A lighting device may be provided that comprises: a cover; a member comprising a first placement portion, a second placement portion and a guide disposed between the first placement portion and the second placement portion; a light source module disposed on the first placement portion; a heat sink comprising a first receiver and a second receiver, the first receiver being defined by a flat surface and a plurality of heat radiating fins extending from an edge portion of the flat surface; and a circuitry disposed in the second receiver; wherein the second placement portion is disposed in the first receiver, wherein a first portion of the guide is couple to the cover and a second portion of the guide is couple to the heat radiating fins of the heat sink, and wherein the guide is spaced apart from the flat surface, the guide contacts the heat radiating fins, and the guide is disposed on the heat radiating fins.

A display device includes a curved display panel, a light source unit, a curved light guide plate, a support frame disposed under the light guide plate and including a curved upper surface, a first magnetic member disposed at at least one edge of the upper surface of the support frame, and a second magnetic member disposed at at least one edge of a surface facing the upper surface of the light guide plate and facing the first magnetic member.

The invention relates to a light diffuser casing comprising an enclosure defining a cavity and provided with a closable opening configured to enable a headlamp to be inserted inside the casing. A light diffuser is arranged in the casing to receive a light beam coming from the headlamp and to make said beam diffuse on the enclosure. The light diffuser is made from a translucent or transparent material so that said beam passes through it, and the enclosure is made from a translucent material. The invention also relates to a method for using the casing.

Disclosed is a bubble lamp for quasi bubble flow. A buffer made of a transparent material having an excellent heat conduction effect and impact moderating performance is configured on the top of the bulb configured on the main body of the bubble lamp or on the bottom of the glass tube configured on the upper cover, and the casing made of a transparent and no-easily-broken material is put around the glass tube, thereby abutting the glass tube against the top of the bulb across the buffer when the upper cover is covered on and coupled to the main body, allowing both the glass-made bulb and glass tube to be buffered by the butter and thus to block or decrease an impact when a contact force is too large upon assembly, and preventing the bulb or glass tube from being broken.

A blank for an enclosure for a recessed light fixture in an attic comprises a sheet of a thermally resistant material subdivided into a plurality of square panels by living hinges. The panels are foldable to provide a housing for the recessed light fixture. A package of blanks is constituted by a pair of such sheets, each sheet having a panel pivoted against an adjacent panel of same sheet in a back-to-back relationship when the sheets are juxtaposed relative to one another.

A sensor module for a lighting fixture includes a housing configured to be mounted to a lighting fixture, a light sensor mounted in the housing, and a sensor cover over the light sensor. The sensor cover includes a parallel surface and an angled surface. The parallel surface is parallel to a task surface within an area of interest, and includes a first number of lens sections, each of which are configured to focus light from a different portion of a first subset of the task surface to the light sensor. The angled surface includes a second number of lens sections, each of which extend from an edge of the parallel surface to form a facet of the angled surface and are configured to focus light from a different portion of a second subset of the task surface to the light sensor.

The present invention relates to a cover assembly for the flashlight which is similar to a slipcase that enables it to provide a protective cover to the flashlight at the time of its use for any work. The cover assembly herein is made up a body section which further comprises a coupling mean wherein; the coupling means have a self-adjustment property according to any shape and size of the flashlight. The cover assembly herein acts as a protective cover for the flashlight.
