The Oslon Square, OSRAM Opto Semiconductors’ new LED, offers a wide range of possible uses, including designer luminaires for the home or office, retrofits and street lights.
The LED is available in many different versions with different color temperatures. It can be operated with different currents, making it extremely versatile. Its reflective package makes even better use of the light and increases system efficiency in all versions. The Oslon Square is available at distributor Rutronik now.

The Oslon Square measures only 3mm x 3 mm, has a low thermal resistance of 4K/W to 3.8 K/W and is accommodated in a robust package which is suitable for outdoor use. The LED chip is enclosed by a reflective package that reflects light emitted at the side or at the back so that this light is usable. The Oslon Square EC is suitable for indoor applications in which a high quality of light is needed, for example in offices. With a color temperature of 3000K it provides a warm white light and also offers high color stability over a wide viewing angle (120°). The CRI is at least 80.
If the lighting needs to be particularly uniform a “fine-bin” order can be placed for this LED. At an operating current of 700mA it achieves an efficiency of above 90lm/W and a luminous flux of 200lm and more. At 350mA its efficiency passes the 100lm/W mark. The EC version is also suitable for retrofits. Thanks to its small dimensions it can be closely clustered and, like all the LEDs in this series, it benefits from its reflective package, both individually and within a system.

The Oslon Square PC and UW are designed for outdoor applications, i.e. in street lighting. They can be operated on currents of 200mA to 1.5A, making them interesting for other applications such as downlights and spotlights. The LEDs produce a neutral white to cold white light with color temperatures of 4000K and 6000K. And at 130lm/W from 350mA they are even more efficient than the warm white version. With a CRI of at least 70 (4000K) and 65 (6000K) these LEDs combine good quality of light with high efficiency.

The new Power Topled with lens (SFH 4258S/4259S) from OSRAM Opto Semiconductors has an 80 percent higher optical output than the standard version of the infrared LED – despite the same surface area and the same current. This boost comes from a special thin-film chip which, thanks to Nanostack technology, has not just one but two p-n junctions that are grown one on top of the other. The resultant increased range will above all benefit applications in the security sector and in gesture recognition. The new Power Topled is now available at distributor Rutronik.

Apart from the Nanostack chip and the associated higher output the new infrared Power Topled is the same as the standard version and can therefore be used as a simple direct replacement. The package dimensions (footprint) remain the same so existing designs can continue to be used. Because of the series circuit the voltage is higher by about factor 2. The infrared Power Topled produces an optical output of 80mW from an operating current of 70mA – around 80 percent higher than the standard model from the same current. The new LED emits at a wavelength of 850nm and is therefore a good compromise between maximum spectral sensitivity for CCD and CMOS cameras and suppressed visibility for the human eye. It is available with beam angles of +/-15° (SFH 4258S) and +/-25° (SFH 4259S) from two different lens types. The new LED is particularly useful for infrared illumination, especially in security systems. In CCTV applications the range can be increased significantly with the same number of LEDs. The main area of application in the consumer sector involves camera-based gaming as this is where high optical output has the greatest benefit.

Farnell has added three new designs of LED lighting connectors to the range of products it offers from interconnection specialist JAE. The agreement between the two companies, which includes an exclusivity period of six months, will see Farnell become the first European distributor to stock the ES3 series.

Offered in a choice of PCB card edge (Cableless), wire-to-board (cable insertion), and discrete wire clamp formats, the ES3 series provides an efficient method of achieving interconnections between LED mounting PCBs and other circuitry in LED module designs. All three connector formats are manufactured from a durable high temperature resin and are designed for surface mounting.

With a low-profile mounted height of just 1.6mm, ES3 LED lighting connectors are well-suited to space constrained designs. By allowing a cableless design, both the number of parts required and the time to complete assembly can be reduced. ES3 LED lighting connectors are rated to 1A and have an operating temperature range of -40 º C to +105 º C.

The new connectors complement the wide range of solid state lighting products already stocked by Farnell and featured, along with comprehensive supporting information, on the company’s Lighting Solutions microsite.

GradConn Interconnect recently introduced the BB02-xF series U-Shaped thru hole connectors for planar PCB mating with 2.00mm pitch spacing.

These U-Shaped one piece headers are available in single in line or dual in line and provide an economical option for a one piece ‘fit and forget’ solution, either solder direct into the PCB or use a vertical socket on each PCB if access space is tight and retro fitting the connection from above is desirable.

Alternatively plugging to vertical PCB sockets is particularly effective in applications where assembly space is limited allowing headers to be retro fitted after LED lighting strips are in place. The BB02-1F and 2F offer customizable space between pins and pin height. For more information on these and other GradConn products contact Texim Europe.
