In addition, in the present embodiment, body 1 is suitable with base plate, can refer to housing, reflecting plate or substrate.In general, refer to setting directly or indirectly member or the part of main light source section 2, be not particularly limited interpretation.

Such as Fig. 2, Fig. 4 and shown in Figure 7, main light source section 2 comprises substrate 21 and is installed in a plurality of light-emitting components 22 of this substrate 21 and consists of light-emitting device.Substrate 21 is to have the circular-arc of Rack size and with the polylith of shape, 4 block unit substrate 21a specifically, the mode that engages with the Rotational Symmetries of 90 degree sets, thereby forms on the whole roughly round shape.Namely, the substrate 21 that forms on the whole roughly round shape is made up fan shape roughly and the unit substrate 21a that is divided into the same shape of polylith and is consisted of.

Because using the unit substrate 21a of cutting apart as described, thereby utilize mutual seam (cutting part) D among the unit substrate 21a to absorb thermal contraction, thereby can suppress the distortion of substrate 21.And, can obtain efficiently the material of substrate component, thus favourable for cost, and process because of the member miniaturization and to become easy.

Substrate 21 comprises the flat board of the glass epoxy resin (FR-4) as insulating materials, and is forming Wiring pattern in face side by Copper Foil.Light-emitting component 22 and this Wiring pattern electrical connection.And, on Wiring pattern, namely on the surface of substrate 21, apply the white resist layer that plays a role as the reflecting layer.

In addition, the material of substrate 21 can use ceramic material or synthetic resin material in the situation as insulating materials.In addition, being in the metal situation, can use metal basal substrate, this metal basal substrate is that a lamination insulating barrier at the substrate plate that thermal conductivity is good and thermal diffusivity is excellent of aluminium etc. forms.

Light-emitting component 22 is LED, and is the LED packaging body of surface installing type.This LED packaging body is striden and multiple row and being installed with along the Zhou Fangxiang of the substrate 21 of a plurality of round shapes, strides and 3 row and being installed with at the different roughly concentrically ringed circumference of the radius centered by the substantial middle section of substrate 21 in the present embodiment.Namely, stride and the row of the row of interior all sides, outer circumferential side and in these centre of the row of the row of all sides and outer circumferential side row and be installed with.

The LED packaging body comprises haply: be provided in the led chip of the die cavity (cavity) that is formed by pottery or synthetic resin, and the epoxy that this led chip is sealed is the mould translucent resin of resin or silicone resin etc.

With regard to the LED packaging body of the row of the row that are installed in interior all sides and outer circumferential side, what use is that illuminant colour is the LED packaging body of bulb look (LI) and white (W), they roughly separate uniformly-spaced and alternately sequentially on circumference and set, and for example the LED packaging body of bulb look (LI) are arranged in the clockwise direction successively and are set with the LED packaging body of white (W).Specifically, in unit substrate 21a, row in interior all sides are installed with the LED packaging body that 10 illuminant colours are bulb look (LI), 10 illuminant colours are the LED packaging body of white (W), namely add up to 20 LED packaging bodies, row at outer circumferential side are installed with the LED packaging body that 14 illuminant colours are bulb look (LI), 14 illuminant colours are the LED packaging body of white (W), that is, add up to 28 LED packaging bodies.

Led chip is the led chip that sends blue light.Sneaked into fluorophor in the translucent resin, in order to go out the light of white color system of lamp bulb look (LI), white (W), radiated and the yellow fluorophor of the light that blue light as the yellow of complementary color relation is and mainly uses.

With regard to the LED packaging body of the row in the middle of being installed in, use be the LED packaging body that sends the light of redness (R), green (G), blue (B).Therefore, led chip is respectively the led chip that sends redness, green, blue light, and these led chips utilize the translucent resin that mould uses and seal.

These send the LED packaging body of the light of redness (R), green (G), blue (B), on circumference, repeat with certain sequence alternate ground of red (R), green (G), blue (B) successively and roughly separate uniformly-spaced, and for example arrange in the clockwise direction and dispose according to the order of red (R), green (G), blueness (B).Specifically, in unit substrate 21a, the LED packaging body that 12 illuminant colours are red (R), 12 illuminant colours are installed for the LED packaging body of green (G), 12 illuminant colours are the LED packaging body of blueness (B), namely add up to 36 LED packaging bodies.

In addition, the arrangement of the redness in the LED packaging body (R), green (G), blue (B) is not particularly limited as long as be certain order, for example can be according to green (G), red (R), blueness (B) arranged sequentially.

On the different roughly concentrically ringed circumference of radius as described, arow is setting a plurality of light-emitting components 22 of the light that sends bulb look (LI), white (W), on the circumference of the roughly the same circle of center and described circle, and between the row of light-emitting component 22 of the described light that sends bulb look (LI), white (W), arow is setting a plurality of light-emitting components 22 of the light that sends redness (R), green (G), blue (B).

Therefore, owing to setting a plurality of light-emitting components 22 of different illuminant colours, namely, setting the light-emitting component 22 of the light that sends bulb look (LI), white (W), red (R), green (G), blue (B), thereby by making these mixed lights expressible photochromic scope is wide, and can suitably adjust photochromic by the output of adjusting light-emitting component 22.

As described above at the row of interior all sides of unit substrate 21a, middle row and the row of outer circumferential side, the light-emitting component 22 that same number is installed every of the same colour in the multiple illuminant colour.And, the light-emitting component 22 of adjacency take the seam D of unit substrate 21a as the border adjacency, among the unit substrate 21a, what install is the light-emitting component 22 of different illuminant colour, and the partition distance S2 between the mutual light-emitting component of the adjacency in the partition distance S1 of 22 of these mutual light-emitting components and the unit substrate equates.

Namely, the light-emitting component 22 of adjacency take the seam D of unit substrate 21a as the border adjacency, among the unit substrate 21a, that bulb look (LI), white (W) or red (R), green (G), blue (B) are alternately arranged sequentially, the result, at the row of interior all sides and the row of outer circumferential side, as the light-emitting component 22 of different illuminant colours, the luminous light-emitting component 22 of the luminous light-emitting component of bulb look (LI) 22 and white (W) is adjacent.And, the row in the centre, the luminous light-emitting component 22 of blue (B) luminous light-emitting component 22 and red (R) is adjacent.

Therefore, with regard to the unit substrate 21a that consists of as described, even if arbitrary unit substrate 21a is made up, the light-emitting component 22 of the adjacency in take seam D as the unit substrate 21a of border adjacency disposes the light-emitting component 22 of different illuminant colours.Therefore, in the part of the seam D of unit substrate 21a, can avoid light to look nature, and can guarantee light-emitting area homogeneity on the whole.

If in the light-emitting component 22 that is installed in unit substrate 21a, be configured in the situation of redness (R), green (G), blue (B), red (R), green (G), blue (B), red (R), the light-emitting component 22 of the adjacency in take seam D as the unit substrate 21a of border adjacency, that the light-emitting component that red (R) and red (R) is mutually homochromy repeats and adjacency and arranging, the color of light produces factitious part, thereby is difficult to guarantee light-emitting area homogeneity on the whole.

With reference to Fig. 8 and Fig. 9 described situation is specifically described.With light source portion 2, namely substrate 21 is simplified with the light-emitting component 22 that is installed in this substrate 21 and is schematically shown in explanation for Fig. 8 and Fig. 9.

Among Fig. 8, form on the whole roughly the substrate 21 of round shape, fan shape roughly and the unit substrate 21a that is divided into a plurality of same shapes are made up and consist of.And, on the circumference centered by the substantial middle section of substrate 21, alternately and equally spaced with the light-emitting component of multiple illuminant colour, namely red (R), green (G), blue (B) luminous light-emitting component 22 are arranged and be installed with sequentially.

Herein, be made as k at the number with unit substrate 21a, distance till from the center O of substrate 21 to light-emitting component 22 is made as r, the distance of seam D between unit substrate 21a is made as c, the luminous chromatic number of light-emitting component 22 is made as m, the number of the light-emitting component 22 every of the same colour in the multiple illuminant colour is made as in the situation of n, has following relation: the light-emitting component 22 every of the same colour in multiple illuminant colour is installed with n/k (n/k is integer) on unit substrate 21a.

And, j look (j=1～m on take the light-emitting component 22 of the end that is installed in unit substrate 21a as the starting point circumference, order in the luminous chromatic number of arranging sequentially) and with the i in the illuminant colour (i=1～n/k, order in the identical illuminant colour) light-emitting component 22, if the distance on the circumference that will begin to count from the end of unit substrate 21a is made as L, then distance L can be calculated according to following formula 1.

[numerical expression 1]

$L=\frac{1}{2}(\frac{2\mathrm{\πr}}{\mathrm{nm}}-C)+\frac{2\mathrm{\πr}}{\mathrm{nm}}\×\{m\×(i-1)+j-1\}$ (formula 1)

According to this formula 1, be designed at unit substrate 21a configuration light-emitting component 22, and this unit substrate 21a is made up, thus, the light-emitting component 22 of the adjacency in take the seam D of unit substrate 21a as the unit substrate 21a of border adjacency, dispose the light-emitting component 22 of different colors, and the partition distance S1 of 22 of these mutual light-emitting components can with unit substrate in the mutual light-emitting component of adjacency between partition distance S2 equate.

Therefore, in the part of the seam D of unit substrate 21a, can avoid light to look nature, and can guarantee light-emitting area homogeneity on the whole.

Then, according to this formula 1, attempt the luminous light-emitting component 22B of blueness (B) of the right part among for example upper left unit substrate 21a shown in Figure 8 is calculated distance L.Number every of the same colour in unit substrate 21 a is 2, and several k of unit substrate 21a are 4, and therefore the number n of the light-emitting component 22 every of the same colour in the multiple illuminant colour is 2 * 4=8.Because arranging red coloration (R), green (G), blue 3 luminous look light-emitting components 22 of (B), so the luminous chromatic number m of light-emitting component 22 is 3.

And with regard to regard to i in the illuminant colour, among blue (B) luminous light-emitting component 22B, if take the light-emitting component 22 of the end that is installed in unit substrate 21a as starting point, then blue (B) is the 2nd, so i is 2.With regard to the j look, be arranged in that blue (B) is the 3rd look in the light-emitting component 22 of redness (R), green (G), blue (B), thereby j is 3.

Therefore, can as following, calculate distance L to blue (B) luminous light-emitting component 22B, thus but specified configuration.

Can be as calculating the distance L of each light-emitting component 22 as above-mentioned, thus but specified configuration.

Attach and say that in the formula 1,2 π r/nm represent partition distance S1, the S2 of each light-emitting component 22.And, the 1st 1/2((2 π r/nm)-c) expression till from the end of unit substrate 21a to initial light-emitting component 22 apart from a.Therefore, the 2nd (2 π r/nm) * (m * (i-1)+j-1) represent remaining distance b, this is apart from the position of the distance L on circumference a and distance b and that become specific light-emitting component 22.

Then, among Fig. 9, with form shown in Figure 4 similarly, at the row of interior all sides and the row of outer circumferential side, using illuminant colour is the light-emitting component 22 of bulb look (LI) and white (W), they is roughly separated uniformly-spaced and alternately sequentially set on circumference.And, the row in the centre, the light-emitting component 22 of the light of redness (R), green (G), blue (B) is sent in use, they is roughly separated uniformly-spaced and alternately sequentially set on circumference.

For example to begin to count from the end of the row of the outer circumferential side of upper left unit substrate 21a be the 6th light-emitting component 22W to shown in Figure 9 in trial, calculates distance L.Because the number every of the same colour among the unit substrate 21a is 4, several k of unit substrate 21a are 4, so the number n of the light-emitting component 22 every of the same colour in the multiple illuminant colour is 4 * 4=16.Because arranging bulb look (LI), white 2 luminous look light-emitting components 22 of (W), so the luminous chromatic number m of light-emitting component 22 is 2.

And, with regard to individual with the i in the illuminant colour, because white (W) is the 3rd, so i is 3.With regard to the j look, because the white (W) in the light-emitting component 22 that is arranged in bulb look (LI), white (W) is the 2nd look, so j is 2.

Therefore, can as following, calculate distance L to white (W) luminous light-emitting component 22W, thus but specified configuration.
