Problems solved by technology

The inconvenience of these solutions is that due to the high operating temperature of conventional bulbs, the mobile sensor needs to be installed at a distance of more than 0.5m, which causes high cost of equipment due to high installation costs.
Another major disadvantage is that the bulb often needs to be replaced due to its short lifetime in successive on-off cycles
Another inconvenience that adds to the cost of installation is the need to install motion sensors at all entrances or on every floor

Embodiment Construction

[0021] figure 1 A block diagram of the method for automatically adjusting illumination intensity according to the present invention is shown in the simplest embodiment. In this alternative, the device with automatic adjustment of light intensity contains an electronic control unit, light source, motion and twilight sensors. The gist of the method is that, after connecting the device to the supply network, set the following parameters in the ECU: the minimum feed voltage value that allows the ECU and the motion and dusk sensors to remain in "standby" mode, then, the sensors and the ECU Synchronization of the unit, and the value of the output signal generated by the motion sensor and the excitation duty cycle of the device, the value of the output signal generated by the twilight sensor, on which the voltage supplied to the light source is gradually increased up to a maximum value and the light source emits light at full 100% power, The light emission time, after which the volt...

Abstract

Provided are a method of lighting intensity automatic adjustment and a corresponding device, in which the light emitted by a light unit is adjusted according to the input signal from a passive infrared motion sensor and / or a dusk sensor. In one embodiment, starting from a stand-by condition in which the lamp unit is switched-off, the light from the lamp unit is smoothly brightened up to 100% of its maximum power in case of detection of a motion from the motion detector and in case that also a dusk condition is detected by the dusk sensor.

Description

technical field [0001] The invention relates to a method for the automatic regulation of lighting intensity and to devices with automatic lighting intensity regulation, in particular for example high-pressure (mercury discharge lamps, sodium discharge lamps, metal halide lamps) or low-pressure (fluorescent lamps) discharge lamps, energy-saving lamps and lamps with LEDs and light bulb device. Such devices are designed to illuminate buildings, offices, basement stairs, corridors, passageways, etc., and may have any form, such as panels, lighting strips, wall lights, pendant lights, recessed lights, etc. Background technique [0002] Solutions for lighting stairs, passages, rooms, basements based on conventional incandescent bulbs or fluorescent lamps are known, by conventional circuit breaker switches and equipped with time-delay switches that switch off the lights after a preset time, whether or not the user wants such illumination. Another disadvantage of such a solution i...
