Abstract

PURPOSE:To improve heat radiation while providing efficiency in passing light reflected on the housing walls through an open end of a lighting equipment main body by means of reflecting cut members so lifted up from the wall of the lighting equipment body incorporating a lamp as to reflect the light from the lamp downward through the open end thereof. CONSTITUTION:A cubic lighting equipment body 1 has an open lower end with a flange section 2. A socket retaining hole 3 is formed on a ceiling plate 1a which faces the open end. In addition, some parts of the plate 1a are cut and lifted up to form heat radiant holes 4. Part of walls 1b of the body 1 is cut to form members 5. The body 1 is inserted into a hole A of the ceiling from below thereof and embedded in the ceiling. The light from a lamp 8 passing through below the open end of the body 1 while irradiates directly therebelow does therebelow again being reflected on the members 5. The heat from the lamp 8 escapes outside the body 1 through the clearance between the members 5 and the walls b and the holes 4.
