Description

[Technical field]

[0001] The present disclosure relates to a lighting device including an appliance and a lamp. [Background technology]

[0002] Conventionally, lighting devices comprising a fixture and a lamp have been known. Here, several techniques have been proposed for making wiring easier by tilting the mounting direction of the lamp relative to the fixture when wiring the lighting device. Patent Document 1 discloses a lighting fixture comprising a fixture body to be attached to a construction material and a light source unit to be detachably attached to the fixture body. In Patent Document 1, a locking metal fitting provided on the light source unit is slid from a normal position and inserted into an insertion hole of a recess formed in the fixture body, whereby the light source unit is temporarily held in a state tilted by approximately 90°.

[0003] Patent Document 2 discloses an attachment device for a lighting device that includes a fixture body having a light source unit attachment portion and a light source unit that is detachably attached to the light source unit attachment portion. In Patent Document 2, the fixture side attachment portion and the unit side attachment portion are connected by inserting either of the attachment portions into an opening formed in either of the fixture side attachment portion or the unit side attachment portion. In addition, Patent Document 1 discloses that when the light source unit is tilted, the tilted attitude of the light source unit is maintained by inserting either of the attachment portions into an opening formed in either of the fixture side attachment portion or the unit side attachment portion. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 6021010 [Patent Document 2] Patent No. 6956556 Summary of the Invention [Problem to be solved by the invention]

[0005] However, the lighting device disclosed in Patent Document 1 requires the locking fitting to be slid from its normal position beforehand in order to temporarily hold the luminaire in a tilted state, which is time-consuming. Also, the length of the opening of the mounting device for the lighting fixture disclosed in Patent Document 2 is short, so the range in which the luminaire, which is the light source unit, can be tilted is narrow.

[0006] The present disclosure has been made to solve the above-mentioned problems, and provides a lighting device that expands the range in which a lamp can be tilted without hassle. [Means for solving the problem]

[0007] The lighting device disclosed herein comprises a fixture provided on an attachment portion and having a fixture side connector; a base portion and a lamp side connector provided on the base portion and engaging with the fixture side connector, the lamp being attached to the fixture by engagement between the fixture side connector and the lamp side connector, the lamp side connector having a lamp side body placed on the base portion and having an opening upper portion through which the fixture side connector is inserted horizontally, and an opening side portion connected to the opening upper portion, through which the fixture side connector is inserted at an angle and which together with the opening upper portion is longer than the width of the fixture side connector. Effect of the Invention

[0008] According to the present disclosure, an upper opening and a side opening are formed in the lamp side connector. The lamp is attached in a normal position by inserting the fixture side connector into the upper opening, and the fixture side connector moves to the side opening, so that the lamp gradually tilts. In this way, the attitude (tilt angle) of the lamp can be changed without performing any work in advance, so that no effort is required. In addition, the side opening combined with the upper opening is longer than the width of the fixture side connector. This expands the range of angles at which the lamp can tilt. Therefore, the present disclosure has the effect of expanding the range of angles at which the lamp can tilt without any effort. [Brief description of the drawings]

[0020] (Cover 23) The cover 23 is attached to the base portion 21 and covers the light source portion 22. The cover 23 is, for example, a resin member that diffuses the light irradiated from the light source portion 22. The cover 23 has a cover main body portion 23a that extends in the longitudinal direction and covers the entire surface of the light source portion 22, and cover end portions 23b that are provided at both ends of the cover main body portion 23a and serve as lids for the cover main body portion 23a.

[0021] (Power supply section 24) The power supply unit 24 is attached to the other surface of the base unit 21 and converts the power supplied from an external power source to light the light source unit 22 .

[0022] (Lamp side connector 25) FIG. 5 is a perspective view showing the lamp side coupler 25 according to the first embodiment. FIG. 6 is a front view showing the lamp side coupler 25 according to the first embodiment, and FIG. 7 is a top view showing the lamp side coupler 25 according to the first embodiment. FIG. 8 is a side view showing the lamp side coupler 25 according to the first embodiment, and FIG. 9 is a side cross-sectional view showing the lamp side coupler 25 according to the first embodiment. As shown in FIG. 4, the lamp side coupler 25 is attached to the other surface of the base portion 21, and is a spring receiving metal fitting on which the fixture side coupler 16 of the fixture 10 is hooked. The lamp 20 is attached to the fixture 10 by hooking the fixture side coupler 16 to the lamp side coupler 25. As shown in FIGS. 5 to 9, the lamp side coupler 25 has a leg portion 26, a side portion 27, a lamp side main body 28, and an attachment portion 29.

[0023] (leg 26) The legs 26 are placed on the other surface of the base portion 21 and are a pair of rectangular plate-like members.

[0024] (Side 27) The side portions 27 are a pair of rectangular plate-like members that stand upright from the opposing sides of the pair of legs 26. Only one of the four corners of the side portions 27 is cut out.

[0025] (Light fixture body 28) The lamp side body 28 is a plate-like member that connects the opposing sides of the side parts 27. The lamp side body 28 is formed with an upper opening 30 and two side opening parts 31. The upper opening 30 is an opening into which the fixture side connector 16 is inserted horizontally, and is formed wide from the center of the upper end part of the lamp side body 28 downward. The side opening parts 31 are openings into which the fixture side connector 16 is inserted in an inclined state, and are formed by extending downward from the lower end parts on both sides of the upper opening 30.

[0026] The outer edge 31a of the opening side 31 is inclined outward from the top to the bottom. The opening side 31 combined with the opening upper part 30 is longer than the width of the fixture side connector 16. That is, the combined length of the outer end of the opening upper part 30 and the outer end of the opening side 31 is longer than the width of the fixture side connector 16. The lamp side body 28 is provided below the center of the opening upper part 30 and has a holding part 32 that holds the fixture side connector 16. That is, the holding part 32 is a part sandwiched between the two opening side parts 31. The height of the lamp side body 28 is lower than the height of the side part 27, and a space into which the mounting part 29 is inserted is formed below the lamp side body 28.

[0027] (Mounting part 29) The mounting portion 29 is a member with an L-shaped cross section, which extends along the lamp side main body 28 after being inserted into the space, and extends beyond the upper end of the lamp side main body 28. A mounting hole 29a is formed in the portion of the mounting portion 29 inserted into the space, and the lamp side connector 25 is attached to the base portion 21 by inserting a screw into the mounting hole 29a and screwing it into the mounting hole 29a.

[0028] (Luver 40) 2, the louver 40 is made up of a plurality of elongated members arranged in parallel, and changes the illumination direction of the lighting device 1. The louver 40 is attached to the fixture 10 so as to be disposed below the lighting fixture 20.

[0029] (Lighting equipment usage status) FIG. 10 is a diagram showing a state in which the lighting device 1 according to the first embodiment is used. The configuration other than the fixture-side connector 16 and the lamp-side connector 25 is omitted from the illustration. Next, the engagement state between the fixture-side connector 16 and the lamp-side connector 25 when the lighting device 1 is used will be described. As shown in FIG. 10, when the lighting device 1 is used, the fixture-side connector 16 is inserted into the opening upper portion 30 of the lamp-side connector 25 from the tip portion 16c side, and the lamp-side connector 25, which is kept horizontal, engages with the curved portion 16b. As a result, the lamp 20 is attached to the fixture 10 while being kept horizontal. At this time, the opening side portion 31 does not interfere with the use of the lighting device 1.

[0030] (Lighting equipment wiring work in progress) FIG. 11 is a diagram showing a wiring work state of the lighting device 1 according to the first embodiment. As in FIG. 10, configurations other than the fixture-side connector 16 and the lamp-side connector 25 are omitted from the illustration. Next, the engagement state between the fixture-side connector 16 and the lamp-side connector 25 when wiring work is performed in the lighting device 1 will be described. As shown in FIG. 11, the tip 16c of the fixture-side connector 16 is inserted from the opening upper portion 30 to the opening side portion 31 of the lamp-side connector 25, and the outer edge portion 31a, which is kept substantially horizontal, and the tip 16c are engaged. As a result, the lighting device 20 is attached to the fixture 10 in a state in which it is tilted at about 90°. The opening side portions 31 extend downward symmetrically from both lower ends of the opening upper portion 30. Therefore, the lighting device 20 can also be attached to the fixture 10 in a state in which it is tilted at about 90° in the opposite direction, so that it can be tilted at about 180° in total.

[0031] Furthermore, the lamp side body 28 has a holding portion 32 that is provided below the center of the opening upper portion 30 and holds the fixture side connector 16. The holding portion 32 is provided at a position sandwiched between two opening side portions 31. The holding portion 32 restricts the movable range of the fixture side connector 16 when it is temporarily held in the wiring work state. In other words, the fluctuation of the tilt angle of the lamp 20 is suppressed. Therefore, the posture of the lamp 20 in the tilted state is stable, making it easier for the worker to perform the wiring work. Furthermore, the outer edge portion 31a of the opening side portion 31 is inclined outward from the top to the bottom. Therefore, when moving from the device use state to the wiring work state, the tip portion 16c of the fixture side connector 16 inserted into the opening upper portion 30 slides smoothly along the outer edge portion 31a of the opening side portion 31. Therefore, the lamp 20 can be tilted smoothly.

[0032] According to the first embodiment, the lamp side connector 25 has an opening upper portion 30 and an opening side portion 31. The lamp side connector 16 is inserted into the opening upper portion 30 to move the lamp 20 from a state in which the lamp 20 is attached in a normal position to the opening side portion 31, so that the lamp 20 gradually tilts. In this way, the attitude (tilt angle) of the lamp 20 can be changed without performing any work in advance, so that no effort is required. In addition, the opening side portion 31 combined with the opening upper portion 30 is longer than the width of the lamp side connector 16. Therefore, the range of angles at which the lamp 20 can tilt is expanded. Therefore, the present disclosure has the effect of expanding the range of angles at which the lamp 20 can be tilted without any effort.

[0033] (First Modification) Fig. 12 is a front view showing the lamp side coupler 25 according to the first modified example. As shown in Fig. 12, the first modified example does not have a holding portion 32. The opening side portion 31 extends entirely below the opening upper portion 30. This allows the lamp 20 to be tilted smoothly. Note that it is also possible to appropriately change the size of the holding portion 32 so that it is larger than the opening side portion 31 of the first embodiment and smaller than the opening side portion 31 of the first modified example.

[0034] (Second Modification) Fig. 13 is a front view showing a lamp side coupler 25 according to a second modified example. In the second modified example, as shown in Fig. 13, the outer edge 31a of the opening side portion 31 extends straight down. In this case, the same effect as in the first embodiment is achieved.

[0035] (Third Modification) 14 is a front view showing a lamp side coupler 25 according to a third modified example. In the third modified example, the outer edge 31a of the opening side 31 is inclined inwardly from above to below. In this case, the same effects as those of the first embodiment are achieved.

[0036] (Fourth Modification) 15 is a front view showing a lamp side connector 25 according to a fourth modified example. In the fourth modified example, the opening side portion 31 extends downward from one lower end of the opening upper portion 30. This is effective when it is necessary to specify the direction in which the lamp 20 is tilted due to restrictions on the location where the lighting device 1 is installed, etc.

[0037] (Fifth Modification) 16 is a front view showing a lamp side connector 25 according to the fifth modified example. In the fifth modified example, the opening side part 31 extends downward from one lower end part of the opening upper part 30, and is formed in a position symmetrical to the opening side part 31 of the fourth modified example. As with the fourth modified example, the fifth modified example is also effective in cases where it is necessary to specify the direction in which the lamp 20 is tilted due to restrictions on the location where the lighting device 1 is installed, etc.

[0038] The lighting device 1 is not limited to the configuration of the first embodiment and its modified examples. The configuration of the first embodiment is an example, and may include other configurations. The lighting device 1 includes the range of design modifications and application variations that are normally implemented by a person skilled in the art, within the scope of the technical concept.
