Anion-Generating Lighting Apparatus for Heat Dissipation

Solution Overview

Problem

Existing lighting devices with anion generators effectively clean the air but do not address the heat dissipation of LED chips, often requiring complex or heavy heat dissipation structures.

Innovation Solution

A lighting apparatus incorporating a ventilation structure with an anion-generating module, a cylindrical anion-emitting tube, discharge and induction electrodes, and an LED circuit board, where anions emitted through the tube create airflow to dissipate heat from the LED chips without a complicated heat dissipation structure.

AI summary

A lighting apparatus having a heat radiation function by a blowing structure comprising a housing, a cylindrical anion emission pipe, a discharge electrode, an induction electrode, an LED circuit board, and a lighting cover. When anions are emitted from the discharge electrode, air outside the lighting cover is introduced into the cylindrical anion emission pipe via an air through-hole, and then discharged to the outside via a second end of the cylindrical anion emission pipe to be circulated; a space in which the LED circuit board is disposed is in air communication with the air through-hole, such that heat generated by an LED chip on the LED circuit board is emitted. The lighting apparatus may achieve excellent heat radiation function without employing a complicated or heavy heat radiation device.
