Embodiment Construction

[0032] figure 1 A reflector 1 for a headlight 12 of a two-wheeled vehicle, in particular a bicycle, is schematically shown. The headlight also includes a holding element 16 . The holding element is integrally formed on the reflector 1 . The retaining element 16 has a recess 2 (see especially image 3 ). According to the invention, a printed circuit board 3 with light-emitting diodes 4 and a heat sink 5 are inserted into the recess 2 . The recess 2 forms a guide for the printed circuit board 3 and, in the exemplary embodiment, also for the heat sink 5 .

[0033] Both the printed circuit board 3 and, in the exemplary embodiment, the heat sink 5 are non-positively and / or positively connected to the recess 2 . In the present embodiment, the circuit board 3 is clamped to the corresponding recess 2 . As a result, the circuit board 3 is fixed and the light-emitting diodes 4 are held at the focal point of the reflector 1 , wherein the light-emitting diodes 4 are arranged outside...

Abstract

The present invention relates to a headlight (12) for bicycle, comprising a reflector (1) that reflects light emitted from at least an LED (4), and at least holding element (16) that supports at least a circuit board (3) that is connected with at least a said LED (4). The holding element is formed outside the reflector and has a recess (2), with which the circuit board is connected in a shape locking and/or force locking manner. At least one of the recess (2) the circuit board (3), the reflector (1) and the LED (4) is designed to form an angle between 90 DEG to 130 DEG between the first main beam direction (7) of the LED (4) and the second main beam direction (8) of the reflector (1). The headlight has simple installation, good fixation of LED in the reflector. Lightful headlight is formed and reflection area covering at least 40% of the opening area of the reflector can be arranged.

Description

technical field [0001] The subject of the invention is a headlamp for two-wheeled vehicles, in particular bicycles. Background technique [0002] Headlamps with light emitting diodes for two-wheeled vehicles are known. Such headlights are usually mounted by fastening a circuit board with light-emitting diodes on a holding element. The positioning of the light-emitting diodes thus changes, which leads to poor lighting results. In addition, screw manufacturing and positioning of the circuit board will increase the cost. Contents of the invention [0003] It is therefore the object of the invention to at least alleviate the disadvantages known from the prior art. In particular, a headlight is provided which is simple to install and at the same time enables the most precise positioning of the light-emitting diodes. [0004] This object is achieved by a headlight having the features of the independent claim. The dependent claims relate to advantageous developments. [000...
