Embodiment Construction

[0020] The flashlight shown in the drawings has a cylindrical shape, which comprises: a screw end cap 10 detachably fixed on the end side, which is composed of a fixing sleeve 11 and a knob 12; An open end 13 is formed as a light exit surface. At least one battery or a battery pack or a battery box 15 is arranged in the flashlight housing 14, and the battery box accommodates a plurality of batteries connected in series. In addition, the torch has a contact plate 16 with at least one light-emitting diode (LED) 17 . When a single light-emitting diode 17 is used, different colors and / or different brightnesses can be emitted depending on the voltage applied to said light-emitting diode 17 .

[0021] The flashlight also has an additional optics 18, which is configured as a reflector lens, wherein the light rays emitted in the center are projected onto the inner converging lens part and are focused there into parallel light, while in the The laterally emitted light rays then fall ...

Abstract

The invention relates to a torch having a rotary switch which serves to switch different degrees of brightness and / or colors of light. Said switch comprises a battery cartridge (15) that is rotatably housed in a torch case (14) and has resiliently received electrical contacts (20, 21) on its face, said contacts being connected to electrical contact surfaces (5) or electrical contact zones (1, 2, 3, 4) of a contact plate (16). The aim of the invention is to devise a torch having different switching states that has a compact design and that can be switched in a simple and reliable manner. For this purpose, the battery cartridge is captively retained in the torch case by means of a locating sleeve (11) and the battery cartridge is rotated by means of a rotary knob (21) that axially extends through the locating sleeve.

Description

technical field [0001] The invention relates to a flashlight which is provided with a rotary switch for switching between different brightness levels and / or light colors, said rotary switch having a battery pack rotatably arranged in the flashlight housing, the battery pack having a End-side, elastically mounted electrical contacts, which are each connected to an electrical contact surface or electrical contact area of ​​a contact plate. Background technique [0002] Over the past few years, traditional incandescent bulb flashlights have been increasingly supplanted by light-emitting diode (LED) flashlights. The advantages of light-emitting diodes are, inter alia, their lower power consumption compared to incandescent bulbs, their insensitivity to shocks and impacts, and their significantly longer service life. The reason for this is, inter alia, that a greater proportion of the supplied energy is - as is the case with incandescent light bulbs - converted directly for the p...
