## Abstract

A light-emitting unit capable of setting an address easily and reliably and checking the result of address setting. The light-emitting unit, such as an LED unit that constructs the unit of light emission of a display unit or the unit of light emission of an ornamental display, includes an infrared receiving element that receives data including an address transmitted by infrared light; an address storage section that stores the address; and a controller that recognizes an address from the data and stores the address in the address storage section. Preferably, the controller stores the light-emission patterns of a display LED for a normal address setting and an erroneous address setting, wherein when normal setting is recognized, the display LED emits light in a normal-setting emission pattern, and when an error is recognized, the display LED emits light in a error-setting emission pattern.

## Claims

### Claim 1

A light-emitting unit constructing the unit of light emission of a display unit or the unit of light emission of an ornamental display, comprising:
an infrared receiving element that receives data including an address transmitted by infrared light;
an address storage section that stores the address; and
a controller that recognizes an address from the data and stores the address in the address storage section,
wherein the data containing the address is data in a specific format whose correctness can be verified and the controller verifies the correctness of the format of the data,
wherein only when the correctness of the format is confirmed, the address is stored in the address storage section,
wherein the controller stores a predetermined time longer than the quiescent time of a display control signal of a display light emitter, and determines whether the quiescent mode is continued for more than the predetermined time period or over the predetermined time period immediately before the recognition of the data input, and
wherein only when the quiescent mode is continued for more than the predetermined time period or over the predetermined time period, the controller recognizes the address from the data.

### Claim 2 (depends on 1)

The light-emitting unit according to claim 1,
wherein the controller determines whether the quiescent mode is continued during a necessary time from the recognition of the input of the data to the completion of the extraction of the address from the data, or from the recognition of the input of the data to the completion of the verification of the format of the data, and
wherein only when the quiescent mode is continued, the controller stores the address in the address storage section.

### Claim 3 (depends on 2)

The light-emitting unit according to claim 2,
wherein the controller stores the light-emission patterns of the display light emitter for normal address setting and erroneous address setting, and
wherein when normal a setting is recognized, the display light emitter is lit up in a normal-setting emission pattern, and when an error is recognized, the display light emitter is lit up in a error-setting emission pattern.

### Claim 4 (depends on 1)

The light-emitting unit according to claim 1,
wherein the controller stores the light-emission patterns of the display light emitter for normal address setting and erroneous address setting, and
wherein when normal a setting is recognized, the display light emitter is lit up in a normal-setting emission pattern, and when an error is recognized, the display light emitter is lit up in a error-setting emission pattern.

### Claim 5

A light-emitting unit, constructing the unit of light emission of a display unit or the unit of light emission of an ornamental display, comprising:
an infrared receiving element that receives data including an address transmitted by infrared light;
an address storage section that stores the address; and
a controller that recognizes an address from the data and stores the address in the address storage section,
wherein the data containing the address is data in a specific format whose correctness can be verified and the controller verifies the correctness of the format of the data,
wherein only when the correctness of the format is confirmed, the address is stored in the address storage section,
wherein the controller determines whether the quiescent mode is continued during a necessary time from the recognition of the input of the data to the completion of the extraction of the address from the data, or from the recognition of the input of the data to the completion of the verification of the format of the data, and
wherein only when the quiescent mode is continued, the controller stores the address in the address storage section.

### Claim 6 (depends on 5)

The light-emitting unit according to claim 5,
wherein the controller stores the light-emission patterns of the display light emitter for normal address setting and erroneous address setting, and
wherein when normal a setting is recognized, the display light emitter is lit up in a normal-setting emission pattern, and when an error is recognized, the display light emitter is lit up in a error-setting emission pattern.
