Abstract
The utility model discloses an LED street lamp, which comprises a lamp screen with a light-transmitting lens and an LED lamp body mounted inside the lamp screen. The lamp screen is integrally cast by aluminum alloy and comprises a hollow turtle shell-shaped casing, wherein the outer surface of the casing adopts a smooth arc-shaped surface; and mounting surface belts matched with the two lateral sides of an LED substrate are horizontally extended in the opposite direction on the left side and the right side of the inner cavity of the casing, and heat radiation fins are vertically arranged outside the casing of the lamp screen above the mounting surface belts. The LED street lamp has greatly improved heat radiation effect and improved overall quality; the lamp screen and the heat radiator are cast in one step, the production process is simple, and the material is thinned so as to reduce production cost; and the whole back surface of the casing is a smooth arc-shaped surface, so as to reduce wind resistance and meet the relevant quality requirements.
Description
Technical field:
The utility model relates to a kind of street lamp, particularly a kind of LED street lamp.
Background technology:
Along with the popularization of low-carbon (LC), energy-conserving road lamp, the LED street lamp is widely used in the occasions such as road, street, public place of city prosperity gradually as representative in this respect.
Common LED street lamp, CN200810155549.2 is disclosed as patent application: lampshade, led light source, radiator, driving power, arm fastener and other accessory by the band light-distribution lens are formed, radiator, driving power box and arm fastener constitute lamp main body by aluminium alloy is integrated, led light source is fixed on radiator heat transfer substrate lower surface, forms the led light source array group and is connected to the driving power output positive and negative charge by printed circuit series connection back LED light source consisting string is in parallel again.Shown in this patent application Fig. 4 A, this radiator is generally the founding of aluminium alloy one and forms, and comprises solid base, and the base upper surface is cast with a lot of sheet fin, and the bottom surface of base is smooth, and the LED substrate is close to the lower plane of base, forms the light source heat radiation sheet.But the radiator of this structure, the heat radiation situation is undesirable when LED power is big, and when the 60W, the maximum temperature of LED substrate can reach about 90 ℃ as power; And owing to require bigger area of dissipation, the fin higher comparatively dense of design on base causes in when the fin side surface direction be the wind comes from, and the windage of lamp does not meet the relevant criterion requirement greatly; Because foot of radiator is solid, causes consume material and preponderance and do not meet the relevant criterion requirement in addition.
The utility model content:
Technical problem to be solved in the utility model is the defective that overcomes prior art, and a kind of LED street lamp that has the new structure radiator is provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of LED street lamp, comprise the lampshade of being with light-distribution lens and be installed on the interior LED lamp body of lampshade, described lampshade is formed by aluminium alloy or other metal integrally castings, comprise the turtle shell shape housing of hollow, this housing outer surface is smooth arcuation surface; In housing inner chamber left and right sides dual side-edge in opposite directions horizontal-extending cooperated with LED substrate dual side-edge mounting plane band is arranged, vertically be provided with fin in the lampshade shell outside of mounting plane band top; Be extended with the shirt rim downwards in the planar band periphery.
LED substrate like this is close to the mounting plane band and is incorporated on the lampshade, utilize the aluminium alloy of veneer to carry out the heat conduction on the one hand, upper surface, LED substrate middle part is exposed to the space that hollow housing forms on the other hand, the heat of substrate upwards is dispersed in the interior air of housing, and air forms the thermal convection current circulation and plays better heat radiating effect.
In addition, the shell wall of described housing can be done thinlyyer, and the control range of wall thickness is 3mm-20mm, so not only can save material, can also alleviate the oeverall quality of street lamp, the more important thing is wall thickness reduction, the outside radiating effect of air is better in the housing, has guaranteed that the LED substrate temperature meets the requirements.
Prior art is compared relatively, the utlity model has following advantage:
1, radiating effect obviously improves, and after tested, is example with the LED street lamp of 60W power, and the inside maximum temperature that records behind the work some hrs is obviously reduced to about present 67 ℃ by 88 ℃-90 ℃ of the LED street lamp of prior art.Can prevent so not only that temperature is too high and influence the LED life-span, and the temperature that is controlled at about 67 ℃ can make LED be in best luminance, improve the total quality of LED street lamp.
2, lampshade and the moulding of radiator one-step casting, explained hereafter are simple, the material attenuation has reduced production cost.
3, because back side of shell is smooth arcuation surface fully, thereby windage is reduced, satisfy the correlated quality requirement.
Description of drawings
Fig. 1 is the generalized section of the utility model embodiment.
Fig. 2 is the combination schematic diagram of the utility model embodiment.
The specific embodiment:
As shown in Figure 1 and Figure 2, a kind of LED street lamp of the utility model embodiment comprises the lampshade 2 of a band light-distribution lens 1 and is installed on LED lamp body 3 in the lampshade 2; Lampshade 2 is formed by the aluminium alloy integrally casting, lampshade 2 comprises the turtle shell shape housing of a hollow, the wall thickness of housing is 5mm, in housing inner chamber left and right sides dual side-edge in opposite directions horizontal-extending cooperated with LED substrate 5 dual side-edge mounting plane bands 6 are arranged, LED substrate 5 close installation vertically are provided with fin 4 in the lampshade shell outside of mounting plane band 6 tops on planar band 6; Be extended with the shirt rim downwards in the planar band periphery.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction; Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
