Reference excerpt

SGM Light A/S is a Danish manufacturer of LED lighting for the concert touring, entertainment, architectural, commercial, and industrial sectors. The company is based in Aarhus, Denmark.

History SGM Technology for Lighting was founded in 1975 in Italy, by Gabriele Giorgi and Maurizio Guidi — the company name a truncation of ‘Societa Gabriele Maurizio’. In the early days they were known for producing a diverse catalogue of products for the emerging disco industry — ranging from illuminated dancefloor modules, ‘bubblesmoke’ machines and controllers — from their base in Pesaro. In April 2009 ownership was passed by president Gabriele Giorgi and his daughter Alessandra to long-standing Italian pro audio company, RCF Group. Peter Johansen was brought in to head up R&D in late 2010 — marking his return to the industry following a ten-year absence, after earlier setting up Martin Professional which he subsequently floated on the Copenhagen Stock Exchange. He recruited many of his former R&D team and quickly relocated the operation to Denmark — to work on innovations for the entertainment and architectural segments. In February 2012 Peter Johansen formed a consortium to acquire the company from the RCF Group, renaming it SGM A/S. Peter Johansen was joined by the LED specialists from his Danish R&D team led by engineer Finn Kallestrup and former members of his Martin Professional sales force as well as some of the company's Italian personnel. With R&D, administration and after-sales based in Denmark, manufacturing initially took place at bases in Italy, Thailand, and China before being consolidated into a single, purpose-built factory in Denmark. To broaden its marketing reach, SGM has set up subsidiaries in key territories around the world, including SGM Lighting Inc based in Orlando, FL and serving the North American market, SGM Deutschland and SGM UK. In November 2015, SGM A/S was restructured as SGM Light A/S with new ownership and new capital from an Italian company, while maintaining the management, the entire team behind the company, the product portfolio, and the distribution network. In October 2019, Peter Johansen stepped down from his role as SGM Light's CEO. Three Executive Directors (Torben Balmer, Mikkel Falk, and Ulrik Jakobsen) managed the company until 2021, when Ulrik Jakobsen became SGM's CEO.

Entertainment Products SGM Light manufactures a wide range of IP65 or IP66 rated products for the entertainment industry. These products include moving heads, washes, strobes, blinders, and effect lighting products.

Architectural Products Besides the entertainment focused product range, SGM Light also develops and builds IP66 rated lighting fixtures for architectural installations. These fixtures are marked POI (Permanent Outdoor Installation) and specifically developed to fulfill the requirements of installations on buildings, bridges, cruise ships, etc.

Worked examples

Example 1 — a first encounter with SGM Light

Start with the simplest possible case. Write down what SGM Light claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to SGM Light before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about SGM Light ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of SGM Light

In research: SGM Light appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses SGM Light in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: SGM Light is common in secondary-school and first-year university syllabi. It links to neighbouring topics Electrical equipment manufacturers, so understanding it makes those chapters shorter.
In everyday life: Look for SGM Light outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
