Description

The LED ground light

Technical field

The utility model relates to the LED field, relates in particular to a kind of LED ground light.

Background technology

LED is Light Emitting Diode, the i.e. abbreviation of light emitting diode.LED compares with conventional light source as a kind of emerging light source, possesses following advantage:

Volume is little: the basic structure of LED is that the wafer that volume is very little is encapsulated in the epoxy resin the inside, so overall volume is very little.

Power consumption is low: the LED power consumption is low, and single led power consumption is below 0.05 watt, and the electric light power transfer is high, can reach 30%.Compare energy-conservation reaching more than 50% with conventional light source.

Long service life, firm in structure: LED is the solid cold light source, and by epoxy encapsulation, service life can be big 100,000 hours.Epoxy vertically provides effective protection for inner led chip, and LED does not have loose part, and is not fragile.

Exactly because LED possesses above-mentioned advantage, LED is replacing the main light source that conventional light source becomes commercial and home lighting apace.Various is that the illuminating equipment of basic luminaire continues to bring out with LED.Ground light has in zones such as square, roads widely to be used.Ground etc. are embedded in subsurface, and lamp body structure will bear the weight of pedestrian even vehicle, so the lamp body structure on ground etc. is made into small-sized, firm obturator usually.So, also to have higher requirement for light source wherein, light source must be small-sized, long-life, low heating, stable performance, LED satisfies above-mentioned requirement just.

The utility model content

The utility model is intended to propose a kind of LED ground light.

According to an embodiment of the utility model, this LED ground light comprises metal shell, pedestal, led array plate, reflecting plate, protective stent, high strength glass plate.Metal shell is embedded in underground.Pedestal is fixed on the base plate of metal shell, and pedestal connects external power supply.The led array plate be fixed on the pedestal and with the pedestal electrically conducting, arrange the led light source array on the led array plate.Reflecting plate is arranged on the below of led array plate.Protective stent is fixed on the top of metal shell.The high strength glass plate is fixed on the top of protective stent, and the surface of high strength glass plate is concordant with ground.

In one embodiment, reflecting plate is a speculum.In another embodiment, reflecting plate is an aluminium flake.

In one embodiment, protective stent is latticed.

In one embodiment, the lower surface of high strength glass plate constitutes the concavees lens structure.

The LED ground light compact conformation of the utility model, firm, the led light source volume is little, heating is low, the life-span is long, energy consumption is low, can satisfy the various performance requirements of ground light.

Description of drawings

Fig. 1 has disclosed the cross section structure figure according to the LED ground light of an embodiment of the utility model.

Fig. 2 has disclosed the plane of the protective stent that uses in the LED ground light according to an embodiment of the utility model.

The specific embodiment

Fig. 1 has disclosed the cross section structure figure according to the LED ground light of an embodiment of the utility model.As shown in Figure 1, the utility model proposes a kind of LED ground light, and this LED ground light 100 comprises: metal shell 102, pedestal 104, led array plate 106, reflecting plate 108, protective stent 110, high strength glass plate 112.

Metal shell 102 is embedded in underground, as shown in Figure 1 embodiment, and this metal shell 102 is down trapezoidal shape, and the bottom is less, and the top is bigger.Pedestal 104 is fixed on the base plate of metal shell 102, and pedestal 104 connects external power supply (external power supply does not illustrate) in Fig. 1.Led array plate 106 be fixed on the pedestal 104 and with pedestal 104 electrically conductings.Arrange led light source array 107 on the led array plate 106.Reflecting plate 108 is arranged on the below of led array plate 106.Reflecting plate 108 can be the several piece speculum in one embodiment.In another embodiment, reflecting plate 108 can be an aluminium flake.In the embodiment shown in fig. 1, reflecting plate 108 is several piece speculums, the oblique below that is arranged on led array plate 106, and the effect of reflecting plate 108 is the top open parts that more rays reflexed to metal shell 102, makes that ground light can be brighter.Protective stent 110 is fixed on the top of metal shell 102.Because therefore the weight that the lamp body of ground light will bear pedestrian even vehicle need to use protective stent 110 to increase the bearing capacity of the high strength glass plate 112 on lamp body and surface.In one embodiment, embodiment for example shown in Figure 2, protective stent 118 is latticed, thinks that high strength glass plate 112 provides even and stable support.High strength glass plate 112 is fixed on the top of protective stent 110, and the surface of high strength glass plate 112 is concordant with ground.In the embodiment shown in fig. 1, the lower surface of this high strength glass plate 112 constitutes the concavees lens structure, and the high strength glass plate 112 that is the concavees lens structure can enlarge the range of exposures of ground light, effectively utilizes light more.

The LFD ground light compact conformation of the utility model, firm, LFD light source volume is little, heating is low, the life-span is long, energy consumption is low, can satisfy the various performance requirements of ground light.
