Ultraviolet sterilization module for escalator handrail

Abstract

The invention discloses an ultraviolet sterilization module for an escalator handrail. The ultraviolet sterilization module comprises a ceramic substrate, a titanium layer formed on the side face of the ceramic substrate, a patterned copper layer formed on the surface of the titanium layer, an ultraviolet chip fastened to one side of the patterned copper layer, an upper frame and quartz glass combined to one side of the upper frame. Furthermore, a layer of aluminum substrate (MCPCB) is fixedly arranged on one side of the ceramic substrate, and a heat dissipation structure is additionally arranged on one side of the aluminum substrate. The module also comprises a shell which can cover all the components and can be structurally arranged at one end of an escalator handrail so as to shield ultraviolet light emitted by the ultraviolet light chip and prevent the ultraviolet light from leaking. Therefore, the ultraviolet light chip can be used for continuously emitting ultraviolet light to the escalator handrail to sterilize the escalator handrail.

Description

technical field [0001] The invention relates to an ultraviolet sterilization module for escalator handrails, in particular to a sterilization module for ultraviolet light emitting diodes encapsulated with all-inorganic materials. Background technique [0002] Escalators are usually installed in some public spaces to transport people who come to this space from one place to another. People who come to this space, whether they are walking leisurely, shopping or rushing on their way, will naturally place their hands on the handrails of the escalator when standing on the escalator to maintain personal safety and stability. When all kinds of people put their hands on the handrail, it is easy to leave the bacteria and even viruses on the hand of each person on the handrail of the escalator, and when the next person steps on the escalator, And when the hand is placed on the armrest, it is easy to infect the bacteria and viruses left by the previous person, and then cause physical ...
