DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light bulb used as a light source for, for example, a vehicular lamp, a traffic signal lamp, and the like. The present invention relates to a light bulb configured to be easily operated.

[0002]

2. Description of the Related Art This type of conventional socket-integrated light bulb 90 is disclosed.
FIG. 4 shows an example of the configuration of (1). The valve section 91 and the socket section 92 are integrated by a holder section 93. A terminal 94 connected to the lead wire of the valve portion 91 is accommodated in the socket portion 92, and is filled with a sealing material 95 such as a resin to form an airtight structure. Further, a seal packing 96 is provided at a portion where the socket portion 92 is inserted into the lamp 80.

FIG. 5 shows a state in which the socket-integrated light bulb 90 constructed as described above is mounted in the light-bulb mounting hole 81 of the lamp 80. The socket-integrated light bulb 90 is formed by the seal material 95 and the seal packing 96. Since the airtightness is maintained between the lamp 90 and the lamp 80, the internal pressure of the lamp 80 changes due to a change in the internal temperature caused by, for example, lighting and extinguishing of the socket-integrated bulb 90. .

Therefore, in a lamp 80 employing a conventional socket-integrated light bulb 90 as a light source, for example, a vehicle lamp, a traffic signal lamp, etc., a vent hole 82 is provided to alleviate a change in internal pressure. The inside and outside air are circulated to keep the internal pressure constant.

[0005]

However, in the lamp 80 employing the above-described conventional socket-integrated light bulb 90, the outside air flows through the ventilation hole 82, and therefore, especially when suction is performed. Dust and the like contained in the outside air are also sucked at the same time, and the dust and the like are accumulated inside as the use time elapses, causing problems such as a decrease in illuminance.

In order to solve this problem, at the time of periodic inspection, the socket-integrated light bulb 90 is removed, the hand is put into the lamp 80 through the light bulb mounting hole 81, and the inside is cleaned. In this case, there is a high possibility that the reflection surface 83 will be damaged, and as a result, there is a problem that the useful life of the lamp 80 as a whole is impaired.

In order to prevent the above-mentioned dust from being sucked, a device in which a dust filter 84 is incorporated in the ventilation hole 82 has been proposed. In this case, the dust filter 84 is added to the dust filter 84 over time. Accumulates, causing a so-called clogged state, resulting in a problem that the air permeability is lost and the ability to alleviate a change in the internal pressure is reduced, and solving these points is an issue.

[0008]

According to the present invention, as a specific means for solving the above-mentioned conventional problems, there is provided a socket-integrated bulb comprising a bulb portion and a socket portion, wherein one of the socket portions is a lamp. The problem is solved by providing a socket-integrated light bulb characterized in that an air passage opening to the inside and the other opening to the outside of the lamp is provided, and a dustproof filter is provided in the air passage. Is what you do.

[0009]

Next, the present invention will be described in detail based on an embodiment shown in the drawings. In FIG. 1, a lamp indicated by reference numeral 1 is a socket-integrated bulb (hereinafter abbreviated as “integrated bulb 1”) according to the present invention.
It is the same as the conventional example in that the socket and the socket 3 are integrated by the holder 4.

Here, in the present invention, as shown in FIG. 2, the socket portion 3 extends between the inner side and the outer side of the lamp 10 in a state where the socket portion 3 is attached to the bulb mounting portion 11 of the lamp 10. And one of them is a lamp 10
The ventilation path 5 is provided such that it is opened to the inside and the other is opened to the outside of the lamp 10.

In addition, in the present invention, the air passage 5
A dust filter 6 is provided therein. In addition, a seal packing 3a is provided at a portion where the socket portion 3 is inserted into the light bulb mounting portion 11, and a sealing material 7 is filled at a connection portion of the terminal 3b with the external wiring. Compatibility with body lamps is maintained.

At this time, the other one of the openings 5a which is open to the outside of the lamp 10 in the ventilation path 5 has a possibility of sucking water droplets together with air, for example, at the time of rainfall. Since the entire socket portion 3 is covered by a housing (not shown) or the like, water droplets and the like do not directly reach the opening 5a. Therefore, the eaves portion 5b for preventing water droplets from dropping is provided. Is provided.

Next, the operation and effect of the integrated lamp 1 of the present invention having the above-described configuration will be described. First, according to the present invention, the ventilation path 5 is provided on the side of the integrated lamp 1 having a much shorter service life than the lamp 10, so that the ventilation path 5 is also changed every time the integrated lamp 1 is replaced due to, for example, disconnection. Will be exchanged.

Therefore, since the replacement is performed quite frequently, the dustproof filter 6 can be provided in the ventilation path 5 without fear of the occurrence of clogging. Therefore, even when the temperature inside the lamp 10 is reduced and the outside air is sucked, dust and the like are removed by the dustproof filter 6, and the dust is reflected on the reflection surface 12 and the lens 13 (see FIG. 2) over the years of use. Thus, it is possible to prevent the illuminance from being reduced due to the accumulation of the illuminance.

Also, since no dust is accumulated inside,
For example, it is not necessary to clean the interior every time a certain time elapses, thereby simplifying maintenance and preventing the reflection surface from being damaged during cleaning. Here, when the lamp 10 is a traffic signal lamp, the integrated lamp 1 is replaced every time a predetermined time elapses from the viewpoint of improving reliability, so that the effect can be further exhibited. .

Further, since the integrated lamp 1 of the present invention is formed so as to be compatible with the conventional integrated lamp, it is manufactured for the conventional integrated lamp and provided with a vent. Even in the case of a lamp, by closing the ventilation hole with a plug or the like and attaching the integrated light bulb 1 of the present invention, a similar operation and effect can be expected thereafter.

FIG. 3 shows another embodiment of the integrated light bulb 1 according to the present invention. In the previous embodiment, a dustproof filter 6 is incorporated in an air passage 5 provided in the socket portion 3 and the whole is formed. In this embodiment, an elbow-shaped pipe 8 having an opening facing downward is detachably provided in the opening 5a on the outer side of the ventilation path 5 in this embodiment, and the dustproof filter 6 is provided on the pipe 8 side. The attachment unit 9 is attached and unitized.

By doing so, the attachment part can be replaced in the integrated lamp 1 of this embodiment,
For vehicles in which the lighting time is shorter than that of a traffic signal lamp and the integrated bulb 1 is not replaced unless the disconnection occurs, and the integrated bulb 1 is not frequently replaced. In the case of a lamp or the like, the attachment part 9 is replaced at the time of a periodic inspection every year or at the time of a vehicle inspection (vehicle inspection) every two years, so that the purpose can be achieved at low cost without causing clogging or the like. Can be reached.

[0019]

As described above, according to the present invention, the socket portion is provided with a ventilation path one of which opens to the inside of the lamp and the other opens to the outside of the lamp, and a dustproof filter is provided in the ventilation path. The use of a light bulb with a built-in socket has a ventilation path on the side of the light bulb with a built-in socket, which has a shorter life span than the lamp and is frequently replaced, which may cause clogging. In this case, the dust filter is provided to prevent the accumulation of dust in the lamp, thereby preventing the performance of the lamp from deteriorating, and exhibiting an extremely excellent effect of extending the service life.

In addition, since dust is not accumulated in the lamp, it is not necessary to clean the inside of the lamp at the time of periodic inspection, for example. When replaced, this type of lamp has an extremely excellent effect in simplifying maintenance of the lamp.

In addition, the dust filter and a part of the ventilation path are unitized to form an attachment portion, and the attachment portion can be replaced from the outside of the lamp.
