Description
Technical field
The invention belongs to field of LED illumination, relate to a kind of LED street lamp.
Background technology
The radiator of existing integrated LED road lamp is all an integrated radiator, radiator body wall is provided with elongated electric pole fixing hole, constant-current supply holding tank, in order to cooling requirements, also some radiating fins are set in the above, its wall thickness, volume is large, Heavy Weight, need aluminium many, cost is high, outdoor high-altitude is installed inconvenient, high to the requirement of strength of lamp stand.Radiator only forms cross-ventilation in the gap of radiating fin, and whole main wall does not then have, so its radiating effect is poor, the light decay of LED is large, reduces the service life of LED street lamp.Lamp wall diameter due to common lamp stand has 50mm and 60mm two kinds of specifications, match to make the lamp stand of elongated electric pole fixing hole and two kinds of specifications, the mould making two kinds of specification radiators must be had, make the radiator of two kinds of specifications, to meet the demand of client, this not only adds cost of manufacture, and take memory space, in order to address this problem, people are generally the radiators only doing 60mm electric pole fixing hole, when lamp stand is 50mm, just need to strengthen fixing bolt and cushioning pad, to reach the stability of installation, not only waste time and energy, and steadiness or very poor.In present light fixture market, because the price of LED lamp, volume and weight are all far away higher than other light fixtures such as sodium vapor lamp, Metal halogen lamp and mercury lamps, so it promotes the use of very difficult, reduce the cost of LED lamp, increasing its radiating effect is the problem that LED lamp is forever studied.
Summary of the invention
Object of the present invention solves the above-mentioned problems in the prior art exactly, provide a kind of Modular LED street lamp, its radiator considerably increases area of dissipation under the limited volume that takes up room, and it is lightweight, consumptive material is few, cost is low, the light decay of good heat dissipation effect, LED significantly reduces.
For achieving the above object, technical solution of the present invention is: a kind of Modular LED street lamp, it comprise metal heat sink, two heat dissipation metal arms, one, two or more LED module, fixed dam, rear middle baffle plate, be fixed on rear sleeve on lamp stand and backboard; Each LED module comprises multiple great power LED, fixing aluminum-based circuit board, the reflector peace diffuser be connected with by each LED electrical; Aluminum-based circuit board is fixed on radiator bottom surface, and reflector to cover on LED and is plugged in aluminum-based circuit board; Flat diffuser covers on outside reflector, and its inner surface presses close to reflector, and edge is fixed on radiator bottom surface by the sealing gasket of crimping; Bottom surface has cable-through hole with radiator, and stifled on cable-through hole have sealing-plug; Radiator bottom surface is planar sheet, have multiple radiating fin above, the middle cavity between radiating fin is power storehouse, and constant-current supply is fixed on power supply liner plate, power supply liner plate is fixed on the radiating fin of power storehouse bottom surface, and power storehouse lid is fixed on the radiating fin of both sides, power storehouse upper surface; Radiator both sides are connected in two heat radiation arms respectively, and its front end is fixed on two heat radiation arms by rear middle baffle plate and rear sleeve extruding by fixed dam, rear end successively; The both sides clamping of fixed dam and rear sleeve is also fixed in two heat radiation arms, and rear middle baffle plate is connected in two heat radiation arms; There is the rear overhead gage being connected to two heat radiation arm upper ends rear sleeve upper end, and there is the rear lower baffle plate being connected to two heat radiation arm lower ends its lower end; Backboard is fixed on the rear end face of two heat radiation arms, rear overhead gage, rear sleeve and rear lower baffle plate; Rear lower baffle plate has vent window B; The cylindrical central sleeve of rear sleeve is lamp stand fixing hole, backboard has lamp stand via hole; Rear middle baffle plate has vent window A.
The present invention also comprises front apron and front middle baffle plate; Described fixed dam is identical with the structure of rear sleeve, and just it is shorter than rear sleeve, the front overhead gage that its upper end has the structure that is connected to two heat radiation arm upper ends identical with rear overhead gage, and there is the front lower baffle plate being connected to two heat radiation arm lower ends its lower end; Front middle baffle plate is identical with the structure of backboard with rear middle baffle plate with front apron, and front middle baffle plate is connected in two heat radiation arms, and front apron is fixed on the front end face of two heat radiation arms, front overhead gage, fixed dam and front lower baffle plate.Such design, can reduce number of molds, saves die cost, reduces the production cost of LED street lamp.
The present invention also comprises streamlined front decoration cap and rear decoction cap; Front decoration cap is directly fixed on fixed dam or snaps onto the outer rim of front apron and be fixed on fixed dam; Rear decoction cap snaps onto the outer rim of backboard and is fixed on rear sleeve, rear decoction cap has lamp stand via hole.Front decoration cap and rear decoction cap increase aesthetics of the present invention, have well blocked dust and have entered in heat dissipation channel; Streamlined front decoration cap reduces windage.
The dual-side lower end of power storehouse lid described above is stuck in the buckling groove of the radiating fin of both sides, power storehouse upper end.
The present invention adopts LED module form, can according to the needs of lamp power design actual LED module number, assembling is flexible.Adopt the form that radiator and heat radiation arm separately design, power storehouse design is between radiating fin, it greatly reduces the volume of radiator body wall, it is made to become one, bottom surface thin plate, it considerably increases area of dissipation under the limited volume that takes up room, and the alleviating of the reduction of amassing due to radiator body wall body and weight, it also just only becomes rear sleeve of the present invention by the original elongated electric pole fixing hole arranged on main wall, also further reduces the volume and weight of radiator body wall.Because lamp stand is only fixed by rear sleeve, so as long as change the rear sleeve of different inner diameter, just can match with the lamp stand of two kinds of different sizes, then the die cost of sleeve is low, and the volume taken is little.The radiating fin of radiator, fixed dam, rear middle baffle plate and rear sleeve form cavity structure from A-P, define multiple air channel, air is introduced by the vent window B below rear lower baffle plate, increase rate of air circulation, in the air exchanging in cavity that the heat that radiator is derived can be very fast, be dispersed in the air with air, radiating effect of the present invention is better, make whole light temperature can not be very high, reduce the light decay of LED, extend the service life of LED.When the parts such as radiator, heat radiation arm, fixed dam, rear sleeve, forward and backward overhead gage and forward and backward lower baffle plate adopt aluminium alloy to make, can drawing and forming, its mechanical strength is high, entirety is thin-wall construction, intercept according to the length used again, greatly reduce the die cost making each parts, and manufacture craft is simple, cost of manufacture reduces greatly.Rear lower baffle plate also has the effect of leaking, and front decoration cap and rear decoction cap have blocked dust and entered in heat dissipation channel.
In a word, the present invention assembles flexibly and easily, and radiator considerably increases area of dissipation under the limited volume that takes up room, lightweight, consumptive material is few, cost is low, the light decay of good heat dissipation effect, LED significantly reduces, and its dust-proof effect is also fine.
