For above content, utility model LED lamp bead in the prior art, as conventional light source, semiconductor light emitting two Polar body(LED)Heat can be also produced during operation, and the input electric energy of probably only 30-40% is converted into luminous energy, remaining 60-70% Energy it is main heat energy is converted in the form of the lattice vibration that non-radiative recombination occurs, LED heat concentrates on small-sized core In piece, chip temperature is raised, and causes non-uniform Distribution, chip light emitting efficiency and the phosphor powder lasing efficiency of thermal stress to decline;When When temperature exceedes certain value, exponentially rule increases component failure rate.Statistics shows that component temperature often rises 2 DEG C, reliability Property decline 10%.When multiple LED dense arrangements constitute white lumination system, the dissipation issues of heat are more serious.Heat is solved to dissipate Heat problem has turned into the prerequisite of high-brightness LED application.General radiating mode is transduction, three kinds of modes of convection current and radiation, LED Street lamp module section bar is typically all rectangle, and when LED lamp bead heating is given to section bar by heat transfer, section bar temperature is raised, will To radiant heat energy in air, heat can also be led out by convection current, the outside radiating surface of rectangle section bar is square, fin etc. Height influence convection current, section bar two ends fin utilization rate is not high, and radiation space is limited, and heat can not effectively shed, radiating effect one As, street lamp module shape is very single in this way, and stock utilization is not high, and cost increases.
Utility model content
To solve the deficiencies in the prior art, the purpose of this utility model is to provide a kind of equal difference stairstepping radiator street lamp Module, profile material is reduced, and area of dissipation increase, radiation space is increased, and convection space increases, and two ends fin utilization rate is raised, Module bulk temperature is more average.
In order to realize above-mentioned target, the utility model is adopted the following technical scheme that:
A kind of equal difference stairstepping radiator street lamp module, it is characterized in that, including heat sink section bar and aluminium base;The aluminium base One side be connected with the bottom surface of heat sink section bar, another side is provided with LED lamp bead;Fin is provided with the top surface of the heat sink section bar Piece, including the first fin positioned at heat sink section bar top surface two ends and the second fin directly over heat sink section bar top surface;It is described Second fin is located between the fin of both sides first;The height of the first fin described in per side is in arithmetic progression and incremental point of ecto-entad Microflute group is provided with the both sides of cloth, all first fins and the second fin;The microflute group is equidistant arrangement Several waveform sawtooths
Further, the microflute group staggering distribution of each fin both sides.
Further, the heat sink section bar two ends are provided with draw-in groove.
Further, the first fin described in every side at least includes three fins.
Further, also including sealing ring, water joint, electric wire and lens module;The water joint, heat sink section bar, Fixing hole is equipped with aluminium base, sealing ring and lens module, screw is passed sequentially through and is fixedly connected;The sealing ring is wrapped in aluminium Substrate peripheral, is engaged, it is ensured that sealing with the lens module and heat sink section bar respectively;The electric wire sequentially passes through waterproof and connects Fixing hole on head and heat sink section bar, and the center of heat sink section bar is fixed on by water joint;The lens module is provided with The lens being engaged with the LED lamp bead.
Further, four angles of the heat sink section bar bottom are provided with location hole, and four angles correspondence of lens module sets There is the locating dowel matched with the location hole.
Further, it is provided with heat-conducting silicone grease between the heat sink section bar and aluminium base.
The beneficial effect that the utility model is reached:1)Radiating fin is calculated according to time simulation effect, section bar two First fin utilization rate of side is not high and can prevent air circulation, effectively increases right using the utility model equal difference stairstepping Fluid space, the first fin utilization rate is raised, and not only solves the radiating of light fixture, and also mitigate the weight and cost of light fixture; 2)The utility model radiating fin increases fin area of dissipation using the microflute group that staggers, and effectively solves LED lamp bead heat dissipation problem, Improve the module life-span;3)When lens module is connected with heat sink section bar, assembled by locating dowel and location hole, with process is simple, The features such as lifting efficiency of assembling;4)The utility model overcomes the maintenance difficult that general street lamp brings, luminous intensity distribution illumination unevenness Deficiency, it provides a kind of radiating well, the LED street lamp module of uniform-illumination.
