The illumination device 1 of the present embodiment will be described below, but the technical scope of the present invention is not limited to the embodiment.
The lighting device 1 of the present embodiment includes: the first light source 21; a first lamp housing portion 31 that determines an irradiation range of light irradiated from the first light source 21; a second light source 22 for irradiating light (second light beam B) in the same direction as the first light source 21; and a second lamp housing portion 32 that determines an irradiation range of light (second light beam B) irradiated from the second light source 22 (see fig. 1 to 5).
Here, the first lamp cover portion 31 has a cutout portion 311, and the cutout portion 311 is formed so that the directivity angle (angle α × 2 in fig. 5) of the light (first light ray a) from the first light source 21 is larger than the directivity angle (angle β × 2 in fig. 5) of the portion of the first lamp cover portion 31 where the cutout portion 311 is not formed (see fig. 1 to 5).
According to the lighting device 1 of this aspect, the cutout portion is provided in the first housing portion 31, so that only light in a desired direction can be made a large angle.
The first light source 21 and the first lamp housing portion 31 for determining the irradiation range of the light (first light ray a) irradiated from the first light source 21 in the illumination device 1 of the present embodiment will be described in further detail below with reference to fig. 1 to 5.
In the present embodiment, the first light source 21 is a Light Emitting Diode (LED) (see fig. 1 to 5).
The first light source 21 is a Light Emitting Diode (LED), and thus heat generation of the entire lighting device 1 can be further suppressed. The first light source 21 is not particularly limited, and may be, for example, a halogen lamp, an HID lamp, an incandescent lamp, a quartz lamp, or a small krypton lamp.
The light (first light ray a) emitted from the first light source 21 may be either a flood light type light or a spot light type light.
As for the first type light source 21, the size and shape of the first type light source 21 are not particularly limited. In addition, the hue and color temperature of the light emitted from the first light source 21 are not particularly limited.
The first light source 21 is not necessarily composed of a single light source, and may be composed of an aggregate of two or more light sources. Examples of the light source composed of an aggregate of two or more light sources include a light source composed of an aggregate of light emitting diodes of R (red), G (green), and B (blue).
The illumination device 1 of the present embodiment includes three first-type light sources 21 (fig. 1 to 5). However, the number of the first light sources 21 is not limited, and for example, it may be a mode in which two or more first light sources 21 are preferably provided, and three or more first light sources 21 are more preferably provided.
By providing the first light source 21 having the lower limit or more, the box-shaped space can be efficiently illuminated.
Next, the first cap portion 31 will be described with reference to fig. 1 to 5.
As shown in fig. 1 to 5, the first lamp housing portion 31 defines an irradiation range of light irradiated from the first light source 21.
The first cover portion 31 has a cutout 311 on a surface facing the second cover portion 32.
By providing the cutout 311 on the surface facing the second cover portion 32 side, the irradiation range of light can be determined more reliably.
In the present embodiment, the first cap portion 31 has a tapered shape that gradually decreases in diameter toward the light source (see fig. 1 to 5). By making the first cap portion 31 tapered, the irradiation range of light emitted from the first light source 21 can be determined more reliably.
In the present embodiment, the inclination of the first cover portion 31 is gentle at the portion where the cutout 311 is not formed, relative to the portion where the cutout 311 is not formed. In this way, the angle of directivity of light from the first light source 21 can be made larger more easily than in the portion of the first lamp cover portion 31 where the cutout portion 311 is not formed (see fig. 1 to 5).
In the present embodiment, the pointing angle of the light from the first light source 21 (angle α × 2 in fig. 5) determined by the notch portion 311 is 120 °.
Here, the directivity angle is a value 2 times the angle (angle α or β in fig. 5) of 1/2 brightness, which is the brightness of the central axis (first optical axis a' in fig. 5) of the most intense light emission.
However, the pointing angle of the light from the first light source 21 (angle α × 2 in fig. 5) determined by the notch portion 311 is preferably 90 ° or more, more preferably 100 ° or more, further preferably 110 ° or more, and particularly preferably 115 ° or more.
By setting the pointing angle of the light from the first light source 21 (angle α × 2 in fig. 5) determined by the notch portion 311 to be equal to or greater than the lower limit, the box-shaped space can be efficiently illuminated.
The pointing angle of the light from the first light source 21 (angle α × 2 in fig. 5) determined by the notch 311 is preferably 150 ° or less, more preferably 140 ° or less, further preferably 130 ° or less, and particularly preferably 125 ° or less.
By setting the pointing angle of light from the first light source 21 (angle α × 2 in fig. 5) determined by the cutout 311 to be equal to or smaller than the upper limit, the box-shaped space can be efficiently illuminated when the lighting device 1 is installed in the box-shaped space such as the trunk of the truck.
In addition, in the present embodiment, the directivity angle of the light from the first type light source 21 (angle β × 2 in fig. 5) determined by the first lamp cover portion 31 in the portion where the cutout portion 311 is not formed is 45 °.
Here, the angle of directivity of light from the first light source 21 (angle β × 2 in fig. 5) determined by the first lamp cover portion 31 in the portion where the cutout portion 311 is not formed is preferably 30 ° or more, more preferably 35 ° or more, and further preferably 40 ° or more.
By setting the pointing angle of light from the first type light source 21 (angle β × 2 in fig. 5) determined by the first lamp cover portion 31 at a portion where the cutout portion 311 is not formed to be equal to or greater than the lower limit, the box-shaped space can be efficiently illuminated.
The angle of directivity of light from the first light source 21 (angle β × 2 in fig. 5) determined by the first lamp cover portion 31 in the portion where the cutout portion 311 is not formed is preferably 75 ° or less, more preferably 60 ° or less, and still more preferably 50 ° or less.
By setting the directivity angle of the light from the first type light source 21 determined by the first lamp cover portion 31 in the portion where the cutout portion 311 is not formed to be equal to or smaller than the upper limit, when the lighting device 1 is installed in a box-shaped space such as a cargo box of a truck, the light from the first type light source 21 does not irradiate the wall surface of the box-shaped space more than necessary, and therefore, the reflected light on the wall surface can be reduced.
The shape, size, and the like of the cutout 311 are not limited as long as the cutout is formed so that the angle of directivity of the light from the first light source 21 (angle α in fig. 5 × 2) is larger than the angle of directivity of the light in the first lamp housing portion 31 (angle β in fig. 5 × 2) in which the cutout 311 is not formed.
The shape, material, size, and the like of the first lamp cover portion 31 are not particularly limited.
Next, the second light source 22 and the second lamp housing portion 32 that determines the irradiation range of light emitted from the second light source 22 in the lighting device 1 of the present embodiment will be described in further detail with reference to fig. 1 to 5.
In the present embodiment, the second light source 22 is a Light Emitting Diode (LED) (see fig. 1 to 5). By using the light sources 22 of the second type as Light Emitting Diodes (LEDs), heat generation of the entire lighting device 1 can be further suppressed.
However, the kind of the second light source 22 is not particularly limited, and may be, for example, a halogen lamp, an HID lamp, an incandescent lamp, a quartz lamp, a compact krypton lamp.
The light (second light B) emitted from the second light source 22 may be either a flood light or a spot light.
As for the second light source 22, the size and shape of the second light source 22 are not particularly limited. The hue and color temperature of the light emitted from the second light source 22 are not particularly limited.
The second light source 22 is not necessarily composed of a single light source, and may be composed of an aggregate of two or more light sources. Examples of the light source composed of an aggregate of two or more light sources include a light source composed of an aggregate of three-color light emitting diodes of R (red), G (green), and B (blue).
The lighting device 1 of the present embodiment includes three second-type light sources 22. However, the number of the second light sources 22 is not limited, and for example, two or more second light sources 22 may be provided. By providing two or more second light sources 22, the box-shaped space can be efficiently illuminated.
Here, in the case of the system including two or more first light sources 21 and second light sources 22, the row of the first light sources 21 and the row of the second light sources 22 are preferably substantially parallel to each other.
By making the row of the first light sources 21 substantially parallel to the row of the second light sources 22, the box-shaped space can be efficiently illuminated.
Here, in the case of the system including two or more first light sources 21 and second light sources 22, the substrate 2 in which the rows of the first light sources 21 are arranged substantially in parallel with the rows of the second light sources 22 may be used. The substrate 2 is preferably a PCB substrate.
Next, the second cap portion 32 will be described with reference to fig. 1 to 5.
As shown in fig. 1 to 5, the second lamp housing portion 32 determines the irradiation range of the light (second light ray B) irradiated from the second light source 22.
In the present embodiment, the second cap portion 32 has a tapered shape that gradually decreases in diameter toward the light source (see fig. 1 to 5). The second lamp housing portion 32 has a tapered shape, so that the irradiation range of the light emitted from the second light source 22 can be determined.
In the present embodiment, the second lamp housing portion 32 is configured such that the pointing angle (angle × 2 of γ in fig. 5) of the light (second light ray B) irradiated from the second light source 22 is 45 °.
Here, the directivity angle is a value 2 times the angle (angle γ in fig. 5) of 1/2 brightness, which is the brightness of the central axis (second optical axis B' in fig. 5) of the most intense light emission.
However, the pointing angle of the light (second light ray B) irradiated from the two light sources determined by the second lamp cover portion 32 is not particularly limited, and is preferably 30 ° or more, more preferably 35 ° or more, and further preferably 40 ° or more.
By setting the pointing angle of the light (second light ray B) emitted from the two light sources determined by the second cover part 32 to the above range, the box-shaped space can be efficiently illuminated.
The directivity angle of the light (second light ray B) emitted from the two light sources determined by the second lamp cover portion 32 is preferably 75 ° or less, more preferably 60 ° or less, and still more preferably 50 ° or less.
By setting the directivity angle of the light (second light beam B) emitted from the two light sources determined by the second lamp cover portion 32 to the above range, when the lighting device 1 is installed in the box-shaped space, the light from the second light source 22 does not irradiate the wall surface of the box-shaped space more than necessary, and therefore, the reflected light can be reduced.
The shape, material, size, and the like of the second lamp housing portion 32 are not particularly limited.
Here, the illumination device plate 3 including the first cap portion 31 and the second cap portion 32 can be used in the illumination device 1 of the present invention.
Preferably, the lighting device plate 3 has a structure in which the first lamp housing portion 31 and the second lamp housing portion 32 are formed so as to correspond to the arrangement of the first light source 21 and the second light source 22 of the lighting device 1 (see fig. 1 to 5).
Next, the range of light emitted by the illumination device 1 of the present invention will be described with reference to fig. 1 to 5.
As shown in fig. 1 to 5, the first lamp housing portion 31 is configured to determine an irradiation range of light (first light ray a) irradiated from the first light source 21. Here, since the first lamp cover portion 31 has the cutout portion 311, the light (the first light ray a) from the first light source 21 is blocked by the first lamp cover portion 31 in the direction in which the cutout portion 311 is not formed in the first lamp cover portion 31, and the pointing angle of the light (the first light ray a) is restricted, while the restriction of the pointing angle generated by the first lamp cover portion 31 is small in the direction in which the cutout portion 311 is formed.
Therefore, the portion where the cutout portion 311 is formed makes the angle of directivity of the light (first light ray a) from the first light source 21 larger than that of the portion where the cutout portion 311 is not formed.
Therefore, since the second light source 22 whose irradiation range of light (the second light ray B) is determined by the second lamp housing portion 32 is also provided, the lighting device 1 having a unique irradiation range in which the light (the first light ray a) from the first light source 21 is irradiated over a wider range and the light (the second light ray B) from the second light source 22 is irradiated over a limited pointing angle than the first light source 21 is obtained.
A more preferred embodiment of the lighting device 1 of the present embodiment will be described below.
The lighting device 1 of the present embodiment includes the translucent cover 4 having the curved surface 41. The curved surface 41 of the light-transmitting cover 4 is formed on the notched portion 311 side.
In the illumination device 1 of this embodiment, since the light beams (the first light beam a and the second light beam B) emitted from the first light source 21 and the second light source 22 are not blocked, the entire illumination device 1 can be designed to be smaller (see fig. 1 to 5).
Here, the material, size, and shape of the translucent cover 4 are not limited as long as it has translucency. The material of the light-transmitting cover 4 may be, for example, polycarbonate.
In addition, "having light transmittance" in the present specification means a property of being capable of transmitting light. In the present specification, the "light-transmissive cover 4" includes two meanings: a wall comprising a translucent material, and a wall comprising a transparent material.
The lighting device 1 of the present embodiment includes a heat dissipation portion 6. The second light source 22 is provided with the heat dissipation portion 6, and thus heat generation of the entire lighting device 1 can be further suppressed.
Further, the present invention is more preferably an embodiment including a mounting member 5 having a hole.
Further, by providing the mounting member 5 having the hole, the mounting member can be more easily mounted on the upper surface side portion of the box-shaped space such as the bed of the truck.
Further, in the present embodiment, the lighting device 1 is formed by combining different components. However, the lighting device 1 of the present invention may be formed by integrally molding a plurality of members as needed.
