Heat dissipation structure and liquid optical waveguide assembly

Abstract

The invention discloses a heat dissipation structure and a liquid optical waveguide assembly. The heat dissipation structure can be arranged on a liquid optical waveguide to dissipate heat of the liquid optical waveguide, and comprises a heat dissipation block provided with an accommodating channel, and a heat dissipation unit arranged in the accommodating channel and attached to the accommodatingchannel, wherein the heat dissipation unit is further arranged to be capable of being attached to the outer diameter of the liquid optical waveguide arranged in the accommodating channel; the heat dissipation block and the heat dissipation unit are both made of heat conduction materials with the heat conductivity higher than the heat conductivity of air; and the heat conductivity of the heat dissipation block is higher than the heat conductivity of the heat dissipation unit. The temperature of the liquid optical waveguide can be transmitted to the heat dissipation block through the heat dissipation unit, and finally heat dissipation of the liquid optical waveguide is realized through temperature exchange between the heat dissipation block and the external environment, so that the problemof liquid core failure or light spot loss of the liquid optical waveguide due to over-high temperature is avoided; and the problem of a poor heat dissipation effect of the heat dissipation structure caused by an air layer between the liquid optical waveguide and the heat dissipation block is solved.

Background technique [0002] When using the liquid light waveguide and optical fiber to guide the light generated by the LED light source or light source group, the position of the output light can be adjusted by adjusting the position of the liquid light waveguide or the output end of the optical fiber without moving the entire light source. Compared with optical fiber or optical fiber bundle, liquid optical waveguide has higher numerical aperture and transmittance; and compared with glass optical fiber, liquid optical waveguide can transmit ultraviolet light. Therefore, liquid optical waveguides have become the mainstream solution for light transmission of LED light sources or light source groups, and are mainly used in the field of high-end light sources such as microscope light sour...

[0003] However, in actual use, it is found that when the light of the LED light source is transmitted through the liquid optical waveguide, the liquid optical waveguide is prone to problems such as liquid core failure, greatly reduced light transmittance, or missing light spots, and the service life is unstable.
