     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring to FIGS. 1 to 11, a key light holder 10 for key organization according to a preferred embodiment of the present invention is illustrated. 
     The key light holder comprises a holder 10, a key organizer device 20 and a light device 30. The holder 10 comprises a front panel 11 connected with a back panel 12 to define a receiving chamber 13 therein, as shown in FIG. 6. 
     The key organizer device 20 is affixed in the holder 10 and comprises a thread 21 having a first end 22 capable of being extended from the holder 10 for organizing keys 40 when a pulling force is applied to the first end of the thread 21, and a self retractable thread device 23 for retracting the thread 21 back into the holder 10 when the pulling force is released. 
     The front panel 11 and the back panel 12 are shaped by Pneumatic Press from thin metal, such as brass, stainless steel or flexible steel, to form a holder. These metals are found available in local steel suppler. These thin metals can be cut, bent and punched to form a shape. A small light device 30 and the key organizer device 20 are affixed inside the holder 10. 
     The front panel 11 is a made of a thin 0.76 mm brass sheet which is press but to a shape as shown in FIG. 4. Then, it is pressed to form a container shape having a deep of 5 mm for covering the light device 30 and the key organizer device 20, as shown in FIG. 4A. Two holes 111, 112 are formed in the middle on two sides which are respectively functioned as a light window and for positioning a switch button 31. A pin 14 is inserted between two small holes 113, 114 in the bottom on two sides to connect the back panel 12. 
     The back panel 12 is made of a thin 0.3 mm stainless steel sheet which is press cut a shape as shown in FIG. 5. Then, it is bent to form two connecting parts in two sides of the bottom thereof, as shown in FIG. 5A. The back panel 12 has seven holes form thereon by means of a punch processing, wherein a first hole 121 positioned at top of the back panel 12 is adapted to hang the complete holder 10 on to a key chain 41, two holes 122, 123 formed in the middle are for holding the light device 30, two holes in the bottom 124, 125 are for fixing the key organizer device 20, and two little holes 126, 127 on the connecting part 12a, 12b are for connecting the pin 14. A small square space 128 is cut out by press and a small half round shape 129 is formed near the bottom. The small square space 128 is for the thread 21 in and out. The half round shape 129 is a hand for a ring 231 of the self-retractable thread device 23, which is affixed at the first end 22 of the thread 21, to hand on to form a lock. 
     As shown in Figures. 6 and 6A, the pin 14 is inserted through the two small holes 113, 114 in a bottom on two sides of the front panel 11 and the two little holes 126, 127 provided on the two connecting part 12a, 12b of the back panel 12 so as to pivotally connect the front panel 11 and the back panel 12 together. 
     The key organizer device 20 of the present invention has an improvement from a prior application, where two arms have been substituted by the self retractable thread device 23. 
     As shown in FIGS. 8 to 8E, the self retractable thread device 23 comprises the ring 231, a wheel 232, an axle 233, and a basis element 234. The wheel 232 is made out by metal that has a thickness of 2 mm and a diameter of 10 mm. The wheel 232 has wheel 232 has a circle hole 232a positioned in a middle and two holes 232b located close to its circle and one hole. The thread 21 is made of durable material such as nylon and preferred have a length of 80 mm and a diameter of 1 mm. The thread 21 has a second end 211 tied on the circle hole 232a of the wheel 232 while the first end 22 tied to the ring 231, as shown in FIG. 8A. The thread 21 is coiled on the wheel 232 from the first end 211 and is capable of extending out by pulling out the ring 231 to form a lock for organizing keys 40, as shown in FIG. 8B. 
     The ring 231, which has a diameter of 5 mm, is made of flexible metal. The ring 231 ties the thread 21 together, as shown in FIG. 8A. Pulling out the ring 231 will bring the thread 21 out. Handing the ring 231 on the hand will form a lock to organize the keys 40. 
     The key organizer device 20 further comprises a retractable unit 24 installed between the basis element 234 and the wheel 232 for enabling the wheel 232 to move on the axle 233 by pulling the ring 231 out and retracting the thread 21 when releasing the ring 231. 
     The retractable unit 24 is a coil spring which has a center end tied on a center of the basis element 234 and an other end tied on the circle hole 232a of the wheel 232. The axle 233 is placed through the center hole 232a of the wheel 232 to the basis element 234 so as to tighten the center end of the coil spring 24 onto the basis element 234. Moreover, a cover 235 is used to place over the wheel 232, the coil spring 23 and the basis element 234, which limits the wheel 232 can only move inside the cover space13, as shown in FIG. 8E. 
     The coil spring 24 has a 8 mm diameter and is made of flexible metal. The center end of the coil spring 24 is tied on the center of the basis element 234, as shown in FIG. 8C. Other end of the spring 24 is tied on the circle hole 232a of the wheel, as shown in FIG. 8D. When the wheel 232 rotates, it forces the spring 24 to rotate about the spring center. This force is transferred into the coil spring 24. The coil spring 24 will force the wheel 232 rotating back. The wheel 232 rotating back makes the thread 21 retracting back. 
     The axle 233 is placed through the wheel center hole 232a to the center of the basis element 234. The axle 233 will tighten the spring center end onto the basis element 234 too. The wheel 232 moves on the axle 233 by pulling the ring 231 out and releasing the ring 231. The axle 233 does not move. 
     As shown in FIGS. 7, 7A, 9, and 11, the light device 30 comprises a rubber made switch button 31 affixed on a circuit board 32, at least a 1.5V cell battery to power up at least a LED light 33, and a press switch 34 made by copper wire and operated by the switch button 31, wherein FIG. 7A illustrates the press switch 34 connecting to the circuit board 32 when the LED light 33 on. 
     The complete key light holder is formed by affixing the key organizer device 20 and the light device 30 on the back panel 12, as shown in FIG. 9, and combining the front and back panels 11, 12, as shown in FIG. 6A. 
     The manner of operating the key light holder to organize keys is described below. 
     Put the key light holder into a key chain 41, as shown in FIG. 10. Pull the ring 231 out to tie the keys. Release the ring 231 and let the thread 21 retract back, as shown in FIG. 10A. To locate a key or a lick in dark, press the press button 31 to turn on the LED light 33, as shown in FIG. 11. A logo may be printed on face to decorate the key light holder. 
     In view of above, a number of advantages of the key light holder of the present invention become evident: 
     (a) One Pneumatic Press can do complete the jobs including cutting, punching, pressing, bending, riveting, and marking. 
     (b) A thin 0.76 mm brass and 0.3 mm stainless steel sheets are soft to cut and form. The front and back panels weight a key only. 
     (c) The light device and the key organizer device can be made separately. 
     (d) Assembly of all parts can be done by same Pneumatic Presses. 
     (e) The LED can be in many colors, such as red, yellow, blue, and etc. 
     (f) The key organizer device is in small size, so that it can tie different number key. 
     (g) The metal material has longer use life and environmental friendly. 
     (h) Lower the key noise when organizing the keys. 
     (i) Provide a light source in dark. 
     (j) Face creates area for an image imprint. 
     The present invention has further more advantages in use, such as it can be coated in many colors in face, a phone number can be printed on the back to help recover the key when lost, face area can be used to print logo, and metal can be recycled. 
     Although the description above contains many specificities, these should no be construed as limiting the scope of the invention but merely providing illustrations of the presently preferred embodiments of this invention. For example, the key light holder can have other shape, such as oval, triangular, and etc. Also, the holder can be made of other material, such as plastic and wood, etc.
