Abstract

A desk lamp belongs to the field of illumination, and comprises a main lamp formed by a fluorescent lamp and a secondary lamp formed by an incandescent lamp, wherein the secondary lamp has adjustable light and shade states, and the power consumption of the dark state is about half of that of the bright state. The method is characterized in that: the circuit I, the incandescent lamp circuit II, the incandescent lamp and the diode series circuit III are electrically connected in sequence by the known ballast, the fluorescent lamp and the starter through the ingenious combination of the switches. The preferred embodiment is that the fluorescent lamp is H lamp, 8W straight tube fluorescent lamp, double D lamp, incandescent lamp is 10W, and the switch is two single-pole two-position (double control) switches. When the incandescent lamp is equipped with a detachable colored outer cover (17), it can also emit two different colored lights, its structure is simple, it saves electricity, and it is convenient for night activities.

Description

Master/slave three-state lamp

The utility model relates to lighting field, is a kind of a kind of desk lamp that not only can write but also can carry out nocturnalism.

At present, general family needs multiple light source, when wherein using fluorescent lighting as desk lamp when nocturnalism, adopt small-power H lamp mostly, small-power straight-pipe fluorescent lamp or two D lamp, wherein the power of H lamp is generally 11W, 9W, 7W, and the power of straight-pipe fluorescent lamp is 8W, during their illuminations, brightness is bigger, when the darker occasion of needs, often needs to increase other light fixtures." mini light " that Waja, Shanghai electrical apparatus factory produces; adopt 220V; the 10W incandescent lighting; the light fixture straight cutting and has removably coloured lampshade in supply socket, it is simple in structure; low price; to be " mini light " nursing the sick and during the baby, it is brighter to seem night, and power consumption its weak point.

The purpose of this utility model provides a kind of desk lamp, both can send fluorescent lamp than the light look, the incandescent lamp that can send two kinds of different brightness again is photochromic, when incandescent lamp is furnished with band color outer cover, also can send two kinds of colored light that power is different.

The purpose of this utility model is achieved in that fluorescent lamp and lampshade, lamp socket, flexible flexible pipe, ballast, lamp socket constitute the fluorescent lamp desk lamp, fluorescent lamp can be selected the H lamp for use, 8W straight-pipe fluorescent lamp or two D lamp, incandescent lamp bulb and lamp holder, switch are contained on the lamp socket, and fixing or removably coloured lampshade are housed on the bulb.By the combination of switch, constitute three circuit: it is by known ballast, fluorescent lamp, the starter circuit one that is electrically connected to form in proper order, and by the incandescent lamp circuit two that is electrically connected to form, incandescent lamp and diode are electrically connected in series forming circuit three.When circuit one led to, fluorescent lamp was bright, and when circuit two led to, incandescent lamp was bright, and during the circuit threeway, incandescent lamp is secretly bright.The three-circuit interlocking, perhaps circuit one is connected simultaneously with one of circuit two or circuit three.

The utility model relates to a desk lamp, can send the light of three kinds of brightness, both available fluorescent lamp is done brighter illumination, and an available again incandescent lamp is done two kinds of illuminations of light and shade, the power that dark state is consumed is about half of bright state institute consumed power, when selecting 10W for use, can obtain the power of about 5W, when being furnished with color cap as incandescent lamp, also can carry out bright, dark two kinds of color lightings, its circuit structure is simple, and power saving brings convenience to nocturnalism.

Below in conjunction with the embodiment accompanying drawing the utility model is further specified.

Fig. 1, Fig. 2, Fig. 3 are respectively the utility model first, second, third embodiment electrical schematic diagrams.

Two contacts (position) of the utmost point 2.3.KA of four button 1.KA among the figure in KA, KB, KF one pole two-position switch (double control switch) KC piano key switch K1, K2, K3, the K4 keyboard switch are two contacts (position) KD.KF switch 17. of the utmost point 15.16.KF of two contacts (position), 12. incandescent lamps, the 13. diode 14.KF of the utmost point 10.11.KB of the ballast 5.7. Filament of fluorescent lamp 6. starters 8. fluorescent lamp 9.KB incandescent lampshade that can fix or load and unload 4..

In Fig. 1, status lamp goes out shown in the diagram, when KA dials to (2), then KA(1), (2), ballast (4), filament (5), starter (6), filament (7), KB(10), (9) order is electrically connected, built-up circuit one, fluorescent lamp is bright.Then, KB dials to (11), then KB(9), (11), incandescent lamp (12), diode (13) order is electrically connected built-up circuit three.This moment, fluorescent lamp went out, and incandescent lamp is secretly bright.At this moment, stir KA again, perhaps initial disconnected state is stirred KB once, constitutes KA(1), (3) incandescent lamp (12), KB(11), (9) order is electrically connected built-up circuit two.This moment, incandescent lamp was bright.

In Fig. 2, K1, K2, the mutual interlocking of K3, K4, when K4 pressed, K1, K2, K3 broke, and lamp goes out.When K1 pressed, K1 was logical, and K2, K3, K4 break, forming circuit one, and fluorescent lamp is bright.When K2 pressed, K2 was logical, and K1, K3, K4 break, forming circuit two, and incandescent lamp is bright.When K3 pressed, K1, K2, K4 broke, and forming circuit three, incandescent lamp are secretly bright.According to the structure of keyboard switch, only can reach above purpose equally with three button K1, K2, K3, the initial state of K1, K2, K3 is disconnected state at this moment.As without keyboard switch, available other interlock type switches substitute.

In Fig. 3, when connecting KE, be electrically connected by KE, ballast (4), filament (5), starter (6), filament (7) order, forming circuit one, fluorescent lamp is bright.When KD connects, position according to KF, formation is by KD, KF(14), (16), incandescent lamp (12) order is electrically connected circuit two, this moment, incandescent lamp was bright, perhaps by KD, KF(14), (15), diode (13), incandescent lamp (12) order is electrically connected circuit three, this moment, incandescent lamp was secretly bright.When KE and KD connected simultaneously, circuit one and circuit two or circuit three can be connected simultaneously, and one of bright, dark two kinds of light of fluorescent lamp and incandescent lamp are lighted simultaneously.
