本发明公开了一种降低蓝光危害的COB光源器件，包括基座和串联设置在基座的第一芯片组、第二芯片组，第一芯片组包括多个发光范围为465nm～470nm的蓝光芯片，第二芯片组包括多个发光范围为440nm～470nm的蓝光芯片，第二芯片组通过设置并激发黄绿色荧光粉和红色荧光粉获得绿光和红光，并与第一芯片组的蓝光芯片发射的蓝光混合形成白光，其中，第一芯片组的蓝光芯片的数量大于第二芯片组的蓝光芯片的数量。通过在底座设置第一芯片组、第二芯片组，第一芯片组中发光范围为465nm～470nm的蓝光芯片的数量大于第二芯片组中发光范围为440nm～470nm的蓝光芯片，使得形成的白光中以第一芯片组为主，低于460nm的蓝光被削弱或消除，降低蓝光危害，而该光源参数性能以及性价比与紫光相比较具有更高的优势。

The invention discloses a COB light source device for reducing the harm of blue light, which comprises a base and a first chipset and a second chipset arranged in series on the base. The first chipset comprises a plurality of blue light chips with a luminescent range of 465nm ~ 470nm, and the second chipset comprises a plurality of blue light chips with a luminescent range of 440nm ~ 470nm. The second chipset obtains green and red light by setting and exciting the yellow-green and red phosphors, and mixes with the blue light emitted by the blue light chip of the first chipset to form white light, wherein the number of blue light chips in the first chipset is greater than the number of blue light chips in the second chipset. By setting the first chipset and the second chipset in the base, the number of blue chips with the luminescence range of 465nm-470nm in the first chipset is greater than that in the second chipset with the luminescence range of 440nm-470nm, so that the white light formed is dominated by the first chipset, and the blue light lower than 460nm is weakened or eliminated to reduce the harm of blue light. Compared with purple light, the parameter performance and cost performance of this light source have higher advantages.
