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.

An adjustable LED lighting system may allow for a variable frequency outputs during different time periods and/or in response to specific use commands. The LED lighting system may include one or more target frequencies for one or more target time periods. The LED lighting system may store the target frequencies and target time periods and make the frequency modifications at the user-specified times.

A light system includes a main body defining an internal chamber and a lighting assembly secured to the main body, wherein the lighting assembly comprises at least one light unit configured to emit light. The light system further includes a fan configured to generate an airflow and an airflow circuit configured to direct the airflow out of the main body of the lighting assembly. The light system also includes a tilt detection unit configured to detect a tilt angle of the lighting assembly and to generate a control signal to cause a speed of the airflow generated by the fan to change based at least on a detected change in the tilt angle of the lighting assembly.

Provided is an air-cooled LED light having an LED substrate with an LED mounted thereon, and a casing with the LED substrate mounted thereon, the casing including: an inlet port through which air flows in; an outlet port through which the air fed from the inlet port is discharged; an separation plate that is interposed between the inlet port and the outlet port to divide an inner space of the casing; an opening that is formed in the separation plate; and a fan that is disposed on the separation plate in line with the opening of the separation plate. It is possible to prevent the air filled in the lower portion of the separation plate from flowing backward to an upper portion of the separation plate thereby to improve the cooling efficiency.

An LED lamp includes a mounting seat, a circuit board mounted in the mounting seat, a plurality of primary LED lights mounted on the circuit board, a light permeable frame mounted on the mounting seat, and a shade mounted on the light permeable frame. The mounting seat is provided with a light guide face corresponding to an inner peripheral face of the light permeable frame. The light rays of the primary LED lights permeate through the shade and irradiate downward in a perpendicular manner, and are guided by the light guide face of the mounting seat, pass through the light permeable frame and are diffused and emitted sideward from the shade in an angle of one hundred and eighty degrees (180) to expand the illuminating angle and range of the primary LED lights.

An illumination apparatus includes a solid state light source unit including a plurality of light emitting points that emits light and is arranged on a light emitting face, a plurality of optical elements configured to guide light emitted from the plurality of light emitting points to an illumination target face, a heat conduction member arranged in a space different from a space between the light emitting face of the solid state light source unit and the plurality of optical elements, configured to conduct heat from the solid state light source unit, and a cooling unit configured to supply a first fluid to the heat conduction member along a first flow path and supply a second fluid to the space between the light emitting face and the optical elements along a second flow path, wherein the second fluid is a fluid from which dust or dust and moisture is reduced.

Described is dynamic control of the temperature of the envelope of an HID lamp in order to stabilize the output color temperature of the lamp. As the lamp power is changed, or environmental factors alter the lamp envelope temperature, the system senses these changes and adjusts the lamp cooling systems so as to move the lamp envelope temperature back to the desired point.

The disclosure relates to the technical field of stage lighting fixtures, and in particular to a stage lighting fixture thermal system capable of dynamically adjusting air flow delivery. The stage lighting fixture thermal system capable of dynamically adjusting air flow delivery comprises a light source and a heat dissipation chamber; the light source is arranged inside the heat dissipation chamber; an illuminating side of the light source faces a light outlet on a top part of the heat dissipation chamber; wherein the stage lighting fixture thermal system further comprises at least one first air supply mechanism communicated with the heat dissipation chamber, and the first air supply mechanism is dynamically arranged on the heat dissipation chamber. The stage lighting fixture thermal system of disclosure is simple in structure and convenient to use, and may adjust, according to the change of position of the light source, the air supply mechanism to an optimal position for heat dissipation, so that the life of the light source is prolonged.
