Abstract
The utility model discloses an LED (Light Emitting Diode) street lamp which comprises a base, heat radiation bodies and an LED luminophor arranged at the upper part of the base, wherein the heat radiation bodies are strip-shaped heat radiation fins and are arranged at the bottom of the base at intervals. The base of the LED street lamp is provided with the heat radiation fins, so that heat generated by the lighting of the LED luminophor is emitted out through the heat radiation fins to ensure that the service life of the LED street lamp is prolonged and the using cost is reduced.
Description
Technical field
The utility model relates to a kind of light fixture that is used for road lighting, and particularly a kind of illuminance is strong, LED streetlamp with favorable radiating effect.
Background technology
General street lamp adopts mercury vapor lamp, neon light, metal halide lamp etc. as light source more; The LED lamp is new in recent years a kind of technology of rising as road-light light-source; Have efficient, safety, energy-saving and environmental protection, distinct advantages such as the life-span is long, response speed is fast, colour rendering index height; Just progressively replace conventional road lamp, be widely used in city illumination.But all requirements to some extent of illumination brightness of LED street lamp and illumination zone; So the LED that adopts generally is a high-power LED; The heat that produces when high-power LED lamp is luminous is quite big; And the LED lamp to the heat radiation requirement than higher, therefore, how designing the LED street lamp that a brightness of illumination is strong, illumination zone is big, radiating effect is good is the technical problem that needs to be resolved hurrily in the industry.
Summary of the invention
The main purpose of the utility model provides a kind of LED street lamp, is intended to accelerate the radiating rate of LED, prolongs the service life of LED street lamp.
The utility model proposes a kind of LED street lamp, and the LED illuminator that comprises base, radiator and be arranged on base top, said radiator are the strip fin, and said radiator is arranged on said base bottom at interval.
Preferably, said radiator and base integrated molding are made.
Preferably, said radiator is welded on said base bottom.
Preferably, said base is that the fast metal material of heat conduction is processed.
The utility model is provided with fin on the LED street lamp base, can the heat of the luminous generation of LED illuminator be distributed through fin, prolongs the service life of LED street lamp, reduces use cost.
Description of drawings
Fig. 1 is the structure sketch map of an embodiment of the utility model LED street lamp;
Fig. 2 is the Facad structure sketch map of an embodiment of the utility model LED street lamp.
The realization of the utility model purpose, functional characteristics and advantage will combine embodiment, further specify with reference to accompanying drawing.
The specific embodiment
Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
See figures.1.and.2, propose an embodiment of the LED street lamp of the utility model, this LED street lamp comprises base 10, lampshade 30, radiator, is arranged on the LED illuminator 101 and the led drive circuit on base 10 tops.Led drive circuit is connected with LED illuminator 101, and driving LED illuminator 101 is luminous.Base 10 is processed for the fast metal material of heat conduction, and lampshade 30 is connected with base 10, and lampshade 30 covers on outside the LED illuminator 101.
Said radiator is a strip fin 20, and said fin 20 is arranged on said base 10 bottoms at interval, has clearance space between the fin 20, and each fin 20 is fully contacted with air, accelerates the radiating rate of fin 20.Radiator and base 10 integrated molding manufacturings form a complete radiator structure.LED illuminator 101 produces great amount of heat when luminous, heat passes to fin 20 rapidly through the fast base 10 of heat conduction, by fin 20 heat is dispersed in the air and goes, and prolongs the service life of LED street lamp, reduces use cost.
Propose second embodiment of the LED street lamp of the utility model, the present embodiment and first embodiment are basic identical, and its main difference point is: said radiator is welded on base 10 bottoms, forms a complete radiator structure.The effect of the present embodiment and first embodiment is basic identical.
The above is merely the preferred embodiment of the utility model; Be not thus the restriction the utility model claim; Every equivalent structure transformation that utilizes the utility model specification and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the utility model.
Claims (4)
1. LED street lamp, the LED illuminator that comprises base, radiator and be arranged on base top is characterized in that, and said radiator is the strip fin, and said radiator is arranged on said base bottom at interval.
