Lamp assembly with led stimulation of phospher

A surface mount lamp assembly for mounting to a substrate having a body formed, such as by molding, of a silicone rubber mixed with phosphor. The body has a cavity formed therein for receiving a blue or ultra violet (UV) output light emitting diode (LED), and is typically a translucent combination of silicone rubber and a desired amount of phosphor mixed therein Luminescent output is achieved upon stimulation by short wavelength energy of the diode acting upon the body to function as a frequency converter up-shifting the blue light into longer wavelengths. The silicone rubber/phosphor mixture also acts to mix the blue light with the longer wavelength light to result in a light, typically a white color light, which can be shifted in color hue depending upon the quantity and type of phosphor mixed into the silicone rubber. In one embodiment the body has an enlarged base with a peripheral generally planar lip providing a pick-up surface for vacuum type tools. The base may be generally rectangular in cross-section with opposing sides of the peripheral flattened to provide indexing surfaces for mechanical orientation and handling devices, and include V-shaped cut outs on opposite edges for enabling protrusion of the leads into the slots so formed, thus providing protection for the leads during handling.
