い。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an indoor lighting device. 2. Description of the Related Art In a conventional indoor lighting fixture, a small round light bulb or the like is mainly provided as a nightlight on the lower surface side of the fixture. [0003] Since the nightlight is provided on the lower surface side of the fixture, the eyes may be too bright if the eyes become accustomed to darkness. When a small round light bulb is installed on the ceiling side to reduce the brightness, dust collects around the light bulb, so it is necessary to take measures such as attaching a dust cover so as not to cause a fire, There are disadvantages, such as the difficulty in replacing the bulb because the bulb is on the ceiling behind the fixture. If the indoor lighting fixture is of a ceiling-mounted type, the main light source in the fixture (for example, a ring-shaped fluorescent lamp) when the nightlight is on
And some other parts cause strange shadows to be reflected on the translucent cover on the lower surface side. In addition, when the number of main light sources is large, a space for providing a nightlight is limited, and it is troublesome to consider a place where the main light source is provided. In the present invention, the light of the nightlight is softened without directly entering the eyes, and it is reduced that it is too bright,
An object of the present invention is to provide an indoor lighting device which does not cause a fire or the like even if dust accumulates, reduces the trouble of replacing a main light source, and is free from a fear of a shadow caused by a nightlight. [0004] An indoor lighting fixture of the present invention includes a backbone facing a ceiling surface. A circuit board for mounting each circuit component, the circuit board being disposed on a lower surface side of the backbone; A light emitting diode mounted on the upper surface side of the circuit board and wired to the circuit board; The light emitting diode is in a posture for projecting upward light. The upward light of the light emitting diode is directed toward the ceiling without being blocked by the backbone. An embodiment of the present invention will be described with reference to FIGS. 1 and 2. The indoor lighting fixture according to the present invention includes a backbone 1 facing a ceiling surface. A circuit board 2 on which a circuit component is mounted and which is arranged on the lower surface side of the backbone is provided. The light-emitting diode 4 is mounted on the upper surface of the circuit board 2 and wired to the circuit board 2. The light emitting diode 4 is in a posture for projecting upward light. The upward light of the light emitting diode 4 travels toward the ceiling without being blocked by the backbone 1. Supplement the explanation. An insulating case 3 incorporating a circuit board 2 is attached to the backbone 1. When the circuit board 3 incorporated in the insulating case 2 is attached to the backbone 1, a part of the light emitting diode 4 mounted on the upper surface side of the circuit board 2 is exposed upward from the aperture 5 provided in the backbone 1. Even if the light emitting diode 4 is arranged at a lower position than the current state and the light is radiated through the light transmitting hole corresponding to 5, the same effect is obtained in the upward light transmission. FIG. 2 shows details of the aperture 5 for projecting a part of the light emitting diode 4 upward. When the circuit board 3 incorporated in the insulating case 2 is attached to the backbone 1, the position of the light emitting diode 4 is easily determined. Paste around 5.
The illustrated indoor lighting fixture is a ceiling-mounted fixture (ceiling light), but the same effect can also be obtained with a ceiling suspended fixture. According to the present embodiment, the following advantages are obtained. The light of the light emitting diode (nightlight) 4 does not directly enter the eyes and becomes soft, so that it is reduced that the light is too bright. Since the temperature of the light emitting diode 4 is low, even if dust accumulates, it does not cause a fire or the like, and the trouble of replacing the lamp is reduced. Nightlight 4
No worries about strange shadows on the internal parts of the instrument. There is no worry that the fluorescent lamp 7 or the like is in the way and it is difficult to arrange the nightlight 4. Since it is mounted on the circuit board 3, components such as a nightlight socket can be reduced. According to the present invention, the light of the nightlight is soft and does not directly enter the eyes, so that the light is not too bright. Even if dust accumulates, it does not cause a fire, etc. The trouble of replacement is also reduced. Also, there is no worry about shadows caused by the nightlight.
