Abstract

A hand-carried traffic control light having signaling and flashing functions is disclosed. The above light has a cylindrical handle receiving batteries and a switch cap with a multistage switch. A longitudinal LED carrier that is formed of a PCB and has a plurality of openings is electrically coupled to the switch cap. A plurality of LEDs are mounted to the openings of the LED carrier respectively to be selectively applied with electric power of the batteries in accordance with a switching motion of the switch. A reflector and a flashing bulb are held on the holding protrusion of the LED carrier. The bulb is selectively applied with electric power of the batteries in accordance with the switching motion of the switch. A color reflecting tube surrounds the LED carrier. An external tube surrounds the color reflecting tube. A transparent cap is fitted over a top of the external tube to protect both the reflector and the bulb.

Claims

1. A hand-carried traffic control light comprising:

a cylindrical handle receiving batteries;

a switch cap threaded into said handle, said switch cap having a multistage switch on its outer wall;

a longitudinal LED carrier formed of a printed circuit board and electrically coupled to a connector of said switch cap thereby being connected to said switch, said LED carrier having a plurality of openings;

a circuit unit provided in said LED carrier and connected to both the batteries and the switch;

a plurality of LEDs mounted to said openings of the LED carrier respectively to be electrically connected to said circuit unit thereby being selectively applied with electric power of the batteries in accordance with a switching motion of said switch;

a holding protrusion provided on a top of said LED carrier;

a reflector and a flashing bulb held on said holding protrusion and connected to said circuit unit, said bulb being selectively applied with electric power of the batteries in accordance with the switching motion of the switch;

a color reflecting tube surrounding said LED carrier;

an external tube surrounding said color reflecting tube;

and

a transparent cap fitted over a top of said external tube to protect both the reflector and the bulb.
