Abstract
The utility model discloses a configuration high luminous efficiency LED street lamp main illuminating unit, which takes Urban Road Lighting Design Standards CJJ45-2006 as basis and takes configuration designs of improving the luminous efficiency of an LED street lamp and adjusting the luminosity curve distribution flexibly as key points, and the configuration high luminous efficiency LED street lamp main illuminating unit has expandability, maintenance and higher protection and better advantages. The main body of the illuminating unit is a special type aluminum plate with radiating flanges (2) on the back. The illuminating unit is characterized in that a line or more than one line of LED light sources is installed on the plate surface, only the luminous surface of the LED light sources is covered with a stainless steel reflecting plate (6) wholly except a part which is exposed from an LED luminotron (5), the LED light sources are combinations of LED luminotrons (5), drive circuits of the LED luminotrons and control circuits, the LED luminotrons (5) are installed on an aluminum base plate (3), the upper surface of the aluminum base plate (3) is filled with flexible silica gel (5) wholly except a part which is exposed from the an LED luminotron (5), and a screw mounting hole (1) which is used to fix an end cover is arranged on the back, and the split joint angle of a split joint surface between main illuminating units and the split joint surface between the main illuminating unit and an independent unit part can be adjustable. The adjustment of the luminous surface curvature can be realized to achieve flexible adjustment of a luminosity distribution curve.
Description
Technical field
The utility model belongs to the semiconductor lighting technology, specifically a kind of street lamp key lighting device.
Technical background
The application of led light source in street lamp become the focus of semiconductor lighting industry in recent years, it is energy-conservation, green non-pollution, long-life, can reduce maintenance and prolong the replacing time, determined its development in future than characteristics such as high color rendering index (CRI)s, all there are some roads in much big or middle city at LED street lamp on probation, does not all adopt in enormous quantities.From the technical standpoint analysis as can be seen, GB requires because low, the light distribution curve of light efficiency does not meet, the uniformity is poor, and the optical design complexity, cost is higher, maintenance difficulties is big, dispelling the heat badly causes serious or the like the problems affect of light decay it popularizes.
The street lamp of conventional light source generally all is equipped with the glass protecting cover, the glass protecting cover is owing to block the light loss that causes, the street lamp light-emitting area curvature of every kind of specification is non-adjustable, illumination uniformity is poor, the adaptive capacity of differing heights lamp stand is poor, can not adapt to the requirement of different types of road illumination standard, and maintainable poor, can not safeguarding of street lamp product damages all dismountings, integral replacing maintenance, maintenance workload is big, the maintenance cost height.
Summary of the invention
The utility model purpose is to disclose a kind of configurable high luminous efficiency LED street lamp key lighting unit, CJJ45-2006 is a foundation with " city illumination design standard ", to improve the LED road lamp efficiency, can adjust the Configuration Design that luminosity curve distributes flexibly and attach most importance to, have extensibility, maintainability, higher protection and advantage preferably.
The utility model main body is that a back is the extraordinary aluminium sheet of fin, it is characterized in that: row or the above led light source of row are housed on its plate face, the light-emitting area of led light source all is coated with the stainless steel reflector except that exposing the LED luminous tube, led light source is the combination of LED luminous tube and its drive circuit and control circuit, the LED luminous tube is installed on the aluminium base, on the aluminium base upper surface except that exposing the LED luminous tube all embeddings software silica gel, there is the fixedly screw installing hole of end cap at its back.The splicing of key lighting unit and key lighting unit and, key lighting unit and separate unit part Mosaic face, its splicing angle is adjustable.Realize the adjustable of street lamp light-emitting area curvature, reach flexible adjustment light distribution curve.
Description of drawings
Fig. 1 the utility model profile.
The specific embodiment
As shown in the figure, the utility model key lighting unit can respectively be installed a plurality of, and the light source of light fixture adopts power-type LED luminous tube 5, and the LED luminous tube is welded on the aluminium base 3 with heat sinking function, and surperficial embedding software silica gel 4, software silica gel top is provided with stainless steel reflector 6.The back is a fin 2, also is the heat abstractor of overlarge area.
The utility model advantage is:
1. there is not the glass protecting cover
This Novel LED street lamp has been abandoned conventional road lamp and the mentality of designing of LED street lamp in the past, the glass of front end The glass protective cover removes, the be up to state standards degree of protection requirement of regulation of the embedding by software silicon rubber 5. It has been reduced by the glass protecting cover block the light loss that causes, through test together with the glass protecting cover relatively Light efficiency has improved 30%.
2. has reflection unit
Be provided with stainless steel reflector 6 above the utility model light-emitting area software silicon rubber, the light that the LED luminous tube sends is except that the light intensity direction, the light of other angle and veiling glare form reflection after being radiated at the stainless steel reflector, light secondary after the reflection is got light having added on the light intensity direction again, thereby reduced light loss, improved the light utilization efficiency of LED street lamp.
3. the secondary optics of light-emitting area curvature-adjustable design
The key lighting unit trunk portion and the key lighting unit of wood utility model, installation splicing adjustable angle between key lighting unit and the key lighting unit, thereby realize the adjustable of street lamp light-emitting area curvature, reach flexible adjustment light distribution curve, solve poor, the dazzle value height of illumination uniformity, thereby improved light utilization efficiency, the adaptive capacity of raising differing heights lamp stand, the adaptive capacity of the different road types of raising.The dazzle value has possessed adjustable, to meet different pole height, different types of road illumination code requirement.The scope of application has expanded the tunnel traffic lighting field to.
4. maintainable
The utility model has solved the not maintainable of other LED street lamp product, has characteristics such as detachable, replaceable.Can fetch maintenance to fault led light source place unit replacement wherein if any fault, installation and maintenance are easy.Solved LED street lamp product integral replacing maintenance in the past, maintenance workload reduces greatly, has also reduced the maintenance cost of payment for this reason, thereby reduced the potentiality of interruption of communication.
5. super large area of dissipation
The utility model has been designed and developed aluminium section bar that upside has radiating fin as lampshade, and whole lamp body formed a big radiator structure.Because the lighter weight of aluminium and thermal conductivity factor height, can effectively internal heat be derived, therefore using aluminium section bar is better solution, when design aluminium base is tried one's best near the aluminium section bar lamp body in addition, improve radiating efficiency, thereby reduce the thermal resistance that casting glue partly produces.
