Abstract
The utility model relates to a lamp seat which comprises a base casing, a cover plate which is installed on the base casing and an indicating lamp which is installed on the base casing and is connected with a control circuit which is positioned in the base casing. In the utility model, the control circuit comprises a rectification circuit which is positioned on an electronic circuit board and two switching transistors which are connected with the rectification circuit in parallel and are connected with a collecting electrode in series by an emitter; the indicating lamp is connected with a collecting electrode and an emitter of one of the switching transistors in parallel after being connected with a resistor in series. Because the lamp seat is provided with a light emitting indicating lamp which is controlled by an electronic transformer control circuit, when a quartz lamp cup on a lamp quenches, the utility model indicates that the quartz lamp cup has a need for changing when the indicating lamp is still bright; when the quartz lamp cup and the indicating lamp are both not bright, the utility model indicates that the electronic transformer in the base appears problems. Failures of lamps can be conveniently displayed according to the indicating lamp which is installed on the lamp seat adds aesthetic feeling for the lamp seat at the first time.
Description
Technical field
The utility model relates to a kind of lamp socket, the lamp socket of particularly a kind of Track light or ceiling light.
Background technology
At present, people because quartz lamp cup has certain useful life, after use a period of time, the phenomenon that quartz lamp cup is burnt out often occurs when using Track light or ceiling light.The reason that quartz lamp cup does not work has several situations, is burnt out such as quartz lamp cup, and the connecting line in the lamp socket breaks down, and perhaps the electronic transformer in the lamp socket has situations such as problem.Because it is very inconvenient that Track light or ceiling light overhead than higher, are checked one by one.In addition, Track light or ceiling light lamp socket outward appearance seem to seem more single, lack aesthetic feeling.At above these problems, people are badly in need of wanting a kind of substitute products to solve.
Summary of the invention
The purpose of this utility model provides a kind of convenient fault of judging lamp, and rakish lamp socket.
The utility model is achieved through the following technical solutions above-mentioned purpose.
A kind of lamp socket comprises base shell, is installed in the cover plate on the base shell, it is characterized in that: indicator light is installed on base shell, and indicator light is electrically connected with the control circuit that is positioned at base shell.
Described control circuit comprises the rectification circuit that is positioned on the electronic circuit board, and with two switch triodes that rectification circuit is connected in parallel, two switch triodes are connected in series by emitter and collector electrode; After being connected in series, indicator light and a resistance is connected in parallel on the collector electrode and emitter of a switch triode.
Described indicator light is the LED light-emitting diode
The utility model has the following advantages compared to existing technology.
Because luminous indicating lamp is installed on lamp socket, luminous indicating lamp is controlled by the electronic transformer control circuit.When the quartz lamp cup on the lamp does not work, if indicator light light yellow also shows that then needs change quartz lamp cup; If quartz lamp cup and indicator light all do not work, show that then the electronic transformer in the base goes wrong.So just can demonstrate the fault of lamp easily according to indicator light.The luminous indicating lamp of installing on the lamp socket has also increased a kind of aesthetic feeling to lamp socket simultaneously.
Description of drawings
Fig. 1 is the longitudinal sectional drawing of lamp socket installation diagram described in the utility model;
Fig. 2 is the control circuit figure of luminous indicating lamp described in the utility model;
Fig. 3 is that the utility model luminous indicating lamp is installed in the user mode figure on the lamp.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1, indicator light 2 is installed on the base shell 1 of lamp socket, and indicator light 2 can be the LED light-emitting diode, can also be emitting bulb, and can send colors such as blue light or ruddiness, green glow, mainly is to satisfy people's use habit.Indicator light 2 is fixed on the circuit board 3, is distributed with emission control circuit as shown in Figure 2 on the circuit board 3.Circuit board 3 can be installed in the shell 1 by screw, also can by cover plate 4 roof pressures in the shell 1 on the electronic device on the circuit board 3 and the cylinder by securing cover plate 4 carry out the left-right and front-back location positioning, thereby circuit board 4 is fixed in the shell 1.Emission control circuit as shown in Figure 2, mainly form by rectification circuit 5, switch triode 6, indicator light 2, rectification circuit 5 links to each other with power supply, two switch triodes 6 are connected in the output of rectification circuit 5 in parallel, two switch triodes 6 are connected in series by emitter and collector electrode, are connected in parallel on the collector electrode and emitter of a switch triode 6 after indicator light 4 and a resistance are connected in series.The rectification of power supply by rectification circuit 5, and make the luminous of indicator light 4 with ending to control by two switches, two utmost points, 6 pipe alternate conduction.Fig. 3 is that indicator light 4 is installed in the user mode on the lamp socket.The utility model provides convenience for people use lamp, particularly when changing quartz lamp cup, can avoid unnecessary trouble.In addition, indicator light 4 has also increased a kind of aesthetic feeling to lamp socket.
