The specific embodiment
Understand for technical characterictic of the present utility model, purpose and effect being had more clearly, now contrast the description of drawings specific embodiment of the present utility model.
The following description will cooperate diagram to do explanation, and wherein, according to an embodiment of the present utility model, the led circuit plate 80 in the diagram only is an example, is not in order to limit claim of the present utility model.For example the arrangement mode of the led chip in the led circuit plate 80 is not limited to illustrated a kind ofly, and it can be single many or arrange many more, even can the framework lens on the led chip, and all be that skilled person can change.In a preferred embodiment, then be single, or double, so, can be so that the every LEDs chip of every row all obtains immediate radiating condition in the lamp bar.
Above-mentioned another advantage perpendicular to the axial radiating fin 40 of fluorescent tube provides rainwater and the shortest discharge path of dust.Compared to known fluorescent tube radiating fin be parallel to more major axis to so that when raining, water can be residual.In addition, sand and dust easily are piled up between the groove of radiating fin.Sand and dust are except the influence heat radiation, and another shortcoming is the sand and dust shielded area and shielded area potential difference not can produce current potential corrosion problem.The utility model fluorescent tube radiating fin 40 arranged verticals can be improved aforesaid problem.
The concave surface platform 18 of fluorescent tube inside then is provided with an inclined-plane 38 (slope groove surface) near adjusting axle 25 places, with the power line 31 of ccontaining led circuit plate 80.Platform 18, inclined-plane 38 and radiating fin 40 are formed in one.After Fig. 1 C shows that the led circuit plate 80 with Figure 1A is locked in platform 18, the stereogram after lampshade 19 covers in addition.
Radiating fin 40 is at identical volume perpendicular to another benefit that the axial E-W of fluorescent tube distributes, same radiating fin 40 height are with following at interval, radiating fin 40 gross areas that the utility model distributed are apparently higher than the person of paralleling to the axis (be the long limit of fluorescent tube when being East and West direction, radiating fin also is an East and West direction).Bigger area of dissipation mean no matter be the thermal source of LED lamp 17 with heat exchange pattern or thermal convection current mode, bigger area of dissipation can be brought into play better radiating effect.
With an embodiment, the thickness of radiating fin 40 is 0.2mm, wide 50mm, be spaced apart 2.8mm, be erected on the semicolumn surface of the light tube of long 300mm, but than the long-pending thickness 0.2mm that is being arranged in parallel of identical semi-cylinder surface, the radiating fin of long 300mm is all the radiating efficiency of the big dozens of percentage of 2.8mm person at interval.
According to newton's thermal convection current law of cooling
Q=hA (T
s-T
f), wherein h is the coefficient of heat convection, the coefficient of heat convection is not to be the physical property of fluid, but can be subjected to geometry, the fluid flow phenomena of contact surface, the isoparametric influence of physical property of fluid.That is h and fluid are to present relevantly with laminar flow, transition flow or eddy-currents, and at this, fluid is meant air.Wherein, the heat conduction that eddy-currents heat can provide is best, and transition flow is taken second place.As previously mentioned, the utility model radiating fin is arranged in the vertically and horizontally arranged method of semi-cylinder surface, than any ranking method of plane formula and be all and be formed at the semicylinder surface, but elongated ranking method, in the street lamp environment for the open air use, the cold air at night can provide the street lamp heat radiation required better thermal convection current.Therefore, the importance of thermal convection current more is far more than heat conduction, that is how to make that the air-flow by fluorescent tube can be fully and radiating fin backflow carrying out thermal convection current.The ranking method of above-mentioned radiating fin 40 of the present utility model (comprising large and small radiating fin), though, little heat radiating fin sector-meeting reduces area of dissipation, but can make easier large and small radiating fin 40A, the 40B that enters fluorescent tube housing 10 of ambient windstream, and makes that the h value is even better.In addition, radiating fin 40 is the class bat and launches the double-vane shape, and preferable thermal convection current environment further is provided.Particularly, shown in Fig. 1 D, radiating fin 40 center lines 41 (body between double-vane) are lower, therefore, fluorescent tube top ambient windstream are dispersed among each radiating fin 40 and the effect of performance thermal convection current.
According to experimental result, fluorescent tube of the present utility model can make effectively that the led chip temperature declines to a great extent, and particularly under the environment of zephyr, the led chip temperature is effectively reduced, and please refer to the experimental data of table one.
