Definitions

  • the present invention generally relates to a lamp and, more particularly, to a lamp that is inserted into a ceiling for indoor or outdoor illumination.
  • Taiwan Patent Publication No. M359644 discloses a lamp cooling apparatus comprising a base plate, an annual cooling seat, a fan and a housing.
  • the base plate has a first face and a second face.
  • the first face is mounted with a plurality of light-radiating elements and the second face is coupled with the annual cooling seat, with a plurality of vents extending from the first face to the second face.
  • the fan is disposed on the annual cooling seat.
  • the housing is coupled to the second face of the base plate in order for the annual cooling seat and the fan to be covered in the housing, wherein the first face that is mounted with the light-radiating elements faces outward.
  • the housing has a plurality of striped vents which allows external air to be drawn into the housing therethrough during rotation of the fan. The drawn-in air flows through the annual cooling seat for air exchange with the hot air generated by the light-radiating elements, and is then drawn out of the lamp via the vents of the base plate.
  • An embedded lamp refers to a lamp that is inserted into a "plate ceiling" (that is, the ceiling that is assembled by a plurality of square plates) by inserting its housing into the ceiling so that the first face of the base plate mounted with the light-radiating elements faces downward for light radiation.
  • a plate ceiling that is, the ceiling that is assembled by a plurality of square plates
  • vents of the housing are located above the plate ceiling.
  • the area above the plate ceiling is an enclosed space with poor air circulation, therefore resulting in poor heat dissipation.
  • objects such as pipelines, cable lines or heat shield articles may be disposed in the enclosed area. Therefore, air circulation is further impacted.
  • the conventional lamp has poor heat dissipation due to the structure design thereof, leading to a difficulty in dispelling the heat remained on the annual cooling seat.
  • the service life of the lamp is reduced as the light-radiating elements are long operated under a high temperature condition.

  • the direction of air flow may be changed by switching the rotation directions of the fan 3. For example, when the fan 3 rotates in a clockwise direction, the external air is drawn into the second compartment 21 via the ventilation opening B, air channel A and through-hole 24, and then drawn out of the lamp via the vents 251.
  • the ventilation opening B and the vents 251 are allowed to communicate with the external air because the ventilation opening B and the vents 251 are both located beneath the ceiling 9 rather than above the ceiling 9.
  • the air inside the lamp is allowed to smoothly circulate with the external air.
