A street light allows an electronic device installed therein to work properly. The street light has an internal chimney structure for dissipating heat from the electronic device and preventing any liquid from flowing into a space where the electronic device is accommodated. This allows the street light to internally provide both a dry environment and a heat dissipation mechanism for the electronic device, without closing an internal space of the street light, so as to greatly improve the above undesirable structural drawbacks of the conventional street light.

LED related lighting methods and apparatus are described. Various features relate to water tight light fixtures. Some of the fixtures are spotlights while other fixture are intended for in ground use. The light fixtures in at least some embodiments include power control features. In spotlight embodiments beam angle and power or light output can be controlled without opening the light assembly or compromising the water tight seals which also protect against dirt. In ground embodiments support tilt angle setting which allow a user to set the light fixture to one or more tilt angles. Beam angle can also be changed in some embodiments as well as power control. Beam angle, power control and tilt angle adjustments are supported in some embodiments but need not be supported in all embodiments with some embodiments using one or more of the described features but not all features.

A light emitting apparatus includes a light source, a unitary formed heat sink with a plurality of heat dissipating fins, a lensed enclosure that retains a light source and at least one power consuming device other than the light source. The lensed enclosure includes a recessed opening having at least a first wall that terminates at a substantially perpendicular second wall. The plurality of heat dissipating fins are disposed on at least one adjacent exterior side of the walled enclosure, the fins extending outwardly. At least one fin coupled to the heat sink extends beyond the light source, and the heat generated by the light source travels by conduction laterally through the heat sink to the at least one coupled fin.

A luminaire is provided, having first and second enclosures, a pipe, and a chamber. The first enclosure includes luminaire components that emit a light beam, has two openings, and is otherwise sealed. The second enclosure includes electronic circuits coupled to the luminaire components, has an opening, and is otherwise sealed. The first enclosure rotates relative to the second enclosure. The pipe couples an opening of the first enclosure to an opening of the second enclosure, rotates relative to the first enclosure, and is otherwise sealed. The chamber includes a drying agent, two openings, and is otherwise sealed from the external air. One opening of the chamber is rotatably coupled to an opening of the first enclosure. The other opening of the chamber is completely covered by a membrane that allows air to pass through the material while reducing the passage of water droplets in the air.

A luminaire, including a shade, a mounting base, a first end cap, a second end cap, a light source module and a drive power source. The shade has two first folded edges opposite to each other, and the mounting base has two second folded edges opposite to each other; the first folded edges are in snap-fit with the second folded edges; the luminaire further includes a shade pushing assembly, and the shade pushing assembly includes a force-exerting key and a pushing piece; one end of the force-exerting key is connected to the pushing piece, and the other end of the force-exerting key extends out of the mounting base; the pushing piece abuts against a first end face of at least one of the first folded edges.
