Abstract
The utility model relates to a novel lamp radiator for an LED streetlamp, which includes a bottom surface connected with a PCB for mounting an LED lamp, and radiating fins arranged on the bottom surface of the radiator, wherein the front end of the radiator is connected with a decorative cover, the radiating fin in the middle of the radiator is the highest, and the radiating fins are symmetrically arranged on two sides of the highest radiating fin. In the technical scheme provided by the utility model, the distances between the adjacent radiating fins in the radiator are widened gradually from the root to the tip, thereby facilitating air flow and improving radiating effect; and meanwhile, the radiator and a lamppost fixing piece are contacted in large area, thereby greatly enlarging the radiating area of the radiator, increasing the radiating speed, further ensuring the radiating effect for a long time, and prolonging the service life of the lamp.
Description
Technical field
The utility model relates to the heat abstractor of lighting, specifically is a kind of Novel LED street lamp lamp radiator.
Background technology
Compare with traditional street lamp, the LED street lamp that utilizes the LED lamp to do light source not only has the characteristics that colourity is good, non-maintaining, the life-span is long, and the more important thing is, and is more energy-conservation than conventional road lamp, is a kind of communal facility of energy-conserving and environment-protective.
As the LED street lamp, heat radiation is technological difficulties, and the LED street lamp on the market has all added radiator now, and these radiators are close to the pcb board that the LED lamp is installed, and a large amount of heats that the LED lamp is distributed conduct in the ambient airs, take away by cross-ventilation.Radiator of the prior art is of a great variety, all be utilize metal particularly aluminium alloy extrusions make, in the one side of section bar the fin of some convex is set, to increase the area that contacts with air, but, space between these fin is very dark, adds that the distance between each fin is little, therefore, after heat is delivered in the air in the gap, if do not add the external force that ventilates, such as blowing air is wherein blown away, its heat radiation fruit will be had a greatly reduced quality.In addition, the lamp stand fixture itself fixing as street lamp and lamp stand all is that aluminum alloy materials is made, also be a kind of good conductor of heat, the contact area between radiator of the prior art and the lamp stand fixture is little, can not utilize the lamp stand fixture that heat is led away fully.
The utility model content
At the weak point that exists in the above-mentioned technology, the utility model provides a kind of good heat dissipation effect, Novel LED street lamp lamp radiator more attractive in appearance.
For achieving the above object, the utility model provides a kind of Novel LED street lamp lamp radiator, comprise trim, the bottom surface and the fin that are connected with the pcb board that the LED lamp is installed, described fin is arranged on the bottom surface of radiator, the front end of radiator is connected with trim, fin in the middle of the radiator is the highest, and described fin is symmetricly set in the both sides of high fin.
Also be provided with fin on the described trim.
Described each fin increases arrangement from outside to inside successively, and the cross section of each fin is trapezoidal.
Be provided with groove between the described fin, the width of described groove is identical.
Compared with prior art, the utlity model has following advantage:
In the technical solution of the utility model, the broadening gradually from the root to the tip of the distance between each fin in the radiator helps air and flows, improve radiating effect, contact with lamp stand fixture large tracts of land simultaneously, increased the area of dissipation of radiator greatly, accelerated the speed of heat radiation.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
The main element symbol description is as follows:
1, fin 2, groove 3, trim 4, bottom surface 5, radiator
The specific embodiment
In order more clearly to explain the utility model, the utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model provides a kind of Novel LED street lamp lamp radiator, comprise trim 3, the bottom surface 4 and the fin 1 that are connected with the pcb board that the LED lamp is installed, fin 1 is arranged on the bottom surface 4 of radiator, the front end of radiator is connected with trim 3, the height maximum of the fin 1 in the middle of the radiator, fin 1 is symmetricly set in the both sides of high fin, also be provided with fin 1 on the trim 3, fin 1 increases arrangement from outside to inside successively, the cross section of each fin 1 is trapezoidal, is provided with groove 2 between the fin, and the width of groove 2 is identical.
When mounted, can contact with the lamp stand fixture, and the lamp stand fixture also is to be made by aluminium alloy extrusions that the surface is all passed through special anode and handled, and has good heat-conducting in large area, a large amount of heats that the LED lamp produces can be distributed rapidly.The height of each fin has nothing in common with each other, and increases arrangement from outside to inside successively, and the cross section of each fin is trapezoidal, and the root of each fin is greater than the tip.Thus, each fin ambient air can both exchange with outside air and form convection current, simultaneously, fin is made the shape that root is big, the tip is little, makes little, top big apart from root between each fin, helps circulation of air, helps the heat convection current.
More than disclosed only be several specific embodiment of the present utility model, but the utility model is not limited thereto, any those skilled in the art can think variation all should fall into protection domain of the present utility model.
Claims (4)
1. Novel LED street lamp lamp radiator, comprise trim, the bottom surface and the fin that are connected with the pcb board that the LED lamp is installed, it is characterized in that, described fin is arranged on the bottom surface of radiator, the front end of radiator is connected with trim, fin in the middle of the radiator is the highest, and described fin is symmetricly set in the both sides of high fin.
2. a kind of Novel LED street lamp lamp radiator according to claim 1 is characterized in that, also is provided with fin on the described trim.
