Definitions

  • the invention relates to a ceiling lamp, in particular to an embedded lamp fixture.
  • the invention still further relates to a heat sink for a ceiling mounted luminaire.
  • Ceiling luminaires are a common type of lighting fixture that is typically mounted at the mounting holes of a luminaire on a ceiling for indoor lighting. Ceiling luminaires are typically embedded in the ceiling of the house, so this recessed ceiling luminaire is also known as an embedded ceiling luminaire.
  • the illumination device can be divided into two categories: a thermal radiation source and a gas discharge source according to the illumination source.
  • the heat radiation source is a light source generated by the principle of radiation when the object is heated, such as an incandescent lamp, a tungsten halogen lamp, etc.
  • the gas discharge source is a light source generated by the principle of gas discharge, such as: fluorescent lamp, high pressure mercury lamp, high pressure sodium lamp , halogen lamps, etc.
  • the part that generates the most heat is the light source and the driving power source.
  • the heat generated by the light source does not have enough space to dissipate, it will affect the service life of the lamp and even burn out the luminaire.
  • the temperature around the lamp will rise continuously, so we often find that after the lamp is turned on, it is surrounded.
  • the temperature of the environment will begin to rise slowly, and the top of the luminaire may be the roof.
  • the building structure will contain insulation materials. Insulation materials may be laid directly on the ceiling, so they will be directly covered on the luminaire or block the original heat dissipation space, making the heat dissipation of the luminaire more difficult, and it is easier to use after a long period of use.

At present, the luminaire is not prone to failure, and the service life of the luminaire is quite long. Years, it is easy for people to forget to inspect and maintain it. If the lamp is in a superheated environment for a long time, it will rapidly reduce the service life of the lamp, and it may cause structural damage, which may cause harm to people and property.
