Coastal beacon with cooling function using Peltier element

摘要

The present invention is a base for being fixed to the installation surface; a hollow heat sink installed on the base, a hollow part is provided vertically, and a cooling fin and a contact surface are provided inside the hollow part, respectively; a plurality of metal PCBs fixed along the outer circumference of the hollow heat sink; LEDs provided on each of the metal PCBs and irradiating light to the outside; a Peltier device that is provided to be in close contact with the contact surface of the hollow heat sink and converts thermal energy generated and transmitted from the LED into electrical energy; a cooling fan installed to provide blowing force to the hollow part by operating by electric energy generated from the Peltier element; a condensing lens installed around the LED to collect and emit the light of the LED; and a cover made of a light-transmitting material installed on the upper side of the base so as to cover the hollow heat sink together with the condensing lens. According to the present invention, by allowing the LED to radiate heat by using the blowing power of the cooling fan, the cooling efficiency of the LED can be improved, and the hollow heat sink can be provided with a ventilation passage and heat exchange with the LED efficiently. By doing so, it is possible to achieve smooth cooling of the LED, and it is possible to reduce energy consumption by driving the cooling fan using a Peltier element that generates electric energy using the heat of the LED, and has a structure with excellent assembly provides
