Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an LED lighting device,

[0001] The present invention relates to an LED illumination lamp having a check display lamp, and more particularly, to an LED illumination lamp having a check indicator lamp for notifying a failure of a converter or an LED lamp, The operator entering the inside of the ceiling panel in which the LED lights are installed can easily recognize by the naked eye which of the plurality of LED lighting lamps has a problem with the converter or the LED lamp, And an LED illumination lamp provided with a check display lamp so as to be improved.

Conventional light sources such as incandescent bulbs or fluorescent lamps are widely used in homes, offices, and the like. Such incandescent bulbs or fluorescent lamps are high in power consumption, wasting resources, adversely affecting environmental protection, There is a problem that the electrical resistance of the filament is high and the environmental temperature is increased and the service life of the lamp is short.

Accordingly, lighting lamps using light emitting diodes (hereinafter referred to as "LEDs") that can maximize lighting effects with a variety of illumination lights and high visibility can be developed and are widely used because of their low power consumption and miniaturization in recent years It is true.

The LED is a photoelectric conversion semiconductor device having a structure in which an N-type semiconductor crystal in which a plurality of carriers are electrons and a P-type semiconductor crystal in which a plurality of carriers are holes are bonded to each other. Refers to a semiconductor light emitting device using spontaneous emission light generated when electrons and holes are recombined.

Because of this high efficiency of photoelectric conversion efficiency (Efficiency, lumen / watt), the power consumption is low compared with incandescent bulbs and fluorescent lamps, and the preheating time is unnecessary.

In addition, since LED has no gas or filament, it is strong against shock, safe, adopts a stable DC lighting method, and has power consumption as well as pulse operation and fatigue of optic nerve can be reduced. This semi-permanent lighting effect of various colors can be achieved and miniaturization is possible.

Most of the lighting lamps using such LEDs are provided with a converter, which is a power supply module. The converter itself causes heat generation, is vulnerable to heat, and has a short life span.

For example, the lifetime of the LED chip constituting the LED light is approximately 50,000 hours, whereas the life of the converter is only 15,000 hours.

Thus, despite the lifetime of the LED chip, there is a disadvantage that if the converter reaches its end of life, the lighting lamp or the entire lighting bulb must be replaced. In fact, a power supply module ('a component included in a converter') having an electrolytic capacitor having a short degradation characteristic, that is, a power supply module, is often caused to fail earlier than the LED chip .

Meanwhile, when a plurality of LED illumination lamps are installed on a ceiling of a building and a converter installed in any one of the LED illumination lamps is not normally operated, The bottom cover should be opened and the converter replaced.

However, since the conventional LED illumination lamp does not have a separate indicator lamp for indicating the failure state of the converter or the LED lamp when the converter or the LED lamp fails or does not operate normally, even if the operator enters the inside of the darkened ceiling panel, There is a problem that it is not possible to easily identify which converter or LED lamp of the LED illumination lamp is faulty, so that the repairing and replacement workability is very poor.

On the other hand, as a prior art, Korean Registered Patent Publication No. 10-1005199 (name: LED protection device in case of an abnormal state of an LED load of an LED lighting apparatus) has been proposed.

The prior art includes a sensing resistor connected in series to the LED module to sense an open or short state of an LED constituting the LED module; A load abnormality detecting means for determining a short or open state of an LED constituting the LED module using the voltage value detected by the sensing resistor and outputting a predetermined compensation signal according to the determination information; A reference constant current value that allows the constant current to be constantly supplied to the LED lamp by sensing the total current applied to the LED lamp is supplied to the control unit and the reference constant current value supplied to the control unit by the compensation signal output from the load abnormal detection unit is decreased And a reference constant current setting unit for protecting the other normal LEDs constituting the LED lamp from the overcurrent when the LEDs are in an abnormal state. Thus, in the LED lamp in which a plurality of LEDs are installed in series and in parallel, ) To detect when a status occurs and reduce or cut off the constant current value supplied to the LED lamp so that it can protect the LED from the fire caused by overheating or other normal LED damage due to the overcurrent.

However, in the above-described prior art, when the converter or the LED lamp does not operate normally, the operator can not visually confirm the converter or LED lamp, so that the workability of repairing and replacing the converter and the LED lamp is greatly reduced.
