Transcript of Design and development of Plasma Lighting System

Background
Introduction
Green De Corp. Limited
Company Based Project

Green and innovation

Design and development Stage

Plasma Lamp 1
Other Constraints
Design and Development
of Plasma Lighting System

Science Park :
Capacity of < 7.5meter lamp pole systems

Objectives
1. To study the characteristic and effects of plasma light

2. To develop the system to improve the efficiency of light source

3. To fabricate a prototype of plasma lighting system


Science Park
Provide a testing area for this project

Outline of Presentation
Presented by Chan Chi Yeung
Detail Design of
Fixture for Optics

Generate by RF energy
The Step generating light
1) The bulb contains
metal-halide
2) The electric field
ionizes the gases
inside the bulb
3) The
ionized gas in turn heats up
and evaporates the metal- halide materials

Metal-halide
Gases
ionizes
heats up

Plasma
Selection of
Plasma Lamp
Topangatech
- 90 or 180 degree
(Working Direction : Up or Down )
LUXIM
- 0~-90 degree
(Working Range : Horizontal to Down)
Innovative design: Place the light source on the lower position
Easy Maintenance
Private facility : Landscape*
* General Landscape lower than 7.5 meters
Design of Optics
Conceptual Design
Conceptual of
optical design
The 1st design of the whole project

Condensation and Parallel for the plasma light ray

Improve the efficiency for the lumux and light range
Design Consideration1
(Transmission part - Middle)
Thin film
Design Consideration2
(Source part - Near Light Source)
Fabrication of
Prototyping

Literature Review
Methodology
Resource: The Landscape Lighting Book, Janet Lennox Moyer, I.E.S., A.S.I.D, 1992
Development on Metal Halide
in Landscape purpose
Now,
plasma lighting will increase the product life
Resource:
Luminaire Optics and Photometrics, Lighting Design and Engineering Centre, Philips Lighting B.V. 1984
Selection of the Curved Reflector
The common curve for the reflector
Circle
Parabola
Ellipse
Hyperbola
Reflector Design
If not at the focus, but in front or behind it, the reflected rays will no longer be parallel
Resource:
Luminaire Optics and Photometrics, Lighting Design and Engineering Centre, Philips Lighting B.V. 1984
Circular
Parabolic
Elliptcial
Hyperbolic
4 curves adding light source
Reflector
Light ray transmits in parallel direction
Adviod unnecessary reflection
Parabolic curve is choosen
Software
LightTools
Simulate the light rays distribution
SolidWorks
Produce the engineering drawing
Ultra-precision
Single-point Diamond Turning
Produce the excellent surface
Machining
Coordinate Measuring Machine
Measure the curve of reflector
Reasonable for the prototype
Parabolic in curve
( parallel translate the light rays)
Single-point Diamond Turning is needed for prototype ( Solid-Aluminium)
Heatsink
(thermal conduction for light source )
Design Consideration3
(Last part - Reflect the light to the ground)
Elliptical design is needed
Requirenment:
8x20 meters recieved area
Pole Base
Install the parabolic reflector
Top Fixture
Fixture for the
Top reflector
Material Selection
Optics
Thin metal film
Reflector
Al with Sliver Coating
Aluminium*
-> Physical protection (Waterproof, etc..)
-> Private area (plagiarism for the design)
