Abstract
The invention relates to a torch having a housing in which at least one LED secured to a carrier element, and a lens system, are arranged and can be displaced relative to one another in order to focus the cone of light that is emitted. According to the invention, a seal consisting of a membrane (14) closes the space (23) between the LED (11) and the lens system (13) in a watertight and dust-proof manner.
Claims18
A torch with a housing, in which at least one LED attached to a support element and an optical attachment are arranged, which are displaceable relative to one another for focusing the light cone radiated, characterized in that
- a seal comprising a membrane closes the space between the LED and the optical attachment in a dust-tight and waterproof manner,
- wherein the seal has at an upper edge a collar or a rib, wherein the collar or the rib is clamped between the optical attachment and the housing in a groove incorporated on an inner wall of the housing and at least one of:
- (i) a lower edge of the seal is connected to an annular body, the surface of which facing an inside of the seal is a groove, which together with a hook-shaped nose of the support element forms a positive connection, or (ii) the seal has an inner jacket in the lower region with an annular rib, the inner jacket engaging a groove of the support element.
A torch with a housing, in which at least one LED attached to a support element and an optical attachment are arranged, which are displaceable relative to one another for focusing the light cone radiated, characterized in that a seal comprising a membrane closes the space between the LED and the optical attachment in a dust-tight and waterproof manner, wherein the support element comprises:
- a circuit board supporting the LED with voltage connections,
- two or more clamping elements for fixing the circuit board on pins that are used for the voltage supply,
- a base plate fixed in a non-rotating manner in the lamp housing from which the two clamping elements project,
- a holder with holes to lead the pins through and
- a front cover element, which comprises a front opening for the LED and snap-in hooks, which protrude to the rear and engage in corresponding recesses of the holder, forming a snap connection.
