A high-insulation integrated plastic lamp holder that does not require traditional American and European-standard copper lamp holders, comprising a high-insulation plastic body formed by injection molding. The top of the high-insulation plastic body is provided with a barrier, a first conductive component slot, and a second conductive component slot, and the barrier is located between the first conductive component slot and the second conductive component slot. The first conductive component slot and the second conductive component slot are inserted into positive and negative conductive sheets correspondingly, and the assembly of the lamp holder is simpler, which facilitates automatic production, thereby greatly improving the daily production capacity and insulation, and lowering the cost of production.

A lighting assembly can include a lamp module group including a first housing defining a protruding column, the first housing defining a cavity, the first housing defining a housing opening to the cavity positioned opposite from the protruding column; a power supply driving module positioned within the cavity; and a first concentric terminal connected in electrical communication with the power supply driving module, the first concentric terminal extending through the protruding column; and a second housing including a second concentric terminal, the second housing receiving a portion of the first housing, the second concentric terminal connected in electrical communication with the first concentric terminal, the second concentric terminal configured to supply power to the power supply driving module through the first concentric terminal.

Example embodiments relate to luminaire systems with improved fastening means. One example luminaire system includes a first support provided with a recess. The luminaire system also includes a plurality of light sources arranged on said first support. In addition, the luminaire system includes a second support arranged opposite said first support. Further, the luminaire system includes one or more optical elements provided to said second support, and associated with the plurality of light sources. Additionally, the luminaire system includes a fastening element that includes a head portion and a rod portion. The second support is provided with a through-hole for receiving said head portion. Said rod portion extends through said through-hole and said recess in order to be fixed in the first support and/or in a portion of the luminaire system. The second support is provided with a protruding portion.

A QCL module according to an embodiment includes a package accommodating a QCL element and provided with a window material for extracting a laser beam emitted from the QCL element to the outside, a lens hold member for holding a lens on which the laser beam output from the window material is incident, a cooling fan for cooling the package, and a base for holding the package, the lens hold member, and the cooling fan. The package and the lens hold member are fastened together to the base by a common screw member.

A LED bulb apparatus has a bulb shell, a head cap, a driver circuit and at least one light strip. The bulb shell has a light passing shell and a bottom portion. A head cap has a neck portion, a first electrode and a second electrode. The neck portion of the head cap is connected to the bottom portion of the bulb shell forming a container space. A fluorescent layer covers the multiple LED modules. The driving current is transmitted via at least one of the top end and the bottom end of the light strip to the LED modules. The substrate has a light transmittance less than 50%.

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 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.

Embodiments may utilize a series of exposed fins, which increase the surface area of the heat sink creating additional air flow. As hotter air rises within the system, cooler is drawn into the heatsink. The fins may be exposed on both sides of the longitudinal axis, allowing cooler air to be drawn towards the longitudinal axis above the heatsink and flow upward. This process may cool the fins. Additionally, the spacing between the fins may have to be wide enough to allow for air to freely enter the heatsink.

Light engine modules include a support member and a solid state light emitter, in which (1) the emitter is mounted on the support member, (2) a region of the support member has a surface with a curved cross-section, (3) the emitter and a compensation circuit are mounted on the support member, (4) an electrical contact element extends to at least two surfaces of the support member, and/or (5) a substantial entirety of the module is located on one side of a plane and the emitter emits light into another side of the plane. Also, a module including means for supporting a light emitter and a light emitter. Also, a lighting device including a housing member and a light emitter mounted on a removable support member. Also, a lighting device including a module mounted in a lighting device element. Also, a method including mounting a module to a lighting device element.
