Patent ID: 8710722

Claim:
An LED lamp comprising: a heat dissipator; a cap fixed to an end of the heat dissipator; a module substrate which is fixed to an end of the heat dissipator and on which an LED chip is mounted, said end to which the module substrate is fixed being located opposite the cap; a light diffusing member which is mounted on an end surface of the heat dissipator so as to be located opposite the LED chip, the light diffusing member peripherally diffusing light emitted by the LED chip; a lighting circuit which is incorporated in the heat dissipator to supply electric power to the LED chip, the lighting circuit being electrically connected to each one of the cap and the module substrate; and a glass block having an open end and formed with a recess, wherein the light diffusing member is accommodated in the recess of the glass 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; and when the block is placed on a placement surface for the LED lamp, the LED lamp stands by itself under weight of the block in such a manner that the cap is prevented from contacting the placement surface.
