A lighting apparatus includes a light source, a driver, a light housing, an actuator unit, a light passing cover, and an external switch. The driver is used for converting an external power to a driving current supplied to the light source. The light housing is used for disposing the light source and the driver. The actuator unit is connected the driver for configuring a working status of the driver. The light passing cover is fixed to the light housing for a light of the light source to pass through. The external switch is mechanically connected to the actuator via a through hole of the light passing cover for the actuator to generate a control message to the driver. The driver controls the light source according to the control message to configure the working status of the light source.

A lift assembly guidance device enabling correct alignment of a lift pad relative to a vehicle includes a plurality of light emitters. The light emitters are mountable to a lift pad of a lift assembly so that the light emitters are disposed on a circumference of the lift pad. The light emitters selectively emit light orthogonally to the lift pad so that a surface of a vehicle, which is positioned over the lift assembly, is illuminated. The surface that is illuminated is that which would be contacted by the lift pad upon actuation of the lift assembly. The light emitters thus enable correct alignment of the lift pad with a structural element of the vehicle, such as a frame of the vehicle, and allow the vehicle to be safely lifted without damage to the vehicle.

The invention provides a LED luminaire comprising a frame shape formed of straight arms (12, 20) which each carry an LED arrangement (18, 26), and connections (30) which provide mechanical connection between the support arms (12, 20) and electrical connection between the LED arrangements (18, 26) of those arms (12, 20). The frame shape has a central opening (25) which assists cooling by convection and it can be manufactured using a low cost extrusion process.

An illumination assembly including a light pipe and a light supply for use in illuminating shelf dividers on a shelf. The light pipe includes a first end portion including a light inlet, a second end portion including a light outlet, and a body portion extending between the first and second end portions. The light supply directs light into the light inlet, whereby at least a portion of the light subsequently exits the light pipe through the light outlet. When the first end portion is positioned adjacent a rear edge of the shelf, the body portion extends from the rear edge to a front edge of the shelf. The light pipe is configured to transmit at least a portion of the light emitted by the light supply from the light inlet to the light outlet to illuminate an area adjacent the shelf front edge.

A locking channel has a series of inwardly extending locking tab members. The base section of a neon lamp is positioned within the locking channel and secured and locked in place by means of the locking tab members. This system can be used with locking channels which are straight, angled or of any curved configuration.
