A cooling module for illumination device, includes: a substrate contacting a heat-generating illumination part at a lower part thereof and having an insertion groove formed on the upper surface thereof; a heat pipe which radiates the heat generated from the illumination part and includes a horizontal part inserted into the insertion groove and a vertical part vertically bent from the horizontal part and extending in a longitudinal direction; and a heat radiating plate laminated on and coupled to the vertical part of the heat pipe to promote heat radiation of the heat pipe, and including a coupling part coupled to the heat pipe, an inner fin part cut inward from the coupling part and formed to be twisted by a predetermined angle, and an outer fin part cut outward from the coupling part and formed to be twisted by a predetermined angle.

A trellis lighting system that includes at least one lighting and support assembly. The at least one lighting and support may include a cover, a heat sink, and at least one light emitting diode (LED) strip. The cover permits light to pass there through and includes a body extending a first length. The heat sink is configured to couple to the cover and may include a body extending a second length. The body may include an outer surface, an inner surface defining a lumen that extends through the body, a plurality of outer fins coupled to the outer surface, and a plurality of inner fins coupled to the inner surface. The at least one LED strip may be configured to be coupled to the body of the heat sink along the second length thereof so as to dissipate heat generated by the at least one LED strip.

A lighting module includes at least one heatsink configured to dissipate heat generated by a light source, the heatsink including at least a base and a dissipation member, the dissipation member including a series of fins projecting from the base, each fin being defined by a summit that defines the length of that fin, and by two end edges extending between the summit and the base. The lighting module is configured to pivot about two pivot axes, and the series of fins includes eccentric fins the length of which is less than the lengths of the fins at the centre of the dissipation member, at least one fin further having at least one bevel at the junction between the summit and an end edge.

An indirect troffer. Embodiments of the present invention provide a troffer-style fixture that is particularly well-suited for use with solid state light sources, such as LEDs. The troffer comprises a light engine unit that is surrounded on its perimeter by a reflective pan. A back reflector defines a reflective interior surface of the light engine. To facilitate thermal dissipation, a heat sink is disposed proximate to the back reflector. A portion of the heat sink is exposed to the ambient room environment while another portion functions as a mount surface for the light sources that faces the back reflector. One or more light sources disposed along the heat sink mount surface emit light into an interior cavity where it can be mixed and/or shaped prior to emission. In some embodiments, one or more lens plates extend from the heat sink out to the back reflector.

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.
