Description
Technical field
The present invention relates to technical field of lamps, be specifically related to a kind of long-life street lamp.
Background technology
Traditional High-Pole Lamp, its light source adopts powerful mercury vapor lamp, Metal halogen lamp or high-pressure mercury lamp etc. mostly, in its light source, mostly contain hazardous substance, easily cause environmental pollution, and the thick heaviness of the lamp holder of making, power consumption is large, maintenance cost is high, illuminating effect is all unsatisfactory at aspects such as colour rendering and anti-dazzle performances.Meanwhile, the development of semiconductor light sources light emitting diode (LED) is but very rapid, and in recent years, the luminous efficiency of part LED has substantially exceeded incandescent lamp, even exceedes the luminous efficiency of fluorescent lamp.Compared with traditional Projecting Lamp electric light source, the basic nonhazardous of LED light source, no electromagnetic pollution and have that volume is little, energy consumption is low, light efficiency is high, caloric value is relatively low and many-sided advantage such as long service life, can substitute conventional light source and make High-Pole Lamp.Consider single chip LED luminosity deficiency, LED light fixture generally adopts LED array formula structure, has produced thus that LED light fixture heat is concentrated, local temperature is too high, causes light decay aggravation, thereby affect the normal use of LED, causes reduction in service life.At present, power type white light LED can only be luminous energy by approximately 15% electric energy conversion, and remaining 85% energy changes into heat energy.Along with the increase of LED power, quantity of heat production increases, and bad if heat dissipation problem solves, heat concentrates in small-sized chip, makes chip internal temperature more and more higher.The too high meeting of chip temperature brings many problems, as accelerated device aging, accelerates the speed of LED light decay, reduction of service life, even also can cause chip to burn; How effectively solve heat radiation and prevent that chip from burning, become and high-powerly face problem the most in the urgent need to address at LED light fixture.
For this reason, High-Pole Lamp is provided with passage, to accelerate circulation of air, improves radiating effect.But because High-Pole Lamp is to be all used in open air mostly; as city square, station, harbour, goods yard, highway, stadium, viaduct etc.; so this High-Pole Lamp often can be drenched with rain; rainwater easily enters in High-Pole Lamp from passage; cause its damage rate quite high; reduction of service life, but also there will be leaky, exist potential safety hazard.
Summary of the invention
The object of the invention is to, for above-mentioned deficiency, a kind of rational in infrastructure, good water-proof effect is provided and prevents excess Temperature, the long-life street lamp of effectively avoiding chip to burn.
For achieving the above object, technical scheme provided by the present invention is:
A kind of long-life street lamp, it comprises lamp body, water-proof ventilated device, power supply unit, illuminating module and attemperating unit, the bottom surface of this lamp body is provided with one and is used for installing the annular seal space of described illuminating module, sealing chamber is provided with one and is used for the water-proof ventilated device that its inner space is connected with space outerpace, described illuminating module is inserted sealing chamber, described power supply unit is arranged on the end face of lamp body, described attemperating unit is arranged in illuminating module, and can carry out the corresponding circuit that power supply unit is connected with illuminating module that is switched on or switched off according to predefined temperature.
Described illuminating module comprises a circuit board and multiple LED lamp being evenly arranged on this circuit board.
Described attemperating unit is arranged on described circuit board.
The upper end of described water-proof ventilated device is fixed on the end face of described lamp body, and this lamp body is run through in lower end, and stretches into described annular seal space.
Open Side Down for described annular seal space, and be provided with a transparent cover body on this opening.
On described lamp body, establish an installing rack.Convenient for assembly, easy to use.
Beneficial effect of the present invention is: the present invention designs ingenious reasonable, be provided with water-proof ventilated device, ensureing circulation of air, on the basis of raising radiating effect, improve sealing property, effectively guarantee the good water-proof effect of product, not only improved safe class and degree of protection, ensured security performance, also expand its scope of application, be applicable to outdoor and overcast and rainy; And be provided with attemperating unit, effectively prevent that chip or other part from, because excess Temperature damages, burns, increasing the service life greatly.
Below in conjunction with accompanying drawing and embodiment, the present invention is further described.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the decomposition texture schematic diagram of Fig. 1;
Fig. 3 is the A-A sectional structure schematic diagram of Fig. 1.
Detailed description of the invention
Embodiment: referring to Fig. 1 to Fig. 3, a kind of long-life street lamp that the present embodiment provides, it comprises lamp body 1, water-proof ventilated device 2, power supply unit 3, illuminating module 4 and attemperating unit 5, the bottom surface of this lamp body 1 is provided with one and is used for installing the annular seal space of described illuminating module 4, sealing chamber is provided with one and is used for the water-proof ventilated device 2 that its inner space is connected with space outerpace, described illuminating module 4 is inserted sealing chamber, described power supply unit 3 is arranged on the end face of lamp body 1, described attemperating unit 5 is arranged in illuminating module 4, and can carry out the corresponding circuit that power supply unit 3 is connected with illuminating module 4 that is switched on or switched off according to predefined temperature.
Described illuminating module 4 comprises a circuit board 41 and multiple LED lamp 42 being evenly arranged on this circuit board 41.
