Design and Application of Light-guide Lighting System

Principle and Composition of Light Guide Lighting System

Light guide lighting is also called pipe-type daylight lighting. The system efficiently collects natural light through the daylighting hood and introduces it into the system for redistribution. After being transmitted and strengthened by a specially made light pipe, the diffuser at the bottom of the system irradiates the natural light evenly and efficiently to any place where light is needed to obtain the special lighting effect brought by the natural light.… Read More

Classification and Layout of Stadium Lighting

Calculation of Stadium Lighting Design

Calculation method of average illuminance:

Use the following formula to calculate the number of lamps.

N=E×A/η×F×K

In the above formula: N—the number of lamps, E—the average surface illuminance lx, which can be found from the table: A—the illuminated area m2, η—the efficiency of the lamps, F—luminous flux 1m, K—maintenance coefficient, taking 0.7～0.8 . The above two illuminance calculation methods are widely used, mainly used for illuminance estimation, and are more suitable for the plan and preliminary design stage.… Read More

Comment régler la température de couleur des lumières LED

 Le principe de la luminosité de réglage de la température de couleur LED

La température de couleur des LED consiste à modifier le rapport des différentes lumières. L’augmentation de la lumière rouge rend la température de couleur plus chaude et l’augmentation de la lumière bleue rend la température de couleur plus froide. Ajustez la luminosité, modifiez le courant traversant la LED, plus le courant est grand, plus il est lumineux.… Read More

Analyse af seks almindelige problemer med hvid LED

Hvorfor kan vi ikke bruge hvide lysdioder til overspænding eller overstrøm?

Generelt er den mest almindeligt anvendte 5 mm x 5 mm hvide lys LED, dens normale arbejdsspænding er for det meste i området 3,0-3,5V, og den normale arbejdsstrøm er 20mA. Men mange mennesker tror fejlagtigt, at brug af hvide LED’er til overspænding eller overstrøm vil være lysere.

Det faktiske testresultat er, at lysstrømmen stiger meget kraftigt efter 15mA.… Read More

Lighting Standards for Different Places

(1) Emergency lighting

According to 10.1.5 of IEC50016-2014, there are three continuous working hours of emergency lighting backup power supply: 0.5, 1.0, and 1.5h. 0.5h can be used conventionally to meet the IEC17945 self-provided battery (manufacturing standard is not less than 90min) to solve. How to achieve the 1.0 and 1.5h requirements is more reasonable and feasible.… Read More

10 katuvalosuunnittelun pääkohtaa

10 Points of Street Light Design

  1. Onko katuvalon pääkytkin 3P vai 4P?

Jos kyseessä on ulkovalaisin, vuotovaaran välttämiseksi asennetaan vuotokytkin ja 4P-kytkintä tulee käyttää tässä vaiheessa. Jos vuotoa ei oteta huomioon, pääkytkin voi olla 3P-kytkin.

 

  1. Erilaisten katuvalaisimien edut ja haitat

Yksipuolinen asettelu-sopii suhteellisen kapeille teille, hän edellyttää, että valaisimien asennuskorkeus on yhtä suuri tai suurempi kuin tien tehollinen leveys. Sen etuna on hyvä kannustin ja alhaiset kustannukset.… Read More
