e1 lamp leads 18 and 19 provide a means to supply power to led element e1 looking at fig4 thru 6 typical led lamp s1 has lamp lead 18 soldered to conductive top surface 10 and lamp lead 19 soldered to bottom conductive surface 11 of circuit board 9 other led lamps s2 thru s6 are similarly connected so that power supplied to power lead wires 7 and 8 of circuit board 9 is distributed to all of the led lamps this is a parallel circuit arrangement but a series circuit or other arrangements with different quantities of led lamps can obviously be made lamps s1 thru s6 are mounted in a circular formation with their geometric body axises equally angularly spaced and their led elements in a circular pattern diametrically spaced at a distance d1 fig7 is a cross sectional view taken along line 7 39 7 34 in the horizontal plane h of fig2 it shows lamp assembly 20 partially encapsulated in interior light transmitting medium 21 exterior light transmitting medium 1 forms curved exterior surface 4 which when intersected by horizontal plane h forms intersection line 22 which is circular with a radius of curvature c2 and its center of curvature at point 23 line 24 delineates the inside diameter of lighting device 30 it is circular with a radius of curvature c1 and a center.
