Description

A kind of barcode LED lamp

Technical field

This practicality relates to a kind of LED lamp, and is particularly related to a kind of barcode LED lamp.

Background technology

Existing illumination light-emitting principle is at fluorescent tube some special gas of packing into, coats fluorescent material at lamp tube wall, discharge during logical a last high tension electric ignition and generation light.Yet fluorescent lamp tube fractures easily, and structure is complicated, and service life is shorter, and contaminated environment, can not satisfy people's demand gradually.

For example building nightscape lighting is an emerging illumination direction, and along with China's urban landscape illumination and Tourism development, building is as important historical culture carrier and tourist quarters in the city, and the landscape value and the commercial value at its night come into one's own day by day.Also ancient building is caused irreversible damage but electric light source that generally uses in the present architectural lighting such as high-voltage gas discharging light, halogen tungsten lamp or the like are neither energy-conservation.What in the rostrum of Tian An Men roof lighting of accomplishing in 1999, use is the Par20 halogen tungsten lamp of 100W, because lamp surface temperature higher (80 ℃), light fixture is very near from glazed tiles again, causes light fixture glazed tiles on every side to be split by roasting, causes tiling to damage to some extent.Moreover, from the uv damage of electric light source, more quickened the damaged condition of architectural appearance.

(light emitting diode LED) as solid state light emitter of new generation, has numerous advantages such as long, energy-efficient, environmental protection of life-span to light emitting diode, is widely applied in demonstration, the lighting field.The spectrum of LED almost all concentrates on visible light frequency band, and its luminous efficiency can surpass 150lm/W.Diameter is that 5 millimeters white light LEDs light efficiency can surpass 150lm/W, and the life-span can be greater than 100000 hours.Someone predicts that also following LED life-span upper limit is with infinity.

Development along with the LED technology.The application of LED also more and more widely and begins to be applied in the street lamp as light emitting source.Advanced technology constantly is applied in the semiconductor production, so that the luminous efficiency of LED constantly promotes, cost continues to descend.The core of LED is a PN junction, and injected electrons and hole directly convert electric energy into luminous energy at the PN junction compound tense, but the luminous energy of not all conversion all enough is transmitted into outside the LED, and it can be absorbed and be converted into heat energy at PN junction and epoxy resin/silica gel inside.This heat energy is fatal, because can not efficiently radiates heat, the LED internal temperature is raise; Temperature is high more, and the luminous efficiency of LED is low more, and the life-span of LED is short more; Can cause the LED wafer to lose efficacy at once under the serious situation, so heat radiation is still the huge obstacle that great power LED is used.

Correlative study shows that the major failure of electronic instrument and equipment is overheated and damage that cause, and the too high meeting of temperature causes electronic instrument and the inefficacy of equipment more than 55%; And the rising exponentially that the crash rate of electronic instrument and equipment is accompanied by temperature increases; What is more, and also there are 10 ℃ of rules in some devices, i.e. 10 ℃ of the every risings of environment temperature, the crash rate of device will increase be twice above.In addition, it is emphasized that electronic instrument and equipment in concrete use, the working environment that is faced, more abominable more and various changeable than the environment under the experimental test condition certainly, that adds the influence that temperature raises, and spoilage will be higher.

On the other hand; Because the high frequency of utilization of CPU and the high-density installation of electronic equipment; How to carry out effective, three-dimensional heat radiation and just become the problem that receives much concern; This not only is related to error rate above-mentioned and spoilage, has influence on the price of commodity especially, this also be electronic instrument and equipment put into production the core that must consider.

Summary of the invention

In order to solve fractureing easily of existing lighting apparatus, structure is complicated, and service life is shorter, and contaminated environment, the problem that radiating effect is not good.A kind of barcode LED lamp is provided, comprises the Strip lighting structure that LED lamp, pcb board and heat radiation aluminum pipe constitute, it is characterized in that: the LED lamp is installed on pcb board, and pcb board is fixed on the heat radiation aluminum pipe.

Further, said Strip lighting structure which is provided with face shield.

Further, said face shield is the PC material.

Further, said LED lamp is the paster LED lamp.

Further, said pcb board is an aluminum base PCB plate heat sink.

Further, comprise copper in the material of said pcb board.

Further, said barcode LED lamp two ends are provided with plug.

Further, said Strip lighting structure comprises many, and the Strip lighting structure is connected by connector.

Further, said connector angle is 90 degree, 135 degree or 180 degree.

Further, said connector is connected with fixture.

This practical technique effect is through utilizing the LED technology, to reach long service life, the effect of environmental protection.

Be installed on pcb board through the LED lamp, pcb board is fixed on the heat radiation aluminum pipe, and said pcb board is an aluminum base PCB plate heat sink, comprises copper in the material of said pcb board and better solves heat dissipation problem.

Through the Strip lighting structure which is provided with face shield, face shield is the PC material, can prevent dazzle, and high light also can make light source become softer simultaneously, and is more comfortable.Wherein PC is a Merlon, and is lighter by 85% than other.Compare with other materials such as PETG (PET) and polypropylene (PP), polyvinyl chloride (PVC), have good hardness, toughness, break resistance and heat-resisting quantity concurrently, can guarantee longer service life.

Be provided with plug through barcode LED lamp two ends, join and make dress, can play fixation for finishing.

Comprise many through said Strip lighting structure, the Strip lighting structure is connected by connector, and the connector angle is 90 degree, 135 degree or 180 degree, and connector is connected with fixture, and multiple environment can be provided.

This is simple in structure, is convenient to install and use, sharp with apply.
