Abstract: A sunshine recorder has: a lens that emits, as projection light, natural light incident from half of the celestial sphere; a sensor that photoelectrically converts the projection light projected onto a light receiving surface, and outputs the photoelectrically converted projection light; and a determination circuit that determines the presence or absence of sunshine on the basis of an output of the sensor, wherein the sensor has a plurality of detection areas on the light receiving surface and is configured to output a signal corresponding to the intensity of the projection light incident on each of the detection areas, and the determination circuit removes a scattered light component included in the projection light on the basis of a difference operation of the signal output from each of the detection areas to extract only a direct light component to be included in the projection light at the time of incidence of sunlight.

Abstract: A wireless battery-powered daylight sensor for measuring a total light intensity in a space is operable to transmit wireless signals using a variable transmission rate that is dependent upon the total light intensity in the space. The sensor comprises a photosensitive circuit, a wireless transmitter for transmitting the wireless signals, a controller coupled to the photosensitive circuit and the wireless transmitter, and a battery for powering the photosensitive circuit, the wireless transmitter, and the controller. The photosensitive circuit is operable to generate a light intensity control signal in response to the total light intensity in the space. The controller transmits the wireless signals in response to the light intensity control signal using the variable transmission rate that is dependent upon the total light intensity in the space. The variable transmission rate may be dependent upon an amount of change of the total light intensity in the space. In addition, the variable transmission rate may be further dependent upon a rate of change of the total light intensity in the space.

Abstract: The invention relates to a method for testing the operability of a motor vehicle (10) with a headlamp (12) which comprises a laser (14) for generating by means of which a converter (16) for emitting converted light is excited, which is emitted by the headlamp (12) for generating a predeterminable light distribution (18) on a surface area (20) in a surrounding area of the motor vehicle (10), wherein the predeterminable light distribution (18) is set by a control device (22) of the headlamp (12). The object of the invention is to check the condition of the converter (16). A test pattern (26, 30) is set by the control device (22) as light distribution (18). The test pattern (26, 30) is detected on the surface area (20) by means of an optical detection device (24) of the motor vehicle (10). The detected test pattern (26, 30) is compared with at a predetermined reference pattern by an evaluation device (28) of the motor vehicle (10). The invention also relates to a motor vehicle (10), which is designed to carry out such a method.

Abstract: Systems and methods are disclosed to translate a desired light level at a particular task location to a light level measured by a light sensor at a non-task location such as a wall location or a light switch location. For example, the light measured on the wall may be used to accomplish daylighting energy savings while maintaining a relatively constant illuminance value at the task location. Alternatively or additionally, up/down button presses at the wall location may be used to provide constant or consistent illuminance changes at the task location.

Abstract: An aquarium photometer system includes a housing unit, an arm, and a mirror. The housing unit includes a light sensor configured to sense light incident on the light sensor and to convert the incident light to a signal. The housing unit also includes an operational amplifier including a first input node, a second input node, and an output node. The operational amplifier is configured to: receive the signal at the first input node, amplify a difference between the signal at the first input node and a signal at the second input node by a gain factor, and output the amplified signal on the output node. The housing unit also includes a potentiometer connected to the operational amplifier and configured to regulate the amplified signal; and a display connected to the potentiometer and configured to show an intensity of light detected by the light sensor based on the regulated amplified signal. The arm at a first end is connected to the housing unit and configured to move the housing unit around an aquarium case. The mirror is located on a bar and positioned within the aquarium in front of the light sensor and at a focal distance from the light sensor and configured to increase an amount of light incident on the light sensor.

Abstract: Techniques are disclosed for maintaining consistent lumen output of a lighting assembly over time. By maintaining a consistent lumen output, it is possible to maintain acceptable color stability where color mixing of multiple outputs is used. The lighting assembly may be any lighting configuration that might suffer from lumen depreciation and/or color drift over time, and may include any type(s) of light source(s) that may be monitored and driven accordingly. The lighting assembly, in addition to light source(s), includes a photo detector and a directed light source, such as a laser. The directed light source provides a golden sample for use in calibrating the photo detector, which in turn monitors lumen output of the light source(s). Drive signals are adjusted to account for lumen depreciation of the monitored light source(s).

Abstract: To realize collective measurement of ultrawide-band optical signals which have exceeded an electrical band limit. This photodetection device (100) comprises: a time-delay adjustment means (10) into which is input an optical signal that is a detection object; an optical frequency comb generator (20) that generates an optical frequency comb; a photomixer (30) that photomixes optical signal series which are sequentially output from the time delay adjustment means (10) and which were subjected to time adjustment, and the optical frequency comb signal which is output from the optical frequency comb generator (20); and a photodetector (40) that detects the mixed signal output from the photomixer (30). The time delay adjustment means (10) performs time adjustment on the optical signal series so that each of the time adjusted optical signal series is photomixed with the optical frequency comb at different timings in the photomixer (30).
