Abstract
The utility model relates to an LED road lamp for easy heat dissipation and dust prevention; a heat-dissipation fin of the existing LED lamp is exposed to air and is easy to catch dust, thereby affecting the service life of the LED; the LED road lamp for easy heat dissipation and dust prevention comprises an LED power supplying circuit and a lamp head, the bottom surface of the lamp head is provided with a plurality of LED lamps, the top surface of the lamp head is provided with a plurality of heat-dissipation fins. The LED road lamp for easy heat dissipation and dust prevention has the advantages of dust prevention, water-proofing, and simple structure and artistic appearance, therefore, the LED road lamp can be widely applied to various municipal luminous environments such as roads and plazas.
Description
Technical field
The utility model relates to a kind of heat radiation, dustproof LED street lamp of being easy to.
Background technology
The LED lighting engineering is flourish, and relevant enterprise is born like the mushrooms after rain.Existing LED light fixture comprises LED power supply circuits and lamp holder, this lamp holder bottom surface is provided with a plurality of LED lamps, the lamp holder end face is provided with a plurality of radiating fins, radiating fin exposes in air, be sticky with dust easily, dust is long-pending more thick more, during work, the LED lamp heats up because of can not in time dispelling the heat, and finally can have a strong impact on the life-span of LED.
The utility model content
The technical problems to be solved in the utility model is the above-mentioned defective that how to overcome prior art, and a kind of heat radiation, dustproof LED street lamp of being easy to is provided.
For solving the problems of the technologies described above, originally be easy to heat radiation, dustproof LED street lamp comprises LED power supply circuits and lamp holder, this lamp holder bottom surface is provided with a plurality of LED lamps, and the lamp holder end face is provided with a plurality of radiating fins.Described radiating fin is vertical, parallel arrangement, and has a plurality of through holes.Radiating fin is vertical, is convenient to wash away dust by rainwater; The radiating fin parallel arrangement is convenient to circulation of air.
After radiating fin was offered through hole, when wind is blown between the radiating fin, the radiating fin two sides can stir dust and produce pressure differential because of the wind speed difference, and it can't be stopped on radiating fin.When wind from just when radiating fin blows, the existence of through hole helps wind by the entire heat dissipation fin, the wind of back row's radiating fin can not occur brushing, the problem that is stopped by front-seat radiating fin.
As optimization, transparent cover plate also is stamped in described lamp holder bottom surface, and described LED lamp just is arranged between lamp holder bottom surface and the transparent cover plate, and transparent cover plate is provided with a plurality of integrally formed lens, and the LED lamp is identical with the lens number, the position correspondence.So design, integrally formed lens are easy for installation, and are aesthetic in appearance.
As optimization, be provided with the waterproof sealing rubber cushion between described lamp holder bottom surface and the transparent cover plate.So design, good water-proof effect.
As optimization, described LED power supply circuits are arranged in the box body at the lamp holder back side, and described LED power supply circuits are arranged in the box body at the lamp holder back side, and box body and radiating fin are together exposed.Heat radiation is convenient in so design.
As optimization, described box body is provided with in the radiating fin clump.So design, compact conformation, box body good heat dissipation effect.
The utility model is easy to dispel the heat, dustproof LED street lamp has dustproof, waterproof, advantage simple in structure, aesthetic in appearance, is widely used in various street illumination environment such as road, square.
Description of drawings
Below in conjunction with accompanying drawing to originally be easy to heat radiation, dustproof LED street lamp is described further:
Fig. 1 be originally be easy to dispel the heat, the structural representation of dustproof LED street lamp embodiment one;
Fig. 2 be originally be easy to dispel the heat, the structural representation of dustproof LED street lamp embodiment two.
Among the figure: 1 is that lamp holder, 2 is that radiating fin, 3 is that through hole, 4 is that transparent cover plate, 5 is that waterproof sealing rubber cushion, 6 is box body.
The specific embodiment
Embodiment one: as shown in Figure 1, originally be easy to heat radiation, dustproof LED street lamp comprises LED power supply circuits and lamp holder 1, the bottom surface of this lamp holder 1 is provided with a plurality of LED lamps, the end face of lamp holder 1 is provided with a plurality of radiating fins 2, it is characterized in that: described radiating fin 2 vertical, parallel arrangements, and having a plurality of through holes 3, shape is square.
Be provided with waterproof sealing rubber cushion 5 between the bottom surface of described lamp holder 1 and the transparent cover plate 4.Described LED power supply circuits are arranged in the box body 6 at the lamp holder back side, and this box body 6 is arranged in 2 clumps of the radiating fins, and together expose in air with radiating fin 2.
Embodiment two: as shown in Figure 2, global shape is spherical in shape, and through hole 3 shapes are rounded, and other structures are shown in enforcement mode one.
Claims (5)
