碩士 / 國立臺灣海洋大學 / 機械與機電工程學系 / 103 / In the lights fishery, the ship energy consumes a proportion to has the mainest of equipment for gather a fish light, the tradition gathers the fish lamp existence purple outside and only, surface heat and high energy-consuming problem, as adoption high the power give out light diode(LED) to improve the weakness of traditional lamp. The tradition gathers a fish lamp the center shine on a degree about is a 2500~3000 Lux, in the bright degree of not lost all lamp, Certanly will adopt Gao power LED light to reach it illuminates of need, but will spread out LED over the hot etc. problem.
This research aims at higher - first power LED eliminate heat hot system field analysis, by computing fluid mechanics software Icepak imitate the analysis. The applied limited physical volume method(Finite-volume method) will dominate the equation exploitation control physical volume integral method(Control Volume Integration Approach) and differ the equation convert of the dominating of integral type to divide into a method for the finite, will be partial to the differential equation discrete to turn to solve the problems, such as field and thermal conduction...etc. of the 3D steady state, streaming and imitate its streaming field variety and temperature to distribute the condition. Try to calculate by average illumination formula again, with actual illumination compare to after, change its angle and irradiation area, observation change LED to gather a fish lamp can reach the illumination of gathering the fish lamp need.
Analyze the result to know while analyzing in the single module, effectively change higher - power LED chip to carry the board, electric circuit substrate and heat dissipation interface material, again match to eliminate heat a fin slice to down suggest a little bit as a result with traditional LED light, the chip temperature can descend 32.7% around. For saving cost expense and weight of lamp, this research adopts high power LED of modularity to gather a fish lamp and carries on the single module many mold alignments and lamp to open the hole test and display to adopt 15 modes that module lamp opens the hole B as effect of the best emulations as a result, chip's maximum temperature the degree is just in 78.5 ℃ . Adopt this LED to gather a fish lamp it the total wattage is a 225 Watts, gather a fish lamp to try to calculate its illumination by 6 LEDs, center's biggest illumination can reach to a 2500 Lux, be able to replace the tradition to gather a fish lamp.
