Problems solved by technology

[0003] The effect of ultraviolet light sterilization is related to the irradiance of ultraviolet light, the irradiation time and the condition of the object to be sterilized. Improving the irradiance of ultraviolet light and the irradiation time can certainly improve the sterilization effect, but the distribution of irradiance is uneven and the irradiation time is too long Neither designers nor users would like to see

Abstract

In an embodiment, a sterilization apparatus, adapted to sterilize a liquid to be sterilized, comprises a first sterilization light source, a first container and a sterilization container. The first sterilization light source includes a carrier, a plurality of LED packages and a plurality of collimating units, wherein the plurality of LED packages are disposed on and electrically connected to the plurality of carriers, and each of the plurality of collimating units separately is disposed on a corresponding LED package. The first container accommodates the first sterilization light source, and defines a first light-mixing space. The sterilization container includes an accommodating space for accommodating the liquid, wherein the first container is assembled together with the sterilization container, and the first light-mixing space is disposed between the first sterilization light source and the accommodating space.

Description

technical field [0001] The invention relates to a sterilizing device, in particular to a sterilizing device using a light emitting diode as a sterilizing light source. Background technique [0002] Ultraviolet light was discovered in 1801. Since 1877, British scientists have confirmed the bactericidal ability of ultraviolet light to kill Bacillus subtilis and buds by ultraviolet light irradiation. The deep ultraviolet light with a wavelength between 200nm and 280nm can directly destroy the bonds between deoxyribonucleic acid (DNA) and oxygen ribonucleic acid (RNA) in bacteria and viruses. % to 99.9%. Among them, ultraviolet light with a wavelength between 250 nanometers and 270 nanometers has the strongest bactericidal effect. [0003] The effect of ultraviolet light sterilization is related to the irradiance of ultraviolet light, the irradiation time and the condition of the object to be sterilized. Improving the irradiance of ultraviolet light and the irradiation time ca...
