The technical intricacies light-emitting LED lighting
system style may be quite sophisticated. The inter-dependencies of style parameters like light flux, efficacy, lumen
maintenance, drive current, series/parallel light layout, compatible optics, compatible drivers, thermal
dissipation and others build the
calculation of system performance a hard method if performed manually. One easy amendment in one parameter may probably force the lighting Designer to consult the
datasheet for each alternative element thought of within the design so as to calculate the impact on the
system as an entire.
Multitude of design options for meeting the same target
specifications
|
The lighting elements market isn't static or mature. In fact,
solid state lighting technology continues to develop at an outstanding rate, and
thousands of latest LED's, lightweight engines, drivers, optics,
connectors and warmth sinks area unit introduced to the market once a year.
Until now, the light-emitting LED lighting market has felt this would
like for call support
tools by emotional component-based on-line simulation or choice tools. However, these
tools area unit depleted as a result of the solely method one lighting element at a time (i.e. solely the light-emitting LED from the light-emitting led vendor’s
tool or solely the
optic from the optic vendor’s tool or
solely the driving
force from the driving
force vendor’s tool) and not the lighting system as an entire.
Advanced style Tools provide an Improved method
The
LSC could be a new kind of proprietary on-line style tool that was developed with the lighting designer in
mind. This new on-line tool considerably will increase the lighting
designer’s productivity by combining thousands of sunshine sources, optics, drivers, sockets/connectors and
thermal management solutions with a
strong proprietary algorithmic
program to instantly and seamlessly develop luminary’s styles. This tool reduces days or
weeks of hard analysis efforts to a matter of
minutes.
The Element choice method
Finding the proper light
After specifying the essential system
parameters, then steps the
user through the complete element choice
process. This starts with the choice
of the
sunshine supply. The
default proprietary algorithmic
program
leverages supply LM-80 information
from all candidate to see the most
drive current (to minimize light source count price) to satisfy the target flux and efficacy at the most
unmoved temperature (to minimize the dimensions and cost of the thermal solution) so as to conjointly meet the L70 lumen maintenance target. As a
result, the user ne'er has to pre-select the sunshine supply drive current or
temperature to begin Associate in nursing analysis.
Setting
Filters
In
the downlight style, the user has set to
filter and show solely the sunshine sources which will meet the target
specifications with one light, which is able to eliminate prepackaged LED's from thought. The user then selected a COB light by
clicking on the radio button.
Refining the design parameters for the selected light source |
Optimizing style Parameters
Once the sunshine supply has
been selected, the user is ready to edit many parameters like light count, drive current, flux bin, forward voltage bin,
unmoved temperature and junction temperature wherever
all alternative parameters are recalculated in period of time.
What is more, for multi-light
supply applications like troffers wherever there's usually over one hundred mid-power LED's, the user is ready to modularize the system
by indicating the quantity of
boards that the lighting system ought
to contain.
system elements
Optics
The next step within the style
method is choosing the system
elements like optics, driver, connector/ socket, and thermal
answer. The optic is that the
initial system element to pick out
as a result of it's the potential to
alter the sunshine supply if
there’s no appropriate optic
for the chosen light. what is more, the optic will probably effect
on the driving force answer if a multi-light supply optic is chosen
as this kind of optic could need an adjustment within the light count
to mirror the quantity of sunshine sources that every optic will support.
Drivers
once the optic has been selected, successive step is to pick out the
sunshine supply driver.
The algorithmic program supports all sorts of sunshine supply drivers
from mounted current to
multi-current to completely programmable
drivers wherever the driving force output current can meet the luminaries target
specifications. The algorithmic
program considers the whole light forward voltage bin vary and also the impact
of temperature for displaying
appropriate drivers.
For multi-light supply and
multi-board applications, conjointly the
series/parallel light affiliation topology
similarly because the board-to-board
inter connection topology are show.
