A method for manufacturing a light guide plate (LGP) positioning block thereof includes providing a positioning block body of a LGP positioning block and filling and sealing a liquid in a receiving compartment formed in the interior of the positioning block body. The liquid is expandable with a drop of temperature so as to increase a volume thereof and thus enlarge a size of the positioning block body through elasticity of the positioning block body. In this way, the LGP positioning block is adjustable with the variation of the surrounding temperature so as to achieve effective positioning of the light guide plate and providing high reliability of a liquid crystal display device including the light guide plate.

A retrofit assembly includes at least first and second lighting modules, and at least a central hub positioned between the first lighting module and the second lighting module. Each lighting module includes a tray extending along a longitudinal axis and supporting a solid state light source on a seat defining a plane, a set of legs extending from each side of the seat, and a set of wings extending from the legs and parallel to the plane of the seat, the wings including first and second groups of mounting holes. First and second lenses might be provided to extend across a portion of the seats.

A modular solid state high bay lighting fixture is provided herein which includes at least two lighting modules, each including a body configured to define an open channel along one face thereof with a lens or diffuser at least partly overlying each of the open channels. Bottom and upper plates extend between the lighting modules with the upper plate being spaced from, and at least partially overlying, the bottom plate so that a chamber is formed therebetween. The bottom plate is movable relative to the bodies of the lighting module from a first state, where the bottom plate is edge supported, to a second state, where one edge is clear of the bodies allowing the bottom plate to rotate.

A light fixture and a method of making a light fixture include a light-permeable tube, at least one end cap pushed onto a free end of the tube for closure, and a driver device received at least partially in the tube and held in the tube by the end cap for driving a light module arranged in the tube. The end cap is fastened on the tube by an expanded adhesive and the driver device is fastened to the end cap or to the tube by the expanded adhesive.

The present invention relates to a device for attaching and detaching a handle of a surgical light which is a medical lighting apparatus. The device, in the handle which is inserted into or separated from a surgical light shaft in a female-male coupling manner, comprises: a lock pin which protrudes in the axial direction of the surgical light shaft and is inserted into a lock hole formed on the handle so as to prevent the handle from being separated; a pin spring, supported on the surgical light shaft, for providing elastic force so that the lock pin protrudes to the outside of the surgical light shaft; a separation button which is provided on the outside of the handle and, when an external force for separating the handle from the surgical light shaft is applied, is pushed so as to enable the lock pin to be separated from the lock hole of the handle; and a button support body for supporting the separation button on the handle so that the separation button is movable to a certain degree. Therefore, the device prevents cross-infection which can occur while moving the surgical light during an operation, thereby enhancing safety and reliability of the surgical light.
