Compact fluorescent lamps and high frequency fluorescent lamps are types of fluorescent lamps that use cold cathode technology. Fluorescent lamps come in different varieties including compact fluorescent lamps that are smaller than traditional fluorescent tubes and high frequency fluorescent lamps that use a higher frequency ballast to start the lamp.
Introduction For Lighting Luminaries
The document discusses lighting systems and designs for a factory. It identifies problems with the current lighting system such as not meeting lux level recommendations and not using efficient luminary and lamp types. To address this, the author proposes redesigning the lighting system using the Dialux program to select more appropriate luminaries and lamps that satisfy lighting codes and provide efficient energy use. The document then provides definitions and classifications related to lighting design standards and components.
Energy lighting 01
The document discusses lighting design for commercial buildings. It covers several key points:
1. Lighting accounts for 20-40% of total energy consumption in commercial buildings. Proper lighting design offers opportunities for energy efficiency.
2. Different tasks require different types and amounts of light. The quality of light is as important as the quantity. Energy efficiency can be achieved by providing the right quality and quantity of light.
3. A lighting design considers several factors like lamp selection, luminaire selection, integration with daylight, controls, code compliance and more. Proper lighting design involving a lighting designer can optimize energy efficiency and lighting needs.
Illumination.
This document discusses illumination and lighting design. It begins by outlining the objectives of studying illumination for architects, including providing proper ambient lighting, safety, and energy efficiency. It then defines key lighting terms like illuminance, luminous intensity, and luminance. The document covers the inverse square law and Lambert's cosine law governing light distribution. It describes the history of lighting technologies from candles to modern LEDs. It also discusses light sources like fluorescent lamps and the types of lighting schemes and lamps used in various applications.
Choosing Fluorescent Bulbs
This presentation provides a cursory overview of the different types of fluorescent bulbs available to the average consumer. There are images to help our readers visualize our words as well as a couple of charts detailing sizes, lumens, and why each is different.
ELECTRICAL LAMPS AND THEIR TYPES
Electrical lamps have several advantages over mechanical lamps including cleanliness, easy control, lower cost, ease of use, steady output, reliability, and suitability for many purposes. Common electrical lighting types discussed in the document include incandescent, fluorescent, high intensity discharge, and light emitting diode lamps. Incandescent lamps work by passing current through a tungsten filament to produce light, while fluorescent lamps use mercury and phosphors to convert ultraviolet light into visible light. Tungsten-halogen lamps improve on incandescent efficiency through the use of halogen gases.
LED vs Fluorescent Lamps
T12 production ended July 2012. Your decision point is a migration to T8 and new ballasts or T5 and new fixtures - or LED. You know that your energy costs are going up by 40% in the next couple of years and likely 100% over the next 10. Why not use todays money to light your path to future profitability. The highest ROI is LED.
Types of Lamps
The document discusses different types of lamps, including incandescent, fluorescent, sodium, and high pressure mercury vapor lamps. Incandescent lamps produce light through a heated filament, but are inefficient with a short lifetime. Fluorescent lamps are more efficient and have a longer lifetime than incandescent, using a phosphor coating and electrodes to excite mercury vapor. Sodium lamps use sodium gas to produce light very efficiently with a long lifetime, while high pressure mercury vapor lamps contain argon and mercury gas.

Calculations of illumination
This document discusses methods for calculating illumination levels. It introduces the lumen method and point method. The lumen method calculates illuminance based on the total lumens of a light source and area of the surface. The point method calculates illuminance based on light intensity and distance. The zonal cavity method is introduced as an application of the lumen method for interior spaces. It includes coefficient of utilization and light loss factors to account for light lost from the source and room characteristics. Correction factors are needed because not all light reaches the surface and light output decreases over time.
Different types of lamps
This document discusses different types of lamps, including neon lamps, mercury vapor lamps, sodium vapor lamps, LED lamps, compact fluorescent lamps, incandescent lamps, halogen lamps, and fluorescent lamps. It provides details on the composition and operation of each type of lamp, noting attributes like energy efficiency, lifespan, color temperature, and applications. The document aims to educate readers on the various lighting technologies available.
Illumination - Types of lamps
The document discusses lamps and different types of lamps. It provides details on fluorescent lamps, including their components, construction, working, advantages, disadvantages, and applications. The key components of a fluorescent lamp are electrodes, gases like mercury vapor and argon, and phosphor coating. It emits light when mercury vapor is excited by electrons from the electrodes, causing the phosphor coating to fluoresce. Fluorescent lamps have higher efficiency and longer life than incandescent lamps.
LIGHT AND LIGHTING FIXTURES
The presentation discusses light and lighting fixtures. It defines light and how it is produced through electrons moving between orbits in atoms. It then covers the different types of light sources including natural light and various artificial lights. The rest of the presentation focuses on methods of lighting, including types of lighting fixtures for indoor and outdoor use. It also addresses the effects of lighting in different areas and the advantages and disadvantages of natural versus artificial light.
Illumination - Method of calculation
There are three main methods for lighting calculations: 1) Watts per square meter, 2) Lumen or light flux, and 3) Point to point or inverse square law. The lumen method is used to estimate illumination patterns from diffuse lighting sources over a broad area. It determines the total installed luminous flux (Φinst) needed to provide the required received flux (Φrec), taking into account the maintenance factor and utilization factor. The utilization factor depends on luminaire properties, room reflectance, distribution of light sources, and the room index. The number of lamps required is calculated as the product of the required flux and area divided by the lamp lumen output and adjustment factors.
Lighting ppt 1
This document discusses ways to reduce energy usage from lighting in buildings through green practices. It recommends using natural daylight whenever possible through proper window and skylight design. When artificial lights are needed, the right amount and type of lighting should be used based on the task. Different lighting technologies like LEDs and fluorescents are more efficient than incandescent bulbs. Automatic controls can further reduce energy by turning lights off when not needed or adjusting output based on daylight.
Lighting Powerpoint
Stage lighting has several functions including illumination, revelation of form, focus, mood, location/time of day, projection of stage elements, and advancing the plot. Various lighting instruments like fixtures, dimmers, and lighting consoles are used to control lighting properties like intensity, color, pattern, focus, and position to achieve different lighting styles such as high-key and low-key lighting.
Power transmission(ppt)
This document discusses the per unit system used in power transmission. It defines key parameters like voltages, currents and impedance. It introduces the per unit system and formulas for converting values to a per unit basis by dividing the actual value by a base value. Base values can be the rated voltage and power values. The per unit system simplifies circuits and allows values to remain the same regardless of the size of the system. It has advantages like simplified analysis and manufacturer specification of components in per unit values. Disadvantages include more abstract equivalent circuits.
