Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a small light bulb and a rectifying diode mounted in a holder made of an insulating material, and is capable of lighting a light bulb only when a current flows in a predetermined direction or an LED (light emitting diode) lamp. The present invention relates to a lamp device and a lighting device that are integrally equipped with a current limiting resistor.

[0002]

2. Description of the Related Art In a light bulb, a filament coil in which a tungsten wire is wound emits light when a current is passed through it. In a lighting device using a light bulb, the light bulb does not move in any direction. It lights up and has no particular polarity.

However, if the light bulbs are turned on regardless of the current flowing in them, all the light bulbs are turned on or off at the same time when a plurality of light bulbs are connected between two conductors or conductors. Therefore, the light bulb was divided into two sets, and each set could not be turned on and off.
And in this way, two sets of light bulbs are turned on independently.
At least three conductors and conductors were required to turn off the light.

Therefore, a lamp device in which a diode is connected in series with a light bulb and these are housed in the same holder is considered. If a plurality of lamp devices having such a configuration are connected and attached to a strip-shaped electric wire having two conducting wires, for example, the polarities of the diodes are alternately changed, and the polarities of the power supplies are alternately changed to flow through the first set. The light bulbs of the group and the second set group can be turned on alternately.

However, in this lamp device, the bulb of the light bulb is elastically held in the opening of the holder, the diode is housed in the holder or in the bottom of the holder, and the lead wires of the diodes are internally connected by means such as soldering. However, this lamp device is inserted and mounted in a socket provided in the strip-shaped electric wire.

In the holder of this lamp device, when replacing the light bulb by changing the output of the light bulb, it is necessary to replace each holder without removing the individual parts easily. Some of its outer shapes are symmetrical,
There may be an indication of the polarity of the diode on the terminal, but you can attach and connect with either polarity by rotating the holder around the band-shaped electric wire. For this reason, the lamp device is often attached with the wrong polarity, and there is a problem that the light bulb is not turned on at a predetermined time, and illumination or display is not performed. Further, since the light bulb and the diode are connected in series by a lead wire or the like, the total length of the holder becomes long, and it may not be possible to deal with the case where a short holder is required.

Also, various LED (light emitting diode) lamps in which an envelope portion (corresponding to a bulb) in which a light emitting portion is buried are made of a transparent synthetic resin have been put to practical use. A limiting resistor must be connected in series, and this connection also employs means such as soldering. Therefore, there is a problem that the work is troublesome when mounting or connecting the lamp or the resistor.

[0008]

DISCLOSURE OF THE INVENTION The present invention eliminates the above-mentioned problems, and can easily attach and replace a light bulb or an LED (light emitting diode), can be mounted without any polarity error, and can be miniaturized.
