About 5% of the electric energy is converted in to light.

Compactnes and a wide variety of these lamps offer huge possibilities for creative lighting. Halogen lamps make colours come to life and produce attractive shining effects. They remain bright at an even level during their entire life span, while being more energyefficient than standard light bulbs. For example, to achieve a luminous flux of 960 lumen a light bulb needs 75 W where a halogen lamp only needs 50 W.<\/span><\/p><h1 style=\"font-size: 2.38889rem; font-style: normal;\"><span style=\"font-size: 43px; color: #d10000;\">Gas-discharge lamps\u00a0<\/span><\/h1><p><span style=\"color: #000000;\">The basic principle of this lamp is the electric discharge.

On top of that, the light is produced on a surface that is no larger than a coin. A low amount of thermal radiation, incredible colour rendering and a long life span are benefits of modern HIT lamps.

They are semiconductors that transfer an electric current in to light. They emit red, orange, yellow, green of blue light. White light is created using a special LED technology<\/span><\/p><p><span style=\"color: #000000;\">LED's give designers a large degree of liberty in creating innovative light. The many different colours, compact shapes and versatility of different modules all contribute to this.<\/span><\/p><p><span style=\"color: #000000;\">Aside from its decorative qualities LED's use a low amount of power, have long lifespans and low maintenance costs.

In contrast to light bulbs, LEDS emit one specific colour. The colour depends on the used materials, and goes from red to orange, yellow, green and finally blue. White light is made using luminescence. A blue LED excites a yellow emitting phosphorus, mixing both colours makes white light. The last couple of years have meant that LED efficiency has risen considerably. Depending on the colour 20lm\/W and more can be achieved. Voltage drop depends on the colour and is between 2V and 4V at a current of 70mA.<\/p><p><span style=\"color: #000000;\">Technology is developing rapidly and LED is no exception. Because of this reason it is possible that information that is provided within the product specifications has aged. Do not hesitate to contact us to learn about the correct light source of the time.<\/span><\/p><h1><span style=\"color: #d10000;\">Influence of temperature<\/span><\/h1><p class=\" translation-block\">The light output of LED's declines when temperature rises. Yellow LED's are more sensitive to temperature than green LED's. Lower emittances of light as a consequence of high temperature is reversible and not a degradation. Maximum environmental temperatures are 100 degrees celcius, this temperature should not be exceeded.<\/p><p><span style=\"color: #000000;\">LED modules are constructed from a collection of individual LED's, mounted on a PCB with active or passive power stabilization. Different kinds of module families have a lightconductor or a lens as an option. PCB's are rigid or flexible. Modules with flexible print make it possible to make three-dimensional lightconstructions.<\/span><\/p><table><tbody><tr><td width=\"124\"><span style=\"color: #000000;\">Light colour number

White light is made using luminescence. A blue LED excites a yellow emitting phosphorus, mixing both colours makes white light. The last couple of years have meant that LED efficiency has risen considerably. Depending on the colour 20lm\/W and more can be achieved. Voltage drop depends on the colour and is between 2V and 4V at a current of 70mA.<\/p><h1><span style=\"color: #d10000;\">Influence of temperature<\/span><\/h1><p class=\" translation-block\">The light output of LED's declines when temperature rises. Yellow LED's are more sensitive to temperature than green LED's. Lower emittances of light as a consequence of high temperature is reversible and not a degradation. Maximum environmental temperatures are 100 degrees celcius, this temperature should not be exceeded.<\/p><p><span style=\"color: #000000;\">LED modules are constructed from a collection of individual LED's, mounted on a PCB with active or passive power stabilization. Different kinds of module families have a lightconductor or a lens as an option. PCB's are rigid or flexible. Modules with flexible print make it possible to make three-dimensional lightconstructions.<\/span><\/p><table><tbody><tr><td width=\"124\"><span style=\"color: #000000;\">Light colour number Philips<\/span><\/td><td width=\"119\"><span style=\"color: #000000;\">Osram<\/span><\/td><td width=\"120\"><span style=\"color: #000000;\">New lamp coding<\/span><\/td><td width=\"120\"><span style=\"color: #000000;\">Colour rendering index<\/span><\/td><td width=\"120\"><span style=\"color: #000000;\">Colour temperature<\/span><\/td><\/tr><tr><td width=\"124\"><span style=\"color: #000000;\">82<\/span><\/td><td width=\"119\"><span style=\"color: #000000;\">41<\/span><\/td><td width=\"120\"><span style=\"color: #000000;\">827<\/span><\/td><td width=\"120\"><span style=\"color: #000000;\">85<\/span><\/td><td width=\"120\"><span style=\"color: #000000;\">2700 K<\/span><\/td><\/tr><tr><td width=\"124\"><span style=\"color: #000000;\">83<\/span><\/td><td width=\"119\"><span style=\"color: #000000;\">31<\/span><\/td><td width=\"120\"><span style=\"color: #000000;\">830<\/span><\/td><td width=\"120\"><span style=\"color: #000000;\">85<\/span><\/td><td width=\"120\"><span style=\"color: #000000;\">3000 K<\/span><\/td><\/tr><tr><td width=\"124\"><span style=\"color: #000000;\">84<\/span><\/td><td width=\"119\"><span style=\"color: #000000;\">21<\/span><\/td><td width=\"120\"><span style=\"color: #000000;\">840<\/span><\/td><td width=\"120\"><span style=\"color: #000000;\">85<\/span><\/td><td width=\"120\"><span style=\"color: #000000;\">4000 K<\/span><\/td><\/tr><tr><td width=\"124\"><span style=\"color: #000000;\">\u2013<\/span><\/td><td width=\"119\"><span style=\"color: #000000;\">11<\/span><\/td><td width=\"120\"><span style=\"color: #000000;\">860<\/span><\/td><td width=\"120\"><span style=\"color: #000000;\">85<\/span><\/td><td width=\"120\"><span style=\"color: #000000;\">6000 K<\/span><\/td><\/tr><tr><td width=\"124\"><span style=\"color: #000000;\">86<\/span><\/td><td width=\"119\"><span style=\"color: #000000;\">\u2013<\/span><\/td><td width=\"120\"><span style=\"color: #000000;\">865<\/span><\/td><td width=\"120\"><span style=\"color: #000000;\">85<\/span><\/td><td width=\"120\"><span style=\"color: #000000;\">6500 K<\/span><\/td><\/tr><tr><td width=\"124\"><span style=\"color: #000000;\">92<\/span><\/td><td width=\"119\"><span style=\"color: #000000;\">\u2013<\/span><\/td><td width=\"120\"><span style=\"color: #000000;\">927<\/span><\/td><td width=\"120\"><span style=\"color: #000000;\">95\/96<\/span><\/td><td width=\"120\"><span style=\"color: #000000;\">2700 K<\/span><\/td><\/tr><tr><td width=\"124\"><span style=\"color: #000000;\">93<\/span><\/td><td width=\"119\"><span style=\"color: #000000;\">32<\/span><\/td><td width=\"120\"><span style=\"color: #000000;\">930<\/span><\/td><td width=\"120\"><span style=\"color: #000000;\">95\/96<\/span><\/td><td width=\"120\"><span style=\"color: #000000;\">3000 K<\/span><\/td><\/tr><tr><td width=\"124\"><span style=\"color: #000000;\">94<\/span><\/td><td width=\"119\"><span style=\"color: #000000;\">22<\/span><\/td><td width=\"120\"><span style=\"color: #000000;\">940<\/span><\/td><td width=\"120\"><span style=\"color: #000000;\">95\/96<\/span><\/td><td width=\"120\"><span style=\"color: #000000;\">4000 K<\/span><\/td><\/tr><tr><td width=\"124\"><span style=\"color: #000000;\">95<\/span><\/td><td width=\"119\"><span style=\"color: #000000;\">12<\/span><\/td><td width=\"120\"><span style=\"color: #000000;\">950<\/span><\/td><td width=\"120\"><span style=\"color: #000000;\">98<\/span><\/td><td width=\"120\"><span style=\"color: #000000;\">5000 K<\/span><\/td><\/tr><tr><td width=\"124\"><span style=\"color: #000000;\">96<\/span><\/td><td width=\"119\"><span style=\"color: #000000;\">72<\/span><\/td><td width=\"120\"><span style=\"color: #000000;\">965<\/span><\/td><td width=\"120\"><span style=\"color: #000000;\">97<\/span><\/td><td width=\"120\"><span style=\"color: #000000;\">6500 K<\/span><\/td><\/tr><\/tbody><\/table>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-72b2f66 elementor-widget elementor-widget-spacer\" data-id=\"72b2f66\" data-element_type=\"widget\" data-widget_type=\"spacer.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<div class=\"elementor-spacer\">\n\t\t\t<div class=\"elementor-spacer-inner\"><\/div>\n\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"<p>Over lichtbronnen\u00a0 Voorheen waren lichtbronnen onderverdeeld in de volgende hoofdgroepen.
