Systems and methods for a high output, high color quality light are disclosed. In some embodiments, such a light may include a light fixture including one or more LEDs configured to output a cumulative light output; wherein the cumulative light output comprises an intensity of greater than or equal to 10,000 lumens; and wherein the cumulative light output comprises a CRI of at least 90.

A horticulture grow light includes: an emitter array; a heatsink on one side of the emitter array; a driver electrically connected to the emitter array; and an electrically isolating baffle connected to the heatsink. The baffle includes: an air funnel; a plurality of driver panels respectively connected at opposite sides of the air funnel and extending toward the heatsink; and a plurality of support panels respectively connected to the driver panels and extending toward the heatsink. A first active airflow section is formed between inner surfaces of the driver panels and inner surfaces of the support panels, and second active airflow sections are respectively formed on either side of the first active airflow section and between the inner surfaces of the driver panels and outer surfaces of the support panels.

A light fixture for an indoor growing facility is provided. The light fixture includes a housing, a lighting module, and a heat sink. The housing defines a first portion and a second portion. The lighting module is at least partially disposed in the second portion. The heat sink overlies the lighting module and is configured to dissipate heat away from the lighting module.

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.

The T-bar includes an elongate rigid spine extending between terminal ends including either a fixed anchor or adjustable anchor for attachment to adjacent T-bars or other supports. An upper heat sink is provided on an upper portion of the spine to enhance heat transfer from the T-bar to air surrounding upper portions of the T-bar. A light housing is provided on a lower portion of the T-bar which is configured to support a lighting module therein, such as a light emitting diode (LED) light. A lower heat sink is provided above this light housing and integrated into a rest shelf which supports ceiling tiles adjacent the T-bar. A power supply is provided which can be removably attached to the T-bar and provide appropriately conditioned power for the lighting module.

Sealed LED lighting fixtures operated under certain conditions (e.g., outdoors, in cold ambient environments, at high operating current, and/or in non-hermetic environments) will oftentimes exhibit condensation on an inner surface of the emitting face of the fixture. When occurring, said condensation impairs the ability to produce useful light – namely, light harnessed and directed in a manner so to provide lighting for a task (or otherwise desired) – by diffusing light emitted from the lighting fixture. Envisioned are apparatus, methods, and systems to reduce moisture in sealed LED lighting fixtures so to reduce or eliminate condensation, and in a manner that addresses both fixtures already in the field and those being assembled in a factory setting. In one form, a carrier embedded with desiccant is positionally mounted inside the fixture in a desired position which has no or minimal impact on light output from the fixture.

A lighting device configured for controlling a light radiation direction thereof, may include a housing provided with a light source; a lens unit provided in the housing, the lens unit being configured to concentrate the light generated from the light source; a length-variable unit mounted to the housing, the length-variable unit being configured so that a length thereof is changed, in a response to application of electricity thereto, in a direction in which the position of the lens unit is changed; and a controller configured to control a light radiation direction of the lens unit by setting a voltage of the electricity to be applied to the length-variable unit so that a length of the length-variable unit is changed according to a set voltage and the position of the lens unit is changed according to a change in the length of the length-variable unit.

Implementations are described herein for an adjustable recessed lighting apparatus (100) with a rotation ring (110). In various embodiments, a base (101) may be mounted to a surface and includes a light passage that generally directs light in a first direction (FD). The rotation ring (110) may be rotatably mounted to the base (101) such that the rotation ring (110) is rotatable about the light passage. At least one light source (140) may be mounted within the apparatus (100) to emit light through the light passage in a second direction (SD). A first drive (112) and a second drive (114) may be fixedly secured to the rotation ring (110). Accordingly, when torque is applied to the first drive (112), the rotation ring (110) may rotate relative to the base (101) about the light passage.

A lighting fixture is provided. The lighting fixture includes a lamp body, a light source component and an optical element; the lamp body and the optical element form a closed cavity, the light source component is accommodated in the closed cavity; the light source component includes a light source substrate and a light emitting unit located on a front surface of the light source substrate, and the optical element is located in a light emission direction of the light emitting unit; the light source substrate includes a back surface facing away from the front surface, the lamp body is formed with a heat dissipation structure, and the heat dissipation structure is in contact with the back surface of the light source substrate. The lighting fixture provided by the present disclosure has good heat dissipation performance.

A cooling device includes: a casing including an air intake port and an air exhaust port; a single heat releaser including a plurality of fins arranged in a gas flow path from the air intake port to the air exhaust port; a first heat diffuser arranged in the casing, connected to a first heat generation body generating heat at time of driving and the single heat releaser in a heat-transferable manner, and arranged at a position forming a part of the gas flow path passing through a space between the plurality of fins; and a second heat diffuser arranged in the casing, connected to a second heat generation body generating heat at time of driving and the single heat releaser in a heat-transferable manner, and arranged at a position forming a part of the gas flow path passing through the space between the plurality of fins.
