A spotlight comprises a base which is secured by nuts and washers to a support. There may be a single spotlight, or there may be a line of spotlights mounted on a support. Typical examples of use of the spotlight are illuminating displayed products such as jewellery, ceramics, clothes, or cosmetics. The locations may be retail stores, museums, or galleries for example. A main spotlight body is connected to the base by a joint having a bolt in a sleeve allowing rotation of about 180° around the bolt's axis. Further, the base can be secured to the support at any angular position about an axis through the base 2. Light emission is from an LED on a substrate, which is on an aluminium base, which has external threads engaging internal threads of a generally cylindrical casing. A focusing lens is mounted over the LED, and is retained in position by an inwardly-directed lip of the cylindrical casing. |
