Optical design of a high-mast luminaire based on four COB LED light source modules

Abstract

Light-emitting diodes (LEDs) have been widely used in road lighting. This study investigates the optical design of a high-mast luminaire based on four chips-on-board LED light source modules and applies it to road lighting. The model of the high-mast luminaire is built with Solidworks, and then the optical simulations are analysed by Tracepro and Dialux. We also make a physical prototype of the high-mast luminaire to test its performance in practice. The illuminance distribution of the test area is nearly rectangular. The interior of the rectangle forms a smaller highlighted rectangular illumination area with uniform illumination. The outer edges of the rectangular illumination area will overlap the outer edges of the illumination area of other high-mast luminaires. The desired illuminance distribution and the uniform illumination can be obtained. Both the simulations and the experimental results meet the requirements of road lighting standards and the high-mast lamp can even achieve a better optical performance.

Led source of light with high light circuit

“…Охлаждение производится за счет конвекции. Тепло от светодиода передается на печатную плату, дальше, от печатной платы через теплопроводящий материал, тепло передается на радиатор, где оно рассеивается в воздухе [2,6,10,[14][15][16].…”

M1 ve M2 aydınlatma sınıfı yollar için geliştirilen bir COB LED’li yol aydınlatma armatür modelinin optik tasarımı

“…COB LED'lerin çok çipli yapıları sayesinde küçük bir yüzey üzerine birden çok LED çipi yerleştirmek mümkündür. COB teknolojisine dayalı çözümler ile 10.000 lm'in üzerinde ışık çıkışı elde etmek mümkün olmuştur [32].…”

Design of a high-efficiency system with combined reflectors for a light-emitting diode front fog lamp

“…People's demand for safe driving and highquality illumination is growing with the popularity of light-emitting diode (LED) technology, [1][2][3][4][5] causing many well-known companies and laboratories to struggle with LED vehicle lighting, especially in their front fog lamps (FFLs). As we all know, the FFL of a vehicle plays an important role in improving visibility under severe weather conditions such as fog, snow, rain or dust.…”
