A sterilizing photo catalyst device of air conditioner, wherein one or more ultraviolet (UV) light-emitting diodes (LEDs) are installed at the passageway mouth, the intake, or the outlet of an air conditioner. The UV LEDs can thus be placed at one side of a filter net and a photo catalyst attached together to save a holder for supporting the photo catalyst net, hence simplifying the whole structure. Simultaneously, the UV LEDs are connected in parallel. When one of the UV LEDs malfunctions, the rest of UV LEDs still can work and partly function properly. Moreover, because no ICs are required in the whole circuit, the cost is lower. |
