Refer to shown in Fig. 1 to Fig. 4, the illumination module 100 that the utility model preferred embodiment provides a kind of lighting 200 and is contained in this lighting.Lighting 200 comprises illumination module 100, contact with illumination module 100 arrange radiator 6, illumination module 100 and radiator 6 accommodated housing 7 in the inner and face shield 3.
Illumination module 100 comprises light source module 1 and optical element 2.Light source module 1 comprises plate-shaped light source substrate 10, is integratedly respectively arranged at some LED light sources 11 on light source substrate 10 and drives module 12.In the utility model preferred embodiment, light source substrate 10 is preferably printed circuit board (PCB) (PCB), is provided with circuit in it, simultaneously with LED light source 11 and drive module 12 to realize being electrically connected.In the utility model preferred embodiment, LED light source 11 and driving module 12 are connected for SMD with light source substrate 10, and therefore cost is low, and structure is simple, and integrated level is high.In the utility model preferred embodiment, LED light source 11 is four and dense arrangement, and it is attached on light source substrate 10, thus can encapsulation process be reduced, and reduce costs, but its quantity is not limited to the above, LED light source 11 is preferably no less than two.Drive that module 12 is integrated is arranged on light source substrate 10, and be electrically connected with the interior circuit arranged of light source substrate 10, preferably, module 12 is driven to be arranged at the side of light source substrate 10, the opposite side of light source substrate 10 is provided with power lead 5, and it is same is electrically connected with light source substrate 10, as welded, thus is formed is electrically connected with driving module 12, external power arrives by power lead 5 and drives module 12 and driving driving module 12 is powered for LED light source 11.
Incorporated by reference to consulting Fig. 5 to Fig. 7, optical element 2 is that the lens of integral type form or combined by some lens modules, and it is hybrid lens, has the light in part 21 along short transverse arrangement and light out part 22.This optical element 2 one end (free end of light in part 21) is positioned on light source module 1, and the other end (light out part 22 position place) abuts with face ring 3 inner surface, and namely optical element 2 is folded between light source module 1 and face ring 3.Light in part 21 to cover at above light source board 10 and receives the emergent light of LED light source 11 and carry out optical arrangement to it, and the light in part 21 that described driving module 12 is arranged at optical element 2 is peripheral.Light in part 21 transversely direction (direction vertical with short transverse) can be divided into three regions: be positioned at middle part also just to the central refracting sphere 210 below LED light source 11 and the total internal reflection district 212 being symmetricly set in these refracting sphere 210 both sides, namely this total internal reflection district 212 is around being arranged at refracting sphere 210 periphery.Refracting sphere 210 bottom surface (in the face of the surface of LED light source 11) is (i.e. described horizontal direction in the horizontal direction, it is vertical with described short transverse) plane of incidence 2101 that extends, its width W is preferably not less than the maximum luminous diameter (non-label) of LED light source 11, but in other embodiments, this width W also can be less than the maximum luminous diameter of LED light source 11.Incorporated by reference to consulting Fig. 5, the emergent ray of single LEDs light source 11 is divided into two parts respectively through optical element 2, wherein a part of emergent ray (with the part through the center line C angle behind the center of LED light source 11 being θ 1) is after plane of incidence 2101 incidence, refraction occurs this refracting sphere 210 of process thus from light out part 22 directly outgoing, this part emergent light is non-aligned light.Total internal reflection district 212 is that the different tooth-like part 2120 of height is formed, and tooth-like part 2120 quantity is no less than 2, is preferably 3, and edge is away from center refracting sphere 210 direction, and it increases highly gradually, namely nearer along short transverse distance light source board 10.Therefore, along in short transverse, refracting sphere 210 apart from LED light source 11 farthest, thus closest to the surface at light out part 22 place.And tooth-like part 2120 edges in total internal reflection district 212 move closer to LED light source 11 away from the direction of center refracting sphere 210, and all than refracting sphere 210 closer to LED light source 11.Refer to Fig. 5, the other a part of light of LED light source 11 (be the part of θ 2 with horizontal line angle) is incident from the bottom surface in the total internal reflection district 212 being positioned at refracting sphere 210 both sides respectively, after reflecting after this total internal reflection district 212 is totally reflected from light out part 22 outgoing, this some light becomes collimated ray behind total internal reflection district 212.But, although LED light source 11 is close-packed arrays, be electrically connected to weld with the solder joint on light source substrate 10 to be formed and avoid producing short circuit phenomenon, certain distance is there is between adjacent two LEDs light sources 11, in the utility model preferred embodiment, this distance is defined as minimum range d, and this minimum range d is more than or equal to 1.2mm usually.Refer to Fig. 8 and Fig. 9, it illustrates applicant in R&D process, after have employed the optical element 2 ' of the center refracting sphere 210 ' with curved surfaces or free form surface, LED light source 11 due to the existence of this distance d, its light path and imaging.The emergent ray of LED light source 11 creates imaging phenomenon through optical element 2 ', namely emergent light a ', the b ' of adjacent two LEDs light sources 11 are after the center refracting sphere 210 ' of optical element 2 ', are collimated then from light out part outgoing respectively by this center refracting sphere 210 '.But can clearly see from Fig. 8 and Fig. 9, emergent light a ', the b ' of adjacent two LEDs light sources 11 are owing to having certain distance d, separated from one another after light out part collimation, therefore create imaging phenomenon, as shown in Figure 9.Four LEDs light sources 11 constitute petal hot spot imaging, and this has had a strong impact on the performance of lighting.And, the central refracting sphere 210 of the plane of incidence 2101 with level adopted in the utility model preferred embodiment, incorporated by reference to consulting Fig. 6 to Fig. 7, it is non-aligned light in light out part 22 outgoing after emergent light a, b of spaced LED light source 11 being reflected, this two parts emergent light a, b farthest overlap each other, effectively eliminate imaging phenomenon, define complete hot spot (as shown in Figure 7), greatly improve the light efficiency of lighting.In addition, in order to realize uniform in light emission, light out part 22 is provided with micro-structural (not shown).In other preferred embodiments, optical element 2 for some lens modules combine time, center refracting sphere 210 and total internal reflection district 212 can be made up of independent lens respectively, then mutual around composition optical element 2 of the present utility model.
