Described radiator is to be used to the integral type metal heat sink that supports and dispel the heat; Fin comprises top, inner side edge, bottom and outer side edges, and fin is up-narrow and down-wide, and inner side edge is vertical with bottom and upper segment, and outer side edges is hypotenuse and/or circular arc limit.Radiator material is aluminium, copper or other metal heat-conducting material.Fin is up-narrow and down-wide to adapt with housing bulb lamp, makes full use of the interior space of housing and dispels the heat.
The radiator of air duct below is extended with the printing opacity cell-shell connecting portion that is used to connect the printing opacity cell-shell; The upper surface of last connecting band is concordant with the fin upper surface; The top of following connecting band embeds in the fin, and the lower surface of following connecting band is concordant with printing opacity cell-shell connecting portion lower surface.
Described printing opacity cell-shell connecting portion is provided with the steam vent of up/down perforation, and the fin of described steam vent and radiator is relative.
Printing opacity cell-shell connecting portion is provided with the cell-shell positioning table terrace that is used for the cell-shell location of ring-type.
The radiator of air duct top is provided with the lamp housing positioning table terrace that is used for the lamp housing location of ring-type.
Be provided with a plurality of profiles with oblique spigot surface that are used for the lamp housing clamping between the adjacent fin, described profile is located at first position of fin.
The described inner top side that goes up connecting band is provided with and is used to the oblique spigot surface that guides the driving power card division to move down, and the madial wall of last connecting band is provided with the limiting section spacing to driving power that be used for of evagination.
Beneficial effect: fin vertically is provided with, and the similar chimney of ventilating duct that adjacent fin forms has swabbing action; Circulation of air is quicker, and cold air is upwards discharged after the annular air channel of bottom gets into vertical ventilating duct, takes away the heat on the fin; Because rapid heat dissipation, therefore available plastics lamp housing replaces the metal shell as thermal component, reduces bulb lamp weight and cost; And avoid the generation of scald accident, and, avoid getting an electric shock because of the lamp housing insulation; The lamp housing appearance design is limited little, can improve the sight of lamp body.Radiator again as the skeleton of light fixture, reduces assembling simultaneously, improves efficiency of assembling, helps reducing the light fixture volume.
