A floodlight includes a light source, a support member that supports the light source, and a fan that cools the light source by generating an air flow on a surface of the support member. The light source is supported on a front face of the support member and emits light forward with respect to the support member. The fan is disposed rearward of the support member, at a position facing the support member.

The present disclosure relates to a fan lamp, which includes a base, a first light source module and a fan; the base includes a first side and a second side which are away from each other, a fan groove is formed at the first side, and a first light source setting area is arranged at the second side, an air outlet duct is further arranged on the base and communicated with the fan groove and the second side, and an opening, at the second side, of the air outlet duct surrounds the first light source setting area; the light source module is arranged in the first light source setting area, and the fan is arranged in the fan groove.

A junction unit adapted for use in a lighting balloon apparatus is provided. The junction unit comprises a body, a first attachment region disposed on the body to couple to one or more lighting modules, and a second attachment region disposed on the body to couple to a header cable that provides power to the one or more lighting modules.

A combination axial fan and LED lighting system configured to fit into the footprint of a standard ceiling tile. The system includes a housing container and an axial fan. The fan has a fan cavity including air diversion mechanism to direct air from the fan cavity toward the lighting and fan components. The invention includes an airflow surface to direct air existing the fan cavity along an LED light fixture.

A system for upgrading and retrofitting existing streetlights. The system enables conventional streetlights using sodium vapor, and other conventional lighting technologies, to be upgraded to more energy efficient and long-lasting LED lighting. At the same time, cellular and wireless communications can be added to the streetlight to provide additional bandwidth over that provided by conventional cell towers. The system can offload bandwidth in otherwise overloaded areas, such as densely populated urban areas. The system can include mini- or micro-cellular routers, GPS, Wi-Fi, Bluetooth®, and other micro cellular and wireless technologies. The system can include a light fixture styled to look like existing conventional light fixtures and can be retrofitted to existing streetlight poles and mounts with little, or no, modification to the pole and wiring.

The present invention provides a finned heat-exchange system, comprising a heat dissipation chamber, a fin, an air guide element and a base, wherein the heat dissipation chamber is isolated from the outside, and both the fin and the air guide element are connected to the base; and the air guide element and the fin are in communication with the heat dissipation chamber through the base to dissipate heat from the inside of the heat dissipation chamber.

An air moving device includes a housing member, a rotary fan assembly, and a nozzle. The air moving device further includes a light source member mounted within the nozzle. The light source member can be placed within a flow of air moving out the end of the nozzle in a generally columnar pattern. The flow of air can be used to cool the light source member.

A vehicular headlight which, by using a fan, can efficiently cool a light source through a heat sink and also efficiently cool a light source drive circuit. The vehicular headlight includes a lamp housing, a lamp lens, a lamp unit, a fan, and a light source drive circuit. The lamp unit includes a light source, a heat sink, and a light control member. An outlet side of the fan faces the heat sink, and an intake side of the fan faces the light source drive circuit. The vehicular headlight can efficiently cool the light source through the heat sink and also efficiently cool the light source drive circuit.

A photography lamp includes a housing assembly, a heat dissipation assembly, and a light source assembly. The housing assembly includes a lamp barrel and a rear cover, a main air inlet is disposed on the rear cover, and an air outlet grille is disposed on a side wall of the lamp barrel close to the light outlet end. The heat dissipation assembly includes a fan, the air outlet side of the fan is spaced from the light source assembly, a spacing is arranged between the air outlet side of the fan and the light source assembly, and the spacing is always facing the air outlet grille in the direction of the central axis of the lamp barrel. The photography lamp can improve heat dissipation efficiency of photographic lighting fixtures.

An illuminator includes an upper shell, a lower shell, an LED array and at least one fan. The upper shell includes a first outlet portion extending downward and inward from an inlet portion. The inlet portion includes at least one entrance. The first outlet portion includes a row of vents. The lower shell is made of thermally conductive metal and includes primary radiator fins extending from an upper face of a substrate. The lower shell is connected to the upper shell to form a tubular structure. The LED array is connected to a lower face of the lower shell and includes light-emitting diodes. The at least one fan is inserted in the tubular structure, connected to the inlet portion, and aligned with the at least one aperture.
