The first cylindrical platform of the convex lens (1, 2) may be provided along an edge portion of the convex lens (1, 2) as shown in Fig. 11.

As shown in Figs. 14-20, still another aspect of the invention provides an adjustable focus LED spotlight from inside of LED light bulb or fixtures with interchangeable bulb.

Conventional LED lighting devices that are equipped with adjustable focused spotlights are controlled mainly from outside of the body. The devices that are equipped with adjustable focus light beams can be found on flash light or on some other

lighting fixtures. But these are mainly controlled from outside that will change the length of the controller and thus the device will looks protrude from the main body of lighting device and looks not appeasing to the eyes. And since it is specially designed for the limited usage and restricted purpose, it is expensive. Another issue can be found in PAR light bulbs that has limited space from outside body and will be difficult to apply the adjustable focus LED light beam mechanism on outside of the body of light bulb. Current LED bulb and driver are attached and glued together and cannot be adapt/fitted to or with other type and shapes of bulbs.

To solve the above problems, the invention provides an adjustable focus spotlight on the inside the body of light bulb or fixtures. Since the adjustable focused lighting handle (102) is located inside the bulb or fixtures, it looks natural and looks just as same as other regular type of bulb or fixtures. The converging lens (101) is located inside the body of

bulb/fixture and can be controlled the spreading of angle of the light by zooming in or out the converging lens. By zooming in and out the handle (102), it can provide either clear

directional narrow focused spot light or wide spreading flood light .

Zooming in and out can be done in: turn clockwise or counterclockwise along the thread line; or it could also be pushed in or out; or stepping click in or stepping click out.

By providing the adjustable focus LED light handle inside the PAR bulb, it can easily and freely be able to focus the light from intense direct narrow angle focus light beam to wide spread of flood light easily. Thus, there is no need to purchase spot light or flood light on each different usage. Another advantage of this current invention is that many different shape of type of bulbs can be fit into same standard Edison base.

Since the top part of the bulb shape can be easily attached or detached with many different type of shape of bulbs, it can be adapt into different design (126-132) and looks that fits on different occasion. When the bulb cover (113) and bottom of bulb shape that screw into the body of base (107), the gasket (104, 116) is provided to prevent the water or moisture getting into the device. When top part of cover (113) needs to be unscrewed, it can also unscrew the bottom base screw (111) at the same time. It can be prevented by providing secure lock (106) on standard base (107) that will prevent the turning of both top cover (113) and bottom screw base (111) at the same time. The bulb base (111) will be loosened only when the body of bulb (126-132) is pressed down and turn counterclockwise.

The bottom base (from 111 and 108)

- can be turn clockwise or counterclockwise according to thread for fastening or detaching each other,

- can be plug in or plug out for fastening or detaching, - can be step in or step out for fastening or detaching each other,

- can be click in or click out it for fastening or detaching each other.

Another advantage of this invention is it doubles the brightness by using light comes out through converging lens and it adds brightness through reflection on reflector (112) .

Another advantage to use focus light is that it can be also applied in motor for controlling the focus of light. Motor can control individual LED light (Fig. 15) or it can control all lights at the same time by gear belt. Another advantage of the invention is to provide a front cover (113) that can be replaced with different type of cover. It can be switched to transparent, or clear or foggy or textured or choice of colors or designs.

The top cover (from 113 and 126 and other shapes)

- can be turn toward clockwise or counterclockwise toward the thread direction for fastening or detaching,

- can be screwed into the top round edge (115) of bulb shape for fastening or detaching,

- can be step in or step out by pushing in or pulling out for fastening or detaching each other.
