The new ultra-white OSLON SSL LED from OSRAM Opto Semiconductors may be small in size, at only 3 x 3 mm, but it's big on performance. Using the latest chip technology, the 1 W OSLON SSL LED achieves impressive brightness and high luminous efficiency of 100 lm/W.
The new OSLON SSL LED can be used as a replacement for halogen lamps in spotlights, desk lights and reading lights and can also be used in various retrofit applications. Picture: OSRAM
The OSLON SSL LED meets the required standard for general lighting usage and is reliably efficient even at high currents and thanks to its beam angle of 80° it is perfect for injecting light into external lenses. The OSLON SSL LED is ideal for spotlights, desk lights and ceiling floodlights
“Its ability to handle high currents efficiently enables our customers to create energy-efficient and cost-saving lighting solutions. The OSLON SSL LED has all the attributes to become the ‘green’ light source of the future,” said Brian Terao, Director of SSL at OSRAM Opto Semiconductors, Inc.
The OSLON SSL LED has a low thermal resistance of 7K/W, which simplifies thermal management. Its compact size gives designers the flexibility to create extremely sophisticated solutions and in designs where more light is needed, several OSLON SSL LEDs can be combined to form a cluster. In addition to ultra-white (5700 to 6500 K), the LED will be available this summer in neutral white and warm white with a color temperature ranging from 2700 to 4500 K.
Manufactured with the latest chip technology, the OSLON SSL LED has an operating current of 350 Ma, which enables the light source to achieve a typical brightness of 110 lm in ultra-white (5700 and 6500 K), and a maximum possible luminous flux of 130 lm at present. At an operating current of 350 mA and a color temperature of 3000 K, the OSLON SSL LED can achieve efficiency of 75 lm/W and a brightness of 85 lm. Additionally, brightness is a remarkable 155 lm at an operating current of 700 mA (warm white). At these performance levels, the OSLON SSL LED can meet the demand for high-lighting levels using fewer LEDs with currents up to 1A.
