Technical field

The utility model 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, use, especially with the white light LEDs road lighting of light source, the many countries in 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 can not cover the dark space between two lamps to road surface, lamp lower end, often causes bright on the road, dark alternate " zebra stripes " phenomenon.2, radiating effect is bad, existing high-power LED lamp, especially street lamp, and adopting at present the most extensive is that appearance by light fixture self is provided with a large amount of fin, sheds by outer surface and the heat of natural convection air with the LED generation.This radiating mode simplicity of design, but radiating efficiency is not high, simultaneously because the existence of a large amount of fin, 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.

The utility model content

The utility model aims to provide a kind of distribution curve flux that can solve present LED light fixture well and is difficult to satisfy the requirement of road lighting and the easy laying dust of lamp outer casing, the LED radiating effect is bad, useful life is short problem.

The purpose of this utility model is to realize by following technical measures:

It is wing that radiator bottom is bat, and the LED heat sink strip is triangular in shape or convex or triangle convex, and LED is heat sink directly to stick on the bottom of LED heat sink strip transverse slat, and lens are placed in above the LED, and the lens pressing plate is fixed on the LED heat sink strip by screw; Its bottom is the groove that the wing radiator of bat is provided with the corresponding LED heat radiation of or one or more strip; One or more than one LED heat sink strip risers pass the strip groove and the bat wing radiator of bat wing radiator and fix, and the top of heat sink strip riser exposes radiator, and the bat wing radiator is fixed on the light fixture upper casing by screw; Device has the radiator fan more than or in the light fixture, and the LED heat sink strip that exposes on the radiator is directly dispelled the heat.

The bottom is the wing radiator of bat and is provided with radiating ribs, LED is welded on and constitutes the LED lamp plate on aluminium base or the pcb board, one or more than one LED lamp plates are close to and are fixed on radiator and are the wing bottom of bat, lens are placed in above the LED, the lens pressing plate is fixed on radiator by screw and is the wing bottom of bat, and the bat wing radiator is fixed on the light fixture upper casing by screw; Device has the radiator fan more than or in the light fixture, and the LED radiating ribs that exposes on the radiator is directly dispelled the heat.

Its bottom of radiator or be the plane, or arc is polyhedral, or semicircle is polyhedral, or hemispherical is polyhedral.

Radiator fixed head or light fixture are provided with louvre.

Said structure of the present utility model can adapt to 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.

Advantage of the present utility model is: 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 the LED street lamp, it is wing that the bottom design of radiator becomes to be bat, by the cooperation of LED, the light shape of LED street lamp distributed reach the requirement of the wing luminous intensity distribution of bat, avoids the dark space that occurs between two lamps, reaches the optimum efficiency of not only energy-conservation but also investment-saving.2, adopt the LED heat sink strip to be fastened on the mode of radiator bottom, can be fit 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 the radiator, increase the light fixture inner chamber and get speed air flow, so that take away the heat on the radiating ribs on heat sink strip or the radiator fast, improve radiating effect, thereby guaranteed the Acceptable life of LED.
