Description

  The present invention relates to a sensor light mainly used for crime prevention, which turns on or blinks (flashes) a light source by detecting an intruder.

  In general, a sensor light has a light source and illuminates the predetermined range by irradiating light from the light source toward a certain range, and a detection sensor unit that detects intrusion of an intruding object into a detection area And the light source is turned on or blinked by detection of an intruder by the detection sensor unit, and is mainly used for crime prevention. And what is comprised so that the irradiation direction by the said illumination part can be changed or adjusted in such a sensor light is also known (for example, refer patent document 1).

  Such a sensor light is installed at the entrance of a detached house in a residential area, a car port, etc., and is configured to turn on or blink a light source upon detection of an intruder by a detection sensor unit. When it is lit or flashing, it may illuminate both the left and right neighbors and the opposite residence, which may cause inconvenience, resulting in a so-called light pollution problem.

  On the other hand, when a light source with a small amount of light is used, it is possible to limit the illumination range within the house, but the required illuminance cannot be obtained, the illumination range becomes very dark, and the illumination effect cannot be obtained.

  Therefore, by controlling the irradiation direction of all or part of the light from the light source with the hood member, the illumination range by the sensor light is controlled, and the sensor light that can illuminate only the range required by the user (See Japanese Patent Application No. 2006-355567).

By the way, in order to prevent the so-called light pollution problem, it is necessary to avoid lighting to the right and left neighbors and the opposite houses, and to illuminate the lower part, so the light from the light source is irradiated downward by the regulation by the hood member. It is necessary to attach a hood member so that it may be.
JP-A-10-144134 (paragraphs 0009 to 0011 and FIG. 1)

  However, if the hood member is simply attached to the illuminating unit without any reference to be attached, the hood member cannot be attached to the illuminating unit at a predetermined position, and a part of the light from the light source is located on the left and right side or on the opposite side. There is a risk that it will be installed to illuminate.

  In addition, even if the lighting part to which the hood member is attached is supported so as to be able to swing, it is difficult to avoid illuminating the right and left neighbors and the opposite house by adjusting within the swingable angle range There is also.

  An object of this invention is to provide the sensor light which can attach a hood member to an illumination part accurately.

  The invention of claim 1 includes an illumination unit that has a light source and illuminates the certain range by irradiating the light of the light source toward a certain range, and the illumination unit is supported on the upper part so as to be able to swing, and the installation place And a detection sensor part that is provided at a lower part of the main body part or the lower part of the main body part and detects intrusion of the intruder into a predetermined detection area. A sensor light that turns on or blinks the light source upon detection of a hood member that is detachably attached to the illumination unit and regulates the irradiation direction of all or part of the light, and the illumination unit and the hood member Positioning means for positioning the hood member with respect to the illuminating unit, and the hood member is attached to the illuminating unit or the hood member is removed from the illuminating unit. Characterized in that it is used in a state. Here, depending on the shape of the hood member used, the entire irradiation direction of the light from the light source is restricted, or the irradiation direction of a part of the light is restricted.

  In this way, since the positioning means for positioning the hood member with respect to the illumination unit is provided between the illumination unit and the hood member, a range that can be swung by simply attaching the hood member to the illumination unit. By adjusting the direction of the illumination unit inside, it is possible to restrict the illumination to the right and left neighbors and the opposite residence, and attach it to a predetermined position where the lower part can be illuminated. Therefore, it is possible to attach the hood member to the illuminating unit based on the positioning means with high accuracy, and to avoid light damage to the neighboring neighborhood using the hood member.

  According to a second aspect of the present invention, the illumination unit includes an illumination main body that houses the light source, and a protective cap that protects the illumination main body by having a translucent part that transmits light from the light source. The protective cap part is detachably attached to the illumination main body part, and the hood member is sandwiched between the illumination main body part and the protective cap part, and is attached to the illumination part, and A hood main body connected to the base and extending from the illuminating part, and the positioning means includes an engaging part formed on at least one of the illuminating main body part or the protective cap part of the illuminating part; It can be comprised with the to-be-engaged part formed in the base part of the said hood member, and engaging with the said engaging part so that engagement / disengagement is possible. Here, the engagement relationship between the engaging portion and the engaged portion may be at least that restricts the circumferential position of the illumination main body portion or the protective cap portion of the illumination portion and the hood member.

  If it does in this way, the engaging part formed in at least one of the illumination main-body part of a lighting part or a protection cap part and the to-be-engaged part formed in the base of the said hood member will be engaged so that engagement / disengagement is possible. Thus, the hood main body part can regulate the irradiation direction of the light from the light source, and can be attached so as to avoid illumination to the right and left neighbors and the opposite house. And if it is such an engaging part and an engaged part, there is no possibility of affecting the attachment method to the installation place of the said main-body part.

  According to a third aspect of the present invention, there is provided a dummy ring that is used when the hood member is used in a state where it is detached from the illumination unit, and the dummy ring has a shape corresponding to a base part of the hood member; can do.

  In this way, it is not necessary to consider the lighting on the right and left sides or the opposite house, and when the hood member is removed, the light from the light source is directed toward the certain range as before. Can be illuminated to illuminate the certain range. In this case, since the dummy ring is disposed in the gap that sandwiches the base portion of the hood member, such a gap does not become a space. Therefore, a flammable material such as fallen leaves is sandwiched in the gap (space), and the problem that the lighting glass or the like becomes high temperature (about 200 ° C.) and burns is avoided.

  Further, the dummy ring has a shape corresponding to the base portion of the hood member, that is, the dummy ring has an engaged portion corresponding to the engaged portion of the base portion of the hood member. The dummy ring is also sandwiched in the same manner as the base portion of the hood member is sandwiched between the illumination main body portion and the protective cap portion, and the dummy ring can be attached without difficulty.

  In the present invention, as described above, the positioning means for positioning the hood member with respect to the illumination unit is provided between the illumination unit and the hood member. By adjusting the direction of the illumination unit within the swingable range, it is possible to avoid illumination of the right and left neighbors and the opposite residence, and to attach to a predetermined position where the lower part can be illuminated.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  1 is a perspective view showing an embodiment of a sensor light according to the present invention, FIGS. 2 (a) and 2 (b) are side and bottom views, and FIGS. 3 (a), 3 (b) and 3 (c) are hoods, respectively. It is the side view of the state which removed the member, the front view, and a top view.

  As shown in FIGS. 1 and 2 (a) and 2 (b), the sensor light 1 has a basic structure similar to that of the conventional one, and a main body 2 that is mounted and fixed at an installation location, and an upper portion of the main body 2. The lighting unit 3 is attached to be swingable in the left-right direction and the up-down direction, and the detection sensor unit 4 is attached to the lower end of the main body 2 so as to be rotatable in the left-right direction and the up-down direction. It is what is used.

  Next, the hood member 11 that is detachably attached to the illumination unit 3 and is a feature of the present invention, and the relationship between the hood member 11 and the illumination unit 3 will be described. Since the main body 2 and the detection sensor 4 have the same structure as that of the prior art, detailed description thereof is omitted.

  The illuminating unit 3 of the sensor light 1 is mounted on the front side of the lighting main body 3A and houses the lighting main body 3A (see FIG. 5) that houses the lamp 12 and the reflecting plate 13 as a light source, and protects the lamp 12 and the reflecting plate 13. A protective cap 3B. The illuminating unit 3 has a swingable angle range of 60 ° in the left direction and right direction, 120 ° in the horizontal direction, 10 ° in the upward direction, 50 ° in the downward direction, and 60 ° in the vertical direction. The lamp 12 is turned on or blinked when the detection sensor unit 4 detects the intrusion of the intruder.

  Moreover, the hood member 11 (hood part) which regulates the irradiation direction of a part of the light of the lamp 12 is detachably attached to the illumination part 3. Therefore, according to the place where the sensor light 1 is installed, the hood member 11 is used with being attached to the illumination unit 3 (see FIGS. 2A and 2B), or the hood member 11 is removed from the illumination unit 3. It can be used by selecting whether to use in the state (see FIGS. 3A to 3C).

  On the other hand, as shown in FIGS. 4A to 4D, the hood member 11 has a hood base portion 11A whose upper portion is formed in a substantially semi-cylindrical shape and a semicircular cross section connected to the front side of the hood base portion 11A. The hood member 11 is attached to the illuminating unit 3 by having the arc-shaped hood main unit 11B and the base 11A is sandwiched between the illuminating main unit 3A and the protective cap unit 3B. The inner surface of the hood main body portion 11B may be left as it is without being subjected to surface treatment, or may be subjected to surface treatment so as to increase the reflectance for reflecting light from the lamp.

  Further, the upper edge 11a of the upper portion of the hood member 11 is inclined forward and downward by an angle θ1, and the front edge 11b of the upper portion and the front edge 3a (the hood member 11) of the illumination unit 3 are seen in a side view. The hood shading angle θ2 formed by the base portion 11A) is in the range of 46 ° to 70 °. Therefore, the hood member 11 can be in a state in which the front edge 11b of the upper portion of the hood member 11 extends in a substantially horizontal direction in a side view at any angle in the angle range in which the illumination unit 3 can swing. Therefore, in this state, as will be described later, it is possible to prevent the light from the illumination unit from entering the third party's eyes almost at the third party's eyes passing outside the detection area. The user can finely adjust the illumination range with reference to. The rear edge 11c of the upper portion of the hood member 11 is inclined at an angle θ3 smaller than the hood light shielding angle θ2 in order to connect the front edge 11b to the base portion 11A.

  Also, the base 11A of the hood member 11 is formed with an engaging recess 11Aa, while the protective cap 3B can be engaged with and disengaged from the engaging recess 11Aa as shown in FIGS. 10 (a) and 10 (b). An engaging projection 3Ba to be engaged is formed. The engaging convex portion 3Ba (engaging portion) and the engaging concave portion 11Aa (engaged portion) constitute positioning means for positioning the hood member 11 with respect to the illumination portion 3.

  Therefore, when the hood member 11 is attached, the hood member 11 is attached to the illumination unit 3 by the engagement relationship between the engagement recess 11Aa and the engagement protrusion 3Ba, so that the hood member 11 transmits light in a predetermined irradiation direction. Precisely at the upper position (predetermined position) of the illuminating unit 3 so as to be able to illuminate the lower part so as to regulate the irradiation, that is, avoiding (or restricting) illumination to the right and left neighbors and the opposite house Will be attached. Here, since the base portion 11A of the hood member 11 is sandwiched between the illumination main body portion 3A and the protective cap portion 3B, the engagement relationship between the engagement concave portion 11Aa and the engagement convex portion 3Ba is related to the illumination portion 3. On the other hand, the hood main body 11B may be anything that does not rotate in the circumferential direction, and the shape thereof is not particularly limited.

  As the lamp (light source) of the illuminating unit 3, a halogen lamp is usually used, and the heat of the lamp raises the temperature of the hood member 11 to about 100 ° C. to 220 ° C. Therefore, a heat resistant material that can withstand this temperature is used. It is desirable to use it as a material for the hood member 11. Moreover, since the sensor light 1 is installed outdoors, such as a front door of a detached house in a residential area, a carport, etc., it is also desirable that the sensor light 1 be a material having good weather resistance.

  When the hood member 11 is attached, as shown in FIG. 5, the light transmitting from the waterproof packing 14, the light from the lamp 12, or the light reflected by the reflecting plate 13 is transmitted through the distal end tubular portion of the illumination main body 3 </ b> A. For example, the heat resistant glass 15, the base 11 </ b> A of the hood member 11, and the protective cap 3 </ b> B are attached in this order. The hood member 11 is attached and fixed to the illumination unit 3 by sandwiching the base 11A of the hood member 11 between the illumination main body 3A and the protective cap unit 3B.

  The protective cap part 3B is attached to the tip cylindrical part of the illumination main body part 3A by fitting or screwing. The protective cap portion 3B also has a function of protecting the illumination main body portion 3A.

  If the hood member 11 is provided in the illumination unit 3 as described above, when the sensor light 1 is viewed with the line of sight A when installed with the mounting height H as shown in FIG. 3 is inclined downward, and the lamp 12 and the reflector 13 are not completely visible due to the effect of restricting the irradiation direction by the hood member 11, which is advantageous in preventing light pollution. Note that although the line of sight A is not visible when it is the same height as the front edge 11b, the light from the lamp 12 is visible when it is below the broken line A 'below the line of sight A by an angle α.

  Therefore, if such a hood member 11 is not used for the illumination unit 3, as shown in FIG. 7B, the illumination spreads to both the left and right neighbors and the opposite residence, and light damage to the left and right neighbors and the opposite residence. If the hood member 11 is used and the swing angle of the illumination part 3 is adjusted, the hood member 11 (hood main body part 11B) is attached to the illumination part 3 as shown in FIG. On the provided side, the irradiation direction of the light from the lamp 12 is restricted, and the illumination range by the sensor light 1 is limited. Therefore, the illumination range is limited by the hood member 11, and the light damage that the light of the lamp 12 is irradiated to the right and left side neighbors or the opposite residence is avoided. The light shielding distance can be adjusted by appropriately changing and combining the hood light shielding angle θ2 of the hood member 11 and the swing angle β of the illuminating unit 3.

  Further, when it is necessary to consider the light damage to the neighboring neighborhood, as shown in FIG. 8, when the hood member 11 is used with the hood member 11 removed, the waterproof packing is attached to the tip cylindrical portion of the illumination main body 3A. 14, the heat-resistant glass 15, the dummy ring 21, and the protective cap part 3B are attached in this order. The dummy ring 21 fills a gap formed between the illumination main body 3A and the protective cap 3B when the hood member 11 is removed. As shown in FIGS. 9 (a) and 9 (b), An engagement recess 11 </ b> Aa that has a shape corresponding to the base 11 </ b> A of the hood member 11 and is detachably engaged with the engagement protrusion 3 </ b> Ba of the protective cap 3 </ b> B is formed. Therefore, the dummy ring 21 is attached so as not to rotate in the circumferential direction in a predetermined positional relationship due to the engagement relationship between the engagement concave portion 21a and the engagement convex portion 3Ba.

  In this manner, the dummy ring 21 is attached and fixed by being sandwiched between the illumination main body portion 3A and the protective cap portion 3B, similarly to the base portion 11A of the hood member 11.

  In addition to the embodiment described above, the present invention can be implemented with the following modifications.
