Reflectors and louvres

Reflectors for fluorescent lamps make it possible to reduce the loss of light due to dispersion inside the luminaire. They concentrate light and direct it in a specific direction. They are usually made of properly formed metal sheet - aluminum or steel, which is anodized and polished to obtain the best optical properties. Thanks to this, the efficiency of light reflection is higher by several dozen percent, and the luminous flux is directed directly towards the illuminated surface or object, which in turn allows to reduce the number of light sources, and thus lower energy consumption. The best concentration of light is obtained with parabolic reflectors, although in many situations symmetrical or asymmetrical models made of sheet metal bent along clearly marked lines will be quite sufficient. Reflectors can already be installed in luminaires, although in many cases it is necessary to purchase them separately, which allows you to choose the model that is optimal for your needs. The reflectors can be purchased with clamps for fluorescent lamps, which additionally stabilize them in the luminaire.

Louvre luminaires are designed to eliminate glare and their design enables optimal interior lighting. They are mainly used in offices, where the phenomenon of glare can make work at monitor screens very difficult, but they are also readily used in schools, health care facilities, conference rooms, shops or workshops. The raster luminaire consists of reflectors and flat or V-shaped crossbars (louvres), whose task is to further break the luminous flux. It is worth knowing that in colloquial language entire frames are referred to as rasters .

How to choose fluorescent reflectors and louvres?

Louvers usually come in ready-made luminaires, while reflectors can be purchased separately and mounted anywhere.

When choosing louvre luminaires, you need to pay attention to the method of their installation, because there are models available on the market screwed directly to the ceiling, as well as flush-mounted models that can be easily installed in suspended ceilings. The latter are sometimes equipped with an additional frosted glass pane. This solution fits perfectly with flat ceiling surfaces. There are also models of luminaires that can be hung on the holders, thanks to which they will not be directly adjacent to the surface, e.g. a wooden ceiling or a ceiling beam or a supporting roof. These models are convenient in very high rooms, because they allow you to adjust the height of the lamps suspension - so that they optimally illuminate the surface under them.

Before buying, it is necessary to calculate the need for light in order to provide the best possible illumination of the surface from its sources, especially in the case of public facilities or workplaces, which must meet the requirements of standards regarding visibility at the workplace. Knowing the requirements such as light intensity, color index or lighting glare rating index, it will be easier to choose the model of the reflector or louvre luminaire necessary for a specific place.

What to look for when choosing reflectors and louvres?

When choosing reflectors, pay attention to the length of the fluorescent lamps used. The reflectors must be shorter than them to fit between the holders placed on the lamp holders. This is particularly important in the case of discharge lamps or double-sided LED lamps, where the sockets on both sides are responsible for powering the light source. In the case of single-sided lampholders, this is not so important, because the contacts for the phase and the neutral are placed in one mounting socket, therefore the use of a shorter fluorescent lamp may only be a mounting problem, not the one with the power supply.

In the case of raster, it is worth paying attention to the shape of raster currants. V-shaped structures ensure greater luminous efficiency of the luminaire and minimize glare. Good louvre luminaires are designed in such a way that the fluorescent lamp mounting sockets are masked by the extreme elements of the reflectors and louvers.
