Abstract
The utility model provides a radiator for an LED lamp. The radiator for the LED lamp comprises a round base plate, wherein the lower surface of the round base plate is provided with limiting clamping points and screw holes, the limiting clamping points and the screw holes are used for installation of LED lamp beads, an arc-shaped section which is arranged around the round base plate is arranged on the edge of the round base plate, and a plurality of cooling fins are arranged on the outer surface of the arc-shaped section. According to the technical scheme, the arc-shaped section is arranged around the base plate, the cooling fins are arranged on the outer surface of the arc-shaped section, and thus heat emitted by LEDs is dissipated to the space around the base plate through the cooling fins; compared with a traditional radiator which adopts a central cooling method, the radiator for the LED lamp has the advantages that heat is prevented from accumulated on the back sides of the positions where the LED lamp beads are installed, and the radiator is extremely exquisite and attractive in appearance.
Description
Technical field
The utility model relates to lighting apparatus field, refers to especially a kind of LED lamp radiator.
Background technology
In recent years, the development of semiconductor light sources light emitting diode (LED) is but very rapid, and the luminous efficiency of part LED has substantially exceeded incandescent lamp, even exceeded the luminous efficiency of fluorescent lamp.Compared with traditional Projecting Lamp electric light source, the basic nonhazardous of LED light source, no electromagnetic pollution and have that volume is little, energy consumption is low, light efficiency is high, caloric value is relatively low and many-sided advantage such as long service life, can substitute conventional light source and make various light fixtures and roads light.
But the lamp that this LED makes but has the problem that caloric value is large, thus the problem such as the light generation flavescence that easily causes LED to send is dimmed.And high temperature also easily causes the generation of dangerous situation.Based on this, someone has proposed to install additional the high temperature problem of radiator when solving LED work on LED lamp.The radiator that people use is now mostly the mode that multi-disc radiating fin is vertically set on substrate, and such radiating effect is not fully up to expectations, and not attractive in appearance.
Therefore, how providing a kind of radiator of effective solution heat dissipation problem, is the problem the most in the urgent need to address that LED light source faces in LED lamp applications.
Utility model content
The utility model proposes a kind of LED lamp radiator, solved the problem that cannot solve the heat radiation of LED lamp in prior art.
The technical solution of the utility model is achieved in that
A kind of LED lamp radiator, comprise: circular substrate, described circular substrate lower surface is provided with spacing stuck point and the screw for mounted LED lamp bulb, and described circular substrate edge is provided with the arc section arranging around described circular substrate, and described arc section outer surface is provided with several radiating fins.
Further, described radiating fin is along the described circular substrate central point layout that is centrosymmetric.
Further, described radiating fin and described arc section are vertical setting.
Further, described radiating fin is shaped as fan-shaped take substrate edges place as the center of circle, and each edge of described radiating fin is all arc transition.
Further, described several radiating fins are divided into some groups, and the outer of every group of each described radiating fin connects by arc heat sink.
Further, described arc section inner surface is provided with the reinforcement for preventing described arc section distortion.
The beneficial effects of the utility model are: pass through such scheme, substrate is arranged to arc section around, and at arc section outer surface, radiating fin is set, the heat that LED is sent around distributes to substrate by radiating fin, than the mode of traditional heat-dissipating device center heat radiation, the utility model LED lamp radiator can not gather heat at the back side of LED lamp pearl installation place, has improved radiating effect, and very exquisite attractive in appearance.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the first perspective view of an embodiment of a kind of LED lamp of the utility model radiator;
Fig. 2 is the second perspective view of the radiator of LED lamp shown in Fig. 1.
In figure, 1 is circular substrate, and 2 is arc section, and 3 is radiating fin, and 4 is arc heat sink, and 5 is spacing stuck point, and 6 is screw, and 7 is reinforcement.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Referring to an embodiment of a kind of LED lamp of the utility model shown in Fig. 1 and Fig. 2 radiator, comprise: circular substrate 1, described circular substrate 1 lower surface is provided with spacing stuck point 5 and the screw 6 for mounted LED lamp bulb, LED lamp pearl can be directly loaded on the utility model LED lamp radiator, the heat that LED lamp pearl is distributed is directly gone out by heat sink radiates, thereby thereby has avoided the not good problem of radiating effect causing because being also provided with other parts between LED lamp pearl and radiator in traditional LED lamp.
Described circular substrate 1 edge is provided with the arc section 2 arranging around described circular substrate 1, and described arc section 2 outer surfaces are provided with several radiating fins 3.Described radiating fin 3 is along the described circular substrate 1 central point layout that is centrosymmetric.Described radiating fin 3 is vertical setting with described arc section 2.Described radiating fin 3 is shaped as fan-shaped take substrate edges place as the center of circle, and each edge of described radiating fin 3 is all arc transition.A kind of LED lamp of the utility model radiator is by the above-mentioned mode that radiating fin 3 is arranged to circular substrate 1 outer arc section 2, the heat that LED is sent around distributes to substrate by radiating fin 3, than the mode of traditional heat-dissipating device center heat radiation, the utility model LED lamp radiator can not gather heat at the back side of LED lamp pearl installation place, improved radiating effect, and very exquisite attractive in appearance.
In the present embodiment, radiating fin 3 has 20, is equally divided into 10 groups, and the outer of every group of radiating fin 3 connects by arc heat sink 4, forms the approximate lotus flower effect of center radiation shape, has greatly improved aesthetics.Also can be set to one, three or more radiating fins 3 is one group, within such structural change still falls into protection domain of the present utility model.
Preferably, described arc section 2 inner surfaces are provided with the reinforcement 7 for preventing that described arc section 2 is out of shape.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
