In addition, the Inventor's U.S. Pat. Nos. 5,926,440; 6,158,868; 6,170,958; 6,171,117; 6,280,053 disclose arrangements of conductive means for night lights and multiple function night lights incorporated time pieces. Other U.S. Pat.

The current invention offers a big improvement in power saving because it incorporates the low power consumption Light Emitting Diode (LED) to replace the incandescent bulb which normally uses a 4 Watt or 7 Watt or more power consumption light means. A single LED normally has a 0.3 Watt+/−100% power consumption depending on the product design and illumination needed.

The current invention not only provides a power saving device but also reduces a consumer's monthly electricity expense. The current invention also supplies two or more additional practical functions to the consumer, which may selected from, for example, an air-freshener and/or (as described in co-pending U.S. patent application Ser. Nos. 11/527,631; 11/527,629; 11/498,881; 11/498,874; and Ser. No. 11/527,628; etc.) an adaptor device, sonic device, frequency device, bug repeller device, second light device, timepiece, electric message device, timer device, temperature device, surge protection device, electric short circuit protection device, base device for installation on an existing lamp socket, emergency light device, or any other electric device(s) used in a home to keep people comfortable or safe.

This current invention optionally may further incorporate the teachings of the co-pending application entitled “LED night light with more than one optics means” concerning the inclusion in the LED night light of an optical element that improves the visibility of light beams from the LED.

All existing LED nightlights have the big problem that the LED unit can be seen by a viewer over a narrow viewing angle only, and that the brightness over that angle is too strong, resulting in spot-light effects (super bright in a small area). The co-pending application teaches multiple (more than one) optics means to provide a big improvement from spot light to linear or area brightness, thereby causing the spot-light effects to change to a nice looking lighting effect such as that provided by a fluorescent tube. It is very difficult to use only one piece of optics means to cause the strong spot-light LED unit(s) to have nice and warm light effects that can be seen by a viewer. This is a big improvement in the LED night light.

The current invention further adds some other arrangement such as reflector(s), bubble(s), or lens(es) within any of the optics element(s) or optic-lens to increase the effects of modifying the narrow viewing angle light beams emitted out of the LED(s) to provide linear or area light effects.

Furthermore, the current LED night light invention solves several problems with the most popular night light in the marketplace. The most popular night light length is around 88 mm+/−50 mm (with base), The outer optics-lens or optical elements or expose wall height is around 60 mm+/−30 mm (without base). The height from the wall outlet cover is around 35 mm+/−15 mm (from outlet cover surface). If the LED unit is placed on the same location as the outlet cover surface, the distance from the wall to the outside of the optics-lens or optical elements or expose wall will be less than 35 mm+/−15 mm, which is too short to eliminate the spot-light LED's into a surface or area photometric or lighted area having illumination without super bright spot(s)-light. The problem is solved by using two optics-lens or optic-element(s) or-and exposed wall(s) to get a good surface or area lighting effect with super bright lighted spot(s) or even brightness performance on the outer optics-lens, or exposed wall or optical-element(s). In addition, the LED night light power consumption will fall within the 0.3 W+/−100% per LED range, whereas the power consumption of a bulb night light falls within 4 Watt+/−50% per bulb. So, the LED night light will have a big power saving and reduce the monthly electric bill for the consumer.

The current invention not only provides a simple multiple function LED night light, but also provides excellent light performance. The LED night light with more than one function can add any function selected from, by way of example, an adaptor device, motion sensor device, PIR sensor device, air freshener, second light device, bug repellent device, sonic repellent device, surge protection device, emergency light device, time device, timer device, or any combination so the LED night light can be have nice light performance with more than single functions.

FIG. 1 shows a first preferred embodiment of a multiple functions LED night light in which the added function is adaptor device. The added function(s) may alternatively be selected from the devices described in co-pending U.S. patent application Ser. Nos. 11/527,631; 11/527,629; 11/498,881; 11/498,874; and 11/527,628 etc.), such as an air freshener, adaptor device, sonic device, frequency device, bug repeller device, second light device, timepiece, electric message device, timer device, temperature device, surge protection device, electric short circuit protection device, base device for installation on an existing lamp socket, emergency light device, or any other electric device(s) suitable for home use to keep people comfortable or safe. The added function(s) may be one to N (any number) to make a very practical multiple functions LED night light.

As shown in FIG. 1, the multiple function LED night light (1) has a back housing (10) assembled with a front housing (20) and arranged to capture prong means (30) (30′) (31) within and enable delivery of electricity from the outlet power source to the other electric appliance device. An optics means (40) exhibits light effects from the inner LED or LEDs to provide a light performance having predetermined functions, time, duration and so forth as required.

FIGS. 2-4 show the multiple function LED night light of FIG. 1 from different viewing angles. Fig. shows details of the inner construction of the multiple function LED night light (5) which has a back housing (100) and which holds an optics medium (400) having a ring design which is adjacent a circuit board (50) connected to prong means (300) (300′) to deliver input home electricity to the LEDs (60) (70) and cause the LEDs (60) (70) to emit a light beam into the optics means (400) from the two input ends (60′) and (70′). The preferred input ends are “U” shaped so as to allow as many of the light beams emitted from the LEDs (60) (70) to enter the optics means as possible. Some applications may have other designs for the optics means' input ends, which is not a limitation for the current invention's preferred embodiment description. The input ends design can be any type which is still within the current invention scope. The prong means (310) is a grounded type to provide more safety for the adaptor device. This prong arrangement can be varied depending on the different requirements of safety authorities or governments.

The optics means of FIG. 5 may have different arrangements that use sand-blasting to make the surface very rough and allow all the light to travel within without excess leakage, or use a plurality of the air-bubbles (or equivalent reflectors) inside the optics medium to cause light beams from the LEDs to exit the optics medium with splendid bright spots showing along the length of the medium.

As shown in FIG. 5, the circuit (50) may incorporate desired electric components selected from the group including, alone or in combination, at least one resistor, capacitor, switch means, sensor means, diode, inductor, transformer, integrated circuit (hereafter as IC), or any available components suitable for electrically driving LED(s) to have predetermined functions, duration, time, effects, and/or brightness.

• • The appropriate conductive piece used for the electric connection to the prong means (300) (300′) (310) and LEDs (60) (70). can be obtained from the marketplace and may include electric wires, and/or a harness, cable, spring, metal piece, or other conductive means without departing from the scope of the invention, as long as an electric signal can be delivered from the circuit (50) to the prong means and LEDs means.

FIGS. 6-10 show the same features as FIGS. 1-5, the only difference being the different housing and optic-lens design with different space to arrange the LEDs, prong, circuit, and added device(s) on the LED night light.

From FIG. 6, The said LED light has base (6a) has circuitry inside to change AC current from outlet into desired current for inner LED or LED(s) light source(s) to tum-on and tum-off with desired functions. The LED or LED(s) light-beam emit to the 2^nd preferred optic-lens or optics-element (6d) (6c) which has same or different treatment(s) to make the narrow emit-angle LED or LED(s) light beam to spread out to whole or big-size surface of the said optics-lens (6d) or optics-element (6c) and the different with optics-lens (400) at the shape and inner construction.

The said FIG. 5 is solid and circle or donut or arc shape and is solid-piece without any hollow-inside or space-inside to add parts inside and optic-lens (400) emit light from whole body or length to let people see the illumination for big-area(s) not the ends. The optics-lens (6c) and (6d) same as the FIG. 5 the lens surface has desired treatment including same as FIG. 5 sand-blaster or other textures or marking or reflective surface(s) to make the narrow emit-out LED light beams to passing through or reflected or had tube on top with extra-piece to make the light-beam to be seem on whole surface of the optics-lens (400) or (6c) (6d).

From the FIG. 6 optics-lens (6c) or (6d) is not a solid tubular piece and it is a slim curve piece to save plastic expensive cost but can spread-out LED light-beam to whole or big-size surface. From FIG. 6 can see LED narrow emit-out light beam through the optics-lens (6c) (6d) spread out to wider areas as FIG. 7 (7b).

From FIG. 8 show the optics-lens (8g) is one of even-thickness for substrate and has preferred textures or marking or optics-designs (not shown but same FIG. 5 optics-lens (400) has sand-blaster or treatment) on the one or two surface of the optics-lens (8f)(8e) substrates (8g).

From the FIG. 9 show the Big recess area illumination (9a) which change from the narrow emit-out LED light beam while light beam passing through the front the 1^st optics-lens (9b) or-and emit to recess 2^nd optic element (9a) or-and side wall(s) (9c) to become wider spread-out light-beam to make wider-area can see the recess area (9a) illumination. The said added function or-and 2^nd electric-functions can like the ports (9d) (9e) or adaptor-hole (9f) which also can be 3 female prongs receiving outlets (same as FIG. 1 to FIG. 5) to allow other electric-device 3 male-prongs to insert as FIG. 1 to FIG. 5 shown.

The said ports (9d) (9e) or adaptor-hole (9f) also can be any other 2^nd functions as above discussed (i) to (xv) 15 preferred type of the 2^nd electric functions. From FIG. 10 show the preferred embodiment has recess 2^nd optic elements surface(s) (10b) (10c) which has desired texture or polished or smooth treatment, optics-design to make desired recess areas has illumination from inner LED or LED(s) in any type and combination with desired circuitry to make desired light-show.

FIG. 11 shows a multiple function LED night light, in which the added function (801) can be selected from the group including any combination, as disclosed in co-pending U.S. patent application Ser. Nos. 11/527,631; 11/527,629; 11/498,881; 11/498,874; and 11/527,628 etc., of an air freshener, adaptor device, sonic device, frequency device, bug repeller device, second light device, timepiece, electric message device, timer device, temperature device, surge protection device, electric short circuit protection device, base device for installation on an existing lamp socket, emergency light device, or any other electric device(s) suitable for home use to keep people comfortable or safe. FIG. 12 also shows a multiple function LED night light whose added functions can be selected from the above listed functions.

FIG. 13 shows a multiple function LED night light in which a special LED bulb (13) is included in the existing multiple function bulb night light housing with added function (13′). The multiple function LED night light of FIG. 13 has at least one LED device installed on a geometric base that also has the added electric, mechanical, or chemical function. The base also has a bulb socket to accept the conventional bulb base, which may select from a screw type, pin type, rivet type, or knob type. The LED device has built-in circuit means to change the bulb's electric signal to an LED's electric signal so as to turn on the LED(s) to exhibit predetermined function, duration, time, and/or brightness and light effects.

As shown in FIG. 13, the base (13′) has a bulb socket (80) and added adaptor function provided by the adaptor receptacles (3000) (3000′) (3100), which offer electricity to other electric appliances while the prong means (3200) (3200′) are connected to the wall outlet. At the same time, while prong means (3200) (3200′) are connected with the wall outlet power source, the bulb socket (80) also will receive the wall outlet power source electric signal, which in the USA is around 110 Volt, 60 Hz, to turn on the bulb inserted into the base. On the other hand, specially designed LED device (13) has a built-in circuit to change the wall outlet power source of 110V AC, 60 Hz to the working voltage and frequency of the LED(s) with desired control means such as a photo sensor, PIR sensor, manual switch, or other control means available in the marketplace to turn on LED(s) according to pre-determined functions, brightness, duration, and time.

The LED device (13) that fits into the bulb socket (80) has a base type (81) which may be but is not limited to a screw type base as shown in FIG. 13. The bulb base (81) has two electric terminals (83) and (82) to connect with electric signal electrodes through an inner lamp holder (not shown) which is connected with a prong means (3200) (3200′). The electric signal from the two electric terminals (83) and (82) is supplied to the circuit board (81′), which changes the electric signal from home appliance electric current to LED working current and turns on the LED (85) for single color or multiple colors to provide a desired light performance. The LED (85) is located on the side of the circuit board (81′) and connected with the bulb base electric terminals (82) (83) by conventional conductive means in circuit board (81′). The electric components (88) (85) may be installed on the circuit board (81′) or connected by conductive means (87) (84) away from the circuit board (81′) because some components may be too big and unable to fit within the bulb base (81). The circuit board (81′) is a narrow or elongated board inserted into the bulb base (81), which is different with the prior art U.S. Pat. No. 6,227,679 (Zhang et al.) issued on May 8, 2001. The Zhang patent discloses a circuit board located on the top of the base, in a vertical relation to the circuit board and base. Also, in the arrangement of Zhang, the LEDs are not located on one side of the circuit board but rather are applied on the circuit board with a certain angle to the circuit board surface. This is because Zhang does not realize that the distance between the LED tip and the top cover is way too close and it is impossible to eliminate the spot-light problem of an LED light beam therefore cannot get a good light performance on the bulb surface. The current invention uses the invention described in one of the copending applications listed above, of an LED night light with more than one optics means, to make the spot-light beam into an area-light by first optic means. By adding a second optics means, the light beams brightness will be very close at every point on the desired area or surface.

As shown in FIG. 13, LED (86) on is situated on the edge of the circuit board (81′) and positioned such that light beams from the LED are input to the first optics means (89) to cause the light beams to travel within the first optics medium (89). The top may use a dome shape design or a “V” shape design to collect light beams that hit the top area of the first optics medium. It will be appreciated that all equivalent treatments such as metallization of the top area or adding reflective arrangements within the first optics medium will be still fall within the scope of the invention. The LED device (13B) with screw type base can fit into a bulb night light's base socket (80) to replace the bulb and let the existing bulb night light become an LED night light without having to purchase a brand new unit to save money and change the big power consumption device into a lower power consumption device in seconds.

FIG. 14 show the Parent filing case for (# FF-4) (# FF-3) (# FF-2) (# FF-1) and (# II-2009) (# II-II) is the (# Q-07) as above discussed so not discuss more details here. Which also is parent filed case of (# R-2007) which is filed on same date of (# Q-2007) which is parent of division filed cases of (# R-1) (# R-2) (# R-3) (# R-4) (# R-5) (# R-6). From FIG. 30 show the background discussed the co-pending case (# R-6) (# R-5) (# R-4) (# R-2) (# R-2007) for LED night light has more than one optical element(s) as drawing FIG. 14 show details abstract which has 1^st (31) and 2^nd (30) optics-element(s). Where the said 1^st (31) optic-element(s) have at least one function(s) select from (i) to eliminate the at least one LED(s) (36) super brightness spot-light(s) to none super brightness spot-light(s) or very close even brightness, (ii) prevent people from touch LED(s) (31) or inner electric parts (34) on PCB, (3) allow the LED(s) light beam to passing through.

One of preferred embodiment, from FIG. 14 show the 1^st optics-element or optics-lens is one of tube construction. It is appreciated the 1^st optic-lens can be any construction such as dome (short of tube (30)), cone (sharp top of tube (30)), partial circle (half of tube (33)), curved piece (less than ½ tube (30)), flat piece; with or without air-bubble (33), reflectors (33), reflective, refractive, reflective and refractive optics-properties.

One of preferred embodiment, from FIG. 14 show the 2^nd optics-element or 2^nd optic-lens or 2^nd outer piece is one of detachable, separated piece which at least lack of one of (i) rear housing, (ii) side housing, (iii) rear and all sides housing; with or without at least one of (aa) U-shape or other-shape opening, (bb) built-in or add-on clipper, (cc) geometric shape clipper to clip-on or push-tight or assembled with base (2b) neck or groove or ditch (38).

One of preferred embodiment, from FIG. 14 show the said LED night light has built-in at least one of 2^nd LED(s) or more LED(s) to create at least one preferred light functions or performance for examples (i) color changing, (ii) color selection, (iii) brightness adjustable, (iv) fade-in or fade-out, or (v) other LED light function(s) or effect(s) available from marketplace while incorporate with at least one of (aaa) sensor (37), (bbb) IC on PCB, (ccc) switch(s), (ddd) wireless controller, (eee) slide switch.

From FIG. 14 also disclosure the said LED night light have at least one of additional functions, or features select from

(additional 1) outlet(s), or female receiving end(s), or terminal(s), or output(s), or port(s). as co-pending (# R-2007 U.S. patent Ser. No. 11/806,285 filed on May 31, 2007 same date of FIG. 30 which is (# Q-2007)).

(additional 9) any electric function(s) or features(s) combination from marketplace 1.

This arrangement solves the problem with the arrangement disclosed in the Zhang patent cited above that there is not enough space in a night light having the most popular dimensions to achieve a good area lighting effect. The most popular night light length is around 88 mm+/−50 mm (with base). The lens height is around 60 mm+/−30 mm (without base). The distance from the wall outlet cover to the highest point of the night light edge is around 35 mm+/−15 mm (from outlet cover surface). If placed in the same location as the existing bulb night light, the distance from the bulb socket to the wall outlet surface will be less than 35 mm. This distance from the wall to outside of the lens will only be less than 35 mm+/−15 mm. It is too short to change the spot-light effect of the LEDs into a surface or area lighting effect. The solution, as disclosed in the co-pending application is to use two optics means to get a good surface or area lighted effect. This will be the best because LED night light power consumption falls within the 0.3 W+/−100% per LED range, whereas a bulb night light falls within a 4 Watt+/−50% per bulb range. As a result, the LED night light will have a big power saving and help reduce monthly electric bills for the consumer.
