It is a trend to use LED lamps which have high efficiency and long life time to save the consumption of electricity. LED’s are used already not only in automotive, TV, road and highway lighting but in many household as lighting lamps. One problem of LED lamps is generation of heat which causes decline of efficiency. In this study heats generated from two different commercial LED desk lamps depending on lighting time and effects on brightness was analysed. The brightness levels of lamps were measured in a dark room. The temperature, brightness, and electricity of each lamp were measured every 30 minutes. Lux per used electricity was calculated and compared. By the experiment we could determine that temperature of lamp rise and brightness falling with time. In this work two experiments are done to improve this characteristics of LED stand lamp.
