一种用于曝光机的双LED平行光源机构
摘要：
本发明公开了一种用于曝光机的双LED平行光源机构，包括第一反光镜和第二反光镜，光源采用LED光源，包括有两组LED光源，即第一LED光源模组和第二LED光源模组，其中第一LED光源模组朝向第一反光镜，第二LED光源模组朝向第二反光镜。本发明通过采用两组LED光源，两组光源均设置在距离反光镜较近的位置直接照射反光镜，省去了中间过渡的平面光镜，从而可以将光照强度提高两倍以上，而曝光效率则可以提高3倍以上，如完成同样一框线路板的曝光时间仅为5秒，一周用电量仅为两百多度，降低了75%以上；另外，整个设备的安装结构相当简单，安装成本降低50%左右，对于照射角度的调节也方便了很多。
摘要（英）：

The invention discloses a double parallel LED light source mechanism for an exposure machine. The double parallel LED light source mechanism comprises a first reflector and a second reflector, wherein LED light sources are adopted by a light source; the light source comprises two groups of LED light sources, namely a first LED light source module and a second LED light source module; the first LED light source module is toward the first reflector; and the second LED light source module is toward the second reflector. Through the adoption of two groups of LED light sources, the two groups of light sources are arranged at the positions closer to the reflectors for directly irradiating the reflectors and a middle transition plane light mirror is omitted, so that the illumination intensity can be improved by over twice, the exposure efficiency can be improved by over three times, and if the exposure time for completing a same frame circuit board is only 5 seconds, the weekly power consumption is only more than 200 kilowatt-hours and is reduced by over 75%. Furthermore, an installation structure of the whole equipment is extremely simple, the installation cost is reduced by about 50% and adjustment of the irradiation angles is also greatly facilitated.
