It's one of many shorthand names for "Jesus"
https://en.wikipedia.org/wiki/Christogram
In the Latin-speaking Christianity of medieval Western Europe (and so among Catholics and many Protestants today), the most common Christogram became "IHS" or "IHC", denoting the first three letters of the Greek name of Jesus, ΙΗΣΟΥΣ, iota-eta-sigma, or ΙΗΣ.
The Greek letter iota is represented by I, and the eta by H, while the Greek letter sigma is either in its lunate form, represented by C, or its final form, represented by S. Because the Latin-alphabet letters I and J were not systematically distinguished until the 17th century, "JHS" and "JHC" are equivalent to "IHS" and "IHC".
