BALLAST INTERNAL TYPE LAMP THAT HEIGHTEN LIGHT DISTRIBUTION EFFICIENCY

摘要

A ballast-embedded type lamp is provided to improve illuminance of the lamp by refracting the light emitted from a rear surface of a U-shaped lamp into a lower part through a reflecting member of a cone shape. A ballast-embedded lamp includes a body(11) and a reflecting member(20). The ballast is arranged within the body. A plurality of heat exhaust holes(12,13) are formed at the center of one surface and side surface of the body. A plurality of U-shaped lamps(L) are arranged in the form of a barrel. A plurality of bonding holes are formed at radial positions with respect to the position where the heat exhaust holes are formed. The reflecting member is installed at the boding holes. The reflecting member has a cone-shaped body(21). External surface of the body of the reflecting member are coated with reflecting material. Therefore, the reflecting member reflects the light emitted from the U-shaped lamp into a lower part. The reflecting member has a leg(22) and a hook(23). The leg forms a heat exhaust pass(44). The hook is formed at an end of the leg.
