A system for detecting a positional status of a vehicle treatment device is provided. The vehicle treatment device is rotatable relative to a support structure. A plurality of proximity sensors are disposed on the support structure. A flag is rotationally fixed to the treatment device and is configured to activate at least one of the sensors during a predetermined movement to determine orientation. In response to a deviation, external force, or impact on the treatment device, the flag pivots or moves relative to the support structure and sensors in an unexpected manner, causing a deviation from an expected activation of the sensors according to the predetermined movement.

A pendant lighting fixture can include an outer casing, a hollow body positioned within the outer casing, a motion generator positioned within the hollow body, and an illumination assembly within a chamber formed by a cover. An upper part of the hollow body is configured to be coupled to a hanging mechanism, and a lower part of the hollow body is removably coupled to the cover. The motion generator comprises a container, a magnetic coil configured to generate a magnetic field, and an object movably responsive to the magnetic field move within the container so that a movement of the object of the motion generator by the magnetic field affects an illumination effect of the illumination assembly.

A novel pool light comprises a power supply device, a lighting device, and a power cable mounted between the power supply device and the lighting device. The lighting device comprises a light fixture and a cable winding mechanism for winding the power cable. The cable winding mechanism comprises a rotating member having one side fixedly connected to the light fixture and a base plate rotatably connected to the other side of the rotating member, and a recess between the periphery of the rotating member and the periphery of the base plate forms a cable trough allowing the power cable to be wound therein.

First light is incident on a diffuser, and scattered light emerges from the diffuser. The diffuser includes one light incident surface on which the first light is incident in a first direction and a first light transmitting surface. The light incident surface is formed on an end surface of the diffuser. First transmitted light emerges from the first light transmitting surface. Second transmitted light emerges from second light transmitting surface that is a surface other than the first light transmitting surface of the diffuser. Intensity of the first transmitted light increases as a direction in which the first transmitted light emerges approaches the first direction. Correlated color temperature of the first light is lower than correlated color temperature of the first transmitted light and higher than correlated color temperature of the second transmitted light.

This document describes techniques directed to a modular floodlight system with supplemental motion detection. The modular floodlight system includes a camera unit magnetically coupled to an accessory unit. The accessory unit includes passive infrared, PIR, sensors that expand and supplement motion-detection capabilities of the camera unit. For example, the accessory unit PIR sensor provides a PIR field of view, FOV, that is different than the PIR FOV of the camera unit's PIR sensor. Motion detected in either or both of the PIR FOVs is used to cause of change in functionality of the camera system such as, for example, activating image capture by the camera unit and/or activating one or more lights on the modular floodlight system.

Disclosed are example embodiments of a five-device-in-one double-stacked internal-gutters, which is economical to produce, is easy to ship, and can be quickly and easily assembled and disassembled. Particularly, the present invention relates to five-device-in-one anti-leaking noise-canceling anti-twisting anti-warping anti-vibrating double-locking double-core double-deck double-stacked internal-gutters (for being adapted to pergola, RV, house, solar panel, and concert stage), which comprise: Anti-leaking noise-canceling rainwater-shedding rainwater-guiding clamp-shield roof system, anti-twisting anti-warping anti-vibrating double-locking double-core double-deck double-stacked-internal-gutter systems, Double-gutter-supporting-and-locking corner parapet-post systems, Double-gutter-supporting-and-locking center parapet-post systems, and 6 expandable foot-locking sleeve-bolt systems.

A traffic signaling system comprises a traffic light that includes an inner light arrangement, and an outer light arrangement bordering the inner light arrangement. The inner light arrangement comprises a red inner light, an amber inner light, and a green inner light which are linearly arranged; the outer light arrangement comprises at least one of a red tube light, an amber tube light, and a green tube light; and an inner light in the inner light arrangement illuminates simultaneously with a tube light of a matching color in the outer light arrangement during an active state for the respective color.

A light-mixing cover includes a base plate and multiple lens groups. The base plate has a lens plane, and the multiple lens groups are arranged on the lens plane in a first direction. Each of the lens groups includes multiple lenses arranged at intervals in a second direction perpendicular to the first direction. At least one of the lenses is different in structure from a lens adjacent thereto.

An electronic device with light-indicating function is provided. The electronic device includes a substrate, a first light source, a second light source, and a light guiding element. The substrate includes a first surface and a second surface, wherein the first surface is opposite to the second surface. The first light source is disposed on the first surface of the substrate, wherein the first light source faces the first direction, and the first light source provides a first light beam. The second light source is disposed on the first surface of the substrate, wherein the second light source faces the second direction, the second light source provides a second light beam, and the first direction is not parallel to the second direction. The light guiding element includes a first section and a second section.

In one embodiment, a LED module comprises a heat sink, a light source, a lens structure configured to enclose the light source by means of a sealing material, and a fastener assembly configured to removably attach the light source and the lens structure to the heat sink. The lens structure comprises a groove and one or more lenses. The groove surrounds the one or more lenses and is configured to receive the sealing material such that the sealing material seals a gap between the lens structure and the light source without attaching to the heat sink.
