【摘要】：本文介紹了室外LED燈具的可靠性試驗(yàn)項(xiàng)目,分析了MTTF與樣品數(shù)量、置信水平和試驗(yàn)時(shí)間之間的關(guān)系,有助于對(duì)室外LED燈具的聲稱(chēng)壽命進(jìn)行預(yù)先判斷;另外還研究了LED燈具系統(tǒng)可靠度與置信水平、樣品數(shù)量之間的關(guān)系,通過(guò)選擇合適的加速壽命試驗(yàn)項(xiàng)目和樣品數(shù)量,可以比較方便的預(yù)測(cè)出LED燈具的系統(tǒng)可靠度水平。本文的研究結(jié)果可以為準(zhǔn)確評(píng)價(jià)室外LED燈具的可靠性提供一定的技術(shù)支撐,而且為其壽命預(yù)測(cè)做出貢獻(xiàn)。
[Abstract]:This paper introduces the reliability test items of outdoor LED lamps and analyzes the relationship between MTTF and sample quantity, confidence level and test time, which is helpful to prejudge the claimed life of outdoor LED lamps. In addition, the relationship between reliability, confidence level and sample quantity of LED lamps system is studied. By selecting suitable accelerated life test items and sample quantity, The system reliability level of LED lamps can be predicted conveniently. The research results in this paper can provide some technical support for the accurate evaluation of the reliability of outdoor LED lamps and contribute to the prediction of their life.
