All the LED(s) light source are install under the housing roof, not under visible top lens has hi-reflective surface, housing, walls, or PCB surface to make multiple times reflections and emit out from top lens only!! 
       From  FIG. 9  show to get sufficient brightness and even brightness for Big lit-areas arrangement. This only can use the soft and bendable PCB has desired number (No. from 1 to N, N=any number) of SMD LEDs on its surface so can make a circle or geometric shape to let all SMD LEDs face inward or outward to cover certain areas. All the LED light beam be reflected by hi-reflect surface, wall, housing, parts and no leakage out from top compartment so can offer the in-direct LED light beam emit out from top lens. If need brighter, can add SMD LEDs number because these in-direct LED light beam been traveling for multiple reflected so it will be very even and none bright-spots can be seen for soft light and good for people eye protection. 
       From  FIG. 9 , See the total 5 levels. Each level can have tall wall or not depend on design requirement. 
       From  FIG. 9  is desk top application or other camping application by battery which can offer great illumination and wider to cover not only 180 of front but also cover the sides illumination up to 270 degrees for whole angle. 
       From  FIGS. 9A-9D  show the illumination for top ceiling installation. Same the features are not only the front 180-degree flat top-lens can emit light but also the sides can also emit light so can get 180 degrees flat+two side each may up to 45 to 60 degree=so total can add 90 to 120-degree top of the 180 degrees=300 degrees or other alternative design for angles. So it an offer walking closet or front door or garage or patio or garden for top installation ceiling light has 4 to 20-inch diameter or other geometric shape lit-areas with one or more than one levels/steps for in-directly LED light beam. 
       From  FIG. 9B  show the increase each level or steps height so can make variety of design. 
         FIG. 9E  show the alternative and same as above has in-direct LED light beam to the top lens but not under cover, housing, roof of housing or parts. The SMD LEDs is install on flexible PCB or substrate so can bendable into circuit shape install on the housing groove to emit the light inward or outward depend on where need to light. It also has the hi-reflective surface or walls or top cover to make multiple times reflection within the top compartment which has no light beam leakage out. 
         FIG. 9F  show the same as the  FIG. 1  to  FIG. 6  all related drawing which PCB is hard piece and has top cover, roof, housing, parts to prevent light beam direct to see from top lens. 
       However, for Big lit-areas to has even and super strong light brightness and even photometric, this is not workable so this treatment only can apply for the LED light lit-area less than 4-inch diameter or same square lit-areas for geometric shape for lit-area. Bigger than 4 inch diameter up to 20 inch for lit-area only can use the  FIG. 9-1  or following  FIG. 9  for LED-assembly or more than one of LED assembly to get big lit-areas or multiple level lit-areas or top/side illumination purpose. The hard PCB and SMD face up is too costly to make big areas illumination because bigger size PCB is more expensive. Especially the current requirement for all LEDs under cover, housing, parts to get the in-direct light beam show on the top lens so it is too costly for SMD LEDs all face up on hard PCB. 
       From  FIGS. 9G-9H  show the 5 level or steps top-lens has not only front illumination and also has good brightness emit from side so increase the illumination for more areas and not only front side of LED light. The  FIG. 9-3   a  which is shallow disk like top lens, not same as  FIG. 9-3   b  which each level or step has high wall so more look like 5 steps. 
       From  FIGS. 9I-9J  show other application for motion or moving detector(s) sensor ceiling light has 3 to 20-inch diameter for round or any geometric shape. Also the added functions or features is all same as co-inventor&#39;s earlier or pending filed case including it and all related parent filed case such as (# KKK) U.S. application Ser.

     These co-pending cases mainly for LED track light has removable or detachable LED-unit. The current invention makes the big improvement for power saving LED-unit, Super Slim LED-unit, Super easily attachable LED-unit by magnetic-reaction on track light. 
     Further incorporate with the different circuit or-and controller or-and update wireless communication not only the earlier parent case for Blue-tooth connection but also has incorporate with Wi-Fi, APP software, Server, Cloud, 4G/5G network to make more simple and easily and more selections control the (1) brightness (2) mixed color (3) dimmable (4) time period for illumination (5) instant white (6) 360 or more color mixer (7) add camera for MP4 image and sound (8) communication with phone or computer or communication equipment, consumer electric. 
     From Parent filed case and pending case the current invention also including the self-powered LED-unit so can have added feature for said track light LED light source and can carry to everywhere. (As #RR-2010 and #UU-2010). 
     From Parent filed and co-pending filed cases also has features for 
     From  FIG. 1  show the current invention has hi-reflective top cover ( 02 ) to assembled with base ( 01 ) and has top-lens ( 03 ) for form a finish products use for ceiling while it between 5 to 15-inch diameter with sufficient light brightness from 100 to 1,000 Lumens. While the size made from 1 inch to 6 inch can become parts of other main application such as LED-unit(s) for track light which has preferred installation or attachment with detachable features as co-pending or earlier flied case list above. 
     From  FIG. 2  show the thicker unit which is too bulky for user and look bad because has (1) thicker or too high (2) can see high bright-spots from lens while it lit (3) too much opaque or white painting or powder while injection or treated so inside light beam been block out up to 20 or up to 50% just only for not see the LED light spot. This is not power saving or not smart to make a LED light. From  FIG. 2  show the LED light source ( 04 ) is install on the bottom of base PCB ( 05 ). The reason why need to put PCB ( 05 ) as deep as possible because LED light source ( 04 ) is narrow light beam light source if need to get wider area (Top White circle area) been lighted need to have as long as distance from LED to light present location. From  FIG. 2  compare with  FIG. 3  which PCB ( 05 ) is put upper location so the lighted-area ( FIG. 3  top white circle is very small). From Both  FIG. 2  or  FIG. 3  because LED light source ( 04 ) all install under the top lens ( 03 ) and any LED light strong beam will still show out to people and that is not comfortable and hurt people eyes. From  FIG. 2  lower photo show the 3 batteries ( 06 ) arranged as triangle in order to let center space empty so a put the PCB as deep as to get wider lighted-area. However, from  FIG. 3  the battery is put on parallel so no space within the batteries so PCB ( 05 ) have to move up and this cause seriously tiny lighted-areas and super strong LED bright-sports, so only solution to get even brightness for whole top lens only can make top lens more white and which means need reduce a lot of brightness just make even brightness and no lighted spots. 
     From  FIG. 4 ,  FIG. 4-1 ,  FIG. 4-2 ,  FIG. 4-3 ,  FIG. 4-4  show the current invention optics design for LED position. Basing on market may need super bright LED light so may need use plurality of LEDs for offer sufficient brightness. The smartest way is use SMD (Surface Mounted) which can use automatically machine to install plurality of LEDs in seconds without any deviation, shortage instead of Dip type LED has 2 or more legs need soldering on PCB. From  FIG. 4 , the current invention prefers to use all SMD LED which is around 1×3 mm size by automatically installation. All SMD LEDs ( 04   c ) are install PCB ( 05   c ) and all LEDs ( 04   c ) is under the light block-out material top cover ( 02   c ) or housing ( 02   c ), so the LED ( 04   c ) light emit to up and do not be seen by people. 
     From  FIG. 4-1 ,  FIG. 4-2 ,  FIG. 4-3 ,  FIG. 4-4 ,  FIG. 4-5  show the same unit as  FIG. 4  just make parts larger and larger to show clear the top cover ( 02   d ) ( 02   g ) ( 02   e ) ( 02   f ) edge (dot-line) and LED(s) ( 04   d ) ( 04   e ) ( 04   f ) position. It also shown the Top lens ( 03   d ) ( 03   e ) ( 03   f ) and Top Cover ( 02   d ) ( 02   g ) relation. Here the slim LED light has shallow disk-like shape for cosmetic purpose. It can be totally flat for more fashion model and look more thin unit. 
     From  FIG. 4-5  and  FIG. 4-6  and  FIG. 4-7  show bigger size drawing to show the different top lens and top cover and LEDs location vs. top cover edge (Dot-line). And also show the PCB (circuit board) which is just under the LEDs and PCB is also act a divider to make the top compartment is totally sealed for light beam emission. All light beam only can be traveling within the top compartment which has only Top cover, Top lens, LEDs and one side of PCB. Also, the inner surface of top cover and one surface of PCB both preferred has hi-reflective property treatment such as inner surface of top cover is metalized treated as mirror like shinning and PCB top surface preferred use white color surface so any light emit out from LEDs will hit mirror like top cover with pre-determined angle so can get best light reflected to the top lens. Alternative the top cover can made out from metal material and still has mirror light for inner surface with preferred angle design so can max light beam reflected to the top lens. The top compartment has well design all light beam only can emit out from top lens. The top lens can be fully transparent so only has 1% or less % light loose because current invention all LED light source is not under top lens so no need a lot of texture or white painting to prevent people to see bright-spots. At this optics-design will get max. LED output light been applying for illumination only. The said the current invention has LEDs under light block-out roof plus hi-reflective housing or top cover can apply any LED light device. 
     From  FIG. 4-5-1  can see the relation of top lens ( 03 K) is a shallow dish-like shape and top-cover ( 02 K) which may made by metalized plastic or real metal piece has hi-reflective property which reflected LED ( 04 K) and emit to the top lens ( 03 K). The PCB ( 04 K) which become a divider to make whole top compartment has no any light beam leakage to lower portion or any other location. Any light beam will be reflected by mirror like hi-reflective surface including inside of top cover, housing and PCB top surface. 
     From  FIG. 4-6-1  can see the relation of top lens ( 03 L) is a totally flat shape and top-cover ( 02 L) which made of metalized plastic or real metal piece has hi-reflective property prefer like mirror and had optic angle calculation which has almost 45 degree so can get maximum reflections. The said top cover ( 02 L) can get maximum and best reflection. The LED ( 04 L) light beam has this 45 degree optics reflective angle so can get maximum light beam emit to the top lens ( 03 L). The PCB ( 04 L) which become a divider to make whole top compartment has no any light beam leakage to lower portion or any other location. Any light beam will be reflected by mirror like hi-reflective surface including inside of top cover, housing and PCB top surface. 
     From  FIG. 4-7-1  can see the relation of top lens ( 03 M) is a totally flat shape and top-cover ( 02 K) which made of metalized plastic or real metal piece has hi-reflective property prefer like mirror and can be any optic design or construction such as 90 degree or 45 degree or 60 degree or add a reflective wall surround all the LED-units. These four different optics-design has tiny difference as long as the top compartment is no any light beam leakage out and all light beam only emit from top lens ( 03 M). No any leakage light beam from top compartment so means all the light beam is traveling within only the top compartment and has multiple times reflected or-and refracted by the top lens, so all light beam from LED ( 04 L) almost 100% emit out from the top lens ( 03 L). The PCB ( 04 L) which become a divider to make whole top compartment has no any light beam leakage to lower portion or any other location. Any light beam will be reflected by mirror like hi-reflective surface including inside of top cover, housing and PCB top surface. The wall ( 07 M) install on the PCB ( 05 M) and wall ( 07 M) has height up to top cover so no any light beam will leakage from back all LEDs ( 04 M). 
     From  FIG. 4-5-1  and  FIG. 4-6-1  and  FIG. 4-7-1  also shown the how the top cover ( 02 K) ( 02 L) ( 02 M) to join with the PCB ( 05 K) ( 05 L) ( 05 M) for base wall ( 01 K) ( 01 L) ( 01 M) and also show the preferred battery in parallel arrangement so can leave two sides of body to install other electric parts and accessories such as Push on-off switch, motion/moving detectors sensor, IR or RF receiver, Wi-Fi receiver, Bluetooth receiver, photos sensor, IC, adaptor, rechargeable batteries. Power fail or other preferred added functions such as timer, dimmer, magnetic contactor, magnetic conductive-movable-piece or kits or set. mix color, color changing electric parts or accessories or related parts. 
     From  FIG. 5  show the 12 LEDs ( 04 R) install on 12/ 1/ 2/ 3/ 4/ 5/ 6/ 7/ 8/ 9/ 10/ 11/ 12 positions like clock dial face and each one is under the top cover roof (not shown) and all 12 LEDs ( 04 R) is surrounded by the hi-reflective wall ( 07 R) to make all the light beam only can travel within the inner space of the wall ( 07 R) or emit out from the top lens ( 03 R). The PCB ( 05 R) has the high-reflective white surface so any light beam emit into will be reflected to other direction and may through the top lens ( 03 R) and refracted out to viewer. The circuit board ( 05 ) in dodecagon shape or can be any shape to fit the top cover and lower base (not shown). From PCB ( 05 R) also can see the quickly connector set ( 08 R) which can connect to AC or-and DC power source, can deliver the electric signal, can link to other PCB, or link circuit, power, light source for more than one or more sets for a system.

However, to arrange battery terminals on the “U-shape” base ( 701 ) still fall within current invention scope. The other circuit or IC all install on the PCB (not shown) to offer the electric signal to turn on-off the LED light for all kind of pre-determined functions, effects, moving effects, color changing, dimmer, color mixed, chasing, sequential, timer, duty cycles, duration . . . etc. 
     The said several LED-unit ( 705 A) ( 705 B) ( 705 C) has magnetic contactor or magnetic conductive-movable-contactors on back which both has magnetic reaction for pair of magnetic buss-strip ( 702 ) magnetic-field. So easily to attach or detachable or add or remove the said LED-unit from the said top cover ( 702 ). 
     From  FIG. 7-1  show the top cover ( 702 A) has pair of magnetic buss-strips ( 703 A) ( 703 A′) which has magnetic field so can attach the LED-unit ( 705 D) ( 705 E) ( 705 F) by reaction of the said LED-unit back magnetic contactors or magnetic conductive-movable-contactors. The buss-strip ( 703 A) ( 703 A′) preferred has around 5 mm width to fit within the groove which may around 6 mm width and two end of buss-strips bend into 90 degree so can passing through the openings (not shown) under the end-cap ( 704 A) ( 704 A′) to connect with below PCB (not shown). 
     From  FIG. 7-2  shown the base ( 701 A) which can be one piece “U-shape” base ( 701 ) has two ends has door or covers to install or replace batteries. The battery ( 706 - 1 ) ( 706 - 2 ) ( 706 - 3 ) preferred is AA battery and put in parallel side by side around 5.2 mm (2 inch) that is perfect size for the track light width. The “U-shape” base is one piece or has alternative design which use more than one piece “battery-compartment” to form in same length of the base and each “battery-compartment” can has its own three piece AA battery inside with link-kits to link with other battery-compartments. The each “battery-compartment” also can change positions while needed, so this arrangement supply at least one of backup “battery compartment”. Same as the said track light it also can have alternative design to add link-kit so can link one track light to others track light to link to design length or-and turn angle to “L” or “Y” or other geometric shape. 
     From  FIG. 7-3  show the “battery compartment” ( 701 G) is install and designed on the one end of track light unit. This shown other alternative embodiment. 
     From  FIG. 7-4  show the preferred track light has four current inventions slim and none bright-spots LED-unit ( 705 J) which magnetic conductive-movable-contactors (not shown) on back so not only can attach to top cover ( 702 C) magnetic buss-strips ( 703 C) ( 703 C′) but also can deliver the electric signal to each attached LED-unit ( 705 J). The said LED-unit ( 705 J) has base ( 01 W) and top cover ( 02 W). The all LEDs of LED-unit ( 705 J) are install under the top cover ( 02 W) roof so LEDs cannot see from top lens ( 03 W) and PCB ( 05 W) is under the LEDs and other features as above discussed. 
     From  FIG. 7 -A,  FIG. 7 -B,  FIG. 7 -C,  FIG. 7 -D show the said LED-unit ( 705 K) ( 705 L) ( 705 M) ( 705 N) each has slim and non-bright-spots optics design as above discussed. Those also has different trigger to turn on-off LEDs which the said  FIG. 7 -A incorporate the push on-off switch which located under the top lens and whole top lens edge is connect with spring and switch bar whenever push the top lens can turn on or turn off the LEDs. It also can have upgrade model to have time delay or auto timer which when people forget to push top lens to turn off, the light will automatically to turn off after preset time period such as 5/10/15/20/25/30 minutes. 
     From the  FIG. 7 -B LED-units as above has back contractor incorporate with motion or moving detectors sensor or-and photo sensor. While motion or moving been detected by sensor or sensor-assembly the LED-unit will turn on with more upgrade model such as time delay, duration or even flashing or what kind of market available functions can also add into the said LED light or LED-unit circuit depend on market required. The motion sensor or moving sensor or photo sensor can install any location depend on for what areas need to be detected or simplest is use dome sensor can cover 360 degrees but it has defect for shorter distance, the panel type Fresnel lens not dome shape Fresnel has much far distance and also can trigger the two end of panel areas by special optics-design to increase the signal emit into Fresnel. The motion sensor incorporate with photo sensor will make more power saving while under bright environment the LED light or LED-unit(s) will not be triggered and waste battery or AC power energy for brighter environment. 
     From  FIG. 7 -C show the LED light or LED-unit has incorporated with IR or RF remote control system. The IR or RF receiver kits can install on LED light here is track light housing to control all LED-units or install on each LED-units to make only each one of LED-units. The IR had direction problem for receiving electric signal. The RF has better because less direction problem for receiving electric signal and also has longer distance but cost little higher. However, the update for wireless system which through Wi-Fi or-and APP or-and server or-and even cloud with 3G/4G/5G network that will make much more functions or selections or adjustment for color, brightness, color mixed, dimmer, timer, instant white, sensitivity, communication, auto changing color, trigger other pre-set functions. Also, while incorporate Wi-Fi and APP it almost is unlimited distance for unlimited functions which depend on what software or APP be programmed.
     From  FIG. 7 -D show the LED-unit has self-powered so the LED-unit move out from the magnetic buss-strip. The LED-unit can use it pre-set manual switch to turn on the LED-unit for pre-program function. While this kind of LED-unit has built-in battery, it also can have USB port to charge the inner built-in rechargeable battery. It also can act as USB power bank through most common type A USB-port to connect with two USB-plug wire set to connect with other electric device to supply the internal rechargeable battery power to other device. These USB relation application is update for people so the LED-units on the track light is no more just a light for limited place but also can remove or move out to use for anywhere plus the power bank functions. While it ran out built-in rechargeable battery energy can use USB wire to charge it anywhere so become a multiple function LED-unit for track light, for refrigerator or metal surface use, for car repair use, for car accident use as warning light, for camping use, for outdoor activity, for emergency power back to charge phone . . . etc.

     From  FIG. 7-6  show the magnetic contactor or magnetic conductive-movable-contactor on back of LED-unit ( 705 P) ( 705   q ) ( 705 R) for different distance with magnetic field from magnetic buss-strips ( 703 X) which inside groove of the top cover ( 702 E). 
     While the ( 705   p ) is far away the magnetic file, the contactor will fall-down to opening. 
     While the ( 705   q ) is just touch the magnetic field, the contactor will little pop-up. 
     While the ( 705 R) is fall almost touch the magnetic field, the contractor will totally pop-up to attach on the magnetic buss-strips and build up electric delivery. 
     From  FIG. 8-1 ,  FIG. 8-2 ,  FIG. 8-3 ,  FIG. 8-4  show all preferred current invention for slim and non-bright-spots LED light for Big size 6 to 15-inch diameter for ceiling light which has optional motion sensor install on the center and all LEDs install under the cover light block-out material so no LED can be seen from light output lens. While it became small size 1 to 5-inch diameter can become closet or under-cabinet light or living room punk light. While it more compact size can incorporate with main products such as become track light movable, attachable, detachable LED-unit. 
     From  FIG. 9 , See the total 5 levels. Each level can have tall wall or not depend on design requirement. 
     From  FIG. 9  is desk top application or other camping application by battery which can offer great illumination and wider to cover not only 180 of front but also cover the sides illumination up to 270 degrees for whole angle. 
     From  FIG. 9 b    and  FIG. 9 c    and  FIG. 9 d   , show the illumination for top ceiling installation. Same the features are not only the front 180-degree flat top-lens can emit light but also the sides can also emit light so can get 180 degrees flat+two side each may up to 45 to 60 degree=so total can add 90 to 120-degree top of the 180 degrees=300 degrees or other alternative design for angles. So it an offer walking closet or front door or garage or patio or garden for top installation ceiling light has 4 to 20-inch diameter or other geometric shape lit-areas with one or more than one levels/steps for in-directly LED light beam. 
     From  FIG. 9 b   , show the increase each level or steps height so can make variety of design. 
       FIG. 9-1  show the alternative and same as above has in-direct LED light beam to the top lens but not under cover, housing, roof of housing or parts. The SMD LEDs is install on flexible PCB or substrate so can bendable into circuit shape install on the housing groove to emit the light inward or outward depend on where need to light. It also has the hi-reflective surface or walls or top cover to make multiple times reflection within the top compartment which has no light beam leakage out. 
       FIG. 9-2  show the same as the  FIG. 1  to  FIG. 6  all related drawing which PCB is hard piece and has top cover, roof, housing, parts to prevent light beam direct to see from top lens. However, for Big lit-areas to has even and super strong light brightness and even photometric, this is not workable so this treatment only can apply for the LED light lit-area less than 4-inch diameter or same square lit-areas for geometric shape for lit-area. Bigger than 4 inch diameter up to 20 inch for lit-area only can use the  FIG. 9-1  or following  FIG. 9  for LED-assembly or more than one of LED assembly to get big lit-areas or multiple level lit-areas or top/side illumination purpose. The hard PCB and SMD face up is too costly to make big areas illumination because bigger size PCB is more expensive. Especially the current requirement for all LEDs under cover, housing, parts to get the in-direct light beam show on the top lens so it is too costly for SMD LEDs all face up on hard PCB. 
     From  FIG. 9-3   a  and  FIG. 9-3   b , show the 5 level or steps top-lens has not only front illumination and also has good brightness emit from side so increase the illumination for more areas and not only front side of LED light. The  FIG. 9-3   a  which is shallow disk like top lens, not same as  FIG. 9-3   b  which each level or step has high wall so more look like 5 steps. 
     From  FIG. 9-3   c  and  FIG. 9-3   d  show other application for motion or moving detector(s) sensor ceiling light has 3 to 20-inch diameter for round or any geometric shape. Also the added functions or features is all same as co-inventor&#39;s earlier or pending filed case including it and all related parent filed case such as (# KKK) U.S. application Ser.
