DETAILED DESCRIPTION OF THE INVENTION

[0015] Hereunder an embodiment of a touch control arched lamp will be described with accompanying drawings for illustrating technical features and structures of the present invention. It is to be understood that the technical features and structures of the present invention can be applied to touch control lamps of different shapes, e.g. linear shape, annular shape, triangular shape, etc.

[0016] Referring to FIGS. 1-2, a touch control arched lamp 10 according to a preferred embodiment of the present invention includes an arched shell 20, an arched light device 30, an arched light frame 40, a control device 50, and a speaker 60.

[0017] The arched shell 20 is composed of a translucent plastic top diffuser 21, a translucent plastic bottom diffuser 22, and two metal bases 23 and 24. The combination of the top and bottom diffusers 21 and 22 is shaped as a hollow arched structure, two ends of which are fixedly disposed on the two metal bases 23 and 24, respectively. That is, the top and bottom diffusers 21 and 22 combinedly form an arched tube having an outer surface 27 and an inside accommodation 28 as shown in FIG. 5.

[0018] Referring to FIGS. 2-4, the arched light device 30 includes an elongated rectangular circuit board 31, a line of top light sources 32 fixedly disposed on the middle of a top surface 311 of the circuit board 31, and two lines of bottom light sources 33 fixedly disposed along two long edges of a bottom surface 312 of the circuit board 31. There are forty-two top light sources 32 grouped in fourteen sections of the circuit board 31, and each section of the circuit board 31 is provided therein with a capacitive touch sensor 313. Each of the fourteen groups includes three top light sources 32 which are red, green and blue LEDs (RGB LEDs) and also called colored LEDs in the present invention. In other words, the RGB LEDs 32 in the same group are associated with the same capacitive touch sensor 313. The bottom light sources 33 are all white LEDs. The circuit board 31 is originally flat and becomes arched after being disposed on the arched light frame 40.

[0019] Referring to FIGS. 2 and 5, the arched light device 30 and the arched light frame 40 are disposed in the arched shell 20 and located between the top and bottom diffusers 21 and 22 at a distance. The arched light frame 40 is made of metal such as aluminum, which serves as a heatsink for dissipating heat generated from the arched light device 30 as well as a structural support for supporting the arched light device 30 in good position and shape, and includes two plates 41 fastened to two ends of the bottom diffuser 22 respectively and an arch 42 extending between the two plates 41. The arched light device 30 are fixedly disposed on the arch 42 of the arched light frame 40 in a way that two ends of the arched light device 30 are fixed to the two plates 41 respectively and the top and bottom surfaces 311 and 312 of the circuit board 31 face toward the top and bottom diffusers 21 and 22 respectively. Therefore, the light of the RGB LEDs 32 is primarily emitted toward a top surface 25 on the top diffuser 21. Besides, the white LEDs 33 are not covered by the arch 42 but located by two sides 421 of the arch 42, thereby primarily emitting light toward a bottom surface 26 on the bottom diffuser 22.

[0020] The control device 50 and the speaker 60, which are electrically connected with the arched light device 30, are disposed in the bases 23 and 24 respectively. The control device 50 includes rechargeable batteries (not shown in the drawings), a power jack 51 and a printed circuit board 52, on which electronic components, such as Microcontroller Unit (MCU), capacitive touch sensor, etc., are mounted, for controlling the light sources 32 and 33 and the speaker 60 to function in at least the following five modes. When the user plugs in the lamp 10, the speaker 60 will make a power-on sound. Then the user can select the operating mode of the lamp 10 by simply touching either one of the metal bases 23 and 24, which are provided therein with capacitive touch sensors. In other words, the bases 23 and 24 serve as switches of the lamp 10. Meanwhile, the speaker 60 will make sound for selecting mode. During any mode, double touching the base 23 or 24 will turn the lamp 10 off. The aforesaid and the following control logics are programmatically built in the MCU.

[0021] In a first mode, the RGB LEDs 32 display the full rainbow of colors and that rainbow of colors appear to slide slowly from left to right continuously, while the downward facing white LEDs 33 maintain a steady medium brightness. This mode provides some ambient light, while also proving a beautiful moving rainbow display.

[0022] In a second mode, the RGB LEDs 32 remain off, and only the white LEDs 33 emit white light. In this mode, holding any switch, i.e. the base 23 or 24, will cause all the white LEDs 33 to slowly dim to low brightness, then brighten slowly back up to full brightness, and continue to repeat this process until the touch is released, at which point the brightness will stay at that value.

[0023] In a third mode, the RGB LEDs 32 display the full rainbow of colors, and that rainbow of colors appear to slide slowly from left to right continuously, while the downward facing white LEDs 33 remain off. This mode provides a beautiful rainbow display, while not producing any ambient white light. This mode is excellent for going to sleep, or providing a mood display.

[0024] In a fourth mode, the white LEDs 33 remain off, and the RGB LEDs 32 perform a function called “painting,” that will be specified below.

[0025] Through the above-described arrangement of the arched sell 20 and the arched light device 30, the top surface 25 of the arched shell 20 is invisibly divided into fourteen touch control sections 251 associated with the capacitive touch sensors 313 respectively, as shown in FIGS. 1 and 6. When anyone of the touch control sections 251 is touched by the finger of the user, the associated capacitive touch sensor 313 can sense the touch to cause the control device 50 to control the RGB LEDs 32 accordingly. In other words, the touch control sections 251 can serve as switches SW1 to SW14 for controlling the associated groups of RGB LEDs 32.

[0026] In the aforesaid fourth mode, the switches SW1 and SW14 turn on to red color for example. Holding on to either switch SW1 or switch SW14 causes that switch (touch control section 251) to slowly cycle through all the colors of the rainbow, and releasing that switch causes the displayed color to be chosen. After choosing a specific color, when anyone of the touch control sections 251 is touched, the associated RGB LEDs 32 are switched on to show the chosen color. In other words, touching anyone of the switches SW1 to SW14 turns the switch (touch control section 251) to the chosen color. Such situation is like the finger magically becomes a paint brush (in a virtual manner) to put the chosen color on any switch (touch control section 251) the finger touches. Touching any switch (touch control section 251) that has the same color already turned on in that same chosen color, will cause it to turn off. Meanwhile, the speaker 60 will make sound for painting the switch.

[0027] In a fifth mode, the control device 50 can control the RGB LEDs 32 to provide interactive games, such as memory games, like Simon. Action games like a simple version of Pong could also be played.

[0028] In brief, the present invention provides on-board LEDs 32, 33 and capacitive touch sensors 313 spacedly and suspendedly arranged inside the shell 20. By means of touching a surface of the shell 20, which corresponds in position to one of the capacitive touch sensors 313, the LEDs associated with the activated capacitive touch sensor 313 may turn on and off. In particular, the touch control sections 251, i.e. switches SW1 to SW14, are defined on the top surface 25 of the outer surface of the shell 20 one after another in succession in a line. With this design, the touch control sections 251 (switches SW1 to SW14) can be sequentially touched by a user's sliding touch motion to turn on and off the top light sources 32 (RGB LEDs) in a sequential manner. Further, in the above-disclosed embodiment, the part of the shell 20 accommodating the circuit board 31 is realized as an arched tube. However, the aforesaid part may be realized as a straight tube, a circle tube, a wavy tube, etc. Besides, the touch control sections of the touch control lamp of the present invention are unlimited to be located on the top surface 25 of the shell 20, but may be located on the bottom surface 26 of the shell 20, i.e. the bottom surface 26 of the bottom diffuser 22, for example. In other words, the capacitive touch sensors 313 may be arranged to sense the touch on the bottom surface 26 of the shell 20 to cause the associated LEDs to turn on and off
