Description

Technical Field

[0001] This utility model relates to the field of air purification lamp technology, and in particular to a negative ion air purification lamp. Background Technology

[0002] Negative ion air purifying lamps are innovative products that integrate lighting and air purification. Their main purpose is to eliminate harmful gases, smoke, viruses, bacteria, and odors in indoor air, while also promoting metabolism, enhancing immunity, and relieving fatigue. This device uses advanced plasma technology, generating free electrons through the discharge of carbon fibers at a negative high-voltage end. These electrons combine with oxygen molecules in the air to generate negative ions. These negative ions actively capture harmful substances in the air, such as benzene, toluene, formaldehyde, and other harmful gases produced during renovations, as well as smoke, fumes, viruses, and bacteria, thus purifying the air.

[0003] However, current negative ion air purifying lamps on the market have a significant design flaw: the negative ion generator is usually installed inside the lamp housing. While this design achieves compactness and aesthetics, it makes repair difficult if the negative ion generator malfunctions. Due to the limitations of the lamp housing, repair personnel have limited direct access to the negative ion generator, increasing the difficulty and cost of repairs. Utility Model Content
