The Effect of Surface Mounted Device (SMD) Configuration Array on Light Distribution on LED Lamp

Abstract

Electricity consumption is still dominated by utilization for lighting. Savings and optimization of energy management are obvious to achieve is by the selection of lights that can perform effectively and efficiently, one of them is operating the LED lights. The luminance values of the LED lights are impressed by the configuration of the LED array in the lamp circuit. This research aims to earn the appropriate LED array configuration to achieve the finest light distribution array. Experiments were carried out by assessing 5 LED lamps (Brand A, B, C, D, and custom) on the illumination level from several points to obtain the pattern of light distribution that appears in the work area when there are various configurations. From the assessment proceeds attained that the LED configuration of a circular shape involves a pattern of distribution of light that spread pursuing the work area. The light distribution on the E (Custom) LED lamp is better with a uniform distribution of angles from 0 ° to 180 ° with a rate 189% brighter than with LED D. The greatest illumination point of the five lights takes place at the measurement position at the center or at an angle of 90°.
