Le caratteristiche dei fenomeni visivi del tunnel

Durante il giorno, l’autista entra nel tunnel fino all’uscita dal tunnel e incontrerà molti problemi visivi.

Problemi visivi prima di entrare nel tunnel: in un lungo tunnel, il conducente vede un buco scuro. Questo è il fenomeno del “buco nero”. In un breve tunnel, davanti al guidatore appare una “cornice nera”.

Alta luminosità esterna, bassa luminosità in ingresso, luce diffusa nell’aria, che influisce sulla luminosità del parabrezza: un fenomeno visivo che può verificarsi quando si entra nel tunnel, dall’esterno luminoso in un tunnel più buio, perché la visione del conducente ha bisogno di un certo tempo di adattamento (Adattamento oscuro della visione), quindi non può vedere rapidamente la situazione all’interno del tunnel.… Read More

Advantages of LED Lights

Advantage 1. The lamp body is very small

LED lamp is a very small, very fine LED chip encapsulated in transparent epoxy resin, so it is very small, very light, it can save a lot of materials and space in production and application.

 

Advantage 2 very low energy consumption

The working voltage of the LED lamp is generally only 2~3.6V, and the working current is only 0.02~0.03A.… Read More

Vergleich des Lichtprinzips von LED-Lampen und Natrium-Hochdrucklampen

LED-Licht emittierendes Prinzip

LED (Light Emitting Diode), eine lichtemittierende Diode, besteht aus Verbindungen der III-IV-Gruppe. Es ist ein Festkörper-Halbleiterbauelement, das Elektrizität direkt in Licht umwandeln kann. Das Herz der LED ist ein Halbleiterchip. Der Halbleiterchip besteht aus drei Teilen, einem Teil ist ein Halbleiter vom P-Typ, in dem Löcher dominieren, und das andere Ende ist ein Halbleiter vom N-Typ.… Read More

Working Principle of Metal Halide Lamp Ballast

Metal halide lamp ballast

The metal halide lamp in the electronic ballast 35W metal halide bulb arc has negative resistance characteristics in all gas discharge lamps; that is, as long as the current through the bulb increases, the voltage across the voltage decreases. If the bulb is powered from a constant voltage source, such as directly from the AC wiring, the current will increase until the bulb destroys itself; therefore, the halide bulb requires an electric ballast to limit the current of the arc.… Read More

Three Common Faults and Solutions of LED Lights

LED lamps are energy-saving, high-brightness, long-life, and low-failure rate. They have become the favorite luminous body of ordinary household users. However, a low failure rate does not mean that there is no failure. What should we do when the LED lamp fails-replace the lamp? Too extravagant! In fact, the cost of repairing LED lights is very low, the technical difficulty is not high, and ordinary people can operate it.… Read More

Jalkapallokentän valaistuksen kustannukset

Ennen kuin tiedät kuinka paljon rahaa tarvitaan jalkapallokentän valaisemiseen, sinun on tiedettävä jalkapallokentän koko ja jalkapallokentän urheilutaso, jotta voit karkeasti tietää, kuinka monta tehoa valoa tarvitset. Kun tiedät tehon, tiedät valojen kustannukset ja jopa niihin liittyvän sähkölaskun.

 

Stadionia rakennettaessa tärkein asia, jonka omistajan on ymmärrettävä ennen kalusteiden ostamista, on stadionin valaistuskustannukset. LED-urheiluvalaisinmerkin ja -lähteen mukaan tuotteiden hintoja ei voida yhtenäistää.… Read More
