Özet
In this study, the effects of electrical characteristics on optical characteristics of LED have been investigated. These effects between them have been occured via heat. LED radiant power is proportional with LED current and inverse proportional with junction temperature. Increasing the current of LED causes increasing radiant power and power dissipation of LED. The power-current and instantaneous resistance-current variations have important effect on the radiant power-current optical characteristic.
