Modularization heat dissipation built -up member and including illuminator and down lamp of this built -up member

The utility model provides a modularization heat dissipation built -up member and including illuminator and down lamp of this built -up member. The utility model discloses a modularization heat dissipation built -up member (2) of lighting equipment (100), it includes base (22), the base (220 include first figure arrange that (23) are in order to be used for the thermal coupling to arrive lighting equipment's light source (31), and heat -conduction component (21) of second figure, heat -conduction component (21) via arranging that (23) are associated to base (22), and the second figure is less than or equal to first figure for the thermal load of lighting equipment's predetermine is matchd to the heat capacity of modularization heat dissipation built -up member. In in the aspect of one, the configuration that chimney effect was maintain to use module heat -transmission dissipation built -up member has been provided. Illuminator and down lamp including such heat dissipation built -up member have still been prov
