Some exemplary types of light source  702  include an incandescent lamp, a fluorescent lamp, a halogen lamp, a light-emitting diode (LED) and the like, and any combination thereof. 
     According to one embodiment, the light source  702  is configured to serve as a decoration for the ashtray  1 . According to another embodiment, the light source  702  is configured to allow a user, for example a smoker, to visually notice the ashtray  1 , for example when it is dark. According to one embodiment, the light source  702  is configured to permanently emit light. According to another embodiment, all aspects of light emission by the light source  702 , for example duration of light emission, light intensity, color of emitted light, color pattern of the emitted light and the like, may be controlled. According to another embodiment, all aspects of light emission by the light source  702  may be controlled by the control module  20 . According to yet another embodiment, all aspects of the light emission by the light source  702  may be controlled in response to activating signals detected by the detecting module  10  in a manner described above. For example, detection of a lit cigarette in the vicinity of the ashtray  1 , for example by a heat sensor, cause the heat sensor to transmit a signal to the control module  20  indicating that a lit cigarette is adjacent to the ashtray  1 . In response to this signal received by the control module  20 , the control module  20  mat send a signal to the light source  702  to start emitting light. Similarly, when the cigarette is removed from the vicinity of the ashtray  1 , the emission of light by the light source  702  may be shut-off as a result of a similar sequence of events. It should be noted though, that this is only an example of the way in which light emission by the light source  702  may be controlled by the control module  20 , and that any type of control pattern known in the art is under the scope of the present subject matter. 
     It should be obvious to a person skilled in the art that in light of the aforementioned embodiments, the light source  702  may be signally connected to the control module  20 . 
     It should be further understood that the ashtray  1  may comprise a power source configured to supply power for the light source  702 . Not only that, the power source may be configured to supply electrical energy to any component of the ashtray  1  that may require supply of electrical energy, for example components of the control module  20 , the air intake element, for example the fan  302 , and the like.

     According to one embodiment, illustrated in  FIG. 6 , the ashtray  1  may comprise at least one notch  184  on the edge of the upper opening of the ashtray  1 , at the air entry side  12  of the ashtray  1 . Each notch  184  is configured to hold a cigarette  500 . 
       FIG. 7  schematically illustrates, according to an exemplary embodiment, a block diagram of a control module. According to one embodiment, the control module  20  may comprise a processor  202 . Any processor  202  known in the art is under the scope of the present subject matter, for example a central processing unit (CPU). According to another embodiment, the control module  20  may further comprise a memory  204 . Any memory  204  known in the art is under the scope of the present subject matter, for example a machine-readable medium, also known as computer-readable medium (CRM). The memory  204  is configured to store data, and the processor  202  is configured to process data. The control module  20  as a whole is configured to receive data or signals, process data and transmit data or signals, as known in the art. 
     According to one embodiment, the control module  20  is configured to read activating signals received from components, for example sensors, of the detecting module  10 . According to another embodiment, the control module  20  is configured to adjust activity of the air intake module  30 , and alternatively the activity of the air refreshing module  60 , in response to activating signals received from the detecting module  10 . For example, in response to an activating signal indicating that there is a cigarette adjacent to the ashtray  1 , that is received from the detecting module  10 , the control module transmits a signal to the air intake module  30  that causes the air intake module  30  to start taking in air  700 , for example by starting the action of a fan  302  that was in rest. In another example, the air intake module  30  takes air  700  into the ashtray  1  continuously. When the detecting module  10  detects a cigarette adjacent to the ashtray  1 , the detecting module  10  transmits a signal to the control module  20 , and in turn the control module  20  transmits a signal to the air intake module  30  to increase the speed of taking air  700  into the ashtray  1 , for example by increasing the rotation speed of a fan  302 , in order to enhance the purification of the air  700 , which contains a larger amount of smoke due to the cigarette. According to another embodiment, the control unit  20  determines the duration of activity of the air intake module  30 , for example the duration of activity of the air intake module  30  after a cigarette is removed from the vicinity of the ashtray  1 . Similarly, according to yet another embodiment, the control module  20  controls changes in speed of taking in air by the air intake module  30  in response to changes in conditions detected by the detecting module  10 , for example decreasing the rotation speed of the fan  302  in response to detecting a decrease in the level of smoke in the air  700 . 
     According to an additional embodiment, the control module  20  is configured to control the activity of the light source  702 . For example, the control module  20  may switch the light source  702  on and off, or control the intensity of light emitted from the light source  702 , and a combination thereof, in response to signals received from the detecting module  10 . In another example, a light sensor of the detecting module  10  detects that the area of the ashtray  1  is dark. A corresponding signal is transmitted from the detecting module  10  to the control module  20 , and in turn the control module  20  transmits a signal to the light source  702  causing the light source  702  to turn on. 
     According to a further embodiment, an audio signal may be received by a microphone, which is a component of the detecting module  10 . For example the audio signal may be a voice command to activate the air freshening module  60 . In turn, the detecting module  10  transmits a corresponding signal to the control module  20 , and in response the control module  20  transmits a signal to the air freshening module  60  to release perfume to the air  700  passing through it or adjacent to it. 
       FIG. 8  schematically illustrates, according to an exemplary embodiment, a block diagram of components participating in a voice recognition and activation cycle. According to one embodiment, the detecting module  10  comprises a microphone  102  configured to receive a voice command  800 , for example from a user, and convert the voice command  800  to a voice command electronic signal corresponding to the voice command  800 . According to this embodiment, the control module  20  comprises a voice command interpreter  206  configured to interpret the voice command electronic signal; and a set of commands  208 , stored for example in the memory  204 . Once the voice command interpreter  206  receives the voice command electronic signal from the microphone  102 , the voice command interpreter  206  interprets the voice command electronic signal, and selects from the set of commands a control command  2082  that corresponds to the voice command  800 . Once an appropriate control command  2082  is selected from the set of commands  208 , the control module  20  controls a component of the ashtray  1  accordingly. For example, when the voice command  800  is “turn light on”, in response to the selected corresponding control command  2082  the control module  20  transmits a signal to the light source  702  prompting the light source  702  to turn on. 
     Some exemplary control commands  2082  that are part of the set of commands  208  include: “Turn fan on”, “Turn fan off”, “Speed up fan”, “Slow down fan”, “Turn light on”, “Turn light off”, “Brighten light”, “Dim light”, “Increase sensitivity of sensor”, “Decrease sensitivity of sensor”, “Autosense mode”, “Manual mode” and the like. It should be noted that this list of control commands  2082  which are part of the set of commands  208  is only exemplary, and that any type of control command  2082  is under the scope of the present subject matter. 
     Regarding the exemplary control commands  2082  “Increase sensitivity of sensor” and “Decrease sensitivity of sensor”, they may be relevant to a situation when a user wishes to adjust the sensitivity of a sensor, for example a sensor configured to detect a cigarette in the vicinity of the ashtray  1 . For example, a user wants the fan  302  will be turned on when a cigarette is in a large distance from the ashtray  1 . Thus, the user sends the voice command “Decrease sensitivity of sensor”. As a result, the corresponding control command  2082  that is selected from the set of commands  208  causes the sensor to decrease the sensitivity of the sensor, and as a result the sensor detect a cigarette when it is in a large distance from the ashtray  1 . Similarly, the control command  2082  “Increase sensitivity of sensor” causes ultimately the sensor to detect a cigarette which is in a closer vicinity to the ashtray  1 . 
     According to one embodiment the set of commands  208  may include control commands  2082  for stopping or starting an automatic operation of a component of the ashtray  1 , for example the fan  302 . For example, a user may transmit a voice command  800  saying “Automatic fan” in order to start an automatic operation of the fan  302 , which adjusts the speed of rotation of the fan  302  according to conditions in the vicinity of the ashtray  1 . In another example, the set of commands  208  may include control commands  208  for selecting a mode of a program for automatic adjustment of a speed of rotation of a fan  302 . For example, a user may transmit the voice command  800  “continuous fan speed” or “Two-speed fan” to specify whether the fan  302  operate continuously, or alters between two predetermined speed level of rotation in response to conditions in the vicinity of the ashtray  1 .
