Abstract
The utility model relates to a transversely-inserted LED lamp with high heat dissipation efficiency. The transversely-inserted LED lamp comprises a lamp cap, a connecting piece, a lamp holder, a driver, a printed circuit board and a plurality of LED light sources, wherein the plurality of LED light sources are arranged on the printed circuit board and attached to one outer side wall of a rectangular tubular body of the lamp holder, the other three outer side walls of the rectangular tubular body of the lamp holder are respectively provided with a plurality of cooling fins, the cooling finds are arranged in the length direction of the tubular body, the thickness of each cooling fin ranges from 0.5mm to 0.6mm, the distance between every two adjacent cooling fins ranges from 0.8mm to 1mm, and the height of each cooling fin ranges from 3mm to 6mm. The three outer side walls of the aluminum alloy lamp base are respectively provided with the plurality of cooling fins, the thickness of each cooling fin is small, the distance between every two adjacent cooling fins is small, the height of each cooling fin is large, and therefore the heat dissipation efficiency is improved, the temperature of PN nodes of an LED is obviously lowered, and the service life is also remarkably prolonged.
Description
Technical field
The utility model relates to the horizontal slotting lamp of a kind of LED, and particularly the high radiator structure of the horizontal slotting lamp of a kind of LED, belong to the heat dissipation technology field.
Background technology
The LED lamp has the plurality of advantages of energy-saving and environmental protection, longevity, light, safety because of it, and is extensively used by modern society, and wherein whether is to be based upon to have on good cooling system the service life of light fixture.If only relying on and using the LED element of low thermal resistance is to build good cooling system for lamp device, and must effectively reduce the thermal resistance from the PN node to surrounding environment, could greatly reduce the PN node temperature of LED, Successful Practice extends the service life of LED light fixture and improves the target of actual luminous flux., in general conventional lamp, printed circuit board (PCB) is not the charge carrier that supplies of LED, and is the heat radiation carrier of LED, so the heat dissipation design of fin and printed circuit board (PCB) is very important yet.In addition, the processing of the quality of heat sink material, thickness and size and heat dissipation interface and connection etc. are also the key factors of radiator structure design.The horizontal slotting lamp of existing LED always can not effectively reduce the PN node temperature of LED in the radiator structure design, and radiating efficiency is also lower, and therefore, can not reach ideal effect its service life.
Summary of the invention
The purpose of this utility model is to provide a kind of horizontal slotting lamp of LED with high cooling efficiency, by the design of the heat radiating fin structure on the horizontal slotting lamp lamp socket of LED, improves radiating efficiency, reduces the PN node temperature of LED.
To achieve these goals, the utility model Bian gets following technical scheme and implements: a kind of horizontal slotting lamp of LED with high cooling efficiency, comprise lamp holder, connector, lamp socket, driver, printed substrate and a plurality of LED light source, be connected by connector between lamp holder and lamp socket; The aluminium alloy tubulose body that lamp socket is rectangle; Printed substrate is provided with a plurality of LED light sources and sticks on a lateral wall of lamp socket rectangular tubular body; Driver is inserted in lamp socket inside, it is characterized in that: other three lateral walls of described lamp socket rectangular tubular body are provided with some radiating fins; Described radiating fin is along the length direction setting of tubular body; The thickness of described radiating fin is arranged between 0.5～0.6mm; The described radiating fin often distance between adjacent two is arranged between 0.8～1mm: the height of described radiating fin is arranged between 3～6mm.
The utility model utilizes hot conduction, thermal convection current and the thermal radiation basic principle as heat radiation, basic ideas by increasing heat radiation area as the radiator structure design, thereby three lateral wall sections at the aluminium alloy lamp socket arrange some radiating fins, and thin thickness, the spacing of fin of radiating fin are intensive, fin height is large, therefore improved radiating efficiency, make the PN node temperature of LED obtain obvious decline, also obviously increase service life.
The utlity model has the advantages such as radiator structure is reasonable in design, heat transfer area is large, radiating rate is fast, the good long service life of the light efficiency of light fixture.
The accompanying drawing explanation
Accompanying drawing 1 is looked for master of the present utility model, the broken section structural representation;
The sectional structure schematic diagram that accompanying drawing 2 is A-A cross section in accompanying drawing 1.
In accompanying drawing 1,2: 1 lamp holder, 2 connectors, 3 lampshades, 4 printed substrates, 5 LED light sources, 6 lamp sockets, 601 radiating fins, 7 drivers.
The specific embodiment
As shown in accompanying drawing 1,2, between lamp holder and lamp socket 6, by connector 2, be connected; The aluminium alloy tubulose body that lamp socket 1 is rectangle; Printed substrate 4 is provided with a plurality of LED light sources 5 and sticks on a lateral wall of lamp socket 6 rectangular tubular bodies, and other three lateral walls of lamp socket 1 rectangular tubular body are provided with some radiating fins 601; Radiating fin 601 is along the length direction setting of tubular body; The thickness of radiating fin 601 is set to 0.5mm; Distance between every adjacent two of radiating fin 601 is set to 1mm: the height of radiating fin 601 is set to 3～6mm under profile rule, front topic attractive in appearance and does not wait meeting, driver 7 is inserted the inside at lamp socket 6, in the horizontal draw-in groove be inserted on lamp socket 6 of lampshade 3, and be sealed on the outside of printed substrate 4.
The utility model utilizes hot conduction, thermal convection current and the thermal radiation basic principle as heat radiation, basic ideas by increasing heat radiation area as the radiator structure design, thereby three lateral wall sections at aluminium alloy lamp socket 6 arrange some radiating fins 601, and thin thickness, the spacing of fin of radiating fin 601 are intensive, fin height is large, therefore increased area of dissipation, improved radiating efficiency, made the PN node temperature of LED obtain obvious decline, also obviously increase the service life of light fixture.
