Description
Technical field
The utility model relates to a kind of underground lamps, belong to headlamp technical field.
Background technique
Underground lamp is mounted in the lamps and lanterns on the ground such as lawn, square for illumination, but existing underground lamp is often deposited
In the defect that infiltration and heat can not dissipate, the illumination efficiency of underground lamp and the service life of lamps and lanterns are seriously affected, though have to this numerous
Innovative solutions, but effect is not satisfactory.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of underground lamps, it has, and sealing is excellent, heat dissipation is good
Well, the characteristics of overcoming the sealing of the prior art insufficient and heat dissipation undesirable defect.
Technical problem to be solved in the utility model takes following technical scheme to realize:
A kind of underground lamp, including top cover, lamp body and glass cover are provided with pcb board, LED light and thoroughly in the lamp body
Mirror, power supply, the upper surface of lamp body are equipped with flange face, set heavy hole on flange face, sink hole bottom surface equipped with interior seal groove, external seal
It is furnished with sealing ring in slot, interior seal groove and external seal slot, the depth of the external seal slot is greater than the depth of interior seal groove, described
Sealing ring section be "" type or "" type；There is a between outer land terrace in the upper end of glass cover, and the lower end surface of top cover has
One interior step surface for matching between outer land terrace and mutually pressing, the lower end of glass cover is pressed in heavy hole, and squeezes sealing
Circle is so that glass surface covers the centre of end face and top cover upper surface maintains an equal level；It is additionally provided with radiator in the lamp body, radiates
One end of device is connected by connecting column with lamp body bottom end, and the other end is fixed on the lower end surface of pcb board.
The power supply is mounted in the gap between radiator and lamp body bottom end.
The lamp body bottom end is equipped with waterproof screw.
The depth of interior seal groove certain value smaller than the distance of sealing ring upper surface to shorter enclosure bottom end, the depth of external seal slot
Certain value smaller than the distance of sealing ring upper surface to longer enclosure bottom end is spent, the definite value is equal to the optimal compression amount of sealing ring.
The beneficial effects of the utility model are: the centre of glass cover is thicker, can maintain an equal level with the upper surface of top cover, and
And it can increase the intensity at glass cover center；Since the depth of inside and outside seal groove is fixed, it is ensured that in top cover or glass
When cover is trampled repeatedly by pedestrian and vehicle rolls sealing ring not will receive it is related roll, to avoid sealing ring due to repeatedly
The initial failure by additional alternate stress effect, the depth of interior seal groove is greater than using two seals and the depth of external seal slot
Degree can make Leakage probability reduce multiple orders of magnitude；Setting radiator accelerates the intracorporal heat of lamp outward to increase heat dissipation area
Conduction is dissipated.
Detailed description of the invention
Fig. 1 is a kind of example structure schematic diagram of the utility model.
In figure: top cover 1；Lamp body 2；Flange face 21；External seal slot 22；Interior seal groove 2；Glass cover 3；Between outer land terrace 31；
