Simulative eye for toy

Abstract

A simulative eye is capable of being operated between a normal state and a dilated state. The simulative eye includes an eyeball, a pupil disposed on the eyeball, an iris surrounding the pupil, and a light source. When the simulative eye is in a normal state, a color of the iris is different from that of the pupil when the iris is not irradiated by the light emitted from the light source. When the iris is irradiated by the light emitted from the light source, the color of the iris is almost the same as that of the pupil. As a result, the simulative eye is changed from the normal state to the dilated state.

1 . A simulative eye, comprising:
 an eyeball comprising a pupil and an iris surrounding the pupil; and   a light source configured to emit light;   wherein a color of the iris is different from that of the pupil when the iris is not irradiated by the light emitted from the light source; and   the color of the iris is substantially the same as that of the pupil when the iris is irradiated by the light emitted from the light source.   
   
   
       2 . The simulative eye in  claim 1 , wherein the simulative eye further comprises a shell for receiving the eyeball, an opening is defined in the shell, the pupil and the iris are exposed at the opening. 
   
   
       3 . The simulative eye in  claim 2 , wherein the simulative eye further comprises a supporting plate received in the shell, the light source is mounted on the side of the supporting plate facing the pupil. 
   
   
       4 . The simulative eye in  claim 1 , wherein the simulative eye further comprises a shielding member mounted in the eyeball and made of a lightproof material, a hole is defined in the shielding member, and is arranged for allowing the light emitted from the light source to be transmitted therethrough to arrive at the pupil and the iris. 
   
   
       5 . The simulative eye as described in  claim 4 , wherein the diameter of the hole is larger than that of the pupil. 
   
   
       6 . The simulative eye as described in  claim 3 , wherein the pupil and the iris are disposed in the eyeball via in-mold-decoration (IMD). 
   
   
       7 . The simulative eye as described in  claim 1 , wherein the color of the pupil is black. 
   
   
       8 . The simulative eye as described in  claim 7 , wherein the color of the iris is blue, and the light source emits red light. 
   
   
       9 . A simulative eye capable of being operated between a normal state and a dilated state, the simulative eye comprising:
 a shell defining an opening;   an eyeball received in the shell, the eyeball formed with a first portion for simulating a human's pupil and a second portion surrounding the first portion for simulating a human's iris, the pupil exposed at the opening with a first color in the normal state, the iris exposed at the opening with a second color in the normal state; and   a light source received in the shell, the light source capable of emitting a first light beam for irradiating the second portion;   wherein when the light source is operated to emit the first light beam to irradiate the second portion, the iris is exposed at the opening with the first color for increasing an area of the pupil with the first color so as to change the simulative eye from the normal state to the dilated state.   
   
   
       10 . The simulative eye in  claim 9 , wherein an intensity of the first light beam is gradually increased. 
   
   
       11 . The simulative eye in  claim 9 , wherein the light source is capable of stop emitting light beam to the second portion, the area of the pupil with the first color is decreased to change the simulative eye from the dilated state to the normal state. 
   
   
       12 . The simulative eye in  claim 9 , wherein the light source is capable of emitting a second light beam for irradiating the second portion, the area of the pupil with the first color is decreased to change the simulative eye from the dilated state to the normal state. 
   
   
       13 . The simulative eye as described in  claim 12 , wherein an intensity of the second light beam is gradually increased.
