Osram unveils first filament LED to replace incandescent lamps
The Soleriq L 38 LEDs offer a uniform color appearance and quality of light, creating a pleasant atmosphere which makes them ideal for aesthetic lighting applications in the home and in hotels and restaurants.
Each Soleriq L 38 has a length of 30 mm and a diameter of 1.8 mm. The shape, which is similar to that of a conventional filament, plus an emission angle of 360 degrees and their quality of light make them suitable for use in LED lamps of all wattages that mimic the appearance of classic light bulbs. Soleriq L 38 LEDs are offered in different MacAdam groups according to their color, forward voltage and brightness – at a temperature of 85°C which closely approximates to the temperature in the application. Filament LEDs therefore have a uniform color appearance and quality of light.
Sorting by forward voltage enables multiple LED filaments to be connected in parallel, resulting in reliable operation with no overloading of individual filaments.
Like all Soleriq products, the L 38 offers high brightness and is available in three versions with 90, 130 or 140 lumen. The values enable all previous lamp wattages up to 60 W to be replaced with equivalent LED filament solutions. The driver voltage needed for the LED filament lamps can also be adjusted. All the versions have an extremely high luminous efficacy of 150 lm/W and provide warm white light (2500 to 4000 Kelvin). Thanks to the good color rendering index of over 80, the new Soleriq is ideal for indoor lighting, particularly in the home. The main applications include products with a traditional look and modern interior, such as classic glass bulbs with LED filaments.
