Description

A kind of lighting device

Technical field

The utility model belongs to field of illuminating device, more particularly to a kind of lighting device.

Background technology

Currently, double control switch panel is widely used to bedroom due to its convenience in fitting up.Such as：Same one A lamp, you are not only intended to control in this place, also want to, in another place control, reform into two switch panels in this way All want while controlling this lamp, this when, you will use double control switch.Although double control switch has its convenience, But he can only control a lamp, when rest in bed, people often tend to using the softer desk lamp of light, and Non-illumination lamp just produces inconvenience at this moment.

Therefore, these problems are based on, provide it is a kind of be automatically closed when opening desk lamp headlamp, and headlamp has self-locking work( The lighting device of energy has important practical significance.

Invention content

The utility model provides one kind for technical problem present in solution known technology and works as opening desk lamp headlamp certainly It is dynamic to close, and headlamp has the lighting device of self-locking function.

The utility model is adopted the technical scheme that solve technical problem present in known technology：

A kind of lighting device, the lighting device include headlamp, desk lamp, the first relay and the second relay, described Desk lamp connect with single lock switch, the first relay, the headlamp switchs with double-gate, a pair of of normally-closed contact of the first relay, A pair of of normally-closed contact of second relay is connected, and a pair of of normally opened contact of first relay and a pair of the second relay are often After opening contact shunt, connect with the second relay and double-gate switch.

The utility model has the advantages and positive effects of：

The utility model is automatically closed when opening desk lamp headlamp, ensures that desk lamp will not light simultaneously with headlamp, into one Step, headlamp has self-locking function, and when desk lamp is closed, headlamp will not be bright in the state that double-gate switch is in closure It rises.

Description of the drawings

The technical solution of the utility model is described in further detail below with reference to drawings and examples, still It should be known that these attached drawings only design for task of explanation, therefore not as the restriction of the scope of the utility model.In addition, Unless otherwise indicated, these attached drawings are meant only to conceptually illustrate structure construction described herein, without to carry out to scale It draws.

Fig. 1 is the structural schematic diagram of the utility model.

In figure：

1, headlamp；2, desk lamp；3, the first relay；4, the second relay；5, single lock switch；6, double-gate switchs；7, A pair of of normally-closed contact of one relay；8, a pair of of normally-closed contact of the second relay；9, a pair of of normally opened contact of the first relay； 10, a pair of of normally opened contact of the second relay.

Specific implementation mode

Firstly, it is necessary to explanation, below by by way of example come illustrate the utility model lighting device tool Body structure, features and advantages etc., however what all descriptions were intended merely to illustrate, and should not be construed as to this practicality Novel formation any restrictions.In addition, the arbitrary single technical characteristic for being described by or implying in each embodiment mentioned by this paper, Or shown or implicit arbitrary single technical characteristic in the drawings, it still can be in these technical characteristics (or its equivalent) Between continue it is arbitrary combination or delete, to obtain may not herein directly refer to the utility model it is more its His embodiment.In addition, for the sake of simplifying drawing, same or like technical characteristic in the same figure may be only at one It is indicated.

It will be understood that, when component ' attach ' to another component when it is said that, it can be directly connected to another component or There may be intermediate members.On the contrary, when component " being directly connected to " being arrived another component when it is said that, then it represents that middle part is not present Part.

Fig. 1 gives the structural schematic diagram of the utility model, illustrates the utility model with regard to Fig. 1 below.

For that can further appreciate that the invention, features and effects of the utility model, the following examples are hereby given, and coordinates Detailed description are as follows for attached drawing：

A kind of lighting device, the lighting device include headlamp 1, desk lamp 2, the first relay 3 and the second relay 4, The desk lamp 2 is connected with single lock switch 5, the first relay 3, a pair of the headlamp 1 and double-gate switch 6, the first relay Normally-closed contact 7, the second relay a pair of of normally-closed contact 8 connect, a pair of of normally opened contact 9 and second of first relay after After 10 parallel connection of a pair of of normally opened contact of electric appliance, connect with the second relay 4 and double-gate switch 6.

As an example, in the present invention, as indoor nobody, as shown in Figure of description 1, desk lamp 2 and illumination Lamp 1 is in off-state.After people gets in, double-gate switch 6 is set to be closed, due to the first relay 3 and the second relay 4 It is in off-position, therefore, a pair of of normally-closed contact 7 of the first relay and a pair of of normally-closed contact 8 of the second relay are located In closed state, headlamp 1 lights, and when needing rest, needs to close headlamp 1, bright desk lamp 2 is put, as long as by single lock switch 5 Closure.At this point, the first relay 3 is powered, a pair of of normally-closed contact 7 of the first relay disconnects, and headlamp 1 extinguishes, meanwhile, A pair of of normally opened contact 9 of first relay is closed, since double-gate switch 6 is in closed state at this time, the second relay 4 It is powered, a pair of of normally opened contact 10 of the second relay is closed, and the second relay 4 is made to complete self-locking.It needs during sleep, to disconnect single lock Switch 5 closes desk lamp 2.At this point, the first relay 3 is in off-position, but since the second relay 4 is in self-locking shape State, at this point, a pair of of normally-closed contact 8 of the second relay is off.After waking up, when withdrawing from a room, by double-gate switch 6 with Ment is opened, and the self-locking state of the second relay 4 is released.

The utility model is automatically closed when opening 2 headlamp 1 of desk lamp, ensures that desk lamp 2 will not light simultaneously with headlamp 1, Further, headlamp 1 has self-locking function, and when desk lamp 2 is closed, headlamp 1 is in the state that double-gate switch 6 is in and is closed It will not light.

In conclusion the utility model can provide it is a kind of be automatically closed when opening desk lamp headlamp, and headlamp have from The lighting device of lock function.

The utility model is described in detail in above example, but the content is only the preferable reality of the utility model Example is applied, should not be considered as limiting the scope of the present invention.Equalization made according to the scope of application of this utility model Variation and improvement etc., should all still belong within the patent covering scope of the utility model.
