Osram is aiming at torches and work lamps with a long-life 160 lm LED.

Called Osconiq P 3030, it is build around a 1 x 1mm die that can be driven at 1.3A and comes in a specially-developed 3 x 3mm (1.63mm high) SMD epoxy package with lead-frame heat spreading and a silicone lens.

“Compared with the ceramic packages commonly used in this field, Osram’s new package provides a more robust component with a longer lifetime,” claimed the firm, which is specifying the part at 70,000h life.

The firm has been using similar packages in other sizes for several years, for example: 2W and 3W 3.7 x 3.7mm versions (Osconiq P 3737) – the 3030 is nominally a ‘1W’ design. In a video, it claims that the packages are “as resistant to heat and corrosion as ceramic LEDs”.

The 3030 will be available in two CRI versions: 70 and 80.
CRI 70 types will span 2,700 to 6,500K, while the CRI 80 version will cover 2,200-5,000K.
The only two devices that the company is releasing figures for are:

• GW QSSPA1.PM: 5,000K 70CRI 160 lm and 160.4 lm/W
• GW QSSPA1.EM: 3,000K 80CRI 133 lm and 133 lm/W

Both at 350mA and Tj=85°C

Other figures are:

• 120° FWHM viewing angle
• 2.85V typical drop (30mA 85°C)
• -40°C to 125°C operation, 135°C max at junction
• junction-solder thermal resistance 80CRI type 5.4K/W (ηe=40%)
• junction-solder thermal resistance 70CRI type 4.9K/W (ηe=46%)

Where ηe is the external quantum efficiency, provided by Osram.

“Thanks to a universal contact pad design [right], previously-used ceramic components can be replaced easily,” said Osram product manager Boo Hian Voon.

Colour versions are planned for horticulture and outdoor lighting: deep blue (450nm), blue (470nm), true green (528nm), red (623nm), hyper red (660nm) and far red (730nm).

The robustness claim is through chemical resistance, with Osram rating the LEDs ‘Class 3B’ with a test “stricter than IEC60068-2-43” – the figures are 40°C, 90% RH, 15ppm H2S, 14days.

Despite robustness claims, according to the data sheet the package not suitable for ultrasonic cleaning.
