PURPOSE:To radiate heat in a lightening device body to the outside of heat insulating material to prevent a drop of the device efficiency for ensuring heat radiation by installing a heat radiating cylinder through which heat insulating material is provided in a projecting condition at the back of the body. CONSTITUTION:This lighting device 10 is installed covered with heat insulating material 21, and made up such that a heat radiating cylinder 22 having a length which can penetrate the heat insulating material 21 is installed projected to a device body 15 in such a condition that the heat radiating cylinder 22 is opened within the body 15. The heat of a stabilizer 12 is, therefore, radiated to the outside of the heat insulating material 21 passing through the heat radiating cylinder 22. Further, the heat of a lamp 16 is also radiated from the heat radiating cylinder 22 through the air vent 20 of a reflecting plate 13. Thereby, the inside of the equipment body 15 is not filled with heat and it is possible to hold down the temperature of the stabilizer and various types of electric parts such as a socket, etc. to a minimum and also prevent a drop of the equipment efficiency, e.g., a short life, etc. and also the lamp flux can be increased as the temperature of the lamp 16 can be held down to a minimum. |
