An aim is to provide a light source device that can be assembled more easily than conventional light source devices. A light source devicecomprises a light emitting module, a mount, a lighting unit, and a case, wherein the lighting unithas a pair of pin terminalsand, each of the mountand a substrateof the light emitting modulehas a pair of through-holesand, and a pair of feed terminalsandare disposed at positions of the substratecorresponding to the through-holesand, the pair of pin terminalsandbeing electrically connected to the pair of feed terminalsandby penetrating through the through-holesandof the mountand the substrate

Light source device

An LED lampthat is a light source device includes a light emitting module, a bodythat is a first thermal dissipation member onto which the light emitting moduleis attached, a circuit unitfor lighting the light emitting module, and a casethat is a second thermal dissipation member that has the circuit unithoused therein, and a thermal insulation memberis inserted between the bodyand the case

Light source device with thermal dissipating members

Light source apparatus whose front cover can be removed easily and which can be attached to socket easily even if the base is screw-in type. The light source apparatus includes: cylindrical bodyhaving opening; light-emitting modulehoused in body; and front coverattached to opening-side end of body. Ring-like flangeis provided at opening-side endof body. A plurality of clawsare provided at circumferential edgeof front cover. Front coveris fitted to opening-side endof bodysuch that flangeis covered by circumferential edgeof front cover. Flangeis provided with at least one stopper facewhich, when it is in contact with at least one claw, restricts front coverfrom rotating around cylindrical axis J of body

Light source apparatus

Provided is a light-bulb type LED lampincluding a plurality of LEDs-, a base, a lighting circuit unit that converts commercial power provided through the baseinto power for lighting the LEDs-, and a heat radiation memberthat includes a bowl-shaped portion. Two stagesand, extending inwards from an inner circumferential surfaceof the bowl-shaped portion, are provided in a direction of a central axis X of the bowl-shaped portion. The LEDs-are mounted on the stagesandin a circumferential direction around the central axis X.

Light-bulb type LED lamp and illumination apparatus

A reflector LED lamp comprises: a reflectorhaving a spheroidal reflecting surface with an opening provided therein; a plurality of LEDs, andarranged in the reflector, on a plane perpendicular to an optical axis X of the reflector; and a lighting circuit operable to light the plurality of LEDs, wherein the plurality of LEDs are divided into at least a first group (LED) and a second group (LED, and), the first group arranged at a first distance from the optical axis X, the second group arranged at a second distance from the optical axis X, the second distance being longer than the first distance, and while the plurality of LEDs are lit by the lighting circuit, luminous flux per LED is larger in the first group than in the second group.
