Abstract
The invention provides lighting apparatuses which are power efficient, environment friendly and long lasting and can be manufactured with high degree of speed, accuracy and flexibility. The lighting apparatuses are easily serviceable and can be produced, transported economically and have higher economical value even on completion of life term of the lighting apparatuses. The present invention reduce the waste of raw material thereby utilizing maximum percentage raw material for produce solid state lighting fixtures using CAD and CNC process and provides retrofitting lighting apparatuses which can be replaced without making considerable changes in existing infrastructure.
