Abstract
The utility model discloses a TV remote controller with a lighting function which has the advantages of simple structure and convenient use. The utility model comprises a power supply source of the remote controller, wherein the supply source is respectively connected with a control chip of the remote controller, a voltage stabilizing and charging chip and an electrical inductance of a voltage stabilizing and charging circuit, wherein the control chip (S3P825AXZZ) of the remote controller is connected with the input end of the voltage stabilizing and charging chip (SP6682). The output end of the voltage stabilizing and charging chip is connected with a field effect transistor in the voltage stabilizing and charging circuit, and a light emitting diode is arranged between a diode of the voltage stabilizing and charging circuit and a feedback resistance. The feedback resistance is connected with the feedback end of the voltage stabilizing and charging chip. The utility model reaches the actual effects of changing light and lighting, has the advantages of convenience and environmental protection and can replace a household flashlight for daily lighting.
Description
Technical field
The utility model relates to a kind of lighting technology, more particularly, relates to that a kind of energy consumption is low, the life-span is long, brightness is high, the LED lighting technology of scalable light intensity.
Background technology
Increasingly mature along with the LED lighting technology can reach the illuminating effect of common incandescent osram lamp.The more existing device that is used to throw light on based on light-emitting diode all is a ball bearing made using of directly controlling light-emitting component with load switch.The LED lighting technology is fit to cooperate with the semiconductor integrated drive electronics, can be positioned over to have now among the electrical equipment, thereby develop the new function of used household appliances.
The utility model content
Technical problem to be solved in the utility model is, utilizes TV remote controller, suitably increases circuit element, to LED drive and luminous intensity controlled, provide a kind of simple in structure, the TV remote controller that illumination functions is arranged easy to use.
The utility model has the TV remote controller of illumination functions, be achieved by following technical proposals, the power supply that comprises remote controller, described power supply connects remote controller control chip, voltage stabilizing charging chip, voltage stabilizing charging circuit inductance respectively, described remote controller control chip (S3P825AXZZ) connects voltage stabilizing charging chip (SP6682) input, voltage stabilizing charging chip output connects field-effect transistor in the voltage stabilizing charging circuit, between voltage stabilizing charging circuit diode and the feedback resistance light-emitting diode is set, described feedback resistance is connected with voltage stabilizing charging chip feedback end.
The utlity model has following beneficial effect: utilize the advantage that the power consumption of high brightness LED own is little, the life-span is long, luminous efficiency is high, control control energy in conjunction with TV remote controller, reached the actual effect that becomes optical illumination, convenient, environmental protection, the flashlight that can replace family is used for normal lighting to be used.
Description of drawings
Fig. 1 is a circuit block diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
On the circuit board of TV remote controller, install high brightness LED, voltage stabilizing charging chip SP6682 and peripheral circuit additional.The power supply (generally being provided by No. 5 AAA alkaline battery polyphones of two joint 1.5V) of remote controller can directly be provided the power supply of illumination driving circuit.
As shown in Figure 1, power supply connects remote controller control chip, voltage stabilizing charging chip, voltage stabilizing charging circuit inductance respectively, remote controller control chip (model is S3P825AXZZ) connects voltage stabilizing charging chip input, voltage stabilizing charging chip (model is SP6682) output connects field-effect transistor in the voltage stabilizing charging circuit, between voltage stabilizing charging circuit diode and the feedback resistance light-emitting diode is set, described feedback resistance is connected with voltage stabilizing charging chip feedback end.
The utility model adopts voltage stabilizing charging circuit to provide stable direct current biasing for high brightness LED.When " pattern " key of pushing on the remote controller, when switching to " LED " state (can by the LCD display window on the remote controller observation), press " power supply " key after, the light-emitting diode conducting is luminous, plays illuminating effect.This moment, design was 20 milliamperes by the electric current of LED.In order to satisfy of the requirement of different occasions to illumination, can be under " LED " pattern, by pushing " sound/LED " control button on the remote controller, regulate the PWM input signal on voltage stabilizing charging IC (Enable) pin, with this electric current that flows through LED is changed in 15 to 30 milliamperes of scopes, reach the purpose that light-emitting diode luminance is regulated.Simultaneously, in voltage stabilizing charging circuit,, can make the current stabilization of the high brightness LED of flowing through, prevent the generation of flickering phenomenon by introducing voltage negative feedback VFB.
Embodiment recited above is described the utility model preferred implementation; be not that design of the present utility model and scope are limited; under the prerequisite that does not break away from the utility model design philosophy; common engineers and technicians make the technical solution of the utility model in this area various distortion and improvement all should fall into protection range of the present utility model.
