A heat-sink assembly is configured with two parts to grip a light-emitting element and produce a transverse force urging a surface of the light-emitting element toward a surface of the heat-sink assembly, which conducts heat away from the light-emitting element. Fastening mechanisms and a fulcrum inter-connect the heat-sink parts and produce the force that grips the light-emitting element. A configuration of the heat-sink parts creates a semi-enclosed space accessible through a gap. A configuration of elastomeric gaskets within the semi-enclosed space protects a portion of the space from intrusion of liquids or other environmental influences. Configuration of the heat-sink parts to form a recess in the heat-sink assembly provides protection of the light-emitting element from mechanical damage, and the recess may contain transparent materials that further protect the light-emitting element from detrimental environmental influences.

An LED growth light and method for providing light to plants incorporating an LED arrangement, a growth light housing, and a power source. The LED arrangement includes LEDs arranged in individually powered columns to provide relatively uniform disbursement of the light to the plants. The housing includes an accessory rail to attach a variety of optional accessories and internal cooling fins to cool the housing to prevent damage to the power supply and/or to prevent overheating the plants. In addition, the housing includes a fan and end caps which permit the movement of air for the displacement of heat and reduce the intake of moisture or debris into the interior of the LED growth light.

An LED (light emitting diode) panel. In particular, an LED panel that is part of a modular system used to construct a wall mounted LED video screen. An LED panel includes a chassis and an LED tile including a plurality of surface mount devices attached thereto. The LED tile is removably mounted to a front of the chassis, and further includes: a first power connector and a first data connector; and a connector assembly mounted on the chassis. The connector assembly includes a support board; a second power connector; a second data connector; and a biasing member arranged to urge the support board in a direction towards the front of the chassis, such that the second power connector and second data connector engage with the first power connector and first data connector, respectively.

A lighting apparatus includes a fixing unit, a lamp body, a base housing and multiple elastic units. The fixing unit has a central hole. The lamp body includes an inner semi-sphere housing, a rotation shaft and a light source. The base housing includes an external semi-sphere housing and a rotation connector. The rotation shaft is coupled to the rotation connector for the lamp body to rotate with respect to the base housing along a first rotation axis of the rotation shaft. The multiple elastic units are attached to the base housing. The multiple elastic units are elastically attached to the central hole for the base housing to rotate with respect to the fixing unit along a second axis. There is a tilt angle between the first rotation axis and the second rotation axis.

An airfield light, components thereof, and associated methods. The airfield light can include a baffle including a baffle body and one or more baffle members secured to the baffle body. The baffle members are configured to cover portions of a baffle window. At least one light source is mounted in association with the baffle and emits light out of the baffle window. The baffle members cover portions of the baffle window for blocking light transmission therethrough. A method of assembling an airfield light includes arranging a baffle to shroud a light assembly and removing a baffle member to permit light from the light assembly to emit through a portion of a baffle window opened by removing the baffle member. A baffle for an airfield light is also disclosed.

There is provided a light fixture comprising a light source. The light source has a housing terminating in a first end, and the housing has a housing connector proximate the first end. The housing also has a heat sink disposed inside the housing and a light emitter disposed inside the housing. The light emitter is positioned to allow a light emitted by the light emitter to exit the housing through the first end. The light source also has a connector in electrical communication with the light emitter. The housing connector is configured for reversibly securing the light source to one or more of: an adaptor reversibly securable to a trim configured for securing the light fixture to a substrate, and the trim.

A light bulb apparatus has a plurality of LED modules, a substrate, a driver circuit board, a plastic piece, a radiator and a lamp cap. The substrate has aluminum material for mounting the plurality of LED modules, a first connection end and a second connection end. The first connection end and the second connection end are electrically connected to the plurality of LED modules. The plastic piece with a guiding groove is used for inserting the driver circuit board. The radiator has a top plate and a side wall. The substrate is fixed on the top plate, and the side wall are connected to the plastic piece.

The instant invention relates to a miniature light emitting diode and accompanying mounting tab device. The instant invention seeks to provide a solution to light fixture designers by making a readily available and tightly compact light emitting diode mounting device. The instant invention provides for a mounting tab with a heat dissipating element to allow the use of high powered light emitting diodes that are small and compact.

A light-emitting device comprises a casing including an upper surface portion having one or more first through holes, and a front surface portion having an opening; a transparent member that closes off the one or more first through holes; one or more light-emitting elements that face the one or more first through holes, respectively, within the casing; and a lid member provided so as to close off the opening, wherein the casing is integrally formed using one material.

A light assembly mountable in an aperture formed in a railing or a light fixture. The light assembly may include a housing, first and second clamps, and first and second fasteners. The first fastener may couple the first clamp to the housing, and the second fastener may couple the second clamp to the housing. When the fasteners are rotated, the respective clamps pivot outward and move towards the railing or light fixture to retain the light assembly in the railing or the fixture. The light assembly may be removable from the aperture in the railing or the fixture.
