This LED lamp 100 also comprises hook 40, making this LED lamp 100 in use, can easily this LED lamp 100 being hung up, for irradiating in the occasion corresponding to its outer cover 10 perisporium 11 by linking up with 40.Be appreciated that described hook 40 is located on the roof 13 of described outer cover 10.
Be appreciated that in the present embodiment, LED lamp 100 in use, its outer cover 10 is the heat abstractors for dispelling the heat to this light-emitting component 20.Because light-emitting component 20 is located on perisporium 11 by connecting plate 30, the position that therefore heat radiation of perisporium 11 pairs of light-emitting components 20 can be arranged on perisporium 11 according to connecting plate 30 is specifically divided into two heat dissipation path.Particularly, defining the arc length of described perisporium 11 between described connecting plate 30 and described light out part 12 is the first heat dissipation path, the arc length of described perisporium 11 between described connecting plate 30 and described opening portion 13 is the second heat dissipation path, and the ratio of described first heat dissipation path and described second heat dissipation path is 1:100 to 10:1.When in the present embodiment during LED lamp 100 luminous operation, the heat that its light-emitting component 20 produces is left by the two ends of connecting plate 30 towards perisporium 11.As from the foregoing, in order to make this outer cover 10 have balanced heat-sinking capability, and then improve the radiating efficiency of LED lamp 100 entirety.Preferably, the ratio of described first heat dissipation path and described second heat dissipation path is 1:1.
In the present embodiment, LED lamp 100 operationally, and the heat produced when its light-emitting component 20 works conducts to connecting plate 30 by thermal interfacial material, conducts to outer cover 10 and carry out spreading, dispelling the heat on whole outer cover 10 via described connecting plate 30.Outwardly dispelled the heat by radiation mode and convection type in the surface of described connecting plate 30 and outer cover 10 simultaneously.Wherein determine that the entire thermal resistance of the heat dissipation path existence of LED lamp 100 radiating efficiency in the present embodiment equals the sum of heat dissipation path links thermal resistance.After LED lamp energising work enough time, under certain environment temperature and air velocities, LED lamp entirety can reach a thermal balance, the junction temperature liter of the LED lamp of the temperature difference Δ t meaning now between the temperature of the light-emitting component 20 of LED lamp and air, wherein LED lamp junction temperature rises lower, means that the life expectancy of LED is longer.
The factor risen with regard to affecting LED lamp junction temperature below does following analysis:
By the light-emitting component 20 of the known LED lamp of the above analysis to heat dissipation path to heat-delivery surface for being heat loss through conduction, dispel the heat by having radiation and these two kinds of modes of convection current LED lamp each heat-delivery surface to external environment, because different radiating modes relates to different influence factors and computational methods, discuss respectively below:
1, light-emitting component 20 to each heat-delivery surface of this LED lamp be to heat loss through conduction process in, affect the thermal conductivity factor, the sectional area of heat carrier, the length of heat-transfer path etc. four because have various heat sink material in the dissipated power of LED, heat dissipation path that junction temperature rises Δ t.So the temperature difference of this section of heat-transfer path can use following equation expression:
Δt1＝L·Q1/K·A；
Wherein, Q1 represents the dissipated power of LED lamp, and unit is W; K represents thermal conductivity factor, and unit is W/m DEG C; A represents the sectional area of heat carrier, and unit is m
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 Fixed Division 31 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.
In sum, in the present embodiment, LED lamp 100 takes full advantage of radiating principle and the layout of reasonable Arrangement LED and utilize the efficient radiator structure of member designs of the intrinsic LED lamp such as outer cover, also reduces light fixture cost, simplifies assembly technology, maintains the aesthetic property that this LED lamp 100 has entirety effectively reducing while LED junction temperature rises Δ t.
