Abstract
A traffic police baton, comprising a light transmitting cylinder which has a corrugated inner wall covered with a layer of light dispersive film, a circuit board assembly fastened in said light transmitting cylinder which has a plurality of high light intensity of light emitting diodes connected together and longitudinally aligned, and a control circuit to control saidd high light intensity of light emitting diodes to flash in sequence according to predetermined setting.
Claims2
For conducting the traffic, a traffic police baton comprising:
- a light transmitting cylinder having two opening at two opposite ends and a corrugated surface portion over the inner wall thereof;
- a light dispersing film covering over said corrugated surface portion;
- a lamp set fastened in said light transmitting cylinder at one end by a rim;
- a handle comprised of two opposed shells connected into a cylindrical structure for holding said light transmitting cylinder, having a plurality of blocks raised from the outer wall surface thereof;
- a bottom cap attached to said handle at the end opposite to said light transmitting cylinder, having a plurality of projecting strips transversely projecting inwards from the top edge thereof defining therebetween a plurality of notches through which said blocks on said handle are inserted and rotated to respectively engage with said projecting strips;
- a circuit board assembly in an elongated shape having one end inserted inside said handle and an opposite end inserted in said light transmitting cylinder, a plurality of holes longitudinally aligned, a plurality of high light intensity of light emitting diodes respectively fastened in said holes at one end and longitudinally disposed in same direction, a plurality of reflectors respectively fastened in said holes at an opposite end to reflect the light from said high light intensity of light emitting diodes to said light dispersing film, a power supply unit fastened in said handle, a power switch for connecting said power supply unit to said lamp set and said high light intensity of light emitting diodes, a selector switch comprised of a spring and a key for controlling the flash mode of said high light intensity of light emitting diodes.
