A lighting module includes a heat sink with a sidewall and a partition defining two cavities, a LED light source disposed in one cavity to emit light, a driver module disposed in the other cavity with driver circuitry to provide electrical power to the light source, and an optical assembly to provide a desired emission profile. The optical assembly is field-changeable and includes a cover lens with snap-fit connectors to facilitate removal and replacement. The optical assembly further includes either a reflector coupled to the cover lens or an optical lens coupled to the heat sink via an optic holder. In some examples, the driver circuitry facilitates dimming of the light source. The heat sink also dissipates heat generated by the light source and the driver circuitry to maintain desired operating temperatures and thereby facilitate increased light output.

A lighting apparatus includes a light passing cover, a light strip, a heat dissipation plate, a manual switch, a driver and a bottom cover. The light passing cover defines first elongated cavity. The light strip is mounted with multiple LED modules. The heat dissipation plate is used for mounting the light strip on a first side of the heat dissipation plate. The manual switch is disposed for selecting a switch setting. The manual switch is placed on the first side of the heat dissipation plate. The driver converts an external power source to a driving current supplied to the multiple LED modules. The driver is electrically connected to the manual switch for controlling the driving current supplied to the multiple LED modules to adjust an output light of the multiple LED modules according to the selected switch setting. The bottom cover defines a second elongated cavity.

A lighting module includes a heat sink having a sidewall and a partition that define a first cavity and a second cavity. A driver enclosure is disposed in the first cavity to electrically insulate a driver from the heat sink. The driver enclosure substantially fills and covers the first cavity. A light source that emits light is disposed in the second cavity together with an optical element that redirects the light. A retaining ring/optic cover covers and encloses the second cavity. The lighting module is shaped and/or dimensioned to fit into a space having a width less than 2.4 inches, a height less than 2.25 inches, and/or a volume as small as 18 cubic inches. The heat sink may also include a receptacle to couple a trim to thermally and electrically couple the trim to the heat sink to dissipate heat and to ground the trim.

An asymmetrical linear lens directing light at a limited solid angle includes a first solid profile section being a right trapezoid having a short and longer base side and two side legs. A second solid profile section is a non-right trapezoid having a short and longer base side and two side legs. The longer base side of the first solid profile section and the shorter base side of the second solid profile section coincide. One of the two side legs of the first solid profile section and one of the two side legs of the second solid profile section lie on a straight line enclosing a first angle with the longer base side of the second solid profile section. The other side leg of the second solid profile section is angled outward in relation to the other side leg of the first solid profile section by a second angle.

A linear luminaire includes a linear channel defining an interior space and a linear light inset configured for being inserted into the channel in the interior space. The light inset includes a cover and a printed circuit board fixed to the cover. The printed circuit board supports a plurality of light emitting diodes. The cover base wall includes a translucent portion. The light emitting diodes are arranged for emitting light through the translucent portion. The cover includes two cover connectors, each configured for being snapped into the channel to hold the cover in the interior space. The cover connectors are on an opposite side of the printed circuit board as the translucent portion.

The present disclosure provides a light source module and a lighting device using the same. The light source module includes: a support member, to be disposed on a lighting device and provided with a first positioning portion; a light source mounting member, having a second positioning portion to be jointed with the first positioning portion through shape matching, where the light source mounting member has a bearing surface for disposing a light source electronic component; and a lens member, covering the bearing surface and connected to the support member in a positioned manner.

An optical light source cover configured to be fixed at a reaction bearing, the optical light source cover including an interlocking element configured to attach the optical light source cover at the reaction bearing, wherein the interlocking element includes an interlocking arm, wherein the interlocking arm extends from the optical light source cover in an insertion direction of the optical light source cover into the reaction bearing and includes a free end that is in front in the insertion direction and a connected end that is connected to the optical light source cover, wherein the interlocking element includes a first interlocking hook that is wedge shaped, wherein a first wedge tip of the first interlocking hook is oriented in a direction towards the free end of the interlocking element.

A modular lighting assembly uses LED banks as the light sources. The assembly allows the power supply and LED banks to be independently replaced. The assembly uses a power supply that is separated from the LED banks and electrically connected to the LED banks with a plug connector that may be unplugged and plugged back in to allow the power supply or LED bank to be independently and readily replaced. The assembly provides for easy replacement of the different components of the assembly. One feature that makes the components easier to replace is that the light modules and/or the power supply may be carried by the housing that is removable from the base mount that is secured to a mounting structure such as a wall or ceiling.

A lighting apparatus for use as a surgical headlamp is disclosed. A light emitting diode is positioned in a recess within a frustoconical, thermally-conductive heat sink that has a several circumferential ridges to provide a desired surface area for heat transfer. The diode and the heat sink are provided in a housing that also includes a fan for drawing ambient air into the housing to contact the heat sink and exhausting heated air. A lens is snap-fit into a slide that frictionally engages the interior of the housing, allowing a user to adjust the spacing between the light emitting diode and the lens as desired. Personal cooling apparatuses usable with the lighting apparatus are also described. Auxiliary undergown switches are also described as are personal cooling apparatuses.

A reversible LED lamp has a fixed support including first and second plate bodies. One side of the first body is connected to the second; the other is connected to a first limiting member. A rotating support includes a third plate body and rotating support member. One side of the third body is connected to a first rotating portion; the other side is connected to the rotating support member, below the second and third bodies. A side of the rotating support member close to the second body is flush therewith. The plate bodies and rotating support member form a power supply installation space. A light-emitting assembly is in a light source installation space in the rotating support member. When a power supply in the power supply installation space is repaired/replaced, the rotating support is unfolded. The rotating support is rotatable in the fixed support, which has an avoidance groove.
