The invention aims to solve the technical problem about provision of the novel LED lamp with the radiating structure capable of maintaining the same light emergence surface area and increasing the radiating surface area.
Description
Technical field
The invention belongs to LED technology field, be specifically related to a kind of LED.
Background technology
The heat radiation operation principle of LED is dispelled the heat in the surface that the heat of LED light-emitting component conducts to radiator by the metal heat conducting-body in radiator.Because the dimensional structure of the LED of every type is determined, therefore when the design of lamp, surperficial demand fulfillment bright dipping and the cooling requirements of lamp must be considered, increase if light output surface is long-pending, then light output is also corresponding increases, but cooling surface area then can diminish, and radiating effect is deteriorated; Reduce if light output surface is long-pending, then light output is also corresponding diminishes, but cooling surface area then can become large, and radiating effect improves.
LED in prior art, particularly omnirange LED, all include lamp holder, radiator, driving power, LED light source and light transmitting shell usually.The structure of radiator is as Fig. 1, and metal heat conducting-body 30 is coated on the inside of insulation shell 10, arranges a cylindrical section in the upper end of insulation shell 10, and lamp holder 20 and cylinder are riveted adiabatic fixing, and the surface area of such lamp holder cannot be used for dispelling the heat.
In order to obtain the light output of higher LED, light output surface can only be strengthened and amass, will cooling surface area be reduced like this, heat conduction and heat radiation degradation, or lamp pearl quantity in LED light-emitting component must be increased in order to reach heat dispersion, the cost of lamp can be caused to increase.
Summary of the invention
Technical problem to be solved by this invention is to provide one that same light output surface can be kept to amass, and can increase again the LED of the radiating structure of cooling surface area.
The present invention adopts following technical proposals to realize:
A kind of LED of radiating structure, comprise lamp holder, radiator, LED light-emitting component, driving power and light transmitting shell, driving power arranges the inside of radiator, light transmitting shell connects radiator, be electrically connected between described lamp holder, driving power, LED light-emitting component, described radiator comprises metal heat conducting-body and insulation shell, the upper end of metal heat conducting-body arranges a cylindrical section, described insulation shell is coated on the outer surface of the metal heat conducting-body except cylinder, the cylinder of described metal heat conducting-body upper end and lamp holder are riveted fixing, and lower end is connected with LED light-emitting component.
The inner surface of described metal heat conducting-body is also coated with insulation shell.
Described lamp holder adopts E27, E26, E17, E14, E12, B22, B15 structure.
Described metal heat conducting-body is made for adopting aluminum metal.
The advantage of the LED of radiating structure of the present invention is:
1, because the cylinder of the metal heat conducting-body upper end in radiator of the present invention and lamp holder are riveted fixing, the heat of LED light-emitting component can be directly transferred to base surface by metal heat conducting-body, which increases the cooling surface area of LED, higher light output can be obtained under identical light-emitting component, or under identical light output condition, the lamp pearl quantity in light-emitting component can be reduced, save cost.
2, due to the actual lighting environment of LED, as Down lamp, LED is connected with the lamp socket in Down lamp by lamp holder, and lamp socket is connected with down lamp bracket.Lamp cylinder due to Down lamp is a semi-enclosed space, during lighting, the heat of lamp can make the air themperature in lamp cylinder raise, radiator insulation shell top cylinder and the lamp holder of existing LED are adiabatic connections, therefore the heat of spreader surface can only exchange with the air of higher temperature in lamp cylinder, and therefore heat-sinking capability is poorer.The heat of LED light-emitting component of the present invention can dispel the heat from base surface, lamp socket, down lamp bracket, has good heat dispersion.
3, well-known, base surface may be used for heat radiation, but in existing LED lamp structure, radiator insulation shell top cylinder and lamp holder are all adiabatic connections, all lamp holder are not used for heat radiation.From Electrical Safety angle, general engineering technology personnel all think, the metal heat conducting-body of the radiator of LED should be not charged, and because this project relates to the safety test of product, therefore common engineering teacher can not be designed for heat radiation base surface.As specified in UL safety standard: the isolation that must have 1.2 millimeters of distances between current-carrying part and on-current-carrying part.Therefore commonly in prior art to be interpreted as: metal heat conducting-body is interpreted as the on-current-carrying part in this standard, and lamp holder is current-carrying part, and so must have the insulation of 1.2 millimeters between metal heat conducting-body and lamp holder, obvious this understanding is wrong.Therefore the on-current-carrying part in understanding standard of the present invention refers to human body, the metal heat conducting-body that current-carrying part is lamp holder and rivets with lamp holder, between current-carrying part and on-current-carrying part, the insulation of 1.2 millimeters of required distances is insulation shells of 1.2 mm of thickness of the outer surface of metal heat conducting-body radiator is coated on except cylinder, so the direct riveted joint of metal heat conducting-body and lamp holder fixedly meets UL safety and requires in the present invention.
