The specific embodiment

With reference to Fig. 2, Fig. 3, a kind of integral compact LED lamp, comprise lamp body 1, radiator 2 and light source pcb board 3, this radiator mainly is made of radiating fin 10, radiating fin 10 is tabular, described lamp body 1 and radiator 2 adopt extrusion process integrated die-casting moulding or adopt the PM technique integrated injection molding, radiator 2 is positioned at lamp body 1 inboard, material selection aluminium alloy (ADC12), be provided with through wires hole 5 on the lamp body 1, the connection wire of light source pcb board 3 spreads out of from through wires hole, connects outside power supply.

With reference to Fig. 1, the first of described radiator 2 is implemented structure: form the equal piecemeal 4 of a thermal-arrest at the inside of radiator 2 integrated die-casting, the equal piecemeal of thermal-arrest 4 fronts are the plane, the back side is arc-shaped recess, heat energy is under the shape of similar arc-shaped recess, can conduct the most fast and effectively, play simultaneously the cross-ventilation effect of similar stack effect.Described light source pcb board 3 is fitted in the front of the equal piecemeal 4 of described thermal-arrest, in order to strengthen the effect of heat radiation, is provided with heat conduction copper sheet 6 between the equal piecemeal 4 of described light source pcb board 3 and described thermal-arrest.

The heat energy that light source pcb board 3 produces fast by heat conduction copper sheet 6 with heat to around scatter, and then be transmitted to uniformly backward on the equal piecemeal 4 of thermal-arrest, the equal piecemeal 4 of thermal-arrest distributes to radiating fin 10 again, and heat penetration is crossed fin derive, it is even that this is conducive to the radiating subassembly variations in temperature, is convenient to heat and distributes rapidly.

One end of radiating fin 10 is connected with the equal piecemeal of thermal-arrest, the connecting portion of radiating fin and the equal piecemeal of thermal-arrest adopts the circular arc chamfering structure, the connecting portion of radiating fin and lamp body also adopts the circular arc chamfering structure, common R＞=the 3mm of the radius size of circular arc chamfering can satisfy the needs of heat radiation, usually R＞=5mm radiating effect can be better, the structure of this circular arc chamfering is extremely important, the heat of being led fin just begins to the air transmitted heat in the process of conduction, remaining heat is transmitted to lamp body again, same fin is connected the circular arc chamfering that connects with lamp body extremely important equally, and these circular arc chamferings are conducive to the transport efficiency of heat.

With reference to Fig. 2, Fig. 4, the center of described radiator 2 is provided with a cavity 8, and a heat conduction copper sheathing 7 is installed in the described cavity 8, and described light source pcb board 3 is fitted on the end face of described heat conduction copper sheathing 7.
