Description

The present invention relates to a lighting device including a lighting unit and an acoustic unit.

Conventionally, for example, a lighting device including a wireless communication module that constitutes a helical antenna by an antenna pattern formed on a substrate has been disclosed (see, for example, Patent Document 1). This antenna pattern extends in a direction perpendicular to the substrate. In such a lighting device, lighting performance can be ensured and highly reliable wireless communication can be performed.

JP-A-2015-115287

By the way, in such a lighting device, the antenna pattern extends in a direction perpendicular to the substrate. For this reason, for example, in the case of manufacturing a lighting device by assembling each component, the antenna pattern protrudes perpendicularly to the substrate when transporting the member in the state where the antenna pattern and the substrate are integrally assembled. Therefore, there is a risk that the antenna pattern will be damaged by contact with some object. Therefore, it is necessary to protect the antenna pattern with a protective member or the like so that the antenna pattern is not damaged during transportation. As a result, unnecessary costs increase when assembling the parts.

Therefore, it is an object of the present disclosure to provide a lighting device capable of suppressing an increase in manufacturing cost required for assembling the lighting device.

In order to achieve the above object, one aspect of the lighting device according to the present invention holds a second substrate supported in an upright position with respect to the first substrate, the first substrate, and the first substrate. (Ii) A mounting plate for detachably holding the board is provided, the mounting plate has a housing support portion having a storage space into which the second board is inserted, and the housing support portion is associated with the second board. By fitting, the second substrate has an engaging recess that supports the second substrate in a predetermined posture, and the second substrate has a main body portion and an extending portion that engages with the engaging recess, and the predetermined The posture is the first posture in which the main body portion stands upright with respect to the extending portion by engaging the extending portion with the engaging recess, and the extending portion engages with the engaging portion. The second substrate includes a second posture in which the main body portion is in an inverted posture with respect to the extending portion by engaging with the recess and is accommodated in the accommodation space, and the second substrate is the first posture. By being held by the mounting plate in the posture of the above and the second posture, the mounting plate is detachably held by the mounting plate .

Further, a gap is provided between the second light source 122 and the first light guide plate 3 and the second light guide plate 4 so that the second light source 122 and the first light source plate 3 and the second light guide plate 4 do not come into contact with each other. ing.

The first light source 121 and the second light source 122 are so-called SMD (Surface Mount Devices) type LED elements. The SMD type LED element is specifically a package type LED element in which an LED chip (light emitting element) is mounted in a resin-molded cavity and a phosphor-containing resin is enclosed in the cavity. For example, a surface mount type LED element that emits white light by combining a blue LED chip and a yellow phosphor-containing resin is adopted as the first light source 121 and the second light source 122.

The first light source 121 and the second light source 122 are controlled by the lighting control unit 13 to turn on and off. Further, the first light source 121 and the second light source 122 are controlled by the illumination control unit 13 to perform dimming and toning.

The first light source 121 and the second light source 122 are not limited to such a configuration, and a COB (Chip On Board) type module in which an LED chip is directly mounted on the substrate 120 may be used. .. Further, the light emitting element included in the first light source 121 and the second light source 122 is not limited to the LED, and is, for example, a semiconductor light emitting element such as a semiconductor laser, an EL element such as an organic EL (ElectroLuminescence) or an inorganic EL, or the like.

The lens cover 23 is arranged in the light emitting module 21 so as to cover the plurality of first light sources 121. Specifically, when the lens cover 23 and the plurality of first light sources 121 are viewed in a plan view, the individual lenses formed on the lens cover 23 have a one-to-one correspondence with each of the first light sources 121. Each lens of the lens cover 23 controls the light distribution angle of the transmitted light when the light emitted from each of the corresponding first light sources 121 is transmitted.

Further, a notch 231 is provided at each outer end portion of the pair of lens covers 23. Specifically, the lens cover 23 on the Y-axis plus direction side is provided with a notch 231 at the end portion on the Y-axis plus direction side.

These pair of lens covers 23 control the light distribution emitted by the plurality of first light sources 121 to emit light. As a result, the pair of lens covers 23 becomes the light emitting region of the illumination unit 20. Since each of the pair of lens covers 23 is long in the Y-axis direction, the light emitting region is also provided in a long length along the Y-axis direction. As described above, since the pair of speakers 41 and the pair of cover bodies 42 are arranged so as to sandwich the illumination unit 20 in the Y-axis direction, the pair of speakers 41 and the light emitting region have a plan view of the light emitting region. If you do, they do not overlap.
