An in-depth knowledge of lighting calculations, such as the calculation of illuminance levels, lighting power density, and the use of photometric data to determine the distribution of light in a space.
Illuminance: The measurement of the intensity of light on a surface, measured in lux or foot-candles.
Lumen output: The total amount of light emitted by a light source, measured in lumens.
Color temperature: The measurement of the perceived color of light, measured in Kelvin (K).
Color rendering index (CRI): The measurement of how accurately a light source renders colors, rated on a scale from 0 to 100.
Light distribution: The way that light is dispersed from a light source over a given area.
Types of light sources: Including incandescent, fluorescent, LED, and other sources.
Lighting fixtures: Including task lighting, ambient lighting, accent lighting, and other types of fixtures.
Lighting controls: Including on/off switches, dimmer switches, and other types of controls.
Energy efficiency: Including the use of energy-efficient fixtures and controls to reduce energy consumption and costs.
Daylighting: The use of natural light to supplement or replace artificial lighting.
Glare reduction: Strategies for reducing glare from lighting sources to improve visibility and comfort.
Light pollution: The negative effects of artificial light on the environment and on people's health.
Accessibility: The design of lighting systems to accommodate people with disabilities or special needs.
Sustainability: The design of lighting systems to reduce waste, conserve resources, and promote environmental sustainability.
Lighting design software: Tools and software used to simulate and analyze the design of lighting systems.
Lux Calculation: Lux is the SI unit of luminance used to measure the amount of light that falls on a surface. Lux calculation is used to determine the required number of luminaires needed in a space.
Lumen Calculation: Lumens are a unit of measurement for the total amount of light emitted from a source. Lumen calculation is used to calculate the total amount of light that is needed in a space.
Room Cavity Ratio (RCR) Calculation: The RCR calculation takes into consideration the dimensions of the room, the types of surfaces, and the placement of the luminaires to achieve optimal lighting conditions.
Uniformity Ratio (UR) Calculation: Uniformity ratio calculates the distribution of light throughout the space. This ratio measures the difference between the minimum and maximum levels of illumination in a given area.
Depreciation Calculation: Depreciation calculation takes into account the wear and tear of the lighting fixtures over time. This calculation can help in determining when the fixtures need to be replaced or when maintenance needs to be carried out.
Daylighting Calculation: Daylighting calculation uses natural light to supplement artificial light in a space. This calculation involves the use of daylight sensors and automated controls to maintain optimal lighting conditions.
Kelvin Temperature Calculation: Kelvin temperature calculation is used to determine the color temperature of light needed in a space. This calculation ensures that the lighting fixtures produce the desired color temperature for the intended purpose.
Foot-Candle Calculation: Foot-candle calculation determines the amount of light that falls on a surface per square foot. This calculation helps in determining the required number of luminaires needed in a space.
Controllability Calculation: Controllability calculation involves the use of dimming controls and lighting sensors to optimize the use of energy and reduce energy consumption.
Flicker Calculation: Flicker calculation measures the rapid and repeated changes in illumination of a light source. High flicker can cause discomfort and headaches to people working or living in the space.
