  • Patent number: 11387703
    Abstract: A method for manufacturing a stator of a waterproof motor includes disposing a first assembly in a mold where the first assembly includes a coil unit wound around an iron core assembly, and filling the mold with a thermosetting plastic which forms a housing after curing. The housing houses the coil unit and the iron core assembly. A recess is formed at one end of the housing. The method further includes disposing a second assembly in the recess of the housing where the second assembly includes a circuit unit, and filling the recess of the housing with a waterproof glue which envelopes the circuit unit after curing. According to the above, the stator of the waterproof motor is formed.

  • Publication number: 20120236566
    Abstract: A lamp includes a heat conducting member, a light-emitting module, a housing and a cooling fan. The heat conducting member has a first face and a second face opposite to the first face. The light-emitting module is coupled with the first face. The housing is coupled with the heat conducting member and has a terminal opening, wherein first and second air-guiding openings are formed between the terminal opening and the heat conducting member. The housing has an inner circumferential wall. An air-flowing room is formed between the inner circumferential wall and the second face. The air-flowing room communicates with the first air-guiding opening and the second air-guiding opening. The cooling fan is disposed at the first or second air-guiding opening and has first and second air-driving openings, wherein the first air-driving opening faces the air-flowing room and the second air-driving opening faces the first or second air-guiding opening.
