Abstract
PURPOSE: To prevent the local cooling of the tube face of a fluorescent lamp directly above and remove the sticking of mercury grains by providing turbulence generating lugs on part of the side face of a louver arranged directly below the fluorescent lamp. CONSTITUTION: When a louver 4 is fitted to a reflector 2, nearly triangular conical turbulence generating lugs 6 are integrally protruded on both sides of the upper end of the louver 4 located directly below a fluorescent lamp 3 arranged in parallel with the reflector 2. The air rising along the side faces of the louver 4 is made turbulence by the lugs 6 at the upper end of the louver 4, and the air flow to the tube face directly above the fluorescent lamp 3 is dispersed, thereby local cooling is prevented, and no mercury grain is stuck.
