Detailed description of the invention
In order to more fully understand technology contents of the present invention, below in conjunction with specific embodiment technical scheme of the present invention being introduced further and illustrating, but being not limited to this.
As shown in Figures 1 to 5, the LED that the present invention has a prismatic radiator have employed the embodiment of four bank or ridge radiator, it comprises lamp holder 10, and the power circuit (not shown) be located in lamp holder 10 and the radiator connected with lamp holder 10, radiator is provided with several LED lamp bead 20, radiator is the four bank or ridge 30 being provided with cavity 50, and LED lamp bead 20 is located at four surfaces of four bank or ridge 30; Four outer side surfaces of four bank or ridge 30 are also respectively connected with lampshade 40.Four surfaces of four bank or ridge 30 are provided with cavity 31, are provided with the pcb board 21 for fixed L ED lamp pearl 20 in cavity 31.The both sides of cavity 31 are provided with the inner fovea part 311 for embedding pcb board 21.The surperficial two edges of four of four bank or ridge 30 are provided with the draw-in groove 32 for embedding lampshade 40.Draw-in groove 32 is square draw-in groove; Lampshade 40 is provided with the square edge 41 for embedding in square draw-in groove.When installing, lampshade is the end from four bank or ridge 30, is pushed in by square edge 41 collimation dihedral draw-in groove.In order to reach the effect of waterproof, can also also be provided with a protective clear layer 42 in the periphery of four lampshades 40.Also comprise the shaped as frame lamp housing 60 for connecting four bank or ridge 30 and lamp holder 10, shaped as frame lamp housing 60 is provided with the inner chamber 61 for accommodating lamp holder 10, the bottom of inner chamber 61 and one end screw attachment of four bank or ridge 30, the edge of opening place of inner chamber 61 is provided with lug boss 62, the periphery of lamp holder 10 is provided with the groove 11 for embedding lug boss 62, do not need screw to fix, realize the Fast Installation of shaped as frame lamp housing and lamp holder with this.Wherein, one end of four lampshades of simultaneously also covering, the bottom of shaped as frame lamp housing.Lamp holder 10 is also provided with square lamp holder connection part 12, to be directly inserted on the lamp socket of standard.In order to attractive in appearance, and in order to cover the other end of four lampshades, be fixed with end cap 39 at the other end of four bank or ridge 30 by screw, end cap 39 is provided with several louvres 390, and the hot-air in cavity 50 is exchanged with extraneous cold air.Wherein, several radiating groove 51 and several thermal vias 52 are provided with in cavity 50.Thermal vias 52 is open type through holes, and at the two ends of four bank or ridge 30, thermal vias can also become the screw pre-manufactured hole of screw joints.
In order to reach better radiating effect, pcb board preferable alloy pcb board wherein.
In the above-described embodiments, because shaped as frame lamp housing one end by radiator covers completely, radiator only has one end can carry out heat exchange with the external world, and radiating effect is limited.As preferred embodiment, as shown in Figure 6 to 7, in this embodiment, play better thermolysis to make the cavity of radiator, add four surface grooves 63 at four outer surfaces of shaped as frame lamp housing 60, these four surface grooves 63 play the effect of cavity 50 with external communication.Because surface groove 63 communicates with the cavity 50 of radiator, in LED use procedure, heat is passed in cavity by radiator, now, air heats in cavity, the temperature difference with outside air is produced with this, now, the heat dissipation channel that louvre and radiator cavity and surface groove are formed, in the effect of the hot-air of cavity, produce convection current from the bottom up, form stack effect, form good radiating effect.
In other embodiment, also can adopt the radiator of triangular prism, five rib bodies or hexagonal prism; Also lamp holder connection part that is screw type or bayonet type can be adopted.
In other embodiment, each lampshade is a part for the tube shell that integral molded plastic is shaped.Namely also the lampshade of each outer side surface is a part for an overall tube shell, seems more attractive in appearance in appearance with what make LED, more as a whole.And can waterproof problem be solved, may be used for the use under particular surroundings, the freezer that such as humidity is larger.
In sum, the present invention utilizes the radiator of multiple edge body shape, at the outer surface mounted LED lamp bulb of radiator, to form the field of illumination of 360 degree, by the astigmatism effect of lampshade, realize the illumination of the uniform luminance of 360 degree with this, and the radiator of multiple edge body realizes the concentrated heat radiation of the LED lamp bead on multiple pcb board.Due to the reason of concentrated heat radiation, can form stronger hot-air convection motion, the LED for city's electric lighting is normally vertically installed, in the heat dissipation channel be made up of multiple louvre, cavity and surface groove, form cross-ventilation from the bottom up, there is fabulous radiating effect.Simultaneously due to concentrated radiator, decrease the volume of radiator, and improve the quantity of LED, add brightness and light area.
The above only further illustrates technology contents of the present invention with embodiment, so that reader is easier to understand, but does not represent embodiments of the present invention and is only limitted to this, and any technology done according to the present invention extends or recreation, all by protection of the present invention.Protection scope of the present invention is as the criterion with claims.
