<p>The present invention relates to a heat radiator assembly comprising at least on e heat radiator unit which comprises in combination a base and a primary reflector mounted on the bas e, the primary reflector having an elongated body with side walls (with a parabolic configurati on in cross-section) upstanding outwardly from the base and end walls. A lamp is accommodated within the primary reflector by means of an elongated gap formed between lateral edges of t he side walls of the primary reflector adjacent to the base. A secondary reflector having a gener ally elongated configuration is mounted on the base; it has an inner and an outer surface. The secondary reflector '8 inner surface faces the elongated gap of the primary reflector and the outer surface faces the base; the secondary reflector is adapted to reflect all lost radiation emitted f rom the lamp through the gap towards the base, thus facilitating prevention of overheating of the bas e and increasing efficiency of the heat radiator assembly. The secondary reflector has a concave configuration in cross-section, and the primary and secondary reflectors may be made of tempered aluminum embossed with a pattern facilitating heat radiation efficiency and to strengthen structural integrity of the heat radiator unit.</p> |
