Abstract
A near-infrared light source device for prolonging, it comprises base plate plate, power supply, switch, light source, inductance, coil, electric capacity, contact and some wires composition, when the startup of switch closed i.e. near infrared device, switch, power supply, light source, inductance and coil will form a loop, capacitor charging simultaneously, loop is had just to have electric current to flow through light source, because there being the existence of inductance, electric current can not become large quickly, meeting change is slowly large, when greatly to a certain extent, the magnetic that coil produces will attract contact to carry out adhesive, mask the effect of inductance, to save electric energy, and then reduction starting current, protection light source, when the switch is opened, owing to not had power supply, capacitor discharge, the electric current flowing through light source would not break quickly, thus play the effect of protection light source.
Description
Technical field
The utility model provides a kind of near-infrared light source device for prolonging, belongs to tobacco business tobacco leaf chemical score and detects technical field of automation.
Background technology
In current tobacco leaf chemical score detection field, it has been a standard configuration that near infrared device detects, near infrared device sends specific light beam, be irradiated on tobacco leaf, the chemical score of tobacco leaf is determined by detecting the spectrum received, because device limit, the energy requirement of the light beam sent is very strong, and the supply voltage of light source only has 12V, just very large by the electric current of light source luminescent device like this, in the process of switch near infrared device, due to unexpected incoming call and power-off, and logical be all big current, very large to the damage of the luminescent device of light source, the life-span of reducing light source that can be serious.
Summary of the invention
In order to solve current near-infrared light source because of in switching on and shutting down process, big current can reduce the situation of light source life, and the utility model provides a kind of near-infrared light source device for prolonging, and it can reduce start with shutdown process, the change of electric current, to the damage of light source, improves the life-span of near infrared device.
The technical scheme that the utility model provides is: provide a device for prolonging, it comprises base plate plate, power supply, switch, light source, inductance, coil, electric capacity, contact and some wires composition, power supply, switch, light source, inductance, coil, electric capacity, contact are fixed on base plate, coil and contact form one and combine, contact and inductance in parallel, circuit after parallel connection integrally with light source, coils connected in series, circuit after series connection integrally with Capacitance parallel connection, circuit after parallel connection integrally with switch and power sources in series, form a loop.When the startup of switch closed i.e. near infrared device, switch, power supply, light source, inductance and coil will form a loop, capacitor charging simultaneously, loop is had just to have electric current to flow through light source, because there being the existence of inductance, electric current can not become large quickly, meeting change is slowly large, when greatly to a certain extent, the magnetic that coil produces will attract contact to carry out adhesive, mask the effect of inductance, to save electric energy, and then reduction starting current, protection light source, when the switch is opened, owing to not had power supply, capacitor discharge, the electric current flowing through light source would not break quickly, thus play the effect of protection light source.
The beneficial effects of the utility model are: the life-span that can extend light source, improve equipment life, save the production cost of enterprise, thus increase the benefit.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
In figure, 1 be power supply, 2 for switch, 3 be inductance, 4 be contact, 5 be coil, 6 be electric capacity, 7 be light source.
Embodiment
Get one piece of plank, material is not limit, and prepares power supply, switch, inductance, contact, coil, electric capacity, light source and some wires, connects by the circuit diagram shown in Fig. 1.
