The outer covering of the rubber itself can surely make the power cord 9 also have a good waterproof effect.

After the light-emitting diode modules 31 of the light-emitting unit 3 emit light for a period of time, due to the high luminous efficiency of the light-emitting diode chip, considerable thermal energy is bound to be generated. At this time, since at least a part of the heat sink 2 is directly exposed to the outside and is made of aluminum metal having a high heat transfer coefficient, the heat energy can be quickly dissipated to the outside and has an excellent heat dissipation effect.

In summary, a part of the heat sink 2 of the waterproof LED light-emitting diode is exposed to the outside, so that the heat generated by the light-emitting unit 3 can be directly dissipated to the outside, and the heat dissipation effect is good. The waterproof unit 5 can seal the first space 201 and the second space 502, and cooperate with the rubber of the power cord 9 to form a sealed state with a relatively simplified component, thereby generating a good waterproof effect, so that the purpose of the present invention can be achieved. .
