Description

本発明に係るＬＥＤランプは、ＬＥＤ素子が実装されたＬＥＤ基板と、前記ＬＥＤ基板を載置して放熱する載置部材と、点灯回路基板を収納する筒状の絶縁筐体と、該絶縁筐体を収納する筒状の放熱部材と、前記ＬＥＤ基板を覆うように装着された透光性カバーとを備えたＬＥＤランプにおいて、前記載置部材は前記放熱部材の一端開口側に固定され、前記透光性カバーはドーム状に形成されて開口端部に当該開口端部からみてドーム状の頂点が存する方向とは略反対方向に延出する延出部を有し、当該延出部に係止部が設けられ、前記載置部材は径方向外側に突出する係止用突出部を有し、前記係止用突出部に前記係止部が係止される。 An LED lamp according to the present invention includes an LED substrate on which an LED element is mounted, a mounting member that mounts the LED substrate to dissipate heat, a cylindrical insulating housing that houses a lighting circuit substrate, and the insulating housing. a cylindrical heat radiation member for accommodating the body, in the LED lamp and a loaded translucent cover so as to cover the LED substrate, before placing member is fixed to one open end of the heat dissipation member, the The translucent cover is formed in a dome shape, and has an extending portion extending in a direction substantially opposite to the direction in which the apex of the dome exists when viewed from the opening end portion. A stopper is provided, and the mounting member has a locking protrusion protruding outward in the radial direction, and the locking part is locked to the locking protrusion .

また、前記透光性カバーは、前記載置部材に対して反時計方向に回転されることにより、前記透光性カバーの係止部が前記載置部材の係止用突出部に係止されてもよい。 In addition , the translucent cover is rotated counterclockwise with respect to the mounting member, so that the locking portion of the translucent cover is locked to the locking protrusion of the mounting member. May be .

本発明に係るＬＥＤランプによれば、透光性カバーは載置部材に機械的に係止されているため、透光性カバーの落下を防止できる。 According to the LED lamp according to the present invention, since the light-transmitting cover is sealed mechanically engaged to the mounting member and cut the falling of the translucent cover prevention.
