Generally, the present disclosure provides for a light engine, in particular a rack-mounted light engine that can be used in a lighting system. The rack mounted light engine can be positioned in an electronics component rack such a light distribution system using hollow light ducts may distribute the light over a large area, such as a data center. Such a light distribution can use a generated light more efficiently by directing the light to the fronts or backs of the electronics cabinet, rather than for general room illumination.

The luminaires of the present disclosure provide a slim profile and simple construction for use in a variety of lighting applications. A circuit board can have a plurality of light sources thereon, and a lens can at least partially encapsulate the circuit board to protect and electrically insulate the circuit board. When used, for example, in a lighted shelf application, power can be provided to the luminaire through shelf brackets along the side of the shelf panel.

An LED strip light for shelf signboards, comprises a strip-shaped lamp chamber, and an LED light-emitting module. The strip-shaped lamp chamber comprises a card board connecting edge, a non-transparent edge, an upper transparent edge and a lower transparent edge. The upper transparent edge is parallel to the laminate. The LED light-emitting module comprises at least one LED chip, and a strip-shaped reflective device. The strip-shaped reflective device comprises a first reflective surface and a second reflective surface. The first reflective surface reflects all the incident lights thereon toward the upper light transparent edge. The second reflective surface reflects all the incident lights thereon toward the lower transparent edge. Due to the structure of the strip light chamber and the LED light-emitting module, the LED strip light for shelf signboards allows the first row of the article display side facing the customers which are placed on the laminate and the space below the laminate to be illuminated so as to improve the user's shopping experience.

A supporting frame includes at least one supporting element, a base and a light-permeable pillar. The supporting element has a first through-hole. A cam is disposed in the supporting element and has a second through-hole and a turning portion. The second through-hole is disposed corresponding to the first through-hole. The base extends to form a sleeve. The light-permeable pillar passes through the first through-hole and the second through-hole and is inserted into the sleeve. The supporting element is capable of sliding along the light-permeable pillar. The turning portion is configured for pushing against an inner wall of the supporting element for fixing the supporting element on the light-permeable pillar.

A shelving system includes at least one vertically oriented shelf rail having a row of vertical slots leading to the shelf rail interior. In the interior, a bus bar includes conductors. A carrier element, such as a shelf element, is mounted on a bracket configured to hook into the shelf rail slots. A lighting device is attached to the carrier element or the bracket. A current collection device is fastened to the bracket and includes tap contacts that protrude from a housing and are disposed on the engagement section of the bracket. The tap contacts are resilient and disposed to be elastically pressed into the housing against a spring force when the bracket is being hooked into the shelf rail, pressed out of the housing when located in the shelf rail interior, and pressed against associated current conductors to establish an electrically conducting connection for the lighting device.

A smart home-care health device includes a health device including a master control board for household application. The master control board is electrically connected with multiple modules arranged in the health device. The detection modules connected to the master control board include a blood glucose detection module, a sleep detection module, and a heart detection module, which allow for acquisition of detailed and correct data of a target body through non-contact detections and allows, through feed-back, transmission to the master control board for judgment in order to establish personal dedicated message corresponding to the status of the target body and allow for message transmission to a clinic or a hospital and electrical appliances to allow family members to receive perfect home care of smart home.
