Problems solved by technology

[0004] However, light has characteristics such as scattering and reflection. When the scattered light or reflected light of different light falls within the detection range together, it is easy to cause abnormal detection results and it is difficult to complete the detection.
In addition, in order to cooperate with the optical path design of multiple light-emitting diodes, it is difficult to reduce the product size of the light source device, and it is impossible to achieve the purpose of thinning the detection instrument, and it is also difficult to design a handheld detection instrument

Abstract

The invention provides a multi-spectrum light source device. The multi-spectrum light source device comprises a substrate, a plurality of light emitting diodes, a cover body and a light guide body. The plurality of light emitting diodes are arranged on the substrate and respectively emit a plurality of waveband lights with different wavelengths, the cover body is arranged on the substrate and covers the plurality of light emitting diodes, and the light guide body is arranged on the substrate and is provided with a light guide outlet, wherein the substrate has a first diameter, the light guideoutlet has a second diameter, and the value of the length ratio of the first diameter to the second diameter ranges from 9 to 15, so that the light of multiple wave bands advances, is focused in the light guide body and is emitted out from the light guide outlet. Therefore, the light projection position can be accurate, the detection environments are the same, the abnormal detection results causedby scattering or reflection are avoided, and the detection effect is optimized. Meanwhile, a product can be miniaturized, and a handheld detection instrument is achieved.

Description

technical field [0001] The invention relates to a light source device, in particular to a multi-spectrum light source device. Background technique [0002] As a light source, light-emitting diodes are widely used in various detection instruments, such as skin condition detection devices, due to their stable light emission and low energy consumption. Generally speaking, when using a light source device for testing, the light source is usually placed on the surface to be tested, and the reflected light is detected to obtain information. [0003] When it is desired to detect light of multiple different wavelengths, the light source device is often equipped with multiple light emitting diodes capable of emitting light of different wavelengths, and cooperates with the optical path design to emit such light onto the surface to be tested for detection. [0004] However, light has characteristics such as scattering and reflection. When the scattered light or reflected light of diff...
