Description
Technical field
The utility model patent relates to lighting field, relates in particular to a kind of LED street lamp
Background technology
Characteristics such as the LED lighting tool has that colourity is good, non-maintaining, the life-span is long, in the energy more and more nervous today, the LED street lamp replaces city large electricity consumer's conventional road lamp illumination, is the inexorable trend of future development.But because technical reason, the LED caloric value is big, and heating is having a strong impact on light decay and the life-span of LED, so the applying of LED, heat radiation is the key technology that must resolve, is restricting the development of LED.Existing on the market LED street lamp, is many with lamp housing as the mode of LED radiator, in such light fixture, be separated with aluminium base, heat pipe and aluminium lamp housing between LED and radiating fin, aluminium base particularly, quote in a large number in the LED street lamp, though be coated with heat-conducting silicone grease, the thermal resistance of aluminium base is still influential to the conduction of heat.Present LED street lamp is civil power is supplied to every LED lamp by main line a power supply, and then by power supply civil power is transformed to direct current and is supplied to the LED lamp, this civil power is directly powered given the pattern of dividing lamp, in the street lamp maintenance process and under the situation of electric wire breakage, security incident takes place very easily.
Summary of the invention
Technical problem to be solved in the utility model is exactly at above-mentioned deficiency, and a kind of perfect heat-dissipating be provided, save the energy, safe and reliable a kind of LED road lamp system.
The purpose of this utility model can be achieved through the following technical solutions, and the LED road lamp system comprises a cover light fixture cooling system and a cover electric supply system.
The LED street lamp is characterized in that: LED lamp bottom directly is installed on the cooling system,
The LED street lamp is characterized in that: cooling system is a finned cavity,
The LED street lamp is characterized in that: cooling or heat-conducting liquid are arranged in the finned cavity,
The LED street lamp is characterized in that: the one side of finned cavity has circuit board, and LED lamp pin is welded on the circuit board, and the LED bottom directly links to each other with cavity by heat-conducting silicone grease,
The LED street lamp is characterized in that: the LED light fixture is powered by the film cabinet is unified,
The LED street lamp is characterized in that: the power cabinet power supply is the direct current safe voltage,
Compared with prior art, what the utility model adopted is that LED lamp bottom directly is installed on the design on the band fin cavity, reduced thermal resistance effectively, cooling or heat-conducting liquid are arranged in the cavity, infusion port and exhaust outlet are arranged on the cavity, the effective air in the emptying cavity, liquid can carry out the heat of heat conduction LED lamp fast and distribute by fin, and the conductive performance of LED lamp heat is effectively strengthened.Power supply is unified power cabinet safe voltage power supply, is direct current safe voltage, the phenomenon of effectively having avoided the generation of security incident and steal electricity on public lighting circuit from what power cabinet came out, because be low-voltage power supply, the main line construction cost also reduces greatly, and equipment fault point is few, and is easy to maintenance.

The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing
Typical structure of the present utility model sees that Fig. 1 Fig. 2 is shown in Figure 3, and the light fixture cooling system includes the cavity 7 that liquid 8 is housed, circuit board 9, LED lamp 10.At least one LED lamp 10 is installed on the bottom of cavity 7 after heat-conducting silicone grease 11 is smeared in the bottom, one square circuit board 9 is respectively arranged at pin place, the both sides of LED lamp 10, circuit board 9 is fixed on the bottom of cavity 7, pin is welded on an end of circuit board 9, the other end welds a pin of next LED lamp 10, and remaining LED lamp 10 is installed successively.Cooling or heat-conducting liquid 8 are arranged in the cavity 7, plane one end has two holes on cavity 7, two pipes reach cavity 7 in, form infusion port 4 and exhaust outlet 5, cavity 7 is kept flat, make infusion port 4 and exhaust outlet 5 highly about equally, then liquid 8 is arrived in the cavity 7 by infusion port 4, when exhaust outlet 5 has liquid 8 to flow out, seal exhaust outlet 5 with exhaust outlet capping 13, when infusion port 4 has liquid 8 to flow out, seal infusion port 4 with infusion port capping 12, promptly finish the process of transfusion, if after work after a while, need replenish liquid 8, only need to repeat this process and get final product.The form that this cooling system can be used as light fixture exists, and also can be used as parts in the light fixture.
Typical structure of the present utility model is seen shown in Figure 4, and LED street lamp power supply, road lamp power supply system includes dc source 1, power main 2, power cabinet 3.Power cabinet 3 is input as civil power 380V voltage, is output as the following direct current safe voltage of 36V, by power main 2 voltage is transported to some LED street lamps.
Though the utility model only illustrates and describes by embodiment; but those skilled in the art should understand, in the scope of claims, to the varying number and the shape of cavity 7; the varying number of LED lamp all belongs to protection domain of the present utility model.
