As shown in Figures 1 to 3, the indoor lighting device having the light emitting diode of the present invention as an emergency lighting source is largely an opening through which the fluorescent lamp 30 is exposed in the center of the bottom (hereinafter referred to as a "fluorescent lamp exposure") The housing 10 may be formed of a box-shaped housing 10 in which 12 is widely located. At least one fluorescent lamp 30 is provided in the housing 10, and six are provided in this embodiment.

On the other hand, a plurality of light emitting diodes (hereinafter referred to as 'LEDs') 50 in the interior of the edge portion 14 forming the edge of the housing 10, for example, the fluorescent lamp exposed portion 12, LED support plate It is arrange | positioned while being supported by 16, The LED exposure hole 14a for exposing the light from the LED 50 is formed in the surface of the edge part 14. As shown in FIG. 1 shows an example in which between 30 and 40 LEDs 50 are disposed on the left side and the right side of the edge portion 14 so as to function as an emergency lighting source, the shape of the housing 10. And according to the size may be different placement position and number of the LED (50).

Regarding the emission color of the LED 50, in recent years, a multi-color LED has been developed that has a red, green, or blue LED in one case together to produce a desired color by combining the driving properly. In the design, red, green, and blue monochromatic LEDs may be used, or multicolor LEDs may be used as necessary. For reference, when red and green are mixed, they become yellow, and when red, green and blue are mixed, they become white.

4 is an electrical block diagram of an emergency lighting source in an indoor lighting device having a light emitting diode of the present invention as an emergency lighting source, and may be configured in parallel with an electrical configuration of a fluorescent lamp, and preferably, a housing ( 10) It can be installed inside. In addition, the circuit configuration for driving the fluorescent lamp 30 is already well known in the art and is omitted. As shown in Figure 4, the electrical configuration for the emergency lighting source of the present invention is a DC voltage generator 110 for generating a DC voltage of a predetermined size, for example 12 [V] by reducing and rectifying the commercial AC power supply ), The battery 140, which is used as an emergency power source, the voltage of the DC voltage generator 110 by checking the voltage of the power failure detector 120, DC voltage generator 110 to detect whether there is a power outage Charge circuit unit 130 to charge 140, prevent overcharging, and alarm other low voltage of the battery 140, LED 50 as an emergency light source, LED driver for driving the LED 50 170, a DC voltage from the DC voltage generator 110 and a DC voltage from the battery 140 may be provided from the switching unit 160 and the power failure detecting unit 120 to alternatively provide the LED driver 170. Whether the AC power is normally supplied by the detection signal, i.e. power failure In the case of power failure, the control unit 150 switches the switching unit 160 from the DC voltage generating unit 110 to the battery 140 and issues an operation command to the LED driver 170. Can be.

In the above-described configuration, the switching unit 160 may be an electromechanical switch having a contact such as a relay or a solid state switch such as a transistor. In the drawing, reference numeral 180 denotes a power switch for forcibly turning on or off the LED 50 by the supply voltage of the DC voltage generator 110 in the state where the commercial AC power is normally supplied. In the case where the LED 50 is turned on or off, the LED 50 may function as an auxiliary illumination source. Of course, in this case, the LED 50 may be turned on / off in conjunction with the fluorescent lamp 30 or may be turned on or off independently of the fluorescent lamp 30.

In the above-described configuration, in the state where the commercial AC power is supplied, a detection signal indicating that the power failure detection unit 120 is normal is output to the control unit 150. Accordingly, the control unit 150 generates the DC voltage in the switching unit 160. The controller 110 is switched to the unit 110 side, and further, the LED driver 170 is turned on to turn on the LED 50. Of course, if the power switch 180 is turned off in this state, the lighting is not made.

On the other hand, when the supply of commercial AC power is cut off, that is, when a power failure occurs, the power failure detecting unit 120 detects this and notifies the control unit 150. The control unit 150 subsequently switches the switching unit 160 to the battery 140. Switch to the side. At the same time, the LED 50 is turned on by outputting a control signal to the LED driver 170, whereby the resident can perform necessary activities.

The indoor lighting device having the light emitting diode of the present invention as an emergency lighting source can be implemented without various modifications within the range allowed by the technical idea of the present invention without being limited to the above-described embodiment. For example, in the above-described embodiment, the control unit 150 has been described as controlling the switching operation of the switching unit 160, but unlike this, the power failure detecting unit 110 directly deletes the switching unit in a state where the control unit 150 is deleted. In order to control the 160 and the power is turned on, the LED driver 170 may simplify the configuration by lighting the LED 50 unconditionally. For example, the power failure detecting unit 120 is configured as a relay coil and the switching unit 160 is configured as a contact switching operation by the relay coil, and the contact generates an DC voltage by an electromagnetic force when the relay coil is excited. The switching unit 110 may be switched to the battery 140 side by a spring force (not shown).
