Embodiment Construction

[0026] figure 1 Shown is a heating device 1 for heating a glass surface 2, such as a cover glass, such as a cover glass for an outdoor camera of a vehicle, or a monitoring device, such as is arranged at a traffic point, such as in a tunnel system, a crossroad Traffic monitoring cameras at the entrance or other suitable optical and / or electronic devices such as headlights or protective glass of other mobile devices.

[0027] exist Figure 4 The outdoor camera shown in detail in , is in particular a conventional image recording device, such as a video camera or a CCD image sensor (CCD=charge-coupled-device (charge-coupled device)). The outdoor camera here has at least one data processing unit and a communication unit. The communication unit is designed as an Ethernet connector. The glass surface 2 is heated directly by means of the heating device 1 and the outdoor camera is designed as a CCD camera, so that low power is sufficient to supply both the outdoor camera and the hea...

Abstract

The invention relates to a heating device (1) for heating a glass surface (2) by means of at least one heating element, which has been applied to the glass surface (2) as a material layer (1.1). Due to such direct heating of the glass surface (2), such as of a protective glass, in that the material layer (1.1) applied in a positive, bonded and non-positive manner, the energy input necessary for heating is low, and the heating is carried out in a uniform manner free of interferences.

Description

technical field [0001] The invention relates to a heating device for heating a glass surface, in particular a cover glass of an outdoor camera, such as a surveillance camera arranged on a vehicle or at an intersection. Furthermore, the heating device is an electronic and / or optical device, in particular an outdoor camera with a protective glass. Background technique [0002] Heating of the protective glass of cameras for outdoor use is necessary to avoid fog, dew and icing. [0003] Typically for cameras used outdoors, the protective glass is heated indirectly. This is achieved, for example, by a power resistor or a wire-wound heating element which is arranged in the region of the cover glass, for example on or around the cover glass. Such indirect heating has a high energy demand. [0004] It is also common practice to apply thin heating wires directly to the cover glass. This often leads to disturbances in the recording of the camera and uneven heating of the protectiv...
