Abstract
The utility model relates to a landscape lighting lamp, in particular to an LED landscape lighting lamp with a metal heat-conduction bar. The LED landscape lighting lamp comprises a bracket, wherein a lamp outer cover is arranged on the bracket; and a lamp shade is fixed on the lamp outer cover. The LED landscape lighting lamp is characterized in that a heat dissipation mechanism is arranged in the lamp outer cover and comprises a heat-conduction bar shell; a cavity is arranged in the heat-conduction bar shell; the metal heat-conduction bar is arranged in the cavity; an LED light source is arranged at the outer side wall of the heat-conduction bar shell; a power supply is arranged at the lower part of the heat-conduction bar shell; and the power supply is connected with the bracket by a transmission line in a penetrating way; therefore, the LED landscape lighting lamp has good heat dissipation effect, the service life is prolonged, and the production cost is controlled.
Description
Technical field
The utility model is a kind of landscape lighting luminaire, particularly a kind of LED landscape lighting luminaire that has the metal heat-conducting rod.
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.
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 metal heat-conducting rod 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 that has the metal heat-conducting rod, comprise support, support is provided with the light fixture outer cover, be fixed with lampshade on the light fixture outer cover, it is characterized in that: be provided with cooling mechanism in the described light fixture outer cover, described cooling mechanism comprises the heat conductive rod housing, is provided with cavity in the heat conductive rod housing, is provided with the metal heat-conducting rod in the cavity; Heat conductive rod hull outside wall is provided with led light source, and 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.The radiator that is installed in the led light source in the enclosed environment is coupled together the radiator structure of light source and extraneous air by the metal heat-conducting rod, 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, described metal heat-conducting rod is " T " shape, and the tip and the lampshade of metal heat-conducting rod are fixedly connected, and two the heat conduction ends and the heat conductive rod housing of metal heat-conducting rod fix.
As preferably, two lateral walls of described heat conductive rod housing are respectively equipped with led light source.
Therefore, the utility model provides a kind of LED landscape lighting luminaire that has the metal heat-conducting rod, and excellent in heat dissipation effect increases the service life, and controls production cost simultaneously.
