Description

  The present invention relates to a fitting room lighting device installed in a fitting room (fitting room) that a person enters when trying on clothes.

  The fitting room lighting device installed in the fitting room used for trying on clothes effectively improves the willingness to purchase when customers select from candidate clothes, such as in a clothing store or department store. Therefore, there is a need for lighting that allows you to see the texture of clothing.

  More specifically, as shown in FIG. 11, the customer has the expectation that he wants to select clothes without mistakes, understands the characteristics of the clothes, and easily decides to purchase. For this reason, the following function is calculated | required by the illuminating device for fitting rooms. First, in order for customers to select their clothes without mistakes, the lighting from the fitting room lighting device should be bright from the customer's neck to the floor, not only the front of the clothes but also the sides, and the color appearance. There is a need to satisfy that it is favorable and faithful and that the lighting is not dazzling. In addition, in order to understand the characteristics of clothes, it is necessary to satisfy that shading (representation of irregularities) and reflected light of the light source are preferable. In addition, in order to make a purchase decision, it is necessary to satisfy that you can imagine the atmosphere when you are dressed in various situations.

  In addition, it is generally known that brightness (illuminance) is important, but in order to make the texture of clothing easy to understand, shading and appropriate reflection are important. Taking shading as an example, it is necessary to express the types and weaving methods of clothes well.

  As a conventional fitting room lighting device, Patent Literature 1 discloses a device that makes a fitting room light similar to sunlight. Such an apparatus of Patent Document 1 makes it possible to confirm the color of a material with a color close to sunlight. Patent Document 2 discloses a lighting fixture (illumination device) that creates daytime, nighttime, indoor and outdoor brightness by a combination of a fluorescent lamp and a light bulb. Further, Patent Document 3 discloses a lighting load that can change the color and brightness, an appliance driving unit that can change the light distribution characteristics of the lighting load, and a portable device for operating the lighting state of the lighting load. There is disclosed a lighting device that includes a multi-function unit and that can arbitrarily change the lighting atmosphere of a space.

  However, the illuminating devices of Patent Documents 1 and 2 lacked ingenuity for ensuring brightness. Further, Patent Documents 1 to 3 do not disclose specific means for creating the illumination state as described above.

As a solution to the above problem, Patent Document 4 discloses a lighting device that irradiates upwards a spotlight provided on a lower side toward clothes worn by a person. Although it is difficult to evaluate clothes worn by a person only from above, it is possible to improve the evaluation of clothes by irradiating from below as in the illumination device of Patent Document 4.
Utility Model Registration No. 3039273 (paragraph 0005 and FIGS. 1 and 2) Utility Model Registration No. 3085163 (paragraph 0008 and FIG. 2) JP-A-6-310284 (paragraphs 0015 to 0071 and FIG. 1) JP-A-10-227138 (paragraphs 0019 to 0067 and FIG. 1)

  However, since the conventional fitting room illumination devices in Patent Documents 1 to 4 irradiate only with a surface light source or a point light source, it is difficult to make the depth of the shadow, that is, the shadow of the clothes worn by a person a desirable state. There was a problem.

  The present invention has been made in view of the above points, and an object of the present invention is to provide an illumination device for a fitting room that can bring the fitting room into a preferable illumination state.

  The invention of claim 1 is a lighting device for a fitting room installed in a fitting room that a person enters when trying on clothes, and the luminance L1 of a non-shadow portion and a shadow portion in a predetermined portion of the clothing. And an irradiating means for irradiating the clothes with a depth of shadow S = (L1−L2) / L1 of 0.76 or more and 0.78 or less obtained from the luminance L2 of the image.

  The invention of claim 2 is characterized in that, in the invention of claim 1, the color temperature of the light from the irradiation means is 4200K or more and 5000K or less.

  According to a third aspect of the present invention, in the first or second aspect of the present invention, the irradiation means is provided on both sides of the mirror together with a mirror that reflects the clothes, and a pair of surface light sources that irradiate the clothes, A pair of point light sources which are provided on both sides and above the pair of surface light sources and which illuminate the clothes.

  According to the first aspect of the present invention, for example, in a store such as a clothing store or department store, when a customer selects from candidate clothes, the customer's willingness to purchase is effectively improved, or the fibers, types, and weaving methods of clothes. In order to express the texture of the clothing such as the surface condition well, the appearance of the shadow depth can be made favorable, so the store side can select high-value-added clothing from customers. Opportunities can be raised, customers can select clothes without hesitation, and shopping is not painful.

  According to the invention of claim 2, it is possible to make the appearance of the shadow depth more preferable.

  According to invention of Claim 3, it can install so that it may not interfere with fitting in a fitting room.

(Embodiment 1)
The configuration of the fitting room lighting device according to the first embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 1A, the fitting room lighting device 1 enters a room when a person (customer) 20 (see FIG. 1B) tries on a garment 2 (see FIG. 1B). It is installed in the fitting room 3 together with the mirror 4, and is provided on both sides of the mirror 4 in the vertical direction, and is provided with a pair of surface light sources 5 and 5 that irradiate the clothes 2, and both sides of the mirror 4 in the vertical direction. And a pair of point light sources 6 and 6 that are provided above the pair of surface light sources 5 and 5 and irradiate the clothes 2.

  As shown in FIG. 2B, the fitting room 3 is surrounded by four sides and has a size that allows the garment 2 to be tried on while a person 20 is standing. In the first embodiment, the width is 1.4 m × depth 1.4 m × height 2.5 m (see FIG. 1A).

  The mirror 4 reflects the clothes 2 worn by the person 20 and is provided in the center of the front of the fitting room 3 as shown in FIG. In particular, the length of the mirror 4 in the vertical direction is 1.2 meters or more so that the person 20 trying on can see the chest and neck of the clothes 2.

  Each of the pair of surface light sources 5 and 5 is, for example, a three-wavelength light-emitting fluorescent tube having a length of 1.2 m and a color temperature of 5000 K. Is provided symmetrically on both sides of the mirror 4 with the longitudinal direction being the vertical direction so that the height is 0.4 m from the floor of the fitting room 3. The distance between the pair of surface light sources 5 and 5 is 1.2 m, and each surface light source 5 is located at a distance of 0.6 m from the center of the mirror 4. As shown in FIG. 2A, the luminaire 50 includes a fixture body 51 having a width of 0.12 m and a reflector that reflects light from the surface light source 5 toward the clothing 2 (see FIG. 1B). 52 and a panel 53 such as a milky white panel or a prism panel.

  The solid angle of the irradiation range of each surface light source 5 is 0.26 sr (steradian) or more and 0.30 sr or less. Moreover, the center irradiation direction of the surface light source 5 is viewed from the upper side of the fitting room 3 from the axes a3 and a4 parallel to the side surface of the fitting room 3, as shown in FIG. It is tilted 34 degrees. The target luminous intensity of the mixed light from the pair of surface light sources 5 and 5 is 1800 ± 200 cd, and the vertical surface illuminance is 1500 lx or more and 2000 lx or less. The irradiation range of each surface light source 5 is as shown in FIG. 2B (FIG. 2B shows the case where the light intensity is 350 (cd / 1000 lm)).

  Here, the installation location of the surface light source 5 will be described. As the installation place of the surface light source 5, a ceiling (not shown), the upper side of the mirror 4, and both sides of the mirror 4 can be considered. Among these, when installed on the ceiling, it is difficult to obtain vertical surface illuminance, which is the illuminance in the vertical direction, from the mirror 4 of the person (fitting person) 20, so when installed above the mirror 4 and when installed on both sides of the mirror 4 Compare with. In FIG. 3, the vertical surface illumination intensity by the installation place of the surface light source 5 per the same supplied electric power is shown. According to FIG. 3, when the surface light source 5 is installed on both sides of the mirror 4 (● in FIG. 3) above the mirror 4 until the height of the fitting room 3 from the floor surface is at least 1.2 m. Greater vertical surface illuminance can be obtained when installed (▲ in FIG. 3).

  The pair of point light sources 6 and 6 in FIG. 1A is, for example, an incandescent bulb having a color temperature of 2800K (including a reflector or filter that has been subjected to multilayer film processing to remove infrared rays), etc. 3 is provided above the surface light source 5 at a height of 1.8 m from the floor surface.

  The solid angle of the irradiation range of each point light source 6 is 0.001 sr or more and 0.005 sr or less. Further, the central irradiation direction of the point light source 6 is inclined by 34 degrees from the axes a5 and a6 parallel to the side surface of the fitting room 3 to the center side of the fitting room 3 when viewed from the upper side of the fitting room 3 (see FIG. 1C). ), When viewed from the front of the fitting room 3, it is inclined by 60 degrees from the axes a1 and a2 parallel to the side surface of the fitting room 3 to the center lower side of the fitting room 3 (see FIG. 1A). The mixed light from the pair of point light sources 6 and 6 is 450 ± 50 cd, and the vertical surface illuminance is 450 lx to 500 lx. Note that the pair of point light sources 6 and 6 may be one that converts the color temperature to 4000K or more and 5000K or less by applying a multilayer film treatment to the reflector or the filter.

  As shown in FIG. 4, the color temperature of the mixed light can be adjusted by the luminous flux ratio in the light from these two types of light sources (surface light source 5 and point light source 6). For example, if the luminous flux ratio between the surface light source 5 having a color temperature of 5000K and the point light source 6 having a color temperature of 2800K is 3: 1 (75:25), the color temperature of the mixed light is about 4300K. Even when the luminous flux ratios of the two types of light sources are adjusted, the average color rendering index Ra is maintained at 80 or more.

  Subsequently, the shadow of the clothes 2 worn by the person 20 will be described. In the fitting room 3, it is necessary to express the type and weave of the clothes 2 well, and the illumination by the fitting room lighting device 1 plays a large role. In particular, the solid angles and irradiation directions of the surface light source 5 and the point light source 6 are affected. Here, “shadow depth” is used to represent the shadow of the clothes 2. The depth of the shadow quantitatively represents the state of the shadow, and is expressed as a contrast between the luminance (illuminance) lost due to the shadow and the luminance (illuminance) when there is no shadow. Specifically, as shown in FIG. 5, the luminance of a portion without a shadow in a predetermined portion of the garment 2 (in the first embodiment, a portion having a height of about 1.2 m from the floor surface of the fitting room 3) is expressed as L1. If the luminance of the shadow portion is L2, the shadow depth S of the object is obtained from the two luminances L1 and L2, and S = (L1−L2) / L1. The shadow depth S is a value that greatly depends on the solid angle of the irradiation range of the surface light source 5 and the point light source 6. Specifically, when the solid angle of the irradiation range of the surface light source 5 and the point light source 6 is increased, the shadow depth S is decreased. On the other hand, when the solid angle of the irradiation range of the surface light source 5 and the point light source 6 is reduced, the shadow depth S is increased.

  Considering only the determination of the shadow state, the surface light source 5 and the point light source 6 need only be installed on one side of the mirror 4 in FIG. Since it cannot be specified, in the first embodiment, one surface light source 5 and one point light source 6 are installed on both sides of the mirror 4.

  In the first embodiment, the appearance of the garment (white blouse) 2 was evaluated by changing the color temperature and the solid angle while keeping the irradiation directions of the surface light source 5 and the point light source 6 constant. First, the evaluation method will be described. The distance between clothes 2 and mirror 4 is 0.9 m. In this state, a position 1.2 m in height from the bottom surface of the fitting room 3 in the clothes 2 is set as an evaluation position. The shadow depth S at this evaluation position was determined. Among these, the shadow depth S when the solid angle of the surface light source 5 and the point light source 6 is minimum is 0.84, and the shadow depth when the solid angle of the surface light source 5 and the point light source 6 is maximum. S was 0.76. The shadow depth S in each illumination state is distributed between 0.76 and 0.84. It should be noted that the illuminance in all illumination states was set to 1100 lx or more and 1200 lx or less in order to appropriately grasp the color information.

  The evaluators are 14 men and women (average age 31 years, standard deviation 3.7). In addition, as an evaluation scale for the appearance of clothes 2, "brightness impression and clothes characteristic expression" and "warm cool feeling", etc., "preferable" and "not preferable" at both ends, "neither" A 7-level rating is used in the center.

  FIG. 6 shows a relationship between the shadow depth S and the overall evaluation of the preference of the appearance of the clothes 2. The combination of the surface light source 5 and the point light source 6 is shown in FIG. The surface light source 5 has a length of 1.2 m, a width of 0.12 m, and a solid angle of 0.48 sr. In FIG. 7, EX-N is a daylight fluorescent lamp (color temperature 5000K), and EX-L is a bulb-color fluorescent lamp (color temperature 2850K). The diameter of the point light source 6 is 0.1 m, and the solid angle is 0.005 sr. Further, the color temperature of the point light source 6 is adjusted to 2750K, 3400K, and 4600K by a combination of the light source itself, a reflector, and a filter. In the case of setting numbers 1 to 3 in FIG. 7, when only the point light source 6 is turned on, in the case of setting numbers 4 to 7 when the EX-N fluorescent lamp and the point light source 6 are turned on, the setting number 8 is EX-N fluorescence. When only the lamp is turned on, setting numbers 9 to 12 are when the EX-L fluorescent lamp and the point light source 6 are turned on, and setting number 13 is when only the EX-L fluorescent lamp is turned on.

  From FIG. 6, when the depth S of the shadow obtained by the surface light source 5 and the point light source 6 is 0.76 (▲ in FIG. 6) or more and 0.78 (● in FIG. 6) or less, the appearance of the clothes 2 is seen. It becomes preferable. More preferably, the shadow depth S is 0.78. On the other hand, when the shadow depth S is 0.80 (■ in FIG. 6) or 0.84 (▼ in FIG. 6), the appearance of the clothes 2 is not very preferable.

  Further, when the shadow depth S is 0.76 or more and 0.78 or less, even if the shadow depth S is the same size, the light from the pair of surface light sources 5 and 5 and the pair of point light sources 6 are used. , 6 has a color temperature of 4200K or more and 5000K or less, the appearance of the clothes 2 is more preferable.

  As described above, according to the first embodiment, for example, in a store such as a clothing store or a department store, when the customer (person 20) selects from the candidate clothes 2, the purchase intention is effectively improved, or the clothes 2 Since the appearance of the shadow depth S can be made favorable in order to express the material feeling of the garment 2 such as the fiber, type, weaving, and surface condition, the added value for the store side is high. An opportunity to have the customer (person 20) select the clothes 2 can be increased, and the customer (person 20) can select the clothes 2 without hesitation, and there is an effect that shopping is not painful.

  Further, when the color temperature is set to 4200K or more and 5000K, the appearance of the shadow depth S can be brought into a more preferable state.

  Furthermore, since the pair of surface light sources 5 and 5 and the pair of point light sources 6 and 6 are provided on both sides of the mirror 4, the fitting room illumination device 1 is installed so as not to interfere with fitting in the fitting room 3. be able to.
