Deux applications d’éclairage commercial courantes pour les lumières LED

1. Introduction

De l’invention de la diode électroluminescente en 1907 au développement réussi de la LED bleue en 1995, l’éclairage à semi-conducteur a subi un processus tortueux. Cela inclut la “bataille de camp” entre le carbure de silicium (SiC) et le nitrure de gallium (GaN) dans le développement des LED bleues. Après la préparation technique pour le développement précoce de la LED, elle est maintenant entrée dans une période de croissance rapide.… Read More

A LED-fényforrás öt fő problémája

Az általános világításhoz az embereknek elsősorban napfényhez közeli fényforrásra van szükségük, így a fehér LED a világítástechnika fontos indikátorává vált. A fehér LED-ek és az általános világítási követelmények között azonban még mindig nagy a távolság, és még mindig sok a megoldásra váró probléma.

 

1. Alacsony fényáram és magas ár.

Például: egyetlen 1 W-os LED-es készülék fényárama körülbelül 25 lm. A jó minőség ára több mint 8 dollár, a gyengeé 4 dollár.… Read More

Der Unterschied zwischen dreifarbigen Energiesparlampen und gewöhnlichen Energiesparlampen

Was ist eine dreifarbige Röhre?

Die Drei-Primärfarben-Röhre bedeutet, dass das fluoreszierende Pulver in der Röhre als Leuchtstoff eine Kombination aus drei Arten von Leuchtstoffen ist, die rotes, grünes und gelbes Licht emittieren können, das weißes Licht emittiert, und das Licht, das es emittiert, ist dem ähnlich Farbe des Tageslichts; seine Herstellung Die Kosten sind höher als die von gewöhnlichen Leuchtstofflampen, und es ist visuell “komfortabler” als gewöhnliche Leuchtstofflampen.… Read More

Zes indicatoren voor de kwaliteit van de binnenverlichting

De lichtverdeling van de lamp is gerelateerd aan de lichtfunctie van de lamp. Railspots en plafondlampen gebruiken over het algemeen een lichtverdeling van 15° of 30°. Downlights gebruiken over het algemeen een lichtverdeling van 30 of 60 graden. Gloeilampen en plafondlampen hebben over het algemeen een lichtverdeling van 120 graden. De lichtverdeling van het lamppaneel ligt tussen de 60 en 90 graden.… Read More

LED Street Light Road Model and Lighting Simulation Analysis

Abstract

Aiming at the current road lighting problem of LED street lamps, this paper uses DIALUX software to model the road lighting scheme. Research and analyze whether the lighting effect of LED street lamp meets the international lighting standard CIE under the premise of fixed LED light source power and light distribution curve.

According to the analysis results of optical simulation modeling, the key factors affecting the lighting effect of LED street lamps are obtained: the installation method of the illuminator, the installation height of the LED pole, the installation distance of the LED pole, the light source power of the illuminator, and the light distribution curve of the illuminator .… Read More
