ABSTRACT:
A component device for optical communication comprising a reflector and a lens. The reflector is in the form of a deep dish with a height B of 0.2-0.4 mm, a bottom diameter A of 0.7-1.1 mm and the side wall having an angle C of 40-85 degrees. The lens is a hemisphere formed on the reflector, with the apex distant from the bottom surface of the reflector by a height D of 4.5-5.0 mm. The hemisphere has a radius R of 2.4-2.8 mm. A thin miniature lamp is provided that is improved in leadframe design such that the advantages of the conventional 5 mm.sup..phi. are retained, while its height is reduced to less than 5.5 mm. In addition, it is capable of achieving an effective luminous intensity distribution pattern of a light beam, which is one of the major characteristics required in data communication.
