Abstract

A durable lamp, comprising: a hollow main body with a front end, having an inner cavity, which towards the front end forms an open accommodating space; a light bulb, mounted in the accommodating space; a light filter, mounted in front of the light bulb; and a fan, mounted in the cavity, for directing air from outside the main body through the cavity along a ventilation path that passes the light bulb, so as to cool the light bulb during operation.

Claims

1. A durable lamp, comprising:

a hollow main body with a longitudinal axis and a front end, having an inner cavity, which towards said front end forms an accommodating space, which is open on said front end of said main body;

a light bulb, located in said accommodating space;

a fan, mounted in said cavity, for directing air from outside said main body through said cavity along a ventilation path that passes said light bulb, so as to cool said light bulb during operations;

a light filter, mounted in front of said light bulb

a first spring between said light filter and said light bulb; and

a second spring between said light bulb and said main body on a location behind said light bulb;

wherein said light bulb is movable within said accommodating space along said longitudinal axis.

7. The durable lamp according to claim 1 wherein the light bulb comprises an ultraviolet light bulb.

2. A durable lamp, comprising:

a hollow main body with an inner cavity having a longitudinal axis and a front end portion forming an accommodating space which is open on a front end of said main body;

a light bulb, movably mounted in said accommodating space so as to be movable along the longitudinal axis; and

a fan, mounted in said cavity, for directing air from outside said main body through said inner cavity along a ventilation path that passes said light bulb, so as to cool said light bulb during operation.

3. the durable lamp according to claim 2, further comprising a light filter, mounted in front of said light bulb.

4. the durable lamp according to claim 3 further comprising a first spring interposed between said light filter and said light bulb.
