[0020] 请参考图1至图3,该配光件30包括配光部31及与该配光部31热连接的传热部32,该传热部32设置于该灯头体10的顶部,用于支撑该配光件30且将该发光件40产生的热量传递到该灯头体10上。 [0020] Please refer to FIG. 1 to FIG. 3, the light distribution member 30 includes a light distribution portion 31 and the light distribution portion 31 thermally connected to the heat transfer portion 32, the heat transfer portion 32 is provided at the top of the cap body 10, for supporting the light element 30 and the body 10 passes the heat generated by the light emitting element 40 to the cap. 该传热部32的一端设有与该配光部31连接的支架,该配光部31为透镜结构,该配光部31由透明或半透明材料制成。 One end of the heat transfer portion 32 is provided with light distribution portion 31 is connected to the holder, the portion 31 of the light distribution lens structure, the light distribution portion 31 is made of a transparent or translucent material. 该配光部31为环形结构,该配光部31的横截面为圆心角大于180度的扇形结构(如图3所示),以便对照射到其上的光进行折射,使得更多的光线射向该灯泡壳20的底部。 The light distribution portion 31 is an annular structure, the cross section of the light distribution portion 31 is greater than a central angle of 180 degrees sector structure (shown in Figure 3), in order to control the light incident on it is refracted, so that more light fired the shell at the bottom of the bulb 20. 该配光部31与该传热部32均由具有良好导热或散热能力的材料制成。 The light distribution by 31 and 32 material with good thermal or cooling capacity of the heat transfer section is made. 该配光部31包括安装面311及出光面312 (如图3所示)。 The light unit 31 includes a mounting surface 311 and exit surface 312 (Figure 3). 该安装面311位于该配光部31的底面,且该配光部31的底面面积大于该发光件40的基板41的面积。 The mounting surface 311 is located at the bottom surface of the light distribution portion 31, and the light distribution portion 31 is larger than the area of the bottom surface 40 of the substrate 41 in the area of the light emitting member. 该安装面311位于该配光部31朝向该灯头体10的侧边上,该出光面312朝向该灯泡壳20设置。 The mounting surface 311 is located on the light side portion of the cap body 31 toward 10, the exit surface 312 toward the lamp housing 20 is provided. 该配光部31将该发光件40发出的光更多地朝向该灯泡壳20的底部折射,以便照亮该灯泡壳20的底部。 40 of the light emitted from the light emitting member 31 more toward the bottom of the bulb housing 20 of refraction so as to illuminate the bulb housing bottom 20. 该发光件40与该配光部31的安装面311热连接,该安装面311上设有收容槽313,该基板41固定在该安装面311上,该基板41与该安装面311之间通过导热介质热连接,且其上的LED光源42收容在这些收容槽313内。 The light emitting element 40 is connected to the mounting surface 311 with a thermo-optical portion 31 with receiving groove 313 on the mounting surface 311 of the substrate 41 is fixed to the mounting surface 311 of the substrate 41 between the mounting surface 311 and through heat transfer medium is thermally connected, and the LED light source 42 on which is housed in the storage tank 313 of these. 这些收容槽313内设有导热材料35,这些LED光源42发出的热量通过该导热材料35传递到该收容槽313上,该导热材料35为液态或固态的透明或半透明材料。 The storage tank 313 equipped with a thermally conductive material 35, the heat emitted from the LED light source 42 passes through the thermally conductive material 35 to the storage tank 313, the thermally conductive material 35 is a liquid or solid transparent or translucent material. 优选为液态材料,因为液体的导热性能极好,能将该LED光源42表面的热量快速传递到该配光部31上。 Preferably a liquid material because excellent thermal conductivity of the liquid, can quickly transfer the heat surface of the LED light source 42 to the light unit 31. 该配光件30上设有透光散射材料,这些LED光源42发出的光经过散射,使得该LED灯100的发光曲线分布更均匀。 This feature is provided on the light scattering member 30 light-transmitting material, light scattering through the LED light source 42 emitted luminescence curve so that the LED lamp 100 more evenly distributed.

[0021] 工作时,这些LED光源42发出的光经该配光部31的发散作用而照亮该灯泡壳20,这些LED光源42产生的一部分热量被该收容槽313内的导热材料35及时传递到该配光部31上,另一部分热量经由与该基板41热连接的安装面311传递到该配光部31上,该配光部31的热量经由与其热连接的传热部32传递到该灯头体10上,从而将热量及时散发到外部空间。 When the [0021] work, the light emitted from the LED light source 42 by action of the diverging portion 31 and the light illuminating the lamp housing 20, a portion of the heat generated by the LED light source 42 is a thermally conductive material 313 within the receiving groove 35 timely delivery to the light unit 31, another part of the heat via the mounting surface of the substrate 41 is thermally connected to the 311 passes light distribution portion 31, the heat of the light distribution portion 31 of the heat transfer portion is thermally connected thereto is transmitted to the via 32 the cap body 10, which will be distributed in the heat to the outside space.

[0022] 综上所述,该外向散热LED灯100设置了配光件30,该发光件40的LED光源42设置在该发光件40的基板41与该配光件30热连接形成的收容槽313内,该收容槽313内填有导热材料35对这些LED光源42的外表进行全方位的散热,且将这些LED光源42产生热量及时传递到该配光件30上,及时将热量散发出去,从而避免热量的堆积;另一部分热量由该基板41传递到与其热连接的配光件30上,该配光件30上的热量由该配光件30的传热部32传递到该灯头体10上将热量散到外部空间。 [0022] In summary, the outgoing heat LED lamp 100 is provided with a light guide 30, the light-emitting element LED light source 42 of the light emitting element disposed on the substrate 40, 41 connected to the light receiving element 30 hot forming groove within 313, filled with a thermally conductive material 35 of these LED light look 42-round heat, and the LED light source 42 generates heat which promptly transmitted to the light 30, in a timely manner within the heat out of the storage tank 313, thereby avoiding the accumulation of heat; another part of the heat transferred from the substrate 41 to the light 30 is thermally connected thereto, which with the heat on the optical element 30 delivered by the light element 30 to the heat transfer portion 32 of the cap 10 Heat will be dissipated to the outside space. 这样,由于该外向散热LED灯100无需设置较大的散热立柱和PCB板,就能够对这些LED光源42产生的热量进行全方位的散热,使得该外向散热LED灯100具有散热及时、轻便的优点。 Thus, since the LED light radiating outward 100 without providing larger heat columns and PCB board, it is possible for the heat generated by the LED light source 42-round heat, so that the outward radiating LED lamp 100 has a cooling timely and lightweight advantages .

[0023] 由于该安装面312位于该配光部31的底面,且该安装面312的面积大于该基板41的面积,使得该安装面312不会被该基板41遮挡,光线可以从该安装面312射出,照向该灯泡壳20的底部。 [0023] Since the mounting surface 312 is located in the bottom surface of the light distribution portion 31, and the area of the mounting surface 312 is larger than the area of the substrate 41, such that the mounting surface 312 of the substrate 41 is not blocked, the light from the mounting surface 312 exit, according to the lamp housing bottom 20. 另外,由于该基板41由透明材料制成,该LED光源42发出的光可以直接穿过该基板41向该灯泡壳20的底部发射。 Further, since the substrate 41 is made of a transparent material, light emitted from the LED light source 42 can pass through the bottom of the substrate 41 to the housing 20 of the lamp emission. 这些LED光源42发出的光经该配光件30配光部31的发散,照亮该灯泡壳20的顶部、侧壁及底部从而实现大角度发光。 After the light diverging light 30 light distribution portion 31, top, side walls and a bottom shell illuminating the bulb 20 so as to achieve a large point of light emitted from the LED light source 42. 之所以将该配光部31的横截面设置为圆心角大于180度的扇形结构,并将该安装面设置在该配光部31朝向该灯头体10的侧边上,是因为我们发现,LED光源42发出的光线将被更多的朝向透镜比较厚的部位折射。 The reason why the light section 31 of the cross-section is set to be greater than a central angle of 180 degrees sector structure, and the mounting surface is provided on the light side portion of the cap body 31 toward the 10, because we found, LED the light emitted from the light source 42 will be more toward the relatively thickest part of the refractive lens. 与现有技术相比,由于无需在散热立柱上设置多个PCB板且在每个PCB板上焊接LED芯片就能实现大角度发光,使得该外向散热LED灯100还具有组装方便的优点。 Compared with the prior art, since a plurality of the PCB without cooling column on the PCB and soldered in each LED chip emitting a large angle can be realized, so that the outward radiating LED lamp 100 also has the advantages of easy assembly.

[0024] 进一步的,还可以设计不同的该配光件30配光部31的横截面,只要能够对这些LED光源42发出的光进行二次配光,来达到大角度发光的目的。 [0024] Further, it can be designed with different cross-section of the optical element 30 with light unit 31, as long as the purpose of the light emitted by the LED light source 42 for the second light, to achieve wide-angle light emission.

[0025] 以上这些仅为本发明的较佳实施例而已,并不用以限制本发明,任何本领域人员在不脱离本方案技术范围内,利用上述揭露的技术内容作些许改动的为同等变化的等效实施例。 [0025] These only preferred embodiments of the present invention, it is not intended to limit the present invention, any person skilled in the art without departing from the scope of this program, the use of technology to expose the contents of which are a few changes to make changes to the same equivalent embodiments. 但凡脱离本发明技术方案内容,依据本发明技术实质对以上实施例所做的任何修改、等同替换、改进等,均应包含在本发明保护的范围之内。 Whenever content from the aspect of the present invention, in accordance with any changes to the technical nature of the invention made by the above example embodiments, equivalent replacement and improvement should be included within the scope of protection of the present invention.
