Abstract

The utility model relates to an LED street lamp and belongs to the technical field of semiconductor illumination. The LED street lamp of the prior art uses a structure of an integrated undetectable light source so the whole lamp is exchanged if the LED is damaged, and the dust is easily accumulated on the radiating fins arranged on the upper surface of the lamp so the lamp has inferior radiating property. The utility model divides a light source into a plurality of modules; the modules can be provided with an individual power supply module and also can share one power supply module; each module comprises a radiator and an LED element in the radiator which are arranged on one plate and placed in the lamp shell; and the radiator is placed on the lower part of the lamp shell so the dust is prevented from accumulating, the radiating property is long-term stable, the reliability and service life of the lamp are promoted, and the modularized structure is beneficial to maintain the street lamp conveniently. When some illuminating modules are not lighted, the modules can be exchanged easily like exchanging common bulb of the street lamp.

Description

A kind of LED street lamp

Technical field

The utility model relates to lighting field, is specifically related to technical field of semiconductor illumination.

Background technology

Technical field of semiconductor illumination had obtained very big progress in recent years, the LED street lamp product of existing many producers comes out, two big class formations are arranged usually: a kind of is to adopt the IW high-power LED luminescent part, the street lamp of 100W will use 100 1W LED, generally be that these LEDs up to a hundred are mounted on the aluminium alloy heat radiator, the upper surface of light fixture is furnished with radiating fin; Another kind is to use super high power encapsulated LED element, for example with tens watts, go up that the LED of hectowatt is integrated to be encapsulated in one, again it is mounted on the aluminium alloy heat radiator.Though this class formation respectively has its advantage, but two common shortcomings are arranged: one is exactly in case break down, repair pretty troublesome, because whole light fixture is a closed structure, must put in order the lamp dismounting and change, and existing high-pressure mercury lamp street lamp bulb has been broken as long as bulb of replacing is just passable, comparing to seem that maintenance is more simple and convenient.It two is exactly that the upper surface of radiator lamp housing accumulates dust easily, this will make the heat dispersion of light fixture have a greatly reduced quality, remove laying dust, can only rely on the strength of wind and rain, but the dust in the reality on the highway is bigger, but within these few days with regard to energy product last layer dust, is to reach some months just once sometimes and rain, it is insecure that the wind and rain strength that therefore will rely on nature cleans radiator, and yes ensures on structural design for best method.Self-evident, after the heat dispersion of radiator descends,, directly cause light efficiency to reduce with causing the junction temperature of led chip to raise, light decay quickens, and the working life of LED shortens.

Summary of the invention

Goal of the invention

The utility model proposes a kind of new LED lamp post structure design, purpose is to improve two big shortcomings of aforementioned existing LED street lamp, make that promptly the maintenance abnormality of LED street lamp is easy, can effectively avoid radiator to accumulate dust again and influence heat dispersion, also increased by a big advantage simultaneously, improved the reliability of street lamp exactly.

The technical solution of the utility model is: the light source of street lamp is resolved into by several form to dozens of LED light emitting module combination of components, the formation of each light emitting module assembly can have four kinds of infrastructure mode again, first light emitting module assembly is by aluminium alloy heat radiator and LED light-emitting component in it is installed and lamp holder and interior power module and screw lamp holder thereof constitute, all lamp sockets be installed in one straight or have on the plate of bending and place lamp housing again, the assembly of being made up of radiator and inner LED element and lamp holder and internal electric source module is actually a Lamp cup (or claiming bulb) assembly, can screw in easily and be installed on the lamp socket, all the power line of lamp sockets is connected on the power bus.Second kind of tactic pattern is that the power module in each lamp holder in preceding a kind of tactic pattern is removed, the power line of whole lamp sockets is connected with the output of a common source module, perhaps the power line of several lamp sockets is connected to a component light source of the whole lamp of output formation of a power module, and the fractions combination of light sources becomes whole lamp source.The light emitting module assembly of the third tactic pattern is made of aluminium alloy heat radiator and LED light-emitting component and the power module installed in it, promptly be that lamp holder and lamp socket in first kind of structure are removed, directly the light emitting module assembly is installed in one straight or have on the plate of bending, place lamp housing again, the power input line of each power module is connected on the power bus.The light emitting module assembly of the 4th kind of tactic pattern is made of aluminium alloy heat radiator and the LED light-emitting component installed in it, all the light emitting module assemblies be installed in one straight or have on the plate of bending, place lamp housing again, all the power input line of light emitting module assembly is connected to the output of common source module, perhaps the power input line of several light emitting module assemblies is connected to a component light source of the whole lamp of output formation of a power module, and the fractions combination of light sources becomes whole lamp source.

The circuit front-end of above-mentioned various tactic patterns all can insert a controller for road lamp, this controller has the timed power mapping function, for example make street lamp in the first half of the night the period total power turn on light, later half-power is after midnight turned on light in the time of zero, reaches energy-conservation to greatest extent purpose.Because the utility model scheme makes the road-light light-source module combinationsization, make and realize the easier design of this control function, first and the third structure in, the power input line of each module can be divided into the control output end that two or more sets lines are connected to controller for road lamp; Second and the 4th kind of structure in, the power supply input that available controller is controlled each component light source realizes the time-sharing automatic control of timing of street lamp power.Aluminium alloy heat radiator in above-mentioned each scheme can be made by extrusion process or extrusion process, and sensing of fin should be adopted direction vertically on it, and favourable heat radiation like this and minimizing dust stockpile; The metal shell that also available extrusion process of streetlamp housing or extrusion process or Sheet Metal Forming Technology are made; Said lamp holder and lamp socket in the scheme should be selected the screw socket and the lamp socket of existing standard for use.

Technique effect

After street lamp adopts technical solutions of the utility model, light source is by module combinationsization, generally, if have only one, two module lamp not work, illumination influence to road is little, can change module when by the time three, four module damage being arranged again regardless of it, and it is easy just as changing a bulb to change module, and this has just significantly reduced maintenance workload.Aluminium alloy heat radiator in the aforementioned approaches case all is in the bottom of lamp housing, fin is that direction is arranged vertically, both helped cold-hot air convection exchange heat radiation, can not make fin surface accumulate dust again, it is very little to keep heat dispersion to change for a long time, more than these characteristics all help to improve the reliability and the useful working life of street lamp.
