Among the utility model embodiment, the LED substrate 21 of described ball bubble shape LED light fixture is sealed in first sealed cavity 201 of described inner seal cover 24 inner surfaces and substrate holder 22 tops formation, and described cooling fluid is filled in the inner surface by outer light distributing cap 23, the outer surface of the outer surface of substrate holder 22 and inner seal cover 24 forms in second sealed cavity 202, LED substrate 21 is with in described cooling fluid is located in different sealed cavities like this, reach the effect of isolation, make LED substrate 21 no longer be immersed in the described cooling fluid, prevented the corrosion of cooling fluid thus, prevented that simultaneously cooling fluid from penetrating in the chip on the LED substrate 21 LED substrate 21.
Among the utility model embodiment,, therefore when cooling fluid is selected, needn't consider again that cooling fluid can constitute the problem of corrosion to LED substrate 21 because described LED substrate 21 no longer is immersed in the described cooling fluid.At this moment, the liquid that only needs to select good heat dispersion performance need not be considered corrosive height of this liquid again as cooling fluid, and thus, the selectance of described cooling fluid is higher.For example, the water that can select perfect heat-dissipating and less expensive not only is easy to realization but also can well realizes radiating effect as cooling fluid.
Among the utility model embodiment, substrate holder 22 has good thermal conductivity.When the led light source on the LED substrate 21 20 carries out luminous generation heat, because LED substrate 21 is close to substrate holder 22, substrate holder 22 directly contacts with described cooling fluid, substrate holder 22 can reach described cooling fluid rapidly with the heat that led light source 20 produces, convection current by described cooling fluid again, heat is reached outer light distributing cap 23, reach radiating effect.
Among the utility model embodiment, described LED substrate 21 is close to substrate holder 22 tops, specifically can adopt riveted joint, welding, bonding method.

Among the utility model embodiment, the LED substrate 61 of described bar-shaped LED light fixture is sealed in described first sealed cavity 601, described cooling fluid is filled in described second sealed cavity 602, LED substrate 61 and described cooling fluid reach the effect of isolation like this, make LED substrate 61 no longer be immersed in the described cooling fluid, prevented the corrosion of cooling fluid thus, prevented that simultaneously cooling fluid from penetrating in the chip on the LED substrate 61 LED substrate 61.
Among the utility model embodiment, because described LED substrate 61 no longer is immersed in the described cooling fluid, therefore when cooling fluid is selected, only need to select the liquid of good heat dispersion performance as cooling fluid, need not consider corrosive height of this liquid again, thus, the selectance of described cooling fluid is higher.
Among the utility model embodiment, substrate holder 62 has good thermal conductivity.The heat of led light source 60 luminous generations can reach in the described cooling fluid rapidly by the conduction of substrate holder 62, and then heat can be reached outside the outer light distributing cap rapidly, reaches radiating effect.
Among the utility model embodiment, described LED substrate 61 is close to substrate holder 62 tops, specifically can adopt riveted joint, welding, bonding method.
Preferably, can add heat-conducting medium between LED substrate 61 and the substrate holder 62, strengthen the heat conduction between LED substrate 61 and the substrate holder 62.Concrete, heat-conducting medium can be heat-conducting plate or heat conducting coating.
Among the utility model embodiment, described inner seal cover 64 adopts with substrate holder 62 and is threaded.Preferably, described inner seal cover 64 adopts fluid sealant to seal with the junction of substrate holder 62.
Among the utility model embodiment, inner seal cover 64 is a transparent body.Light enters cooling fluid after seeing through the described transparent body, and described cooling fluid can carry out luminous intensity distribution to light, makes that the light that passes outer light distributing cap 63 is even.
Preferably, described inner seal cover 64 can adopt with LED substrate 61 optics on the light-distribution lens that matches, described light-distribution lens can carry out luminous intensity distribution to light.Pass behind the outer light distributing cap 63 more even through the light behind twice luminous intensity distribution.
In order to prevent that described cooling fluid expanded by heating from causing outer light distributing cap to break, in second sealed cavity 602 of the described bar-shaped LED light fixture of the utility model embodiment, also can keep a certain size bubble.But the not limited timing in position when described bubble may produce hot spot in range of exposures.The utility model embodiment four has effectively solved this problem.
With reference to Fig. 7, be the bar-shaped LED light fixture cross sectional view of the utility model embodiment four.
Among Fig. 7, in described second sealed cavity 602, below described substrate holder 62 and described inner seal cover 64 junctions, increase baffle plate 67, with the fixed-site of bubble 66 bottom at second sealed cavity 602.Because described substrate holder 62 is not the light out part of LED light fixture with the below of described inner seal cover 64 junctions, does not have light to send from this, makes the existence of described bubble 66 can not produce hot spot.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined herein General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
