Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to vehicle lighting. More specifically, the present invention relates to a double-scattering vehicle light useful for lighting stop lights, side lights, and illuminated lights in vehicles such as automobiles, trucks, and special vehicles. is there.

[0002]

[Prior art and its problems]

 Conventionally, vehicles such as automobiles, trucks, and special vehicles have various types of vehicle lights such as stop lights, side lights, and illuminated lights in consideration of their functionality, safety, and beauty. Is equipped with. Incandescent lamps are very commonly used as the light source for such vehicle lights.

However, since the light source of the incandescent lamp has a short life, there is a problem that the incandescent lamp must be frequently replaced at the end of its life, and the cost for the replacement cannot be neglected. . In addition to the problem of complexity and cost, if the incandescent lamp of the vehicle lamp burns out while the vehicle is traveling, a serious problem that driving safety cannot be ensured will occur. Become.

The incandescent lamp has a problem that the electric power is wasted because the electric power consumption and the heat generation amount are very large. Further, such conventional vehicle lighting is not satisfactory not only in terms of functionality and safety, but also in terms of beauty. Conventional vehicle lighting has a structure that creates a difference in the density of scattered light and emphasizes the beauty of scattered light, but in the case of an incandescent light source, the difference in density of scattered light depending on the scattering direction. Is not very noticeable and lacks the beauty of scattered light.

The present invention has been made in view of the circumstances as described above, and provides a vehicle lighting that solves the drawbacks of the conventional device and has improved functionality, safety, and beauty. It is an object.

[0006]

[Means for Solving the Problems]

 This invention solves the above problems by using a light source, a reflector, a first-order scatterer made of a transparent diffuse refraction cover that covers the light source, and a first-order scatterer that covers the first-order scatterer. A double-scattering vehicle lamp having a secondary scatterer according to claim 1, wherein the light source is a high-intensity light emitting diode.

[0007]

[Action]

 That is, the present invention has a great feature in that a high brightness light emitting diode (LED) is used as a light source instead of a conventional incandescent lamp, and a double scattering structure is adopted together with a reflecting plate. In other words, by using a high-intensity light emitting diode as a light source, not only can the light source be made brighter, but also power consumption and heat generation can be reduced and life can be extended.

[0008] Furthermore, by providing double scatterers, it is possible to expand the light scattering range from the light emitting diode having a smaller irradiation angle than that of the incandescent lamp, and further, the light scattering depending on the scattering direction. It is also possible to significantly increase the difference, so that a beautiful scattered light can be obtained. Of course, in this invention, the light emitting diode as a light source may use one or a plurality of ones having various hues, and by increasing the number thereof, it is possible to increase the brightness of one layer.

Further, in the present invention, the shape of the scatterer is not particularly limited as long as it is a cover such as a curved type, a cylindrical type, or a rectangular tube type. Hereinafter, the present invention will be described in more detail with reference to examples.

[0010]

【Example】

 For example, as illustrated in FIG. 1, a vehicle lamp of the present invention is mounted on a resin substrate (6) on which a plurality of light emitting diodes (1) as light sources are arranged in a circuit, and a transparent irregular refraction cover having a cut surface. It is covered with a primary scatterer (2) made of a body resin or glass, and the primary scatterer (2) has the same structure and function as the primary scatterer and has a size equal to that of the primary scatterer. It is covered with a secondary scatterer (3) made of a large resin or glass and attached to the pedestal (4). On the surface of the substrate (6), a reflection plate (6) made of ceramic, resin or the like is attached.

The base (4) is made of resin, and the base (4) is provided with the waterproof rubber (5) as a ring-shaped plate or a circular plate. Further, the secondary scatterer (3) and the pedestal (4) are also provided with screw portions (7) and (8) which are engaged with each other. In this case, the screw part (7) may be formed on a bulging ring part integrally formed with the secondary scatterer (3) or may be a resin ring separate from the secondary scatterer (3). The secondary scatterer (3) may be made of a sheet-like material or the like, and may be disposed by being adhesively fixed to the peripheral portion of the opening end of the secondary scatterer (3).

FIG. 2 and FIG. 3 each show an example of a structure for mounting and fixing to the pedestal (4) in the case of this example. The primary scatterer (2) is fixed to the substrate (6) using bolts (9) and nuts (10), and this is placed at a desired portion of the pedestal (4). ) And the bolts (12) and nuts (13) through the mounting through holes (11) to tighten the pedestal (4) to the required parts of the vehicle and the power supply through the through holes (14 ) And connected to the vehicle.

The circuit connection relationship of the light source (1) according to the present invention can be as shown in FIG. 4, for example, and a direct current power source having a required polarity can be connected to the points A and B. On the resin substrate (6), a constant voltage IC is mounted together with the light emitting diode (1) and the low voltage device (15) which form the circuit of FIG. This IC has a certain light and color, and when the vehicle is 24D (large size), it can reach 28 to 29 V, so it is necessary to prevent damage to the light emitting diode due to heat. The purpose is to prevent this damage.

In the above structural example, the presence of the screw portions (7) and (8) and the waterproof rubber (5) makes the circuit of the light emitting diode (1) and the circuit board (6) on which the light emitting diode (1) is mounted waterproof. The structure is secured and easy to attach and detach. In addition, various other types of mounting and fixing structures are appropriately adopted. For example, in FIG. 5, unlike the above example, the waterproof rubber (16) is arranged in a ring shape on the peripheral portion of the primary scatterer (2), and the peripheral portion of the secondary scatterer (3) is arranged above it. After mounting on, the threaded portions (18) and (19) are joined by the ring-shaped fastening body (17). Even in this case, it is easy to put on and take off, the waterproof property is good, and it is possible to stably realize the excellent brightness as the light source of the high brightness light emitting diode (1).

Further, FIG. 6 shows an example using a rectangular light emitting diode (23). Such various modes are possible. In the example of FIG. 6, the primary scatterer (2) is adhesively fixed on the reflection plate (61) or brought into contact with the secondary scatterer (3) to fix the peripheral edge of the pedestal (4). The cover body (20) covers the entire surface.

The bolts (21) and nuts (22) may be attached to the vehicle.
