Abstract
Description
[Technical Field]
[0001] The present invention relates to portable electric lights. [Background technology]
[0002] A portable light is a lighting device that can be carried and used, and is also called a flashlight (including those that are too small to fit in a pocket).
[0003] This type of portable electric lamp is used not only in normal times but also in emergencies, and therefore various lamps with additional functions useful in emergencies have been proposed (see, for example, Patent Document 1). [Prior art documents] [Patent documents]
[0004] [Patent Document 1] Microfilm of Utility Model Application No. 54-056077 (Utility Model Application No. 55-156301) Summary of the Invention [Problem to be solved by the invention]
[0005] Portable electric lights may be used, for example, to illuminate the direction of evacuation when evacuating in the event of a fire or power outage.
[0006] However, if the fire progresses and smoke fills the area, even if a portable light is used to illuminate the evacuation direction, it will be blocked by the smoke and will not improve visibility.
[0007] SUMMARY OF THE INVENTION In view of the above circumstances, an object of the present invention is to provide a portable electric light that can be suitably used to illuminate the direction of evacuation in the event of a fire. [Means for solving the problem]
[0008] This invention is a portable lamp comprising a lamp body in which a light-emitting unit is provided, and a fan provided on the lamp body as a protruding member capable of blowing air in the direction of light emitted by the light-emitting unit.
[0009] In this invention, when used in the event of a fire, the fan may form smoke convection in the space where the fan is used, including a flow of smoke along the direction of the light irradiation. The fan may be provided so as to be movable. The fan may be provided so as to have a variable airflow direction. The fan may be provided with a filter on the intake side. The operating mode may be selectable, and the operating modes may include a first operating mode in which the fan operates with a high airflow rate and a low luminous intensity of the light-emitting unit, and a second operating mode in which the fan operates with a low airflow rate and a high luminous intensity of the light-emitting unit. The operating modes may further include a third operating mode in which the fan operates with a high airflow rate and a high luminous intensity of the light-emitting unit. The lamp body may be provided with an operating mode selection control unit and a guide display unit that guides the user to select the first operating mode when there is a lot of smoke and the second operating mode when there is little smoke. In addition, the airflow rate of the fan and the luminous intensity of the light-emitting unit can be adjusted, and when the airflow rate of the fan is increased, the luminous intensity of the light-emitting unit is automatically decreased, and when the airflow rate of the fan is decreased, the luminous intensity of the light-emitting unit is automatically increased. [Effects of the Invention]
[0010] In this invention, the fan can blow air in the direction of the light emitted by the light-emitting unit. Therefore, when used to illuminate the evacuation direction in the event of a fire or power outage, even if smoke is present, the light can be emitted while moving the smoke forward and eliminating it. In other words, visibility in the evacuation direction can be improved even if smoke is present.
[0011] Therefore, according to the present invention, a portable electric light can be provided that can be suitably used to illuminate the direction of evacuation in the event of a fire. [Brief explanation of the drawings]
[0012] [Figure 1] 1 is a perspective view showing an example of an embodiment of a portable lamp of the present invention, and is a schematic view of the entire lamp. [Figure 2] FIG. [Figure 3] FIG. DETAILED DESCRIPTION OF THE INVENTION
[0013] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a portable lamp according to the present invention will now be described with reference to the drawings, taking as an example a case in which the fan is an axial flow fan.
[0014] Here, the terms "upper", "lower" and other terms indicating position and direction used in explaining this invention are used in accordance with the position and direction when the light-emitting part of the portable lamp is facing horizontally (as shown in Figures 1 to 3).
[0015] [Basic configuration] The portable lamp 1 has a light-emitting unit 2 on the front that uses an LED or the like as a light source, and a lamp body 3 that has a battery power source (not shown) inside, and is a portable lighting fixture that illuminates in the direction A1 of the light emitted by the light-emitting unit 2 (see Figures 1 to 3).
[0016] The lamp body 3 further includes a gripping portion 4 that the user holds when using the portable lamp 1, and an operating portion 5 for turning on / off the light-emitting portion 2 and the fan 6 described below (see Figure 1).
[0017] [fan] The portable lamp 1 is provided with a fan 6 that is provided on the lamp body 3 so as to protrude outward and that is capable of blowing air in the light irradiation direction A1 (see FIGS. 1 to 3).
[0018] [Improved visibility] The portable lamp 1 is equipped with a fan 6, which allows it to blow air in the light irradiation direction A1. Therefore, when used to illuminate the evacuation direction in the event of a fire or power outage, even if there is smoke, the fan 6 blows air forward to remove the smoke, while the light emitted by the light-emitting unit 2 illuminates the evacuation direction. In other words, even if there is smoke, visibility in the evacuation direction can be improved.
[0019] [Convection formation] Furthermore, although not shown in the drawings, the portable lamp 1 can create a convection current of smoke in the space in which it is used, including a flow of smoke along the light irradiation direction A1. That is, it can create a convection current of smoke, including a flow of smoke along the evacuation direction. This allows the user to proceed in the evacuation direction while clearing the smoke and improving visibility.
[0020] [Specific examples of fans] ·Air volume The fan 6 can be configured to have a blowing capacity that can blow air at a volume that can move smoke present in the light irradiation direction A1 forward by at least about 1 meter. If the smoke can be moved forward by about 1 meter, it will be possible to proceed in the evacuation direction while illuminating the front and ensuring visibility.
[0021] ·kinds The fan 6 is preferably an axial fan (see Figures 1 to 3). Although other types of fans, such as blower types, may be used, an axial fan reduces resistance to the airflow and makes it easier to obtain a large air volume with low power consumption.
[0022] ·Placement As mentioned above, it is preferable to position the fan 6 so that it protrudes outside the lamp body 3. This also reduces resistance to the airflow, making it easier to obtain a high air volume with low power consumption.
[0023] Furthermore, it is preferable to position the fan 6 in a position where it does not interfere with the grip part 4. It is also preferable to position the fan 6 in a position where the recoil of the air blown by the fan 6 can be easily suppressed. Specifically, for example, as in the illustrated example, when the grip part 4 is provided in the upper part of the lamp body 3, it is preferable to position the fan 6 in the lower part of the lamp body 3. Furthermore, as in the illustrated example, when the grip part of the grip part 4 is provided in the rear part of the lamp body 3, it is preferable to position the fan 6 in the front part of the lamp body 3 in relation to the moment.
[0024] Variable airflow direction and automatic swing function The fan 6 can be rotatable about a vertical axis and can change the airflow direction horizontally (see FIG. 2). In this case, the airflow direction can be changed automatically. By doing so, for example, the fan can change the airflow direction at a certain angle (e.g., 45 degrees) to the left or right, and can blow air not only in the light irradiation direction A1 but also to the left and right of the light irradiation direction A1, thereby expanding the range of improved visibility by removing smoke horizontally.
[0025] Folding and unfolding function The fan 6 can be mounted on the lamp body 3 so that it can rotate approximately 180 degrees around a horizontal axis and rise and fall (see Figures 1 and 3). Alternatively, the fan 6 can be mounted on the lamp body 3 so that its angle can be changed in approximately 45-degree increments around the horizontal axis. In this way, the fan 6 can be made foldable and unfoldable.
[0026] ·filter Although not shown, a smoke removal filter may be provided on the intake side of the fan 6. This allows smoke to be removed while also eliminating smoke in front of the fan.
[0027] [Operation mode selection function] The portable light 1 can be configured to have a selectable operating mode, and the selectable operating modes can include a first operating mode prioritizing smoke removal, in which the fan 6 has a high airflow rate while the light-emitting unit 2 operates at a low luminous intensity, and a second operating mode prioritizing illumination, in which the fan 6 has a low airflow rate while the light-emitting unit 2 operates at a high luminous intensity.
[0028] By providing such selectable operating modes, it is possible to select a first operating mode that prioritizes smoke removal in situations where there is a lot of smoke, and a second operating mode that prioritizes illumination in situations where there is little smoke, depending on the amount of smoke in the space of use.By making such selections, it is possible to reduce power consumption from the finite battery power source.
[0029] The operational modes may further include a third operational mode in which the fan 6 operates at a high airflow rate and the light-emitting unit 2 operates at a high luminance. In this way, for example, when evacuating, even if the distance exceeds about one meter and a greater forward visibility is required, the third operational mode can be selected to cope with the situation. However, because the third operational mode consumes a large amount of battery power, it is preferable to impose certain limitations on operation, such as limiting the operating time.
[0030] [Operation mode guide function] Although not shown in the figures, for example, the lamp body 3 may be provided with a selection operation unit for the above-mentioned operation modes, and the selection operation unit may be provided with a guide display unit that guides the user to select a first operation mode that prioritizes smoke removal when there is a lot of smoke, and to select a second operation mode that prioritizes illumination when there is little smoke.
[0031] [Charging terminal] The portable lamp 1 may be provided with a charging terminal section 7 in the lamp body 3, and the charging terminal section 7 may be provided with a charging terminal 7a for charging the battery built into the lamp body 3 and a charging terminal 7b for supplying power from the built-in battery to other devices.
[0032] [Configuration change example] An example of an embodiment of the portable lamp of the present invention has been described above with reference to the drawings, but the present invention is not limited to the above embodiment, and modifications to the configuration are possible within the scope of the gist of the invention.
[0033] For example, instead of or in addition to the configuration of the operation mode selection function, the portable light 1 can be configured to be capable of adjusting the airflow rate of the fan 6 and the luminous intensity of the light-emitting unit 2, so that when the airflow rate of the fan 6 is increased, the luminous intensity of the light-emitting unit 2 automatically decreases, and when the airflow rate of the fan 6 is decreased, the luminous intensity of the light-emitting unit 2 automatically increases.
