- the mounting means 14 is configured such that it can be secured directly on the surface of a ceiling or wall.
- the illuminating portion 4 is movable in two ways. In a first way, the illuminating portion 4 is movable relative to the base portion 8 such that lighting from the illuminating portion 4 is downwardly shining to the floor, as represented by "X" in Fig. 2b .
- the lighting may be downwardly shining or it may be downwardly shining at an angle to the floor or towards an adjacent wall.

- a desired lighting effecting can be achieved by adjusting the configuration and position of the lighting module 2.
- the lighting system is configured such that the position of the lighting module 2 or the illuminating portion 4 can be adjusted remotely such that adjustment of the position of the illuminating portion 4 can be effected conveniently when the lighting module 2 is mounted on a ceiling out of normal reach by a user.
- the base portion 8 is provided with electronics having a receiver for receiving infra red signals emitted from a remote control unit assigned to the lighting system 2.
- Fig. 1a shows an electric circuit 16 of the receiver in this embodiment and
- Fig. 1b is a schematic diagram more broadly illustrating the logistics 18 of the working of the receiver.
- the base portion 8 is also provided with a motor means which acts on instructions from the electronics and can effect movement of the illuminating portion 4 such that lighting from the illuminator 13 can be directed downwardly or at an angle towards an adjacent wall surface.

- the lighting system when the lighting system is being manufactured it is provided with a default electronic designation in the form of a two-digit numeral although in other embodiments other suitable forms of alphanumerical representations may be used.
- the default designation in this embodiment is "00" for the lighting module 2 shown in Figs. 2a-c .
- a user can instruct the lighting module 2 to perform a desired performance remotely by using the remote control unit.
- the user merely requires changing the channel of the remote control unit channel "00", thus matching the designation "00" of the lighting module 2.
- subsequent signals emitted from a transmitter of the remote control can be received by the receiver and acted on by the lighting module 2.
- the subsequent signals may contain instructions to, for example, increase the brightness of illumination from the illuminator.
- the display 20 When the lighting module 2 is connected to a power supply, the display 20 will light up with the visual indication showing its electronic designation.
- a “global signal” refers to signals coding blanket instructions which are receivable, acceptable and acted on by all lighting modules within the system.
- the visual displays of all the lighting modules 2 will all light up, indicating their own electronic designations, which may be identical or different. It is to be noted that this particular global checking signal is receivable and acted on by all the lighting modules 2 in the vicinity.
- the electronic designation of a particular lighting module 2 can be changed by firstly connecting the remote control unit with the lighting module 2 with an electrical cable. Once they are connected, the existing electronic designation of the lighting module 2 can be revealed; and if it is to be changed a desired electronic designation can be input directly at the remote control unit and the new electronic designation is then transmitted to store at the memory of the lighting module 2 via the electrical cable.
- the same electronic designation or different electronic designations may be assigned to the modules 2 in a channel changing exercise for each lighting module accordingly.
- the electronic designation can also be changed remotely or wirelessly. This can be achieved by firstly checking the existing electronic designation assigned thereto as explained above. Then instructions by wireless signals for changing the existing electronic designation to a new electronic designation from the remote control unit are directed to the particular lighting module 2. This is achieved because the particular wireless signals contain coding with the existing electronic designation such that only the lighting module with this designation will respond to the signals, ie in this case to update its memory and record the new electronic designation.
- the remote control unit is set at a matching channel. For example, if the lighting module 2 with the electronic designation "01" is to be operated, then the remote control unit is to be set at the matching channel "01" such that operation signals from the remote control unit will contain coding for "01" and only upon receiving the operation signals containing the coding "01" would the particular lighting module 2 respond. In other words, in this scenario once the remote control unit is set at channel "01" the lighting module 2 with the electronic designation "01" is paired with the remote control unit such that the lighting module is in an operable state.
- the channel of the remote control unit is then set to "01". Then subsequent operation signals containing coding with the electronic designation "01" will be received and acted on by all the lighting modules (ie 2A and 2B) having the electronic designation "01".
- the designations of both the lighting modules 2A and 2B may for example be brought into consistency of eg "01" by connecting the lighting module 2B with the remote control unit with an electrical cable before the lighting module 2B is mounted on a surface. In other words, the designation is changed in a hard-wired manner. Once connected, the designation of the lighting module 2B is changed by the connected remote control unit as explained above. It is to be noted that the remote control unit is battery powered and the power is sufficient to effect the change and record the new designation "01" to the memory unit of the lighting module 2B.
- the designation "02" can still be changed wirelessly. This is achieved by firstly sending a remote infra red checking signal from the remote control unit to both the lighting modules 2A and 2B. This checking signal is globally read by the lighting modules. On receipt of this checking signal, visual indications showing the designations "01” and "02” will appear on the display screens of the lighting modules 2A and 2B, respectively.
- the relevant command on the remote control unit is provided, thus sending infra red signal corresponding to the command for changing and recording the designation of the lighting module 2B from "02" to "01” accordingly.
- both the lighting modules 2A, 2B and the remote control unit can be considered as paired. In this configuration, since both the lighting modules 2A and 2B carry the same designation "01", the lighting modules 2A and 2B are both paired with the remote control unit via the designation (or channel) "01".
- the lighting modules 2A and 2B carry the same designations, a user with the remote control unit can control them simultaneously. This is achieved by changing the channel of the remote control unit such that signals emitted therefrom are directed towards both the lighting modules 2A and 2B.
- the visual displays of both the lighting modules 2A and 2B will indicate "01" flashing.
- the user can then set the channel of the remote control to "01" such that subsequent signals from the remote control unit will be recognizable and acted upon by both the lighting modules 2A and 2B.
- each lighting module can be adjusted independently.
- the remote control unit is effected to emit an initial checking signal first.
- the visual displays of both the lighting modules 2A and 2B will be flashing with their designations "01" and "02", respectively.
- the user Since a specific performance of only the lighting module 2B is desired, the user will, on identifying the designation "02" shown on the visual display, set the channel of the remote control to "02" such that subsequent signals from the remote control unit will be directed to and acted on by the lighting module 2B.
- the user can change the channel of the remote control unit similarly as explained above in order to effect specific performance of the lighting module 2A.
- different number of lighting modules may be provided, with some of the lighting modules sharing the same designations while some do not.
- the same performance may be effected simultaneously.
- the lighting modules with separate or unique designations they may be controlled independently. It can be appreciated that when there are a plurality of lighting modules they are still be controlled in a similar manner.
- An embodiment of the lighting system according to the present invention is configured such that another global signal may be emitted by the remote control unit, and receivable and acted on by all the lighting modules. This other global signal contains instructions to turn off all lighting modules.
- the system is configured to generate three global signals, in which the remote control unit can and is adapted to emit a third global signal providing a blanket instruction receivable and acted on by the receivers of all the lighting modules of the system in the vicinity for powering on the system or turning on illumination of all lighting modules in the system.
- a lighting system in accordance with the present invention is different from systems which for example require the use of two distinct types of radiation or frequencies for communication between the lighting module(s) and the remote control unit.
- the lighting system is also different in that when instructing a lighting module to effect a specific performance, a user is not required to hold onto the remote control unit and aim at a light detector or a small target of the lighting module for directing the signals or commands to the lighting module. Instead, designations of different lighting modules are firstly to be retrieved such that the user can conveniently identify the electronic designation of a particular lighting module or particular lighting modules to which performance is to be effected, and then set the channel of the remote control unit to enter into a relevant channel or pair with the lighting module(s) accordingly.
- Figs. 3a-d illustrate a lighting module 30 of a lighting module according to another embodiment of the present invention.
- the lighting module 30 is different from the lighting module 2 in Figs. 2a-c in that an illuminating portion 32 is provided with an illuminator 34 which can be telescopically extended from or retracted into an illumination cup member 36 thereof, as shown by the arrows in Fig. 3d .

The lighting module and the remote control unit are configured such that wireless infra red signals from the remote control unit are receivable by the lighting module within up to 15 meters of emission.
- Referring to the drawings,
Figs. 2a to 2c show different views of a lighting module of a lighting system according to a first embodiment of the present invention. The lighting module, generally designated 2, includes an illuminatingportion 4. The illuminatingportion 4 is in the form of an inverted cup member 6 in which anilluminator 13 is provided. In this embodiment, theilluminator 13 is a light-emitting diode (LED). The use of LED is advantageous because it can provide a relatively high luminous power and can operate at lower electric current. Further, different colours, intensities or epoxy colours of LEDs can be tailored made to suit a particular purpose. Thelighting module 2 is provided with abase portion 8 from which twolegs portion 4 is attached to thebase portion 8 via thelegs portion 4 is pivotably connected to thelegs lighting module 2. - The
lighting module 2 is provided with a mounting means 14 to which thebase portion 8 is rotatably mounted to the mounting means 14. It can thus be understood that thebase portion 8 is rotatably movable relative to the mounting means 14. - The mounting means 14 is configured such that it can be secured directly on the surface of a ceiling or wall. When mounted on the surface of a ceiling, for example, it is to be understood that the illuminating
portion 4 is movable in two ways. In a first way, the illuminatingportion 4 is movable relative to thebase portion 8 such that lighting from the illuminatingportion 4 is downwardly shining to the floor, as represented by "X" inFig. 2b . The lighting may be downwardly shining or it may be downwardly shining at an angle to the floor or towards an adjacent wall. Alternatively or simultaneously, the illuminatingportion 4 together with thebase portion 8 may be rotatably moved relative to the mounting means 14. - The mounting means 14 can alternatively be mounted indirectly to a ceiling or wall surface via a rail-like member (not shown) attached to the ceiling or wall surface on which the
lighting module 2 can slide. In this alternative, the illuminatingportion 4 can move in a further dimension or in a manner such that lighting can be directed to an adjacent area by sliding the lighting module over. A desired lighting effecting can be achieved by adjusting the configuration and position of thelighting module 2. - The lighting system is configured such that the position of the
lighting module 2 or the illuminatingportion 4 can be adjusted remotely such that adjustment of the position of the illuminatingportion 4 can be effected conveniently when thelighting module 2 is mounted on a ceiling out of normal reach by a user. Specifically, thebase portion 8 is provided with electronics having a receiver for receiving infra red signals emitted from a remote control unit assigned to thelighting system 2.Fig. 1a shows anelectric circuit 16 of the receiver in this embodiment andFig. 1b is a schematic diagram more broadly illustrating thelogistics 18 of the working of the receiver. Thebase portion 8 is also provided with a motor means which acts on instructions from the electronics and can effect movement of the illuminatingportion 4 such that lighting from theilluminator 13 can be directed downwardly or at an angle towards an adjacent wall surface. The motor means can also effect rotation of thelighting module 2 relative to the mounting means 14. The electronics and the parts in thebase portion 8 can also effect other performances including illumination of the LED (to turn on the LED), non-illumination of the LED (to turn off the LED), degree of illumination of the LED (to control the brightness of the LED) and pattern of illumination (to control illumination pattern, eg flashing of lighting from the LED). It is to be understood that these other performances, together with the performances of different movements of the illuminatingportion 4 or thelighting module 2, can create a variety of lighting effects in an environment. It is also to be understood that when the lighting system is provided with a plurality oflighting modules 2, the working of thelighting modules 2 together can create an even greater diversity or versatility of lighting effects. The following examples will explain the lighting system with respect to its hardware and its way of operation which allow setting up of designation(s) of the lighting module(s) 2 by a user. - In this embodiment, when the lighting system is being manufactured it is provided with a default electronic designation in the form of a two-digit numeral although in other embodiments other suitable forms of alphanumerical representations may be used. The default designation in this embodiment is "00" for the
lighting module 2 shown inFigs. 2a-c . When only onelighting module 2 in the lighting system is used a user does not need to change the designation. In such scenario, after the lighting module is mounted to, for example, a ceiling surface, and connected to a power supply, a user can instruct thelighting module 2 to perform a desired performance remotely by using the remote control unit. Specifically, the user merely requires changing the channel of the remote control unit channel "00", thus matching the designation "00" of thelighting module 2. Once the channel has been changed to "00", subsequent signals emitted from a transmitter of the remote control can be received by the receiver and acted on by thelighting module 2. The subsequent signals may contain instructions to, for example, increase the brightness of illumination from the illuminator. - When the
lighting module 2 is connected to a power supply, thedisplay 20 will light up with the visual indication showing its electronic designation. - If a user would like to check the electronic designation of the
lighting module 2, the user is merely required to instruct the remote control unit to send a relevant global signal for checking the electronic designation. This is achieved by pressing a relevant check button on the remote control unit. Once this is done, thelighting module 2 will indicate "00" on the visual display. A "global signal" refers to signals coding blanket instructions which are receivable, acceptable and acted on by all lighting modules within the system. - If there is a plurality of
lighting modules 2 in the vicinity, the visual displays of all thelighting modules 2 will all light up, indicating their own electronic designations, which may be identical or different. It is to be noted that this particular global checking signal is receivable and acted on by all thelighting modules 2 in the vicinity. - Before installation on a ceiling surface, the electronic designation of a
particular lighting module 2 can be changed by firstly connecting the remote control unit with thelighting module 2 with an electrical cable. Once they are connected, the existing electronic designation of thelighting module 2 can be revealed; and if it is to be changed a desired electronic designation can be input directly at the remote control unit and the new electronic designation is then transmitted to store at the memory of thelighting module 2 via the electrical cable. - When there is more than one
lighting module 2, the same electronic designation or different electronic designations may be assigned to themodules 2 in a channel changing exercise for each lighting module accordingly. - After installation of the
lighting module 2 on a ceiling surface, the electronic designation can also be changed remotely or wirelessly. This can be achieved by firstly checking the existing electronic designation assigned thereto as explained above. Then instructions by wireless signals for changing the existing electronic designation to a new electronic designation from the remote control unit are directed to theparticular lighting module 2. This is achieved because the particular wireless signals contain coding with the existing electronic designation such that only the lighting module with this designation will respond to the signals, ie in this case to update its memory and record the new electronic designation. - Once the
lighting module 2 with which a desired performance to be effected is identified, the remote control unit is set at a matching channel. For example, if thelighting module 2 with the electronic designation "01" is to be operated, then the remote control unit is to be set at the matching channel "01" such that operation signals from the remote control unit will contain coding for "01" and only upon receiving the operation signals containing the coding "01" would theparticular lighting module 2 respond. In other words, in this scenario once the remote control unit is set at channel "01" thelighting module 2 with the electronic designation "01" is paired with the remote control unit such that the lighting module is in an operable state. - When there are at least two lighting modules in the lighting system, namely a first lighting module 2A and a second lighting module 2B, and when they are expected to effect the same performance, it is important that they carry the same designation (eg "01") such that they will respond to operation signals with the same performance on instructions from the remote control unit. If not, their designations would have to be brought into consistency. (Changing of the channel can be achieved, as explained above.) In use, the channel of the remote control unit is then set to "01". Then subsequent operation signals containing coding with the electronic designation "01" will be received and acted on by all the lighting modules (ie 2A and 2B) having the electronic designation "01".
- Of course if before installation on a ceiling or wall surface the lighting modules 2A and 2B are expected to effect the same performance, the designations of both the lighting modules 2A and 2B may for example be brought into consistency of eg "01" by connecting the lighting module 2B with the remote control unit with an electrical cable before the lighting module 2B is mounted on a surface. In other words, the designation is changed in a hard-wired manner. Once connected, the designation of the lighting module 2B is changed by the connected remote control unit as explained above. It is to be noted that the remote control unit is battery powered and the power is sufficient to effect the change and record the new designation "01" to the memory unit of the lighting module 2B.
- Alternatively, if both the lighting modules 2A and 2B have already been mounted on a ceiling surface out of reach by a user before the designation "02" of the lighting module 2B is changed to the designation "01", the designation "02" can still be changed wirelessly. This is achieved by firstly sending a remote infra red checking signal from the remote control unit to both the lighting modules 2A and 2B. This checking signal is globally read by the lighting modules. On receipt of this checking signal, visual indications showing the designations "01" and "02" will appear on the display screens of the lighting modules 2A and 2B, respectively. Since the designation "02" of the lighting module 2B is to be changed to "01", the relevant command on the remote control unit is provided, thus sending infra red signal corresponding to the command for changing and recording the designation of the lighting module 2B from "02" to "01" accordingly. Once the designations for the lighting modules 2A and 2B are both brought to "01", both the lighting modules 2A, 2B and the remote control unit can be considered as paired. In this configuration, since both the lighting modules 2A and 2B carry the same designation "01", the lighting modules 2A and 2B are both paired with the remote control unit via the designation (or channel) "01".
- Once the lighting modules 2A and 2B carry the same designations, a user with the remote control unit can control them simultaneously. This is achieved by changing the channel of the remote control unit such that signals emitted therefrom are directed towards both the lighting modules 2A and 2B. On receipt of initial checking signal from the remote control unit, the visual displays of both the lighting modules 2A and 2B will indicate "01" flashing. The user can then set the channel of the remote control to "01" such that subsequent signals from the remote control unit will be recognizable and acted upon by both the lighting modules 2A and 2B.
- If on the other hand different performances of the lighting modules are required, then designations "01" and "02" of the lighting modules need not be changed. Once the lighting modules 2A and 2B are mounted on, for example, a ceiling surface, each lighting module can be adjusted independently. When, for example, a specific performance of only the lighting module 2B is desired then the remote control unit is effected to emit an initial checking signal first. On receipt of the initial checking signal, the visual displays of both the lighting modules 2A and 2B will be flashing with their designations "01" and "02", respectively. Since a specific performance of only the lighting module 2B is desired, the user will, on identifying the designation "02" shown on the visual display, set the channel of the remote control to "02" such that subsequent signals from the remote control unit will be directed to and acted on by the lighting module 2B.
- Then when the lighting module 2B has accomplished the specific performance, the user can change the channel of the remote control unit similarly as explained above in order to effect specific performance of the lighting module 2A.
- It is envisaged that in other embodiments, different number of lighting modules may be provided, with some of the lighting modules sharing the same designations while some do not. For the lighting modules sharing the same designation as indicated by their visual displays, the same performance may be effected simultaneously. For the lighting modules with separate or unique designations, they may be controlled independently. It can be appreciated that when there are a plurality of lighting modules they are still be controlled in a similar manner. An embodiment of the lighting system according to the present invention is configured such that another global signal may be emitted by the remote control unit, and receivable and acted on by all the lighting modules. This other global signal contains instructions to turn off all lighting modules. It is to be noted that it will be within the grasp of a skilled person in the art to understand and arrive at the construction of the electronics required in this invention. It is thus to be understood that in this embodiment, there are two global signals, one for sending checking instructions, and the other for turning off the system, both are directed to all lighting modules. In a different embodiment of a lighting system according to the present invention, the system is configured to generate three global signals, in which the remote control unit can and is adapted to emit a third global signal providing a blanket instruction receivable and acted on by the receivers of all the lighting modules of the system in the vicinity for powering on the system or turning on illumination of all lighting modules in the system.
- From the above, it is to be understood that a lighting system in accordance with the present invention is different from systems which for example require the use of two distinct types of radiation or frequencies for communication between the lighting module(s) and the remote control unit. The lighting system is also different in that when instructing a lighting module to effect a specific performance, a user is not required to hold onto the remote control unit and aim at a light detector or a small target of the lighting module for directing the signals or commands to the lighting module. Instead, designations of different lighting modules are firstly to be retrieved such that the user can conveniently identify the electronic designation of a particular lighting module or particular lighting modules to which performance is to be effected, and then set the channel of the remote control unit to enter into a relevant channel or pair with the lighting module(s) accordingly.
