Abstract

The invention proposes an LED lamp radiator. The LED lamp radiator comprises a baseplate, and multiple radiator chip sets distributed on the baseplate in a radial form; emitting initial ends of the radiator chip sets and the baseplate are surrounded to form a cavity; and convection channels are formed between the radiator chip sets, and are communicated with the cavity. The LED lamp radiator increases the cooling area of a radiator and the convection channels to improve the cooling effect; and the radiator can be matched with different light emitting modules to save the production cost.

Description

A kind of LED lamp radiator
Technical field
The present invention relates to a kind of heat abstractor, be specifically related to a kind of LED lamp radiator.
Background technology
LED down is a kind of lighting being flush-mounted in ceiling or wall interiors, can increase the soft atmosphere in space, builds warm sensation, alleviates space constriction.Because LED down is flush-mounted in ceiling or wall interiors, therefore ventilation condition is poor, and heat dissipation environment is bad, requires higher, otherwise can affect the normal work of LED lamp to the heat dispersion of Down lamp self, aggravation light decay, reduction of service life.Existing radiator mostly is hollow or solid cylinder is external is evenly equipped with radial radiating fin, and this radiator can not large area contact with illuminating module, affects heat conduction efficiency.In addition, due to the air not convection current between fin, heat can not shed in time, affects radiating effect.Therefore, the shortcoming existed in prior art, is necessary to make improvements prior art.
Summary of the invention
The object of the invention is to overcome shortcoming of the prior art with not enough, a kind of LED lamp radiator that can improve radiating effect is provided.
The present invention is realized by following technical scheme: a kind of LED lamp radiator, comprise base plate and be radially laid in the some groups of fins on base plate, the radiation top of described groups of fins and base plate enclose a cavity, have convection channel between described groups of fins, convection channel is communicated with described cavity.
Described groups of fins is axially symmetrical arranged.
Described groups of fins is made up of some fin radially laid.
Described groups of fins is made up of a slice fin.
Described groups of fins is made up of two panels fin, and the radiation top of described fin is connected by baffle plate.
Described groups of fins is made up of three fin, and the radiation top of described fin is connected by baffle plate, is provided with raised line in the middle part of the forward surface of the gelled baffle plate of described connection.
The sidepiece of described fin is provided with outward extending heat radiation lateral plate.
The bottom of described cavity is provided with a boss.
The sidepiece of described radiator is provided with the set screw that can be connected in panel rack.
Relative to prior art, have convection channel between groups of fins of the present invention, convection channel and cavity accelerate the convection current of radiator and outside air, improve radiating efficiency, the base plate of radiator can support the use multiple illuminating module, highly versatile, saves production cost.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
A kind of LED lamp radiator of the present invention as shown in Figures 1 to 4, comprise base plate 1 and be radially laid in the some groups of fins 2 on base plate 1, the radiation top of groups of fins 2 and base plate 1 enclose a cavity 4, have convection channel 5 between groups of fins 2, and convection channel 5 is communicated with cavity 4.Convection channel 5 and cavity 4 accelerate radiator and extraneous cross-ventilation, improve radiating efficiency.Base plate 1 can install the illuminating module of different model, reduces production cost.
Groups of fins 2 is axially symmetrical arranged, and is conducive to cross-ventilation.
Groups of fins 2 is made up of some fin 3 radially laid.As a kind of embodiment, groups of fins 2 adopts the 3rd groups of fins of the first groups of fins of monolithic, the second groups of fins of two panels and three respectively, and first, second and third groups of fins interval is arranged, and fin 3 number between adjacent two groups of fins 2 is different.Groups of fins 2 can be made up of a slice fin 3.Groups of fins 2 also can be made up of two panels fin 3, and the radiation top of fin 3 is connected by baffle plate 6.Groups of fins 2 can also be made up of three fin 3, and the radiation top of fin 3 is connected by baffle plate 6, is provided with raised line 7 in the middle part of the forward surface being connected with the baffle plate 6 of fin 3.
The sidepiece of fin 3 is provided with outward extending heat radiation lateral plate.The bottom of cavity 4 is provided with a boss 8.This baffle plate 6, heat radiation lateral plate and boss 8 can increase the area of dissipation of radiator, improve radiating efficiency.Certainly, fin 3 can offer louvre to improve radiating efficiency.
The sidepiece of radiator is provided with the set screw 9 that can be connected in panel rack.Certainly, the sidepiece of this radiator can offer screw hole 10, set screw 9 can be bolted in screw hole 10 thus fixing on a heat sink.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
