Abstract

This invention provides a healthcare cum optimal illumination device. The inventive device includes at least one frame, at least one light source, and at least one layer of treated filter cover. The light source is disposed in the frame. The light source emits infrared radiation, visible light radiation, and ultraviolet radiation. The visible radiation is used for illumination, and the invisible infrared and ultraviolet radiation is harnessed to improve indoor air quality. The layer of the filter cover is treated with substances of air cleaning properties and encloses the frame. The treated filter cover has at least one opening where air in the frame heated by the infrared radiation flows out from the device and cooler ambient air surrounding the device is drawn through the filter cover into the frame replacing the heated air that has flown out of the device to form air circulation and to perform air purification.

Claims

1. A healthcare cum optimal illumination device comprising:

at least one frame (12);

at least one light source (26) disposed in a cavity of the frame (12), the light source emitting infrared radiation, visible light radiation, and ultraviolet radiation, the visible radiation used for illumination, the invisible infrared radiation and the ultraviolet radiation harnessed to improve indoor air quality; and

at least one layer of filter cover (24), treated with substances of air cleaning properties and enclosing the frame (12), the treated filter cover (24) with at least one opening where air in the frame (12) heated by the infrared radiation flows out from the device and cooler ambient air surrounding the device is drawn through the filter cover (24) into the frame (12) replacing the heated air that has flown out of the device to form air circulation by convection means and to perform air purification.

2. The healthcare cum optimal illumination device according to claim 1, wherein the filter cover (24) has one layer coated with anti-microbial agents, one layer treated with zinc oxide, copper oxide, or calcium hydroxide, one layer coated with activated carbon or zeolite, one layer coated with doped nano-TiO₂, or the combination thereof to capture and remove air pollutants at surfaces of the filter cover (24).

3. The healthcare cum optimal illumination device according to claim 1, further comprising a chassis (20) disposed at the top of the frame (12), with the at least one light source (26) disposed at the chassis (20).

4. The healthcare cum optimal illumination device according to claim 3, further comprising an ionizer (46) disposed at the chassis (20) to improve indoor air quality outside the device.

5. The healthcare cum optimal illumination device according to claim 1, further comprising at least one container (42) containing antimicrobial and fragrant essential oil disposed in the cavity of the frame (12) to disinfect and refresh indoor air outside the healthcare cum optimal illumination device.

6. The healthcare cum optimal illumination device according to claim 1, further comprising a base plate (22) disposed between two frames (12) so that the base plate (22) enables the device to be connectable, scalable, flexible facilitating adds-on and multi-functions.

7. The healthcare cum optimal illumination device according to claim 6, further comprising at least one electric fan (44) disposed at the base plate (22) to enhance air circulation and air filtration.
