Document Type and Number:
Japanese Patent JP5621140
Kind Code:
B2
Abstract:
An LED lamp includes a heat dissipator, a cap, a module substrate fixed to an end of the heat dissipator and on which an LED chip is mounted, a light diffusing member mounted on an end surface of the heat dissipater so as to be located opposite the LED chip, a lighting circuit incorporated in the heat dissipator, and a glass block having an open end and formed with a recess. The light diffusing member is accommodated in the recess of the block through the open end of the glass block, and the heat dissipator is secured to the block so that the heat dissipator and the cap are exposed outside the block. When the block is placed on a placement surface, the LED lamp stands by itself by weight of the block in such a manner that the cap is prevented from contacting the placement surface.
