Description

SEMICONDUCTOR DEVICE

The utility model relates to electronic equipment and is intended for use in instrumentation, automation devices, burglar alarms, etc.

The floor is known) A conductor device containing a light guide, n crystals glued with glue and boiled on a circuit board with leads, placed in a colored diffusing lens from a compound that acts as a housing 1.

A disadvantage of the known device is that when it is used in burglar alarm devices with a flashing light effect, an additional external circuit for generating control signals is required, which complicates the device.

The purpose of the utility model is to expand the functional capabilities of a semiconductor device.

This goal is achieved by the fact that in the semiconductor device containing a light guide, a block of LEDs with crystals glued with glue and boiled on a circuit board with pressed terminals, and sealed with a transparent or light-scattering compound, an additional control circuit crystal is glued with glue and boiled on a board having three outputs, two of which are connected to two inputs of the control circuit, and the third is connected to the input of the LED block, the second input of which is connected to the output of the circuit government.

The introduction into the semiconductor crystal device of a control circuit with its connections, which serves as a periodic interrupter, made it possible to achieve a blinking light effect and thereby expand the functionality of the device.

Figure 1 shows the design of a semiconductor device; figure 2 is a structural diagram of the device; on figs - the structure of the control circuit.

The semiconductor device (Fig. 1) contains a circuit board 1 with three pressed terminals 2. On a circuit board 1 crystals 3 are glued and welded, forming an LED block, an additional crystal 4 control circuits and optical fiber 5. The whole structure is sealed with a transparent or light-scattering compound acting as a housing 6 .

The block diagram of the device (figure 2) contains a control circuit 7 and a semiconductor device with a block of 8 LEDs. The output 9 of the control circuit 7 is connected to the input 10 of the LED unit 8. The inputs 11 and 12 of the control circuit 7 are connected to two terminals 2 of the board 1, and the input 13 of the LED block 8 is connected to the third terminal of the board 1.

The control circuit 7 (FIG. 3) contains a Schmidt trigger 14, resistors 15.16 and 17, a capacitor 18 and a diode 19.

Nribor works as follows.

Until the supply voltage to the inputs 11 and 13 of the device is supplied, the capacitor 18 is discharged and the voltage across it, corresponding to the supply voltage of the trigger 14, is zero. The output of the trigger 14 is in the closed state, and the block 8 of the LEDs is in the off state. But as the charge of the capacitor 18 through the block 8 of the LEDs, the diode 19 and the resistor 15, the voltage across the capacitor 18, and, therefore, the voltage of the trigger 14 is growing. At the same time, the voltage across the resistor 17 corresponding to the input control voltage of the trigger 14 also increases. When the voltage across the resistor 17 reaches the upper trigger threshold of the trigger 14, the latter switches to the open state and the LEDs of block 8 light up. From this moment, the capacitor 18 begins to discharge through the resistors 16 and 17 and the internal resistance of the trigger 14, while the voltage across the capacitor 18 and the resistor 17 decreases. When reaching the voltage across resistor 17 of the lower threshold

trigger 14, the latter again switches to the closed state, while the LEDs of block 8 are turned off, and the capacitor 18 starts charging again and the whole process of turning on / off the trigger 14 and block 8 of the LEDs is repeated. The frequency of this process is determined by the charge / discharge time of the capacitor 18 and depends on the values of the resistors 15.16 and 17 and the capacitor 18.

When you connect an external capacitor or resistor to the inputs 11 and 12 of the device, you can increase or decrease the on / off time of trigger 14 and block 8 of the LEDs. The authors:/ ,. M.I. Karpushin L.F. Snitkov
