Detailed Description
In order to make the features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail as follows:
fig. 1 is a schematic diagram illustrating the principle of infrared quantum dot photoluminescence according to an embodiment of the invention.
In this example, infrared quantum dots Ag2The solution 11 is deposited on the surface of the substrate 12 by spin coating, ink jet printing, transfer printing, blade coating, pulling, and other preparation methods. The photoluminescence principle of the infrared quantum dots is roughly as follows: the infrared quantum dot light emitting layer 11 obtains energy under irradiation of a high-energy external light source 13 having a shorter wavelength, and electrons in the valence band absorb energy of excitation light photons and transit from the valence band to the conduction band, leaving a hole having a positive charge in the valence band. A portion of the electrons and holes may recombine directly to produce band-edge emission 14, which is the primary light emission mechanism for quantum dot photoluminescence. The excited infrared light acts on the subcutaneous tissues of the human body, thereby providing the infrared physical therapy function for the human body.
In light of the above basic design considerations, the present invention provides a first embodiment, which is illustrated in fig. 2.

Turning on the switch button 22, the LED chip 24 in the bulb begins to emit visible white light for illumination. The layer of infrared quantum dots 25 produces infrared light 26 upon excitation by a white light radiation source. The excited infrared light acts on the subcutaneous tissues of the human body, thereby providing the infrared physical therapy function for the human body.
In the embodiment, the white light LED realizes the illumination function and simultaneously provides the infrared physiotherapy effect for the human body. The intensity of the illumination white light radiation source emitted by the desk lamp can be adjusted as required by changing the magnitude of the voltage signal, and by adjusting the high, medium and low gears in the switch button 22, higher excitation light intensity means that more infrared rays 26 can be excited, so that infrared physiotherapy effect can be generated on deeper subcutaneous tissues. The required target infrared physical therapy subcutaneous tissue depth is further matched by adjusting the intensity of the white light excitation source.
A second embodiment 2 of the present invention is provided with reference to fig. 3.
