A coil filament in which the volume is reduced as much as possible at the light emitting part in order to reduce the size of a bulb while enhancing the illuminance of illumination light field efficiently. A flatly wound flat coil filament (1) is arranged spirally or annularly such that the axis FL in the long side direction is in parallel with the central axis CL of the coil filament or intersects at an appropriate angle .alpha. including right angle, or arranged while aligning with the radial axis HL of the coil filament or at an appropriate angle .alpha. including the radial axis HL. Alternatively, the flat coil filament is formed into U-shape and a pair of U-shaped flat coil filaments are inserted mutually from the open end such that the inside of each closed end is in noncontact state, or the flat coil filament (1) is formed into a circle and, within the range of circle of circular double coil filaments (5, 10, 12), an appropriate number of linear or circular flat coil filaments (6, 7, 9, 11, 13, 14) are arranged in the direction of the central axis CL of the circle.

L'invention concerne un filament dont le volume a été réduit au maximum au niveau de la partie luminescente afin de réduire les dimensions d'une ampoule tout en augmentant efficacement l'éclairement du champ lumineux. Ce filament est un filament plat enroulé à plat (1) disposé en spirale ou de façon annulaire de façon que l'axe FL dans le sens de la longueur soit parallèle à l'axe central CL du filament ou croise l'axe central CL à un angle approprié .alpha., y compris à angle droit, ou disposé de façon alignée par rapport à l'axe radial HL du filament ou à un angle approprié .alpha., y compris l'axe radial HL. Le filament plat peut également être conçu en forme de U, une paire de filaments plats en forme de U étant introduits mutuellement par une extrémité ouverte de façon que l'intérieur de chaque extrémité fermée ne soit pas en contact. Le filament plat (1) peut également être conçu sous forme de cercle, un nombre approprié de filaments plats linéaires ou circulaires (6, 7, 9, 11, 13, 14) étant disposés dans le sens de l'axe central CL du cercle, dans le cercle de filaments doubles circulaires (5, 10, 12).
