Hot photoresistance has concave structure every reflector 23, is formed at printed circuit board (PCB) 21 surfaces.Hot photoresistance is provided with an illuminating source 22 in the spill of reflector 23, and the axial ray direction of advance that illuminating source 22 sends is corresponding to the uncovered part of hot photoresistance every reflector 23.Hot photoresistance is a reflecting surface every the inner surface of reflector 23.Have the uncovered light-emitting window that can be used as illuminating source 22 of the hot photoresistance of concave structure every reflector 23, this uncovered concrete shape and big I design according to actual needs, are shaped as square or circle etc. as hot photoresistance every reflector 23 uncovered.
This hot photoresistance is the heat radiations that stop and reflect non axial light beam generation in illuminating source 22 outgoing beams every the effect of reflector 23, and the heat radiation that makes non axial light produce can not produce heat effect to illuminating source packaging structure.This non axial invalid light comprises the side direction light of illuminating source 22 outgoing and the light of close printed circuit board (PCB) 21 directions.
White space between light conductor 24 and printed circuit board (PCB) 21 is filled with transparent resin 25, and transparent resin 25 is used to protect illuminating source 22.Transparent resin 25 is filled in the zone between light conductor 24 lower surfaces and printed circuit board (PCB) 21, and be limited in simultaneously hot photoresistance every reflector 23 in the zone that illuminating source 22 forms, promptly all be filled with transparent resin 25 every illuminating source 22 edges and top that reflector 23 centers on by hot photoresistance.
The present embodiment illuminating source packaging structure, by illuminating source being laid in hot photoresistance in the spill of reflector, hot photoresistance is a reflecting surface every the inner surface of reflector, promptly this hot photoresistance is a reflecting surface every the reflector surface adjacent with illuminating source, this makes that working as illuminating source sends non axial invalid light, hot photoresistance can reflex to these non axial invalid light outside the illuminating source packaging structure every reflector, thereby help improving the optical stability of illuminating source packaging structure, and reduce the castering action of the optical radiation of non axial invalid light illuminating source packaging structure self temperature; Simultaneously, illuminating source packaging structure of the present invention also helps non axial invalid light is changed into the contributive effective sunlight of the whole luminous illumination of light source, thereby helps improving the electro-optical efficiency of illuminating source packaging structure.
Fig. 3 is the illuminating source packaging structure second example structure schematic diagram of the present invention.Present embodiment shows and comprises a plurality of illuminating sources and a plurality of illuminating source packaging structure with hot photoresistance of concave structure every reflector on basis embodiment illustrated in fig. 2.As shown in Figure 3, in the present embodiment, each hot photoresistance is provided with an illuminating source 22 in reflector 23 spills, and the axial ray direction of advance that illuminating source 22 sends is corresponding to the uncovered part of hot photoresistance every reflector 23.
For ease of explanation present embodiment technical scheme, a hot photoresistance is provided with axial ray direction of advance that an illuminating source 22 and illuminating source 22 send corresponding to the structure of hot photoresistance every the uncovered part of reflector 23 in reflector 23 spills, is called an effective luminescence unit.A plurality of effective luminescence units are arranged with matrix, like this, have isolated mutually every reflector 23 by hot photoresistance between the adjacent illuminating source 22.Light conductor 24 is located at a plurality of illuminating sources 22 and a plurality of hot photoresistance every reflector 23 tops, and the white space between light conductor and printed circuit board (PCB) 21 is filled with transparent resin 25.
In the present embodiment, hot photoresistance with concave structure is reflecting surface every the inner surface of reflector 23, the instant heating photoresistance is reflecting surface every reflector 23 and illuminating source 22 each adjacent surface, concrete, hot photoresistance is a sideswipe face 231 every the side of reflector 23 inner surfaces, and hot photoresistance is the horizontal reflection face 232 adjacent with illuminating source 22 bottoms every the lower surface of reflector 23 inner surfaces.Printed circuit board (PCB) 21 includes the electrode pads 26 that is used to locate illuminating source 22.Illuminating source 22 is arranged on the horizontal reflection face 232, and is electrically connected with printed circuit board (PCB) 21 by electrode pads 26.
On the basis of present embodiment technical scheme, hot photoresistance designs according to actual needs every the uncovered concrete shape and the big I of reflector 23.Fig. 4 is the illuminating source packaging structure schematic diagram of honeycomb arrangement of the present invention.As shown in Figure 4, hot photoresistance can be circle every the uncovered shape of reflector 23, illuminating source packaging structure has the circular uncovered hot photoresistance of concave structure to be arranged every reflector 23 and a plurality of effective luminescence unit matrix that illuminating source 22 is formed, thereby forms the illuminating source packaging structure that is honeycomb arrangement.The illuminating source packaging structure schematic diagram that Fig. 5 arranges for square matrix of the present invention.As shown in Figure 5, hot photoresistance can be square every the uncovered shape of reflector 23, have the square uncovered hot photoresistance of concave structure and arrange, be the illuminating source packaging structure that the square matrix is arranged thereby form every reflector 23 and a plurality of effective luminescence unit matrix that illuminating source 22 is formed.In addition, hot photoresistance designs according to actual needs every the uncovered big I of reflector 23.
In order to make heat rejection reflector 23 can effectively stop the light that to inject the light-emitting window position of adjacent illuminating source correspondence in the parallel component of illuminating source 22 outgoing beams, avoid illuminating source 22 parallel components that adjacent illuminating source 22 is produced the light interference effect, the spill degree of depth of heat rejection reflector 23 is more than or equal to the height of illuminating source 22.In order to make heat rejection reflector 23 can effectively stop and reflect side direction in illuminating source 22 outgoing beams and near the heat radiation of printed circuit board (PCB) 21 directions, make these radiation to the whole heat effect that produces of adjacent illuminating source 22 and illuminating source packaging structure, hot photoresistance every the angle of the sideswipe face 231 of reflector 23 inner surfaces and printed circuit board (PCB) 21 greater than 90 °.Further, hot photoresistance can be plane, cancave cambered surface or convex globoidal every the sideswipe face 231 of reflector 23.In the actual design of illuminating source packaging structure, by carrying out of the adjustment of hot photoresistance every sideswipe face 231 surface configurations, curvature, surface area and the surface reflectivity of reflector 23, the non axial invalid light of outgoing in the illuminating source 22 can be reflected outside the illuminating source packaging structure, thereby effectively reduce the illuminating source packaging structure bulk temperature, improve electro-optical efficiency; Also can be controlled simultaneously the output beam angle of divergence.
