The heat dissipating body 82 has a columnar base 89 and a plurality of heat dissipating fins 90 projecting radially from the periphery of the base 89.

A circular protrusion 91 that fits into the opening 87 of the reflector 81 is formed on the lower surface of the base 89, and a flat or planar heat conduction surface 92 is formed on the lower surface of the protrusion 91. At the center of the heat conducting surface 92 corresponding to the central axis of the instrument device 15, a cylindrical projection 93 is formed protruding. A plurality of attachment portions 94 to which attachment springs 86 are attached are formed around the base portion 89.

The socket 83 includes a socket main body 95 made of an insulating synthetic resin and formed in an annular shape, and a pair of terminals (not shown) arranged on the socket main body 95.

In the center of the socket body 95, a circular opening 96 through which the protrusion 49 of the base 30 of the lamp device 14 is inserted is formed. An annular socket surface 97 is formed on the lower surface of the socket body 95 so as to face the base surface 48 of the lamp device 14. In the socket surface 97, a pair of connection holes 98 into which the pair of lamp pins 71 of the lamp device 14 are inserted are formed in a long hole shape along the circumferential direction.

Each key groove 100 is formed in a substantially L shape having a vertical groove 100a formed along the vertical direction and a horizontal groove 100b formed along the circumferential direction on the upper side of the socket body 95. The restriction projection 99 and the key groove 100 of the socket 83 and the groove 46 and the key 47 of the lamp device 14 are provided at corresponding positions. The key groove 100 of the socket 83 and the key 47 of the lamp device 14 constitute an attachment / detachment structure 101 that rotates the base 30 with respect to the socket 83 to attach / detach.

The socket body 95 is formed with a plurality of bosses 102 that open to the socket surface 97. Inside the boss 102, a sleeve 103 that penetrates the boss 102 and contacts the reflector 81, a coil spring 104 as an elastic body disposed on the outer periphery of the sleeve 103, the sleeve 103, and the reflector 81 penetrates the heat sink.

Then, the socket body 95, the sleeve 103, the coil spring 104, the screw 105, and the like constitute a pressing structure 106 that presses the contact surface 50 of the base 30 against the heat conducting surface 92 by mounting the base 30 to the socket 83. .

The terminal block 85 is electrically connected to the terminal of the socket 83.

And, in the lighting device 11 composed of the lamp device 14 and the fixture device 15 in this way, for example, a plurality of types of lamp devices 14 are provided according to the difference in the output of the light emitting module 27, etc. Accordingly, when a plurality of types of fixture devices 15 are provided for each type of the lamp device 14, the compatible types of lamp devices 14 and the fixture device 15 are combined.

This is to prevent the lamp device 14 having a high output from being mounted on the fixture device 15 that is compatible with the lamp device 14 having a low output. That is, when the fixture device 15 is optimized for heat dissipation performance in accordance with the output of the lamp device 14, if the lamp device 14 with a large output is mounted on the fixture device 15 suitable for the lamp device 14 with a small output, the lamp device 14 The desired performance may not be achieved. On the other hand, even if the lamp device 14 with a small output is mounted on the fixture device 15 to which the lamp device 14 with a large output is fitted, the heat dissipation performance is only excessive and the desired performance can be achieved. In other words, the lamp device 14 can be mounted on the fixture device 15 that fits the lamp device 14 that is larger than its own output, and cannot be mounted on the fixture device 15 that fits the lamp device 14 smaller than its own output. It is desirable to do.

Furthermore, it is desirable to set the suitability of the fixture device 15 for the lamp device 14 depending on the difference in power supply voltage input to the lamp device 14. For example, when there is a lamp device 14 that operates at 100V and a lamp device 14 that operates at 200V, it is necessary to set a device device 15 dedicated to 100V and a device device 15 dedicated to 200V.

Thus, it is preferable to set the adaptation between the lamp device 14 and the fixture device 15 according to the difference between the output of the lamp device 14 and the input voltage. The suitability between the lamp device 14 and the appliance device 15 can be set, for example, by changing the position and size of the groove portion 46 of the base 30 and the restriction projection 99 of the socket 83 for each type.

FIG. 5 shows a plan view of the base 30. A key 47 protrudes from the periphery of the base member 29 at three equally spaced intervals in the circumferential direction, and one of the three keys 47 serves as a reference key 47s. Further, in the peripheral portion of the base member 29, groove portions 46 are formed at three locations separated from the straight line L1 connecting the center of the base member 29 and the reference key 47s by predetermined angles α, β, γ in the circumferential direction. ing. The grooves 46 formed in the 100V base 30 and the grooves 46 formed in the 200V base 30 are relatively shifted in the positions of the angles α, β, and γ from the reference key 47s. Further, the circumferential length X of the groove 46 is set to be shorter in the lamp device 14 having a larger output than in the lamp device 14 having a smaller output.

FIG. 6 shows a bottom view of the socket 83. On the inner peripheral surface of the socket body 95, key grooves 100 are provided at three positions that are equally spaced in the circumferential direction, and one of these three key grooves 100 is used as a reference key groove 100s. In addition, the socket body 95 has a restriction protrusion 99 that protrudes at a position and size that allows insertion of the groove 46 formed in the base 30 of the lamp device 14 that matches the key groove 100s as a reference. Yes.

Incidentally, the dimension X in the circumferential direction of the groove 46 of the lamp device 14 with a small output is larger than the dimension Y of the restricting projection 99 of the socket 83 corresponding to the lamp device 14 with a large output. For this reason, the lamp device 14 having a small output can be mounted on the base 30 that is suitable for the lamp device 14 having a large output. However, the heat radiation performance is ensured even if it is mounted on the fixture device 15 that is suitable for the lamp device 14 having a large output.

On the other hand, the circumferential dimension X of the groove 46 of the lamp device 14 having a high output is smaller than the dimension Y of the restricting projection 99 of the socket 83 corresponding to the lamp device 14 having a low output. For this reason, the lamp device 14 having a large output cannot be attached to the socket 83 suitable for the lamp device 14 having a small output due to interference with the restricting protrusion 99. That is, the lamp device 14 having a high output cannot be attached to the fixture device 15 to which the lamp device 14 having a low output is suitable, and safety is ensured.

Note that the positions of the groove 46 and the regulation protrusion 99 are different between the lamp device 14 for 100 V and the device device 15 for 200 V, and the lamp device 14 for 100 V and the device device 15 for 100 V, and the output is small. Moreover, since both of the large outputs are not compatible, it is possible to prevent erroneous mounting.

Next, another method for adapting the lamp device 14 and the fixture device 15 will be described. For example, different types of lamp devices 14 are set depending on whether or not the cap 30 has the recess 51, and only the lamp device 14 having the recess 51 in the cap 30 can be attached to the fixture device 15 having the protrusion 93. A suitable type of lamp device 14 and fixture device 15 are combined. In the lamp device 14 having the recess 51 in the base 30, the inner diameter and depth of the recess 51 of the base 30 and the diameter and protrusion amount of the projection 93 of the instrument device 15 are changed depending on the type. You can set the type.

Next, attachment of the lamp device 14 to the appliance device 15 will be described.

First, the lamp device 14 is inserted from the lower surface opening of the fixture device 15, and each groove portion 46 of the base 30 is passed upward in accordance with each regulation protrusion 99 of the socket 83, and each key 47 of the base 30 is set to each of the socket 83. The projection 49 of the base 30 is inserted into the opening 96 of the socket 83 and inserted along the vertical groove 100 a of the keyway 100.

Here, in the case of a combination of a suitable type of lamp device 14 and the fixture device 15, that is, when the lamp device 14 having the recess 51 is to be attached to the fixture device 15 having the projection 93, the recess of the base 30 51 fits into the protrusion 93 of the radiator 82, in other words, the protrusion 93 of the radiator 82 is inserted into the recess 51 of the base 30. Therefore, the protruding portion 49 of the base 30 can be inserted to a predetermined insertion position in the opening 96 of the socket 83, and the contact surface 50 of the base 30 is connected to the heat conducting surface 92 of the radiator 82 via the heat conducting sheet 22. It can be made to contact. At this time, each lamp pin 71 protruding from the base 30 is inserted into each connection hole 98 of the socket 83.

By rotating the lamp device 14 inserted up to a predetermined insertion position with respect to the socket 83 by a predetermined angle in the mounting direction, each key 47 of the base 30 enters into the lateral groove 100b of each key groove 100 of the socket 83 and gets caught, The lamp device 14 is attached to the socket 83. At this time, each lamp pin 71 of the base 30 moves in each connection hole 98 of the socket 83 and contacts each terminal disposed in each connection hole 98 to be electrically connected.

When the key 47 of the base 30 enters the lateral groove 100b of the key groove 100 of the socket 83, the socket body 95 is pushed down against the coil spring 104 by the key 47 of the base 30. As a result, the repulsive force of the coil spring 104 acts in a direction to press the base 30 against the heat conducting surface 92 of the radiator 82 via the socket body 95, and the contact surface 50 of the base 30 passes through the heat conducting sheet 22 to the radiator 82. The heat conduction surface 92 is pressed against.

Therefore, in a state where the base 30 of the lamp device 14 is attached to the socket 83, the contact surface 50 of the base 30 is in close contact with the heat conductive surface 92 of the radiator 82 via the heat conductive sheet 22, and from the base 30 of the lamp device 14 It is possible to conduct heat efficiently to the radiator 82.

On the other hand, in the case of a combination of the incompatible lamp device 14 and the appliance device 15, that is, when the lamp device 14 having no recess 51 is to be attached to the appliance device 15 having the projection 93, the cap 30 When the protrusion 49 is to be inserted into the opening 96 of the socket 83, the contact surface 50 of the base 30 abuts on the protrusion 93 of the radiator 82, and the protrusion 49 of the base 30 is inserted into the opening 96 of the socket 83. Cannot be inserted up to a predetermined device position. Therefore, even if it is attempted to rotate the lamp device 14 that has not been inserted to the predetermined insertion position with respect to the socket 83, each key 47 of the base 30 will not enter the lateral groove 100b of each key groove 100 of the socket 83. The lamp device 14 cannot be mounted in the socket 83. Therefore, it is possible to prevent the lamp device 14 and the appliance device 15 of an incompatible type from being combined.

Further, when removing the lamp device 14 attached to the fixture device 15, first, the key 47 of the base 30 is moved to the respective direction of the socket 83 by rotating the lamp device 14 in the removal direction opposite to that at the time of attachment. The key groove 100 moves from the horizontal groove 100b to the vertical groove 100a. Subsequently, by moving the lamp device 14 downward, each lamp pin 71 is removed from each connection hole 98 of each socket 83, each groove portion 46 of the base 30 is released from each regulation protrusion 99 of the socket 83, and the base 30 The keys 47 are removed from the key grooves 100 of the socket 83, and the base 30 is detached from the opening 96 of the socket 83, so that the lamp device 14 can be removed from the socket 83.

Next, lighting of the lamp device 14 will be described.

When power is supplied to the lighting circuit 25 from the power line through the terminal block 85, the terminal of the socket 83 and the lamp pin 71 of the lamp device 14, the lighting power is supplied from the lighting circuit 25 to the semiconductor light emitting element of the light emitting module 27. Light. The light emitted from the light emitting unit 56 by turning on the semiconductor light emitting element travels in the light guide unit 62 of the reflector 61, passes through the light transmitting cover 26, and is emitted from the lower surface opening of the instrument device 15.

In addition, the heat generated by the semiconductor light emitting element of the light emitting module 27 at the time of lighting is mainly efficiently conducted to the light emitting module mounting portion 45 of the base member 29 that is thermally bonded from the substrate 55 of the light emitting module 27. Then, heat is efficiently conducted from the light emitting module mounting portion 45 of the base member 29 to the heat dissipating member 82 that is in close contact with the heat conducting sheet 22, and the heat dissipating from the surface of the heat dissipating member 82 including the plurality of heat dissipating fins 90 to the air. The

Further, part of the heat conducted from the lamp device 14 to the radiator 82 is also conducted to the reflector 81, the plurality of attachment springs 86, and the attachment plate 84, respectively, and is also radiated into the air from these.

Further, the heat generated by the lighting circuit 25 is transmitted to the case 28 and the translucent cover 26, and is radiated from the surface of the case 28 and the translucent cover 26 to the air.

Next, the protrusion dimension of the protrusion 93 from the heat conduction surface 92 of the instrument device 15 will be described.

As shown in FIG. 7, the protrusion dimension h1 of the protrusion 93 from the heat conduction surface 92 is equal to the depth dimension h2 of the recess 51 from the contact surface 50 and the protrusion dimension h3 of the heat conduction sheet 22 from the contact surface 50. It is smaller than the above dimension and has a relationship of h1 <h2 + h3.

Due to the relationship of h1 <h2 + h3, the contact surface 50 of the base 30 is connected to the heat conductive surface 92 of the heat sink 82 via the heat conductive sheet 22 even when the protrusion 93 of the heat sink 82 is inserted into the recess 51 of the base 30. It can be reliably contacted.

If h1> h2 + h3, the protrusion 93 of the radiator 82 is inserted into the recess 51 of the base 30, and the tip surface of the protrusion 93 comes into contact with the bottom surface of the recess 51. Cannot be brought into contact with the heat conducting surface 92 of the radiator 82 via the heat conducting sheet 22.

Further, as shown in FIG. 8, the protrusion dimension h1 of the protrusion 93 from the heat conduction surface 92 is larger than the dimension obtained by combining the movement dimension h4 of the socket 83 and the protrusion dimension h3 of the heat conduction sheet 22 from the contact surface 50. , H1> h4 + h3.

Due to the relationship of h1> h4 + h3, the lamp device 14 having the recess 51 can be attached to the fixture device 15 having the protrusion 93, but the lamp device 14 not having the recess 51 cannot be attached in any way. it can.

Even if h1 <h4 + h3, even if the lamp device 14 that does not have the recess 51 is to be mounted on the fixture device 15 having the protrusion 93, the contact surface 50 of the base 30 comes into contact with the protrusion 93, and the base 30 Therefore, the lamp device 14 cannot be mounted on the socket 83 because the protrusion 49 cannot be inserted to a predetermined device position in the opening 96 of the socket 83. However, when the socket body 95 is forcibly pushed down by placing a finger on the socket body 95, the protrusion 49 of the base 30 is inserted to a predetermined device position in the opening 96 of the socket 83, and in this state There is a possibility that the lamp device 14 can be rotated and attached to the socket 83.

Therefore, due to the relationship of h1> h4 + h3, the lamp device 14 having no recess 51 can be prevented from being mounted in any way.

Further, as shown in FIG. 9, the protrusion dimension h1 of the protrusion 93 from the heat conduction surface 92 is smaller than the dimension h5 from the heat conduction surface 92 to the socket surface 97, and h1 <h5.

Due to the relationship of h1 <h5, when the base 30 is mounted in the socket 83, even if the base 30 is inserted obliquely with respect to the socket 83, the heat conductive sheet 22 of the base 30 may contact the protrusion 93. Therefore, it is possible to prevent the heat conductive sheet 22 from being peeled off or torn.

If the relationship of h1> h5 is satisfied, when the cap 30 is inserted into the socket 83 when the cap 30 is inserted into the socket 83, the heat conductive sheet 22 of the cap 30 contacts the protrusion 93. It is easy to cause the heat conductive sheet 22 to be peeled off or torn.

As described above, according to the illumination device 11 of the present embodiment, the lamp device 14 having the recess 51 can be mounted on the fixture device 15 having the protrusion 93, and the lamp device 14 not having the recess 51 cannot be mounted. Therefore, a suitable type of lamp device 14 and fixture device 15 can be used in combination.

Further, since the concave portion 51 is provided in the contact surface 50 of the base 30 instead of the projection 93, the work of attaching the heat conductive sheet 22 to the contact surface 50 can be facilitated.

Further, in the lighting device 11 having the attachment / detachment structure 101 for rotating the base 30 with respect to the socket 83 to attach / detach, the recess 51 is provided in the center of the contact surface 50 and the protrusion 93 is provided in the center of the heat conduction surface 92. Therefore, the area of the recess 51 opening in the contact surface 50 can be minimized, the area of the contact surface 50 can be ensured, and sufficient heat conduction performance from the contact surface 50 to the heat conduction surface 92 can be ensured.

In addition, the recess 51 is provided in the center of the contact surface 50 and the protrusion 93 is provided in the center of the heat conducting surface 92, so that when the base 30 is rotated with respect to the socket 83 and attached / detached. Thus, it is possible to prevent the protrusions 93 from coming into contact with the heat conductive sheet 22 on the contact surface 50 and causing damage.

Further, since the protrusion dimension of the protrusion 93 from the heat conduction surface 92 is smaller than the total dimension of the depth dimension of the recess 51 from the contact surface 50 and the protrusion dimension of the heat conduction sheet 22 from the contact surface 50, the base 30 Even when the protrusion 93 of the radiator 82 is inserted into the recess 51, the contact surface 50 of the base 30 can be reliably brought into contact with the heat conducting surface 92 of the radiator 82 via the heat conducting sheet 22.

Further, the protrusion dimension of the protrusion 93 from the heat conduction surface 92 is larger than the total dimension of the movement dimension of the socket 83 and the protrusion dimension of the heat conduction sheet 22 from the contact surface 50. In contrast, the lamp device 14 having the recess 51 can be mounted, but the lamp device 14 not having the recess 51 cannot be mounted in any way.

Further, since the protrusion dimension h1 of the protrusion 93 from the heat conduction surface 92 is smaller than the dimension h5 from the heat conduction surface 92 to the socket surface 97, when the base 30 is attached to the socket 83, the base 30 is in relation to the socket 83. Even if the heat conductive sheet 22 is inserted obliquely, the heat conductive sheet 22 of the base 30 does not come into contact with the protrusions 93, and the heat conductive sheet 22 can be prevented from being peeled off or torn.

Note that the heat conducting surface 92 is not limited to being provided on the radiator 82 but may be provided on the socket 83. In this case, the socket 83 and the radiator 82 may be provided integrally. The protrusion 93 may also be provided on the socket 83 as long as it is provided on the heat conduction surface 92 with which the contact surface 50 of the base 30 contacts.

Also, in the lamp device 14 having the recess 51 in the base 30, a combination of a plurality of types is possible by changing the inner diameter and depth of the recess 51 of the base 30 and the diameter and protrusion amount of the projection 93 of the instrument device 15 for each type. Can be set.

Furthermore, it has a relationship between the recess 51 and the protrusion 93 described here, and it is possible to cope with the case where the type of the lamp device 14 further increases by combining the matching method of the groove 46 and the restriction protrusion 99 described above. Can do.

For example, in the above description, the adaptation of the fixture device 15 and the lamp device 14 in which the input voltage is set in advance has been described, but the lamp device 14 that can be used at both 100 V and 200 V is assumed as the type of the lamp device 14. Even in this case, it is possible to prevent erroneous mounting.

That is, the recess 51 is provided in the lamp device 14 corresponding to 100V and 200V, and the protrusion 93 is provided in the instrument device 15 corresponding to 100V and 200V. Here, the instrument device 15 corresponding to 100V and 200V means that 100V and 200V are properly used by the user, and the constituent members are common. Below, the case where the socket 83 for 200V is used as the instrument apparatus 15 corresponding to 100V and 200V is demonstrated.

In this case, as shown in FIG. 10 (a), the lamp device 14 for 100V and 200V does not have the recess 51, so that the protrusion 93 can be mounted on the instrument device 15 corresponding to 100V and 200V. Can not. Assuming that 100V is connected to the 100V and 200V compatible appliance device 15 without the

projection

93, 100V power may be supplied to the 200V lamp device 14, and in this case, the lamp device 14 is turned on. I can't let you.

On the other hand, when the lamp device 14 having the recess 51 is attached to the instrument device 15 for 100V and 200V having no protrusion 93, it can be attached as shown in FIG. 10 (b).

Further, when the positions of the restricting protrusion 99 and the groove 46 are shifted between 100V and 200V, and these dimensions are changed between a small output and a large output, the

lamp devices

14 and 100V corresponding to 100V and 200V are used. A method of fitting with the instrument device 15 for 200V will be described.

FIG. 11 is a partially enlarged view showing a state in which the socket 83 of the fixture device 15 and the base 30 of the lamp device 14 are aligned. FIG. 11 (a) shows the restricting protrusion 99 of the socket 83 that fits the lamp device 14 with a small output, and FIG. 11 (b) shows the restricting protrusion 99 of the socket 83 that fits the lamp device 14 with a large output. Show. As the restriction protrusion 99, a restriction protrusion 99 for 100V (for 100V) and a restriction protrusion 99 for 200V (for 200V) are shown in FIG. A straight line L1 indicates a straight line connecting the center of the base 30 and the reference key 47s. The straight line L2 is a straight line connecting the center of the base 30 and the center of the 100V regulating protrusion 99 (for 100V) when the key 47s serving as the reference of the base 30 and the key groove 100 of the socket 83 are aligned. Is shown. A straight line L3 indicates a straight line connecting the center of the base 30 and the center of the regulating protrusion 99 for 200V (for 200V). The angle θ formed by the straight line L2 and the straight line L3 is set to 5 °, for example.

Here, as shown in FIG. 11, the groove 46 of the base 30 of the lamp device 14 corresponding to the input voltages of 100V and 200V is a regulation projection 99 for 100V (for 100V) and a regulation projection 99 for 200V ( (For 200V) and both are formed with dimensions that can pass through. Here, the groove 46S shown in FIG. 11 (a) is set to have a larger dimension in the circumferential direction than the groove 46L shown in FIG. 11 (b). The groove 46S can be inserted with a 100V regulating projection 99 (for 100V) and a 200V regulating projection 99 (for 200V) to which the lamp device 14 having a large output can be fitted, but the groove 46L has a small output. The lamp device 14 cannot be inserted by interfering with both the regulation protrusion 99 for 100V (for 100V) and the regulation protrusion 99 for 200V (for 200V).

Thus, it is possible to realize the lamp device 14 that is compatible with the instrument device 15 for 100V and 200V and that can prevent erroneous mounting on the instrument device 15 having different corresponding outputs.

In addition, in the lamp device 14 having the recess 51 in the base 30, the inner diameter and depth of the recess 51 of the base 30 and the diameter and protrusion amount of the projection 93 of the instrument device 15 are changed depending on the type, thereby supporting 100 V and 200 V. The fixture device 15 and the lamp device 14 to be adapted can be adapted according to the difference in output.

For example, the protrusion dimension h1 of the protrusion 93 of the fixture device 15 corresponding to the lamp device 14 having a high output is made smaller than the protrusion dimension h1 of the protrusion 93 of the fixture device 15 corresponding to the lamp device 14 having a low output. Further, the recess 51 of the lamp device 14 is formed in accordance with the dimension of the protrusion 93.

Accordingly, as shown in FIG. 12 (a), the lamp device 14 having a small output can be mounted on the fixture device 15 corresponding to the lamp device 14 having a large output, but has a large output as shown in FIG. 12 (b). The lamp device 14 cannot be mounted on the fixture device 15 corresponding to the lamp device 14 having a small output.
