This invention relates to a lamp (80) using a light emitting diode (LED) (30) as a light source. The lamp includes a framework (12), and an LED holder (31) mounted on the framework for holding the LED. A primary reflector (34), having a primary reflecting surface (36) for reflecting at least a portion of light emitted by the LED, is mounted on the framework, being located in a path along which light is emitted by the LED. A secondary reflector (26) is also mounted on the framework, being located relative to the primary reflector such that light reflected by the primary reflector is reflected on to the secondary reflector. The secondary reflector has at least a secondary reflecting surface (28) which is shaped to reflect light reflected thereonto in a forward direction of he lamp and for focusing said light into a substantially focused beam. The invention extends to method of focusing light emitted by and LED.
A method of focusing light emitted by a light emitting diode (LED), the method including reflecting at least a portion of the light emitted by the LED, such that the reflected light radiates away from a focal point, and, after the light has been reflected, focusing at least a portion of the reflected radiated light into a beam by again reflecting the light to direct it into the beam.
A method as claimed in any one of the preceding claims, in which the focusing of the reflected radiated light into the beam is such that the light in the beam is substantially collimated.
A method as claimed in any one of the preceding claims, which includes reflecting a portion of the light emitted by the LED to form a peripheral light zone surrounding the beam.
A method as claimed in any one of the preceding claims, which includes permitting a portion of the light emitted by the LED to be emitted without being reflected, said unreflected portion of the light forming part of the light beam.
A lamp, the lamp having an operatively front end for facing in a forward direction, and the lamp including:
