Description

The present invention relates to a light emitting device such as an LED lighting lamp that is attached to a lighting device (lighting fixture) installed on a ceiling or the like in a room and emits light, and a light emitting life data management system that manages data related to the light emitting life of the light emitting device.

Lighting devices (lighting fixtures) are installed in the rooms of buildings such as companies and homes. A light emitting device such as an LED lighting lamp, a fluorescent lamp, or an incandescent lamp is attached to this lighting device. A light emitting device attached to such a lighting device usually has a finite period in which it can emit light. When this period elapses, the light emission life at which light cannot be emitted is reached. Therefore, the user or manager of the light emitting device determines the time when the light emitting device of the currently used light emitting device has reached the end of its light emitting life, prepares a new light emitting device based on the judgment, and uses the currently used light emitting device. When the light emission life has expired, it is replaced with a new light emitting device prepared.

However, in particular, LED lighting and the like have a longer light emitting period than conventional fluorescent lamps and the like, and it is not easy to determine the end of the light emitting life by visually observing the appearance. Therefore, it is difficult to accurately determine the time when the emission life is reached. Therefore, if the light emitting device suddenly reaches the end of its light emitting life when a new replacement light emitting device is not prepared, the lighting device may be temporarily disabled. This is not preferable for the user of the lighting device not only from the viewpoint of convenience of life but also from the viewpoint of safety.

Further, in recent years, a business in which a business operator who rents (rents) a light emitting device rents the light emitting device to a business partner's company or a home has been carried out. Even in such a light-emitting device rental business form, the time when the light-emitting life of the rented light-emitting device will reach is predicted in advance, and the light-emitting device rented before the predicted time is replaced with a new light-emitting device. Is required. At present, a business operator who rents a light emitting device predicts when the light emitting device will reach the end of its light emitting life based on the start date and performance of the rented light emitting device (see Patent Document 1).

Therefore, the rental company of the light emitting device is required to accurately predict the time when the light emitting device of the rented light emitting device will reach the end of its light emitting life based on the actual usage situation in the company or home. However, since there are various ways of using the light emitting device at the rental destination, it cannot be denied that the light emitting life of the light emitting device may arrive before the time predicted in advance depending on the usage situation of the light emitting device. The reality is that accurate predictions are extremely difficult.

On the other hand, as a method for predicting the time when the light emitting life is reached, Patent Document 2 describes the time when the light emitting device installed in the tunnel is inspected and the light emitting device reaches the end of the light emitting life based on the information obtained by this inspection. It is stated to predict. However, the method described in Patent Document 2 has a problem that it takes time and cost because the manager of the light emitting device goes to the place where the light emitting device is installed and makes a judgment about the light emitting life. In particular, in the business of renting light emitting devices to companies and homes, unlike the case where many light emitting devices are collectively installed in a tunnel as described in Patent Document 2, it is used in many companies and home buildings scattered over a wide area. Since a large number of light emitting devices are attached to the installed lighting devices, it is not realistic to go to all the installation locations of these light emitting devices and perform inspections because it requires a great deal of labor and cost.

By being configured to transmit the data signal received by the data receiving unit, the light emitting device can transmit the data signal including the data signal related to the light emitting life of the other light emitting device to the outside. Therefore, if a plurality of light emitting devices having the above configuration are installed, it is possible to sequentially transfer data related to the light emitting life of a large number of light emitting devices via the light emitting device and collect the data in a relay device or the like. Therefore, even if a large number of light emitting devices are installed in lighting devices installed in a large number of companies and home buildings scattered over a wide area, it is easy to manage data on the light emitting life of these many light emitting devices with a small capital investment.

Since it is configured to receive the data signal S related to the light emitting life of 1H), the data signal S related to the light emitting life of a large number of light emitting devices 1 (1A to 1H) is sequentially transferred to the data receiving device 113. It becomes possible to aggregate and manage data relating to the light emission life of a plurality (many) light emitting devices 1 (1A to 1H) scattered in the area to which the light emitting life data management system 300 is applied. Further, since the data related to the light emitting life can be managed regardless of the number of the light emitting devices 1 included in the light emitting life data management system 300, it can be used for lighting devices installed in many offices and home buildings scattered over a wide area. Even when a large number of light emitting devices 1 are attached, the system can collectively manage the light emitting life of a large number of light emitting devices 1. Therefore, it is possible to efficiently manage the data regarding the light emitting life of the light emitting device 1.
