The LED lamp 100 also includes hook 40 so that the LED lamp 100 is using, can be easily by hook 40
The LED lamp 100 is hung up, for irradiating in the occasion corresponding to its perisporium 11 of outer cover 10.It is it is appreciated that described
Hook 40 is on the roof 13 of the outer cover 10.
It is appreciated that when in use, its outer cover 10 is to be used to enter the light-emitting component 20 to LED lamp 100 in the present embodiment
The heat abstractor of row radiating.Because light-emitting component 20 is to be located at by connecting plate 30 on perisporium 11, therefore perisporium 11 is to luminous member
The position that the radiating of part 20 can be arranged on perisporium 11 according to connecting plate 30 is specifically divided into two heat dissipation paths.Specifically,
It is the first heat dissipation path to define arc length of the perisporium 11 between the connecting plate 30 and the light out part 12, the week
Arc length of the wall 11 between the connecting plate 30 and the opening portion 13 is the second heat dissipation path, first heat dissipation path
Ratio with second heat dissipation path is 1: 100 to 10: 1.When in the present embodiment LED lamp 100 light operation when, it is luminous
Heat is dispersed by the both ends of connecting plate 30 towards perisporium 11 caused by element 20.From the foregoing, it will be observed that in order that obtaining the outer cover 10 has
Balanced heat-sinking capability, and then improve the overall radiating efficiency of LED lamp 100.Preferably, first heat dissipation path and institute
The ratio for stating the second heat dissipation path is 1: 1.
At work, caused heat is by hot interface to LED lamp 100 when its light-emitting component 20 works in the present embodiment
Material is conducted to connecting plate 30, is conducted via the connecting plate 30 to outer cover 10 and is diffused, radiates on whole outer cover 10.
Outwardly radiated by radiation mode and convection type simultaneously on the surface of the connecting plate 30 and outer cover 10.Wherein determine this
Entire thermal resistance existing for the heat dissipation path of the radiating efficiency of LED lamp 100 is equal to it of heat dissipation path links thermal resistance in embodiment
With.After LED lamp energization work enough time, under certain environment temperature and air velocities, LED lamp can integrally reach
To the knot of a thermal balance, the now LED lamp of the temperature difference Δ t meanings between the temperature of the light-emitting component 20 of LED lamp and air
Temperature rise, wherein LED lamp junction temperature liter are more low, mean that LED life expectancy is longer.
The factor that LED lamp junction temperature rises just is influenceed below does following analysis：
More than analysis to heat dissipation path understand the light-emitting component 20 of LED lamp to heat-delivery surface be to being that conduction is scattered
Heat, by each heat-delivery surface of LED lamp, to there is radiation external environment, both modes radiate with convection current, due to different radiatings
Mode is related to different influence factor and computational methods, is discussed respectively below：
1st, during light-emitting component 20 to each heat-delivery surface of the LED lamp is heat loss through conduction extremely, influence junction temperature and rise Δ t
Factor have LED dissipated power, the thermal conductivity factor of various heat sink materials, the sectional area of heat carrier, heat transfer circuit in heat dissipation path
Length in footpath etc. four.So the temperature difference of this section of heat-transfer path can be expressed with below equation：
Δ t1=LQ1/KA；
Wherein, Q1 represents the dissipated power of LED lamp, unit W；K represents thermal conductivity factor, and unit is W/m DEG C；A tables
Show the sectional area of heat carrier, unit m2；Δ t1 represents this section of heat-transfer path both ends temperature difference, and unit is DEG C；L represents heat-transfer path
Length, unit m.
The present embodiment employs the placement scheme for dispersed placement that light-emitting component 20 is tried one's best so that on unit heat sink material
Equivalent scattered wasted work rate Q1 significantly reduces, while adds equivalent heat carrier sectional area, also makes full use of structure design in addition
So that LED scattered heat consumption is conducted heat to the Fixed Division 31 of connecting plate 30 and outer cover 10 with the distance for trying one's best equal, to reach more preferable
Radiating effect.
2nd, from each heat-delivery surface of LED lamp into the link of function of environment heat emission, its convection type influenceed in heat transfer
The factor that junction temperature rises Δ t has three factors such as temperature difference of the coefficient of heat transfer, effective heat exchange area, heat exchange surface and fluid.Specifically may be used
To be expressed as follows with below equation：
Δ t2=Q2/hcA；
Wherein, Q2 represents heat loss through convection amount, unit W；Hc represents the coefficient of heat transfer, unit W/m2·A；A represents effective
Heat exchange area, unit m2；Δ t2 represents heat exchange surface and fluid temperature difference, and unit is DEG C.
Using the surfaces externally and internally of whole LED lamp as effective heat exchange area, its area dissipates more than traditional fin for this implementation
Heat structure, therefore this structure has good heat loss through convection effect.Simultaneously traditional fin radiating structure not too much more considers spoke
The effect of radiating is penetrated, in fact, not far due to being separated by between fin, the effect of heat loss through radiation is several by the absorption of adjacent fin
It is completely counterbalanced by and does not work, but in the LED lamp 100 of the present embodiment, because the surfaces externally and internally of whole LED lamp is
Smooth structure, therefore, heat loss through radiation also play very big effect, and This further reduces junction temperature to rise Δ t.
In summary, LED lamp 100 takes full advantage of radiating principle and reasonable Arrangement LED layout in the present embodiment
And efficient radiator structure is devised using the component of the intrinsic LED lamp such as outer cover, effectively reducing the same of LED junction temperature rise Δ t
When also reduce light fixture cost, simplify assembly technology, maintain the LED lamp 100 there is overall aesthetic property.
