Influence of Encapsulated Silica Gel on Output Luminous Flux of Deep Sea LED Light Source
The LED light source module applied in the deep sea environment adopts encapsulated silica gel as the pressure compensation structure medium
which has the advantages of convenient assembly and simple structure compared with the traditional hydraulic compensation structure. According to the law of refraction(Snell's Law)
the difference in the refractive index of different encapsulated silica gel will lead to different angles of total reflection of light in the sapphire lens window
thus affecting the light flux. Therefore
this paper explores the influence of different refractive index (1.41 to 1.55) and different thickness(1.6 mm to 3.0 mm) of encapsulated silica gel on the output light flux of the light source module. Tracepro simulation results show that the optical flux increases with the decrease of the refractive index of encapsulated silica gel. When the silica gel refractive index is fixed and the package thickness is 2.5 mm
the luminous flux of the light source reaches the maximum. At the same time
this paper designs the silica gel encapsulation experiment. The experimental results are consistent with the simulation results
further verifying the accuracy of the simulation results.
