Klíčové body designu kancelářského osvětlení

Koncepce designu osvětlení

Pro běžného administrativního pracovníka stráví v kanceláři každý den více než jednu třetinu svého času. Proto je kancelářské prostředí společnosti velmi důležité pro každého jednotlivého zaměstnance. Pro kancelářskou výzdobu je význam světelného designu ještě kritičtější. Kancelář slouží k práci a účelem práce je vytvářet bohatství. Proto racionalita návrhu kancelářského osvětlení ovlivní nadšení, efektivitu a dokonce i bezpečnost zaměstnanců.… Read More

Comprehensive Comparative Performance of HPS lights and LED lights

the Lifespan of Fixtures

Lamp life refers to the time from the start of use to the death of the lamp. For the lifespan of LED lamps, major manufacturers are now increasing the lifespan of the light source over how many hours, and calculating the uniformity of illumination.

Take the point directly below a light source, make a vertical line, and pass two points AB on both sides of the traffic lane.… Read More

Verlichtingsvereisten van fabrieken, havens en benzinestations

Korte introductie

Wat voor soort lampen er op gewone werkplekken moeten worden gebruikt, wordt ook bepaald door de omgeving waarin ze worden gebruikt. Neem als voorbeeld fabrieksverlichting. Als de luchtvochtigheid in de werkplaats hoog is, is het noodzakelijk om lampen te gebruiken met goede waterdichte prestaties, terwijl in stoffige werkplaatsen stofdichte lampen moeten worden gebruikt. In deze gevallen moet de IP-classificatie van de gebruikte lampen zorgvuldig worden gekozen.… Read More

Some Knowledge about LED Efficiency

LED Efficiency Overview

Due to their various advantages, LEDs have become an important part of semiconductor light sources for general lighting applications. For some time, LED efficiency has been significantly higher than conventional lighting technologies. But how to define the efficiency of a solid state lighting (SSL) system? In common everyday language, when we talk about the efficiency of light sources, we usually refer to their luminous efficiency, measured in lumens per watt (lm/W).… Read More

O princípio do dimmer e o método de escurecimento de várias luzes

O dimmer é um dispositivo elétrico, que fornece função de escurecimento ininterrupto de acordo com os requisitos do usuário. Existem muitos tipos de lâmpadas elétricas no mercado, mas nenhum dimmer pode ajustar todos os tipos de lâmpadas elétricas.

 

Existem muitos tipos de luzes elétricas:

A lâmpada incandescente tradicional inventada por Thomas Edison,

Lâmpada halógena de alta tensão, usando corrente alternada de 230V,

Lâmpada halógena de baixa tensão, usando fonte de alimentação de 24V, existem duas maneiras de reduzir 230V para 24V: (a) usar um transformador simples ou (b) usar uma fonte de alimentação de comutação eletrônica,

Lâmpada fluorescente/lâmpada fluorescente e tubo de economia de energia (CFL, lâmpada fluorescente compacta) é um tipo especial de lâmpada fluorescente.… Read More

Способы улучшения коэффициента мощности светодиодных ламп

Что такое коэффициент мощности

Будь то светодиод, люминесцентная лампа или лампа накаливания, мы все должны понимать, что коэффициент мощности (PF) является одним из ее важных параметров. Давайте поговорим о том, что такое коэффициент мощности.

Коэффициент мощности представляет собой способность лампы выдавать активную мощность. Мощность является мерой скорости передачи энергии. В цепи постоянного тока это произведение напряжения V и тока а. В системе переменного тока это сложнее: то есть некоторая петля переменного тока в нагрузке не передает мощность, которая называется током реактивного сопротивления или гармоническим током, что делает полную мощность (напряжение вольт, умноженное на ток в амперах) больше, чем фактическая сила.… Read More

Bio-Optics Basics

The Concept of Light

Light is an electromagnetic wave that has the duality of waves and particles. Like all other waves, light waves have wavelengths, denoted by λ. The most commonly used unit for light waves is the nanometer (nm). A spectrum is obtained by arranging the wavelengths of light waves in order from shortest to longest. In the spectrum, γ-rays, x-rays, ultraviolet rays, visible light, infrared rays, radio waves, etc.… Read More
