Recessed ceiling lamp with rectangular flowers

The invention relates to a recessed ceiling light with *

Air-conditioning lights are known in the execution that the light is used not only for illumination but also for air conditioning the room below. Such lamps k'önnen in the usual Deckensysteiae be installed and together m ± t the adjacent ceiling tiles of the tinterdeeke a smooth ceiling lower surface, wherein these adjacent ceiling panels may also consist of sound-absorbing materials or plate shapes and luminaire and sheets into so-called modules summarized SJ- nd, which make it possible to change the partition walls of the room to be illuminated without impairing the lighting and air conditioning.

In the known arrangements of this type, it has proven to be disadvantageous that as a result of the increase the light intensity increases the temperature in the illuminated house, until heat dissipation from this EaM offers doing difficulties.

"" To remedy this, the invention proposes venting to provide openings or slots in at least two opposite frame legs, which - 'the entry of air from the illuminated room into the

Luminaries housed inside the luminaire, especially fluorescent tubes, related, so that not only the

Room heating, but also the lamp heat and the through
the metal parts of the luminaire reflected heat are dissipated into the space above the luminaire. Through this j | Arrangement, the thermosiphon effect from the room to be illuminated within the luminaire is further enhanced. K As with modern »high-performance lights with a light intensity of around 10C0 Lux and a power || Sales of around HO W jö qm bring a heat load of M 11.8 kcal per qm and hour, a special cooling is necessary when using fi known lights | to be provided or to design existing cooling systems corresponding to μ. When using the ^{fiction according to en il} Leuohte, the heat load can be reduced from 11, S to 1.7 kcal per square meter per hour based on measurements made, without even an additional one
Energy expenditure for air to be extracted would be required. the
lamp according to the invention therefore acts as a heat sole euse for the developed in the room to be illuminated

In a further development of the invention, the frame legs, which are provided with the ventilation according to the invention, are intended to be

The hollow profile can be made particularly simple in that it consists of an S-profile with a horizontal web and vertical leg nowie connected to the lower, outward-facing Solaenkel of this profile, the web and the lower part of the upper leg to complement the channel L -Profile is formed, the web of the S-profile having the lower inlet openings and the opposite, horizontal leg of the L-profile having the discharge openings from the frame leg. £ ί / * AOOQ f \

Here, the aforementioned guide bar on the free edge of the upward over the horizontal leg of the L-profile protruding, upper leg of the '3-profile be formed by folding and expediently about half the width of the S-profile, i.e. his Schenkels, have.

The lamp according to the invention can then be used at the same time for a further purpose, which is already was mentioned above »if you open the heat lock, as it is formed by the arrangement described above, only on two opposite one another Provides frame legs and on the two remaining legs, preferably for rectangular lights the longer legs, the air conditioning connects in a similar way. This also needs to be done accordingly the invention of the use of hollow profiles as composite hollow profiles, each with a top lying, possibly heat-insulated supply channel for the conditioned air and an underlying, non-insulated exit profile are formed, wherein the hollow profiles through each other through openings and the exit profile with the room to be illuminated adjustable openings is connected. These openings can preferably be formed by a slot running over the length of the frame leg.

For the purpose of draft-free adjustment of the exit direction of the air-conditioned air curtain from the

A K-profile has proven to be expedient for the outlet profile and for setting the quantity, in which a distance is provided between the straight and the angled legs, which allows the air-conditioned air to pass through. Here, a guide leg facing the straight leg should be bent on the lower edge of the angled leg, while an adjustable and lockable swivel bar allows the direction and amount of air conditioning to be adjusted without tools. According to the invention, this swivel bar is inside »! of the hollow profile so housed * that its pivot axis is on the inside of the straight leg at the height of the apex edge of the angle leg, the pivot bar having a width so that it extends approximately to the free edge of the guide leg of the hollow profile. If you swivel this slewing ledge all the way up, the air supply is shut off. If it is pivoted further down, the air passage increases, the air exiting essentially downwards or at an angle opposite to the direction of the pivot bar. If the free edge of the swivel bar gets into the lower outlet slot, the air curtain is deflected in the direction of the swivel bar, while when the bar is completely swung out, the air flow is directed essentially vertically downwards at full strength.

To complete the lamp frame according to the invention you can attach a horizontal support strip for the neighboring plate of the building module to the outside
