Provided in this disclosure is an apparatus for marking an implement, such as a snow plow. An elongated tubular member retains an illuminated member such an LED element within the interior. Conductor wiring connects a source of electrical energy to the LED. An enclosing cap includes a crimped end portion secured to the bottom end of the elongated tubular member. A cylindrical end portion has a hollow interior for admitting the conductor wiring for connection to the source of electrical energy. A perpendicular mounting bracket has a horizontal mounting surface and a vertical mounting surface, formed together at a right angle. The horizontal mounting surface is configured for connecting to the cylindrical end portion of the enclosing cap so that the elongated tubular member is disposed in a substantially vertical position. The vertical mounting surface is configured for connecting to a vertical portion of the snow plow.

An externally-hung lamp assembly includes a circuit board, a battery pack, an upper cover, a lampshade, a rubber ring, a lower cover, and a hook. The circuit board has a first hole and a plurality of light-emitting components. The battery pack is electrically connected to the circuit board and is configured to provide power needed for turning on the light-emitting components. The upper cover is disposed on the circuit board. The lampshade is disposed in a second hole of the upper cover. The rubber ring is disposed beneath the circuit board. The lower cover is combined with the upper cover, wherein the lower cover has a back surface. The hook is pivotally disposed on the back surface of the lower cover. By means of the foregoing configurations, the externally-hung lamp assembly can meet configuration requirements of multiple different application scenarios.

A lamp assembly includes a lamp, a medium and an assembling piece. The medium is configured to connect the lamp to a carrier. The assembling piece is disposed between the lamp and the medium, and is configured to connect the lamp to the medium, wherein the assembling piece includes a first part and a second part. The first part is configured to non-threadedly connect the lamp with the medium. The second part is configured to release the lamp from the medium.

A heat sink (10) comprising a plurality of parallel fins (12) and a plurality of plates (14). Each plate (14) is located between an adjacent pair of fins (12) and one or more securing members is provided to secure the fins (12) and plates (14) in contact. Each of the plates (14) is formed of a material being softer than the material of the fins (12) such that compression of the fins (12) and plates (14) deforms the surface of the plates (14) to improve thermal conductivity between adjacent fins (12).

A lighting apparatus includes a plurality of LEDs arranged in a row on an elongated wiring board; and a lens covering all the LEDs and controlling distribution of light emitted from each LED. An optical axis of the light emitted from each LED is orthogonal to the wiring board. The lens has a light emitting surface that controls distribution of the light emitted from each LED. When the light emitting surface is divided into at least three regions, the lens performs light distribution such that light radiated from a region is distributed in a direction tilted with respect to the optical axis of the light emitted from the LED. Thus, asymmetric distribution of light is achieved when the optical axis of the light from the LED is the axis of symmetry, and further, the luminous flux in the direction tilted with respect to the optical axis is increased most.

An apparatus, manufacture and method of illumination support being a single monolithic substrate with light emitting diodes mounted on the external sides of the monolithic substrate. The necessary circuitry for the LEDs is embedded in one or more rigid or flexible electrical substrate that is affixed to one or more of the external sides of the monolithic substrate. The two terminal ends of the monolithic substrate are designed to fit into the lamp sockets of an existing or new light fixture without the use of end caps or end socket adapters, which provides structural support for the monolithic substrate.

An apparatus and related methods includes a base attached to an upright structure (such as a street light pole), a mounting bracket that releasably engages the base while supporting a hanging banner, and an install adapter that releasably holds the mounting bracket and banner until the mounting bracket attaches to the base. A removal adapter facilitates disengaging the mounting bracket and banner from the base. The mounting bracket and install adapter (and removal adapter) are attached to a pole and engage (and disengage) remotely and without using separate fasteners, thus allowing a worker to install (or remove) banners high on the upright structure while standing on the ground. The base and mounting bracket have tapered shapes that wedgingly engage, secured by a spring-biased friction retainer. The install adapter and removal adapter have structures that facilitate remote install and removal of the mounting bracket from the base.

A light-emitting device includes: a holder having an elongate shape and flexibility; and a flat light-emitting element held by the holder and having a rectangular shape and flexibility. The holder includes a frame portion extending in a longitudinal direction of the holder, and a holding part protruding from the frame portion in a plan view. The frame portion of the holder and the flat light-emitting element overlap in a lateral-view direction, and the flat light-emitting element is joined to and held by the holding part.
