Technical field
The utility model relates to a kind of with the light fixture of LED as light source, but relates in particular to a kind of LED lamp of multi-point touch.
Background technology
LED has energy-conservation, advantages such as the life-span long, the response fast, environmental protection, no stroboscopic as a kind of new type light source.At present, but the LED lamp of touch dimmer all is the luminosity of integrally-regulated light source on the market, adopts the light modulation of PWM technology mostly, realizes reducing brightness through the energising frequency that reduces the LED lamp.So after the brightness of LED lamp was turned down, stroboscopic appearred in the LED lantern festival, the infringement eye health.
Chinese patent publication number CN201967212U; Open day on 09 07th, 2011; The name of utility model is called the LED lamp of tangible light modulation, and this application case discloses a kind of LED lamp of tangible light modulation, and it comprises lamp outer casing and goes up power supply changeover device, constant voltage module and the switch light modulation coupling controller of mounted LEDs lamp string, the output of realization voltage; Switch light modulation coupling controller comprises touch light-adjusting module and the constant flow module that connects lamp outer casing; Touch light-adjusting module and be connected with lamp outer casing, touch light-adjusting module and be connected with the constant voltage module, the pwm signal output that touches light-adjusting module is connected with the signal input part of constant flow module; The voltage input end of constant flow module is connected with the voltage output end of power supply changeover device, and the current output terminal of constant flow module is connected with LED lamp string.Its weak point is, the LED lamp of this tangible light modulation adopts the light modulation of PWM technology, realizes reducing brightness through the energising frequency that reduces the LED lamp, and after the brightness of LED lamp was turned down, stroboscopic appearred in the LED lantern festival, the infringement eye health.
The utility model content
But the purpose of the utility model is to overcome existing touch dimmer LED lamp to adopt the light modulation of PWM technology; After the brightness of LED lamp was turned down, stroboscopic appearred in the LED lantern festival, the technical problem of infringement eye health; But a kind of LED lamp of multi-point touch is provided; It uses a plurality of led module LED light source consistings, and each the touch sensible dish on the touch pad is led module of control separately, regulates the luminosity of led light source through the amount of luminescence of control led module; Avoided having protected the health of eyes of user because of using the PWM technology to regulate the stroboscopic phenomenon that led light source occurs.
In order to address the above problem, the utility model adopts following technical scheme to be achieved:
But the LED lamp of a kind of multi-point touch of the utility model; Comprise the touch pad formed by several touch sensible dishes, induction process chip, CPU and several and corresponding drive circuit of touch sensible dish and led module; The input of said induction process chip links to each other with the touch sensible dish; The output of induction process chip links to each other with the input of CPU; The output of said CPU links to each other with several drive circuits respectively, and said several drive circuits led module of corresponding driving with it respectively link to each other.
In the present technique scheme; When the user touches the touch sensible dish on the touch pad; The touch sensible dish that is touched can produce a touch signal and send to the induction process chip, and the induction process chip receives this signal, and the corresponding data signal of touch sensible dish that generates and be touched.CPU reads this data signal from the induction process chip, and starts corresponding driving circuit, the touch sensible dish corresponding LED module of lighting and being touched according to this data signal.The CPU per second reads digital signal 10 times from the induction process chip; When the some touch sensible dishes on sustained touch touch pad of user surpass 5 seconds; The continuous data signal that read in 5 seconds of CPU all is the corresponding data signal of this touch sensible dish; CPU stops all drive circuit works, and all led modules extinguish.
Led module is made up of the LED more than 1 or 1.The user can light a led module arbitrarily as required, regulates the luminosity of led light source through the amount of luminescence of control led module.Because brightness remained at high-high brightness when the LED in the led module was luminous, do not regulate through the PWM technology, so there is not stroboscopic phenomenon, protected the health of eyes of user.
As preferably, said touch sensible dish is the capacitance touch inductive disks.The capacitance touch inductive disks need directly not contact with human body, can thoroughly eliminate safe hidden trouble, and is highly sensitive.
As preferably, the one side that said touch pad contacts with human body is provided with the insulation cover of being processed by insulating materials.Protection touch sensible dish can or not use for a long time because of the change of environmental condition and change, and improves the antijamming capability of touch sensible dish.
As preferably, said induction process chip adopts the ST08B touch inductor.The ST08B touch inductor can come inductance capacitance to change through any non-conductive medium with the capacitance variations of average capacitance value as the benchmaring induction point.
As preferably, said induction process chip links to each other through the I2C bus with CPU.The I2C bus has that interface line is few, and control mode is simple, the advantage that traffic rate is high.
The beneficial effect of the utility model is: use a plurality of led module LED light source consistings; Each touch sensible dish on the touch pad is led module of control separately; Regulate the luminosity of led light source through the amount of luminescence of control led module; Avoided having protected the health of eyes of user because of using the PWM technology to regulate the stroboscopic phenomenon that led light source occurs.
