A halogen torchiere lamp diffuser apparatus includes a reflective element (21) situated directly under the halogen bulb (12) within the lampshade (10). The reflective element (21) has an elongated projection (25) within a trapezoidal or triangular cross section and with a minimal top surface (31) such that light, and thereby heat, is diffused outward towards the edges of the lampshade (10) and not concentrated immediately above the bulb (12). In addition, the reflective element (21) includes a flat section (22) extending outward from the projection (25) and having curved cutouts (38, 39) therein to allow air to pass the bulb (12) and convect heat away from the bulb (12). The apparatus further includes a glass shield (45) spaced at a critical distance above the bulb (12) and its cylindrical glass cover (16), thereby allowing heat to be convected away from the bulb (12). The apparatus can be adapted as a "retrofit" apparatus that can be installed to an existing halogen torchiere lamp by a consumer. |
