Abstract
A light emitting diode (LED) down lamp with a replaceable color temperature filter uses a plurality of blue LEDs as a light source and includes a color temperature filter and a fixing ring. The color temperature filter is installed across the top of the down lamp to apart cover the LEDs with a distance, and then fixed by the fixing ring. Therefore, the color temperature filter can be replaced flexibly with other one in different color temperature one by removing or assembling the fixing ring to change the light projected from the LEDs into different color tone for fitting studio, stage or indoor space applications. Such lamp achieves the effects of enhancing the illumination function of a single down lamp, reducing the inventory cost and improving the practicality.
