Description

LED light fixture with front/back cavity structure
Technical field
The present invention is a kind of LED light fixture, and particularly a kind of LED light fixture with front/back cavity structure belongs to the lighting device technical field.
Background technology
Street lamp is the important component part of city illumination, is extensive use of in road lightings such as city expressway, trunk roads, secondary distributor road, branch road, factory, school, gardens, various residential quarters, garden.The street lamp that generally uses mostly is common incandescent lamp and high-pressure mercury lamp now, and power is all at 150W-400W, and light efficiency is low on the whole, has caused the huge waste of the energy; And conventional road lamp can only normally use under electric power provides sufficient situation, and conventional road lamp very easily damages fluorescent tube when being lower than rated power work.The LED street lamp is because of advantages such as it is new and effective, energy-conservation, the life-span is long, colour rendering index is high, environmental protection in recent years, and development is rapid at home, and market scale is constantly extended.But its heat dissipation problem is rationally solved all the time.The LED light fixture, the Chang Zuowei street lamp is installed in the high-altitude, and inconvenience arranges the attached heat abstractors that help such as fan, and its radiating mode mainly relies on Natural Heat Convection, just will pass through the LED aluminium base, is transmitted to the fin of shell of lamp base, diffuses in the air again.Like this, by the natural heat-transfer rate of LED aluminium base to shell of lamp base, the radiating effect of LED light fixture will be determined.The common LED lamp tool tend to because of the flatness of shell of lamp base too low, cause when LED aluminium base and shell of lamp base installation, using heat-conducting silicone grease, fill and lead up its installed surface, but through using after a while, the dry cracking thereby heat-conducting silicone grease can become, this moment, heat-conducting silicone grease just became the thermal resistance material, can cause the heat on the LED aluminium base can't be transmitted on the shell of lamp base, can't dispel the heat at last.Traditional LED light fixture can be installed in power supply the upper position of fin usually; make the big thermal source of 2 in the LED light fixture; be that the stack of LED aluminium base and power supply arranges; power supply is laminated on the upper position of the fin of LED aluminium base; such structure can cause the thermal source undue concentration, causes effectively heat loss through convection.
In addition, because the LED street lamp mostly is to be erected on the electric pole, sleet is often arranged, in case water inlet is easy to cause damage in the lamp, produces serious consequence, so just need often overhaul, safeguard and change, bring inconvenience, waste a large amount of financial resources, material resources; The electric power incoming line connection is insecure, needs often maintenance, when being used for street lamp, and the work high above the ground of maintenance palpus, very inconvenient.And, under the situation that the electric power incoming line thickness changes, be not easy to connect; Moreover common LED light fixture and connecting rod connection angle are fixed, and inconvenience is regulated, and as street lamp, during night illumination, in different mounting distances, different setting height(from bottom)s, just can not reach optimal illuminating effect like this; At last, a bit be in addition, former electric power incoming line connection is insecure, needs often maintenance, when being used for street lamp, and the work high above the ground of maintenance palpus, very inconvenient.And, under the situation that the electric power incoming line thickness changes, be not easy to connect.
Summary of the invention
The objective of the invention is in the above-mentioned prior art, because of the flatness of shell of lamp base too low, use heat-conducting silicone grease, easy season cracking, and LED aluminium base and power supply stack setting, cause effectively heat loss through convection, often there is sleet to infiltrate lamp interior, cause the light fixture rapid wear, LED light fixture and the inconvenience of connecting rod connection angle are regulated, and can not reach optimal illuminating effect, and electric power incoming line connects insecure, the defective that is not easy to connect, provide a kind of have before, the LED light fixture of back cavity configuration can make thermal source disperse to arrange, and produces effective heat loss through convection, shorten heat conducting distance, increased the radiating efficiency of fin; Can prevent effectively that sleet from infiltrating lamp interior, avoids the light fixture rapid wear; Make connection angle be convenient to regulate, can reach optimal illuminating effect; Can guarantee electric power incoming line, no matter thickness all can be connected firmly, not need frequent maintenance.
