topic of this article - spotlights for ceilings.Is there any particular have the choice of luminaires when used near the PVC canvas?As they are installed?Let's deal.
To understand the selection criteria - let's first recall the circumstances in which to work our lighting equipment.It will, of course, about the tie-battens: rendered beyond the ceiling surface mounted fixtures quite standard and special restrictions on the shape and type of lamps have (see. Ceiling spotlights and chandeliers: the use and installation of a suspended ceiling).
- housing soffit located in confined spaces without ventilation.The ceiling is usually pulled over the minimum distance from the ceiling - simply because the ceiling height in a typical city apartment is limited to 270 centimeters.More often overlap and to do two and a half meters.
- In the vicinity of the light source is the canvas stretched ceiling.Typically, the PVC film is a maximum operating temperature of 60 degrees.
Note: actually ceilings perfectly survive short-term heating up to 80 degrees.Starting with 60 fabric softens and begins to sag.This explains the restriction specified by the manufacturer.
The conclusion is obvious.When selecting batten two factors are important :
- Minimum heat;
- maximum insulation lamp.
types of lamps
What you should pay attention, picking mounted in ceilings spotlight?First of all, on the type of the lamp therein.
The most common and cheapest type of lamp has two significant drawbacks :
- low energy efficiency.In the light of the best examples in turns only 2.6% of the electricity.
- follows from the first properties of a high heat for a fixed luminosity: the rest of the energy is used for heating the lamp and the environment around him.
use of incandescent light bulbs in combination with tension ceilings with certain disabilities .Lamp power must not exceed 40 watts.But this is not the best choice.
somewhat more interesting option: with the same electricity consumption galogenki provide greater luminosity .
In addition, most of the halogen lamp for spotlight has applied directly to the flask reflective layer: the luminaire does not need a separate reflector (see. Halogen ceiling lamps: features and types, scope).
However, halogen lamps - yet not a sample efficiency, and heat is still here.They can be used with limited power of 20 watts for PVC webs and 35 watts for fabric.
curious Guides manufacturers and dealers regarding the power limitations of the cost.For example, ceilings soffits manufacturer allows the installation of up to 35 watts galogenok even if the material is a PVC film.
same firm soffit ceilings can be used with any power LED lights.Why so?Did they do not produce heat?(See. Installation of LED illumination on the ceiling, the optimal solution)
On the practical side it is.Efficiency LED lamp reaches 22 percent, almost all the losses - at the power converter.In fact LEDs have an efficiency of 70 percent and above.
important nuance: LED lights can use your own converter for each batten, and the overall power supply to the entire group of fixtures.The second option which is preferable.And BP better place accessible for repair and replacement location.
How to install soffit - the ceilings because they can not be the basis for its rigid fixation ?
- in preparation for installation of a stretch ceiling is done wiring harness and installation of platforms for fixtures.In this case is a clear pattern with dimensions and distances.
- The web is then stretched.
- Similarly under each platform without any axial displacement on canvas glued reinforcing ring.When the glue will secure its connection to the web - the middle of the ring is cut at its inner edge.
- through the opening to the outside wiring is produced, which is connected to the soffit.
- then light is fixed to the platform.Decorative edging is placed last and hides reinforcing ring.For galogenok and incandescent lamps I am highly recommended to lay an additional one - two insulating rings.
- pose the lamp.All luminaires are aligned to the height.The level is not required: the slightest irregularities paintings are clearly visible.Lighting is ready.
soffits - not the only type of luminaires for suspended ceilings.Furthermore, they can be mounted in conjunction with other light sources - chandelier LED illumination along the perimeter and so on.It all depends on your imagination.Success in repairs!
