2; Δ t1 represents this section of heat-transfer path two ends temperature difference, and unit is DEG C; L represents heat-transfer path length, and unit is m.
The present embodiment have employed the placement scheme of dispersed placement of being tried one's best by light-emitting component 20, equivalence on the unit heat sink material wasted work rate Q1 that falls apart significantly is reduced, add the heat carrier sectional area of equivalence simultaneously, also making full use of structural design in addition makes the loose heat consumption of LED conduct heat, to reach better radiating effect to connecting plate 30 center and outer cover 10 with as far as possible equal distance.
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.
This enforcement is using the surfaces externally and internally of whole LED lamp as effective heat exchange area, and 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.
