BivarOpto has introduced a new wedge-based warm-white LED featuring accurate colour output of industry standard T-1 ¾ (5 mm) wedge-based incandescent bulbs. The ability to imitate the same output brightness and hue as the incandescent lamp opens many new doors to a host of applications where longer life LEDs can lower replacement and overall systems maintenance costs.
Typical applications for this LED device include telecoms, switching systems, elevators, automotive instrument panels, annunciators, indicators and use in miniature lighted pushbutton switches. Indoors, it can enhance warm earth tones and provide visual illumination that the company claims is not only comfortable to the eye but organic and transparent compared to the harsher tones of typical solid-state 'white' LED lamps.
The WB5 Series features a warm-white colour temperature of 3500 K (Kelvin) and has a flat faced lens design with an internal reflector for enhanced light intensity while also providing a 180° wide-viewing angle. Rated at 2,5 V d.c.-48 V d.c., the subminiature unit measures 20,37 mm in length and 5,842 mm in diameter. It is rated for service life up to 100 000 hours, and requires 10-30 mA typical current.
