Embodiment 4 similarly to Example 1, the shape that peristome is installed in the cover 1 of the part sphere on the cover installation portion 4 of main part 2 is envisioned for sphere, as shown in Figure 5, LED6 is configured in from covering on 1 the sphere towards the center of this cover 1 roughly on the position of 1/4 distance.That is, this LED6 is arranged on roughly 3/4 the position of cover 1 radius and in peristome one side of this cover 1.
In embodiment 5, same with embodiment 1 and 4, the shape that peristome is installed in the cover 1 of the part sphere on the cover installation portion 4 of main part 2 is envisioned for sphere, as shown in Figure 6, with LED6 be set in place on the sphere of cover 1 with the center of this cover 1 roughly on the position of centre.That is, this LED6 is arranged on roughly 1/2 the position of cover 1 radius and in peristome one side of this cover 1.
In embodiment 6, same with embodiment 1,4 and 5, the shape that peristome is installed in the cover 1 of the part sphere on the cover installation portion 4 of main part 2 is envisioned for sphere, as shown in Figure 7, LED6 is configured in from covering on 1 the sphere towards the center of this cover 1 roughly on the position of 3/4 distance.That is, this LED6 is arranged on roughly 1/4 the position of cover 1 radius and in peristome one side of this cover 1.
Embodiment 7 and embodiment 1,4 to 6 are same, and the shape that peristome is installed in the cover 1 of the part sphere on the cover installation portion 4 of main part 2 is envisioned for sphere, as shown in Figure 8, LED6 is arranged on the center of spherical cover 1.
Embodiment 8 and embodiment 1,4 to 7 are same, the shape that peristome is installed in the cover 1 of the part sphere on the cover installation portion 4 of main part 2 is envisioned for sphere, as shown in Figure 9, LED6 is configured in from covering on 1 the sphere towards the center of this cover 1 roughly on the position of 3/4 distance and in a side opposite with peristome.That is, this LED6 is arranged on roughly 1/4 the position of cover 1 radius and in a side opposite with the peristome of this cover 1.
Embodiment 9 and embodiment 1,4 to 8 are same, the shape that peristome is installed in the cover 1 of the part sphere on the cover installation portion 4 of main part 2 is envisioned for sphere, as shown in figure 10, LED6 is configured on the position that is positioned on cover 1 the sphere with the centre, center of this cover 1 and in a side opposite with peristome.That is, this LED6 is arranged on roughly 1/2 the position of cover 1 radius and in a side opposite with the peristome of this cover 1.
Embodiment 10 and embodiment 1,4 to 9 are same, the shape that peristome is installed in the cover 1 of the part sphere on the cover installation portion 4 of main part 2 is envisioned for sphere, as shown in figure 11, LED6 is configured in from covering on 1 the sphere towards the center of this cover 1 roughly on the position of 1/4 distance and in a side opposite with peristome.That is, this LED6 is arranged on roughly 3/4 the position of cover 1 radius and in a side opposite with the peristome of this cover 1.
According to above such cover 1 shape with part the spherical and oval sphere of a part and different embodiment 1～3, as shown in Figure 2, be envisioned for sphere and LED6 be configured under the situation of the embodiment 1 on the sphere that has made spherical cover 1 the luminous intensity distribution distribution that the formation balance is the best in the shape that will cover 1.That is, embodiment 1 and embodiment 2,3 compare, and utilize the angle of cover 1 diffusion function that has and inclination, LED incident light, form the luminous intensity distribution distribution that irradiation also arrives the back portion of LED6.
On the other hand, cover 1 be shaped as oval ball (with directly over be 2 times of minor axis to the major diameter of the side of identical direction) embodiment 2 in, as shown in Figure 3, from the directive property of LED6 than the light of 60 ° of big angles all in cover 1 place total reflection, along directly over upwards advance.This result from directive property than the light of 60 ° of big angles for the incidence angle of cover 1 all more than or equal to 42 °.That is,,, in embodiment 2, can not reach the luminous intensity distribution distribution of wide region owing to carry out total reflection with light more than or equal to 42 ° angle incident for cover 1 because of the relation of following [formula 1].
[formula 1]
If the refractive index of air is 1, the refractive index of glass is 1.5, and critical angle (causing the incidence angle of total reflection) is θ
0, then
Sin θ
0The refractive index of the refractive index/glass of=air=0.67
In addition, the sphere that is shaped as according to cover 1 is common and embodiment 1,4 to 10 that position LED6 has nothing in common with each other, as shown in Figure 6, LED6 be set in place on cover 1 the sphere with the position in the middle of roughly, the center of this cover 1 on the situation of embodiment 5 under, form the best luminous intensity distribution distribution of balance that illumination is mapped to the back portion of LED6.
In fact, in embodiment 5 since as shown in Figure 6 light for cover 1 incidence angle all smaller or equal to 42 °, so do not cause total reflection.Therefore, light is not focused on the part, can suppress the hot spot of working flare.In addition, arrive cover 1 o'clock, owing to produce the such diffusion of Figure 13, so can realize the luminous intensity distribution distribution represented among the such Figure 12 of wraparound more for the back side of LED6 at light.That is, obtain the luminous intensity distribution distribution of the light distribution characteristic that approaches the such incandescent lamp of Figure 15.
At this, even the situation of embodiment 4 and 7, though not resembling the embodiment 5 illumination is mapped to the back portion of LED6 and forms the good light of balance and distribute, but it is luminous equably that the diffusion that can utilize light makes it, in addition, though how much cause total reflection,, can realize the light distribution characteristic of the back portion of light arrival LED6 to a certain degree owing in cover 1, produce diffuse reflection.
On the other hand, in embodiment 1, as shown in Figure 2, because light carries out total reflection at cover 1 place near directive property is 120 °, so if with embodiment 4 relatively, lack towards the luminous intensity distribution of the back portion of LED6, can not obtain that such luminous intensity distribution of expression distributes among Fig. 5 to 7.
In addition, 1 place, center at cover is provided with among the embodiment 7 of LED6, since for cover 1 incidence angle smaller or equal to 42 °, so light does not carry out total reflection and directly advances, and then since light for the cover 1 incident generally perpendicularly, so light, can not obtain the good luminous intensity distribution of balance and distribute with roughly original angle reflection towards light source.Even in embodiment 8, according to same reason, more smaller or equal to 42 ° light for cover 1 incidence angle, light does not carry out total reflection and directly advances, so since light for cover 1 incident generally perpendicularly, so can not obtain the good luminous intensity distribution distribution of balance.
In embodiment 9 and 10, because too approach on the sphere of an opposite side with peristome at the position that is provided with of LED6, so, can not obtain the luminous intensity distribution distribution in the wide scope according to the intensity of the directive property of this LED6, in addition, the light quantity towards back portion that can not say LED6 is sufficient.
[3. summing up]
According to checking result as described above, as shown in Fig. 5 to 7, as can be known, be that spherical, LED6 is configured in from covering on 1 the sphere towards the center of this cover 1 roughly on the position of 1/4～3/4 distance and being to obtain suitable structure aspect the luminous intensity distribution distribution character of wide region at the embodiment 4 to 6 of peristome one side in cover 1 shape.Particularly, light smaller or equal to 42 ° does not cause all that for cover 1 incidence angle total reflection, the embodiment 5 that also produces the diffusion of light fully in addition can be described as the structure of the best when the luminous intensity distribution of realizing the wide region that incandescent lamp is such distributes.
Like this, utilize to realize wide region luminous intensity distribution cover 1 shape and LED6 be provided with in the position by with the combination of the diffusion function of the light of cover 1, as embodiment 4 to 6, can have wideer light in the back side of LED6 one side and distribute.
In addition, in view of because of can not obtaining sufficient luminous intensity distribution distribution this point towards the incidence angle of the light of cover 1 and the directive property of LED6 among the embodiment 1 in cover light quantity of 1 place total reflection and embodiment 7 to 10, the position that is provided with of LED6 is to see that from covering 1 center it is being more satisfactory aspect the light distribution characteristic that peristome one side be we can say as embodiment 4 to 6.Promptly, if see in peristome one side LED6 be set from covering 1 center, though then can not deny producing some total reflections according to the situation that the position is set, be inadequate towards the light quantity of the back portion of this LED6, can realize that the luminous intensity distribution that reaches wide region to a certain degree distributes.
According to such result, we can say that diffuse reflection takes place most in realization but minimum and then produce the shape of cover 1 of state of diffusion of the light that reaches wide region and the position that is provided with of LED6 is best structure at cover 1 inner full-reflection.
[other embodiment]
In addition, the present invention is not limited to embodiment as described above, also comprise following embodiment: the light at LED6 incides under the situation that also will be decided to be 90 ° on the cover 1 in the angle that the outer surface that covers 1 pass, because cover 1 is passed at the refraction angle when keeping this light incident, so obtain luminous intensity distribution arbitrarily by the thickness that utilizes this principle partly to adjust the part of cover 1.
