Abstract:
An LED lamp including a light guide/light pipe, and a method of reflecting light using same, are disclosed. The LED lamp includes a transparent light pipe enclosed in an envelope, where the light pipe has a lower section and an upper section. The lamp also includes an LED in a recess at a lower end of the lower section, and a reflector formed by an indentation in an upper end of the upper section. The lower section may be a compound parabolic concentrator, and the upper section may be a tapered cylinder. The lower section of the light pipe collects light emitted from the LED, the upper section of the light pipe directs the collected light onto the reflector, and the reflector reflects the directed light in a radial direction.
