AGI32

Ligman has a product instabase for AGI32 users for supporting their lighting design and planning. AGI32 offers comprehensive lighting calculations, ease of modeling, and fast high-quality renderings for almost any interior or exterior environment, including daylight. AGI32 is a computational program that performs numerical point-by-point calculations of incident direct or reflected light on any real surface or imaginary plane. Within this scope, it is used to predict or quantify the distribution of artificial or natural light in any environment. AGI32 is a simple yet extraordinary model builder capable of constructing almost any architectural environment. Vaults, domes, curves, slopes and extrusions are easily created, allowing you to accurately model the architectural elements you encounter on a daily basis. For those with existing 3D models, AGI32 can import 3D geometry via DWG or DXF.

Performance and Quality

LIGMAN luminaires are made from high grade quality die-cast aluminum ADC12 or LM6 with a low copper content allowing for extra strength & good thermal conduction. A high quality finishing process is preformed to withstand harsh outdoor conditions. The luminaires are sealed and protected against dust & water ingress into the optical chambers. Products are supplied with high grade non-aging gaskets for long life. Ligman luminaires are finished with a UV stabilized Polyester Powder Coating which is for excellent corrosion resistance to outdoor elements. The screw fine threads used in the housings are designed to assure tightness of the hardware & reduces the lost threading which would void the IP rating protection.

LED fittings are well engineered to obtain the highest level of thermal management to insure sustainability & maintain the LED lumen output performance until the end of LED life.


 

Optical and Distribution

Using modern optical software reflectors are designed to meet the highest level of performance giving precise light distribution. LED lenses are evaluated & refined to ensure precise control of the LED luminaire to meet various lighting distributions.


 

Enviromental Friendly

All LED components & equipment supplied in Ligman luminaires are selected to meet Eco-Friendly designs that provides less harmful impacts on the environment, due to the long recycle period of the product’s life cycle. Using LED sources helps reduce degrading effects such as pollution & carbon emissions (CO2).

Impact Resistance


The use of Joules (Newton metres-Nm) has been common for many years. More recently an IK rating normally used for electrical enclosures and cabinets (EN 50102:1995) has emerged as manufacturers apply it to their luminaires, as they also enclose electrical circuits. This chart compares both ratings:

IK Rating IK01 IK02 IK03 IK04 IK05 IK06 IK07 IK08 IK09 IK10
Joules of Energy 0.15j 0.23j 0.35j 0.5j 0.7j 1j 2j 5j 10j 20j

LED Technology

LIGMAN uses high-power LEDs and Chip-on-Board LED (COB).  This provides an advantage to the end user by obtaining the highest lumen output & most suitable light engine for the application.

The high quality of LEDs supplied with Ligman luminaires in conjunction with the highest efficiency lens & optical systems will provide the greatest distribution variety in the industry.

The highest quality of LEDs in the development of new luminaires applied with highest efficiency lens and optics system. LIGMAN provide most kind of industry distribution.

i.e. VN: very narrow, N: narrow beam, M: medium beam, W: wide beam, VW: very wide beam: E: elliptical beam, Type II, III and IV classification from IESNA for roadway and area lighting applications.

 

LED Spectrum


LEDs in LIGMAN luminaires provide optional:
neutral white (nw: W40, 4000K)  warm white (ww: W30, 3000K) warm (w: W27, 2700K).

All LEDs do not generate UV or IR radiation and have very low colour fading rate than conventional lamp.

 

LED Colour rendering


The colour rendering index (CRI or Ra) is a measure of how well a light source reproduces the colour of an object compared to a standard source. The index value is computed from how well the light source under test reproduces the colour of a number of standard colour swatches. Generally, colour rendering index between 80 and 90

is good and value between 90 and 100 considered as very good.

LIGMAN provide CRI value >80 for general outdoor as standard, however CRI >90 is optional upon the request.

 

LED Colour deviation


LIGMAN uses high-power LEDs and Chip-on-Board LED (COB) with 3 SDCM (3-Step MacAdam ellipes) as the highest standard which currently available in the market. The colour deviation between LEDs rarely found by human eye perception.

The SDCM (Standard Deviation of Colour Matching) value defined from

visual colour matching experiments its shows the standard deviation of the colour discrimination variations from a specific center on the xy chromaticity diagram based on ANSI engineer Davis Lewis MacAdam described. Increasing size of ellipse can classify the maximun colour deviation of light sources referred to as MacAdam ellips of a certain
step size SDCM.

 

LED Lumen maintenance


LIGMAN we designed our own LED light engine to maintain the thermal  below the critical temperature range and we properly input the optimum driving current when properly operated to ensure maximum luminous flux output together with serving a long life of LEDs.

The failure rate of LIGMAN LEDs is less than 10% after 50,000 hours. LIGMAN uses LEDs with the specification of L80/B10 at 50,000h, this means that after 50,000 hours, at least 90% of the LED still achieve 80% of their original luminous flux.

 

TM-30-15 (LATEST)


TM-30-15 is the latest method adopted by the Illuminating Engineering Society for quantifying colour rendering properties of light sources,  these results distinguish both colour fidelity and colour gamut and provides a framework for interpreting chroma and hue shift associated with light sources.

In keeping with the new measurement standards and meeting market requirements Ligman Lighting now provides TM-30-15 as well as CIE Ra and CIE R9 reports.

 

LIGMAN dedicated and focus on quality and design of luminaires in conjunction with well selected the highest grade of component integration with our knowledges and technologies to the end-users. We are continuously improving, evolving with new inspirations, new designs, finishes and innovative technologies.

The process of the luminaire creation integrates by inspirations, designs,  usage functions, new technologies.

LIGMAN uses high corrosion resistance, low copper content aluminium alloy ADC 12 for heatsinks on its LED products. This material is used in automotive industry for mechanical strength and excellent thermal dissipation, ideally suitable for low and high ambient temperature applications. LIGMAN also verify heatsink design thru thermal imaging before commencing commercial production. Due to best thermal verifications process we ensure less than 10% lumen depreciation at 50,000 hours.
