What does LED downlight mean?
First, LED (light-emitting diode) could be explained as a semiconductor diode that emits light when a voltage is applied to it and that is used especially in electronic devices (as for an indicator light). Second, a downlight can be defined as a light that has been recessed into a ceiling and that throws light downwards in a narrow beam. Downlight also can be called recessed lights. When it turns on, it looks like light is shining down out of the ceiling. Downlights are comprised of a housing that is inset into the ceiling, the bulb, and a transformer (if necessary) in order to convert the power voltage into one that is safe for the downlight to use.What the downlight used for?
Downlights are the all-purpose of lighting fixtures as they are used as a component of a good lighting plan in most lighting projects. A downlight is most often used to provide general lighting in a specific space. Therefore, which kind of the LED downlight is that you need in your space? Let’s follow me to know some common kinds of downlights and solve your confusions.If you worry about the fire safety, you could choose fire rated downlights.
What is fire rated downlights？
Fire rated downlight is a kind of downlights that seals the hole cut into the ceiling and helps slow down the spread of fire. When you cut a hole into a ceiling to install recessed lights, a potential fire hazard is created. Once the house happened fire, the downlight hole is like an open gateway that let the fire spread through. However, Fire rated downlights could seal off the hole so that block the spread of fire. Therefore, you could pick fire rated downlights to reduce the potential fire risk.
If you also worry about the building insulation material issue, you could choose the IC rated downlights.
What is IC rated downlights？
An IC rated downlight means that building insulation that can be continuously exposed to 90°C can safely abut and cover the luminaire.In 2011, changes to the recessed luminaires standard were made. These introduced new classes of recessed downlights that eliminate clearances and ensure safer installation with surrounding thermal insulation. It aims to ensure that "a downlight with not be unsafe if thermal insulation, which is specified as safe to use with downlights,is installed incorrectly"
What does Insulation Covered mean for IC rated downlight?
All products manufactuered or imported into these markets must be one of the five new classes. Only four of the five classes may be used in residential buildings Any residential ciass downlight must be safe if accidentally covered with building insulation.Insulation
Air is a good insulator in the absence of convection. Many insulation materials function simply by having a large number of air filled pockets which prevent convection e.g.just like animal's feathers and fur, building insulation mats and biankets use these air pockets to contain heat and this is measured as resistance values(R values). New housing now requires high mandatory"R"values. Government and Council programmes are also encouraging large scale upgrades of existing homes to the same high"R”values.This means that thicker insulation is now being installed.What does Insulation Covered mean for thermal insulation in residential buildings?
Buildings will be more thermally efficient Installed insulation must maintain its structural integrity at specific temperatures Insulation material must typically pass Needle Flame Test method on all surfaces Downlight manufacuters must state what building/thermal insulation is safe and compatible to use with downlight.If you are struggling to the bathroom lights problems, you could consider Bathroom/IP65.
What is IP65 LED downlights?
IP65 LED downlights is a specifical downlight that could against water jets and dust ingress. You could watch the following viedo to know more detail about IP65 LED downlights. It will show Vertex's IP65 LED downlights in details.IP65 LED downlights is usually installed in a zone 1 area of bathroom. You may ask what’s zone 1 area of bathroom? According to the industry-standard, the bathroom was divided into three zones.
These three zones are as follows:
Zone O: -Inside the bath tub or shower tray.Any fitting going in this area must be low voltage(12v max)and have an IP rating of at least IP67.
Zone 1: -Directly above the bath tub or shower tray to a height of 2.25m from the floor. Products should be IP44 or higher and if the fitting is 240v a 30ma RCD must be used to protect the circuit.
Zone 2: -Over the bath tub or shower tray above zone 1. It also covers the area stretching 0.6m outside the perimeter of the bath and to a height of 2.25m from the floor and the area around the wash basin,within a 60cm radius of any tap. Lighting in this area should be at least IP44.
