Title: Lighting equipment for a sewing machine - has halogen lamp focused to fibre optic cables
Inventor: ROESCH JOACHIM
IPC: F21V8/00
Filed: 1989-10-27
Abstract: Lighting equipment with a lamp and a reflector in a housing to illuminate the working point on an industrial sewing machine, has the reflector to focus the light on the end of one or more fibre optic cables. The equipment (1) consists of a housing (2) with rib structure to conduct heat away from the reflector (4) which is ellipsoid, to focus all rays (L1) from the lamp (13) to the focal point (16). This is at the end of a conical chamber in the housing, with a central division to hold an infra-red screen (28), so that only cool light enters the conical chamber. The focal point from the light source is adjacent to the ends of three fibre optic cables (21), set into the end piece (18) by set screws (27). Adjustable screws (17) in the end piece are set to obtain the max. light transfer from the focal point (16) into the ends of the cable (25). Similarly, the halogen light tube (13) is held in the sockets (12) in a holder (11) with adjustment screws (10) which enable the lamp to be positioned to obtain the correct reflection to the focal point. ADVANTAGE - The light source causes less hindrance at the work point. The light can be concentrated at various points. Any heat produced is remote from the work point. Lenses are eliminated.
