An aircraft lamp includes a light source unit, a lamp housing that houses the light source unit, and a power supply control unit that has a casing and includes a control circuit structure configured to control light emission of the light source unit. The control circuit structure is housed in the casing. The casing is disposed outside the lamp housing.

Aircraft lamp

A wall lamp () is fixed to both an airframe () of an aircraft and a wall surface sheet () covering the airframe (). The wall lamp () includes a light source (), a light source holder () that is attached to the wall surface sheet () and holds the light source (), and an attachment portion () that is attached to the light source holder () and the airframe (). The attachment portion () is formed of a material having a melting point lower than that of a material forming the light source holder ().

Wall lamp

An aircraft lamp includes: a lamp outer case constituted by a lamp housing having an opening and a cover mounted to the lamp housing in a state where the opening is closed, an internal space being formed in the lamp outer case as an arrangement space; a light source including a light emitting diode and arranged on an arrangement surface inclined with respect to a predetermined surface to be irradiated in the arrangement space; and an inner lens arranged in the arrangement space and including a control lens configured to control an irradiation direction of light emitted from the light source. The control lens is formed in a shape having a longitudinal direction and a width direction, and the longitudinal direction and the width direction of the control lens are rotated in a direction around a light source optical axis with respect to a vertical direction and a left-right direction.

An aircraft lamp includes a housing capable of being attached to a body of an aircraft; a discharge lamp; a reflector which reflects visible light from the discharge lamp; a light transmissive cover which transmits reflected light from the reflector to a front side of the housing; a lamp socket connected electrically to the discharge lamp and an igniter which activates the discharge lamp; and a high-voltage electrical power line that electrically connects the lamp socket with the igniter. The discharge lamp, the reflector, the light transmissive cover, the lamp socket, and the igniter are provided within the housing. A heat insulating air layer is provided between the lamp socket and the igniter. The high-voltage electrical power line is provided so as to pass through the heat insulating air layer.
