The configuration of the light source substrate 2 on the horizontal surface is substantially the same as that of the lens 1 and has a circular spiral shape, and is an integrated structure. Specifically, the light source substrate 2 includes a central driving power supply unit 22 and a self-driving power supply unit 22 extending to A spiral light source unit 21. The driving power source accommodating portion 12 covers the driving power source portion 22, and the optical portion 11 covers the light source portion 21. The light source substrate 2 can be fixed to the optical portion 11 of the lens 1 through a snap element (not shown) on the optical portion 11 of the lens 1. When the connecting portion 13 is an optical region for light distribution, the light source substrate 2 may further include a portion (not shown) corresponding to the connecting portion 13, and thus, the connecting portion 13 may also emit light for the light source substrate 2.
驱动电源组件(未图示)安装于光源基板2的内侧端且位于透镜1的收容槽1211内,其包括设于光源基板2的一侧表面的若干元器件,包括但不限于驱动控制器芯片、整流芯片、电阻器、电容器、保险丝和线圈等,以表面贴设或插件的形式将若干元器件设置在光源基板2上。在其它可替换的实施例中,光源模组30内也可以另设电源基板,用于安装驱动电源组件,并且电源基板与光源基板2之间电性连接。A driving power supply unit (not shown) is mounted on the inner end of the light source substrate 2 and located in the receiving groove 1211 of the lens 1. The device includes a plurality of components disposed on one surface of the light source substrate 2, including but not limited to a driving controller chip. A rectifier chip, a resistor, a capacitor, a fuse, a coil, and the like are disposed on the light source substrate 2 in the form of a surface mount or a plug. In other alternative embodiments, a power supply substrate may be additionally disposed in the light source module 30 for mounting the driving power supply component, and the power supply substrate and the light source substrate 2 are electrically connected.
发光单元3为LED发光单元,其可以通过表面贴装工艺(Surface Mount Technology,SMT)或插入式封装技术(Through Hole Technology,THT)被安装在光源基板2的上表面。通过光源基板2上的导电线路,若干发光单元3之间相互电性连接。若干发光单元3沿光源部21的延伸方向依次排列。需要说明的是,若干发光单元3置于光学部11的下方且与凹陷槽111相对应,即发光单元3可以视为收容于凹陷槽111内。当然,作为本发明其他可替换的实施方式,单排的若干发光单元3还可以偏心设置,也可以设置两排或者三排或者更多排的发光单元3。The light emitting unit 3 is an LED light emitting unit which can be mounted on the upper surface of the light source substrate 2 by Surface Mount Technology (SMT) or Through Hole Technology (THT).

需要说明的是,光源模组30可以应用于照明装置100。当照明装置100启动后,光源模组30内的发光单元3所发出光线通过透镜1的光学部11的光入射面后发生一次向外折射,光线在透镜1的光学部11内沿直线延伸,当光线抵达光出射面后发生二次向外折射,经过两次向外折射后使得光源模组30的光照角度被加大。相对于现有技术,在保持照明装置100原有亮度的情况下,光源模组30内的承载发光单元3的光源基板2的尺寸可以缩小,发光单元3的数量也可以减少,从而降低了光源模组30的制造成本。另外,由于驱动电源组件可以安装于光源模组30的光源基板2上并收容于透镜1的收容槽1211内,使得光源模组30的光源基板2的空间得到充分利用,这样,集成了驱动电源组件的光源模组30就可以作为一个模块而组装至照明装置100内。同时,光源模组30上的透镜1也作为电气绝缘壳体,提高了安全等级。It should be noted that the light source module 30 can be applied to the illumination device 100. After the illumination device 100 is activated, the light emitted by the light-emitting unit 3 in the light source module 30 passes through the light incident surface of the optical portion 11 of the lens 1 to be outwardly refracted, and the light extends in a straight line in the optical portion 11 of the lens 1. When the light reaches the light exit surface, a secondary outward refraction occurs, and after two outward refracting, the illumination angle of the light source module 30 is increased. Compared with the prior art, in the case of maintaining the original brightness of the illumination device 100, the size of the light source substrate 2 carrying the light-emitting unit 3 in the light source module 30 can be reduced, and the number of the light-emitting units 3 can also be reduced, thereby reducing the light source. The manufacturing cost of the module 30. In addition, since the driving power supply unit can be mounted on the light source substrate 2 of the light source module 30 and housed in the receiving groove 1211 of the lens 1 , the space of the light source substrate 2 of the light source module 30 is fully utilized, thus integrating the driving power source. The light source module 30 of the assembly can be assembled into the lighting device 100 as a module. At the same time, the lens 1 on the light source module 30 also serves as an electrically insulating housing, which improves the safety level.
最值得注意的是,本发明提供的光源模组30内,其内的光源基板2为一体式结构,方便组装,相对于拼接式的结构降低了制造成本;光源基板2呈螺旋状,在制造光源基板时,在一块印刷电路板上切除了一个螺旋状的基板后,剩余的部分还可以再切成一个或者多个螺旋状的基板,如此可以尽量减少了制造光源基板后余料的产生,节省了光源基板的制造成本。Most notably, in the light source module 30 provided by the present invention, the light source substrate 2 is an integrated structure, which is convenient for assembly, and reduces manufacturing cost compared with the spliced structure; the light source substrate 2 is spiral, and is manufactured. In the case of the light source substrate, after cutting a spiral substrate on a printed circuit board, the remaining portion can be further cut into one or more spiral substrates, so that the generation of residual materials after the light source substrate is manufactured can be minimized. The manufacturing cost of the light source substrate is saved.
