Disclosed is a high-pressure discharge lamp () that reduces the occurrence of cracks even under high mercury vapor pressure. The high-pressure discharge lamp () is provided with a glass arc tube () including a light-emitting part () and a sealing part () connected to the light-emitting part (), the light-emitting part () enclosing a discharge space, and a pair of electrodes (), one end of each of the electrodes () facing one end of the other electrode () in the discharge space, and another end of each electrode () being embedded in the sealing part () and connected to a metal foil (), at least one embedded section of the pair of electrodes () including at least one projection ().

An LED lamp has an envelope that includes a globe and a case, an interior space of the envelope being divided in two by a mount closing an opening of the globe, the lamp containing, in a globe side of the interior space, an LED and, in a case side of the interior space, a circuit unit for causing the LED to emit light. The LED is thermally connected to the mount, and the mount and the case are joined to the globe such that, during light emission, at least as much heat from the LED is propagated from the mount to the globe as from the mount to the case.

A mount member () has a contact surface () touching the bottom surface of an LED module () and protrusions () protruding from the periphery of the contact surface () in the thickness direction of the LED module () and regulating sliding motions thereof. A fixing member () made of a resilient, plate-like member comprises an opposing pair of flat portions () near the contact surface () of the mount member () and flat tabs () projecting from the flat portions () toward the contact surface () touching the upper surface of a substrate (). The flat portions () of the fixing member () are fastened to be lower than the top surface of the substrate () of the LED module (). Thus, elastically deformed areas extending from the fastened parts of the flat portions () through the flat tabs () press the substrate () into the mount member ().
