摘要： A color changing television antenna with LED includes a casing, an antenna radiator in the casing, a coaxial cable situated at a rear end of the casing and connected to the antenna radiator. The casing contains an LED lamp, and a transparent display panel extending to the outside from the display panel. The part of the display panel inside the casing has a receiving slot for installing the LED lamp and allowing the LED lamp to project light onto a sidewall of the receiving slot. The display panel transmits the projected light by total reflection. A reflector is installed on a surface of the display panel for reflecting the light transmitted inside the display panel and forming a predetermined pattern. This television antenna can display a specific pattern and improve the display effect based on the principle of total reflection of the transparent display panel.
