Abstract
The protection lens is used for protecting lamps on machine tools against splashing liquid and chips. The lens also ensures that light is concentrated on the workpiece. The use of the lens is also justified if no dirt is present which could impair the light, because the light is concentrated better on the actual workpiece. The protection glass (2) with lens section (3) is fitted into the reflector housing (1). An O ring (4) is used for sealing. This seals the lens housing and enclosed reflector housing (5). A spring ring (6) is used for holding the lens in the housing.
Description
An Werkzeugmaschinen sind Arbeitsleuchten dem Spritzwasser und Späne anfall ausgesetzt. Durch ein Vorsatzglas kann der Leuchtkörper und der reflektierende Innenteil des Reflektors geschützt werden.
Gegenstand vorliegender Erfindung ist ein Schutzglas für eine Arbeitsleuchte, welches eine optische Linse aufweist, um das Licht im erforderlichen Abstand auf das Arbeitsstück zu konzentrieren.
Wenn an einer Arbeitsleuchte aus erwähntem Grunde ein Schutzglas nötig ist, wird mit einem Schutzglas gemäss vorliegender Erfindung bedeutet mehr Licht auf das Arbeitsstück gelenkt, damit ist der Wert der Arbeitsleuchte erhöht.
Eine Arbeitsleuchte mit Schutzglas gemäss vorstehender Erfindung kann sich auch dann rechtfertigen, wenn nvar kein Schutzglas nötig wäre, aber durch die optische Linse mehr Licht auf das Arbeitsstück erwünscht ist.
Ein Ausführungsbeispiel zeigt Fig. 1.
Im Reflektoraussenteil 1 ist ein Schutzglas 2 mit einer optischen Linse 3 eingebaut. Als Dichtung dient ein O-Ring 4, welcher gegen Reflektor-Aussenteil und Reflektor-Innenteil 5 abdichtet, als Halterung im Reflektor ein Sprengring 6.
PATENTANSPRUCH
Schutzglas für eine elektrische Arbeitsleuchte, dadurch gekennzeichnet, dass es eine optische Linse aufweist.
UNTERANSPRÜCHE
1. Schutzglas nach Patentanspruch, dadurch gekennzeichnet, dass es einstückig ausgebildet ist.
2. Schutzglas nach Patentanspruch, dadurch gekennzeichnet, dass die optische Linse als ein Stück ausgebildet ist und am Schutzkörper befestigt ist.
3. Schutzglas nach Patentanspruch, dadurch gekennzeichnet, dass das Schutzglas aussen konvex ist.
4. Schutzglas nach Patentanspruch, dadurch gekennzeichnet, dass das Schutzglas am Rande der Linse plan-parallel ist.
5. Schutzglas nach Patentanspruch, dadurch gekennzeichnet, dass der Schutzkörper und/oder die optische Linse aus lichtdurchlässigem Kunststoff besteht.
**WARNUNG** Ende DESC Feld konnte Anfang CLMS uberlappen**.
Work lights on machine tools are exposed to splashing water and chips. The luminous element and the reflective inner part of the reflector can be protected by an additional glass.
The present invention relates to a protective glass for a work lamp which has an optical lens to concentrate the light on the work piece at the required distance.
If a protective glass is required on a work lamp for the reason mentioned, a protective glass according to the present invention means more light is directed onto the work piece, so that the value of the work lamp is increased.
A work lamp with protective glass according to the above invention can also be justified if no protective glass is necessary, but more light is desired on the work piece through the optical lens.
An exemplary embodiment is shown in FIG. 1.
A protective glass 2 with an optical lens 3 is built into the reflector outer part 1. An O-ring 4, which seals against the reflector outer part and reflector inner part 5, serves as a seal, and a snap ring 6 serves as a holder in the reflector.
PATENT CLAIM
Protective glass for an electrical work lamp, characterized in that it has an optical lens.
SUBCLAIMS
1. Protective glass according to claim, characterized in that it is formed in one piece.
2. Protective glass according to claim, characterized in that the optical lens is designed as one piece and is attached to the protective body.
3. Protective glass according to claim, characterized in that the protective glass is convex on the outside.
4. Protective glass according to claim, characterized in that the protective glass is plane-parallel at the edge of the lens.
5. Protective glass according to patent claim, characterized in that the protective body and / or the optical lens consists of translucent plastic.
