Abstract
The invention relates to the technical field of sensors, in particular to a patch type ultraviolet sensor. The patch type ultraviolet sensor comprises a seat body, an esd electrostatic protection Zener tube, an ultraviolet chip, a positive electrode bonding pad and a negative electrode bonding pad, a mounting cavity is formed in one end of the seat body, and the positive electrode bonding pad andthe negative electrode bonding pad which are distributed at intervals are attached and fixed to the bottom of the mounting cavity; an esd electrostatic protection Zener tube and the ultraviolet chip are arranged in the mounting cavity, the positive electrodes and the negative electrodes of the esd electrostatic protection Zener tube and the ultraviolet chip are correspondingly welded to a positiveelectrode bonding pad and a negative electrode bonding pad which are located in the mounting cavity respectively, and the other end of the seat body is fixedly provided with the positive electrode bonding pad and the negative electrode bonding pad which are distributed at intervals in an attached mode. The positive electrode bonding pads and the negative electrode bonding pads at the two ends ofthe base body correspond to each other, the two positive electrode bonding pads and the two negative electrode bonding pads are correspondingly connected and conducted respectively, and a lens is installed on the open side of the mounting cavity. The patch type ultraviolet sensor has the advantages of simple production process, good heat dissipation performance and relatively stable overall performance.
