SPECIFICATION OF LEDS: LUMINAIRE HOUSING
IIEE-ERCSA
12 July 2019
 SMD (Surface Mounted Device) LED
~ LED chips are permanently mounted on PCB
~ Commonly seen in LED bulbs and strip LED lights
~ can have more than just two contacts
~ can be up to 3 diodes on a single chip, with each diode
having an individual circuit.
~ Each circuit would have one cathode and one anode,
leading to 2, 4 or 6 contacts in a chip.
~ The chip can include a red, green, and blue diode. With
these three diodes, you can already create virtually any
color simply by adjusting the output level.
~ SMD chips are also known to be bright. They can
produce 50 to 100 lumens per watt.
APPLICATION:
Best used for RGB Application
Best used for LED Panels and LED Linear
Versatile use of lens makes it ideal for Floodlights, Streetlights and Highbays

IIEE-ERCSA
12 July 2019
 COB (Chips on Board) LED
~ is a new technology of LED packaging
~ commonly seen in LED bulbs and strip LED lights
~ typically have 9 or more diodes and only have 1 circuit
and 2 contacts, regardless of the number of the diodes
~ has more diodes and gives off panel-like appearance
~ can’t be used to create colour changing bulbs or lights
but ideal for Mono-Color LED
~ Diffusers are needed to control glare
APPLICATION:
Best used for downlights and spotlights due to its concentrated light beam

IIEE-ERCSA
12 July 2019
 STAINLESS STEEL GRADE
The SAE steel grades system is a
standard alloy numbering system for
steel grades maintained by SAE
International.
APPLICATION:
~ Type 304 - (US) the most common
grade of steel. Stronger grade. Used for
almost all as raw materials for fixtures.
Also known as A2 stainless steel or
SUS304 (Japan)
~ Type 316 - for food and surgical
stainless steel applications uses as well
as Salt Water & Marine Application
~ Type 316L - same as above but for
low-carbon application. Also known as
A4 stainless steel

IIEE-ERCSA
12 July 2019
 ENCAPSULATED (POLYURETHANE) PU
LEDs are sensitive electronic components and often require
additional protection against mechanical damage, moisture,
and other environmental factors.
ADVANTAGES:
~ can be mono or RGB LED
~ gives off a hazy/cloudy light-diffusing effect
~ flexible/elastic/rubbery
~ high electrical insulation
~ low conductance to heat
~ underwater (LED driver must be above water and using
IP68 cable glands)
HIGH RESISTANCE AGAINST:
~ mechanical stress or shock
~ moisture & humidity ingress
~ exposure to chemical contamination
~ high-temperature environments: -25 to +50 C
~ fire-retardant
AL-SI11
PAVERLED

IIEE-ERCSA
12 July 2019
 ALUMINUM PROFILES FOR LED STRIPS
~ wraps to the PU encapsulated LED
~ keeps the Linear LED, linear!
~ prevents LED strip curving when adhesive is not holding anymore
AL-SI01

IIEE-ERCSA
12 July 2019
 LED OPTICS
LED lighting fixtures utilize at least one type of secondary optic to alter the beam of light
coming from the LED source. We look at 2 materials used:
REFLECTORS:
~ sit behind the LED to alter the beam
of light
~ made using plastic and can be metal
coated.
~ can be smooth or multifaceted
inside and in various different shapes
LENSES:
~ sit behind the LED to alter the beam
of light
~ come in various shapes and sizes,
for example round, square and
hexagonal
~ enable precise control over the
beams of light
~ masking the LED components within
DIFFUSERS:
~ come in various shapes and sizes, for
example round, square and hexagonal
~ enable precise control over the beams of
light
~ masking the LED components within
~ usually gives off increase of 10% light due
to diffusion (opalized diffuser)
~ usually gives off 120° beam

IIEE-ERCSA
12 July 2019
 DIFFUSERS
PMMA (OPALIZED)
~ Clear plastic, sometimes
known as acrylic
~ is a cost-effective material
which is common in lenses
~ gives off extra ±10% light
APPLICATION: general lighting,
yellowing after some time
PMMA (PRISMATIC):
~ made of clear plastic have a
transmission of 70–90%
~ difficultly of ensuring
homogenous light distribution and
precise glare control
APPLICATION: not recommended
due to uncontrolled light & glare,
yellowing after some time
PC (POLYCARBONATE)
~ Temperature and impact
resistant plastic
~ also offers great optical
characteristics
APPLICATION: best for
outdoor, industrial and harsh
environments

IIEE-ERCSA
12 July 2019
 GLASS
PROS:
~ Mechanical Strength and Durability (thermal, chemical, and
environmental)
~ Components Protection (does not carry a static charge that
attracts dirt)
~ UV Resistance (Glass does not degrade to the intense and
prolonged UV exposure)
~ Cost and Sourcing (low-cost and readily available material)
~ Flexibility (easily fabricated raw material)
CONS:
~ losses 9-10% of transmitted light by its material properties
alone
~ appears to be smooth, stable and chemically inert but
microscopically rough but chemically reactive
~ due to hydrophobic behavior, it causes dirt and debris build-up
~ Nearly 30% light loss seen in field due to dirt depreciation over
a luminaire’s lifetime
~ external and aging effects causes it be brittle and crack
eventually likewise but much worse with plastic diffusers

IIEE-ERCSA
12 July 2019
 GLASS
PROPERTIES GLASS COVER PC COVER
Scratch Resistance Good Bad
Light Transmittance less 10% plus 10%
Glare Direct Diffused
Breakage Resistance Weak Stronger
Weight Heavier Lighter
Dirt Maintenance Good Good
UV Resistance Good Bad
Protection Good Good
Not Yellowing Good Bad
BEST PRACTICE:
1) Insist on using Glass Covers on all Outdoor LED Luminaires
a) Applicable to most End-Users specification esp in dusty environments
b) Order Tempered Glass (tougher and also safer when glass breaks)
c) Order Flat Glass to prevent dirt and grime accumulation

CONSTANT CURRENT LED DRIVERS
are designed for a designated range of output
voltages and a fixed output current (mA). LEDs that
are rated to operate on a constant current driver
require a designated supply of current usually
specified in milliamps (mA) or amps (A). These
drivers vary the voltage along an electronic circuit
which allows current to remain constant throughout
the LED system.
Higher current ratings do make the LED brighter, but
if not regulated, the LED will draw more current than
it is rated for. Thermal Runaway refers to excess
current beyond the LEDs maximum drive current
which results in drastically lower LED life-spans and
premature burn outs due to increased temperature.
A constant current driver is the best way to drive
high power LEDs as it maintains a consistent
brightness across all LEDs in-series.

 CONSTANT CURRENT vs CONSTANT VOLTAGE
CONSTANT VOLTAGE LED DRIVERS
are designed for a single direct current (DC)
output voltage. Most common constant voltage
drivers (or Power Supplies) are 12VDC or 24VDC.
An LED light that is rated for constant voltage
usually specifies the amount of input voltage it
needs to operate correctly.
A constant voltage power supply receives standard
line voltage (120-277VAC). This is the type of
power that is typically output from your wall
outlets around the home. Constant Voltage Drivers
switch this alternating current voltage (VAC) to a
low direct current voltage (VDC). The driver will
always maintain a constant voltage no matter
what kind of current load is put on it.
BEST PRACTICE
~ Use Constant Current Drivers for High Powered LEDS to avoid LED burnout.
~ Use Constant Voltage Drivers for multiple LEDs arrays like LED rope light, LED strips,
LED bars, etc.

 INPUT VOLTAGE & FREQUENCY
At the moment, almost all application requires 220V – 60 Hz
However, there are older installations with existing systems of 110V – 60 Hz
In the market you are able to order the following drivers:
a) 100 - 277V, 50-60Hz (Universal), 200 - 240V (Direct)
b) 347 - 480V, 50-60Hz
c) DC drivers for 12V, 24V even 48V
 POWER FACTOR
~ Power Factor Correction is done on LED driver level.
~ No LED should have a Power Factor of less than 0.90.
 TOTAL HARMONIC DISTORTION (THD)
~ Power Factor Correction is done on LED driver level.
~ No LED should have a Power Factor of less than 0.9.
TOTAL HARMONIC

 0-10V vs 1-10V LED DIMMERS
1-10V Dimming Driver
~ uses Pulse-width modulation and 100 ohm resistor
~ a 100% light output of LED is given 10V while minimum
is 10% light output at 1V
~ An actual switch off is required to completely turn off
the LED
0-10V Dimming Driver
~ Newer generation with the same principle
~ The difference is that its minimum is at 5.7% or 0.57V.
~ Anything lower than 0.57V is completely turned off
APPLICATION:
~ Since these are older generation dimmers, you order
the dimmer of your LED that matches as-built
dimming system
~ Best to order 0-10V dimmers
