Embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

This specific embodiment is only to explanation of the present utility model; it is not to restriction of the present utility model; those skilled in the art can make to the present embodiment the modification that there is no creative contribution as required after reading this specification, but as long as within the scope of claim of the present utility model, are all subject to the protection of Patent Law.

Embodiment: as shown in Figure 1-2, the touch-control LED light fixture that a kind of brightness is adjustable, comprises housing 1, and housing is provided with LED illuminating module, power supply 2 and brightness regulation control circuit, and brightness regulation control circuit comprises the touch-control circuit module 44 with Touch Zone 441.

LED illuminating module at least comprises two LED lamp bands in parallel, and each LED lamp band at least has a LED lamp pearl 111; In the present embodiment, LED lamp is with three groups, and each LED lamp band only has a LED lamp pearl 111.

Between a pair of adjacent LED lamp band, be provided with diode 3; Brightness regulation control circuit comprises the counter 41 with three decoding outputs 411 and a reset terminal 412, and touch-control circuit module 44 is for to counter 41 clock signals.

The positive pole of diode 3 is electrically connected on the collector electrode of a triode 42, and the negative electricity of diode 3 is connected in the collector electrode of another triode 42, and the base stage of two triodes 42 is electrically connected on respectively wherein two decoding outputs 411 of counter 41; Between remaining next decoding output 411 and reset terminal 412, be electrically connected with an application of logic circuit module 43, between the base stage of two triodes 42 and application of logic circuit module 43, be also electrically connected with delay circuit module 45.

Under the present embodiment closed condition, three decoding outputs 411 are all in low level state, when acting on Touch Zone 441, touch-control circuit module 44 sends first clock signal to counter 41, thereby make corresponding decoding output 411 output high level, make to be electrically connected on triode 42 conductings of decoding output 411, and the collector electrode of this triode 3 is because being electrically connected on the positive pole of diode 3, thereby makes corresponding LED lamp pearl 111 luminous; When again acting on Touch Zone 441, touch-control circuit module 44 sends second clock signal to counter 41, thereby make the decoding output 411 of previous high level output be converted to low level output, be electrically connected on triode 42 cut-offs of this decoding output 411, and make corresponding another decoding output 411 high level outputs, thereby make another triode 42 conductings, now triode 3 conductings, thus make corresponding LED lamp pearl 111 full-luminous; Thereby under the effect of twice touching signals, reach the effect of brightness adjusting; When again acting on Touch Zone 441, touch-control circuit module 44 sends the 3rd clock signal to counter 41, makes the decoding output 411 of current high level output be converted into low level, makes 42 cut-offs of corresponding triode, diode 3 not conductings, LED lamp pearl 111 is closed; A remaining decoding output 411 output high level, and nurse one's health by application of logic circuit module 43, to reset terminal 412 output high level, counter 41 is resetted, restart clock cycle counting; The setting of delay circuit module 45, can make LED lamp pearl 111 after luminous certain hour, automatically produces high level and nurses one's health by application of logic circuit module 43, to reset terminal 412 output high level, and then close LED lamp pearl 111, and counter 41 is resetted, restart clock cycle counting.
