Abstract
This paper gives a comparative analysis on the luminous efficiency of the bulb type LED lamps. we compare and analyze the measurement values bulb type LED lamps using both photogoniometer and integrating sphere. The volt and watt of one 1map are 220 V and 7 W, respectively. The volt and watt of other one are 100 V and 5.3 W, respectively. the values of those were 79.7 1m/W and 76.9 1m/W in the integrating sphere, respectively. Similarly, the values of those were 80.2 1m/W and 79.3 1m/W on the photogoniometer, respectively. As a result, the value of luminous efficiency can be measured using either integrating sphere or absolute goniometer regardless of the difference in case of bulb type LED lamps.
