[0030] Specifically, see Figure 1The projector assembly 3 is located at a relatively central position in the lower cover 2. The heat emitted from the outer surface of the body 31 of the projector assembly 3 is dissipated through the first heat dissipation shell 32 and the second heat dissipation shell 33.
