Abstract

Soldering and similar processes can be carried out by use of focused infrared light energy. Where the heat is to be applied along a line an elliptical reflector is often used. The heat source is at the focus of the elliptical cross-section and the work is placed at the other focus.

Infrared Lamp Reflector

Soldering and similar processes can be carried out by use of focused infrared light energy. Where the heat is to be applied along a line an elliptical reflector is often used. The heat source is at the focus of the elliptical cross- section and the work is placed at the other focus.

Where the shape of work 10 prevents the use of a full elliptical reflector, a similar result can be achieved by employing a reflector which has region 12 of elliptical cross-sectional shape and region 14 of circular cross-sectional shape. Heat source 16 is placed at a line which constitutes one focus of region 12 as well as the axis region 14.

Certain light rays such as 18 are reflected directly from region 12 along path
20. Other light rays 22 are reflected by region 14, back Past source 16 along line 24 and then are reflected by region 12 along path 26 as if they had originated directly from source 16. The shape of region 14 permits the reflector body to be cut back at 28 so as to clear portion 30 of the workpiece or workpiece holder while enabling the part to be heated to be located at focus 32 of the infrared energy pattern.
