A thermal management system for led luminaires that, in certain embodiments, includes a heat sink, a heat-dissipating pipe, a base plate, a variable speed air-cooling element, an air-directing structure, a temperature measuring element, and a driver that includes at least one of thermal sensing response logic, light-emitting dimming control logic, fan speed control logic and air-cooling element malfunction detection logic. In some instances, the heat sink includes a plurality of fins coupled to a base plate. In some instances, one or more heat-dissipating pipes extend partially inserted along the length of the base plate and outwardly away from an end of the base plate. In some embodiments, an LED PCB assembly is coupled to the base plate. In some embodiments, fan speed variability, LED dimming, or both are engaged in combination with heat transfer and dissipation associated with the heat sink and the one or more heat-dissipating pipes.

In a device a crop is cultivated in an at least substantially daylight-free environment, wherein the crop is exposed in an at least substantially fully conditioned cultivation space (10) to actinic artificial light from an array of artificial light sources (30) present in the cultivation space. During a cultivation cycle a power output of the artificial light sources (30) is adapted to an energy absorption of a part of the crop (50) illuminated thereby such that the crop close to each of the array of artificial light sources is subject to an at least substantially constant and at least substantially mutually equal vapour deficit.

The present invention is related to an UV LED curing apparatus, and more particularly, to an UV LED curing apparatus with improved housing and switch controller. The light reflective inner casing is preferably provided as an effective UV light reflector and as a supporting substrate of the UV LED light source while being capable of transmitting heat from the UV LED light source away for further heat dissipation to the ambient by the outer casing. The outer casing is detachably attached to the inner casing and allows a greater user interaction for decorative and entertainment purposes while also being a protective and heat dissipation means.

The invention relates to lightweight LED lighting systems for permanent and semi-permanent mounting on elevated structures, the lighting systems having integrated support and thermal transfer features. The systems are particularly suited for elevated mast systems and specifically for mast systems that are repeatedly lifted and lowered such as drilling and service rig masts. Specifically, the invention improves a) the weight/lumen ratios of LED lamp assemblies and LED lighting systems, b) the net added weight of LED lighting systems, c) the footprint of LED light systems and/or d) obviates the need for removing LED lighting systems or their sub-assemblies when transporting mast systems.
