Description

  The present invention relates to an illumination device having a negative ion generation function and a circulator function suitable for use in homes and various facilities.

  Conventionally, when negative ions are released into the air, electrons are given to the positively charged pollutants floating in the air, changing them into negative charges, and these negatively charged pollutants and the positive charges remain floating. This process is repeated and the pollutant swells up to thousands of times its weight, and the swelled pollutant can no longer float in the air and falls to the floor Therefore, it is known that the contaminants in the air can be removed. It is also known that a small amount (low concentration) of ozone has a deodorizing and sterilizing action. Therefore, in the past, devices that generate negative ions and ozone were attached to various devices (for example, air purifiers and other household appliances), and negative ions were released into rooms that were biased to positive ions, so that the ion balance was in an appropriate state. Maintains and improves human health, and at the same time deodorizing and sanitizing indoors.

  By the way, in the case of an air purifier, since it is usually installed in the lower part of the room, it is difficult to supply negative ions or ozone (hereinafter referred to as “negative ions”) to the air in the whole room including the vicinity of the ceiling. It was. Therefore, in order to solve such problems and ensure a sufficient supply of negative ions, a negative ion generator is attached to the ceiling, and negative ions flow out from the negative ion generator directly below. good. If comprised in this way, it will become possible to supply a sufficient amount of negative ions to the air in the entire room including the vicinity of the ceiling.

  Conventionally, as a circulator for circulating indoor air, there is one in which a fan is installed on the ceiling.

However, when a negative ion generator or a circulator is installed on the ceiling, there are the following problems.
(1) A lighting fixture is usually installed on the ceiling, but a negative ion generator or circulator will be installed at a different location, which requires large-scale ceiling processing and wiring work. End up. In addition, the cost is high, and there is a risk that the appearance of the apparatus may deteriorate due to the installation of many instruments on the ceiling.

(2) Even if a negative ion generator or circulator can be installed at the location where a conventional lighting fixture is installed, the outlet for the lighting fixture is different from the outlet for the negative ion generator or circulator. Construction will be required.

  The present invention has been made in view of the above points, and its purpose is that it does not require large-scale installation work and the like, has good appearance, can be reduced in cost, can exhibit an effective negative ion generation function and a circulator function, and at the same time. An object of the present invention is to provide an illumination device capable of obtaining a suitable illumination effect.

The invention according to claim 1 of the present invention is a case having an outer shape that is inserted into a downlight mounting recess provided on a ceiling, and an illumination light emission that is attached to the case and emits light downward from the case. Means, negative ion generating means for generating negative ions housed in the case, and negative ions generated by the negative ion generating means by taking air outside the outer peripheral surface of the case housed in the case into the case An illumination device with a circulator and a negative ion generating means , and a fan for causing the ions to flow out directly below the case together with the ions , wherein the illumination light emitting means is on the outer peripheral side surface of the case and fired Installed so that light mainly travels downward in parallel with the outer peripheral side surface of the case, while at the bottom of the case, A ridge portion is attached to the tip portion of the luminaire that protrudes diagonally downward from the outer periphery of the rim in the radial direction, and the tip portion of the ridge portion extends horizontally. It is installed at a position where a predetermined gap is formed with the ceiling surface around the mounting recess to form an air suction flow path from the horizontal direction. Is a reflective surface that reflects light emitted downward from the light emitting means for illuminating, so that part of the light hitting the reflective surface is transmitted and at the same time the remaining part of the light is reflected. The illumination device includes a circulator and negative ion generating means, which illuminates the ceiling surface and indirectly illuminates the room through the air suction flow path .

According to the first aspect of the present invention, the negative ion generating means, the indoor air circulation fan, and the illumination light emitting means can be inserted into the downlight mounting recess provided on the ceiling. Large ceiling work and wiring work for attaching the ion generating means and the circulator are not required, and the cost can be reduced. At the same time, it is possible to illuminate the room from the inside of the downlight mounting recess. In particular, since the fan for indoor air circulation is installed together with the negative ion generation means, the negative ions generated by the negative ion generation means can be put out on the air flow generated by the fan and flow out downward of the case. It is possible to sufficiently supply and circulate the generated negative ions to the air in the entire room. In addition, since the negative ion generating means and the circulator need not be installed on the ceiling surface other than the downlight mounting recess, the appearance of the ceiling is improved.

According to the invention described in claim 1, light emitted from the illuminating light emitting means is transmitted and refraction及beauty reflections are against the upper surface of the umbrella portion. In other words, the interior of the room can be effectively illuminated by the light exerting the light scattering action.

According to the first aspect of the present invention, an air supply path including a predetermined gap is formed between the cover portion and the ceiling surface. Therefore, the air flowing out downward of the illumination device is caused by the cover portion. Since it is directed to the direction perpendicular to the ceiling surface (directly below) in a state of being partitioned from the supply path, the air blown out from the illumination device is not immediately sucked into the illumination device but circulated widely in the room. Later, the light returns to the illumination device, and air can be effectively circulated in the room.

  Returning to FIG. 1, the fan 50 is installed so as to suck air from the suction port 51 on the side surface and to discharge air from the air discharge port 53 directed downward. The change-over switch 60 switches the illumination device 1 to four states, and is configured so that the state is changed each time the operation string 61 pulled out from the change-over switch 60 is pulled. That is, in the first stage where the operating cord 61 is pulled, the illumination means 120, the negative ion generation means 30 and the fan 50 are on, and in the second stage, only the illumination means 120 and the negative ion generation means 30 are on. In the third stage, only the illumination means 120 and the fan 50 are on. In the fourth stage, all of the illumination means 120, the negative ion generation means 30, and the fan 50 are off.

  The DC conversion board 70 is a board for converting the AC power source taken from the base 100 into a DC 12V DC power source, and the high voltage generating board 80 converts the DC power source converted by the DC conversion board 70 into a high voltage. This is a substrate supplied to the negative ion generating means 30. The light-emitting display member 90 is configured by installing a pair of light-emitting elements 91 and 93 on the lower surface of the substrate, and the pair of light-emitting elements 91 and 93 are positioned to face the small openings 25 and 27 for operating state display, respectively. is doing. One light emitting element 91 is lit when the negative ion generating means 30 is operated, and the other light emitting element 93 is lit when the fan 50 is operated. The base 100 is a base having a shape and a structure that is screwed into a socket 230 provided on the upper and bottom surfaces of the downlight mounting recess 200 shown in FIG. 4 (that is, the same base as the light bulb).

  The illuminating means 120 includes a light emitting means attachment 121 attached to the outer periphery of the case 10 so as to surround the case 10 in a ring shape, and a plurality of illumination light emitting means 130 attached to the light emitting means attachment 121. Yes. The light emitting means fixture 121 is formed of a molding resin (or other material such as metal) in a ring shape, and a concave storage portion 123 is provided on the inner peripheral side thereof, and from the inner peripheral side end portion on the upper portion thereof. A mounting portion 125 protruding in a ring shape is provided. A plurality of illumination light emitting means 130 (four in this embodiment, but may be a predetermined number of one or two) may be accommodated and installed in the storage unit 123 at equal intervals. Further, the light emitting portion 131 on the front end side that emits light of each illumination light emitting means 130 protrudes from the lower surface of the light emitting means fixture 121. Therefore, the light emitted from the light emitting unit 131 of the illumination light emitting means 130 travels downward, mainly directly below, that is, parallel to the outer peripheral side surface of the case 10. The illumination light emitting means 130 is supplied with power from the DC conversion substrate 70 side inside the case 10. The illumination light emitting means 130 is made of a light emitting diode, and the amount of light thereof may be as much as that of a night light, or may be that of light that can be used as a normal illumination lamp.

  The bristle part 110 protrudes in the form of a bristle from the outer periphery of the lower part of the case 10 toward the outer side in the radial direction, and its outer diameter is formed to be larger than the inner diameter of the downlight mounting recess 200 by a predetermined dimension. The cap part 110 is an integrally molded product of a translucent molding resin, and is attached to the lower outer periphery of the case 10 so as to surround the cylindrical ring-shaped mounting part 111, and radially outward from the lower end side of the mounting part 111. A conical surface-shaped projecting portion 113 projecting obliquely downward toward the surface, and a ring-shaped tip portion 115 projecting horizontally from the outer periphery of the projecting portion 113 toward the radially outer side are provided. . Further, the material of the cap portion 110 will be described. It is translucent and milky white, and is made of a molded resin material that transmits part of the light while irregularly reflecting and refracting it, and at the same time reflects a part of the light on its surface. Yes.

  As shown in FIG. 4, the illumination device 1 configured as described above is mounted in the downlight mounting recess 200 inside the downlight case 210 fixed to the ceiling 250. Here, the downlight case 210 is formed by forming a metal plate into a bottomed cylindrical shape, and a wiring terminal 220 is attached to the center of the upper end surface (the center of the upper bottom as viewed from the downlight mounting recess 200). ing. The wiring terminal 220 is connected to a wiring (not shown) installed behind the ceiling. A socket 230 is attached inside the downlight mounting recess 200 below the wiring terminal 220. The downlight case 210 is a normal downlight case that houses a light bulb or a bulb-type fluorescent lamp and attaches the base to the socket 230. The downlight case 210 is inserted into an opening 251 provided on the ceiling 250 and is fixed to the ceiling 250 by a fixture 253 provided on the outer peripheral end of the opening side. The illumination device 1 can be mounted in the downlight mounting recess 200 only by inserting the illumination device 1 into the downlight mounting recess 200 and screwing the cap 100 into the socket 230. That is, in the present invention, since the base 100 is attached to the illumination device 1 and the case 10 is configured to be inserted into the downlight mounting recess 200, the illumination device 1 is the same as the attachment of the normal light bulb to the downlight. It can be easily mounted in the downlight mounting recess 200 by this method. In the illumination device 1 mounted in the downlight mounting recess 200 as described above, the cover portion 110 projects from the lower portion of the ceiling surface (the lower surface of the ceiling 250) 255 around the downlight mounting recess 200. At this time, a predetermined gap S is formed between the ceiling surface 255 and the bulk portion 110. In other words, according to the present invention, when the illumination device 1 is mounted in the downlight mounting recess 200, a predetermined gap S is provided between the illumination device 1 and the ceiling surface 255 around the downlight mounting recess 200. A casket portion 110 is provided.

  For example, assuming that the illuminating device 1 is turned off, when the operation string 61 is pulled once, the illuminating light emitting means 130, the negative ion generating means 30, and the fan 50 are turned on simultaneously. At this time, both the light emitting elements 91 and 93 are simultaneously turned on. Lights up. When the illumination light emitting means 130 is turned on and lit, the light emitted from the light emitting portion 131 of the illumination light emitting means 130 travels downward, mainly directly below, that is, parallel to the outer peripheral side surface of the case 10, It hits the upper surface (particularly, the overhanging portion 113 in this embodiment) of the bevel portion 110. A part of the light radiated to the bulk 110 transmits through the bulk 110 while being refracted and diffusely reflected, and illuminates the room as soft light having a predetermined spread from the lower surface side. On the other hand, the remaining part of the light is reflected by the cover 110 and applied to the ceiling surface 255 to indirectly illuminate the room. The illumination light emitting means 130 may be used as a night light or a normal illumination light depending on the light quantity of the light emitting unit 131. Moreover, in this embodiment, although the cap part 110 was comprised with the translucent molding resin, you may comprise it with a completely transparent molding resin as needed, for example, the upper surface (or lower surface) is made into a total reflection surface. The light emitted from the light emitting unit 131 may be totally reflected by the upper surface (or the lower surface) of the cover unit 110, and all of the light may be irradiated to the ceiling surface 255 for indirect illumination. In order to obtain a total reflection surface, for example, the bulk 110 may be made of a metal plate, or a total reflection surface (for example, by plating or vapor deposition of a metal film) may be formed on the upper surface or the lower surface of a synthetic resin plate or a glass plate. good. If necessary, only a part of the umbrella portion 110 may be translucent, or only a part may be a total reflection surface. Further, the upper surface or the lower surface of the cap portion 110 may be formed into a number of irregularities or treated with a satin finish to scatter light on the surface, or the material of the cap portion 110 may be made of a phosphorescent material. You may make it radiate | emit softer light from the bulk part 110 by apply | coating a phosphorescent paint to the surface.

  On the other hand, when the negative ion generating means 30 is turned on simultaneously with the light emission of the illumination light emitting means 130, a DC high voltage is applied between the pipe electrode 31 and the needle electrode 35 to generate corona discharge, and a large amount of negative ions and A small amount of ozone is generated, and a negative ion and a wind containing ozone (fine wind) are generated by this discharge energy, so that the air introduced from the negative ion air introduction opening 19 gradually becomes negative ions as shown by the dotted arrows. It discharges from the discharge port 23 (refer FIG. 2). At the same time, the air introduced into the fan 50 from the fan air introduction opening 17 by the drive of the fan 50 is ejected from the fan air ejection port 21 (see FIG. 2). The direction to be ejected is a direction from the ceiling 250 toward the bottom (vertical). Therefore, the air containing negative ions and ozone merges with the air blown from the fan 50 and is accelerated, descends from the ceiling 250 toward the floor, then circulates in the room and returns to the vicinity of the ceiling 250 again. It is again introduced into the illumination device 1. That is, the fan 50 serves as a circulator (air circulation device). As a result, negative ions and a small amount of ozone can be efficiently and evenly supplied to all the indoor spaces, and the air in the entire room can be cleaned, sterilized, and deodorized, thereby creating a healthy and comfortable environment.

  By the way, as shown by an arrow in FIG. 4, the air introduced into the illumination device 1 is from the side surface of the case 10, while the air ejected from the illumination device 1 is from the lower surface of the case 10. Therefore, all of the air introduced into the illumination device 1 is introduced through the gap S formed between the ceiling surface 255 and the bulkhead portion 110 (that is, the gap S forms an air supply path to be supplied into the case 10. ), A suction channel from a horizontal direction is mainly formed on the ceiling surface 255. On the other hand, the air ejected from the illumination device 1 is directed in a direction perpendicular to the ceiling surface 255. Therefore, the air containing negative ions and ozone ejected from the illumination device 1 is not immediately sucked into the illumination device 1 but returns to the illumination device 1 after widely circulating in the room.

  Next, when the operation cord 61 is pulled again, the fan 50 stops and the light emitting element 93 is turned off, the negative ion generating means 30 and the light emitting means 130 for illumination are kept on, and only the light emitting element 91 is turned on at the same time. Continue. When the negative ion generating means 30 is kept on, a large amount of negative ions and a small amount of ozone are generated and released from the negative ion discharge port 23 in a breeze state as described above. In this case, the wind heading directly from the ceiling 250 is a slight wind and cannot be circulated at a high speed as in the case where the fan 50 is used, but gradually circulates. When the fan 50 is driven, noise is inevitably generated, so it is better to stop it when it is quiet, such as after the lights are turned off at night. At the same time, the air turbulence in the room is considerably reduced. It is possible to purify the air in the entire room and to disinfect and deodorize it.

  Next, when the operation cord 61 is pulled again, the fan 50 is activated and the negative ion generating means 30 is stopped, the illumination light emitting means 130 is kept on, and at the same time, the light emitting element 91 is turned off and the light emitting element is turned on. 93 lights up. In this case, since the negative ion generating means 30 is turned off, the air discharged from the illumination device 1 by the fan 50 is only normal air. Therefore, the illumination device 1 performs the same action as a normal circulator, and the room air Circulate efficiently. Then, when the operation cord 61 is pulled again, the fan 50 and the light emitting means for illumination 130 are stopped, the light emitting element 93 is also turned off, and a complete stop state (off state) is entered.

  FIG. 5 is a schematic cross-sectional side view showing a state in which an illuminating device 1-2 with negative ion generating means and a circulator according to another embodiment of the present invention is mounted in a downlight case 210. In the illumination device 1-2 shown in the figure, the same reference numerals are given to the same or corresponding parts as those of the illumination device 1 and the downlight case 210 according to the embodiment shown in FIGS. Items other than those described below are the same as those in the embodiment shown in FIGS. The illumination device 1-2 is different from the illumination device 1 in that the DC conversion substrate 70 installed in the case 10 in the illumination device 1 is placed on the upper end surface of the downlight case 210 (downlight mounting recess 200). When viewed from the side, it is installed on the back side of the bottom surface, and a wiring (not shown) installed on the back of the ceiling is connected to the DC conversion board 70, and then the power converted into DC by the DC conversion board 70 is used for wiring. A power outage backup board 140 provided with a power outage backup circuit is newly installed at the point where the power is supplied to the socket 230 of the terminal 220 and the position where the DC conversion board 70 inside the case 10 is installed in the illumination device 1. This is the point. In this embodiment, the illumination light emitting means 130 is used as a night light.

  FIG. 6 is an electric circuit diagram of the illumination device 1-2. As shown in the figure, the electrical circuit of the illumination device 1-2 is configured such that an AC power source (commercial power source, AC 100V) is converted into a direct current (DC 12V) by the DC conversion board 70, and then the direct current power source is connected to the fan 50. The light emitting elements 91 and 93, the high voltage generating substrate 80, and the power failure backup substrate 140 are configured to be supplied in parallel. A changeover switch 60 is attached in the parallel circuit, and the supply of electric power to each of the electrical components is turned on and off by switching the changeover switch 60. A circuit for detecting whether or not the supply of DC power from the DC conversion board 70 is stopped (that is, whether or not a power failure has occurred) is connected to the power failure backup board 140 separately. In addition, a battery 141 and an illumination light emitting means 130 are connected to the circuit of the power failure backup board 140. The battery 141 stores power during normal operation of the illumination device 1-2, and when the power failure backup substrate 140 detects that the supply of power from the DC conversion substrate 70 is stopped, the light emission for illumination is performed until the time of the power failure. Regardless of whether power is supplied to the means 130, the power stored in the battery 141 is supplied to the illumination light emitting means 130. In this embodiment, the battery 141 is attached to the outer surface (upper surface) of the case 10. The battery 141 is a dry cell type, and can be easily attached and detached (replaced). The change-over switch 60 switches the illumination device 1-2 to three states. In the first stage in which the operation cord 61 is pulled, the illumination light emitting means 130, the negative ion generation means 30, and the fan 50 are turned on. In the second stage, only the illumination light emitting means 130 and the negative ion generating means 30 are on. In the third stage, the illumination light emitting means 130, the negative ion generating means 30 and the fan 50 are used. Both of these are in the off state, and when the operation string 61 is pulled next, the state of the first stage is entered again.

  For example, assuming that the illumination device 1-2 is turned off, when the operation string 61 is pulled once, the illumination light emitting means 130, the negative ion generating means 30, and the fan 50 are simultaneously turned on. , 93 are lit. The actions of the illumination light emitting means 130, the negative ion generating means 30, and the fan 50 are the same as those of the illumination device 1. In this embodiment, the illumination light emitting means 130 is used as a night light, but it may be used as a normal illumination lamp.

  Next, when the operation cord 61 is pulled again, the fan 50 stops and the light emitting element 93 is turned off, the negative ion generating means 30 and the light emitting means 130 for illumination are kept on, and only the light emitting element 91 is turned on at the same time. Continue. The operation at that time is the same as that of the illumination device 1.

  Next, when the operation cord 61 is pulled again, the negative ion generating means 30 and the light emitting light emitting means 130 are stopped, the light emitting element 91 is also turned off, and a complete stop state (off state) is established.

  On the other hand, when the AC power supply (commercial power supply) fails, the power failure backup board 140 detects the power failure, switches the power supplied from the power failure backup board 140 to the illumination light emitting means 130 to the battery 141, and the illumination light emission means 130. Illuminate. The power supply from the battery 141 to the illumination light emitting means 130 is performed both when the changeover position of the changeover switch 60 is in a state in which the illumination light emission means 130 is illuminated and in a state in which the illumination is stopped. . That is, when the AC power supply fails, the illumination light emitting means 130 always emits light. Therefore, the light emitting means 130 for illumination normally has a function as a night light (or illumination lamp), and also has a function as an illumination or guide lamp in the event of a power outage or disaster.
