Description

  Embodiments described herein relate generally to a lighting device and a lamp.

There is an illuminating device including a storage unit and a light emitting module provided in the storage unit and having a light emitting diode (LED).
Further, a convex portion (also referred to as a bayonet or the like) that is used when the lighting device is attached to the housing of the lamp is provided on the side wall of the storage portion. In this case, the convex part is formed integrally with the storage part.
Here, if the heat radiation in the storage portion is poor, the temperature of the light emitting diode may be excessively increased due to heat generated in the light emitting diode or the like. If the temperature of the light emitting diode rises excessively, the life of the light emitting diode may be shortened.
Moreover, in order to suppress the temperature rise of a light emitting diode, there exists a possibility that the electric power applied to a light emitting diode may be restrict | limited. If the power applied to the light emitting diode is limited, there is a possibility that high luminance cannot be achieved.
Therefore, the storage part is formed from a material having high thermal conductivity. Further, the convex portion formed integrally with the storage portion is also formed from a material having high thermal conductivity.
Here, the material having high thermal conductivity may have conductivity.
Further, when the lighting device is attached to the casing of the lamp, the convex portion and the casing of the lamp are rubbed.
Therefore, there is a risk that conductive dust may be generated when the lighting device is attached to the housing of the lamp.
If conductive dust is generated, a short circuit or the like may easily occur.
Therefore, development of a lighting device that can suppress the generation of conductive dust has been desired.

The number and size of the control elements 23 are not limited to those illustrated, and can be appropriately changed according to the number and specifications of the light emitting elements 22a.

The wiring pattern 24 is provided on at least one surface of the substrate 21.
The wiring pattern 24 can be provided on both surfaces of the substrate 21, but it is preferable to provide the wiring pattern 24 on one surface of the substrate 21 in order to reduce the manufacturing cost.
The wiring pattern 24 is provided with an input terminal 24a.
A plurality of input terminals 24a are provided. A power feeding terminal 41 is electrically connected to the input terminal 24a. Therefore, the light emitting element 22 a is electrically connected to the power feeding terminal 41 through the wiring pattern 24.

As shown in FIG. 4, the socket 30 is provided with a main body 30a, a female terminal 30b, and a wiring 30c.
The main body 30a is made of an insulating material such as resin. A convex portion 30a1 is provided on the side wall of the main body portion 30a. The socket 30 is held by the main body part 10 by fitting the convex part 30 a 1 into the concave part provided in the main body part 10.

The female terminal 30b extends inside the main body 30a.
One end of the female terminal 30b is exposed on one end surface of the main body 30a. The power feeding terminal 41 is fitted into the end of the female terminal 30b exposed at one end face of the main body 30a.
A wiring 30c is electrically connected to the other end of the female terminal 30b.

Although the two power supply terminals 41 are illustrated, the number and shape of the power supply terminals 41 are not limited to those illustrated, and can be changed as appropriate.

As described above, the main body 10 is preferably formed from a highly heat conductive resin.
High thermal conductive resins include those obtained by mixing a conductive material such as carbon with a resin. Therefore, some highly heat conductive resins have conductivity.
When a highly heat conductive resin having conductivity is used, a short circuit occurs when the main body 10 and the power supply terminal 41 come into contact with each other.
For this reason, a holding portion 42 made of an insulating material is provided between the main body portion 10 and the power supply terminal 41.

The holding part 42 is provided inside a hole 10 a provided in the main body part 10.
The hole 10a penetrates between the end 10b of the main body 10 on the side where the light emitting module 20 is provided and the end 10c on the side where the socket 30 is provided.
Moreover, when the illuminating device 1 is an illuminating device for vehicles, the temperature of use environment will be -40 degreeC-85 degreeC. Therefore, it is preferable that the linear expansion coefficient of the high thermal conductive resin that is the material of the main body portion 10 and the linear expansion coefficient of the resin that is the material of the holding portion 42 are as close as possible. In this way, even if the lighting device 1 is used in an environment with a large temperature change, it is possible to reduce the thermal stress generated between the main body 10 and the holding unit 42.
In this case, the holding portion 42 can be formed using a resin included in the high thermal conductive resin.
For example, when the high thermal conductive resin is a fiber or particle made of carbon mixed with PET, the holding portion 42 can be formed using PET.

Next, the convex part 14 is further demonstrated.
The convex portion 14 is used when the lighting device 1 is attached to the housing 101 of the lamp 100.
Therefore, first, a procedure for attaching the lamp 100 and the lighting device 1 will be described.
6A to 6C are schematic cross-sectional views for illustrating the lamp 100 according to the present embodiment.
FIG. 6A is a schematic exploded view of the lamp 100.
FIG. 6B is a schematic cross-sectional view of the lamp 100.
FIG. 6C is a schematic enlarged view for illustrating the relationship between the protrusion 14 and the protrusion 101c.
The lamp 100 illustrated in FIGS. 6A to 6C is a one-lamp stop lamp. However, the lamp 100 is not limited to a one-lamp stop lamp.
FIGS. 7A to 7C are schematic views for illustrating a procedure for attaching the illumination device 1 to the housing 101 of the lamp 100. FIG.

As shown in FIGS. 6A and 6B, the lamp 100 is provided with a lighting device 1, a housing 101, a cover 102, a reflecting portion 103, and a seal member 104.
The casing 101 has a box shape with one end opened. The housing 101 can be formed from, for example, a resin that does not transmit light.
A mounting hole 101 a into which the storage portion 11 is inserted is provided on the bottom surface of the housing 101.
A concave portion 101b into which the convex portion 14 is inserted is provided at the periphery of the mounting hole 101a. (See FIGS. 7A to 7C)
As shown in FIG. 6C, a plurality of protrusions 101c are provided inside the housing 101 and on the periphery of the mounting hole 101a.
In addition, although the case where the mounting hole 101a and the protruding portion 101c are directly provided in the housing 101 is illustrated, the mounting member is provided in the housing 101, and at least one of the mounting hole 101a and the protruding portion 101c is provided in the mounting member. It may be.
The number and arrangement positions of the protrusions 101c are the same as the number and arrangement positions of the recesses 14b. As will be described later, when the lighting device 1 is attached to the lamp 100, the protrusions 101c are fitted with the corresponding recesses 14b. Therefore, the attachment position in the rotation direction of the illuminating device 1 can be prescribed | regulated.

The protrusion 101c is preferably made of a material that is insulative and softer than the material of the protrusion 14. In this way, it is possible to suppress the generation of conductive dust described later.
The protrusion 101c can be formed using a resin such as ABS (acrylonitrile butadiene styrene) or PC.

There is no limitation in the form of the recessed part 14b, and it should just be able to fit the projection part 101c. For example, as illustrated in FIG. 2, the concave portion 14 b may be opened at the outer peripheral side end surface of the convex portion 14, or may not be opened at the outer peripheral side end surface of the convex portion 14. May be. In addition, the recess 14b may be a groove, a hole that penetrates the projection 14, or a hole with a bottom that does not penetrate the projection 14.
Moreover, the recessed part 14b shall exhibit the taper shape from which a cross-sectional dimension becomes short as it leaves | separates from the flange part 12. FIG.
If it is set as the recessed part 14b which exhibits a taper shape, since the projection part 101c can be drawn in, positioning becomes easy. Further, rattling in the rotation direction can also be suppressed.

As shown in FIGS. 6A and 6B, the cover 102 is provided so as to close the opening of the housing 101. The cover 102 can be formed from a light-transmitting resin or the like.
The cover 102 may have a function such as a lens.
The reflection part 103 reflects the light irradiated from the illuminating device 1, and forms a predetermined light distribution pattern. The reflecting portion 103 is provided inside the housing 101 and concentric with the central axis of the mounting hole 101a.

The seal member 104 is provided on the surface of the flange portion 12 on the convex portion 14 side. The seal member 104 can be formed from an elastic material such as rubber or silicone.
When the lighting device 1 is attached to the lamp 100, the seal member 104 is sandwiched between the flange portion 12 and the housing 101. Therefore, the internal space of the lamp 100 is sealed by the seal member 104.

The lighting device 1 can be attached as follows.
As shown in FIG. 7A, a concave portion 101b into which the convex portion 14 is inserted is provided at the periphery of the mounting hole 101a.
First, as shown in FIG. 7B, the storage portion 11 of the lighting device 1 is inserted into the mounting hole 101a. At this time, the convex portion 14 is inserted into the concave portion 101b.
Next, as shown in FIG. 7C, the lighting device 1 is rotated so that the protrusion 101c is fitted with the corresponding recess 14b.
At this time, since the elastic seal member 104 is sandwiched between the flange portion 12 and the housing 101, the protruding portion 101c and the concave portion 14b are brought into close contact with each other by the elastic force.
As described above, the lighting device 1 is attached to the housing 101 of the lamp 100. Moreover, the attachment position in the rotation direction and the axial direction of the illumination device 1 is defined.

Here, when the lighting device 1 is rotated, the convex portion 14 and the protruding portion 101c are rubbed.
As described above, the convex portion 14 may be formed of a high thermal conductive resin. The high thermal conductive resin is harder and more brittle than a general resin. Therefore, rubbing between the convex portion 14 and the protruding portion 101c may cause dust to be generated due to the convex portion 14 being chipped.
Moreover, when the illuminating device 1 is an illuminating device for vehicles, the vibration accompanying driving | running | working will add to the illuminating device 1. FIG. Therefore, dust may be generated even after the lighting device 1 is attached.
In addition, when the high thermal conductive resin includes a conductive material such as carbon, the generated dust has electrical conductivity.
If conductive dust is generated, a short circuit or the like may easily occur.

According to the knowledge obtained by the present inventor, it has been found that if a protrusion is provided on the convex portion 14 and a concave portion to be fitted with the protrusion is provided on the housing 101 side, there is a risk that the generation of dust may increase. did.
Therefore, in the present embodiment, the convex portion 14 is provided with the concave portion 14b, and the protruding portion 101c fitted to the concave portion 14b is provided on the housing 101 side.
In this way, even if the convex part 14 is formed from a highly heat conductive resin having conductivity, the generation of conductive dust can be suppressed. Therefore, occurrence of a short circuit or the like can be suppressed.
