Various embodiments relate to a cooling module for cooling a plurality of LEDs that includes a heat sink having a LED side sand a cooling side arranged at opposite sides of the heat sink. The LEDs arranged on the LED side and a first flow channel and second cooling channel are arranged adjacent to each other at the cooling side. The cooling module comprises a first blower and a second blower respectively configured to blow cooling air in a first flow direction through the first flow channel in a second flow direction through the second flow channel, where the first flow direction and the second flow direction being opposite each other. Certain embodiments also related to the light fixture comprising such cooling module and approaches for cooling a plurality of LEDs.

A vehicle lamp is provided. The vehicle lamp includes a base, a first reflection structure, a second reflection structure, a first light emitting structure, a second light emitting structure, and a lens structure. The first reflection structure and second reflection structure are disposed on the base. The first reflection structure includes at least one first focal point and at least one second focal point. The second reflection structure includes a first focal point and a second focal point. The first light emitting structure and the second light emitting structure are disposed on the base. The lens structure includes a lens optical axis and a lens focal point.

A cooling assembly for cooling at least one light source of a light fixture is provided with at least a cooling fan configured to generate a cooling air flow; and at least with a flow-guiding element configured to convey the cooling air flow of the cooling fan and divide it into a primary flow adapted to mainly cool a first zone of the light source and at least a secondary flow adapted to mainly cool a second zone of the light source, at least partially distinct from the first zone.

A light fixture includes a head housing a source assembly configured to emit a light beam and a support assembly configured to support the head. The light fixture further includes a temperature control assembly configured to control the temperature inside the head and/or the support assembly. The temperature control assembly includes at least one temperature control device; at least one first temperature sensor; and at least one first temperature control module housed in the head and/or in the support assembly and regulated by the temperature control device on the basis of data coming from the at least one first temperature sensor. The at least one first temperature control module is provided with a heating element and a ventilating element which are independently controllable by the temperature control device.

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.

The present invention relates to a LED lamp unit (10) comprising at least two LED light sources (2) arranged between a heat sink (3) and an electrical connector base at two opposing sides of the lamp unit (10) to emit in opposed half spaces. The proposed LED lamp unit can be constructed in a very compact form in order to replace known halogen, xenon and incandescent bulbs without changing the construction of the reflector and mechanical parts in a head lamp or signaling lamp.

Light emission module, comprising a housing having at least one first opening and a second opening, a shaping optic, a light emission source, a module with mirrors disposed to receive at least a part of the light rays emitted by the light emission source, and a plurality of mirrors. The light emission module furthermore includes a cooling module configured to generate a flow of fluid circulating inside the inner space between the first and second openings in order to cool the light emission module.

This rotary drive apparatus is arranged to rotate a mirror which reflects incident light coming from a light source, and includes a motor including a rotating portion arranged to rotate about a central axis extending in a vertical direction; a flywheel including the mirror, and rotatably held by the rotating portion; and an impeller directly or indirectly fixed to the rotating portion. The impeller includes a tubular blade support portion arranged to extend along the central axis, and a plurality of blades arranged in a circumferential direction on an outer circumferential surface of the blade support portion. The blade support portion includes an impeller through hole arranged to pass through the blade support portion in an axial direction. The blades are arranged between the light source and the motor. The impeller through hole is arranged to define a light path over which the incident light travels.

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.
