Description

A kind of LED street lamp
Technical field
The utility model relates to a kind of LED street lamp; Particularly a kind of Switching Power Supply that need not heavy metal heat sink, need not expensive poor efficiency, and the Novel LED street lamp that luminous efficiency is high, cost is low, in light weight and maintenance can more change the bulb at the scene to be accomplished; Alternative high-pressure mercury lamp, Metal halogen lamp etc. are used for illuminations such as road, tunnel and square.
Background technology
The LED street lamp of prior art generally is to make light source with the power-type LED of a plurality of low-voltage and high-current power-type LEDs or the integrated encapsulation of much power LED chips; Led chip is installed in heat-conducting glue on the metal-base circuit plate (MPCB) through LED is heat sink, is installed in MPCB on the metal heat sink that has a fin with heat-conducting glue again; The driver of its LED is for changing the high-voltage alternating civil power into the Switching Power Supply and the constant-current circuit of low-voltage, high-current.
The LED street lamp principal character of prior art is: low-voltage, high-current LED adds MPCB and adds metal heat sink.
The LED street lamp needs very high output light flux as illuminations such as roads; Its input electric power is tens to several hectowatts; So big electrical power concentrate on one with several small sizes heat sink on; Again through MPCB, heat-conducting glue and radiator heat-dissipation; How to reduce chip to heat sink, to the thermal resistance of radiator with improve the radiating effect of radiator, the temperature of the P-N knot when making LED work can not rise De Taigao, guaranteeing its service life and reliability, this problem, just be one of difficult problem of this type street lamp from being born from this type street lamp always.LED is a semiconductor devices; If heat radiation is bad, junction temperature is too high; Then can seriously reduce its luminous efficiency, service life and reliability, also can cause luminescent material, transparent medium and the adhesive material of LED rotten simultaneously, cause serious problems such as LED street lamp light decay is serious, reliability is low.
In order to solve the heat dissipation problem of LED, the LED street lamp of prior art generally adopts a metal heat sink or a flowing water type curved surface aluminium heat sink that has fin, and for example Chinese patent 200610070282.8; 200880023284.9; 200920171258.2, United States Patent (USP) 7637637,7637633; And for example EP2360422 is that great power LED adds PCB and adds the heat dissipation metal cover; These all belong to same type of great power LED and add the street lamp that PCB adds metal heat sink.For better heat radiating effect is arranged, said radiator needs enough big area of dissipation and volume, and said radiator is generally processed by the high thermal conductivity aluminium alloy, and volume is big, Heavy Weight, cost are high, need to consume a large amount of aluminum metal resources.Even but like this, the light decay of its LED is still very serious, remains one of difficulty that present LED street lamp promotes.
The flange-cooled radiator of this type must be exposed in the air; And that street lamp is operated in throughout the year is outdoor; The fin of radiator deposits dust, birds droppings etc. easily, causes the radiator heat-dissipation effect to descend even inefficacy, thus the light decay of aggravation LED and the life-span that shortens street lamp.
For the radiating effect and saving aluminium consumption that improves radiator, developed the radiator of a kind of " penetrating up and down " and " three-dimensional (3D) heat radiation " recently, for example Chinese patent 200810204172.5 and 201010118280.8; But still be difficult to thoroughly solve above-mentioned difficulties.
Secondly; The maintenance trouble of this type LED street lamp; Need unload the whole LED road lamp cap, transport back down depot level maintenance; This only needs more change the bulb at the scene with high-intensity gas discharge lamp (HID) such as existing high-pressure mercury lamp and compares, maintenance cost is so high, and this is another difficult problem that present LED street lamp is promoted.
In addition, the power-type LED of the LED street lamp of prior art is the low-voltage, high-current device, needs a high voltage electric main to be transformed into the driver of low-voltage, high-current; It is made up of a Switching Power Supply and constant-current circuit, because the voltage difference of its input and output is big, the conversion efficiency of said driver is low; Generally only about 85%; It has elements such as triode, transformer and electrochemical capacitor simultaneously, and cost is high, poor reliability, life-span weak point.The cost height is the another difficult problem that existing LED street lamp is promoted.
Moreover, the street lamp multipurpose high-pressure sodium vapor lamp of prior art, its luminous efficiency more has to reach 140lm/W's up to 120lm/W.And the whole lamp efficient of existing LED street lamp is generally all less than 90lm/W.
In sum, deficiencies such as existing LED street lamp exists that cost height, luminous efficiency are low, Heavy Weight, poor reliability, light decay are big, maintenance trouble also are difficult to extensive popularization at present, are badly in need of a kind of Novel LED street lamp that can thoroughly overcome above-mentioned deficiency.
Summary of the invention
