DETAILED DESCRIPTION OF THE INVENTION

[0012] (Overall composition) An embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a front view of a portable emergency light 10 of this embodiment, Fig. 2 is a cross-sectional view of the portable emergency light 10 along axis X, and Fig. 3 is a perspective view of the portable emergency light 10. The portable emergency light 10 includes a rod-shaped red light-emitting unit (second light-emitting unit) 40, a white light-emitting unit 30, and a handle unit 20 to which the red light-emitting unit 40 is connected at one end and the white light-emitting unit 30 is connected at the other end. The red light-emitting unit 40, the handle unit 20, and the white light-emitting unit 30 are coaxially connected in this order. The length direction of the portable emergency light 10 is parallel to the direction in which axis X extends.

[0013] (Handle part 20) The handle unit 20 includes a cylindrical handle main body 21 and a switch 22. The handle main body 21 includes a first portion 23 and an second portion 24. The switch 22 is provided on an outer peripheral surface 23a of the first portion 23 of the handle main body 21. The second portion 24 is a portion to be gripped by the hand of the user U, and has a smaller outer diameter and a longer length than the first portion 23. The first portion 23 and the second portion 24 may be integrally formed or may be made of different materials. In this embodiment, the first portion 23 and the second portion 24 are made of different materials, and one end of the second portion 24 is fitted into the other end of the first portion 23 to be connected. Stops 25a, 25b (FIG. 2) are provided on the other edge of the first portion 23 and the outer peripheral surface 24a of one end of the second portion 24, respectively, to restrict insertion of the second portion 24 into the first portion 23.

[0014] 3, an attachment portion 26 for attaching, for example, a strap for preventing dropping is provided on the outer peripheral surface 24a of the other side portion 24 of the handle main body 21. In this embodiment, the attachment portion 26 is a plate-like member with a through-hole formed therein. However, the attachment portion 26 is not limited to this, and may have any configuration to which a strap can be attached, such as a clip made of an elastic member.

[0015] 2, the hollow interior of handle main body 21 is provided with switch section 27, which houses a switch circuit (not shown), on one side, and power supply section 28, which houses power supply 28a for driving red light emitter 40 and white light emitter 30, on the other side. Second cover main body 43a of red light emitter 40 is connected to the opening at one end of switch section 27.

[0016] The switch circuit of the switch section 27 is connected to the switch 22, the red light emitting section 40 and the white light emitting section 30, and controls the turning on and off of the red light emitting section 40 and the white light emitting section 30.

[0017] A switch 22 is provided on the outer peripheral surface 23a of one side portion 23 of the handle main body 21 at a position corresponding to the switch unit 27. In this embodiment, the switch 22 is a push button type, but any type of switch 22 may be used. The switch 22 controls the driving of the red light-emitting unit 40 and the white light-emitting unit 30, i.e., turning them on, blinking, and off. For example, each time the user U presses the switch 22, the red light-emitting unit 40 and the white light-emitting unit 30 are switched among the following five states.

[0018] First state: red light emitting unit 40 is lit, white light emitting unit 30 is off Second state: the red light emitting section 40 flashes, and the white light emitting section 30 is off Third state: red light emitting section 40 is lit, white light emitting section 30 is lit Fourth state: the red light emitting section 40 flashes, and the white light emitting section 30 lights up Fifth state: red light emitting unit 40 is off, white light emitting unit 30 is off

[0019] Alternatively, five switches 22 may be provided, with five states assigned to each switch 22. In this case, the states of the red light-emitting unit 40 and the white light-emitting unit 30 are switched by pressing each switch 22. Alternatively, two switches 22 may be provided. The two switches are a switch for switching the white light-emitting unit 30 between on and off, and a switch for switching the red light-emitting unit 40 between on, flashing, and off. The switch for the white light-emitting unit 30 may be provided on the outer peripheral surface 24a of the other side portion 24 of the handle main body 21, near a connecting member 34 (described below) that connects the white light-emitting unit 30 and the handle main body 21. The switch for the red light-emitting unit 40 may be provided in the same location as the switch 22 in FIG. 1.

[0020] Furthermore, the portable guide light 10 does not need to perform all of the first to fifth states, but only needs to perform at least the third or fourth state in which the white light emitting unit 30 is lit, and the fifth state. Furthermore, the white light emitting unit 30 may flash.

[0021] The power supply unit 28 on the other side of the handle body 21 houses a power supply 28a, such as a dry cell, connected in series.

[0022] The length of the handle body 21 in the longitudinal direction is set to, for example, 220 mm, and the length of the other side portion 24 that is gripped by the user U in the longitudinal direction is set to, for example, 140 mm.

[0023] (white light emitting unit 30) A white light emitting unit 30 is connected to the other end of the handle body 21. The white light emitting unit 30 emits white light outward. Note that "white" refers to light that is not biased toward a specific hue in the visible light range and contains multiple wavelength components, and is perceived as white overall, and refers to light that has chromaticity coordinates near the white point on the CIE 1931 chromaticity diagram, or light with a correlated color temperature in the range of approximately 2500K to 10000K.

[0024] The white light-emitting unit 30 has a first substrate 31, a first light-emitting source 32 provided on the first substrate 31, and a first cover 33. The first substrate 31 is provided at the other end of the other-side portion 24 of the handle main body 21, parallel to a plane perpendicular to the longitudinal direction. The first light-emitting source 32 is provided on the outer surface (other side) of the first substrate 31. One or more first light-emitting sources 32 may be provided on the first substrate 31.

[0025] The first cover 33 covers the first light source 32 and is attached to the other end of the other part 24 of the handle body 21 by an annular connecting member 34. The first cover 33 is substantially hemispherical and is attached so that it is convex outward. The shape of the first cover 33 is not limited, and any shape may be used as long as it can cover the first light source 32.

[0026] The first cover 33 is formed from a material that is a resin composition in which a pigment is dispersed in a synthetic resin. Examples of the synthetic resin that can be used include polycarbonate resin, acrylic resin, and silicone resin. Examples of the pigment that can be used include titanium oxide (TiO2), silica (SiO2), and alumina (Al2O3). By dispersing these pigments in the synthetic resin, the light from the first light source 32 that passes through the first cover 33 is scattered, thereby achieving desired diffusion characteristics.

[0027] The ratio of pigment to synthetic resin is preferably 10% or more and 50% or less, and more preferably 20% or more and 30% or less. The higher the ratio of pigment in first cover 33, the more diffused the light emitted from first light source 32, but on the other hand, first cover 33 becomes less able to transmit light, resulting in lower luminance (brightness) of the light. Therefore, the ratio of pigment is determined by balancing the light diffusion performance and transmittance.

[0028] The white light emitting unit 30 only needs to emit white light when viewed from the outside. The first light source 32 only needs to be a light source that emits white light, and may be, for example, a white light emitting diode (white LED). It may also be a fluorescent lamp. The first cover 33 becomes white by containing a pigment.

[0029] The length of the first cover 33 in the longitudinal direction is, for example, 22 mm.

[0030] (Red light emitting unit (second light emitting unit) 40) The second light-emitting unit is a rod-shaped light-emitting unit, and in this embodiment, emits red light outward. In the following description, it will also be referred to as the "red light-emitting unit 40." "Red" refers to light that mainly contains long-wavelength components in the visible light range, with a dominant wavelength in the range of approximately 600 to 700 nm, or light that has chromaticity coordinates in the red range on the CIE 1931 chromaticity diagram.

[0031] The red light-emitting unit 40 includes a cylindrical second cover 43, a second substrate 41 provided inside the second cover 43, and a plurality of second light sources 42 provided on the second substrate 41. The second substrate 41 extends over the entire length of the second cover 43, and the plurality of second light sources 42 are arranged in a row at equal intervals on the second substrate 41. The number of rows, arrangement, and quantity of the second light sources 42 are appropriately determined depending on the luminance (brightness) required for the red light-emitting unit 40. Alternatively, a transparent case having a plurality of cavities may be used instead of the second substrate 41. In this case, a second light source 42 is housed in each cavity, and the transparent case is housed within the second cover 43. Alternatively, the transparent case and the second cover 43 may be integrally formed.

[0032] The second cover 43 is made of synthetic resin and includes a cylindrical second cover body 43a and a tip cap 43b that closes an opening at one end of the second cover body 43a. The other end of the second cover body 43a is connected to the handle 20. The length of the second cover body 43a is, for example, 335 mm or 175 mm, the length of the tip cap 43b is, for example, 10 mm, and the outer diameter of the second cover body 43a is, for example, 30 mm.

[0033] The red light-emitting unit 40 only needs to emit red light when viewed from the outside. The second light source 42 is a light source that emits red light, for example, a red light-emitting diode (red LED). In this case, the second cover main body 43a and the tip cap 43b of the second cover 43 are opaque and may be colored white or red. The second cover 43 may also be transparent.

[0034] The second light source 42 may also be a light source that does not emit red light, for example, a light source that emits white light. In this case, the second cover body 43a and the tip cap 43b of the second cover 43 are colored red. A red film may also be attached to the second cover body 43a and the tip cap 43b of the second cover 43.

[0035] In this embodiment, the second light-emitting section is a red light-emitting section that emits red light, but the second light-emitting section may be a blue light-emitting section that emits blue light, or a green light-emitting section that emits green light. "Blue" refers to a color perceived as having light with a wavelength of approximately 450 nm or more and 495 nm or less as the main component in the visible light range. "Green" refers to a color perceived as having light with a wavelength of approximately 495 nm or more and 570 nm or less as the main component in the visible light range.

[0036] (use) As shown in FIG. 4, the user U grips the other side portion 24 of the handle portion 20 with the white light-emitting unit 30 of the portable emergency light 10 facing the user U. The user U presses the switch 22 to switch the operation of the white light-emitting unit 30 and the red light-emitting unit 40 between states 1 to 5. In states 3 and 4, the white light-emitting unit 30 is turned on, and the light emitted by the white light-emitting unit 30 illuminates the user U, allowing viewers such as vehicle drivers to see the user U. The white light-emitting unit 30 emits white light, which contains a wider wavelength of visible light than red light, making it easier for viewers to see the user U than red light.

[0037] Furthermore, because the first cover 33 of the white light-emitting unit 30 contains a pigment, the light emitted by the first light source 32 is diffused as it passes through the first cover 33. When the first cover 33 does not contain a pigment or when the first cover 33 is not provided, the light emitted by the white light-emitting unit 30 is more directional and brighter than when the first cover 33 contains a pigment. This light only illuminates a portion of the user U, making it difficult for the viewer to see the user U. Furthermore, the viewer finds the light dazzling, making it difficult for the viewer to see the user U. However, according to this embodiment, the light emitted by the first light source 32 is diffused as it passes through the first cover 33, so it can illuminate a wider area of ​​the user U, making it easier for the viewer to see the user U.

[0038] While one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment and various modifications are possible without departing from the spirit and scope of the present invention. The dimensions, materials, shapes, and relative positions of components described as an embodiment or shown in the drawings are merely illustrative examples and are not intended to limit the scope of the present invention. The terms "comprise" and "include" a component are not exclusive expressions that exclude the presence of other components. "Parallel" and "orthogonal" mean essentially "parallel" and "orthogonal," and include not only the strict "parallel" and "orthogonal" states but also an error of a few degrees. In addition, expressions such as "end" and "portion" are sometimes used. For example, "end" means a portion having a certain range that includes the "end." The same applies to other expressions that include "portion." [Explanation of symbols]
