The aim of this study was to evaluate the effects of lens type and shape on the light performance from surface mounted device light emitted diode (SMD LED) street light. Another factor considered was the influence of various shapes of the light emitting surface (LES) on the SMD LEDs and size of the SMD LED on light distribution. Besides, the effects of varying correlated colour temperature (CCT) of the LEDs were also investigated. Optical characterization was carried out using the Goniophotometer (GO-2000) and Integrating Sphere (PCE-200A). DIALux Evo software was used to perform the simulation. Road parameters, such as pole distance of 35 m and pole heights of 8 m on a 7 m width road were used. The road requirement was according to the Ten...
