Description

Photocatalyst lamp module

technical field

The invention relates to a photocatalyst lamp module in lamps in the field of basic electrical components, in particular to a photocatalyst lamp module (module, photocatalyst with ultraviolet) that can greatly increase photocatalyst reaction efficiency, avoid waste of photocatalyst materials, and has the effect of convenient assembly lamp module).

Background technique

The so-called "photocatalyst reaction" is a photochemical reaction that uses titanium dioxide photo-semiconductor to convert light energy into chemical energy. This reaction is similar to the photosynthesis of plants, which can decompose water or oxygen into radicals, such as O, O2, OH-etc. During the oil crisis, the photocatalyst reaction was used to obtain clean hydrogen energy, but it was not able to expand its utilization because of the inability to solve the problem of its reaction efficiency. The reaction rate of the photocatalyst reaction is related to the number of photons received by the surface of the photocatalyst and the number of reactant molecules present on the surface of the photocatalyst. In the current research, the effect of titanium dioxide as the photocatalyst is the best. When the particle size of titanium dioxide is ground to less than 0.1 μm (about 1/10 of the general pigment titanium dioxide), it can reduce light scattering, improve transparency and greatly increase the absorption of ultraviolet rays. Therefore, even under very weak light, the photocatalyst can effectively react, and the light with a wavelength between 300nm and 400nm is most suitable as the excitation light for titanium oxide. In the white fluorescent lamp, the amount of ultraviolet light with a wavelength below 380nm is only 1/30, while in the red light, the excitation light that can be used as titanium oxide is only 1/40. The light quanta captured by the photocatalyst under such indoor luminosity can react , It can effectively remove low-concentration harmful substances, bacteria, oil, smoke, etc. It is worth noting that at present, nanometer (nimi) grade titanium dioxide materials have been successfully applied in photocatalyst coatings, photocatalyst solutions, photocatalyst lamp tubes, photocatalyst masks, photocatalyst air conditioners, and photocatalyst electric fans.

In the above-mentioned photochemical reaction, positively and negatively charged holes and electrons will be generated, which will generate hydroxyl radicals after catalytic reaction with water vapor or oxygen in the air. It will decompose organic matters such as bacteria, oil stains and planktonic bacteria in the air on the surface of the ultraviolet light tube 100, and convert these organic matters into harmless inorganic substances, thereby achieving the functions of sterilization, bacteriostasis and deodorization.
