Description

High-power LED lamp
Technical field
The utility model relates to the LED lighting field, mentions a kind of high-power LED lamp especially.
Background technology
LED has many advantages such as energy-saving and environmental protection as a kind of emerging green light source, is applied to various lighting fields by increasing.LED is a kind of solid state light emitter, through electric energy being converted into visible light output.Along with the continuous development of LED technology, the power of present led light source is very high, can send the light of high brightness, and this high-power LED has been applied in the lighting apparatus in various large-scale places.Though great power LED can send high-luminance light; But be subject to technology; It does not still reach 100% with the efficient that electric energy is converted into luminous energy, and some technology also just can reach about 80% than the transformation efficiency of the great power LED of advanced manufacturers produce at present, still have the electric energy about 20% to be converted to heat energy; If these heat energy can not conduct and distribute timely and effectively, can influence the service life of LED greatly from LED.Therefore, all can be equipped with various heat dissipation equipments in the existing high-power LED lamp, the heat among the LED is conducted and distributes.At present; The passive heat radiation structure that the heat dissipation equipment that adopts in the high-power LED lamp generally all is made up of a lot of fin; LED is installed to and is made the LED lamp plate on the aluminium base, and the LED lamp plate is installed to spreader surface again, and the heat radiation process is that heat is by conducting on the LED lamp plate on the substrate of radiator; Conduct on each fin, last fin distributes heat through thermal-radiating mode again.This radiator structure is not extra high LED light fixture for power; Radiating effect can meet the demands, but for the high-power LED lamp that needs super brightness, its radiating efficiency is wretched insufficiency; Because radiating efficiency is low excessively; Great amount of heat accumulates on the radiator, makes the heat on the LED be difficult to conduct on the radiator distribute again, and has seriously had influence on the service life of light fixture.
The utility model content
To the deficiency that above-mentioned prior art exists, the purpose of the utility model provides a kind of high-power LED lamp, and it has very excellent radiating effect, can satisfy the heat radiation requirement of the high-power LED lamp of super brightness.
To achieve these goals; The technical scheme that the utility model adopted is: high-power LED lamp; Comprise reflection shield and be installed on the led light source of the central hole of reflection shield, it is characterized in that said led light source comprises tubular cooler and is mounted on a plurality of LED lamp plates of radiator outer surface; Said radiator has outer tube and the interior pipe that is nested with together, between said outer tube and the interior pipe through a plurality of fin structure that links into an integrated entity.
Preferably, said outer tube is the regular prism shape, and each side all is pasted with a LED lamp plate.
Preferably, said interior pipe is cylindric or regular prism shape.
Preferably, also be provided with the heat radiation rib between the said fin, said heat radiation rib is extended and the unsettled setting in end by the madial wall of said outer tube.
Preferably, also be provided with the heat radiation rib between the said fin, said heat radiation rib is extended and the unsettled setting in end by the lateral wall of pipe in said.
The utility model compared with prior art has following advantage: through mount a plurality of LED lamp plates at the tubular cooler outer surface; The lighting requirement of super brightness can be provided; Certainly caloric value is also very big; Therefore radiator is designed to have outer tube and the interior pipe that is nested with together, between outer and pipe and the interior pipe through a plurality of fin structure that links into an integrated entity.After radiator is designed to this structure; Not only make the area of dissipation of radiator increase many times, in radiator, form many passages simultaneously, such as inner the passing through of interior pipe; And the passage that forms between fin, outer tube and the interior pipe; Because heat distribution is uneven, make that the air in the passage also can cold and hotly differ in these passages, air can form convection current fast on one's own initiative.So; Radiator not only can be through thermal-radiating mode distribute heat; Can also dispel the heat through air circulation better, radiating effect is become several fold to be increased, and the heat on the radiator just can be distributed fast; Can not form heat accumulation yet, can better more efficiently the heat on the LED be dissipated.Therefore the high-power LED lamp of the utility model has very excellent radiating effect, can satisfy the heat radiation requirement of the high-power LED lamp of super brightness.

The specific embodiment
The following stated is merely the preferred embodiment of the utility model, does not therefore limit the protection domain of the utility model, below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Embodiment; See that Fig. 1 is to shown in Figure 4: the utility model is a kind of high-power LED lamp; Comprise reflection shield 10 and be installed on the led light source 30 at centre bore 20 places of reflection shield 10, it is characterized in that said led light source 30 comprises tubular cooler 40 and is mounted on a plurality of LED lamp plates 50 of radiator 40 outer surfaces; Said radiator 40 has the outer tube that is nested with together 41 and interior pipe 42, between said outer tube 41 and the interior pipe 42 through a plurality of fin 43 structure that links into an integrated entity.The utility model compared with prior art has the following advantages: through mounting a plurality of LED lamp plates 50 at tubular cooler 40 outer surfaces; The lighting requirement of super brightness can be provided; Certainly caloric value is also very big; Therefore radiator 40 is designed to have the outer tube 41 and interior pipe 42 that is nested with together, between outer and pipe and the interior pipe 42 through a plurality of fin 43 structure that links into an integrated entity.After radiator 40 is designed to this structure; Not only make the area of dissipation of radiator 40 increase many times, in radiator 40, form many passages simultaneously, such as interior pipe 42 inner passing through; And the passage that forms between fin 43, outer tube 41 and the interior pipe 42; Because heat distribution is uneven, make that the air in the passage also can cold and hotly differ in these numerous passages, air can form convection current fast on one's own initiative.So; Radiator 40 not only can be through thermal-radiating mode distribute heat; Can also dispel the heat through air circulation better, radiating effect is become several fold to be increased, and the heat on the radiator 40 just can be distributed fast; Can not form heat accumulation yet, can better more efficiently the heat on the LED be dissipated.
In order to improve the area of dissipation of radiator 40, also make things convenient for the installation of LED lamp plate 50 simultaneously, said outer tube 41 is the regular prism shape, simultaneously, said interior pipe 42 is cylindric or the regular prism shape.In addition, in order further to advance to rise radiating effect, also be provided with heat radiation rib 44 between the said fin 43; Said heat radiation rib 44 is extended and the unsettled setting in end by the madial wall of said outer tube 41; Perhaps said heat radiation rib 44 is extended and the unsettled setting in end by the lateral wall of pipe 42 in said, makes between heat radiation rib 44 and the fin 43 and also can form some little passages, has both increased area of dissipation; Strengthen the cross-ventilation effect again, promote radiating effect better.
The high-power LED lamp of the utility model has very excellent radiating effect, can satisfy the heat radiation requirement of the high-power LED lamp of super brightness.
