The specific embodiment
Below, referring to figs. 1 through Fig. 5, embodiments of the present invention are described.In each figure, sometimes omit to represent the distribution annexation by wire etc.In addition, for same section mark same-sign, also the repetitive description thereof will be omitted.
The ligthing paraphernalia of present embodiment is: be installed to the ligthing paraphernalia that ordinary residence that ceiling lamp holder main body used is used, by carrying out indoor illumination from the light of light source portion radiation, described ceiling lamp holder main body is arranged at utensil installed surface and as distributor, described light source portion has a plurality of light-emitting components that are arranged on substrate.
In Fig. 1 to Fig. 4, ligthing paraphernalia possesses: body 1, light source portion 2, pervasion component (for example seeing through refraction member) 3, ignition device 4, ignition device cover 5, installation portion 6 and lampshade 7.And ligthing paraphernalia possesses: electrically and be connected mechanically to the adapter A of ceiling lamp holder main body Cb, described ceiling lamp holder main body Cb is arranged on the ceiling surface C as utensil installed surface.This kind of ligthing paraphernalia is the outward appearance that forms circular toroidal, and the shadow surface using front surface side as light, using rear side as the installed surface to ceiling surface C.
Light-emitting component 22 is LED, and is the LED encapsulation of surface installing type.This LED encapsulation is the Zhou Fangxiang along a plurality of circular substrates 21, that is, on the roughly circumference centered by installation portion 6, spreads all over multiple row and installs, and in present embodiment, be to spread all over inner circumferential side and these 2 row of outer circumferential side and install.And, for LED encapsulation, use illuminant colour for the LED encapsulation of LED encapsulation and bulb look of white in daytime, these LED encapsulation are alternately arranged, and the light-emitting component 22 of the adjacency of each row is that sky is opened roughly and uniformly-spaced set.Electric current by the LED encapsulation to the white in this of flowing through and the LED encapsulation of bulb look etc. is adjusted in daytime, can mix colours.
In addition, at specific substrate 21 (being right side in Fig. 3), the light-emitting component 22a that normal bright lamp is used is installed.For this light-emitting component 22a, use with the LED that is mounted to the bulb look in circular main light source and encapsulate identical LED encapsulation.Thus, realize the sharing of member.
In addition, light-emitting component 22 may not be mounted to multiple row.For example, also can be mounted to 1 row along Zhou Fangxiang.Can suitably set according to required output columns or the number of light-emitting component 22.
LED encapsulation comprises substantially: LED chip (chip), is provided in the body being formed by pottery or synthetic resin; And epoxy is the translucent resin of molded (mold) use of resin or silicone (silicone) resin etc., seal this LED chip.LED chip is the blue LED chip that sends blue light.In translucent resin, for can outgoing white in daytime or the light of bulb look, and have sneaked into fluorophor.
In addition, LED both can directly be installed on substrate 21 by LED chip, and, also can be mounted to the LED of bullet cut, mounting means or form are not particularly limited.
And lens component is in roughly circular inner circumferential side part and outer circumferential side part, with light-emitting component 22 opposite to each other, be along the circumferential direction formed with continuously 2 for chevron and section shape be fixing projecting strip part 31.Therefore, the groove 32 of U-shaped is to configure opposite to each other with a plurality of light-emitting components 22, and a plurality of light-emitting components 22 become in the groove 32 that is incorporated in U-shaped and capped state.
And then, from these projecting strip parts 31, be formed with the par 33 that broad ways is extended, thus, whole of covered substrate 21.
According to the lens component forming in this way, as shown in Figure 5, from a plurality of light-emitting component 22 outgoing only: utilize projecting strip part 31, and mainly to interior Zhou Fangxiang and peripheral direction diffusion on circumference and radiate.That is, from light-emitting component 22 outgoing only: mainly towards take, dispose the radial direction diffusion radiation that the circular center of light-emitting component 22 is initial point.
Therefore, scioptics member, can improve from the uniformity of the irradiation light of the light of a plurality of light-emitting component 22 outgoing.And then, can suppress the granular sensation of the brightness based on each light-emitting component 22.Now, comparatively it is desirable to, the light distribution angle of realizing by diffusion is set as to 120 degree left and right, degree～160.
And, at pervasion component 3, be formed with par 33 with whole of covered substrate 21, so charging part is covered and is protected by the pervasion component 3 with heavy insulation performance.
In addition, pervasion component 3 also can not be formed integrally as roughly circular.For example, pervasion component 3 also can be corresponding to the substrate 21 through cutting apart, for these substrates 21 each and cut apart and form.Now, for each of a plurality of light-emitting components 22 that is arranged on a substrate 21, and by pervasion component 3, covered continuously.
And pervasion component 3 is not limited to lens component, also applicable prism (prism) etc., so that this pervasion component 3 possesses the anisotropy of the range of exposures of light-emitting component 22.
The light source portion 2 forming in the above described manner as Fig. 4 and Fig. 5 typically as shown in, substrate 21 is positioned at installation portion 6 around, the installed surface of light-emitting component 22 is towards front surface side, i.e. direction of illumination downward and setting.And the rear side of substrate 21 is to contact and install with the mode formation face connecting airtight with the par 12 of the inner face side of body 1.Particularly, pervasion component 3 stresses to fold from the front surface of substrate 21, and by the fixture such as screw S etc. and this pervasion component 3 is installed on to body 1, thus substrate 21 by double team between body 1 and pervasion component 3 and be subject to pressing fixing.That is, by 1 screw S, come fastening base 21 and pervasion component 3.
Therefore, substrate 21 is and body 1 thermal, from the heat of substrate 21, from rear side, conducts to body 1 and dispels the heat.In addition, substrate 21 contacts the situation of whole the contact body 1 that is not limited to substrate 21 with the face of body 1.Also can be local face contact.
In addition, the par 33 in pervasion component 3 is to contact with the mode formation face connecting airtight with the installed surface side of substrate 21, so heat energy is enough from the installed surface side of substrate 21, is passed to pervasion component 3, and distributes via pervasion component 3.That is, also can dispel the heat from the front surface side of substrate 21.
As shown in Figures 2 to 4, ignition device 4 possesses: circuit substrate 41 and the circuit component 42 that is installed on the integrated circuit for control (Integrated Circuit, IC), transformer (transformer), capacitor (condenser) etc. of this circuit substrate 41.Circuit substrate 41 be surround installation portion 6 surrounding mode and form roughly circular-arcly, and be electrically connected adapter A side, and be connected in commercial ac power source via adapter A.Therefore, ignition device 4 is accepted this AC power and is generated direct current output, and via wire, this direct current output is supplied to light-emitting component 22, with control that light-emitting component 22 is lit a lamp.
This kind of ignition device 4 is to be provided between installation portion 6 and light source portion 2 (being substrate 21).
As shown in Figures 2 and 4, ignition device cover 5 is to form roughly short cylinder shape by the metal material of cold-rolled steel sheet etc., and is installed on body 1 to cover the mode of ignition device 4.Sidewall 51 is in the mode expanding towards rear side, to be skewed; In front side wall 52, in the mode corresponding with installation portion 6, be formed with peristome 53.Therefore, from a part of light of light-emitting component 22 outgoing, by sidewall 51, reflected forward face side and be utilized effectively.And, at the periphery of this peristome 53, be formed with the circular-arc guide recess that becomes concavity towards rear side.
In addition, installation portion 6 may not be the member that is known as adapter guide portion etc.For example, also can be formed in the opening of body 1 grade, mainly refer to: with ceiling lamp holder main body Cb as distributor in opposite directions and member or part that adapter A is engaged.
And lampshade 7 is the modes that cover the front surface side of the body 1 that comprises light source portion 2, and be releasably arranged on the periphery edge of body 1.Particularly, by rotating lampshade 7, the not shown cover installed part that what lampshade 7 is set is sticked in to lampshade and is subject to fastener 75 and installs, described lampshade is subject to fastener 75 to be provided in the recess 14 of the periphery edge of body 1.
At the inner face of lampshade 7, be formed with printing opacity control part 71.This printing opacity control part 71 is mix the mode existing and form with the relatively little region 71a of the transmitance of light, the region 71b relatively large with the transmitance of light.
Specifically, printing opacity control part 71 is implement silk-screen (silk print) and form in the inner face side of lampshade 7, at the relatively little region 71a of the transmitance of light, is formed with the relatively large region 71b of transmitance of a plurality of light.The relatively little region 71a of transmitance of light is for example the part that is coated with white ink (ink), the relatively large region 71b of transmitance of light is the part of uncoated adularescent ink, this part is in being coated with the region of white ink, scatters the mode of a plurality of (numerous) roundlet shape and forms.
That is,, in the inner face side of lampshade 7, the part of residual a plurality of roundlet shapes is carried out the ink of coating and printing white.
Therefore, the seeing through of light of irradiating to the relatively little region 71a of the transmitance of light is suppressed, and to the relatively large region 71b of the transmitance of light, the seeing through of light of irradiating to the part of a plurality of roundlet shapes, can carry out well.
Herein, relatively little, relatively large the referring to of transmitance of light: with the relativeness of region 71a, 71b, for example, the relatively little region 71a of transmitance of light has the transmitance of regulation and the situation that forms, irradiation light from light source portion 2 is spread, and irradiate shadow surface downwards, but sometimes also can be hardly, see through, do not see through in fact the situation forming.
That is, the region beyond the relatively large region 71b of the transmitance of the light of lampshade is: have light transmission, be creamy white and possess diffusivity and form.
In addition, when the moulding of this kind of lampshade 7, it is the rear side at the sheet material (sheet) of acrylic resin as its material etc., to form the mode of the part (part of uncoated ink) of a plurality of roundlet shapes, implement serigraphy, subsequently, the regulation shape that pressure forming (press forming) is circular shape is made.
And then, the relation that the relatively little region 71a region 71b relatively large with the transmitance of light of transmitance of light also can be contrary and forming.That is,, as the relatively little region of the transmitance of light, also can form the part of a plurality of roundlet shapes.Now, as long as suitably set the diameter dimension of roundlet shape according to design.
And then, also can, by running through the inside and outside aperture of lampshade 7, form the relatively large region 71b of transmitance of light.Now, also can so that relatively little region, the region large with the transmitance of light of the transmitance of light mix the mode existing and form.
So, with the relatively little region 71a of the transmitance of light, the region 71b relatively large with the transmitance of light mixes the mode existing and the structure forming can adopt various structures, is not distinctly defined as specific structure.
In addition, the distance between pervasion component 3 and lampshade 7 is set to 20mm～60mm, is preferably set to 30mm～50mm.Thus, the uniformity of irradiating light becomes well, and the heat that conducts to pervasion component 3 from the installed surface side of substrate 21 is: via lampshade 7, effectively dispel the heat.
And then lampshade 7 is transparent bases of comprising minute surface on surface, such as the inner face at the high base material of the transparent permeabilities such as acrylic resin, be formed with the light-transmissive film that comprises resin sheet material with a plurality of peristome 71b.In addition, for transparent acrylic resin, comparatively it is desirable to the inside transmitance of this acrylic resin and comprise the member that the outside transmitance on surface (interface) is high or comprise that surface (interface) comprises material optical mirror plane and gloss, that permeability is high.That is, transparent acrylic resin is so long as diffusivity is low, and can via lampshade 7 perspectives, be positioned at the base material of the article in its place ahead, also can be surface form as concavo-convex through prism processor.
The light-transmissive film 71a that is formed on lampshade 7 inner faces is such as being to be formed with white film by serigraphy (silk screenprint) etc.A plurality of peristome 71b that form at this light-transmissive film 71a are: the size that forms diameter 0.5mm～5mm left and right.If this peristome 71b is less than 0.5mm, lampshade 7 is being installed under the state of apparatus body, the light that passes peristome 71b will die down, and in the ratio that links the light-emitting component 22 existing on the straight line of viewpoint and peristome 71b, will tail off.Therefore, be difficult to obtain via peristome 71b the light that light-emitting component 22 glitters dazzlingly.On the other hand, if peristome 71b is more than 5mm, the doubt that exists a plurality of light-emitting components 22 to irradiate from 1 peristome 71b, therefore compared to the sense of glittering, more can allow people feel to dazzle the eyes sense.Therefore, comparatively it is desirable to, the peristome 71b that does not preferably implement serigraphy is less than light-emitting component 22, and opening footpath the best of peristome 71b is 0.7mm～2mm left and right.
And in the present embodiment, the formation region of this peristome 71b is: be formed at least the scope that covers the light-emitting component 22 installed with Zhou Fangxiang along circular substrate region in opposite directions.That is, at the middle section being surrounded by light-emitting component 22, be the middle section of lampshade 7, do not form peristome 71b.And, extensively cover peristome 71b with all size light-emitting component 22 region in opposite directions, that form along the Zhou Fangxiang of lampshade 7 and be and form (random) and densely at random.In being formed with the region of peristome 71b, peristome 71b is preferably 0.3%～0.6% with respect to the ratio of light-transmissive film.If peristome 71b is less than 0.3%, on the straight line that links viewpoint and peristome 71b, do not exist the ratio of light-emitting component 22 to uprise, therefore cannot feel that the peristome 71b of light becomes many, the quantity of luminous opening tails off glaringly.On the other hand, if peristome 71b surpasses 0.6%, feel that the peristome 71b of light can be very many, and the peristome 71b of imperceptible light tails off.Therefore, compared to the range estimation brokenly causing by moving view point to the sense of glittering that independently flicker of a plurality of peristome 71b is felt, flicker number of times tails off and feels and dazzle the eyes sense, feels that uncomfortable doubt improves.Therefore, can say: the formation region of peristome 71b is preferably 0.3%～0.6% with respect to light-transmissive film.And the ratio of the peristome 71b in lampshade 7 integral body in present embodiment is approximately 0.5%, in the situation that middle section does not form peristome 71b, the peristome 71b in lampshade 7 integral body is preferably 0.4% left and right.
In addition, the transmitance of the light-transmissive film that is formed with serigraphy of lampshade 7, comparatively it is desirable to below 40%～80%.In present embodiment, the transmitance of wavelength 380nm～780nm is formed to 60% left and right.If transmitance is below 40%, under illumination low, luminous flux is too low, thereby is difficult to use as ligthing paraphernalia.On the contrary, if transmitance is more than 80%, under illumination high, light beam is also abundant, comes the light of self-emission device 22 that efficiency is irradiated well to shadow surface.But, peristome 71b (light-emitting surface brightness) is poor the diminishing of luminance difference, illumination in photic zone 71a region (background luminance) with serigraphy region, therefore, cannot meet the surcharge effect of glittering dazzlingly that the light because spilling from a plurality of openings causes.
Like this, following ligthing paraphernalia is provided, must meet these conditions, described ligthing paraphernalia is guaranteed as the required illumination of general lighting utensil, and possess the sense of glittering, this sense of glittering sees, comes the irradiation light of self-emission device 22 to be caused by the peristome 71b without serigraphy via Transparent lamp shade 7.
This kind of lampshade 7 is the modes that cover the front surface side of the body 1 that comprises light source portion 2, and is releasably installed on the periphery edge of body 1.Particularly, by rotating lampshade 7, the not shown cover installed part that is arranged at lampshade 7 is sticked in to lampshade and is subject to fastener 75 and installs, described lampshade is subject to fastener 75 to be equipped on the recess 14 of the periphery edge of body 1.
In addition, with the peristome 71b of lampshade 7, mix the structure that the mode that exists forms with photic zone 71a, can adopt various structures, be not distinctly defined in specific structure.For example, also can adopt the configuration that is arranged with systematicness of peristome 71b.And then, in position in opposite directions, the region that is formed with peristome 71b with lampshade 7, also can implement Surface Machining to become the prism processing of minute surface.
Adapter A is by being located at the hook of upper surface side, and electrically and be connected mechanically to the part of the ceiling lamp holder main body Cb that is arranged on ceiling surface C, and be roughly cylindric; And, in the both sides of perisporium, with the spring by built-in (spring), all the time to the side-prominent mode of periphery, and be provided with a pair of fastener A1.This fastener A1 is operated and is submerged by the action bars (lever) for being arranged on lower face side.And, from this adapter A, derive and have the power line (cord) that is connected to described ignition device 4, and be connected (with reference to Fig. 3) via connector with ignition device 4.
Next, with reference to Fig. 4, illustrate, ligthing paraphernalia is to the installment state of ceiling surface C.First, by adapter A electrically and be connected mechanically to the ceiling lamp holder main body Cb setting in advance at ceiling surface C.From this state, on one side using the snap openings of the adapter guide portion as installation portion 6 61 alignment adapter A, fitting operation with pushing away on hand apparatus body, until the fastener A1 of adapter A positively snaps into the snap openings 61 of adapter guide portion, thereby is carried out from below in one side.Then, lampshade 7 is mounted to body 1.This installation state is the state shown in Fig. 4, and now, elastic component 15 is situated between every between ceiling surface C and the rear side of body 1 with tightlock status, and ligthing paraphernalia becomes the stationary state that is fixed on ceiling surface C.
And when dismounting ligthing paraphernalia, dismounting lampshade 7, operates being arranged at the action bars of adapter A, to remove the engaging of the fastener A1 of adapter A, thus detachable lighting utensil.
At ligthing paraphernalia, be installed under the installment state of ceiling surface C, when ignition device 4 is supplied with to electric power, via substrate 21, to light-emitting component 22 energisings, each light-emitting component 22 lit a lamp.From light-emitting component 22 outgoing only: by covering continuously the pervasion component 3 of a plurality of light-emitting components 22, towards radial direction, spread, and be sidelong and penetrate towards front surface.For radiating the light of face side forward, towards the light of the printing opacity control part 72 of lampshade 7, mainly see through the relatively large region 71b of transmitances a plurality of roundlet shapes, light, thereby see through lampshade 7 and irradiate.Now, from light-emitting component 22, irradiate only: by pervasion component 3 be partial to (deflection), disperse, reflection, and irradiate to foreign side via lampshade 7 towards direct of travel separately.
When looking up this kind of irradiation light time from the below of lighting device, by by looking at light-emitting component 22 straight with the relatively large region 71b of light-emitting component 22 spread configurations transmitance on straight line, light, thereby feel strong light.On the other hand, even in the situation that link on the straight line of the relatively large region 71b of the transmitance of light and fulcrum and do not have light source, also can the light of light-emitting component 22 be spread by pervasion component, thereby can feel faint light.By pervasion component is made as to lens, can look at from various angles the light of self-emission device 22 straight, therefore can improve its frequency of glittering or intensity.
According to this kind of structure, be constructed as follows described peristome 71b, if the region 71b that is: viewpoint, light-emitting component 22 and transmitance are relatively high is positioned on straight line, feel strong light, if the relatively large region 71b of the diffused light of carrying out self-emission device 22, viewpoint and transmitance after pervasion component diffusion is positioned on straight line, feeling glitters feels weak light, if there is not light-emitting component 22 and carry out the diffused light of self-emission device on the straight line that links the relatively large region 71b of transmitance and viewpoint, the imperceptible light glittering.
Like this, no matter be in the situation that looking up lighting device, or in the situation that observe from the side of lighting device, all mix have see light-emitting component 22 for the light of point-like and the part of glittering dazzlingly with strong light, see part that light-emitting component 22 glitters dazzlingly with faint light, and imperceptible part of glittering, under the state that the dazzle that therefore, can cause at light-emitting component 22 is suppressed, estimate.In addition, by moving view point, feel that the region of glittering makes respectively light intensity change or flicker repeatedly, thereby the position of observing by change can obtain each position and show dazzlingly, brokenly the decorative effect of the intensity of glittering.And then, by the light of the relatively little region 71a of the transmitance through light, can realize the raising of the uniformity of irradiating light.And then, in present embodiment, by using double-colored different light-emitting component 22, can see that a plurality of peristome 71b mix the white light of white in daytime and the light of bulb look and exist and flicker dazzlingly.Thus, aspect design, can obtain more excellent effect.
On the other hand, because the rear side of substrate 21 is to contact with 1 of body, therefore, the heat producing from light-emitting component 22 will conduct to body 1 effectively, and dispel the heat with large area.And, near the outer circumferential side of substrate 21, along the periphery of substrate 21, be formed with order difference part 13, therefore can carry out increasing heat radiation area by this order difference part 13, thereby can improve the radiating effect of body 1 peripheral part.In addition, this order difference part 13 can be brought into play the stiffening effect of body 1.
And ignition device 4 is to be provided between installation portion 6 and substrate 21, therefore, alleviates ignition device 4 and be subject to the hot impact from substrate 21.This is that the heat due to substrate 21 is: exist towards the peripheral direction of body 1 and conduct and the tendency of dispelling the heat causes.
In addition, the par 33 of pervasion component 3 is to contact with the installed surface side formation face of substrate 21, therefore, also can from the installed surface side of substrate 21 via pervasion component 3 in the past face side dispel the heat.And, now, whole of pervasion component 3 covered substrates 21, so charging part is protected.
As mentioned above, according to present embodiment, when looking up lighting device, can see that light is designed and the light of spot light glitters dazzlingly, can obtain decorative effect, thereby improve performing effect.And then, a kind of ligthing paraphernalia can be provided, by the pervasion component 3 of covering luminous element 22 is continuously set, thereby can realize the raising of the uniformity of irradiating light.
In addition, the present invention is not limited to the structure of the respective embodiments described above, in the scope of purport that does not depart from invention, can carry out various distortion.For example, the shape of the region 71b that transmitance printing opacity control part 71, light is relatively large is not limited to circle, and then to carry out the way of patterning also applicable to being formed on the hole of the printing opacity control part on whole lampshade.
