Easing Lighting System Design with Online Tools

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. 

 Specifying basic system parameters – the first step when using the Lighting System Creator

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.

Specifying basic system parameters – the first step when using the Lighting System Creator
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.


Selecting the opposite
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 selectedsuccessive 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.
