摘要

LED光源作為汽車(chē)照明系統(tǒng)的一門(mén)關(guān)鍵技術(shù), LED汽車(chē)前照燈的配光設(shè)計(jì)是一個(gè)具有挑戰(zhàn)性的研究課題。根據(jù)光通量及色度指標(biāo)的要求選擇LED光源, 采用拋物面反射器并結(jié)合兩者的偏移與旋轉(zhuǎn)來(lái)分析光分布。每個(gè)LED光源擁有獨(dú)立的光學(xué)系統(tǒng), 并負(fù)責(zé)配光屏上不同區(qū)域的照度, 近光系統(tǒng)采用8個(gè)LED, 遠(yuǎn)光系統(tǒng)采用10個(gè)LED。用CATIA三維設(shè)計(jì)軟件畫(huà)出組合反射器模型圖, 通過(guò)光學(xué)軟件Tracepro反復(fù)調(diào)用不同的模型來(lái)追跡光線(xiàn)得到最后的配光效果。設(shè)計(jì)中無(wú)需配光鏡、擋光板以及復(fù)雜的計(jì)算程序, 設(shè)計(jì)周期短、配光效果好, 給出的配光模擬照度值完全符合最新出臺(tái)的GB4599-2007標(biāo)準(zhǔn)。

Abstract

Due to its superior performances such as energy saving and environmental protection, LED is widely used in automotive lighting. As a key technique on automotive lighting system, light distribution design of LED automotive headlamp is a challenging research subject. LED sources were chosen according to the standard, and Light distribution was analyzed by using parabolic reflector under moving and rotating conditions. Each light source has its self-contained optical system and arranges the irradiance of different area on distribute-screen, 8 LED sources were used in low-beam system, and 10 LED sources were used in high-beam system. Combined reflector model was drawn in CATIA software. The final results were achieved by using Tracepro after calling different lens model iteratively. Baffle board and complex calculation program were not required in this design process. This method has short design period and high distribution efficiency. The final illumination results completely conform to the revised standard of GB4599-2007.
