2, by each heat-delivery surface of LED lamp in the link of function of environment heat emission, its convection type carries out affecting junction temperature in heat transfer and rises three factors such as the temperature difference because have the coefficient of heat transfer, effective heat exchange area, heat exchange surface and fluid of Δ t.Specifically can be as follows with following equation expression:
Δt2＝Q2/hc·A；
Wherein, Q2 represents heat loss through convection amount, and unit is W; Hc represents the coefficient of heat transfer, and unit is W/m
2a; A represents effective heat exchange area, and unit is m
2; Δ t2 represents heat exchange surface and fluid temperature difference, and unit is DEG C.
The present embodiment devises the heat radiation inner casing 40 upwards extended in connecting plate 30 centre, the stack effect formed thus can improve the coefficient of heat transfer on this surface significantly, simultaneously because this enforcement is using the surfaces externally and internally of whole LED lamp as effective heat exchange area, its area has been greater than traditional fin radiating structure, and therefore this structure has good heat loss through convection effect.The very effect considering heat loss through radiation of simultaneously traditional fin radiating structure not more, in fact, not far owing to being separated by between fin, the effect of heat loss through radiation is almost offset completely by the absorption of adjacent fin and inoperative, but in the LED lamp 100 of the present embodiment, the surfaces externally and internally due to whole LED lamp is smooth structure, therefore, heat loss through radiation also plays a significant role, and This further reduces junction temperature and rises Δ t.
