LIGHT EMITTING DEVICE AND ARRAYS THEREOF

摘要

PURPOSE: A light-emitting apparatus with light-emitting diode is to overcome the limitations that most light- emitting light devices have. CONSTITUTION: A housing(11) including light-emitting element(11) and conducting elements(13) are comprised. The conducting elements(13) extend towards an element(11) and serve to capture most of the energy emitted by the element(11). This energy is guided out of the device to the end of the light conducting elements(13) outside the containment(14) where the light energy can be used directly, or by way of a light emission system using fiber optic cable for onward transmission. Each light conducting element(13) is solid and is sealed to the containment(14) at region(16) with axis a directed towards the element(11). The axial length of the light conducting element (13) is at least three times its width transverse the axis. The sealing ensures that a required vacuum state is maintained in the containment(14). Each conducting element(13) sets square and has an end face E near the emitting element(11) to provide for efficient light transfer from emitting element(11) into each conducting element(13).
