Abstract
The utility model relates to a whole-weather, automatic lighting device used for sighting telescope. The return circuit formed by the connection of a solar battery, a unilateral diode and a rechargeable cell is connected with a photoresistor, a parallel resistance and an LED in series. Adopted the joint use of the solar battery and the rechargeable cell, the utility model is suitable for whole-weather use without switch, and the brightness is automatically adjusted. The solar battery is used to work in daytime without switch and the long lifetime of continuous use can be reached to more than 10 years. The brightness of the luminotron can be automatically adjusted according to the illumination of the sunlight, and the sighting reaction rate are greatly enhanced.
Description
Technical field
The utility model relates to the lighting device that a kind of gun sight is used, especially can be round-the-clock, the device of automatic illumination.
Background technology
The gun sight lighting system all adopts source battery power supply (button cell CR2032 LITHIUM CELL accounts for more than 95%) on the international market at present.Its shortcoming one will turn on the power switch earlier when being to use, and regulator potentiometer is to select brightness again, and the aiming reaction is too slow, and it two is batteries useful life short (using continuously about 72 hours), and reliability is low.
The utility model content
The purpose of this utility model provides and a kind ofly is made of many power supplys, and that can regulate brightness automatically is used for that gun sight is round-the-clock, the device of automatic illumination.
The utility model is achieved in that on the loop that constitutes being connected by solar cell, unilateral diode, rechargeable battery, is connected with the series loop that is made of photo resistance, parallel resistance, light-emitting diode.
This patent adopts solar cell and rechargeable battery to unite use, is fit to round-the-clock use, need not switch, automatic brightness adjustment.Do not need switch when utilize solar cell working daytime, use its life-span can reach more than 10 years continuously, and can regulate the brightness of luminous tube automatically, improved the aiming reaction speed greatly according to the intensity of illumination of sunlight.When illumination is more weak, utilize the rechargeable battery power supply, utilize photo resistance to regulate brightness automatically.When its electric energy is low, can utilize daytime solar cell to charge automatically, high performance rechargeable battery (as the ML2032) more than 700 times that can charge repeatedly normally uses in 5 years and need not change battery.Unilateral diode guarantees that electric current does not cause loss by solar cell mouth stream, and parallel resistance guarantees that illumination has small amount of current to flow through when very weak and makes the sustainable work of light-emitting diode.Like this, both improved pointing velocity, improved useful life again.
Description of drawings
Accompanying drawing is the utility model electrical schematic diagram.
As shown in the figure, the utility model is achieved in that on the loop that constitutes being connected by solar cell, unilateral diode, rechargeable battery, is connected with the series loop that is made of photo resistance, parallel resistance, light-emitting diode.
Embodiment
Embodiment is as follows: the positive pole of solar cell 2 links to each other with the positive pole of diode 1, and the negative pole of diode 1 links to each other with the positive pole of rechargeable battery 3, and the negative pole of solar cell 2 links to each other with the negative pole of rechargeable battery 3; Be parallel with the series loop (5,6) that photo resistance 5, light-emitting diode 6 constitute on the negative pole of the negative pole of diode 1 and rechargeable battery 3, photo resistance 5 two ends are parallel with parallel resistance 4.
Claims (2)
1, a kind ofly is used for that gun sight is round-the-clock, the device of automatic illumination, on the loop that it is characterized in that constituting, be connected with the series loop that constitutes by photo resistance, parallel resistance, light-emitting diode connecting by solar cell, unilateral diode, rechargeable battery.
2, according to claim 1ly be used for that gun sight is round-the-clock, the device of automatic illumination, the positive pole that it is characterized in that solar cell (2) links to each other with the positive pole of diode (1), the negative pole of diode (1) links to each other with the positive pole of rechargeable battery (3), the negative pole of solar cell (2) links to each other with the negative pole of rechargeable battery (3), on the negative pole of the negative pole of diode (1) and rechargeable battery (3), be parallel with the series loop (5 that photo resistance (5), light-emitting diode (6) constitute, 6), photo resistance 5 two ends are parallel with parallel resistance (4).
