Patent ID: 7563005

Claim:
A light source module for a lamp, comprising: at least two LEDs, each LED including an LED chip capable of producing light in a light emitting direction, a base arranged to secure said LED chip thereon, a lens, and a reflector located adjacent the at least two LEDs, wherein said lens is configured to cause refraction of light from the LED chip at an inner surface of the lens to form a virtual light source image of said light from said LED chip at a certain position behind said base in a direction generally opposite the light emitting direction from said chip, wherein said at least two LEDs are configured such that at least a portion of light emitted from each of the LEDs combines to superimpose at least parts of two virtual light source images each formed by light emitted from two LED chips such that light from the LED chips appears as a light emitted from a single light source, wherein the reflector and the LEDs are configured such that the portion of light combines after being reflected by the reflector, and wherein a distance from said virtual light source image to said lens is substantially the same for each of the LEDs, and the diameter of one lens of said LEDs is different from the diameter of at least one other lens of said LEDs.
