Description

The LED street lamp
Technical field:
The utility model relates to a kind of LED street lamp.
Background technology:
Most on the market LED street lamps adopt the die casting aluminium shell, because the great power LED heat is concentrated, only rely on the heat conductivility of aluminium that heat is evenly distributed on the radiator, cause heat can not smooth and easyly be dispersed into surrounding environment thus, so shorten the service life of entire product.
Perhaps adopt big shell radiator, will greatly increase product weight, weigh more than 40% and just can reach equal radiating effect if adopt the die casting aluminium shell to take charge of product than me with power product.
Also have partial L ED street lamp to adopt the conventional road lamp shell, heat is concentrated can't distribute, and the temperature rise of LED internal junction will be shortened the service life of lamp pearl greatly.
The utility model content:
Technical problem to be solved in the utility model is to overcome existing above-mentioned deficiency in the prior art, and a kind of good heat dissipation effect, intensity height, LED street lamp that the dustproof and waterproof performance is good are provided.
The technical scheme in the invention for solving the above technical problem is: this LED street lamp, it is characterized in that comprising shell, loam cake, lens, first sealing gasket, the LED module, heat conductive pad, base plate, fasten fin, heat pipe, enclosing cover, second sealing gasket, base plate, fasten fin, heat pipe is installed together, heat conductive pad is attached to the LED module back side and is fixed on the base plate, first sealing gasket is installed in the lens back side, lens are installed on the base plate, shell is fixedlyed connected with base plate, power supply, the constant current plate is fixed on the shell, second sealing gasket is fixed in the body seal groove, loam cake is fixedlyed connected with shell, and enclosing cover is fixed on the shell.
The utlity model has characteristics such as good heat dissipation effect, intensity height, dustproof and waterproof performance be good, simple in structure and highly effective.
Description of drawings:
Fig. 1 is the exploded perspective view of the utility model embodiment.
The specific embodiment:
Referring to Fig. 1, the utility model embodiment comprises shell 1, loam cake 2, lens 3, first sealing gasket 4, LED module 5, heat conductive pad 6, base plate 7, fastens fin 8, heat pipe 9, enclosing cover 10, second sealing gasket 11, silicone tube 12, briquetting 13, pipe joint 14, power supply, constant current plate, at first adopts welding procedures to make a heat radiation module heat pipe 9, fastening fin 8, base plate 7.
Then heat conductive pad 6 is attached to LED module 5 back sides, is locked on the heat radiation module base plate 7 with 17 screws.
Again first sealing gasket 4 is installed in lens 3 back sides, both are locked on the heat radiation module base plate 7 with 10 screws.
Again entire module is locked on the shell 1 with screw.
Again power supply, constant current plate are fixed on the shell 1 with screw, again second sealing gasket, 11 usefulness glue are bonded in the seal groove, cover loam cake 2, lock screw.
At last enclosing cover 10 usefulness screws are fixed on the shell 1, whole light fixture assembling promptly finishes.
The utlity model has following characteristics:
1, adopts advanced heat pipe for thermal conductivity technology, heat pipe 9 is imbedded in the base plate 7, be placed in LED just above, push down heat pipe 9 with briquetting 13, the heat that LED is distributed is distributed to rapidly on the fin by the heat pipe 9 powerful capacity of heat transmission, by the free convection effect heat is dispersed in the surrounding environment again.
2, adopt fastening fin 8 to make whole fin be linked to be an integral body, make product have better intensity and optimization heat radiation spacing.
3, adopt advanced solder technology, reduce base plate 7 and fin 8, the thermal resistance between base plate 7 and the heat pipe 9, it is more smooth and easy that heat passage is arrived.
4, the heat that LED is distributed is transmitted on the shell 1 of product with heat pipe 9, makes the whole system heat more even.
5, the gap is appropriate between the waist shape louvre of enclosing cover 10 and the fin, so that enclosing cover 10 do not stop the rising of thermal current substantially, plays better free convection effect, and then forms infundibulate cross-ventilation effect, and heat is by convection in the surrounding environment rapidly.
6, base plate 7 adopts the scrap (bridge) of anti-rainwater penetration mode to intercept rainwater, can make waterproof more reliable.
7, shell 1 adopts the die casting fin, can increase the whole system area of dissipation, and the heat that power supply is distributed in time is dispersed in the surrounding environment.
8, shell 1 front end adopts the design of waist type hollow out, makes whole system have good draining and dirt eliminating function.
9, employing heat conductive pad 6 can reduce the gap between aluminium base and the radiator, reduces thermal resistance, makes heat can import base plate 7 swimmingly.
10, the surface adopts baking vanish to handle, and makes the use of product meet the user demand of outdoor products fully, smooth surface, and outward appearance is beautiful.
11, Zhuan Ye dustproof and waterproof structural design reaches more than the IP65 IP grade of product, satisfies the outdoor products user demand fully.
12, use anti-aging silicone tube 12 as pipeline and waterproof, pipe joint 14 is fixed on pipeline on base plate 7 and the shell 1, can reach good waterproof effect.
The simple deformation or the combination of every the utility model embodiment technical scheme and technical characterictic all should be thought to fall into protection domain of the present utility model.
