A particular kind of electromagnetic energy called light gives objects visible to the human eye. Visible radiation to the human eye is another definition of it. Light is made up of photons, which are small energy packets. Light source Why does the grass, leaves and plants is green? It is because there is a light that bounce of the plants to our eyes that is why we see a color. Everything that we observe in our surroundings is a result of light. Human eyes are sensitive to between 390 to 700 NM, which is a specific frequency of electromagnetic radiation, also known as light. Even when we focus on a single leaf, we are already aware of its green color since light reflects off of it and reaches our eyes, indicating its color. Like all other forms of energy, light is any form of energy that originates from a source. We refer to these sources as light sources, according to www.vedantu.com (2024) Types of light source 1.Naturat Light Numerous objects in our cosmos have their own light sources. A portion of the light emitted by these sources can be seen on Earth's surface. The following list includes objects that can emit light that are found in nature. Sun Light One of the main sources of light for the planet Earth is the Sun. The Sun is thought to be a huge ball of fire that fusions nuclear matter at its core to produce enormous amounts of energy. Heat and light are the products of this solar energy. The light from the Sun is the main element responsible for the sustenance of life on Earth. Moon Though it doesn't create light on its own, the moon also gives light. The light that the moon gives us comes from the light that the moon reflects off of the sun.

Organism / Bioluminescence Certain live things are also capable of producing their own light. We refer to them as bioluminescence. These include, for instance, glow worms, fireflies, and jellyfish. 2.Artificial Light Aside from natural sources, artificial light production is also possible. Three categories can be used to group the various artificially created lights. These consist of gas discharge sources, luminescent sources, and incandescent sources. Incandescent Light The most common example of incandescent light is fire, which results from a chemical process that generates heat and gasses, raising the temperature of the substance to a point where the gas and material become incandescent (lighten up). Luminescent Sources Electric bulbs and fluorescent tube lights are two instances of it. These sources are different from incandescent light sources in that they just use electrons rather than complete material vibrations, and they operate at normal or lower temperatures. Discharge Sources Under gas discharge sources, light is produced by passing electricity through a specific gas at very low pressure. Neon and sodium lamps are two examples of it. Lighting Design Republic of the Philippines Don Honorio Ventura State University - Candaba Campus Pasig, Candaba Pampanga, 2013 DCC@dhvsu.edu.ph _____________________________________________________________________________________ Lighting design calls for sensitivity to architectural and aesthetic concerns in addition to a technical grasp of electrical, light sources, and vision. The final design must illuminate the surrounding surroundings and architectural forms while also satisfying the visual needs of human eyes executing an infinite variety of functions. Different lighting design that is being used in Architectural design and Construction 1.Cove Lighting Cove lighting, which is mounted on a wall or ceiling, highlights specific architectural elements with a gentle glow. The LED light is tucked away inside a built-in cove and is intended to wash a wall or ceiling. It works best as ambient accent lighting, and it usually has an indirect light source. The final design is sleek, contemporary, and perfect for a wide range of business uses. 2.Uplighting It describes any light fixture that focuses light upward, reducing glare and emphasizing any unique ceiling architecture while also adding to the room's mood and spatial aspect. The technology lessens shadows and dark areas in ceilings, especially in interior applications, to create userfriendly and cozy environments. 3.Linear Recessed With seamless transitions from ceiling to wall, linear recessed lights provide continuous, aesthetically pleasing runs of high-CRI LED illumination in any desired length. These are frequently seen in offices that seek to create a dynamic environment that fosters creativity, productivity, and alertness. Architectural lighting systems are often available in four- and eight-foot standard lengths (or other custom lengths) and can be recessed into the ceiling, wall, or floor to create any desired linear design. 4.Surface and SuspendedSurface and suspended lighting is versatile and can adapt to a wide range of applications.

However, the previous lighting used which is incandescent lamp consumed a lot of energy, that is why it will replace by the new LED track luminaires. Based on an operation of approximately 2,340 hours a year, the analysis indicated an energy saving of 37,674 kWh annually. Considering the impact on the mechanical cooling and heating systems the total expenditure savings, on energy consumption alone, is predicted at $7,997.65 per annum. The projected expenditure savings for lamp replacement moving from incandescent to LED is predicted at $4,922.06 per annum. Replacing incandescent lamp to LED lighting will not only minimize the energy consumption, but to make a comfort to the people inside the gallery. Key Point Replacing Incandescent lamp to LED track fitting From high energy consumption to low LED track luminaires for greater energy efficiency, reducing energy consumption of the lighting load and a reduction in the heat load LED is more flexible that Incandescent lamp Legal principles in the study The previous installation of light in the gallery was studied properly before conducting a new upgraded solution such as replacing incandescent lamp to LED Reflection I learned that LEDs last longer than incandescent light because of the previous study in the the Lake Macquarie City Art Gallery. This case study gives me an idea on how on important the comfortness and location of lighting in the building. Also, when installing a lighting system, the energy consumption of light should be consider Aside of lighting, I learned how they make case study properly, it is similar to site visit and identifying solution to a building.
