LIGHTING DEVICE USING COMPOSITE CABLE IN WHICH OPTICAL FIBER CABLE IS INCLUDED

摘要

The present invention relates to a lighting device using a composite cable in which an optical fiber cable is included, comprising: a dimmer (A) which generates light; an optical fiber cable (K) which delivers and irradiates the light generated from the dimmer (A) by being connected with the dimmer (A), and includes a multi-core optical fiber (L) having a power line (a) and a control line (b); and a lighting appliance (R) which is coupled with a fore-end of the optical fiber cable (K) that irradiates the light, wherein: the lighting appliance (R) constitutes a housing (50); a holder base (51) is inserted into and coupled with an inner sidewall of the housing (50), and an optical fiber holder (52) is inserted into and coupled with a fore-end of the multi-core optical fiber (L); the fore-end of the multi-core optical fiber (L) is fixed as a holder body (53) in the central part of the holder base (51), wherein said fore-end is fixed by coupling bolts (54) as fixing means between the holder base (51) and the holder body (53); a transparent protection glass (55) is coupled on the front of the holder body (53) and a step (56) is formed on a front fore-end of the housing (50) whereby a transparent tempered glass (57) and a protection cover (58) are coupled, and sealing O-rings (59) are coupled between the tempered glass (57) and the step (56) of the housing (50); and an insect repelling device (Q) is provided within the lighting appliance (R) by a fixing bracket (g), the insect repelling device (Q) is connected with the power line (a), and further, a detection sensor (S) is selectively provided within the lighting appliance (R) by the fixing bracket (g) when necessary, and then the detection sensor (S) is connected with the control line (b). Consequently, the invention shows the following advantages: relative to the light irradiated through the optical fiber, the dimmer blocks the infrared rays to prevent any heat whereby any dew condensation, that is, dew formed within the lighting appliance, can be prevented; since the UV rays and the infrared rays are not generated from the irradiated light, there is no harm to a human body and plants; since only the light generated from the dimmer is delivered through the optical fiber without electricity, no electricity flows into the optical fiber cable and the lighting appliance, thereby avoiding a short circuit even though the lighting appliance is submerged in water or moisture permeates into the lighting appliance; since the insect repelling device is configured within the lighting appliance, electric fields and ultrasonic waves are generated to repel flying insects such as mosquitoes, flies, rats, cockroaches and the like, harmful insects, and worms or the like; and when the detection sensor is equipped within the lighting appliance, a signal sensed from the detection sensor is connected to the dimmer, thereby performing brightness adjustment, power on-off, and lighting design functions or the like.
