Abstract

The invention relates to a method for operating a clocked electronic power converter having an output power range for operating a connectable load, the output power range resulting from a permissible output voltage range and a permissible output current range, and the power converter having a switch, an inductance and an on-off keying device. The method is characterised by the following steps: - in a first mode of operation, which ranges from the maximum output current of the power converter of 100% to a reduced output current, setting the on-off keying device to a burst duty cycle of 100%, and adjusting the converter clock frequency or the switch-on time period of the switch, in order to increase or to reduce the output current of the power converter for the load, - in a second mode of operation, which ranges from the reduced output current to the minimum output current, maintaining the converter clock frequency or a minimum switch-on time period of the switch and setting the burst duty cycle, in order to change the working point and thereby to further reduce the output current of the clocked converter for the load. An on-off keying burst frequency is reduced from a burst duty cycle lying in the range from 40% to 20%, with a decreasing burst duty cycle, in order to keep a ripple of the output current in a required range, and the burst frequency at the burst duty cycle lying in the range from 40% to 20%, is higher by the factor 2 to 40, preferably by the factor 3 to 15, than the burst frequency at the minimum duty cycle.

Abstract

The invention relates to a device (10) for sterilising a fluid flowing therethrough by means of UV radiation (UV reactor), said device comprising a container (20) having an inlet (22) for receiving the fluid and having an outlet (24) for discharging the fluid from the container (20), a variable or adjustable irradiation zone (12) for irradiating the fluid with UV radiation being provided within said container (20). The irradiation zone (12) is designed as a gap which extends between two oppositely arranged reactor walls (14, 26) and though which the fluid flows. The mutual distance (D) between the reactor walls (14, 26), and thus also the gap size (D) of the gap, can be changed by designing at least one reactor wall (14) to be movable. For example, the movable reactor wall (14) is a wall of a displaceable body (9) that is located inside the container (20) or projects into the container. By adjusting the distance between the reactor walls (14, 26) in the region of the irradiation zone (12) that is in the form of a gap, and thus the layer thickness (D) of the fluid flowing through the gap, the efficiency of the operation of the UV reactor (10) is optimised with different scattering and absorption properties of the fluid. Optionally, the penetration depth of the radiation is detected using a sensor (7) and the gap size (D) is adjusted on the basis of the sensor signal.

Abstract

An image displaying device includes a micro-LED-array having several LEDs, a controller electrically connected to the micro-LED-array for driving the LEDs such that they emit light, and a lens-array having several lenses. Each lens is assigned to one of the LEDs. Each lens is arranged in the light path of the light emitted by the corresponding LED such that the light emitted by the LEDs passes through the corresponding lens and is projected onto a screen. The lens-array is configured such that, when seen from the screen, a virtual image of the micro-LED-array is formed behind the micro-LED-array. The lens-array is a meta-lens-array and the lenses are meta-lenses.

Abstract

A luminophore mixture for use in a conversion layer applied to a semiconductor light source comprises a first luminophore designed to emit light of a first unsaturated colour when it is irradiated with light by the semiconductor light source and is the sole luminophore provided in the conversion layer, where the first unsaturated colour is associated with a first position in a CIE standard chromaticity diagram which is adjacent to and above a position of a selected target colour of the luminophore composition in the CIE standard chromaticity diagram, and it comprises a second luminophore designed to emit light of a second unsaturated colour when it is irradiated with light by the semiconductor light source and is the sole luminophore provided in the conversion layer, where the second unsaturated colour is associated with a second position in a CIE standard chromaticity diagram which is adjacent to and below the position of the selected target colour of the luminophore composition in the CIE standard chromaticity diagram. The position of the selected target colour of the luminophore composition in the CIE standard chromaticity diagram here is within an area defined by vertex positions R = (cx; cy) given by R1 = (0.645; 0.335), R2 = (0.665; 0.335), R3 = (0.735; 0.265), and R4 = (0.721; 0.259).

Abstract

A table-top unit (1, 2, 3) for generating a substantially microbe-inactivated room zone (5) comprises a housing (10) with an interior (14), which has a longitudinal axis, a blower device (60) which is designed to receive air from outside and convey it into the interior (14), a radiation source (50) which is designed to emit light in the UV-C spectral range into the interior (14), in order to inactivate or kill off microbes in the received air (121), and an air outlet device (70) through which the sterilized air (122) can flow from the interior (14) into a room surrounding the housing (10). The air outlet device (70) is designed to produce a preferably laminar flow in the outflowing air (123), which supports the formation of the substantially microbe-inactivated room zone (5) within the surrounding room. The substantially microbe-inactivated room zone (5) generated in this way is closed off and completely envelops the housing (10) when the latter is viewed in a plane perpendicular to the longitudinal axis of the housing (10).

Abstract

An electronic load (15, 16, 17, 18) for installation in the power supply of a vehicle lamp (8) comprises a first connection node (N1), which is connected to two first connection sections (12a, 12b) which are designed to be connected between corresponding connection sections of a first line (6) which carries a voltage potential, and a second connection node (N4) which is connected to two second connection sections (11a, 11b) which are designed to be connected between corresponding connection sections of a second line (7) which carries a reference potential. The supply voltage supplied via the lines (6, 7) of the vehicle lamp (8) corresponds to the difference between voltage potential and reference potential. A current sink circuit (50, 51, 52, 53) switched between the connection nodes and connected to same is designed to effect a substantially constant current flow independently of a supply voltage which changes over time from at least one of the first connection sections (12a, 12b) to at least one of the second connection sections (11a, 11b). The electronic load is configured to be connectable to the first and the second line (6, 7) in order to provide the current flow in parallel to the vehicle lamp (8).

A combined error may be determined during the training, which error results from the errors of the determining of the class identification vector, determining of the at least one identification vector, the determining of the specific bounding box regression, and the determining of the inter-frame regression.
