 Below, use figure 1 The first embodiment of the present invention will be described in detail. figure 1 It is explanatory drawing of the light emission state of LED101 in 1st Embodiment of this invention.
 Such as figure 1 As described in (a), LED101 emits light from the light emitting surface 101a.
 Here, LED101 is an example of a light emitting element, and other light emitting elements can also be used similarly.
 In addition, θ is an angle formed with the normal direction of the light emitting surface 101a.
 The LED 101 emits light for every angle θ.
 figure 1 (b) and figure 1 (c) is a light quantity distribution diagram of LED101 at angle (theta).
 figure 1 (b) is an example of LED101 (cos type) whose light intensity is the strongest when θ is 0°, figure 1 (c) is an example of LED 101 (ring type) where light intensity is strongest when θ is around 30°.
 However, some manufacturing errors exist when m...
