Description
Technical field
The utility model is a kind of landscape lighting luminaire, particularly a kind of LED landscape lighting luminaire that has the liquid level cooling mechanism.
Background technology
Because the special applications character of landscape lighting luminaire is the function based on view, take into account the function of illumination, this point is different with the application function of road illuminating lamp, therefore, their application mode be with space illumination towards periphery or upward irradiation be majority, Zhao She light fixture is less downwards, this light projector mode self just is unfavorable for the heat dissipation design and the heat conduction of light source, the light source of present various LED landscape lighting luminaire and radiator great majority are to be enclosed in the ornamental lampshade, the radiator structure of light source can not directly carry out heat loss through convection with extraneous air, so the radiating condition of light source and heat dissipation environment are extremely disadvantageous.Compare with the traditional lighting light fixture, their light source is the hot operation light source, needs to carry out heat dissipation design hardly, and design for aesthetic becomes traditional landscape lighting luminaire main design contents.The LED lighting is then different, it is a kind of low-temperature working light source, must guarantee that light source works is a relatively low temperature range, to guarantee that light source can not produce quick light decay, therefore, its heat dissipation design will be far above design for aesthetic, if continue to use the mentality of designing of traditional landscape lighting luminaire, light source can be in high-temperature work environment, and light source can produce quick light decay, and this is the main cause of more present LED landscape lighting luminaire " life-span is short ".
Chinese patent CN101539285 discloses a kind of LED radiating loop structure, comprises heat sink, and described heat sink is a hollow sheeting, is filled with thermal liquid in the described heat sink, links to each other with aluminium base below the described heat sink.Described heat sink comprises hot plate, hollow pipe and following hot plate, and the described hot plate of going up connects hot plate down by hollow pipe, and described hot plate down links to each other with aluminium base, and described aluminium base links to each other with the device of sealed lamps.Described hollow pipe is arranged on the two ends of hot plate.Described hollow pipe is 4, and a described end of going up hot plate is provided with two hollow pipes.Described surface of going up hot plate, hollow pipe and following hot plate all scribbles far ultrared paint.The disclosed heat-radiation loop of this patent of invention mechanism, radiating effect is not good, and the structure relative complex, and liquid under the environment that colds and heat succeed each other, destroys heat sink easily in the heat sink, causes the product reduction in service life.
Summary of the invention
The utility model mainly is to solve the deficiencies in the prior art, and a kind of LED landscape lighting luminaire that has the liquid level cooling mechanism is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of LED landscape lighting luminaire, comprise support, support is provided with the light fixture outer cover, be fixed with lampshade on the light fixture outer cover, be provided with the liquid level cooling mechanism in the described light fixture outer cover, described liquid level cooling mechanism comprises the heat conductive rod housing, is provided with cavity in the heat conductive rod housing, be provided with liquid in the cavity, be provided with liquid level in the cavity and regulate balloon; Regulate the corresponding heat conductive rod hull outside of balloon wall with liquid level and be provided with led light source, the heat conductive rod lower part of frame is provided with power supply, and power supply is crossed in the support by the power transmission line cross-under.When led light source is started working, produce thermal source, fluid temperature rises, because of being filled with air in the liquid level adjusting balloon, cause liquid level to regulate the increase of balloon volume, the heat that LED produces is transported in heat-conducting metal rod or the metal shade, and the liquid in the heat conductive rod housing has antifreeze ability, the balloon position line is used for locating liquid level and regulates balloon, prevents that balloon from having gone to the top of liquid; Liquid in the cavity is discontented with, so just prevented to destroy cavity when colding and heat succeed each other when the liquid process, prolong the life-span of using: the radiator that will be installed in the led light source in the enclosed environment couples together the radiator structure of light source and extraneous air by the liquid convection heat conductive bar, the heat delivery that led light source produces is to the metal shade on view light fixture lamp body top, being beneficial to the bigger metal shade of area dispels the heat, thereby the heat that led light source produces is transported to the outside in sealed light chamber fast, guarantees that light source can not produce quick light decay.
As preferably, the top of described heat conductive rod housing is provided with the heat-conducting metal rod, and heat-conducting metal rod and the liquid in the cavity contact; The lower end that liquid level is regulated balloon is provided with the balloon position line, and balloon position line and heat conductive rod housing are fixedly connected.
As preferably, two lateral walls of described heat conductive rod housing are respectively equipped with led light source.
As preferably, described lampshade is taper, and the length of the lamp wing on lampshade both sides is greater than the lateral wall of light fixture outer cover.
Therefore, the utility model provides a kind of LED landscape lighting luminaire, and excellent in heat dissipation effect increases the service life, and controls production cost simultaneously.
