The present invention discloses an optical system comprising: a light source (1); a reflection hood (2); a shielding cone (3) arranged below the reflection hood (2); and a double focus lens (4) arranged between the light source (1) and the shielding cone (3).

A lighting apparatus is provided with a first housing assembly formed from a thermally conductive material and a second housing assembly formed of a thermally conductive material. At least one electrical component is positioned within the first housing assembly and the at least one electrical component is in thermally conductive contact with the first housing assembly. At least one light source is in thermally conductive contact with the second housing assembly. The second housing assembly is not in thermally conductive contact with the first housing assembly, such that thermal energy from the first housing assembly does not directly transfer to the second housing assembly.

A variety of illumination devices are disclosed that are configured to manipulate light provided by one or more light-emitting elements (LEEs). In general, embodiments of the illumination devices feature one or more optical couplers that redirect illumination from the LEEs to a reflector which then directs the light into a range of angles. In some embodiments, the illumination device includes a second reflector that reflects at least some of the light from the first reflector. In certain embodiments, the illumination device includes a light guide that guides light from the collector to the first reflector. The components of the illumination device can be configured to provide illumination devices that can provide a variety of intensity distributions. Such illumination devices can be configured to provide light for particular lighting applications, including office lighting, task lighting, cabinet lighting, garage lighting, wall wash, stack lighting, and downlighting.
