Beschreibung
Zusammenfassung:	A heat radiating device for use in an illuminating apparatus comprising a heat radiating member secured to a wall of a body of said apparatus and formed with end openings at the opposite ends thereof. Air vent means adapted to establish air communication between the inside of said body and the atmosphere pass through the inside of the heat radiating member. As a result the temperature rise of the apparatus which is caused by a lamp bulb therein can be kept below a certain value and the life of the bulb can be increased. Additionally, stainless steel which has not been used in the past in the construction of the apparatus because of its relatively low heat conductivity may now be used so that the painting process applied to said body may be eliminated and the durability of said body may be increased.
