ABSTRACT:
A lamp head incorporated with an anti-combustion arrangement, which includes an upwardly directed pan and a reflector member disposed internally of the pan. The reflector member has a planar lip for supporting a reflecting disc and a holding means for electrically receiving a halogen light source. The reflecting disc has an inner concave reflecting surface positioned below the halogen light source. A shielding lens is mounted on the planar lip for closely covering the halogen light source, wherein a high temperature burning zone is formed above the concave reflecting surface and around the halogen light source. The anti-combustion arrangement includes a transparent protective shelter and a supporting means. The protective shelter has a size adapted to entirely cover the halogen light source, the supporting means being disposed on the reflector member for supporting the protective shelter at a predetermined height from the planar lip and right above the halogen light source to cover the high temperature burning zone and to define an air ventilation clearance between the protective shelter and the halogen light source.
