Glare, a common yet often overlooked aspect of lighting, refers to the discomfort or visual impairment caused by excessive and unregulated brightness from light sources. This occurs when intense light, whether directly from a source or reflected, enters the eyes, leading to a blinding or uncomfortable sensation. Glare can result in squinting, reduced visibility, eye strain, headaches, and other discomforts. This problem is particularly troublesome when lighting conditions are inadequately ...

It's time to shed some light on the age-old debate of lenses versus reflectors. Picture this as a friendly duel between two enchanting optical warriors, each with its own set of strengths and quirks. When it comes to lighting technology, LED chips emit light in a 180° dispersion, which is often too broad for practical use. To control and harness this light effectively, a secondary optical component is required. The two primary choices are reflectors and lenses, each with its own distinct ...

Introduction to Lighting Theory Lighting is an essential aspect of any space, and understanding the different types of illumination is crucial for effective light planning. In the 1950s, Richard Kelly, a renowned light planner, defined a basic classification of illumination types that remains relevant today. These types include: General Illumination - Light to See Functional Lighting - Light to Look At Accent Lighting - Light to Behold Each type serves a specific purpose in creating a ...

The Importance of Day Light in Sustainable Lighting Design   Daylighting, or the use of natural light to illuminate interior spaces, is an essential component of sustainable lighting design. Daylighting not only reduces the need for electric lighting during daylight hours, but also provides a host of additional benefits such as improving occupant comfort, enhancing the visual quality of spaces, and promoting overall well-being. In sustainable lighting design, daylighting is often the ...

When it comes to lighting, two important factors to consider are the Colour Rendering Index (CRI) and Colour Temperature. CRI measures the accuracy of how colours appear under a specific light source, while Colour Temperature refers to the perceived warmth or coolness of light, measured in Kelvins (K). Both CRI and Colour Temperature play a significant role in both interior and exterior lighting and can have an impact on each other. CRIThe Importance of Accurate Colour Rendering CRI is a ...

It's important to understand IP and IK ratings, as they play a critical role in determining the suitability of luminaires for various environments. These ratings are used to assess the protection levels of luminaires against various environmental factors, such as moisture, dust, and impact. In this article, we'll take a closer look at what IP and IK ratings are, and how they are used to evaluate the performance and durability of luminaires. IP RATINGS IP, which stands for "Ingress ...

Discover the definitions of key lighting terms to enhance your understanding of the art and science of lighting.AbsorptionAbsorption is the process of a material taking in light energy and converting it into another form of energy, such as heat. It is a key concept in lighting, as it is the process by which light is blocked or reduced. Absorption can be used to control the amount of light entering a space, as well as to reduce glare and improve the quality of light.BacklightingBacklighting ...
