its TOPLED Black Series 60° beam angle portfolio and now offers all five colors with a 30° beam angle. “This means that we have the broadest portfolio of ‘black’ LEDs on the market and can cover a wide range of applications”, said Product Manager Sven Weber.

Compact and powerful TopLEDs from OSRAM Opto Semiconductors featuring integrated lenses in black packages are now available not only in red and yellow but also in blue, green and orange. Osram added the three new colors to its TopLED Black Series 60° beam angle portfolio. Also new is a 30° beam angle version available with all 5 colors. “This means that we have the broadest portfolio of ‘black’ LEDs on the market enabling a wide range of ...

A fast laser diode of OSRAM Opto Semiconductors provides light for the new 3D camera of the Swedish manufacturer FOTONIC. The component has been developed specially for 3D cameras like the FOTONIC C70. It facilitates range finding for moving object with good depth resolution at video rate

The new product family in the low-power range from OSRAM Opto Semiconductors starts with DURIS E 3. The small dimensions and wide beam angle of these new LEDs make them ideal for applications that require uniform illumination. These highly efficient LEDs can be used as replacements for conventional fluorescent lamps in T5 or T8 luminaires for example.

Warm white light with a high luminous efficacy (110 lm/W) and a color rendering index (CRI) of more than 90 are the result of the new “Brilliant-Mix” concept from OSRAM Opto Semiconductors. The intelligent color mix based on powerful OSLON SSL LEDs in EQ-White and Amber covers a broad white spectrum from 2700 to 4000 K. Depending on the required luminous flux, a different number of these LEDs can be combined to produce warm white feel-good li...

OSRAM Opto Semiconductors OSLON SSL LED, standard (80-degree) and wide angle (150-degree), is the first power duo with sophisticated radiation patterns. Highly Compact, High Efficiency, High Power.

With the help of “Light Line”, a warning light installed in the pavement, crossing the road becomes safer for pedestrians. Working in parallel to the switch function for the standard traffic light, “Light Line” uses a red or green signal to show when the street can be crossed safely and without danger. This new warning light was developed by DSTA, a Spanish company that designs and manufactures LED solutions for traffic lighting and trans...

OSRAM Opto Semiconductors was an award winner at the 17th Annual Automotive News PACE Awards for innovation held at a black tie ceremony last night at the Max M. Fisher Music Center in Detroit, Mich. The award was accepted by Peter Knittl, LED automotive director at OSRAM Opto Semiconductors.

OSRAM Opto Semiconductors provides LED lighting for three Beijing districts. LED technology in street lighting is on the advance across the world. As part of the Chinese 10 cities 10,000 lights project, three districts in the capital Beijing were equipped with LED street luminaires by the HBTechnology CAST Group, using OSLON SSL LED by OSRAM Opto Semiconductors. They ensure that the busy streets are brightly lit and save up to 50% in energy comp...

Streetlighting with LED is getting more popoular every day - due to the technical features of the tiny light source. LED are very energy efficient, offer high light quality and a long lifetime.

An impressive OLED installation by the lighting planners of ‘LichtKunstLicht’ is the main attraction on the OSRAM stand at the Light + Building show in Frankfurt from 11 to 16 April 2010. Design objects and luminaires use actual examples to show the range of wafer thin light sources with various colors and shapes.

They ensure that the busy streets are brightly lit and save up to 50% in energy compared with conventional luminaires.

OSRAM Opto Semiconductors has set a new laboratory record of 142 lm/W for the efficiency of a warm white LED light source. With a correlated color temperature (CCT) of 2755 K the LED achieves a good color rendering index (CRI) of 81. Measurements were taken under standard conditions: room temperature and pulsed mode at an operating current density of 350 mA/mm².
