Description

High-power LED street lamp

Technical field

The present invention relates to lighting field, relate in particular to a kind of high-power LED street lamp of perfect heat-dissipating.

Background technology

The street lamp that uses on the road all is 150W-400W now, and the illumination power source normally consumed power is very big, because general street lamp demand electricity supply is very big, brings very big pressure for the consumption of the energy, and can only under electric power provides sufficient situation, could use normally, simultaneously in actual applications, consider that for economize on electricity the brightness of street lamp need be regulated in different time sections, as the dead of night, street lamp will be transferred secretlyer, with using electricity wisely.And general street lamp adopts common fluorescent lamp or sodium vapor lamp, for brightness is reduced, can only be allowed to condition at the state work down that is lower than rated power, and these lamps very easily damage fluorescent tube being lower than to work under the abnormal operating state of its rated power for a long time, make that the fluorescent tube turnover rate is too high, maintenance cost significantly rises.Street lamp is owing to normally be erected on the electric pole, and bulb service life is short, often need change.Overhaul, safeguard and fix a breakdown and bring inconvenience to circuit pipeline simultaneously.This has not only increased the cost of illuminator, has also increased the consumption of the energy simultaneously.When supply of electric power occurs when in short supply, the illumination of street lamp will be restricted.Be exactly existing LED street lamp in addition, it is very low all to form its work effectiveness by 100 to 300 LED, and low nothing development future is renderd a service in illumination, brightness of illumination must be improved, increasing operating efficiency could use, and now can't satisfy lighting requirement, will be subjected to influence to a certain degree.Provide illumination if adopt some great power LED light emitting diode series connection or parallel connection to be packaged into lighting bulb, the quantity of the great power LED light emitting diode that can enable by controller control (concrete quantity according to required brightness settings, technical) and change lamplight brightness easily by subregion control realization to the LED light emitting diode.Because LED light emitting diode power consumption is little, long service life (life-span is more than 100,000 hours in theory), thereby have great advantage at tool aspect energy-conservation and the cost control.LED white-light illuminating lamp is compared with the fluorescent lamp halogen lamp with conventional incandescent, theoretically, all has absolute predominance at aspects such as power consumption, life-span, environmental protection.The LED bulb power consumption of equal brightness has only 10% of incandescent lamp.Its life-span can reach 100,000 hours, than long 10 times of fluorescent lamp, than long 100 times of incandescent lamp.But existing LED lamp does not adopt perfect heat-dissipating cooling modular construction, and LED lamp power is little still can normally to be used, and when LED lamp power was big, the heat that the LED lamp sends can not well distribute, and causes the damage of LED lamp to be scrapped, and influences people's normal use.

Summary of the invention

Technical problem to be solved by this invention is at above-mentioned deficiency, the high-power LED street lamp of provide a kind of perfect heat-dissipating, reasonable in design, being convenient to install, and it can satisfy the high-power illumination needs of street lamp.Its moulding fineness has energy-conservation, heat radiation and automatic protection functions structure.

The present invention solves the problems of the technologies described above the technical scheme that is adopted: high-power LED street lamp, comprise heat dissipation base, be embedded with at least three LED lamps that are connected in the heat dissipation base concave bottom surface, heat dissipation base recess periphery is fitted with diffuser, the technical measures of taking comprise: have the bar body radiator of ad hoc meter with the corresponding outside of heat dissipation base concave bottom surface, LED lamp lamp sleeve is connected to corresponding lens, clamped the lens securing cover plate between heat dissipation base and the diffuser, this lens securing cover plate is shaped on the lens opening with the corresponding number of LED lamp, and the lens end is through the lens opening build-in of correspondence.

The technical measures of taking also comprise:

For satisfying multiple connecting, being connected to of LED lamp is in series or parallel connection.

More effectively dispel the heat for increasing lamp body component rear end heat conduction efficiency, the bar body radiator of present embodiment is vertical bar shape or ring strip, and profile is plane or ellipsoid.

For being used for changing required illuminating effect, the front end printing opacity screen of diffuser is versicolor glass or plastics.

Be more convenient for accelerating the conduction of heat, be convenient to heat radiation, run through fixing through second securing member between heat dissipation base, lens securing cover plate and the diffuser.

In order to utilize the street lamp shell, the lamp pole dispels the heat in the earth by object and gas, thereby has solved heat dissipation problem; This cooling system is in order to regulate the heat on the internal heat dissipating base.For this reason, be shaped on through hole on heat dissipation base circular pullover, this through hole be penetrated with can be equipped mutually with street lamp post first securing member.For ease of close fit, and should be equipped with the folder mouth by the pullover end shoulder of circle, clamp the lens securing cover plate.

Heat dissipation base and lens securing cover plate are made by the aluminium of perfect heat-dissipating.

The inner chamber that heat dissipation base and lens securing cover plate form is equipped with constant current regulated power supply, and this constant current regulated power supply is electrically connected described LED lamp through lead.

Compared with prior art, what the present invention adopted has the bar body radiator of ad hoc meter with the corresponding outside of heat dissipation base concave bottom surface, LED lamp lamp sleeve is connected to corresponding lens, clamped the lens securing cover plate between heat dissipation base and the diffuser, this lens securing cover plate is shaped on the lens opening with the corresponding number of LED lamp, and the lens end is through the lens opening build-in of correspondence.Its perfect heat-dissipating, reasonable in design, be convenient to install.Have energy-conservation, the moulding fineness, overall shape is with material manufacturings such as high-quality plastics, glass aluminiums; And has automatic protection functions; Characteristics such as applied widely, power savings is remarkable, and price comparison is low.
