    Abstract: A light source comprises at least one light-emitting component, in particular a component emitting ultraviolet light and/or a semiconductor component, and a line system, through which a cooling fluid can flow in a flow direction, for controlling the temperature of the at least one light-emitting component, and also a first and a second cooling-fluid pressure sensor, which are arranged one after the other in the line system in the flow direction, and an electronics unit which is connected to the first and second cooling-fluid pressure sensors and configured to determine at least one diagnostic, control and/or regulating value on the basis of pressures captured by the first cooling-fluid pressure sensor and by the second cooling-fluid pressure sensor.

    Abstract: A high-power light system includes a lamp for producing light within a designated wavelength range, a chiller for maintaining the lamp below a defined temperature threshold, and a control module for regulating operation of both the lamp and the chiller. The lamp includes a plurality of light emitting diodes (LEDs) arranged into independently-operable modules. In use, the control module selectively overdrives the LEDs to yield high-power light within the designated wavelength range. To prevent overheating within the lamp, the control module restricts the lamp to a pulse-based operational cycle, whereby each period of LED activation is of limited duration and is immediately followed by a period of deactivation at least three times as long in duration as the period of activation. Additionally, one or more temperature sensors are disposed within the lamp and enable the control module to temporarily suspend LED activation when measured temperature levels exceed the defined threshold.

    Abstract: A lamp includes a power supply circuit, a light source, a control unit, a first temperature detection circuit, and a second temperature detection circuit. The power supply circuit is provided on a first substrate and configured to generate a predetermined voltage based on a power supply voltage. The light source, which is provided on a second substrate, includes a plurality of light-emitting elements and an adjustment unit configured to adjust a drive current flowing through each of the plurality of light-emitting elements, and uses the predetermined voltage as a power supply. The control unit is provided on a third substrate and configured to control the adjustment unit. The first temperature detection circuit is provided on the first substrate and configured to detect a temperature. The second temperature detection circuit is provided on the second substrate and configured to detect a temperature. The control unit is configured to control the adjustment unit based on a detection result having a higher temperature of detection results of the first and second temperature detection circuits and a signal indicating a turn-on condition of the plurality of light-emitting elements.

    Abstract: A vehicle lighting device includes a socket; a substrate; and one first and four second light emitting elements. A square luminance distribution region is defined on light irradiation sides of first and second light emitting elements. A center of distribution region overlaps central axis of device. Distribution region is equally divided into four square first regions whose corners overlap center of distribution region. Each of first regions is equally divided into nine square second regions. A length of one side of second region is 0.8 mm. Luminance of distribution region is 90% or more of a total luminance of light emitted from device. In twenty second regions arranged along sides of distribution region, luminance of one second region is 2% or less of total luminance. In sixteen second regions provided inside twenty second regions, luminance of one second region is 3% or more and 10% or less of total luminance.
