Lighting Calculation

Coefficient Method and Point-by-point Calculation Method

Definition

Lighting calculation is an important part of lighting design. Illuminance calculation is also an important part of lighting function effect calculation. The purpose of illuminance calculation is to determine the power of the lamps and the number of lamps according to the required illuminance value and other known conditions (such as the type and arrangement of luminaires, the reflection conditions and pollution conditions of each surface of the room, etc.).… Read More

Caratteristiche dell’alimentatore per luci a LED

Le funzioni dell’alimentatore LED

Con il continuo sviluppo della tecnologia di confezionamento delle lampade a LED e della tecnologia di dissipazione del calore negli ultimi anni, la stabilità delle lampade a LED ha raggiunto un livello relativamente buono. Il decadimento della luce e la deriva del colore sono causati principalmente da prodotti di produttori scadenti, principalmente a causa di un design irragionevole di dissipazione del calore.… Read More

Common Household Light Source Types and Their Characteristics and Functions

Incandescent Light

Incandescent lamps, also known as tungsten filament lamps and light bulbs, are electric light sources that heat the filament to an incandescent state, and use thermal radiation to emit visible light.

Incandescent lamps only emit light from the thin filament, which is bright and dazzling and can easily cause glare. Some bulbs will soften the glass bulb of the cover to soften the light of the light source, but this also reduces the luminous efficiency of the light source.… Read More

Die Wirkung der Lichtintensität auf das Pflanzenwachstum

Die Bedeutung der Lichtintensität

Das Wachstum von Pflanzen wird durch die Speicherung von organischem Material durch Photosynthese realisiert, daher hat die Lichtintensität einen großen Einfluss auf das Wachstum und die Entwicklung von Pflanzen, was sich direkt auf die Stärke der Photosynthese auswirkt. Es gibt keine feste Proportionsbeziehung zwischen Lichtintensität und pflanzlicher Photosynthese, aber in einem bestimmten Bereich der Lichtintensität, wenn andere Bedingungen erfüllt sind, nimmt mit zunehmender Lichtintensität die Intensität der Photosynthese entsprechend zu.… Read More

Complementary Application Technology of Electrodeless Light and LED

Brief Introduction

With global warming, the development of low-carbon economy has become an international consensus, and it is also a new economic growth model for developed countries in the future.

A low-carbon economy is therefore expected to be high. It is not only an environmental protection means for the traditional industrial economy, but also is expected to become a new driving force for the global economy to get out of the “financial tsunami”.… Read More

Quelle est la différence entre SMD et SMT

Méthode d’inspection CMS

Méthodologie d’inspection : cet article explique que la surveillance des processus peut prévenir les défauts des circuits imprimés et améliorer la qualité globale.

La vérification peut souvent vous rappeler s’il y a trop de variables dans votre processus d’assemblage. Même après que votre processus de fabrication ait atteint une production continue sans défaut, une certaine forme d’inspection ou de surveillance est nécessaire pour garantir le niveau de qualité souhaité.… Read More

Classification and Selection of Lights and Fixtures

1. Protection Against Electric Shock

According to the classification of anti-shock protection methods, lamps can be divided into:

Class 0 lamps:

Lamps that rely only on basic insulation to prevent electric shock protection can only rely on the environment to provide reliable protection if the basic insulation fails.

Class I lamps:

Not only does it rely on basic insulation to prevent electric shock, but additional safety measures (grounding) are added.… Read More

Film nyomtatott áramkör

Az ilyen filmáramkört általában ezüstpasztával nyomtatják PET-re. Két eljárási módszer létezik az elektronikus alkatrészek beillesztésére és beillesztésére az ilyen típusú filmáramkörre. Az egyik a hagyományos eljárás, amely a 3 ragasztós módszer (piros gumi, ezüst gumi, kapszulázó gumi) vagy a 2 ragasztós módszer (ezüstgumi, kapszulázó ragasztó), egy másik úgynevezett új eljárás az 1 ragasztós módszer. —ahogy a neve is sugallja, 3 vagy 2 ragasztó helyett egy ragasztóval lehet elektronikus alkatrészeket beilleszteni és beilleszteni.… Read More

Lighting Design and Energy Saving Tips

1. Scientific Selection of Electric Light Source

Scientific selection of electric light source is the primary issue of lighting energy saving. At present, the luminous efficiency, lifespan, and color rendering performance of electric light sources are constantly improving, and energy-saving electric light sources are constantly emerging.

The light-emitting principle of electric light source can be divided into two categories. One is thermal radiation electric light sources, such as incandescent lamps, tungsten halogen lamps, etc.… Read More
