Abstract

The utility model discloses a light-emitting diode (LED) lamp using a combined fin radiator, which comprises a lamp body. The lamp body comprises the combined fin radiator, an LED light source assembly installed on the combined fin radiator and an LED driving assembly. The LED light source assembly is installed on the combined fin radiator which is formed by assembling a radiator baseboard and a plurality of fins in punching mode. The combined fin radiator is not integrally formed so that the fins can be processed into thin sheet type with relatively small thickness and finally punched into the fin radiator in clamping mode. Due to the fact that the thickness of the fins is small, more fin assemblies can be arranged. The whole weight is small, installation is convenient, radiating area can be enlarged, and radiating efficiency is improved. The fins can be distributed according to convection of the air, radiating effect can be improved, and the LED lamp can be applied to LED light sources with large power.

Description

A kind of LED light fixture that adopts the combined type fin slices radiator

Technical field

The utility model relates to a kind of LED light fixture, particularly a kind of LED light fixture that adopts the combined type fin slices radiator.

Background technology

LED since advantages such as its volume is little, power consumption is low, long service life, high brightness, low in calories, environmental protection popularized gradually in daily life.But along with the increase of the power of LED, the heat that LED distributed also increases, and the LED long-term work causes light decay too fast under hot environment easily, reduces its heating efficiency and life-span.All be to dispel the heat through one-body molded aluminium matter fin substrate or aluminium matter fin shell traditionally, such advantage is that lamp body structure is firm, one-body molded easy for installation, but weight is excessive; And integrated radiator is owing to the restriction of process technology, and the thickness of fin can be bigger, and less fin can only be set; Area of dissipation is little, is unfavorable for distributing of heat, can only be applied to the led light source below 30 watts; For greater than 30 watts led light source, radiating effect is bad.

Summary of the invention

In order to overcome the deficiency of prior art, the utility model provides a kind of LED light fixture that adopts the combined type fin slices radiator, and this LED light fixture heat radiation is good, applicable to high-power LED light source.

The utility model solves the technical scheme that its technical problem adopted:

A kind of LED light fixture that adopts combined type combined type fin slices radiator; Comprise lamp body; It is characterized in that said lamp body comprises the combined type fin slices radiator, is installed in led light source assembly and LED driven unit on the combined type fin slices radiator, said combined type fin slices radiator is assembled by radiator base plate and multi-disc fin.

Described combined type fin slices radiator is fastened by radiator base plate and the punching press of multi-disc fin and forms.

Said led light source assembly comprises the led light source module that is installed on the combined type fin slices radiator, is fixed on aluminium lid, reflector, lens, pressure ring and annulus on the combined type fin slices radiator; Aluminium lid is provided with the jump ring assembly; Pressure ring is withheld on aluminium lid through the jump ring assembly, and is pressed on reflector, lens and annulus in the formed space of aluminium lid successively.

Said LED driven unit comprises that LED drives and support, and LED drives and is fixed on the combined type fin slices radiator through support.

The beneficial effect of the utility model is: the led light source assembly is installed on the combined type fin slices radiator, and the combined type fin slices radiator is fastened by radiator base plate and the punching press of multi-disc fin and forms, owing to be not one-body molded; Fin can be processed into the less sheet type of thickness as required, is buckled into fin slices radiator through punching press at last, because fin thickness is little; More fin combination can be set, and overall weight is light, and is easy for installation; And the increasing area of dissipation, improve radiating efficiency, can also arrange fin according to the convection current of air; Improve radiating effect, can be applied to than the high-power LED light source.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further specified:

Fig. 1 is the utility model overall structure sketch map;

Fig. 2 is the structural representation after the utility model assembling.

The specific embodiment

With reference to Fig. 1, Fig. 2, Fig. 1, Fig. 2 are the structural representation of the utility model one specific embodiment, and be as shown in the figure; A kind of LED light fixture that adopts combined type combined type fin slices radiator comprises lamp body 1, and lamp body 1 comprises combined type fin slices radiator 2, is installed in led light source assembly 3 and LED driven unit 4 on the combined type fin slices radiator 2; Combined type fin slices radiator 2 is fastened with the 21 assembling punching presses of multi-disc fin by radiator base plate 22 and forms, owing to be not one-body molded, fin 21 can be processed into the less aluminium matter sheet type of thickness as required; Be buckled into combined type fin slices radiator 2 through punching press at last,, more fin combination can be set because fin thickness is little; Overall weight is light, and is easy for installation, and strengthens area of dissipation; Improve radiating efficiency; Can also arrange fin 21 according to the convection current of air, improve radiating effect, can be applied to than the high-power LED light source.Fin 21 can be processed into the sheet type of various external forms as required, to be combined into the combined type fin slices radiator 2 of different external forms, to satisfy different installation needs; And combined type fin slices radiator 2 can also for example be changed nickel and handle through certain chemical treatment, improves the resistance to corrosion of aluminium matter fin 21, prolongs its service life.

As shown in the figure; Led light source assembly 3 comprises the led light source module 31 that is installed on the combined type fin slices radiator 2, is fixed on aluminium lid 32, reflector 33, lens 34, pressure ring 35 and annulus 36 on the combined type fin slices radiator 2; Aluminium lid 32 is provided with jump ring assembly 321; Pressure ring 35 is withheld on aluminium lid 32 through jump ring assembly 321, and successively reflector 33, lens 3) and annulus 36 be pressed in the aluminium lid 32 formed spaces, make the light that penetrates on the led light source module 31 penetrate light fixtures through scioptics behind reflector 33 reflecting condensations 34; Pressure ring 35 is withheld at aluminium lid 32 through jump ring assembly 321, and is quick and easy for installation.
