A LAMP USING A LIGHT EMITTING DIODE (LED) AS A LIGHT SOURCE

摘要

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.
