碩士 === 國立臺北科技大學 === 製造科技研究所 === 100 === We use the graphic program－Labview,which developed by National Instrument to progress this homemade platform control system and human machine interface design.；with three hardware－the programmable logic controller that made by Mitsubishi,the temperature sensor that made by Advantech,the Illuminance sensor (with±2% Accuracy)that made by Konica Minolta and the linear guideway and ballscrew that made by HIWIN technology,the stepping motor and reducer mechanism that made by Troy Enterprise Company,and follow CNS standard(include CNS 5119 C4165 Illuminance Meters、CNS 5065 C3069 Methods of Illumination Measurements、CNS 12112 Z1044 Lighting of indoor work places、CNS15249 C3222 Methods of measurement on light emitting diode components for optical and electrical characteristics、CNS 15437 C4510 Recessed LED luminaires for T-bar ceiling systems、CNS15233 C4504 Fixtures of roadway lighting with light emitting diode lamps) to build the LED automatic measuration platform which have Auto/Manual mode,the human machine interface possess the measuration of illuminance (the maximum/minimum value、the average illuminance value、the uniform illuminance value、the illuminance plat/space distribuction),the calculate of light intensity,the simulation of LED chip temperature feature.The machine system accurate at X-axis have 0.263mm deviation,on the orther hand,at Y-axis have 0.194mm deviation. Because of the 80% input power of LED will transfer to thermal,that the platform also include on-time temperature monitor system. Through temperature simulate identify system [17、23] that developed by micro thermal-fluid labatory,we use this model integrat to Labview program and with the temperature on lamp board(Tb),to simulate the chip central temperature(Tj).With Tj,we can find out that temperature raise status when lamp turn on.The simulation of LED chip temperture is the platform others feature. Due to the Light-emitting Diode rapid developed in recent years,that its apply in various application,the solid lighting became into our daily life, such as traffic light, light crystal panel,the product of communicate,that into building, medical, and the lighting of landscape. Because of the various extend application, the CNS 12112 Z1044 standard base on different occasion to establish the necessary illuminance value(lux),that provide a reference to cosumer. We use this homemade machine which have the measurement of illuminance function to test a total of 27 various lamp,include the lamp at market that can purchase and the LED lamp,we can campare the testing result and give recommend about energy-saving issue. This machine is the only Automatic illuminance measuration/temperature simulate platform nowadays in the world.But the measure height still have restriction,therefore,it can increase the measuration height and test more species lamp,and can assort with the terminal consumer to provide more optics mesuration soluction is the platform prospect for the future.
