Description
Technical field
The utility model belongs to lighting technical field, particularly relates to a kind of LED street lamp parts, can be used for consisting of the LED street lamp.
Background technology
The LED light fixture is compared with tradition such as high-pressure mercury lamp, incandescent lamps: the 100-120WLED street lamp can replace the 250W high-pressure mercury lamp, energy-conservationly reach more than 50%, free from glare, without stroboscopic.Eliminate caused dazzling, the visual fatigue of common street lamp dazzle and sight line and disturbed, improved the security of driving.The pollution elements such as not leaded, mercury, to environment without any pollution, the theoretical life-span of LED is more than 100,000 hours because its heating reduces service life, the LED life-span of at present industry design, its life-span was more than 3 times of conventional road lamp about 3000-50000 hour.Except above energy-conserving and environment-protective, beyond the advantages such as long-life, LED street lamp volume is little, is convenient to Design of Luminaires, uses low voltage operating, utilize Based Intelligent Control, easy to maintenance etc., and performance improves constantly, cost constantly reduces.So the LED light fixture will progressively replace conventional lamp in fields such as road lighting, commercial lighting, Landscape Lightings as main illuminating product.For the LED road lighting, what at present light fixture was commonly used is integrated design, and more difficult target heat flux road, luminous intensity distribution is inhomogeneous, protection is bad etc., follow-up maintenance difficulty especially, and cost is high.So the modularity design is the main flow of present LED road illuminating lamp design.
The street lamp module that prior art proposes, the single socket of its lens LED, installation step is various, and cost is higher.Adopt heat pipe, hot plate, LHP(loop hot-pipe) etc. the heat outlet parts auxiliary heat conduction, long apart from heat conduction but these parts only provide, can not really play the effect of heat radiation, increased on the contrary product cost.The practical fan cooling that also has, although radiating effect is good, the fan reliability is low, and cost is high, and the life-span is short, and these schemes are not preferred plan.
For the deficiencies in the prior art, the utility model patent proposes a kind of good heat dissipation effect, LED road lamp cooling module with low cost.
Summary of the invention
The purpose of this utility model is to solve deficiency of the prior art, and a kind of LED street lamp module is provided, and to improve the heat-sinking capability of LED street lamp, reduces its cost, improves the service life of street lamp.
For achieving the above object, LED street lamp module of the present utility model comprises radiator, pcb board, led light source, lens carrier and lens; Wherein radiator adopts aluminium section bar, and one-body molded by mould, the cooling fin array forms sector structure by a plurality of convex tendons.
Through injection molded, lens carrier simultaneously is provided with lens to above-mentioned lens carrier by transparent plastic, and another side is provided with groove.
Compared with the prior art, the utlity model has following advantage:
1, because fansink designs has the cooling fin array, its surface is provided with a plurality of convex tendons, has increased area of dissipation.
2, between led light source and pcb board and radiator, adopt heat-conducting silicone grease to fill, increased the assistance capacity of heat transmission of radiator.
3, lens are arranged on the lens carrier, and convenient, light fixture Reliability Enhancement is installed.
Description of drawings
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is the floor map after pcb board of the present utility model and lens carrier are installed.
The specific embodiment:
See figures.1.and.2, a kind of Modular LED road lamp of the utility model comprises: radiator 1, pcb board 2, led light source 3, lens carrier 4 and lens 5 form; The one side of radiator 1 is provided with cooling fin array 7, and this cooling fin array 7 forms sector structure by a plurality of convex tendons 8, saves the use amount of aluminium section bar, and another side is connected with lens by pcb board 2 and led light source 3, lens carrier 4 and is connected successively.The radiator 1 whole aluminium section bar that uses forms by the aluminium agent, cuts according to required width.Through injection molded, lens carrier simultaneously is provided with the first groove 9 and the second groove 10 to lens carrier 4 by transparent plastic, and this second groove 10 is arranged on the peripheral edge of lens carrier 4, and lens (5) are arranged on the another side of lens carrier (4).The light that lens 5 can send led light source is bat aerofoil profile or rectangular light spot through secondary light-distribution, reaches the road lighting effect.Led light source 3 is welded on the pcb board 2, and pcb board 2 places in the first groove 9 of lens carrier 4; The second groove 10 of lens carrier 4 is equipped with waterproof adhesive tape 6; Lens carrier 4, pcb board 2 and radiator 1 tightly lock together by screw.Being filled with heat-conducting silicone grease between radiator 1, pcb board 2 and the led light source 3 has increased the assistance capacity of heat transmission of radiator.
