Description

[0001] The present invention relates to a LED light signal device,

[0001] The present invention relates to a control unit and a display unit separate railway LED signaling apparatus, and more particularly, in a display unit, an LED is divided into a first LED and a second LED, The control part can be replaced on the ground and the control part can be replaced with the same control part because they can be compatible with each other. The present invention relates to a display separated railway LED signaling device.

And when the main power is not supplied and the signal can not be turned on, the red LED is lit by using the power supply module battery provided in the control unit.

 Generally, a luminaire using an LED has a drive control unit for driving the LED, and is composed of a light emitting unit (display unit) emitting light by the LED. When the lifetime of the LED is about 5 to 6 years, the lifetime of the LED drive control unit that supplies the power to turn on the LED is far less than that. Therefore, there is a problem in that the lifetime of the LED control unit for supplying the normal or lighting power is shortened, so that the LED is not turned on and the service life is shortened. In addition, when the maintenance is difficult due to the shortened life span, the maintenance cycle is increased and the maintenance cost is increased.

The LED signal applied to the railway signal is integrated by connecting the control part and the display part to the connector. However, the LED which is the display element may be burned out due to excessive vibration or lightning when passing through the train, or terminal relaxation may occur. In the event of a fault in the control unit, which has a higher frequency of failure than the display unit comprising LEDs, the repairer rises to the level of the signaling unit and repair is difficult. Such maintenance is a great burden on the maintenance worker working in a high place, and there is always a risk of slipping due to snow. In addition, since the control unit and the display unit are integrally formed, the entire control unit and the display unit are replaced even in the event of a failure of the control unit, so that waste of resources is inconvenient and the maintenance cost is greatly increased.

Therefore, in case of failure of control unit frequent faults frequently compared to the display unit, the risk of the maintenance worker is lowered by safely working on the ground without raising the high position of the signaling unit for maintenance. In case of failure of the display unit or control unit, And to reduce the loss of resources.

In order to ensure the security and safety of the railway signaling system, the LEDs of the display unit are separated into the first and second systems, normally used as the first system, and when the first system fails, the system is automatically switched to the second system, It is necessary to have a product that can improve the efficiency of maintenance and prevent a safety accident by manually switching the maintenance person from the first stage to the second stage.

2) When the LED is off, the fuse of the power supply is checked. In case of using the group type relay, the fuse capacity is checked because a slightly higher current than the bulb occurs at the moment of lighting. In case of operation of internal reset switch, temporary lighting is caused by lightning or instantaneous power shock. In case of LED control module burnout check, it is to check for burnout due to severe leakage or direct lightning.

3) In case of checking the setting of the change-over switch of the LED control module in the abnormal state, it is preferable to set the change-over switch No. 1 according to the distinction between the insertion-type relay and the group-type relay. In the case of a check of a unit or relay group, check the operation status of devices forming the present condition. For example, in the case of the group check of the light-off detection relay, the abnormal light-on state and the normal light state are classified and stored according to the distinction between the insertion-type relay and the group-type relay.
