Description

Lighting system with integrated air cleaning

The invention relates to a lighting system comprising at least one light source and at least one first hollow profile on which the light source is held.

In the field of room air cleaning, a distinction is generally made between three known types of devices with different air cleaning units: air washers, ionizers and filter units.

Filter units filter the room air through one or more filters

or filter media and are thus capable of the room air and small particles such as pollutants, gases, allergens and

To clean odors.

Air scrubbers filter coarse particles from the air in the room by binding them with water.

Ionizers generate negatively charged particles that bind to positively charged particles in the room air, making the particles heavy. you then sink to the ground and can be collected there or removed.

The device types listed above for room air purification each require an active ventilation system in order to guide an air flow of the room air to be cleaned to their air purification units and to clean them from them. For the

Power consumption of their required ventilation system thus incurred in addition to the cost of these types of equipment ongoing operating costs. In addition, noticeable noises occur during operation by the ventilation system. The appearance of such device types is usually not very appealing. In addition to their room air cleaning function, these device types generally have no functional added value.

Object of the present invention is to provide a lighting system with a

Air purification unit to reveal that is visually appealing, with little or no additional energy and noise level works and is easy to clean.

To achieve the object, the invention has the features of claim 1. Consequently, the first hollow profile has at least one air outlet opening and is held at an angle greater than or equal to 30 ° and preferably 40 ° ± 5 ° to the horizontal, wherein due to convection, an air flow from at least one air inlet opening flows through the first hollow profile to the air outlet opening and wherein Air flow is passed through an air cleaning unit and cleaned by just this.

The particular advantage of the invention is that by the heat emitted by the light sources during operation and by the oblique arrangement of the first

Hollow profiles a sufficient flow of air through the lighting system flows, so that the surrounding air without or with low energy

Extra effort is cleaned by the air cleaning unit.

The core idea of the invention is insofar as to generate a sufficient air flow due to natural convection to the room air by means of

Clean air cleaning unit. According to a preferred embodiment of the invention, the first hollow profile is held on at least one second hollow profile, wherein the second hollow profile

is preferably held vertically and / or on a stand. As a result, the illumination system according to the invention can be realized in the form of a visually appealing floor lamp or desk lamp. The use of hollow profiles allows an internal cable routing and is basically well suited as a flow channel for a required airflow from the air cleaning unit. As a result, the lighting system according to the invention can be realized in a slim and visually appealing design.

According to a development of the invention, the air outlet opening is provided above the light source and the air inlet opening below the light source, the air cleaning unit being provided between the air inlet opening and the air outlet opening and / or designed in one piece with the same. This arrangement ensures that the heat emitted during operation of the light source from the in the

Hollow profiles and / or guided in the base air is taken and this flows upwards due to natural convection to the air outlet. At the same time, ambient room air flows over the air inlet opening, being filtered by the air cleaning unit. It is also conceivable that the

Air cleaning unit is provided above the light source, in which case the heated and outflowing air is cleaned.

According to a development of the invention, the air cleaning unit is removable and / or comprises a drawer-shaped filter body with a filter medium held therein and preferably a filter fabric. This allows the

Air purification unit or the filter medium received therein can be replaced or cleaned with little effort if necessary.

According to a development of the invention are in the base two or more

Air cleaning units and / or air inlet openings provided. Thus, an increased air flow to room air can be cleaned and / or as a cooling for the

Light sources are used.

According to a development of the invention connecting means for mounting on a ceiling and preferably wire ropes are provided as connecting means. The Lighting system according to the invention can thus be realized in the form of a visually appealing ceiling lamp.

The shape of a wall lamp in which the inventive

Lighting system is mounted on a wall via suitable connecting means is also conceivable.

According to a development of the invention, a fan for air supply is provided in the base and / or in the first hollow profile and / or in the second hollow profile. By means of the fan, an increased air flow can be sucked in to room air and in the

Air cleaning unit cleaned or for increased cooling of the

Be used light source.

According to a development of the invention, a switching arrangement for the selectable switching on of the fan and / or the light source is provided. With sufficient natural convection, the operation of the fan may not be necessary. Using the specified switching arrangement, the fan can be switched off for this case and save energy. However, the fan can optionally be added to the light source. Likewise, the fan can be used for cleaning the room air by means of the air cleaning unit when the light source is turned off, which is the case, for example, at bedtime. Thus, a continuous cleaning of the air at a reduced energy consumption can be ensured.

According to a development of the invention, a transformer and / or a power supply are provided. These are usually necessary for the operation of the light source or the fan and generate additional waste heat, which can also be used for natural convection and thus for increased air flow. The prerequisite for this is that the transformer or the power supply dissipates waste heat to the internal air in the hollow sections and / or in the base.

According to a development of the invention is an air flow sensor and / or a

Temperature sensor and / or an air humidity sensor and / or a particle sensor, in particular a fine dust sensor and / or a smoke sensor provided. Such sensors can monitor the quality of the surrounding room air, whereby the lighting system according to the invention has an additional function. By means of an air flow sensor, the filter or cleaning effect of the air cleaning unit can be monitored. The air flow sensor can report a reduced air flow or, conversely, an increased flow resistance, which is used, for example, as a result of an additional filter with a thick filter cake. In combination with a signal generator can thus a

Signal indication for replacing or cleaning the air cleaning unit are issued.

From the other dependent claims and the following description further advantages, features and details of the invention can be found. There mentioned features may be essential to the invention individually or in any combination.

The drawings are merely illustrative of the clarification of the invention and are not of a restrictive nature.

Fig. 5 shows the base of FIG. 3 in a plan view with hidden edges and Fig. 6 shows a second embodiment of an inventive

Lighting system mounted on a ceiling in a side view with hidden edges.

A first exemplary embodiment of a lighting system according to the invention as a floor lamp is shown in FIGS. 1 to 5. This lighting system according to FIGS. 1 to 5 comprises as essential shaping components a first hollow profile 1, which is held obliquely and preferably at an angle of 40 ° to a vertical second hollow profile, and a cylindrical base 4 into which the second hollow profile 2 opens and which serves to set up the lighting system on a substrate. On the first hollow section 1, a light source 5, preferably a high-power light emitting diode, held. If necessary, the necessary for the light source 5 electrical lines are preferably in the interior of the hollow sections 1, 2 to a transformer or to a power supply, which is preferably provided in the base 4 or in the lower region of the second hollow section 2.

In addition to a light-emitting function, the illumination system according to the invention is used for cleaning contaminated room air. For this purpose, an air cleaning unit 3 is provided which, in the exemplary embodiment of the lighting system according to FIGS. 1 to 5, is provided in the base 4 directly behind an air inlet opening 7. The air cleaning unit 3 is intended in particular to bind solid particles such as, for example, pollen, flower, house dust, fine dust or the like from the ambient air. This results in an improved room climate, which is of great interest for allergy sufferers, for example. For this purpose, the air cleaning unit 3, for example, an ionizer and / or preferably a filter unit with a filter medium, such as a filter fabric, have. The air cleaning unit 3 is in the embodiment of the lighting system according to the invention according to FIG. 1 to FIG. 5 designed drawer-shaped and integrally with the air inlet opening 7 and removable from a correspondingly shaped recess in the base 4. As a result, the air cleaning unit 3 or the filter medium can easily be exchanged and / or cleaned if necessary. In order to guide the room air to be cleaned by the air cleaning unit 3, the hollow sections 1, 2 and the base 4 are designed to carry out an air flow. The surrounding room air is from the shell side held in the base 4 air inlet opening 7 through the air cleaning unit 3 and from there on

corresponding channel recesses in the base 4 in the hollow sections 1, 2 out to a provided in the upper region of the first hollow section 1 air outlet opening 7. During operation, in particular, the waste heat generated by the light source 5 and by the transformer or the power supply generates natural convection. The air cleaned by the air cleaning unit 3 and warmed up due to the waste heat reduces its density and flows inside the hollow sections 1, 2 upwards and out of the intended air outlet opening 8 into the environment. For a good discharge of air in particular the vertical or obliquely upward pointing orientation of the hollow sections 1, 2 is crucial. It creates a negative pressure in the hollow sections 1, 2 and the base 4, which leads to that at the

Air inlet opening 7 is sucked from the environment an air flow.

The natural convection also ensures an improved cooling of the light source 5, which is necessary in particular for light-emitting diodes in order to realize a long service life. Thus, costs for a complex cooling of the light source 5 can be saved.

In addition, this embodiment includes the inventive

Lighting system according to Fig. 1 to Fig. 5 a fan 6, which is preferably provided concentrically to the second hollow section 2 and viewed from the path of the air flow behind the air cleaning unit 3 in the base 4. The fan 6 can be switched on via a suitable switching arrangement optionally to the light source 5 or operated individually. By the fan 6 can in common operation with the light source 5, an increased air flow of room air in the

Infuse lighting system, resulting in the cleaning effect of

Air purification unit 3 and the cooling effect for the light source 5 increases. When the light source 5 is switched off, for example at bedtime at night, the room air can be further cleaned by the operation of the fan 6. The fan 6 can be so dimensioned and housed in the base 4 that its operation with a very low noise level and almost imperceptible feasible. FIG. 6 shows a second exemplary embodiment of the illumination system according to the invention as a suspended ceiling lamp in a side view with hidden edges. As the main component giving shape this embodiment comprises the first hollow profile 1, which is mounted on a ceiling 10 via connecting means 9 and preferably wire cables. In this case, the first hollow section 1 depends obliquely and at an angle of preferably 40 ° to the ceiling 10. By this arrangement, ambient air can flow through the first hollow section 1, which has frontal openings 7, 8 for this purpose. In the lower region of the first hollow profile 1, the air inlet opening 7 is provided on the front side. In the upper region of the first hollow profile 1, the air outlet opening 8 is provided on the front side. Between the openings 7, 8, the air cleaning unit 3 and two light sources 5 are held in the first hollow section 1. The light sources 5 are facing away above the air cleaning unit 3 and from the ceiling 10 and positioned radiating down. The waste heat of the light sources 5 generates a natural convection in the interior of the first hollow profile 1, wherein the oblique orientation of the first hollow profile 1 in this case is crucial for sufficient air flow. Thus, room air can flow through the air inlet opening 7 through the air cleaning unit 3, be cleaned and flow out of the air outlet opening 8. The air cleaning unit 3 is preferably removably held in a correspondingly shaped and frontally provided recess of the first hollow section 1.

Lighting system according to the invention. It will only be the

Distinguishing features of the following on the first embodiment

Embodiments explained to the first embodiment. Incidentally, the embodiments agree.

The invention is not limited to the illustrated embodiments of the

Lighting system limited. For example, while retaining the inventive idea, embodiments of the lighting system are conceivable in alternative design variants. Thus, the lighting system in the form of a

Floor lamp without a stand 4 be realized and in the lower part of its second hollow section 2, the air inlet opening 7 have. It is also conceivable to constructively connect a plurality of first hollow profiles 1, wherein the thus formed Lighting system has a connected to all first hollow sections 1 air cleaning unit 3 and / or fan 6 and / or air outlet 8 and / or an intermediate piece. The intermediate piece may for example also be provided between first hollow profiles 1 and / or second hollow profiles 2. It is conceivable that the intermediate piece is a joint which connects the hollow profiles 1, 2 adjustable with each other. The intermediate piece can also function as a supporting or receiving and / or replaceable element for individual components, for example for the air cleaning unit 3, of the illumination system according to the invention.

It is also conceivable to equip the illumination system according to the invention with sensors for monitoring the air cleaning, in particular with an air flow sensor. The air flow sensor detects a falling air flow due to increased flow resistance of a clogged filter unit of the

Air cleaning unit 3 occurs. The reduced air flow indicates that the filter unit or its filter medium must be replaced or cleaned in order to ensure high filter performance again.
