Additionally, the projection angle of the modular lens 120 is able to change the properties of the emitted light, for example by changing the wavelength or the intensity of the light, and this can enhance the emission of molecules from the nano-material coating 125 on the optical module. In another embodiment, the nano-material coating 125 is applied or coated onto the normal glass or polycarbonate 115. The LED 130 with the coated glass or polycarbonate 115 emit light at a fixed angle of about 120-degree as illustrated in FIG. 2A of the present invention.

[0045] In one embodiment, the method 300 proceeds to step 310. At step 310, the nanomaterial solution is then sprayed on top of the optical module to provide evenness in coating thickness. This step ensures that the nano-materials are evenly distributed and coated on the surface of the optical module.

[0046] In one embodiment, the optical module is selected from the glass or polycarbonate 1 15 or the lens module 120.

[0047] In one embodiment, the method 300 proceeds to step 315. At step 315, the optical module is placed in a curing chamber at a temperature of 60-80 degrees Celsius.

[0050] In another embodiment, a coated lens module 120 of the lighting sterilization device 100 emit the light source 110 in a customized angle selected from 30 degrees, 90 degrees, and 120 degrees according to the height of the room to enhance emission of the light source 1 10 and provide better propagation of the at least one nano coating material 125.

[0051] In one embodiment, the method 300 proceeds to step 325. At step 325, the method 300 further include the step of electrically arranging the plurality of light-emitting diode (LED) chips on the chip-placing area of the substrate unit.

[0052] In one embodiment, the optical module is a lens module.

[0053] In one embodiment, the lens module is a modular lens.

[0054] In another embodiment, the optical module is a glass or polycarbonate. Fig. 4 is a flow diagram of a concept 400 of application of the lighting sterilization device 100, in accordance with one or more embodiments of the present invention. The method 400 starts at step 405. At step 405, the one or more lighting elements 105 are activated by switching on electricity to provide the light source 110. In use, the light source 110 acts as a propagating medium. The one or more minerals of the nano-material coating 125 propagate and emit following the light wave coming from the light source 110. In use, the optical module is coated with at least one nano-material and the optical module positioned over the at least one lighting element 105.

[0055] In one embodiment, the method 400 proceeds to step 410. At step 410, the nanomaterial coating is supercharged by the light source 1 10. In use, the light source 110 acts as a carrier for nano-material coating wave traveling along with the light source 110. The method 400 proceeds to step 415. At step 415, each molecule of the nano-material coating is supercharged by the light wave received from the light source 110 and becomes energized ion. The method 400 proceeds to step 420. At step 420, the one or more energized ions induce sonorous pulsation in multiple pathogens present in the air and surrounding surfaces with at least one input frequency and causes pathogen inactivation by use of at least one pulsating amplitude of the at least one input frequency shattering airborne & surface pathogens. In use, the nano-material coating 125 is supercharged by the light source 110 and becomes an energized ion and energized nano-material coating is able to zap and shatter pathogen shell & spikes to collapse & rupture within a fraction of milliseconds floating in the air and all the surrounding surfaces. The method 400 proceeds to step 425. At step 425, the pathogens are vaporized in thin air. The test results obtained after application of the present lighting sterilization device 100 using a germicidal LED lamp is able to significantly reduce the bacterial and fungal count in the air over a 24-hour period as illustrated in Table 1 below.

[0056] Table 1 As illustrated in the Table 1 reduction in total bacterial count and total fungal count is observed for 30 minutes, 1 hour, 3 hours, 6 hours and 24 hours exposure time.

[0057] Specifically, the data shows that the total bacterial count is reduced by more than 90% and the total fungal count is reduced by more than 80% after the lighting sterilization device 100 is continuously switched on for 24 hours. It's important to note that the reduction in bacterial and fungal count is very much dependent on the environmental conditions at the time of sampling. Factors such as housekeeping, area cleanliness, air movement, temperature, and humidity can all affect the number of microorganisms present in the air and thus affect the results of the microbial air sampling.

[0058] Accordingly, the present invention provides a lighting sterilization device utilizes visible light within a specific wavelength range of 450nm to 650nm. This specific wavelength range is in the visible light spectrum and is considered safe for human exposure. The present device has a significant sterilization effect by combining the visible light range with the nano-coating material and angle lens which is more efficient, precise and effective at inactivating pathogens.
