<p>A lamp head incorporated with an anti-combustion arrangement, which includes an upwardly directed pan and a reflector member disposed internally of the pan. Th e 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 refl ecting surface positioned below the halogen light source. A shielding lens is mounted on the p lanar lip for closely covering the halogen light source wherein a high temperature burning zon e is formed above the concave reflecting surface and around the halogen light source. The a nti-combustion arrangement includes a transparent protective shelter and a supporting means. T he protective shelter has a size adapted to entirely cover the halogen light source, the suppo rting means being disposed on the reflector member for supporting the protective shelter at a pred etermined 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.</p> |
