［ lighting device ］
Fig. 4 is the concise and to the point cutaway view of the structure of the related lighting device of explanation embodiment.Lighting device 20 possesses: lighting source 21; Illumination housing 22, this illumination housing 22 covers the light-emitting area side of lighting source 21; Fixed station 23, is installed on lighting device 20 by this fixed station 23 internal face of refrigerating chamber 2; And diffusion sheet material 26, this diffusion sheet material 26 is located between lighting source 21 and illumination housing 22.
Lighting source 21 is by LED(light-emitting component) form, a plurality of lighting sources 21 are installed on substrate.The lighting source 21 that is installed on substrate is installed on fixed station 23 by light source support 24.For lighting source 21, its light-emitting area is towards downside, thereby roughly light downward irradiated.
Illumination housing 22 is formed with in the inside of himself to be taken in the accommodation space of lighting source 21 and the light-emitting area of lighting source 21 is covered.Illumination housing 22 is located at a side (being the downside of lighting source 21 in present embodiment) of facing with the light-emitting area of lighting source 21, thereby this illumination housing 22 covers lighting source 21 from below, lighting source 21 is accommodated between this illumination housing 22 and fixed station 23.Illumination housing 22 consists of the transparent synthetic resin material for light transmission.Inner surface and the outer surface of illumination housing 22 are tabular surface.Illumination housing 22 is installed on fixed station 23 by comprising the illumination housing maintaining part 25 of the engaging pawl that is formed at fixed station 23.
Diffusion sheet material 26 is installed on the inner surface of illumination housing 22, that is: this diffusion sheet material 26 is installed on and opposed of the light-emitting area of lighting source 21.Diffusion sheet material 26 has reduced the directionality of the light penetrating from lighting source 21, has and has realized for example such luminous function of face of fluorescent lamp.For example, at thickness, be the single or double of the transparent sheet material of 0.2mm～1mm left and right, utilize have to light reflect, the ink of the character of absorption or scattering implements printing so that light spreads, can make thus and spread sheet material 26.By adjusting the concentration of diffusion sheet material 26 being implemented to the rear formed decorative pattern (printed patterns) of printing and ink, can adjust the disperse state to light of diffusion sheet material 26.In addition, by implementing to make light that the printed on both sides of diffusion occurs to diffusion sheet material 26, compare with being printed on one side, make light with higher efficiency diffusion.The material of sheet material self of diffusion sheet material 26 can be used the resin material with the high grade of transparency, such as using PC(Merlon), PET(polyethylene terephthalate) etc.According to required diffusion concentration, adjust the concentration of diffusion material (diffusion ink) or the thickness of particle, and at diffusion sheet material 26, the diffusion material after adjusting is for example applied and become band.Preferably, for putting on the diffusion material (diffusion ink) that spreads sheet material 26, within the scope of the concentration of equal extent or the coating of particle thickness, in order to suppress interference fringe and polarisation, described diffusion material is carried out to random arrangement so that it does not have specific decorative pattern.
Herein, to having used the directional characteristic of the lighting source 21 of light emitting diode to describe.Fig. 9 is the figure of an example that the directional characteristic of light emitting diode is shown.As shown in Figure 9, generally, for light emitting diode, the light (optical axis) penetrating towards the direction vertical with light emitting diode has maximum intensity.In addition, in the situation that the characteristic of the intensity of illumination of light emitting diode is not clear, by for example the intensity of illumination of light emitting diode is measured and can be measured directional characteristic as shown in Figure 10.Figure 10 is the figure that the measuring method of the directional characteristic of light emitting diode is described.As shown in figure 10, light intensity measuring instrument 30 is disposed to the position that separates constant distance L with respect to the lighting source 21 that has used light emitting diode, utilizes 30 pairs of intensities of illumination of light intensity measuring instrument to measure.And the plurality of positions on the circumference that is L at the radius along take centered by lighting source 21, utilizes 30 pairs of intensities of illumination of light intensity measuring instrument to measure.By like this intensity of illumination being measured, if the intensity of illumination on the optical axis of lighting source 21 is made as to 100%, can copies the example of Fig. 9 and express the intensity of illumination in each angle of light intensity measuring instrument 30 and 20 one-tenth of lighting sources.As shown in Figure 9, generally speaking, the light that light emitting diode sends has the higher character of craspedodrome.
Fig. 5 is the concise and to the point cutaway view of major part of refrigerator of the position relationship of the related lighting device of explanation embodiment and upper strata shelf.In Fig. 5, with Reference numeral 60, represent the optical axis of the related lighting source of present embodiment 21, and, also show in the lump the range of exposures of lighting source 21.In addition, in Fig. 5, take the light source with the directional characteristic shown in Fig. 9 is example as the situation of lighting source 21, for from the emitted light of lighting source 21, according to lighting source 21 and the position relationship of upper strata shelf 11, has defined these 5 scopes of scope A～scope E.In addition, in Fig. 5, paper right side is the front face side (reveal) of refrigerating chamber 2, and paper left side is rear side.
Scope A is the scope from line 62 to line 61, and wherein, this line 62 tilts 60 ° towards rear side with respect to the optical axis 60 of lighting source 21, and this line 61 tilts 80 ° towards rear side with respect to optical axis 60.Line 61 or the line that the trailing edge of lighting source 21 and upper strata shelf 11 is linked, and, line 62 is still stipulated the line of rear end of the illumination zone of lighting source 21, and therefore, scope A can be called from the scope of the back end of rear end to the upper strata shelf 11 of the illumination zone of lighting source 21.
Scope B is from the optical axis 60 of lighting source 21 to the scope towards the line 62 of 60 ° of rear side inclinations with respect to this optical axis 60.
Scope C is from the optical axis 60 of lighting source 21 to the scope with the line 63 of the leading edge link of upper strata shelf 11 by lighting source 21.
Scope D is the scope from line 63 to line 64, and wherein, this line 63 links lighting source 21 and the leading edge of upper strata shelf 11, and this line 64 rolls oblique 60 ° above with respect to optical axis 60 courts.
Scope E is the scope from line 64 to line 65, and wherein, this line 64 rolls oblique 60 ° above with respect to optical axis 60 courts of lighting source 21, and this line 65 rolls oblique 80 ° above with respect to optical axis 60 courts.
At scope D and scope E, the user who opens the door of refrigerating chamber 2 can look at lighting source 21 straight.In addition, at scope A, because the light intensity penetrating from lighting source 21 is optical axis below 50%, therefore, the Visual Confirmation of food reduces, and can make user feel that the inboard of refrigerating chamber 2 is darker.
Therefore, in the present embodiment, by diffusion sheet material 26 be dimensioned to make light be mapped to the scope from scope A to scope E.Thus, realized the diffusion of the light on scope A, can guarantee until the intensity of illumination at the rear of upper strata shelf 11, thereby can improve the dark sensation that user experiences, and can improve Visual Confirmation.In addition, owing to making to be diffused into scope D and scope E from the light of scope B and scope C by diffusion sheet material 26, therefore can suppress the sense of discomfort of bringing to user because of dazzling.In addition, the size restrictions of diffusion sheet material 26, for can make light be irradiated to the size of scope E from scope A, can be reduced to the material cost of diffusion sheet material 26 thus.
Diffusion patterned and the diffusion concentration that is arranged at the diffusion sheet material 26 of lighting device 20 can be decided by lighting source 21 and the diffusion position relationship of sheet material 26 and the position relationship of lighting source and shelf.Generally, as shown in Figure 9, for having used the lighting source 21 of light emitting diode, the light (optical axis) penetrating towards the direction vertical with lighting source 21 has maximum intensity.
Therefore, take and eliminate because user feels the dazzling discomfort causing and realize intensity of illumination illumination to be uniformly object, adjust decorative pattern and the concentration of the diffusion printing that diffusion sheet material 26 is implemented.Particularly, for example implement as follows printing: for with respect to optical axis towards the front openings of refrigerating chamber 2 roll in oblique direction, advance, from for the diffusion concentration in the crossing region of the light of lighting source 21, make it be less than the diffusion concentration with the region of the optical axis intersection of lighting source 21.Make with the diffusion concentration in the region of the optical axis intersection of lighting source 21 maximumly, and it is less to make diffusion concentration more tend to the front openings side of refrigerating chamber 2, thereby, diffusion concentration is carried out to staged or non-stepped adjustment.Thus, strengthened the diffusion of the high light on the optical axis direction of lighting source 21, in the relatively low region of exposure intensity, diffusion concentration reduces and has maintained permeability, therefore, can make the illumination in refrigerating chamber 2 more approach uniform state.
In addition, when the diffusion concentration of the diffusion sheet material 26 on optical axis is set as to 100%, in back side direction in refrigerating chamber 2, also make accordingly diffusion concentration reduce with exposure intensity characteristic, in the angle of having strengthened thus the diffusion of the high light under optical axis and having weakened at light, kept permeability, thus can be to irradiating uniformly in refrigerator.
In addition, can with dull gradient, diffusion concentration not adjusted yet, when the diffusion concentration of the diffusion sheet material 26 on optical axis is set as to 100%, be equivalent to, in the angle of 60% intensity of illumination, the diffusion concentration of described diffusion sheet material 26 also can be made as to 60%.Thus, can suppress the dazzling sense that user feels, and can suppress the uneven degree of throwing light on, therefore, the aesthetic property of the outward appearance of lighting device 20 is also improved.
Next, the mounting structure of installing to illumination housing 22 of diffusion sheet material 26 is described.
Fig. 6 is that the master of the related illumination housing of embodiment and diffusion sheet material looks cutaway view.Fig. 7 is the enlarged drawing of the X part of Fig. 6.
The mode that the related diffusion sheet material 26 of present embodiment contacts with the inner surface of illumination housing 22 with its surface and be installed on the housing 22 that throws light on.Do not use adhesive, but utilize clamp structure or locking strutcture and diffusion sheet material 26 is installed on to illumination housing 22.In the present embodiment, in the inner side of illumination housing 22, be provided with sheet material maintaining part 27, this sheet material maintaining part 27 is by making the inner surface that spreads the surface of sheet material 26 and the housing 22 that throws light on contact and diffusion sheet material 26 is kept.Sheet material maintaining part 27 is outstanding pawl or the ribs of inner surface from illumination housing 22.Diffusion sheet material 26 is inserted into pawl or the rib of sheet material protection portion 27, thereby between sheet material maintaining part 27 and the inner surface of illumination housing 22, diffusion sheet material 26 is clamped to maintenance.
By this sheet material maintaining part 27 is set, do not use adhesive materials such as two-sided tape, paste diffusion sheet material 26 can be installed on to illumination housing 22 yet.Owing to not using adhesive in the process diffusion sheet material 26 being fixed on to illumination housing 22, therefore can suppress the generation probability of the bad phenomenon of the fee of material of adhesive means, the operating cost that adhesive means is pasted and mistake stickup.In addition, while having used adhesive in the installation process at diffusion sheet material 26, the illumination housing 22 forming because of the transparent material by for light transmission sometimes produces paste vestige and bubble causes cosmetic look variation, yet, according to present embodiment, above-mentioned this situation can not occur, and the cosmetic look of lighting device 20 is good.In addition, while having used adhesive in the installation process at diffusion sheet material 26, because spreading the deviation of the thickness of the air layer between sheet material 26 and illumination housing 22, cause the visual performance of light to produce inequality sometimes, yet, according to present embodiment, can weaken the uneven degree of the visual performance of this light.
In addition, the concrete structure of the sheet material maintaining part 27 shown in Fig. 6, Fig. 7 is an example, can adopt other clamp structure or the locking strutcture that does not use adhesive.For example, also can arrange from the outstanding pawl of inner surface of illumination housing 22, and make a part of engaging of spreading sheet material 26 between the front end of this pawl and the inner surface of illumination housing 22.In addition, also can aperture be set at diffusion sheet material 26, and can be inserted into above-mentioned aperture and be formed with the engaging pawl preventing from the projection of aperture disengaging in the inner surface setting of illumination housing 22.
Fig. 8 is the front view of the related illumination housing of embodiment and diffusion sheet material.Main looking while observing, illumination housing 22 and diffusion sheet material 26 are both ends on long side direction than the central portion circular arc of lateral bend (round) shape more upward.Like this, although illumination housing 22 and diffusion sheet material 26 are circular shape, curvature is different, and the curvature of diffusion sheet material 26 is less than the curvature of illumination housing 22.Although be not installed under the state of illumination housing 22 both curvature at diffusion sheet material 26 different, but, when diffusion sheet material 26 is assemblied in to the inner surface of illumination housing 22, diffusion sheet material 26 is pressed and itself and the inner surface of illumination housing 22 are connected airtight, thereby can suppress to produce gap between the two.The difference of diffusion sheet material 26 and the curvature of illumination housing 22 is on the basis of moulding deviation of having considered them and determine, therefore, even if for example at illumination housing 22 because moulding deviation produces bending, the housing 22 that also can suppress to throw light on produces gap with spreading between sheet material 26.Owing to can being suppressed at diffusion sheet material 26, produce gap with illumination between housing 22, therefore can suppress the diffusion deviation of the light that causes because of generation gap and spread bad, thereby can reduce manufacturing cost.When the two-sided enforcement of diffusion sheet material 26 is printed, compare with being printed on one side, can make light spread more efficiently, and, because not using adhesive in the installation process at diffusion sheet material 26, therefore can not make its efficient diffusion effect impaired and can maintain this diffusion effect.
As mentioned above, according to present embodiment, between illumination housing 22 and lighting source 21, be provided with the diffusion sheet material 26 making from the light diffusion of lighting source 21.And, at diffusion sheet material 26, according to itself and the position relationship of lighting source 21, implement different diffusion printings.Therefore, can obtain the illumination that can make in refrigerating chamber 2 and approach uniform lighting device 20.
Figure 11 is the concise and to the point cutaway view of the related lighting device of comparative example.In Figure 11, for convenience of explanation, the structure corresponding with present embodiment marked to identical Reference numeral.As shown in figure 11, in the past, proposing had following scheme: by the inner surface of illumination housing 22 being implemented to fold processing etc., form concavo-convexly 31, make thus light spread.Yet the moulding of concavo-convex 31 processing and illumination housing 22 need to spend money and time, sometimes also can produce the problem of the moulding aspect of weld seam (weld), current mark or shrinkage cavity and so on.Yet, in the present embodiment, inner surface at illumination housing 22 does not arrange concavo-convex and makes this inner surface keep smooth, therefore can reduce the bad phenomenon causing because of moulding of illumination housing 22, thereby can reduce, manufactures illumination required expense and the time of housing 22.Even if in the situation that the specification relevant to illumination in refrigerating chamber 2 produces change, according to present embodiment, also can deal with by the printing change of diffusion sheet material 26 and the replacing of diffusion sheet material 26.When picture changes concavo-convex 31 shape of illumination housing 22 as shown in Figure 11, need to again make mould, thereby cause development cost and construction cycle to increase, yet, according to present embodiment, compare with the lighting device of Figure 11, can reduce development cost and construction cycle, thereby can suppress manufacturing cost.In addition, in the development process of the lighting device 20 in refrigerating chamber 2, prepare in advance and make decorative pattern light diffusion, printing and the different a plurality of diffusion sheet materials 26 of printing concentration, by changing these diffusion sheet materials, actual illumination condition can be confirmed, the modification situation in development process can be cut down significantly thus.
In addition, as shown in comparative example, when when illumination housing 22 is provided with concavo-convex 31, in order to obtain diffusion effect, need to guarantee lighting source 21 and the distance of illumination between housing 22, thereby make sometimes lighting device 20 become to maximize and the accommodation space in compression refrigerating chamber 2, the accommodation space of thermal insulation barriers.But, according to present embodiment, by adjusting the printing that diffusion sheet material 26 is implemented, can control the diffusion concentration of light, therefore, compare with comparative example, can make lighting device 20 miniaturization that becomes.Therefore, can improve the cosmetic look of lighting device 20, and can expand the accommodation space in refrigerating chamber 2 and improve user's ease of use, in addition, due to by guaranteeing that the accommodation space of thermal insulation barriers has obtained required heat-proof quality, the increase of power consumption that therefore can also freezing-inhibiting refrigerator 100.
In addition, for the illumination housing 22 forming for synthetic resin is carried out to moulding, be difficult to form there is gradient, that solid manifests is concavo-convex 31, but but than being easier to, diffusion sheet material 26 is implemented to the printing that has gradient, solid manifests.Therefore, the special visual effect of illumination can be obtained, in addition, the cosmetic look of lighting device 20 can also be improved.
