Air purification illuminating device

The invention discloses an air purification illuminating device comprising an illuminating device, an air purification device and an anion generating device. The illuminating device comprises an installation box, an LED light source plate, and a mask. The LED light source plate is installed at the upper end face of the installation box, and the mask is covered on the LED light source plate, thereby forming a lamp body. The air purification device and the anion generating device are installed inside the installation box. Therefore, the structure is ingeniously designed, the size of the product can be reduced, and the cost is saved. Being provided with both the illumination function and the air purification function, the air purification illuminating device can effectively degrade poisonous and harmful gases in the air, kill a variety of bacteria, purify the air, increase the indoor environment quality, and can further generate negative oxygen ions which are beneficial to body health and are scavengers in blood veins. The practicality of the illuminating device is enhanced by integrating the three functions within one product. The mask is a diamond-shaped crystal mask which can reflect and diffract the light source by certain angles, with the lighting effect being balanced, and without dark zones.
