摘要： Various implementations disclosed herein include a method for aiding disinfection of a room. The method may include collecting, by one or more sensors in a disinfection system, activity data in the room. A computing device or output device may identify one or more hot spots from the activity data, in which the one or more hot spots indicate areas in the room for cleaning, and generate a contamination map containing the one or more hot spots. The output device may output the contamination map to an output device for viewing by a user.

摘要： An automotive lighting system (41) includes an automotive lamp having an LED array (14) and a lens (34). The lens (34) images a square field of illumination (101) into rectangular field of illumination (48) to support adaptive front lighting in an automotive environment (28). The lens (34) includes light-transmissive first, second, and third regions (64, 66, 68), and a baffle (70) adapted to obstruct light from spreading between the light-transmissive first, second, and third regions (64, 66, 68). The baffle (70) is disposed between the LED array (14) and light receiving surfaces (98, 104, 110) of the light-transmissive first, second, and third regions (64, 66, 68). The lens (34) enables imaging of an approximately rectangular field of illumination (48) from a single chip (12), reducing cost and cooling needs of adaptive front lighting systems.

摘要： Techniques are disclosed for enhancing indoor navigation using light-based communication (LCom). In some cases, an LCom-enabled luminaire configured as described herein may acquire user data from a local computing device and relay it to a server that tracks and analyzes the data to assess statistics for the luminaire's local spatial environment. The disclosed luminaire may receive from a local computing device a request for indoor navigation to a target of interest, such as a remote computing device. The luminaire may relay that request to a downstream luminaire, which delivers the request to the target. The target may respond with data that allows for tracking of its location and indoor navigation thereto, regardless of whether that target is moving or stationary. In a network of such luminaires, data distribution via inter-luminaire communication may be provided, for example, via an optical interface or other wired or wireless communication.

Lamp module 32 has base 2 defining central post 4, post 4 defining internal first air passage 401. Base and post act are heat sinks. Fan 8 is disposed within base 2. Circuit board 14 having LED arrays 17 is mounted inside post 4 in fluid communication with first air passage 401. Base 2 defines second air flow passage 405 exterior of post 4, second air passage 405 being oriented to direct air past mounting flange 42. Base 2 further defines third air passage 410 rearward of mounting flange 42 and radially outward from second air passage 405. Mounting flange 42 may be keys coupleable to slots 15. A method of directing an air stream through slots 15 in reflector socket 121 is described.

摘要： Automotive lamp (10), preferably a backup lamp, includes first lamp (12) and plural LEDs (26a-n). The lamp (12) comprises light-transmissive material, first and second opposed end surfaces (16, 18), a source side (20) and an emission side (22) each extending between end surfaces (16, 18), source side (20) facing LEDs (26a-n), and emission side (22) having an aspherical surface facing area to be illuminated (24). The elongated optical lens (14) has a length (L) extending, parallel a first horizontal X-axis, between the end surfaces (16, 18) that is greater than a thickness along second horizontal Z-axis and a height along vertical Y-axis (X-, Y-, and Z-axes being mutually orthogonal). Elongated optical lens (14) defines focus line segment (FS) extending parallel the X-axis, and preferably bends LED light below a horizontal XZ plane, i.e. back towards source side (20). Backup lamp (12) provides to camera (52) ground illumination of minimum 1 lux at distances 0-6 meter when mounted to vehicle at heights between conventional bumper and roofline.

摘要： A solid-state automotive vehicle headlamp includes a solid-state light source (SSLS), a clamshell reflector, and a reflector optic. The clamshell reflector includes a reflective surface defining a clamshell cavity with an open end facing a field to be illuminated. The reflector optic is defined by a portion of a spherical surface in surrounding relation to the SSLC. The reflector optic defines a light-transmissive window permitting a direct line-of-sight transmission of light generated by the SSLC to the reflective surface of the clamshell reflector. The reflector optic further includes a reflective region at least partially surrounding the light-transmissive window and configured to reflect light generated by the SSLC and directed at the reflector optic back towards the SSLC. The reflector optic redirects some of the light emitted by the SSLC through the light-transmissive window towards the clamshell reflector to create a more controlled beam pattern and increase the overall light output.

摘要： A solid state driver to adapt current ripple characteristics therein, at least partially based on operating characteristics of a solid state lighting device operated by the driver, is provided. The driver senses operating voltage, operating current, or a combination of operating voltage and operating current of a solid state lighting device. The driver stores pre-determined current ripple percentage settings in a data structure, for example, in a controller circuit. The driver selects and implements one of the pre-determined current ripple percentage settings based on one or more of the sensed operating characteristics of the solid state lighting device, to improve efficiency, to reduce the operating frequency, and/or to lower the operating temperature of one or more components of the driver.

摘要： A laser-activated remote phosphor (LARP) target with a first layer having a first index of refraction and a phosphor dispersed within the first layer. A second layer which has a second index of refraction different from the first index of refraction and adjoins the first layer at an interface. The first index of refraction is higher than the second index of refraction such that the interface is configured to at least partially reflect light emitted from the phosphor.

摘要： A method for controlling a chromaticity of total light provided by a lighting system includes detecting the total light by a sensor system, determining a component of the total light that is attributable to uncontrolled light, and selecting a calibration for a sensor based on the uncontrolled light, and using the calibration to adjust the output of the sensor system. The calibration tables may be based on spectral responsivity of the sensors in the sensor system and calibration functions rather than physical light sources. Relative intensities of controllable light sources having different xy values are then adjusted to cause the total light provided by the lighting system to approximate a target chromaticity. A daylighting system implementing this method includes controllable light sources with different xy values. The intensities of the controllable light sources are adjusted to augment sunlight to control the chromaticity of total light provided by the daylighting system.
