Topic.
Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention for those of ordinary skill in the art without creative efforts, can be with
It obtains other drawings based on these drawings.
Fig. 1 is external plan view of the invention；
Fig. 2 is schematic diagram of internal structure of the invention.
Coding in figure is respectively：1 is heat dissipation metal portion, and 2 be lamp body, and 3 be buried box, and 4 be installation cavity, and 5 be light guide plate,
6 be liquid-collecting box, and 7 be spring, and 8 be coloured cooling fluid, and 9 be inclined surface, and 11 be heat exchanger channels, and 12 be heat-conducting part.
Specific embodiment
As depicted in figs. 1 and 2, this LED underground lamp, including buried box 3, the bottom surface of buried box 3 are provided with an inclined surface
9, the centre of buried box 3 has an installation cavity 4, and 9 side of inclined surface of installation cavity 4 is arranged a heat-conducting part 12, on heat-conducting part 12
End face has a lamp body installation cavity, 2 bottom of lamp body be incorporated in lamp body installation cavity and with 12 thermal contact conductance of heat-conducting part, lamp body 2
Upper end be provided with a heat dissipation metal portion 1, the top dimpling in heat dissipation metal portion 1 can pass through heat dissipation metal in lamp body upper surface
Portion 1 realizes the rapid cooling to entire lamp body, solves the heat dissipation problem of underground lamp, the buried box upper end in face heat dissipation metal portion
Face is provided with a through slot, and the sealing of heat dissipation metal portion buckles into through slot, and heat-conducting part 12 is set to the top one of inclined surface 9
Side；
Buried box 3 runs through far from 2 side of lamp body opens up more than one first slot arranged side by side, each first slot and ground
The installation cavity conducting of box is buried, is inserted into a light guide plate 5 in each first slot, 5 bottom of light guide plate is inserted in installation cavity bottom surface
Liquid-collecting box 6 in, be provided with a liquid collecting cavity in liquid-collecting box 6, the bottom surface of buried box is provided with a heat exchanger channels 11, and heat exchange is logical
Road 11 extends towards 12 one end of heat-conducting part, the coloured cooling fluid 8 of fill part in liquid collecting cavity and heat exchanger channels 11, lamp body 2
Light-emitting surface faces the setting of light guide plate 5.
In the present embodiment, each first slot of 6 upper end face of liquid-collecting box is provided with corresponding second slot, light guide plate bottom
Portion seals and is inserted in the second slot, and a spring 7 is welded and fixed in the bottom surface of the second slot, and 7 top of spring is inserted towards second
Extend in slot, and with 5 lower end face contact of the light guide plate of insertion.Each light guide plate 5 is jacked up upwards and protrudes from buried box 3 by spring 7
Top, therefore when someone tramples, light guide plate is pushed, so that the cooling fluid of bottom extrudes into heat exchanger channels, and most
The heat-conducting part lower end entered eventually, the heat of heat-conducting part is taken away, since entire heat exchanger channels are incline structure, light guide plate
After jacking up under the action of the spring, these cooling fluids can be back to again in the liquid collecting cavity of liquid-collecting box and collect.Due to using guide-lighting
The structure of plate, also there will be no having skidded, solves asking for safety also with regard to none smooth contact surface very well
Topic.
Wherein, coloured cooling fluid 8 is mixed using cooling fluid and colored pigment, and water can be used in cooling fluid.Coloured face
Expect the bottom colors for changing transparent light guide plate, its bottom is enable to change extension when going out light according to coloured cooling fluid, and
And when light guide plate is after pushing, the cooling fluid of congregate can be ejected all, so that the cooling fluid of bottom is pressed into and leads
In the heat exchanger channels of hot portion bottom, at this time since the bottom of light guide plate is without coloured cooling fluid, light guide plate restores its original at this time
The color come after cooling fluid playback, and is restored it and original is had so that light guide plate issues the light of white, and when light guide plate playbacks
Color goes out light.
Buried box 3 is whole to use a metal case, whole opaque, the inside installation cavity wall package setting of buried box
There is one layer of reflective layer.
The beneficial effects of the invention are as follows：One, underground lamp of the invention changes traditional structure being arranged upward, using transverse direction
Guide-lighting mode lights each light guide plate, and the light portion part of underground lamp is exposed in air, can greatly promote lamp body
Heat dissipation performance；
Two, bottom is provided with the type of cooling of override type, and by the way of coloured coolant liquid, it can be realized to lamp body
Change colour and realize the cooling to lamp body bottom simultaneously, increase aesthetics, solve the problems, such as that the rainy day skids, moreover it is possible to solve heat dissipation and ask
Topic.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
The change or replacement expected without creative work, should be covered by the protection scope of the present invention.Therefore, of the invention
Protection scope should be determined by the scope of protection defined in the claims.
