Pretoria LED Interior
Lighting System Overview
LED Interior Lighting Systems
with Functionality and Aesthetic
Options for all
Buses and Budgets
Pretoria began Supplying Interior LED Lighting Systems in
2007 for Service in North American Transit Buses. Our Newly
Developed LED System Offers Seamless Light with a Variety of
Options to Assist in the
Reduction of Windshield Glare
Our Unique LED Systems are Designed to Enhance the
Interior of the Bus, to Create an Inviting Interior and are
Engineered to Last the Life of the Bus, While also
Eliminating:
-
High Output Voltage Ballast
Fluorescent Lamp Tubes - EPA Disposal Issues
Frequent Maintenance Associated with Some Fluorescent Systems
Blank or Dead Spaces Between Fixtures, Offers Full Length Lighting
Color Inconsistencies – Bright Spots and Uneven Light Output
Bus Driver Windshield Glare
May pose a safety concern during night time rural routes.
Many factors such as the interior color scheme of the bus, the bus
drivers driving position, external/internal light conditions and the
shape of the windshield have effects windshield glare.
The Pretoria LED System offers
three Functionality or Operating options
to aid in the reduction of windshield glare and improve safety.
Standard Configuration
Duplicates the dimming and extinguishing functionality of
fluorescent systems plus the below no-charge options
- LED Driver allows for Dim Mode of 10%, 20%, 40%, 60% or 80% light output with 24V input
- LED Driver allows for Extinguish Mode via opening/closing of power circuit
- Two LED color options:
Nominal 6500K (Cool White)
Nominal 4500K (Warm White)
- Internal embossed prism PC lens that evenly fills the lens and distributes the light.
- Lens options available are White, White/Blue - Custom Colors are available
- Fixture to fixtures seamless light, the fixtures translucent end caps seal the fixture ends.
- SBPG compliant light levels. Note: The use of glare reduction features such as the
extinguishing or dimming of light fixtures, the use of tinted lens or colored
LED’s may result in reduced light output.
- 12 – Year System Warranty
Manual Dimming Option
(variable light level range, upgrade system)
As individual bus drivers have varying glare issues due to body height and
driving positions, the Manual Dimming Configuration is unequaled in
windshield reflection reduction. The bus driver / property can easily adjust the
R/S, C/S or specified fixtures light levels output to best suite their individual needs.
- Driver console or concealed cabinet mounted R/S and C/S potentiometers for variable
light intensity with an output ranging from approx 10% through 100%.
- Potentiometers can control specified fixtures or the entire R/S and C/S
of the bus.
- Can easily be configured to emit 100% light output when the door opens for
safe passenger entry and egress.
Programmable Light Output Option
(customized light % output, upgrade system)
Features on board programmable interior lighting control (ILC) unit that
allows for automatic adjustment of each light fixture‘s % of light output
for Day, Overcast and Night Modes with door open or closed.
- Allows each fixture to adjust light output to a specific level per fixture based on
predetermined inputs utilizing our “End User” ILC programmable control module.
- The ILC holds 2 user defined pre-set programs, an “in bus” simulation program and a 100%
light output default program.
- The ILC allows for adjustment of light on/off/dim dwell times from 0 – 5 seconds.
- Retains the ability for each fixture to Extinguish or Dim at preset light percentage with the
closing of the door.
- The ILC contains diagnostics to indicate fixture communication errors.
- Includes a photo sensor which automatically adjust the interior lighting per ambient
light conditions.
- Offers an optional back up battery system to light specified fixtures for emergency use.
The ILC communicates with:
- Vehicle via J1939CAN BUS:
- Detects: Light Switch and Door Position
- Light Fixtures via J1708/RS485 Network:
