Description

[Technical field]

[0001] The present invention relates to an interior lamp for a vehicle. [Background technology]

[0002] It has long been common for users to convert their vehicle interior lamps to LEDs based on their preferences, and many products for this purpose have been released.

[0003] Among such products, for example, there are many that are aimed at users who prioritize brightness, and which efficiently use the area of ​​the vehicle's interior lamp by arranging a large number of LED chips on a board, and then connecting the board to a socket (metal fitting) that is originally installed on the vehicle with a lead wire to convert it into an LED (see Non-Patent Document 1). [Prior art documents] [Non-patent literature]

[0004] [Non-Patent Document 1] SPAREE website "Hiace LED interior lamp Toyota 200 series car model specific map lamp" page https: / / suparee.jp / products / %E3%83%8F%E3%82%A4%E3%82%A8%E3%83%BC%E3%82%B9-led-%E3%83%AB%E3%83%BC%E3%83%A0-%E3%83%A9%E3%83%B3%E3%83%97 Summary of the Invention [Problem to be solved by the invention]

[0005] However, the product described in Non-Patent Document 1 above (a product in which a board on which many LEDs are mounted is connected to a vehicle socket via lead wires) has the following problems.

[0006] First, during installation, the lead wires must ultimately be placed inside the cover of the indoor lamp, which presents a risk that the lead wires could be unintentionally pinched and broken.

[0007] Secondly, the circuit board equipped with numerous LED chips is fixed inside the cover of the indoor lamp with double-sided tape, etc. Over time, this fixation can come loose, causing unpleasant noises and causing the light to be tilted.

[0008] The present invention has been made to solve these problems, and its objective is to provide an LED conversion kit for vehicle interior lamps that does not use lead wires that are prone to breakage and that can securely fix an LED board inside the cover of the vehicle interior lamp. [Means for solving the problem]

[0009] In order to solve the above problems, the present invention provides a socket side base to be attached to a socket of a vehicle interior lamp, an LED substrate on which an LED chip is arranged, but The socket side base is configured to be separable, and includes a base part that utilizes a base part used in a light bulb of a vehicle interior lamp as is or is configured in a shape corresponding to the base part, a first board support body that is arranged outside the base part and is electrically connected to the positive side of the base part and has a screw hole, a second board support body that is arranged outside the base part and is electrically connected to the negative side of the base part and has a screw hole, and a connection part that connects and fixes the first and second board supports to the base part, and the LED board has a set of two through holes provided at positions corresponding to the two screw holes, and an exposed part that is electrically connected to the LED chip and is not insulated is formed around the two through holes, and two screws are passed through the two through holes and then screwed into the screw holes. If By doing so, the LED chip and the base portion are electrically connected and fixed at the same time.

[0010] Or, a socket side base to be attached to the socket of a vehicle interior lamp and an LED board on which an LED chip is arranged. but The socket side base is configured to be separable, and includes a base part that utilizes a base part used in a light bulb of a vehicle interior lamp as is or is configured in a shape corresponding to the base part, a first board support body that is arranged outside the base part and is electrically connected to the positive side of the base part and has a screw part, a second board support body that is arranged outside the base part and is electrically connected to the negative side of the base part and has a screw part, and a connection part that connects and fixes the first and second board supports to the base part, and the LED board has a set of two through holes provided at positions corresponding to the two screw parts, and exposed parts that are electrically connected to the LED chip and are not insulated are formed around the two through holes, and the two screw parts are passed through the two through holes and nuts are screwed onto the screw parts. If By doing so, the LED chip and the base portion are electrically connected and fixed at the same time.

[0011] By adopting such a configuration, the LED board can be reliably fixed inside the cover of the vehicle interior lamp without using lead wires that may break. In other words, the socket side base and the LED board are configured to be separable, and the electrical connection and fixation of the board are achieved by utilizing the conductivity of the board support body having the screw and the screw hole (or the board support body and nut having the screw). This makes it unnecessary to use lead wires that may break, and the LED board can be reliably fixed inside the cover of the vehicle interior lamp. In this specification, the term "vehicle interior lamp" includes not only lamps installed in a space where people are riding, such as room lamps and map lamps, but also luggage lamps installed in the luggage compartment.

[0012] Furthermore, the through holes each consisting of two holes provided in one set on the LED substrate may be provided in a plurality of sets at different positions on the LED substrate.

[0013] By adopting such a configuration, it becomes possible to change the position of the LED board.

[0014] It is also preferable that the exposed portions of the LED substrate are provided on both sides of the substrate.

[0015] By adopting such a configuration, the electrical connection between the LED substrate and the substrate support can be made more reliable. Effect of the Invention

[0016] By applying the present invention, it is possible to provide an LED conversion kit for vehicle interior lamps that does not use lead wires that are prone to breakage and that can securely fix an LED board inside the cover of the vehicle interior lamp. [Brief description of the drawings]

[0018] Below, an LED conversion kit 100 for vehicle interior lamps, which is an example of an embodiment of the present invention, will be described with reference to the attached drawings. Note that in order to make the drawings easier to understand, some parts are exaggerated in size and dimensions, and some parts do not necessarily match the actual product. In addition, each drawing should be viewed in the direction of the symbols, and the directions are expressed as up, down, left, right, front, and back based on the directions.

[0019] <Components of LED conversion kit for vehicle interior lamps> As shown in Fig. 1, an LED conversion kit 100 for vehicle interior lamps shown as an example of an embodiment of the present invention is mainly composed of an LED substrate 110 on which an LED chip 112 is arranged, and a socket side base 120 that is attached to a socket 16 (not shown in Fig. 1) of the vehicle interior lamp. The LED substrate 110 and the socket side base 120 are configured to be attached and detached using two screws 130 (only one is shown in Fig. 1).

[0020] The LED substrate 110 is formed in a rectangular shape, and a number of LED chips 112 are arranged in an aligned manner on the substrate. A total of three sets of two through holes 114 are provided at different positions in the longitudinal direction of the substrate. Around each of the through holes 114, exposed portions 116 are provided that are electrically connected to the LED chips 112 and that are not subjected to insulation treatment (the exposed portions 116 are provided in the same manner on both sides of the substrate).

[0021] The exposed portions 116 provided around the through holes 114, which make up a set of two, are designed so that one functions as a positive side and the other as a negative side, and are electrically connected to the multiple LED chips 112 by a pattern (not shown) on the substrate. In other words, when a predetermined power is applied to the two exposed portions 116, the LED chips 112 are configured to emit light.

[0022] The socket side base 120 is composed of a base portion 122, a connection board (connection portion) 124, and a first board support 126 and a second board support 128 that are erected on the connection board 124.

[0023] The base part 122 is made by directly using the base parts used in the bulbs of vehicle interior lamps, or is configured with a shape equivalent to that base part, and can be attached to the socket 16 of the vehicle interior lamp in the same way as an original bulb.

[0024] In this embodiment, the connection board (connection section) 124 is configured using a printed circuit board, and a part of it is inserted into the base section 122 and fixed therein. On the connection board 124, two cylindrical first and second board supports 126 and 128 are erected, and screw holes 126a and 128a are formed in the center of the top surfaces 126b and 128b, respectively. The first and second board supports 126 and 128 are both made of conductive metal, and are electrically connected to the two electrodes of the base section 122 by a pattern (pattern of the printed circuit board) provided on the connection board 124. That is, one electrode of the base section 122 is electrically connected to the first board support 126 via the connection board 124, and the other electrode of the base section 122 is electrically connected to the second board support 128 via the connection board 124.

[0025] The two screws 130 are passed through the set of two through holes 114 formed in the LED substrate 110, and then screwed into the screw holes 126a, 128a formed in the first substrate support 126 and the second substrate support 128. If As a result, the LED substrate 110 is fixed to the socket-side base 120 and is electrically connected (conductive).

[0026] How to install the LED interior lamp kit Next, a method for installing the LED conversion kit 100 for vehicle interior lamps will be described with reference to Figures 2 to 6. Note that the shapes and configurations of the vehicle interior lamps shown in Figures 2 to 6 are merely examples, and it should be noted that the vehicle interior lamps are not limited to the shapes and configurations shown in the figures.

[0027] First, the cover 12 is removed from the vehicle interior lamp body 10 installed in the vehicle to expose the storage section 14, and the original bulb (not shown) installed in the socket 16 is removed from the socket 16 (FIGS. 2 and 3).

[0028] Next, the base portion 122 of the socket side base 120 is attached to the socket 16. At this time, the screw holes 126a, 128a formed in the first board support 126 and the second board support 128 are adjusted so as to face the removed cover side (front side) (FIG. 4).

[0029] After the socket-side base 120 has been attached to the socket 16, the LED board 110 is placed in front of the socket-side base 120, and the position of the through hole 114 formed in the LED board 110 is aligned with the positions of the screw holes 126a, 128a formed in the first board support 126 and the second board support 128, and then the two screws 130 are screwed in. If As a result, the LED board 110 is fixed integrally with the socket side base 120, and at the same time, the two are electrically connected to each other (FIG. 5).

[0030] If necessary, turn the switch on and off to check that the light is on, then attach the cover 12 to complete the installation (replacement) work (Figure 6).

[0031] As described above, the present invention provides a socket-side base 120 to be attached to the socket 16 of a vehicle interior lamp, an LED substrate 120 on which an LED chip 112 is arranged, and butThe socket side base 120 is configured to be separable, and includes a base part 122 that utilizes a base part used in a light bulb of a vehicle interior lamp as is or is configured in a shape corresponding to the base part, a first board support 126 that is arranged outside the base part 122 and is electrically connected to the positive side (or negative side) of the base part 122 and has a screw hole 126a, and a second board support 126 that is arranged outside the base part 122 and is electrically connected to the negative side (or positive side) of the base part 122 and has a screw hole 128a. The LED substrate 110 includes a support 128 and a connection portion (connection substrate) 124 that connects and fixes the first and second substrate supports 126, 128 and the base portion 122. The LED substrate 110 has a set of two through holes 114 provided at positions corresponding to the two screw holes 126a, 128a. An exposed portion 116 that is electrically connected to the LED chip 112 and is not insulated is formed around the two through holes 144. Two screws 130 are passed through the two through holes 144 and then screwed into the screw holes 126a, 128a. If By this, the LED chip 112 and the base portion 122 are electrically connected and fixed at the same time.

[0032] By adopting such a configuration, the LED board 110 can be reliably fixed inside the cover 12 of the vehicle interior lamp without using lead wires that may break. In other words, the socket side base 120 and the LED board 110 are configured to be separable, and the electrical connection and board fixing are achieved by utilizing the conductivity of the board supports 126, 128 themselves having the screws 130 and the screw holes 126a, 128a. This eliminates the need to use lead wires that may break, and allows the LED board to be reliably fixed inside the cover of the vehicle interior lamp.

[0033] Furthermore, the through holes 114, each of which is a set of two, are provided in the LED substrate 110 at different positions on the LED substrate 110 in multiple sets.

If In the past, the LED board 110 and the socket side base 120 were fixed and electrically connected by this. However, for example, a screw may be provided on the top surface of the board support and a nut may be screwed in. If It is also possible to adopt a method of fixing the LED chip to the socket side base that is attached to the socket of the vehicle interior lamp. but The socket side base is configured to be separable, and includes a base part that utilizes a base part used in a light bulb of a vehicle interior lamp as is or is configured in a shape corresponding to the base part, a first board support body that is arranged outside the base part and is electrically connected to the positive side of the base part and has a screw part, a second board support body that is arranged outside the base part and is electrically connected to the negative side of the base part and has a screw part, and a connection part that connects and fixes the first and second board supports to the base part, and the LED board has a set of two through holes provided at positions corresponding to the two screw parts, and exposed parts that are electrically connected to the LED chip and are not insulated are formed around the two through holes, and the two screw parts are passed through the two through holes and nuts are screwed onto the screw parts. If By doing so, the LED chip and the base portion are electrically connected and fixed at the same time. [Explanation of symbols]
