1. A method of making a photo-radiation source comprising the steps of:

  • providing a first planar conductor;

    disposing a formation of light emitting chips on the first planar conductor, each chip having a cathode and an anode, one of the cathode and anode of each chip being in contact with the first planar conductor;

    disposing a second planar conductor on top formation of light emitting chips so that the second planar conductor is in contact with the other of the cathode and anode of each chip;

    binding the first planar conductor to the second planar conductor to permanently maintain the formation of light emitting chips without the use of solder or wiring bonding for making an electrical and mechanical contact between the chips and either of the first planar conductor and the second planar conductor.
