Problems solved by technology

Regarding such an operation, it is not described in the above-mentioned patent document 1, and it cannot be handled as it is.
[0007] For example, if there are multiple brightness sensors in the same control group, if the master unit collects the information of each brightness sensor and performs processing such as averaging, if the appliance itself and the master unit do not know the individual brightness sensors in advance, number, and which appliance has a brightness sensor, it is difficult to implement the desired control action
[0008] In addition, when averaging the information of a plurality of brightness sensors in each appliance, if the appliance itself does not know in advance how many brightness sensors are currently connected, it is difficult to implement the desired control operation.
[0009] If the above-mentioned problem is fixed in the sensor connected to the lighting fixture, it can be dealt with by setting it in the lighting fixture in advance, but in the case where the sensor can be replaced freely, this mechanism cannot be used, and its existence cannot be dynamically judged in the system. The question of which sensor is connected to the lighting fixture

specific Embodiment approach

[0042] The present invention provides a lighting system that can dynamically remove and replace sensors corresponding to changes in the control area. The lighting system of the present invention is composed of a plurality of lighting fixtures in the embodiments described later.

no. 1 Embodiment approach

[0044]figure 1 It is a figure for demonstrating the schematic structure of the lighting fixture 12 which concerns on 1st Embodiment of this invention. The lighting fixture 12 is composed of a lamp 16 , a lighting circuit (inverter) 15 , a control block 13 for controlling it, and a sensor block 14 that transmits information detected from a control area to the control block 13 . Moreover, the commercial AC power supply 11 is connected to the lighting fixture 12, for example.

[0045] The control block 13 has a microcomputer as a control mechanism 17, a memory as a storage mechanism 18, and a communication interface 19 with the sensor block 14. The control mechanism 17 controls the lighting circuit 15 using sensor information such as sensor type information and sensor detection information. The storage unit 18 stores sensor type information and the like.

[0046] In the sensor block 14, there are: a sensor element 22, such as a light receiving element that detects brightness and...

no. 2 Embodiment approach

[0060] The lighting fixture 12 according to the second embodiment of the present invention has the same configuration as that of the first embodiment, and the method of transmitting the sensor type from the sensor block 14 is different. Figure 6 The operation sequence of the method of transmitting the sensor type from the sensor block 14 according to the second embodiment of the present invention is shown.

[0061] Since the sensor block 14 receives power supply while being connected to the control block 13 (step S21 ), the microcomputer 35 starts up (step S22 ). As shown in steps S23 and S24, when the sensor block 14 transmits the sensor detection information to the control block 13, it always transmits together with the sensor type information. The sensor block 14 transmits a sensor detection information signal (person detection information, brightness level, etc.) periodically (for example, period t1 ).

[0062] The control block 13 periodically reads the received sensor ...

Abstract

The present invention provides a cheap lighting control system for corresponding to changes of control region and a lighting system capable of separating or replacing sensors dynamically. Sensor block (14) is prestored with information of providing sensor. Micro-computer starts when the sensor block (14) connecting to control block (13) and receiving power supply. Micro-computer of the sensor block (14) starts, then first sending own sensor class to the control block (13). Micro-computer of the control block (13) stores the sensor class, which will be used in lighting circuit (15) in necessary. The sensor block (14) is provided with separation notification switch (23), and the sensor block (14) sends separation information for separating to the control block (13) in case of the sensor block (14) being removed.

Description

technical field [0001] The present invention relates to a lighting system for controlling the brightness of a space, and in particular to a lighting fixture in which a control area can be easily changed and an internal sensor can be separated and replaced. Background technique [0002] In the lighting space, in the case of independently operating control for each area, for example, for a system that performs the same motion control when a person is detected, in order to also respond to changes in the area, by pre-setting By disposing the same sensor on the appliance, it is possible to respond to changes in the control area. [0003] In the mechanism disclosed in Patent Document 1, the above-mentioned problem can be solved by equipping a function extension terminal on the side of the lighting fixture and combining it with other function plug-ins that have various functions having the same structure as the extension terminal. , such as a human detection function, or a functio...
