An LED that can effectively prevent heat accumulation while preventing short-circuiting, discharge, fire and the like, even in the case where LEDs are relatively densely placed, is provided. In a can type LED (3) where an anode (A) a cathode (K) and an LED pedestal (31p) are provided within a housing (31) and pins (a1) and (k1) of anode (A) and cathode (K) lead out at least to the outside of housing (31) so that a voltage can be applied between anode (A) and cathode (K) via these pins (a1) and (k1), a condition of isolation is maintained between pin (a1) of anode (A) and housing (31), as well as between pin (k1) of cathode (K) and housing (31) , and pin (r1) which is thermally connected to LED pedestal (31p) is provided outside of housing (31). |
