     The current invention applies the persistence of vision effect to a desktop or outlet plug-in LED light device to cause LED array light effects to be seen by viewers as light patterns such as a message display, time display, color changing display, word display, logo display, or advertisement display. It also provides a sealed-unit with self-test certification issued by laboratories for add-on shades to provide a more exciting and eye-catching LED device. Each light device has a desired power source, circuitry, switch, sensor, timer and/or other related parts and accessories to cause the light to have a long life and be convenient to people to use. 
     The light device with special effects of the current invention may include one or more of the following 14 features:
     1. The LED light device with special effects may include a special effects mechanism made up of
       at least one LED array arranged on a substrate, and at least one spin means for rotating the substrate means at a predetermined speed (RPM) about an axis extending from the spin means. The predetermined speed is preferably sufficient to provide a persistence of vision effect as described below.   The LED or LEDs of the light device will turn on and off according to a predetermined pattern, timing, color, function, and/or effects and controlled by an appropriate circuit, switch, sensor, timer, auto turn on and turn off, power source (DC, AC, or interchangeable power source), gear sets, motor, integrated circuit (IC), and/or conductive means to cause the light device to exhibit desired light patterns such as a message display, time display, color changing display, word display, logo display, and advertisement display.   The LED light device having persistence of vision properties includes a desktop or outlet plug-in type housing for any substrate, spin means, LED(s) or LED arrays, motor, switch, sensor, circuit, IC, and power source means provided in the light device.   The LED light device may further incorporate a vibration absorbing means to absorb all vibrations of the motor or spin means vibration when people put the device on a desk top or plug-in outlet.   
       2. The LED light device with special effects may include a sealed unit for at least one LED, the sealed unit having its own safety certification issued by a laboratory to meet the applicable safety standard and a receiving means to allow different shades to be added onto the sealed unit to obtain a final LED light device with special effects provided by the shades.
       The added on shades may be made of plastic, paper, wood, a laser piece, a hologram piece, an air-bag, a balloon, assembly pieces, a light block out means, or a grill to cause the final LED light device with special light effects to have an eye-catching appearance. Because all electrical parts are in the already-certified sealed unit, the final LED light device does not need to pass any other laboratory&#39;s further tests. As a result, the shade can be made of any kind of material.   The final LED light device may use any power source, such as a battery, outlet, or power source that is interchangeable between DC and AC power sources for desk top or plug-in application.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     As explained above, the current invention may apply the persistence of vision effect to enable the LED(s) or LED array to form light patterns such as color changing patterns, or a time display. The effect is based on the inertia of the human eye which has a response time of around 1/24 to 1/16 second. Hence, the LED(s) or LED array light can be controlled to change faster than the 1/24 (41.67 msec) to 1/16 (0.0625 sec) second response time so that even though an object moves faster than the human eye response time, the last image stays in the human eye and brain for a period of time. This effect is possible because the LED response time is very short, around 10 msec or less. Hence, if an object appears in front of the human eye for more than 16-24 pictures in a second, people will think all pictures are continuous. Hence, the current invention uses appropriate circuits, control means, an IC, and/or a micro controller to cause the LED or LEDs to blink much faster than 16-24 times (cycles) per second, with each cycle having a 10% turn-on duration and 90% turn-off duration to save up to 90% of the power consumption or increase battery life up to nine times more than would be the case with a full steady-on condition. This is a significant power saving for all battery power source applications. It will further be appreciated that new LED technology may be coming soon which will make the LED have an even quicker response time of less than 10 msec, perhaps 5 msec time or 2 msec to provide even more power saving. To thus adjust the turn-on and turn-off duration time for each cycle will enable more power saving devices to meet the green world concept. 
     To provide further cost saving in the case of a battery-powered unit, the preferred light device can use cheap batteries with a voltage lower than the LED trigger voltage and voltage boosting electric components, parts and accessories to raise the battery&#39;s lower voltage to trigger the LED or LEDs. This can reduce the quantity of batteries required and save substantial cost. 
     The current invention can include any of the 14 features described above, as described below in connection with  FIGS. 1-13 : 
     As shown in  FIGS. 1 to 4 , the first preferred embodiment of the current invention includes a sealed-unit with its own laboratory test certification and a plurality of different add-on shades made by bags which can be filled up with, air, liquid, miniature decorative objects, laser film, hologram film or material piece(s) other than the afore-mentioned decorative objects, laser film, or hologram film. The sealed unit ( 1   a )( 2   a )( 3   a )( 4   a ) of each of  FIGS. 1-4  includes housings having a same front housing part and different rear parts ( 1   b )( 2   b )( 3   b )( 4   b ) which have different lengths from the wall to the sealed-unit to accommodate the top balloon shades ( 1 ) ( 2 ) ( 3 )( 4 ). Each balloon shade has a center channel ( 1   e ) ( 2   e )( 3   f )( 4   e ) into which tubular extensions ( 1   f )( 2   f )( 3   g ) ( 4   f ) of the sealed unit are easily inserted before the balloon is filled up with air, liquid, and/or miniature decorative objects. After the air, liquid, and/or miniature decorative objects are filled into the balloon, the channels will become narrow and tightly hold the tube parts so that they are very difficult to move away. The LED or LEDs inside the tube parts may have a variety of arrangements such as the ones disclosed in the above-cited applications of the inventor. The tube can also be filled up with reflective material, air bubbles, LEDs, glitter, and air to provide the whole shade with a desired light performance. 
       FIGS. 5-1  to  5 - 5  show light devices having sealed units and a variety of different functions.  FIGS. 5-1  shows a sealed unit in the form of an interchangeable power source ( 51   d ) including one LED ( 51   e ) on a base of tube part ( 51   h ), the sealed unit including a manual switch ( 51   i ).  FIGS. 5-2  shows a light device with tube part ( 52   b ), and a sealed unit having a manual switch ( 52   f ) and LEDs ( 52   e ) installed on an elongate printed circuit board ( 52   c ). The light device of  FIGS. 5-3  has a tube part ( 53   b ), auto sensor switch ( 53   f ), and LEDs ( 53   d ) installed on PCB ( 53   c ). The light device of  FIGS. 5-4  has a manual switch ( 54   f ) on the sealed unit and a tube part ( 54   b ) having a plurality of LEDs that face in different directions and are connected to conductive wires to provide multi-directional LED illumination. The light device of  FIGS. 5-5  has motion sensor switch ( 55   f ) on the sealed unit and a tube part ( 55 B) having a plurality of LEDs installed on flexible electric wire cable.

       FIG. 8  shows LEDs ( 8   g ) ( 8   g ′) ( 8   g ″) and LEDs ( 8   h ) ( 8   h ′) ( 8   h ″) installed on a substrate ( 80  assembled with spin means (not shown) inside a base housing ( 8   c ). The substrate is sealed within a transparent ball shaped housing ( 8   a ) to allow people to see the LEDs&#39; light performance for desk top or outlet plug-in applications. The base (not shown) of the light device may be arranged to absorb vibrations when the light device is put on a desktop or plugged-into an outlet. 
       FIG. 9  shows a light device with a soft material substrate ( 9   f ) in a bar shaped design with a dome center area to deliver electricity by conductive means ( 9   d ) and a conductive axis ( 9   b ) of a spin means. The dome center area enables assembly of the bars with respect to the spin mean axis to cause the two bars to rotate when the switch ( 9   j ), sensor, or control means is activated. The plurality of LEDs ( 9   g ) ( 9   h ) ( 9   i ) can be any number to form a message display having a desired color, brightness, time, message, and words for presentation to a viewer. The LED or LEDs connect with a circuit board or micro controller for time display (such as PIC 16F84) having an integrated circuit (IC) that can display the time, message, or words according to conventional market available skill. The spin means (not shown) can be a motor and is sealed within a motor housing ( 9 ) with fastening means assembled with all related parts and accessories e for desktop or plug-in application to make the final LED device.

These light devices can be combined with a preferred housing to become a final LED light device as shown in  FIGS. 12 and 13 . 
       FIGS. 12 and 13  show how to arrange the preferred embodiments of  FIGS. 7 ,  8 ,  9 , and  10  into a housing to become a final LED device with special effects. The device may have any of a switch, sensor, timer, control means, circuit, micro controller, IC, conductive means, motor means and power source to enable it to have a special LED light performance. 
     In the above-described embodiments, preferred images are created when the light device is activated by a switch, sensor, control means, power source, and circuit means. The light device can have any kind of design, shape, and display. The geometric shape of the substrate and spin means that incorporate the LED(s) or LED array may also be varied to provide a desired display of time, messages, words, colors, or patterns. 
     Although preferred embodiments of the current invention have been described above, it will be appreciated that all alternative or equivalent devices, functions, skills, arrangements, and constructions may still fall within the current scope of the current invention.
