As preferably, described heat dissipation metal substrate consists of the metal fin of a plurality of circumferential array of metallic plate and top of bottom, between arbitrary neighborhood metal fin, leaves gap; The metal fin inner side on heat dissipation metal substrate top surrounds a center cavity for fan wind-guiding, and described center cavity surrounding is communicated with respectively the gap between adjacent metal fin; Gap between adjacent described metal fin is communicated with the air outlet in metal lower shell.
Further, also comprise lampshade, described lampshade is arranged on metal lower shell below; Described air outlet position is in the metal lower shell sidepiece in lampshade outside, and air outlet is opening down.
As preferably, described metal lower shell is aluminum hull, and described heat dissipation metal substrate is aluminum base plate, and described metal lower shell inner side and heat dissipation metal substrate are connected as a single entity.
Adopted the LED bulkhead lamp capable of technique scheme, this LED bulkhead lamp capable has adopted the metal of good heat dissipation effect as lower casing, the heat dissipation metal substrate conducting heat for LED luminescence component is installed in lower casing again, in addition, fan for active heat removal is also installed above heat dissipation metal substrate, fan self mechanical energy conversion ratio is very high, generates heat little, but can increase well the Air Flow in lamp housing.Coordinate adding of this fan, in the lamp design of this LED bulkhead lamp capable, also designed the air inlet flowing into for air, and the air outlet flowing out for air, heat dissipation metal substrate position is between fan and air outlet.The LED bulkhead lamp capable of design, has had active heat removal ability like this, when turning on light, just can by air, be passed in and out and flow through in lamp housing fast well, quick heat radiating.This radiating mode does not only improve too many cost, and is better than any passive heat radiation, and radiating effect is very good, causes LED bulkhead lamp capable long service life of the present utility model.
