Embodiment 1

[0027] Embodiment 1: The miner's lamp with flashing light source of the present invention contains a battery, a main light source and an auxiliary light source. The battery is connected to the main light source and the auxiliary light source through a switch circuit. The switch circuit is controlled by a microprocessor, and the switch circuit contains control buttons. , microprocessor and switch control elements, and the control buttons are installed on the battery shell of the miner's lamp.

[0028] see figure 1 , is one of the schematic diagrams of the miner's lamp circuit with the flickering light source in this embodiment: the microprocessor adopts PIC12C508, the switch control element adopts a field effect transistor, the VCC port of PIC12C508 is connected to the power supply (i.e. the battery positive pole), and the VSS port of PIC12C508 is grounded (i.e. Battery negative pole), one I / O port GP1 of PIC12C508 is connected to the control button S1, the other end of the con...

Embodiment 2

[0042] Embodiment two: see figure 2 , the structure of this embodiment is basically the same as that of Embodiment 1, with one difference: wherein the switch control element adopts a power triode, and the control bases of the power transistors Q1 and Q2 are respectively connected to two microprocessors through current-limiting resistors R1 and R2. I / O output ports, the emitters of the power transistors Q1 and Q2 are connected to the negative pole of the battery, and the collectors are respectively connected to the positive pole of the battery through the main light source L1 and the auxiliary light source L2. The power triode can be replaced by a Darlington tube (composite tube).

Embodiment 3

[0043] Embodiment three: see image 3 The difference between this embodiment and the above-mentioned embodiments is that the microprocessor can use any chip in PIC10F200 / 202 / 204 / 205, and the switch control element can also use a power triode, or a field effect tube. The specific connection relationship is: the VCC port of the microprocessor is connected to the power supply, which is the positive pole of the battery, the VSS port is grounded, which is the negative pole of the battery, one I / O port GP1 of PIC10F2XX is connected to the control button S1, the other end of the control button S1 is grounded, and the two I / O ports of PIC10F2XX are connected to the ground. The / O output ports GP0 and GP2 are respectively connected to the trigger control ends of the two switch control elements, and the output ends of the two switch control elements are respectively connected in series with the main light source and the auxiliary light source and connected between the two poles of the b...

Abstract

The invention relates to a safety lamp, with flash light source. Wherein, the accumulator via switch circuit is connected to the main and auxiliary light sources; the switch circuit comprises control press-key, micro processor and a switch control element; one end of control press-key is connected to the I/O input port of micro processor; two I/O output ports of micro processor are connected to trigger control ports of two switch control element; said outputs of switch control elements are independently serially connected to the main and auxiliary light sources to be connected between two poles of accumulator. In the command condition or over the preset time, the safety lamp will automatically switch into flash condition of auxiliary light source; in special condition, it can prolong the light time, to prolong the rescue time. The invention has simple circuit, with wider application.

Description

1. Technical field: [0001] The invention relates to a mine lighting lamp, in particular to a miner's lamp with a flashing light source. 2. Background technology: [0002] The previous miner's lamps used a single light source for lighting. When the filament burned out, they could not be used. Only the miner's lamp or the light bulb could be replaced. However, changing the light bulb in the mine is prone to safety accidents and does not meet the safety regulations. You can only carry a spare miner's lamp. kind of hard. Ordinary light bulbs are easy to burn out, consume more electricity, use for a short time, and waste energy. Later, with the development of science and technology, alternative and more energy-saving new light sources gradually appeared. Among them, LED light-emitting tubes are commonly used, which have high brightness and save electricity. Light-emitting tubes are used at the same time, and now people have made LED light-emitting tubes with relatively high pow...
