Abstract
The utility model relates to a desk lamp, in particular to an intelligent desk lamp controlled by an infrared signal and an optical signal. The desk lamp mainly comprises an office chair and a desk lamp, wherein the office chair comprises an infrared transmitting part; and a desk lamp holder comprises an infrared receiving part, a light sensing part and a 555 control part. When people sit on the office chair, an upper conducting strip in at least an elastic switch will be contacted with two lower conducting strips, the infrared transmitting system sends infrared and the infrared receiving diode receives the infrared and is connected to the fourth pin of NE555. The photoresistance will change according to change of light intensity, thus causing level changes of the second and sixth pins of NE555. The output end can be controlled by the fourth, second and sixth pins of NE555, thus controlling the switch of the desk lamp. The desk lamp has simple circuit, is safe and reliable and can bring funs to lives of people.
Description
Technical field
The utility model relates to the system that a kind of office chair and desk lamp constitutes, particularly a kind of desk lamp of being controlled by infrared signal and light signal.
Background technology
Along with the continuous development of society's science and technology, we are also increasingly high to the requirement of quality of life, and wherein, intellectuality just can bring convenience for people's life and enjoyment.In daily life, most desk lamp all is a hand switch, and trouble like this will seem.
Summary of the invention
The purpose of the utility model mainly provides a kind ofly brings enjoyment and intelligent easily desk lamp to people.Native system mainly is made up of office chair and desk lamp, and the infrared emission system is arranged in the chair, and its function mainly is can send infrared signal after the people takes, and just can not send infrared signal again after standing up.Desk lamp partly is made up of infrared receiving unit, light sensation part and control part branch.
The intelligent desk lamp of the utility model is characterized in that: desk lamp is to come common control by the power of light and these two parts of infrared signal, and when light intensity was higher than etalon optical power, desk lamp was can be not bright; When light intensity is lower than etalon optical power, and must receive infrared signal the time, desk lamp just can be bright, and these two conditions are indispensable.

Embodiment
As shown in Figure 1, the utility model mainly is to be made up of office chair and desk lamp, wherein includes the infrared part on the office chair, includes infrared ray receiving unit, light sensation part and 555 control sections on the lamp socket of desk lamp.
On office chair, most important parts is exactly the infrared transmitter of being controlled by elastic switch.Elastic switch mainly is made up of elastomeric plastic film and guide card, and its structure is as shown in Figure 2.Adopted the elastic switch of 6 parallel connections in the infrared emission circuit of the utility model, as long as an elastic switch closure is arranged, circuit will conducting, and the distribution of its switch on seat is as shown in Figure 3, and such purpose is for better conducting of circuit.After the people took, the guide card of top will contact with two guide cards of bottom in the elastic switch, and circuit will conducting, after the people stands up since the guide card of elastic reaction top will with two guide cards of bottom separately, circuit will break off.RF transmitter mainly is to be made up of a NE555 time-base circuit, and it is connected into the no steady operation pattern of frequency adjustable, when the elastic switch closure, and the circuit starting of oscillation, oscillating current drives two infrarede emitting diode D1, D2 by the output of 3 pin and outwards launches infrared ray.The purpose that adopts two light-emitting diodes is to increase infrared light intensity and emission radius, helps receiver and accepts.Its circuit theory diagrams are as shown in Figure 4.
Shoulder part after the design height of the backrest of office chair is taken than the people at least is high, can guarantee that like this infrared ray can not blocked by the people.
On the lamp socket of desk lamp, consist predominantly of infrared ray receiving unit, light sensation part and 555 control sections, as shown in Figure 5.Infrared receiving unit is by infrared receiver diode; And three high-gain inverting amplifier compositions that inverter constitutes; When infrared receiving diode VL2 receives the infrared ray that the infrared emission part is launched; Can produce low level signal at the VL2 two ends, after anti-phase was amplified, 4 pin of NE555 became high level.
The light sensation part mainly is to be controlled by photo resistance.When daytime, extraneous available light was stronger, photo resistance RL presented low resistance, and 2,6 bipods of NE555 control circuit are high level, greater than 2/3VDD, are in reset mode.Output 3 pin output low levels, relay K is failure to actuate, and desk lamp EL does not work.RL lost illumination and presented high resistance evening, made trigger end 2 pin of NE555 be in low level, less than 1/3VDD; Add and receive infrared ray, promptly under the situation of 4 pin high level, output 3 pin will be exported high level; Relay K gets electric adhesive, and its make contact K-1 is closed, desk lamp EL electrified light emitting.The resistance of regulator potentiometer RP1 can regulating circuit light-operated sensitivity, make circuit relay K under the environment that needs are turned on light get electric adhesive.R6 and C6 can form disturbing pulse and absorb circuit, can prevent the operate as normal because of of short duration light (thunderous lighting light, vehicle light etc.) interfered circuit.Because this schmitt trigger that the NE555 circuit constitutes has the hysteresis voltage of 1/3VDD, thereby can avoid relay to cause frequently beating of light-operated critical point place that desk lamp EL's is glittering.When installing, photo resistance should avoid the irradiation of desk lamp EL self light.
The power supply of infrared emission part adopts powered battery, and the power supply of 6V is provided.Circuit power on the Bulb holder of table lamp adopts transformer T step-down, and four diodes constitute bridge rectifier D, the LM7812 three-terminal voltage-stabilizing, and C3, C4 filtering get direct current 12V operating voltage.
In the time of daytime, no matter whether the people is sitting on the office chair, desk lamp can be not bright.In the time of evening, after the people was sitting on the office chair, the guide card of top will contact with two guide cards of bottom in the elastic switch, and desk lamp will be light automatically; When nobody sat, desk lamp can be not bright yet.
Claims (4)
1. the intelligent desk lamp of the utility model, it is characterized in that: it is made up of office chair and desk lamp two parts, wherein includes the infrared part on the office chair, includes infrared ray receiving unit, light sensation part and 555 control sections on the lamp socket of desk lamp.
2. intelligent desk lamp as claimed in claim 1 is characterized in that: desk lamp is to be controlled jointly by infrared ray and two factors of light intensity.
3. intelligent desk lamp as claimed in claim 1 is characterized in that: what the switch of infrared emission system adopted is elastomeric elastic switch.
