[annexation of LED module and pillar and lead-in wire]
Then, utilize Fig. 6 to describe LED module 20 and the annexation of pillar 40 and lead-in wire 70.Fig. 6 shows the formation of the LED module periphery in the related bulb-shaped lamp of present embodiment 1.And, (a) of Fig. 6 is the state to remove enclosed globe shade 10 in bulb-shaped lamp 1, plane during from top LED module 20, (b) of Fig. 6 is the profile of this bulb-shaped lamp 1 on the X-X ' line of (a), and (c) of Fig. 4 is the profile of this bulb-shaped lamp 1 on the Y-Y ' line of (a).

[action effect]
Then, utilize Fig. 7 to describe the action effect of the related LED module 20 of present embodiment.Fig. 7 is the figure of the action effect of the LED module 20 for the related bulb-shaped lamp 1 of embodiment 1 of the present utility model is described, (a) be a part of amplification profile of the LED module 200 of comparative example 1, (b) being a part of amplification profile of the LED module 201 of comparative example 2, is (c) a part of amplification profile of the LED module 20 in embodiment 1.
As shown in Fig. 7 (a), the formation of the LED module 200 of comparative example 1 is, the first seal member 23a (containing fluorophor resin) of sealing LED 22a is adjacent with the second seal member 23b (containing fluorophor resin) of sealing LED 22b, as shown in the embodiment, do not form the first illusory seal member 24a.
In the LED module 200 of comparative example 1, if the area of substrate 21 increases, the interval of the first seal member 23a and the second seal member 23b becomes large.Consequently, the region (non-illuminating part) that does not form the first seal member 23a and the second seal member 23b increases, thereby cause in substrate 21, form the region (illuminating part) of the first seal member 23a and the second seal member 23b and do not form that between the region (non-illuminating part) of the first seal member 23a and the second seal member 23b, obvious light and shade to occur poor, thereby occur brightness irregularities.
Therefore, shown in the related LED module 201 of comparative example 2 as shown in Fig. 7 (b), the formation that can consider is to carry out all LED (LED22a and LED22b) on covered substrate 21 with seal member 23A (containing fluorophor resin).For example, the mode that becomes rectangle with the flat shape of seal member 23A forms seal member 23A.
But, in this formation, owing to becoming plane above seal member 23A, will inject to outside light (light being sent by LED22a, 22b and the light sending from the fluorophor particle) ratio that (interface of seal member 23A and air layer) reflected on seal member 23A increases from the inside of seal member 23A.Like this, the ratio that injects to outside light from the inside of seal member 23A will reduce, thereby causes light to take out Efficiency Decreasing.Therefore,, in the LED module with this formation, can not realize high beam.
To this, LED module 20 in present embodiment shown in Fig. 7 (c) is, between the first seal member 23a (the first ML1 of main light emission portion) and the second seal member 23b (the second ML2 of main light emission portion), the first illusory seal member 24a (the first secondary illuminating part SL1) is set.
Accordingly, the light that LED22a from the first ML1 of main light emission portion penetrates, can be encouraged by the fluorophor particle of the first seal member 23a (the first wavelength transform component WC1) that covers self, and also can be by the fluorophor particle excitation of the first illusory seal member 24a (second wave length transform component WC2) adjacent with the first seal member 23a.Equally, the light that LED22b from the second ML2 of main light emission portion penetrates, can be encouraged by the fluorophor particle of the second seal member 23b (three-wavelength transform component WC3) that covers self, and also can be by the fluorophor particle excitation of the first illusory seal member 24a (second wave length transform component WC2) adjacent with the second seal member 23b.
In the present embodiment, LED22a and 22b are the blue led chip that sends blue light, and the fluorophor particle (wavelength shifter) in the first seal member 23a, the second seal member 23b and the first illusory seal member 24a is yellow fluorophor particle.Therefore, the blue light sending from the first ML1 of main light emission portion (the first seal member 23a), the second ML2 of main light emission portion (the second seal member 23b) and the first secondary illuminating part SL1 (the first illusory seal member 24a), by the sodium yellow after yellow fluorophor particle wavelength conversion with do not mixed by the blue light of yellow fluorophor particle wavelength conversion, thereby emit the white light as mixed light.
Like this, not only can be luminous by LED module 20, the first seal member 23a and the second seal member 23b in present embodiment, and also the first illusory seal member 24a also can be luminous., the first illusory seal member 24a can be played a role as doubtful illuminating part.Consequently, because the first seal member 23a, the second seal member 23b and the first illusory seal member 24a can play a role as illuminating part, therefore, for the formation of Fig. 7 (a), light and shade in substrate 21 can be suppressed poor, and brightness irregularities can be suppressed.
And, in LED module 20 in the present embodiment shown in (c) of Fig. 7, article three, each section shape of seal member (containing fluorophor resin) is dome-type section (being almost semicircle), therefore in the ejaculation light from seal member to outside, can suppress total reflection at the interface of seal member and air layer.Therefore,, in the LED module 20 of present embodiment, there will not be the light shown in (b) of Fig. 7 to take out the reduction of efficiency.
And, in bulb-shaped lamp 1 in the present embodiment, owing to having adopted the LED module 20 shown in (c) of Fig. 7 as light source, therefore, can realize the few bulb-shaped lamp of brightness irregularities in light source.
And, in LED module 20 in the present embodiment, concentration by the fluorophor particle (three-wavelength coversion material) in concentration and/or the second seal member 23b of the fluorophor particle (the first wavelength shifter) in concentration and the first seal member 23a of the fluorophor particle (second wave length coversion material) in the first illusory seal member 24a is adjusted, thereby can carry out color adjustment.In this case, preferably below the concentration of the fluorophor particle of the concentration of the fluorophor particle in the first illusory seal member 24a in the first seal member 23a and the second seal member 23b.Below, this point is described.
In the first seal member 23a, the second seal member 23b and the first illusory seal member 24a, if the concentration of the fluorophor particle in each seal member is identical, be formed on the first seal member 23a of both sides of the first central illusory seal member 24a and the light that the second seal member 23b both sides' LED emits and can incide this first illusory seal member 24a, the white light jaundice (yellow compared with the light of Strong) that the white light of emitting from the first illusory seal member 24a like this, can be emitted than the first seal member 23a and the second seal member 23b.Like this, between the first illusory seal member 24a and the first seal member 23a and the second seal member 23b, can there is the inhomogeneous of color.
Therefore, by making the concentration of the fluorophor particle in concentration ratio the first seal member 23a and the second seal member 23b of the fluorophor particle in the first illusory seal member 24a little, thereby can make the wavelength conversion efficiency in the first illusory seal member 24a less than the wavelength conversion efficiency in the first seal member 23a and the second seal member 23b.Accordingly, can be suppressed at the first illusory seal member 24a and generate sodium yellow, thereby can make light that the first illusory seal member 24a emits closer to white.Like this, can suppress the irregular colour one between the first illusory seal member 24a and the first seal member 23a and the second seal member 23b.
For example, the concentration of the fluorophor particle in the first illusory seal member 24a can be set as the fluorophor particle in the first seal member 23a and the second seal member 23b concentration 15% to 40%.
And, for the inhibition (color adjustment) of the irregular colour one in the first seal member 23a, the second seal member 23b and the first illusory seal member 24a, also the concentration of the fluorophor particle to each seal member is not adjusted, but the height of each seal member is adjusted.For example, the concentration of the fluorophor particle in the first seal member 23a, the second seal member 23b and the first illusory seal member 24a is made as identical, be lower than the height of the first seal member 23a and the second seal member 23b by the height setting of the first illusory seal member 24a, can make like this wavelength conversion Efficiency Decreasing of the first illusory seal member 24a.Accordingly, can be suppressed at the first illusory seal member 24a and generate sodium yellow.Consequently, can suppress the irregular colour one between the first illusory seal member 24a and the first seal member 23a and the second seal member 23b.
Or, length by each seal member to the first seal member 23a, the second seal member 23b and the first illusory seal member 24a is adjusted, and also can carry out the color adjustment (inhibition of irregular colour one) in the first seal member 23a, the second seal member 23b and the first illusory seal member 24a.For example, the concentration of the fluorophor particle in the first seal member 23a, the second seal member 23b and the first illusory seal member 24a is made as identical, by the length setting of the first illusory seal member 24a below the length of the first seal member 23a and the second seal member 23b, the irregular colour one between such first illusory seal member 24a と the first seal member 23a and the second seal member 23b.
And, in Fig. 7 (c), although the first ML1 of main light emission portion (the first seal member 23a), the second ML2 of main light emission portion (the second seal member 23b) and the first secondary illuminating part SL1 (the first illusory seal member 24a) are illustrated, the 3rd ML3 of main light emission portion (the 3rd seal member 23c), the 4th ML4 of main light emission portion (the 4th seal member 23d) and the second secondary illuminating part SL2 (the second illusory seal member 24b) are also same.
And, in the present embodiment, to existing the first secondary illuminating part SL1 (the first illusory seal member 24a) to be illustrated between the first ML1 of main light emission portion (the first seal member 23a) and the second ML2 of main light emission portion (the second seal member 23b), but, only in the case of existing, the one party of the first ML1 of main light emission portion (the first seal member 23a) and the second ML2 of main light emission portion (the second seal member 23b) and the first secondary illuminating part SL1 (the first illusory seal member 24a) also can be suitable for., also can be applicable to be only a main light emission portion and a situation that secondary illuminating part is adjacent to the utility model.Like this, by making secondary illuminating part adjacent with main light emission portion, thereby it is poor to suppress light and shade on substrate.
