Wat is lichtintensiteit

Definitie

Verlichtingsintensiteit is een fysieke term die verwijst naar de lichtstroom van zichtbaar licht die per oppervlakte-eenheid wordt ontvangen. Aangeduid als verlichtingssterkte, is de eenheid Lux ​​of lx. Het wordt gebruikt om de intensiteit van het licht en de hoeveelheid oppervlakte van het te verlichten object aan te geven.

In de fotometrie is “luminantie” de dichtheid van de lichtsterkte in een bepaalde richting, maar het wordt vaak verkeerd begrepen als verlichtingssterkte.… Read More

Design Considerations for Blue LED Incandescent Lamps

Introduction to Incandescent Lamps

Incandescent lamps have been used all over the world for more than 100 years since their invention. Incandescent lamps directly add AC mains power to the tungsten filament resistor to make it generate heat and emit light, thereby illuminating the dark. It enables hundreds of millions of people around the world to have the light and happy life brought by electric lights at night, as well as the convenience of work.… Read More

Comparação de luz HPS, MH e LED Grow Light

Comparação de consumo de energia LED VS HPS

O LED economiza mais energia, cerca de um quarto do consumo de energia da lâmpada HPS e da lâmpada de iodetos metálicos.

LED de 100w consome 0,1W de eletricidade, lâmpada HPS tradicional/lâmpada de iodetos metálicos 100W mais reator e transformador/gatilho consome 0,13-0,14w, o mesmo LED de potência economiza 30-40% de eletricidade.

Geralmente, lâmpadas LED de 25w-30w igual a lâmpada de sódio de alta pressão de 100W, lâmpada de LED de 40W igual a lâmpada de sódio de alta pressão de 150W, lâmpada de LED de 60W igual a lâmpada de sódio de alta pressão de 200W, lâmpada de LED de 80w-100w igual a lâmpada de sódio de alta pressão de 400W.… Read More

Proceso de empaquetado de LED

¿Cuáles son las causas de la temperatura de la unión LED?

  1. Regresa al interior del chip y finalmente es absorbido por el material del chip o el sustrato a través de múltiples reflejos internos y se convierte en calor en forma de vibración reticular, lo que hace que aumente la temperatura de la unión.
  2. La capacidad de disipación térmica del LED es otro factor clave para determinar la temperatura de unión.

Light Pollution and Sustainable Development of Night Lighting

Classification of Light Pollution

Human life is inseparable from light. Without light, the world would be pitch black. Like air and water, light is an essential element for human existence. We know that the human eye can adapt to a certain range of light radiation due to the adjustment of the pupil. However, when the light radiation exceeds the amount, it will have adverse effects on the living and production environment and human health, which is called light pollution.… Read More
