Embodiment Construction

[0028] figure 1 The pico projector P according to the first embodiment of the present invention is schematically shown. in figure 1 Here, the reference sign 1 denotes a micro flat mirror, which is arranged on an attenuating element 9, 52 embedded in an electrical carrier 4. In addition, some electrical components 3 are provided on the electrical carrier 4, such as driving devices, passive components, video decoders, and so on. An electrical connection terminal 5 is also provided on the electrical carrier 4 for providing electrical energy for the micro projector. The electric carrier 4 is also provided with a light source 2 in the form of a laser 2 and optical components 8 in the form of a lens and a flat mirror. The laser 2 emits an extended light beam 6 that is substantially parallel to the electrical carrier 4. The light beam 6 passes through the optical component 8 and hits the micro flat mirror 1, which deflects the light beam 6 into an output light beam 7 for projecting ...

Abstract

A microprojector is described, in which the microprojector includes a light source, at least one optical imaging arrangement for creating an image with the aid of the light source, at least one electrical arrangement for activating the light source, and a damping element for damping mechanical shocks of the microprojector. Also described is a method for manufacturing a microprojector as well as a corresponding utilization.

Description

Technical field [0001] The invention relates to a micro projector (Mikroprojektor) and a method for manufacturing the micro projector. Background technique [0002] Micro projectors are mainly used in the consumer electronics field, such as in mobile phones or notebook computers. They are used for projecting images or for displaying movies when there is no fixed projector available and nevertheless should be used for presentations or presentations for multiple people, for example with slides or charts. [0003] A micro projector usually includes a light source, an image optical system, various electronic components and carrier components. These are generally arranged together in the housing, or in the housing of the notebook computer or mobile phone, or in a separate housing. [0004] US 6,480,634B1 discloses a micro-projector, which includes a laser source, and the laser light of the laser source is transmitted to the image optical system via an optical fiber. The image optical s...
