A lamp installation structure of a ceiling fan has a first base connected to a fixing seat of the ceiling fan and a second base connected to a lamp. The first base is provided with a plurality of positioning members. The second base has grooves and guide rails corresponding to the positioning members for insertion of the positioning members. The guide rails are provided with a plurality of elastic members to elastically press against the positioning members. Thereby, through the positioning members being retained to the guide rails, the lamp installation structure of the ceiling fan has the advantages of quick installation and increased stability of the ceiling fan.

A backlight source module and a display device are provided. The backlight source module includes a back plate structure and a rubber member. The back plate structure includes a bottom plate, and a first side plate and a second side plate respectively connected with the bottom plate, and the first side plate and the second side plate oppose each other. A light-emitting portion, a light-guiding component and the rubber member are sequentially disposed on the bottom plate along a first direction pointing from the first side plate to the second side plate. The rubber member is only disposed at the second side plate.

A lighting device system includes at least one lighting device module having a module housing configured to be inserted at least partially through an opening in a panel, and at least one heat sink member having a contact surface. The at least one heat sink member is located adjacent the opening in the panel. The module housing is held in contact with the contact surface of the at least one heat sink member when the module housing is inserted at least partially through the opening in the panel in an installed state. The module housing is configured to be selectively withdrawn from the contact surface of the heat sink member, through the opening in the panel.

A recessed light fixture has a heat sink and a removable light engine assembly. A thermally conductive base of the light engine assembly has an LED and has a thermal interface adapted for thermal coupling to a thermal interface of the heat sink. A mechanical connector in the enclosure can connect the base of the light engine assembly to the heat sink and couple the thermal interfaces of the light engine assembly and heat sink. The base of the light engine assembly is insertable through an opening in the ceiling aligned and can be urged into connected and disconnected states, from within the room, with a minimal clearance between the opening in the ceiling and the base, whereby the light engine assembly can be replaced or serviced from within the room without disturbing the ceiling and without the use of a large diameter trim.

The utility model discloses a multi-angle lighting lamp, which comprises: a lamp holder, a plurality of lamp boards and a plurality of protective covers; a plurality of protective covers are connected to the lamp board one by one, and the protective covers are covered on the lamp beads; there is a heat sink between two adjacent protective covers, and the heat sinks are communicated with the lamp cavity, so that the convection channel can be formed inside the lamp cavity, so that the air flow can directly and effectively blow the heat dissipation part, and then the air flow can better take away the heat of the dissipation part, thus, the heat on the lamp board is effectively discharged through the heat dissipation part, so the overall heat dissipation efficiency of the lamp has been greatly improved.

Provided is a modular heat management apparatus for an out-door lighting system including a plurality of lighting elements, that includes a housing including an interface portion disposed at a top surface of the housing, an attachable heat sink to be disposed and mounted onto the interface portion and configured to dissipate heat generated by the outdoor lighting system, and a fixing element configured to attach the attachable heat sink to the interface portion and to apply contact pressure thereto.

A system for heat and light management for indoor horticulture is described. More particularly, a system including light sources, a light distribution chamber, and circulating water is described.

There is disclosed a forward cooling headlight comprising a body, a lens coupled to the body and a heatsink coupled to the body. There is also a heatpipe and at least one light. The light is coupled to the heatsink, wherein the heatpipe is coupled to the heatsink at a first end, and to the body at a second end. The heatsink draws heat away from the light, via the heatpipe and towards the body. There can be at least one synthetic jet coupled to the heatpipe to aid in cooling the light. In addition, in at least one embodiment, there can be at least two lights with at least two different drivers with a first driver driving a first light and a second driver driving a second light wherein when each of the lights is lit it is capable of generating a different focal point.

A runway-embedded flash lighting device, includes a body configured to be embedded in a runway; a ceiling member including a flash emission window and disposed in an upper opening of the body and configured to be exposed to a runway surface when the body is embedded in the runway; a light guide member disposed in the flash emission window; an LED flash light source disposed inside the body and configured to emit a flash toward the light guide member; and a heat conducting member, wherein the light guide is configured to allow the flash emitted from the LED flash light source to be emitted from the flash emission window, the heat conducting member is disposed inside the body and includes a first part in contact with the LED flash light source, and a second part in contact with the ceiling member.
