A lamp comprising an array of solid state lights, using light emitting diodes (LED's) has a massed arrangement of LED lights, the number of which may exceed the capacity of the face area of the lamp, such that a high intensity of light is achieved, being accomodated within the envelope of the lamp by being positioned at an angle from the face of the lamp. In one system embodiment, as a replacement for, and using the form of an incandescent lamp, the LED lights are mounted in substantial coincidence with the shape of the incandescent lamp reflector, to provide an area of light source concentration larger than the projected area of the lamp. In another embodiment for a lamp having a circular face, such as a traffic light, the massed lights are arranged as an annular strip facing inwardly towards the polar axis of the lamp. A conical reflector directs the light outwardly, to provide the required intensity of illumination. More than one such annular light strip may be provided, such as two concentric annuli, with inclined reflectors positioned to direct the light in the desired direction. Semi-reflecting reflectors may be used, to permit the through passage of supplemental light from underlying light sources. These intensified LED lighting systems lend themselves to a wide range of applications.

[ What I claim by Letters Patent of the United States is:] [1.] A lamp for use in illumination having a polar axis of light propagation, and a projected frontal zone of light emission on substantially normal to said polar axis; a mass of solid state lights arranged in close mutual proximity as a strip lamp of predetermined width, the strip lamp being positioned at an angle to the plane of said frontal zone, the face area of said strip lamp exceeding the face area of said frontal zone, wherein said frontal zone cannot accomodate said mass of solid state lights of said strip lamp; said strip lamp providing a light source the intensity of which when energized exceeds the intensity of a Lamp comprising said solid state lights, lying in the plane of, and occupying said frontal zone.
