Description

High efficiency LED modulated structure

Technical field

The utility model relates generally to a kind of high efficiency LED modulated structure.

Background technology

Related known structure in the prior art, as with Chinese patent application number being that 200710043662.7 high-power LED street lamp is an example, the major technique of this high-power LED street lamp is characterized as: be provided with the matrix that most led light source module installings are provided, this matrix protrudes out setting towards high-power high-efficiency LED lamp light direction on the whole, and be provided with most loading ends towards high-power high-efficiency LED lamp light direction for the carrying of led light source module at it, the end face of described each loading end is with matrix end face center symmetry, the angle that first loading end that next-door neighbour's matrix end face center is provided with in the described loading end and matrix end face median plane form is 76 °～86 °, the angle that second loading end of next-door neighbour's first loading end setting and matrix end face median plane form in the described loading end is 49 °～59 °, and the angle that the 3rd loading end of next-door neighbour's second loading end setting and matrix end face median plane form in the described loading end is 37 °～47 °.

The matrix of said structure is arranged the stairstepping of convex arc section beyond its most loading ends, though this design can provide the light direction of most led light source modules to be the radiation state, reaches the function that increases its field of illumination.

But, the luminous intensity distribution angle design that this high-power LED street lamp matrix provides the led light source module to be provided with, promptly most individual loading ends are with respect to the monoblock type spline structure of matrix, and most the relative to each other distribution shapes of loading end, can possess best light distribution effect, remain to be discussed.The loading end that mainly will be evagination because of the matrix of this high-power LED street lamp, with the center symmetric mode is set, at the maximum total angle of the bright dipping normal direction line of two the 3rd loading ends in 120 ° scope, separate into six loading ends again, there is each adjacent loading end angle excessive, intersection area is very few to each other for the peripheral light direction of the led light source module that easily causes each loading end and installed, and the illumination defective of light area brightness disproportionation is arranged.

In addition, another relevant high efficiency LED modulated structure with high-power effect, as the high efficiency LED lamp device of TaiWan, China letters patent case M32543 number, it comprises: lamp socket, inside has the formed light trough that caves inward, and the front and back end on the long limit of this light trough bends inwards and is skewed; And two or more lamp groups, be equipped with two or more light emitting diodes in each lamp group, this lamp group is arranged and is formed three rows along the light trough minor face, about row's lamp group according to this light trough inner edge surface and slope inwardly, and be located at row and also slope inwardly with the lamp group of rear end.

The TaiWan, China patent case of above-mentioned announcement, for lamp socket designs being become the tool light trough that caves inward, this light trough is mainly set, all be the state that slopes inwardly in its long front and back end, limit and minor face both sides, and the minor face in the qualification light trough can be organized altogether and establish three bank light groups, and aforementioned each bank light group constitutes by most single lamp groups.

The technical utilization of aforementioned structure is the light trough of concave shape in the lamp socket setting, and then make group be located at three bank light groups in the light trough to present middle bank light group based on the light trough center, the side bank light group that the angle of inclination is arranged to bilateral symmetry, this provides the optical angle design of light source irradiation, though can produce the crossover effect by the light direction of three bank light groups, reach the illuminating effect of its light area of effective lifting; Yet this holder structure still has following improvement place for the treatment of.

This case lamp socket provides the assembling of three bank lights to establish, based on the position in field of illumination that middle bank light group is throwed, both sides bank light group is then had a booster action, in the field of illumination of bank light group, the field of illumination that produces with bank light group in the middle of improving had the more effect of high brightness in the middle of the light zone of being throwed mainly overlapped; Yet, if see it with the high efficiency LED lamp device of integral body, the light source projects zone of this both sides bank light group then, it is overlapping that the outermost field of illumination that is positioned at high efficiency LED lamp device obviously is not subjected to the projection of other bank light group, therefore, in the whole effective lighting zone that produces, exist intermediate illumination zone briliancy strong excessively, peripheral field of illumination presents the problem of the bad luminous intensity distribution of halation state.
