Meaning Of These Symbols

electronics symbol

I got an email that asked about the meaning of the symbols in the yellow box. It was a LED control gear that was made in China. I could not locate the meaning of these symbols. Do you know of any source for the meaning of these symbols?

    -The first one means that it is fire proof, it can be use over a flamable surface.
    -The second means a termal protection reaching 80ºC generaly in a hot spot on the surface.
    -The third means a Independent controlgear, not built in or integrated in a luminaire.
    -The fourth is a convination of 2 symbols of IEC 60417, one safety isolating controlgear and the other it`s for short-circuit proof controlgear (inherently or non-inherently)
    -The fifth is Class II equipment or double insulated

    It all come from the standar IEC 61347-2-13 for d.c or a.c supplied electronic controlgear for LED modules

    It was answered late but it could help other people perhaps
