Abstract
A light source arrangement includes an electric input adapter for electrically connecting with a power source and a light head including a supporting frame and a luminary unit. The supporting frame has a dissipating end and a peripheral surface provided thereon. The luminary unit includes a circuit board provided on the peripheral surface of the supporting frame and electrically connected with the electric input adapter, and at least a luminary element, having two terminal electrodes, which is supported by the supporting frame and electrically connected to the circuit board for emitting light when the terminal electrodes are electrified. Therefore, the heat generated by the luminary element directly dissipates at the dissipating end of the supporting frame so as to prevent the light head from overheating.
