Electrical and Electronics: Module 12

Module 12A: Residential Lighting (Core)

Suggested time: 15 - 25 hours

Level: Advanced

Prerequisite: Module 8

Foundational Objectives

To be knowledgeable and skilled with different materials and devices and their application in the electricity and electronics field.
To work safely and cooperatively with other students and handle materials in a safe manner.
To design and/or build circuits to an acceptable standard capable of producing a desired output.
To use and interpret meter readings.

Common Essential Learnings Foundational Objectives

To understand and install the different types of lighting circuits used in residential services. (TL)
To assess the efficiency of various light sources. (PSVS, CCT)

Learning Objectives	Notes
RESIDENTIAL LIGHTING SOURCES
12.1 To list the various methods of producing light.	Have students examine various types of lights (incandescent, fluorescent, high intensity). Examine the different types of bulb configurations.
12.2 To list the major parts of an incandescent light bulb.	Review the operation and operating principles of an incandescent light bulb.
12.3 To relate lamp life to line voltage for an incandescent bulb. (CCT)	Wire up a lighting circuit and observe what happens when voltage is decreased and increased.
12.4 To describe special purpose incandescent lamps. (COM)	Examine tri-lights, long-life, infrared, flood, halogenand rough service lamps.
12.5 To install a light fixture. (TL)	Install and connect different types of light fixtures.
12.5 To explain how a fluorescent lamp produces light. (COM)	Students should review the basic operating principles of the fluorescent tube and different types of fixtures.
12.7 To list the parts of a fluorescent lamp. (COM)	Disassemble a fluorescent lamp and examine the parts. List and explain the function of each part. Caution: Old fluorescent light fixtures may have ballasts that contain PCBs. They can be very hazardous if handled incorrectly. Observe proper precautions.

Module 12B: Residential Lighting (Core)

Suggested time: 5 - 10 hours

Level: Advanced

Prerequisite: Module 12A

Learning Objectives	Notes
SPECIAL LIGHTING SOURCES
12.8 To understand the production of light in a high intensity discharge lamp.	Explore the basic operating principles of a high intensity discharge lamp. Have students disassemble a high intensity discharge lamp.
12.9 To explain the light efficiencies of the different types of lights. (COM)	Compare the different types of lights and generate a list of efficiencies for each.
12.10 To wire a photoelectric cell.	Have the students wire a photoelectric cell to a lighting circuit to operate a lamp.
12.11 To describe the different characteristics of light and methods of measuring intensity. (NUM)	Students can discover a variety of methods to measure light. Show students how to determine the optimum light for a given application, then provide a variety of situations where students calculate the correct light intensity levels.
