One purpose is to smoothly raise and lower a telescopic post used in a floodlight. There is provided a floodlight that includes: a telescopic post that has a plurality of posts whose outer diameters are made gradually smaller, into which the posts can be loosely fitted, and that can be extended and contracted in an up-down direction; a lighting unit attached to the post located on the innermost side; a raising and lowering unit that extends and contracts, in the up-down direction, the posts in conjunction with each other; a base that the post located on the outermost side is fixed to; and dampers that connect a side surface of the post located on the outermost side and a side surface of the post located on the second outermost side.

Floodlight

An object is to provide an LED floodlight that enables efficient use of a cooling means, e.g., a heat dissipation fan, and can pursue a reduction in size. Therefore, it is an LED floodlight wherein a panel-shaped floodlight portion formed as a floodlight surface is formed such that a plurality of LEDs is arranged on a front surface, a heatsink having a plurality of heat dissipation plates on a back surface of the panel-shaped floodlight portion, and a cooling fan configured to send air toward a central portion of the heatsink are arranged in this order, the LED floodlight is formed of an appropriate power supply circuit, wherein a plurality of heat dissipation plates of a heatsink is radially arranged from a central portion to a periphery, a central portion of a coupling surface between heat dissipation plates of the heatsink protrudes toward a cooling fan configured to send air and has a curved surface portion from a central portion to a periphery.
