A light assembly for attachment to a surface of a vehicle. The light assembly includes a vehicle base configured to be coupled to the surface of the vehicle and a light head coupled to the vehicle base. The light head is configured to rotate relative to the vehicle base about a first axis and about a second axis that is different from the first axis. The light head is configured to rotate about the first and second axes at a first speed in response to a first user input, and to rotate about the first and second axes at a second speed that is different from the first speed in response to a second user input.

An LED illumination apparatus includes an LED device; a base having a concavity for receiving the LED device; a heat sink including a plate coupled to the base and a plurality of fins extending from a surface of the plate opposite the base, the fins extending laterally beyond sides of the plate; a cooling fan for forcing air over the fins; and a casing housing the LED substrate, the base, the heat sink, and the cooling fan.

An optical system and luminaire are provided. The optical system includes first and second lighting effect assemblies. Each lighting effect assemblies include an effect selector and a lighting effect insert rotatably coupled thereto. Each effect selector positions its lighting effect insert in a light beam. The lighting effect inserts include a prism with a rear surface and a front side having a first plurality of facets. The rear surface has a plurality of regions aligned with corresponding facets. The regions are color filters. Some lighting effect inserts are an effects plate and a prism, where the effects plate has color filter regions. The effects plate and the prism may be separately rotatable at desired speeds and/or directions. Some lighting effect inserts are a prism with color filter regions on the facets.

A lens casing in an LED illumination apparatus hermetically housing LED elements is cooled. The LED illumination apparatus includes a tubular lens casing, an LED holding part mounting the LED elements thereon, and a base part to which the lens casing is coupled. The base part has a concave part for housing the LED holding part, and the lens casing is coupled to the base part, thereby hermetically sealing the internal space of the lens casing. The base part has support columns protruding into a space outside the LED illumination apparatus and supporting a fan device. The fan device makes taken-in air collide with the base part and exhausts the air through the window parts each formed by adjacent support columns and the side of the frame of the fan device and the side of the base part that face each other as upper and lower frames thereof.

A working light includes a frame and a plurality of LED modules located in the frame. Two supporting plates at two ends of the frame are respectively combined with two ratchets. Two ends of the LED modules are combined with ratchet plates. The ratchets are respectively assembled to the ratchet plates to control a rotation angle of the LED modules. The working lights can be stacked with each other in one or more directions. The ratchets are at the side portions of the LED module. Therefore, after the LED module is assembled in the frame of the working light, the ratchets allow the LED module to be rotatable within 180 degrees. Hence, the LED module can be rotated, so that the illumination angle of the LED module is adjustable.

A lighting apparatus has an upper hub, a base, a lower hub, and a plurality of illumination devices that are pivotably supported at the upper hub, with each illumination device being pivotable up and down towards each other, as well as being rotatable. A shaft assembly has an upper end that is secured to the upper hub, and a lower end that is secured to the base. A plurality of legs is connected to the lower hub and the base for pivoting motion therebetween.
