Abstract
The utility model relates to a rectifier diode group double-control mine lighting circuit. For saving power sources, after workers withdraw from a mine laneway, lighting equipment of the mine laneway needs to be switched off, however, if the lighting equipment is directly switched off, the workers need to walk to another section of mine laneway under the condition of no lighting. A light source EL is arranged in the circuit disclosed by the utility model; both sides of the light source EL are respectively connected in series with one parallel diode group which is reversely arranged; switches are connected in series between the two groups of parallel diode groups and the light source EL; the switches are double-throw switches; and two contacts of the double-throw switches are respectively connected onto two diodes in each parallel diode group. According to the utility model, the lighting equipment can be controlled in the mine laneway; the lighting equipment can also be controlled in the withdrawing process in a centralized mode; and not only are the power sources effectively saved, but also the lighting condition on the withdrawing path of the workers cannot be influenced.
Description
Technical field
The utility model relates to a kind of mine lighting circuit, is specifically related to the two control mine lighting circuits of a kind of rectifier diode group.
Background technology
The mine laneway illumination is the lifeline of assurance mine normal production, also is one of major measure of mine safety production, still owing to the environment and use present situation of mine laneway, causes mine laneway to throw light on and has the inconvenience part.For saving electric power resource, the staff need turn off the lighting apparatus of this mine laneway, but directly turn off after withdrawing from from mine laneway, and the staff just must not have to go to another section mine laneway under the situation of lighting condition.
Summary of the invention
The purpose of the utility model provides a kind of two control mine lighting circuits of rectifier diode group that can control the lighting apparatus switch in two places.
The technical scheme that the utility model adopted is:
The two control mine lighting circuits of a kind of rectifier diode group are provided with light source EL, it is characterized in that:
The diode group that described light source EL respectively connects both sides one group of parallel connection and oppositely is provided with;
All be in series with switch between described two groups of parallel diode groups and the light source EL.
Described switch is double-throw formula switch, and two electric shocks of double-throw formula switch are connected in respectively on two diodes in the parallel diode group.
Described diode is rectifier diode.
The utlity model has following advantage:
The two control mine lighting circuits of the described rectifier diode group of the utility model can be at mine laneway inner control lighting apparatus; Also concentrated area control lighting apparatus can withdrawn; Not only effectively practice thrift electric power resource, also can not influence the lighting condition on staff's evacuation path.
Description of drawings
Fig. 1 is the circuit diagram of the utility model.
Embodiment
Below in conjunction with embodiment the utility model is carried out detailed explanation.
The two control mine lighting circuits of the described a kind of rectifier diode group of the utility model are provided with light source EL, the diode group that light source EL respectively connects both sides one group of parallel connection and oppositely is provided with; Diode is rectifier diode.All be in series with switch between two groups of parallel diode groups and the light source EL.Switch is double-throw formula switch, and two electric shocks of double-throw formula switch are connected in respectively on two diodes in the parallel diode group.Because the undertension 220V that is applied on the light source EL, but 0.45 times of supply voltage under the situation that lighting condition is had relatively high expectations, needs the power of primary source is strengthened, and when needing 100W light source condition, must adopt the light source of 200W.
Claims (3)
