Description

The LED street lamp of band lens

Technical field

The utility model belongs to the technical field of LED street lamp, refers in particular to a kind of LED street lamp with lens.

Background technology

Traditional street lamp generally adopts sodium vapor lamp, mercury lamp or halogen lamp, and this light fixture has many shortcomings such as consumed power is big, maintenance cost is high, pollution is big, life of product is short.Along with progress of science and technology, The development in society and economy, it is found that, the characteristics of led light source are: energy-conservation, security is good, volume is little, life-span is long, response time is fast, no poisonous metal mercury is to pollution of environment etc., Application and Development along with high-powered LED lamp, the LED lamp develops from the direction of spot light to functional illumination, be progressively to replace traditional sodium vapor lamp, the renewal product of mercury lamp or halogen lamp, at present, the product of existing LED lamp is applied to the example of street lamp, yet, since the structure of product and optical principle utilize the lamp problem, form the overlapping hot spot that waits in light area of adjacent street lamp, the scattering of light angle is too big, the waste electric energy, in addition, because street lamp is after partial L ED lamp damages, because its lumen does not reach designing requirement, generally whole street lamp will be changed, make to also have most of fair LED lamps to scrap thereupon, the maintenance cost height, resource utilization is low.

Summary of the invention

The purpose of this utility model provides the LED street lamp of the band lens that a kind of maintenance cost is low, the light area good, the efficiency of light energy utilization is high.

The purpose of this utility model is achieved in that

The LED street lamp of band lens, be connected with cover in arch on the top of front and back connector, the left and right sides is connected with left end cap and right end cap respectively, the middle part is plugged with the downward LED lamp module of illumination direction more than, top at side of front and back connector and the end cap that links to each other with this side is provided with the lamp stand support, described LED lamp module is: be provided with some LED lamps in it, each LED lamp is provided with lens, all lens are fixed on the radiator that has fin by the cover that can expose lens, between lens and cover, be provided with sealing ring, be connected with plug after the electric connection line parallel connection of all LED lamp modules.

Above-mentioned lamp stand support is: be provided with the arc connecting plate of downward arch in the bottom to the arc that arches up on rack body top, be connected with bolt in the both sides of arc with the arc connecting plate, be connected with trim on the top of lamp stand support.

The structure of above-mentioned lens is: the top of lens outer surface and side are the astigmatic projection that is pillow shape, and the bottom is a plane, extend outward in the outer on plane the limit is installed, and are provided with the recessed semi-circular hole that makes progress at the middle part on plane.

The outstanding compared to existing technology advantage of the utility model is:

1, be convenient to clean: glass lens of the present utility model covers the outer surface of the field of illumination of LED lamp module, because good airproof performance is convenient to clean, can keep the illumination brightness that designs;

2, maintainability is good: LED lamp module of the present utility model is pick-and-place components independently, and a LED lamp module damages, and can change the LED lamp module of this damage separately, and whole street lamp is worked on, and easy to maintenance, maintenance cost is low, long service life;

3, the light area is good: lens of the present utility model can distribute the preferably illumination range and the zone of each LED lamp monomer, and make light concentrate the zone that is distributed in design, save luminous energy, luminous spot is few.
