Abstract

The utility model discloses a limited power lamp holder for an incandescent lamp. The utility model is characterized in that a capacitor is connected in series between an electrode and a binding post; a base and the lamp holder body are inserted and fixed with a clamp groove. The utility model has the advantages that the actual consumed power of a lamp bulb on the limiting power lamp holder can not be larger than the limited power of the limiting power lamp holder by 22% regardless of the rated power of the lamp bulb; the utility model is suitable for serving as the lamp holder in a public place to prevent the users from wasting electric energy by using a high-power light bulb; the voltage on the lamp bulb can be reduced for a certain amount due to the voltage dividing function of the capacitor in the lamp holder so the service life of the lamp bulb can be prolonged; the installation of the limited power lamp holder is easy.

Description

Limited power lamp base

The utility model relates to a kind of lamp socket that is used for illuminating lamp, particularly a kind of lamp socket of energy power-limiting.

The lamp socket of the incandescent lamp that generally can buy all is two kinds of socket type and screw types in the market, and these two kinds of lamp sockets can not play restriction to the power consumption of bulb, and the installation of lamp socket is also more loaded down with trivial details.

The purpose of this utility model is to provide a kind of restriction incandescent lamp power consumption and easy-to-install Limited power lamp base.

The utility model is finished with the following method, Limited power lamp base comprises lamp holder (1) and two binding posts (2) on it and two electrodes (3), capacitor (4) is housed in the middle of lamp holder (1), capacitor (4) is serially connected between electrode (3) and the binding post (2), lamp holder (1) is inserted on the mounting seat (5), and between lamp holder (1) and the mounting seat (5) fixedly is to be stuck in draw-in groove (7) internal fixation with the projection on its contact-making surface (6).Draw-in groove (7) is out that projection (6) is on the lateral wall of mounting seat (5) lower end on the madial wall of lamp holder (11) upper end.

The bulb of the utility model Limited power lamp base to using, no matter its rated power is much, the real power consumption of bulb can not surpass 22% of power that this lamp socket is limit, power that lamp socket is limit is determined by dress capacitor volume within it.When bulb power is equal to or less than this lamp socket and limits power, bulb can emit a brilliant light, when bulb power is limit power greater than lamp socket, bulb can only send dim light, when bulb power arrives to a certain degree greatly, bulb is not luminous substantially, simultaneously owing to be connected in series a capacitor on the inherent circuit of lamp socket.The power factor (PF) of improving electrical network is beneficial to, because the effect of capacitor, the voltage on the bulb descends to some extent, can prolong the useful life of bulb.When particularly all night using lamp in public places, when line voltage is higher at dead of night, more obvious to prolonging bulb life.Owing to be fixed by flexible card between lamp holder and the mounting seat, can be convenient to install in addition, this lamp socket is applicable to and is contained in the public place, can prevent effectively that the user from adorning big bulb waste electric energy.

Below in conjunction with accompanying drawing the utility model is described in further detail:

Fig. 1 is a longitudinal sectional view of the present utility model

Fig. 2 is the vertical view of lamp holder (1)

Fig. 3 is the A-A cutaway view of Fig. 2

Fig. 4 is the vertical view of mounting seat (5)

Fig. 5 is the B-B cutaway view of Fig. 4

As shown in Figure 1, lamp holder (1) is a screw socket, the electrode (3) of bulb being installed and being conducted electricity to bulb is housed in lamp holder, capacitor (4) is housed in the middle of lamp holder (1), capacitor (4) is insulated plate (8) and is pressed in the lamp holder, capacitor (4) is serially connected between electrode (3) and the binding post (2) through lead (9), and another electrode (3) connects binding post (2) through lead (9), constitutes to connect supply voltage after electric light (resistance) is connected in series capacitor (4) in circuit.On the upper end madial wall of lamp holder (1), have draw-in groove (7), as Fig. 2, shown in Figure 3, projection (6) is arranged on the lateral wall of mounting seat (5) lower end, as Fig. 4, shown in Figure 5, when being inserted into lamp holder (1) on the mounting seat (5), the projection (5) on the base (5) may be stuck in the draw-in groove (7) on the lamp holder (1), lamp holder (1) is fixed on the base (5), base has an installing hole on (5), and is earlier that base is fixing on the wall, inserts lamp holder then and gets final product.Take off also and be easy to, because of the sidewall of lamp holder (1) and base (5) all has certain elasticity, breach (10) on the mounting seat (5) can make wire clamp put in and be equipped with when installing, utilize the wire clamp location, can prevent that lamp socket from rotating when the mounting or dismounting bulb is stressed.

The principle of this lamp socket restriction bulb power consumption is the partial pressure properties that is connected on after utilizing capacitor and resistance (bulb) being connected on the AC power, voltage on the bulb (being resistance) becomes big (being resistance decreasing) with bulb power and diminishes, thereby reaches the purpose of restriction bulb electrical power.

Claims (2)

1, a kind of Limited power lamp base, it comprises lamp holder (1) and two binding posts (2) on it and two electrodes (3), it is characterized in that capacitor (4) being housed in the middle of the lamp holder (1), capacitor (4) is serially connected between electrode (3) and the binding post (2), it between the lamp holder (1) and mounting seat (5) fixedly is to be stuck in draw-in groove (7) internal fixation with the projection on its contact-making surface (6) that lamp holder (1) is inserted on the mounting seat (5).

2,, it is characterized in that draw-in groove (7) is out that projection (6) is on the lateral wall of mounting seat (5) lower end on the madial wall of lamp holder (11) upper end according to the described lamp socket of claim 1.
