Abstract

The utility model discloses a touch-actuated stepless light adjustable desk lamp which improves the existing desk lamp, belonging to the daily illuminating device. The desk lamp is provided with an induction type on-off circuit which picks up the induction of the human body and a dimmer circuit and is not provided with any mechanical moving part. So long as any part of the human body contacts any position of the lamp body, and the on-off command and the modulating light command are executed according to the length of the contact time, so the use is very convenient. Because two resistances with high resistance value are connected in series between a touch polar plate and the circuits, and the lamp body is insulating, so the user can not be shocked by the electricity.

Description

Touch-actuated stepless light adjustable desk lamp

The utility model is the improvement to existing desk lamp, is a kind of daily lighting device.

According to information, adopt the light adjusting circuit of large scale integrated circuit assembling, recently begun to cause people's interest, the desk lamp made from this light adjusting circuit, in use, a GPRS human body contact touches the short length of time of pole plate, and circuit just can be carried out logical one disconnected and instruction with an automatic light meter.The advantage of this desk lamp is no any mechanical movable part, operates also more convenient.Its weak point is, touch pole plate with definite shape and size, be difficult to be applicable to fully on different, the desk lamp that varies in size with design, particularly for not having the lamp body of directivity, as garden shape porcelain vase, be installed in lamp body inside owing to touch pole plate, the outside is beyond recognition, so that be difficult to accurate touch when using, especially in night, turn on light.

As long as the purpose of this utility model provides a kind of the touch stepless dimming desk lamp that just can execute instruction in any position of human body contact lamp body.

The utility model is so to realize, at the lamp body inwall made from pottery, glass or plastics, coated has one deck conducting film to connect with circuit as touching pole plate.

Because in fact touch pole plate of the present utility model spreads all over the whole or most of lamp body inwall, so need only any position of any part contact lamp body of human body when using, the induced signal of human body is promptly picked up by circuit and begins to carry out control command, therefore uses very convenient.Be logical severed finger order when the touch time is 50～400ms, the touch time is the light modulation instruction during greater than 400ms, and light will begin from the minimum brightness to the high-high brightness this moment, if continue to touch, then multiple by high-high brightness to minimum brightness, continuous light tuning so repeatedly.A light modulation cycle is 8 seconds.When light is transferred to the required brightness of user, hand is left lamp body, light just remains on this brightness illumination, and even turn off the light, the lamplight brightness of this moment etc. still is stored in the memory circuit, and when connecting once more, this brightness is promptly reproduced automatically.

In sum as can be known, the utility model not only is suitable for child, the sick and wounded especially and the handicapped person uses, can use also that various handicrafts make that art appreciation and practical value have concurrently both can be simple and unsophisticated tasteful and refined also can be the luxurious desk lamp of modern school.

Concrete structure of the present utility model is by following embodiment and description of drawings thereof.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is a circuit diagram of the present utility model.

As shown in Figure 1, porcelain vase be lamp body (7) inwall equably coated have one deck conducting film promptly to touch pole plate (5), (1) is power line, (2) be tie, (3) are cored screw, and (4) are packing ring, (6) be nut, (8) are lamp socket, and (9) are lampshade.

Each component parameters of circuit and model touch pole plate (5) as shown in Figure 2 through R ₄R ₅Be connected to the 5th pin of integrated circuit LS7232, R ₄, R ₅Resistance value be 4.7M Ω respectively, the resistance that high value like this arranged is added ceramic insulation as touching the isolation resistance of pole plate (5) with circuit, can protect the danger that the user does not have electric shock.

Claims

1, a kind of touch stepless dimming desk lamp that is used for normal lighting is made up of lamp body [7], lamp socket [8], lampshade [9], power line [1] and circuit, it is characterized in that the inwall coated of lamp body [7] has one deck conducting film promptly to touch pole plate [5].

2,, it is characterized in that the material of lamp body (7) is pottery, glass or plastics by the described lamp dimmer of claim 1.
