Heat sink for led bulb

Led電球用ヒートシンク

Abstract

【課題】軽量化が図れ、複雑な形状の金型が不要なことは勿論のこと、LED発光源からの放熱を効率的に行うことができ、LED電球の長寿命化が図れ、また、部品点数が増加することもなく、従来と比較して製造コストも低減することができるLED電球用ヒートシンクを提供することを課題とする。 【解決手段】金属製板材から形成されたLED電球用ヒートシンクAであって、表面側にLED発光源4が載置固定された円盤状部2と、円盤状部2と一体になって形成された筒状の放熱部1より成り、筒状の放熱部1の先端側には口径が狭められた筒状の口金取付部3が形成されている。 【選択図】図1
PROBLEM TO BE SOLVED: To provide a heat sink for LED bulb in which weight reduction is attained, molding of a complicated shape is not required, heat radiation from an LED light emission source can be made efficiently, while long life of the LED bulb can be attained and manufacturing cost can be reduced compared with a conventional one without increasing the number of components.SOLUTION: The heat sink for LED bulb A is formed of a metal plate material, and is composed of a disk part 2 of which on the front surface side an LED light-emitting source 4 is mounted and fixed and a cylindrical heat radiation part 1 which is formed integrally of the disk part 2. A cylindrical base installation part 3 of which the diameter is narrowed is formed at the tip side of the cylindrical heat radiation part 1.
