The structure of＜circuit substrate 6 〉
＜electroluminescent lamp 7,7 ... structure
Electroluminescent lamp 7,7 ..., as shown in Figure 8, have separately in the LED28 and the incident as illuminating part of light taking-up side ejaculation white light and change with optical element 29, and be installed in the lamp installation side of circuit substrate 6 from the ejaculation light of this LED28 and to the light direction that the side is penetrated as the light direction converter section.Electroluminescent lamp 7,7 ... in size interval between adjacent 2 electroluminescent lamps 7,7 be set to about 100mm.
As shown in Figure 9, LED28, by the blue-led element 284 of the coloured light that turns blue with comprise potting resin 286 that the blue light that is sent by this blue-led element 284 excites the silicates fluorophor 285 that sends sodium yellow and be encapsulated in the packaging body 282 and constitute, and be configured in the element installation side of circuit substrate 6.And, constitute based on the mixing of the blue light that sends from blue-led element 284 and the sodium yellow that sends from fluorophor, penetrate the structure of white light as described above.As blue-led element 284, use by for example the emission wavelength zone being set at the blue-led element that the GaN based semiconductor compound of 450nm～460nm constitutes.As fluorophor 285, except using the silicates fluorophor, for example also can use YAG (Yttrium Aluminum Garnet: garnet class fluorophor such as fluorophor yttrium-aluminium-garnet).
Light direction conversion optical element 29, as shown in Figure 8, light entrance face 29A, reflection with light that incident penetrates from LED28 are from the light reflection surface 29B of the light of these light entrance face 29 incidents and the light emergence face 29C that the light by this light reflection surface 29B reflection is penetrated to side (tiltedly fore-and-aft direction), and be configured in the lamp installation side of circuit substrate 6, wholely form by transparent materials such as PMMA (lucite) resins.And, constitute when the light that penetrates from LED28 incides light entrance face 29A, make its most anaclasis, by light reflection surface 29B these refract light total reflections, and then from light emergence face 29C refraction, and from light reflection surface 29B (interface) to oblique the place ahead with tiltedly rear, side are penetrated.
Here, utilize Figure 10, the optical phenomena of the light that incides light reflection surface 29B is described.When light LB is the material of n1 when inciding refractive index and being the material of n2 from refractive index, according to Snell law, following relation is set up.
n1·sin(θ1)＝n2·sin(θ2)
Under the situation of n1＜n2, θ 1 '=90 °, θ 2 ' is called critical angle.When being the material of n2 when inciding refractive index and being the material of n1 with the angle more than the critical angle from refractive index, (light reflection surface 29B) carries out total reflection to incident ray LB at its interface.If is refractive index that the material of n1 is made as air (n1=1), is refractive index that the material (light direction conversion with optical element 29) of n2 is made as PMMA resin (n2=1.49), then critical angle θ 2 ' becomes θ 2 '=42.16 °.
Being provided with width (with the rectangular direction of length component direction) at face luminescence component 3 in light direction conversion with the light incident side end of optical element 29 goes up arranged side by side and can be crimped on the 29a of blade of a sword portion (as shown in Figure 3) on the end difference 14 to the both sides side of circuit substrate 6 in module body 5.On the light incident side end face of light direction conversion, be provided with the positioning pin chimeric (not shown) with pin-and-hole 6A, the 6B of circuit substrate 6 with optical element 29.The light direction conversion is implemented mirror finish with light entrance face 29A, light reflection surface 29B and the light emergence face 29C of optical element 29.As the material of light direction conversion, except using the PMMA resin, also can use Merlon and transparent resin material and clear glasses such as epoxy, silicone with optical element 29.In this case, the light direction conversion that is not limited to be made of transparent material also can be used to be implemented painted light direction conversion optical element with optical element 29.
Light entrance face 29A, as shown in Figure 8, constitute by the 1st light entrance face 29b and the 2nd light entrance face 29c, form by the recess 290 that forms the frusto-conical that enlarges gradually towards open end (light incident side end face) with side's side end formation of material (generally cylindrical body) at optical element.Recess 290 is formed by the spatial portion with the size that can take in LED28.Thus, the light at the 1st light entrance face 29b and LED28 takes out formation space G (G ≈ 0.3mm) between the face 28A.In addition, the light that penetrates from the side of LED28 incides the 2nd light entrance face 29c.Thus, the light (for example sodium yellow) that incides the 2nd plane of incidence 29c is spread, thereby can suppress the look inequality.
As shown in Figure 8, light reflection surface 29B forms by the funnelform recess 291 that the opposing party's side end setting that forms at optical element with material (generally cylindrical body) enlarges gradually towards open end (light taking-up side).And constituting can be with the structure of the light total reflection that arrives from light entrance face 29A.Light reflection surface 29B also can be equivalently as the part of rotation 2 curved surfaces, the particularly paraboloids of revolution or the hyperboloid of revolution.In order to improve reflection efficiency, also can light reflex face 29B implement the evaporation of the metal film of aluminium etc., or the electroless plating of nickel etc. is handled.Also can be formed on the recess of the opposition side opening of LED28 at the central part of light reflection surface 29B.Thus, the light from the central part (recess) of light reflection surface 29B can penetrate with the sensing angle of wide region.
The shape of light reflection surface 29B (funnelform outside) for example decides according to following simulated test.At first, as shown in figure 11, set roughly columned optical element and form axis direction size with material (PMMA resin) a (light direction conversion with the axis direction size of optical element 29) L, being set in simultaneously on the one side end face with the point on the central axis O is external diameter (maximum outside diameter of the light reflection surface 29B) D of the hypothesis circle at center.Then, forming from optical element with the opposite side end face of material a on the hypothesis face V1 of one side end face size of separation L1 (L〉L1), make from being preconfigured in optical element and form the light LB that penetrates with the LED on the central axis O of material a, carry out total reflection to become 42.16 ° (critical angles) above angle [alpha] with normal b.In this case, if will suppose the pip set of the light LB on the face V1, then these pips are the circumference configuration of D1 (D〉D1) along external diameter.And, carry out these on any hypothesis face parallel repeatedly and test forming, and gather whole pips with the side end face of material a with optical element.Set according to these pips forms light reflection surface 29B.
As shown in Figure 8, light emergence face 29C forms the periphery with uniform outer diameter.And, constitute as described above the structure of the light that reflects by light reflection surface 29B to oblique the place ahead and oblique rear and side ejaculation.In addition, penetrate efficient, adopt to be not easy to produce the structure of internal reflection and refraction, preferably minute surface in order to improve light.Form the situation of periphery although understand light emergence face 29C, but also can form polygon prism (triangular prism, quadrangular ...) the side.In order to make it have light diffusing, also can implement asperities processing to light emergence face 29C.Replace this asperities processing and in light direction is changed with optical element 29, sneak into light diffusing agent, also can improve light diffusing.
The structure of＜seal member 8 〉
(structure of light diffusing member 4)
As shown in Figure 1, light diffusion part 4 be configured in face luminescence component 3,3 ... light take out side, and be installed on the peristome of housing 2, it is formed by milky thin-plate member, and this milky thin-plate member is made of the resin material of having sneaked into light diffusing agent.And, constitute, make from face luminescence component 3,3 ... the light of ejaculation, spread the structure that sees through respectively by light and these mixed lights of the backplate 2C (assembly installed surface 2c) of housing 2 and side panel 2A, 2B (photo-emission part 2a, 2b) reflection.Light diffusing member 4 and face luminescence component 3,3 ... the interval be set to for example about 20mm.
Figure 12 (a)～(c) is the figure of expression light direction conversion with the position relation of optical element 29 and LED28, and Figure 12 (d) is the figure of the luminance of expression LED28 inside.
Shown in Figure 12 (a), LED28 by with void-free degree almost near the situation of light direction conversion with the light entrance face 29A side configuration of optical element 29 under, incide the light of light direction conversion with optical element 29, according to Snell law, direction optically focused in critical angle, carry out total reflection by photo-emission part 29B, light from the side takes out face 29C and penetrates towards the side, and diffusion towards periphery.In addition, applied under the situation of external force on the top of light direction conversion with optical element 29, LED28 also is applied in external force, might damage.
Shown in Figure 12 (b), exist under the situation in space between the light entrance face 29A with optical element 29 at LED28 and light direction conversion, because the incident expanded range, thus for the light full illumination that makes incident to light reflection surface 29B, must increase the diameter that optical element 29 is used in the light direction conversion.Under the situation that does not increase diameter, owing to the light that penetrates to direction from LED28 (because the distance of luminescent coating near level, so become the light of inclined to one side yellow), the light taking-up face 29C that is changed with optical element 29 by light direction carries out total reflection, penetrate from light reflection surface 29B, with sodium yellow optically focused on the central shaft of optical element 29,, can produce yellow part in the light direction conversion having constituted under the situation of area source by electroluminescent lamp 7 planes are disposed side by side.
Shown in Figure 12 (c), the bottom surface of changing with optical element 29 at light direction has recess 290, between the conversion of LED28 and light direction is with optical element 29, exist under the situation in sufficient space, even apply under the situation of external force on the top of light direction conversion with optical element 29, LED28 also can not be subjected to the influence of external force.
Owing to LED28 excites the sealing resin 286 of the fluorophor 285 that sends sodium yellow to seal by having sneaked into by the blue light that penetrates from blue-led element 284, so, according to the direction of the light that sends from blue-led element 284 by sealing resin 286, they are different by distance, therefore, the color difference of the light of ejaculation.That is, in Figure 12 (d), because the sealing resin 286 that passes through is thin, so the light of advancing to a direction becomes inclined to one side blue light.Because the sealing resin 286 that passes through is thick, so the light of advancing to the b direction becomes inclined to one side gold-tinted.Around the LED28 of light direction conversion, to form the mode of light entrance face with the light entrance face of optical element 29, the recess 290 that formation is made of the 1st light entrance face 29b and the 2nd light entrance face 29c, and by making sodium yellow composition near level from the 2nd light entrance face 29c incident, take out face 29C from light and penetrate and make its diffusion towards periphery, can make thus sodium yellow not optically focused on the top of light direction conversion with optical element 29.
The space between LED28 and the 1st light entrance face 29b is made as G, the diameter of LED28 (or width) when being made as D, the diameter of the 1st light entrance face 29b (or width) W is D＜W＜(D+3G) preferably, is more preferably D＜W＜(D+2G) or D＜W＜(D+G).
