Abstract

The utility model discloses a LED light distribution structure of combined application. The LED light distribution structure is characterized in that the structure comprises six planes, each plane is provided with a plurality of LED light sources which form a LED module, each LED is provided with lenses or reflectors, the lenses or the reflectors on the same plane have the same light extraction angle and the inclination angle of each plane makes the central vertical line of the plane direct the area to be illuminated by the LED light source. The utility model comprises fix planes, effectively increases the density of the LED light source and the heat dissipation area of the LED light source and can improve the illumination evenness degree effectively. The lenses and the reflectors assembled on the LED mould of each plane have the same light extraction angle, therefore when few LED light sources cease to work, the whole system can still meet the basic illumination requirement.

Description

A kind of LED light distribution structure of applied in any combination

Technical field

The utility model relates to a kind of LED lighting engineering, relates to a kind of LED light distribution structure of applied in any combination specifically.

Background technology

LED is energy saving and environment friendly new type light source, along with improving constantly of LED luminous efficiency, and will be more and more widely in the application of functional lighting field.Led light source to the similarity light source carries out secondary light-distribution, is one of high-power and high-luminance LED light source difficult point in functional illumination is used.At present, developed some and great power LED has been carried out the lens and the reflector of secondary light-distribution, but in actual applications, still there are many restrictions in these lens and reflector when application LED does large area lighting, mainly show as: in the combined type of high-power LED light source is used, planar alignment can produce restriction to LED, and can cause heat radiation abundant inadequately; Under the situation that curved surface is arranged, when a certain LEDs or a few LEDs lost efficacy, can cause whole system can't satisfy problems such as lighting criteria demand and uniformity of illuminance are not enough and take place.These problems have limited the application of great power LED in functional illumination especially large area lighting greatly.

Summary of the invention

The purpose of this utility model is to overcome defective of the prior art, even the LED light distribution structure of a kind of applied in any combination that a kind of illumination is even, the abundant minority led light source of heat radiation lost efficacy also can satisfy lighting requirement is provided.

The purpose of this utility model is achieved in that a kind of LED light distribution structure of applied in any combination, it is characterized in that: this structure comprises six planes, the some LEDs light sources of assembling are formed the LED module on each plane, be equipped with lens or reflector on every LEDs, lens on the isoplanar or reflector have identical rising angle, and the angle of inclination on each plane is that the planar central vertical line points to the zone that led light source need throw light on.

The LED light distribution structure of applied in any combination of the present utility model compared with prior art has following advantage: 1,6 planar combination can effectively increase led light source density, but also can increase the area of dissipation of led light source; 2, can effectively improve uniformity of illuminance, lens or reflector on the LED module that each plane is assemblied in have identical rising angle, and when wherein minority led light source lost efficacy, whole system still can satisfy basic illumination needs; 3, the utility model can be applied to large area lighting occasions such as floodlighting, road lighting and industrial lighting.

Description of drawings

Fig. 1 is the perspective view of the LED light distribution structure of the utility model applied in any combination.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described further.

Embodiment 1: a kind of LED light distribution structure of applied in any combination, this structure comprises six planes 1,2,3,4,5,6, its midplane 1 and plane 2 each self-assembly eight LEDs light source 8, plane 3 and plane 4 each self-assembly 16 LEDs light source 8, plane 5 and plane 6 each self-assembly four LEDs light source 8, the some LEDs light sources 8 of assembling are formed a LED module on each plane, be equipped with reflector 7 on every LEDs, reflector 7 on the isoplanar has identical rising angle, and the angle of inclination on each plane is that the planar central vertical line points to the zone that led light source need throw light on.
