The essence of the invention

The task to which the declared solution is directed is the development of a pocket flashlight with the ability to turn on / off the flashlight and adjust the brightness of the LED using the wheel-button.

The task is solved due to the design of the wheel-button, the axis of which is located on supports with the ability to perform reciprocating and rotational movements, under the axis of the wheel-button there is a button to turn on the flashlight, and an analog sensor is located on the axis of the wheel-button.

The torch has a battery compartment (3) of FIG. 1, 2 inside which the power supply is located. The battery compartment (3) is interfaced with the electronic control unit (2) of the flashlight.

Electronic control unit (2) of FIG. 1, 2 on the opposite side of the battery compartment (3) is mated with the light emitting head (1). Inside the housing of the electronic control unit (2) is the board (2.1.5) of Fig. 4 with a microcontroller (2.1.6) performing the function of a pulse adjustable voltage converter to adjust the brightness of the LED.

On the upper periphery of the electronic control unit housing (2) of FIG. 1, 2 there is a hole from which part of the button wheel (2.1) protrudes. The button wheel (2.1) is located along the longitudinal axis of the lamp.

The push button wheel (2.1) of FIG. 4 is interfaced with the board (2.1.5) with a microcontroller (2.1.6) through the supports (2.1.1) of FIG. 3 in which the axle (2.1.2) of the wheel-button (2.1) is installed. Supports (2.1.1) Fig. 3 allow the axles (2.1.2) of the wheel (2.1) to perform linear reciprocating and rotational movements. On one side of the wheel-button (2.1) under its axis (2.1.2) on the board (2.1.5) there is a clock button for switching on (2.1.3) of the flashlight in such a way that during the linear-translational movement of the wheel-button (2.1 ) the edge of the axle (2.1.2) of the wheel (2.1) interacts with the power button (2.1.3), as a result, a signal is sent to the microcontroller (2.1.6) of Fig. 4 controls to turn on / off the LED. The power-on clock (2.1.3) of FIG. 3 is a digital sensor. - While the button (2.1.3) is not pressed, the sensor outputs a logical unit, when the button (2.1.3) is pressed - logical zero. On the opposite side of the button wheel (2.1) of FIG. 3 on its axis (2.1.2) there is an analog sensor (2.1.4). The output result of the sensor (2.1.4) is an analog signal with a voltage level directly proportional to the turning angle of the button wheel (2.1). The analog signal from the sensor (2.1.4) of Fig. 4 is transferred to the microcontroller (2.1.6). The microcontroller (2.1.6) changes the brightness of the LED from the current position of the wheel-button (2.1).

The analog sensor (2.1.4) of Fig. 4 is connected to the microcontroller (2.1.6) by three wires or tracks on the board. The power output, ground, analog pin of the microcontroller (2.1.6) are connected to the analog sensor (2.1.4). The power button (2.1.3) is connected to the microcontroller (2.1.6) by three wires or tracks on the board. The power output, ground, digital pin of the microcontroller (2.1.6) are connected to the power button (2.1.3).

This design of the wheel-button allows you to turn on / off the flashlight by pressing the wheel-button and change the brightness of the flashlight by rotating the wheel forward / backward.

In the particular case of execution on one side of the button wheel (2.1) of FIG. 3 under its axis (2.1.2) on the board (2.1.5) next to the power button (2.1.3) there is an LED. On the opposite side of the wheel-button (2.1) under its axis (2.1.2) on the board (2.1.5) opposite the LED there is a phototransistor. The push button wheel (2.1) has transparent parts and is installed between the LED and the phototransistor. When the opaque part of the button wheel (2.1) blocks the light emitted by the LED, the conductivity of the phototransistor changes. This change is detected by the microcontroller (2.1.6) of FIG. 4. The microcontroller (2.1.6) changes the brightness of the LED from the current position of the wheel-button (2.1).

In another particular case of execution with the opposite from the power button (2.1.3) of FIG. 3 sides of the button wheel (2.1) on its axis (2.1.2), there is a metal plate in the form of a circle with serifs. Opposite the plate on the board (2.1.5) there are two pairs of contacts. The plate in the form of a circle with serifs, which is located on the axis (2.1.2) of the button wheel (2.1), rotates synchronously with the wheel (2.1) and interacts with a group of contacts. The group of contacts and the notched plate are connected to the microcontroller (2.1.6) of FIG. 4. When rotating the button wheel (2.1) of FIG. 3, each pair of contacts is closed and opened by a notched plate, but these pairs of contacts are located in such a way that when the wheel (2.1) rotates in different directions, the order of closing / opening the contacts is different and, thanks to this, the direction of rotation can be determined. This direction is determined by the microcontroller (2.1.6) of FIG. 4.

The microcontroller (2.1.6) changes the brightness of the LED from the direction of rotation of the wheel-button (2.1).

The light emitting head (1) of FIG. 1, 2 is a hollow cylindrical casing. The light emitting head (1) is connected to the electronic control unit (2). On the opposite side from the electronic control unit (2), the light-emitting head (1) has a lens. For the manufacture of lenses used transparent homogeneous materials such as glass, optical glass, optically transparent plastics and other materials. Next to the lens, inside the light-emitting head (1), is a reflector. Plastics or metallic materials are used to make the reflector. The reflector is tapered. An LED is installed in the center of the reflector.

The technical result consists in the possibility of turning on / off the flashlight and discretely changing the brightness of the LED by the wheel-button due to the fact that the axis of the wheel-button is located on the supports with the ability to perform reciprocating and rotational movements, a button for turning on the flashlight is installed under the axis of the wheel, and on the axis the wheel-button is an analog sensor.

Implementation of the declared decision:

The stated solution works as follows.

To turn the flashlight on / off, press the button wheel (2.1) of FIG. 1, 2. The axis of the button wheel (2.1) of FIG. 3 performs a linear reciprocating movement and interacts with the clock button (2.1.3) of the flashlight, which is located on the board (2.1.5) under the axis (2.1.2) of the wheel-button (2.1), as a result, a signal is sent to the microcontroller (2.1 .6) fig. 4 controls to turn on / off the LED.

To change the brightness of the flashlight LED, rotate the button wheel (2.1) of Fig. 1, 2. To increase the brightness of the flashlight LED, the button wheel (2.1) is rotated forward along the longitudinal axis of the flashlight towards the light-emitting head (1). To decrease the brightness of the flashlight LED, the button wheel (2.1) is rotated back along the longitudinal axis of the flashlight towards the battery compartment (3). The analog sensor (2.1.4) of Fig. 3 on the axis (2.1.2) of the wheel-button (2.1) transfers to the microcontroller (2.1.6) FIG. 4 analog signal with voltage level directly proportional to the turning angle of the button wheel (2.1).
