Technical field
The present invention relates to a kind of LED light fixture, especially a kind of built-in radiation type LED lamp fixture.
Background technology
LED light source is with advantages such as its energy-saving and environmental protection, life-span length, on high-power LED lamp, apply, especially the road lighting take white light LEDs as light source, many countries of the world try out, but there are many problems: 1, because the directionality of LED is very strong, the most of direct projection of light, to road surface, lamp lower end, can not cover the dark space between two lamps, often causes bright on road, dark alternate " zebra stripes " phenomenon.2, radiating effect is bad, existing high-power LED lamp, especially street lamp, and adopting is at present the most extensively, by the appearance of light fixture self, a large amount of fin is set, heat LED being produced by outer surface and natural convection air sheds.This radiating mode simplicity of design, but radiating efficiency is not high, simultaneously due to the existence of fin in a large number, not only cause light fixture overweight, and make the easy laying dust of lamp outer casing, further reduced the maintenance factor of radiating effect and light fixture, cause its light decay very fast, useful life is shorter.Therefore, above-mentioned problem also becomes the bottleneck that apply in obstruction LED light fixture, especially road lighting field.
Summary of the invention
The present invention aims to provide a kind of distribution curve flux that can solve well current LED light fixture and is difficult to meet the requirement of road lighting and the easy laying dust of lamp outer casing, LED radiating effect is bad, useful life is shorter problem.
The object of the invention is to realize by following technical measures:
Radiator bottom is bat-wing, and LED heat sink strip is triangular in shape or convex or triangle convex, and LED is heat sink directly sticks on the bottom of LED heat sink strip transverse slat, and lens are placed in above LED, and lens pressing plate is screwed on LED heat sink strip; Its bottom is the groove that is provided with or one or more corresponding LED heat radiation strip on the radiator of bat-wing; One or more than one LED heat sink strip risers are fixed through strip groove and the bat-wing radiator of bat-wing radiator, and the top of heat sink strip riser exposes radiator, and bat-wing radiator is screwed in light fixture upper casing; The in-built radiator fan being equipped with more than or of light fixture, directly dispels the heat to the LED heat sink strip exposing on radiator.
Bottom is on the radiator of bat-wing and is provided with radiating ribs, LED is welded on and on aluminium base or pcb board, forms LED lamp plate, one or more than one LED lamp plates are close to and are fixed on the bottom that radiator is bat-wing, lens are placed in above LED, lens pressing plate is screwed in the bottom that radiator is bat-wing, and bat-wing radiator is screwed in light fixture upper casing; The in-built radiator fan being equipped with more than or of light fixture, directly dispels the heat to the LED radiating ribs exposing on radiator.
Its bottom of radiator or be plane, or arc is polyhedral, or semicircle is polyhedral, or hemispherical is polyhedral.
On radiator fixed head or light fixture, be provided with louvre.
Said structure of the present invention can adapt to the LED light fixtures such as various LED street lamps, LED Tunnel Lamp, LED Projecting Lamp, LED shot-light, LED court lamp, LED tennis court lamp, the high canopy lamp of LED.
The invention has the advantages that: 1, the bottom shape of radiator is set, to reach the effect of lamp distribution curve according to the different distribution curve flux of various light fixtures.As on LED street lamp, the bottom design of radiator becomes to be bat-wing, by the cooperation of LED, the light shape of LED street lamp is distributed and reach the requirement of bat-wing luminous intensity distribution, avoids the dark space that occurs between two lamps, reaches the not only optimum efficiency of energy-conservation but also investment-saving.2, adopt LED heat sink strip to be fastened on the mode of radiator bottom, can be applicable to the assembling of various lamp distribution curves, and be convenient to maintain and replace.3, lamp outer casing does not have fin, can not produce laying dust, and lamp housing is by rainwater, dust to be washed, and is convenient to light fixture and safeguards.4, adopt built-in active radiator structure and increase louvre, radiator fan directly dispels the heat to the radiating ribs on LED heat sink strip or radiator, increase light fixture inner chamber and obtain speed air flow, to take away fast the heat in the radiating ribs on heat sink strip or radiator, improve radiating effect, thereby guaranteed the Acceptable life of LED.
