Abstract
The utility model relates to a desk lamp of steerable illuminance belongs to lamps and lanterns and makes technical field. The device consists of a light intensity control circuit, a working circuit and a power supply circuit, and all the circuits are electrically connected. The illuminance control circuit consists of a photoresistor, an NE555 time base circuit, a resistor, an illuminance range adjusting resistor and a relay, and all the elements are electrically connected. The utility model discloses a novel desk lamp based on change of ambient light illuminance, can be automatic when ambient light is less than certain limit illuminance open the desk lamp, the desk lamp can be extinguish automatically when the sum of the illuminance of environment and desk lamp is higher than certain upper limit illuminance, sends the chimes of doom simultaneously, reminds people to adjust.
Description
Technical field
The utility model relates to a kind of desk lamp, belongs to light fixture manufacturing technology field.
Background technology
In the life, people always like laying out a desk lamp on desk, not only in order to decorate, also for convenience simultaneously.But the variation of ambient light is forgotten in excessive the concentrating on study and read of people spirit sometimes, can not in time open desk lamp during deepening gradually when light, if for a long time like this, may cause myopia.Simultaneously,, will cause local light pollution, can make retina and iris all be subjected to the different infringement of degree and neurasthenic symptom occurs, serious harm people's health if light is too strong.And traditional desk lamp just comes pre-myopia prevention from people's sitting posture aspect, has ignored illuminance.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of desk lamp of may command illuminance of simple in structure, easy to use, health care eye vision.
The utility model is made up of illuminance control assembly, operating circuit parts and power circuit parts, and carries out electrical connection between each parts.
Described illuminance control circuit adjusts resistance by photo resistance, NE555 time-base circuit, resistance, illuminance scope and relay is formed, and each element is carried out and is electrically connected.
Described operating circuit parts are made up of fluorescent tube, resistance and relay, and each element is carried out and is electrically connected.
Described power circuit parts are made up of bidirectional switch, power transformation device, electric capacity, electrical appliance module 7806 and diode, and each components and parts is carried out and is electrically connected.
The utility model is based on a kind of novel desk lamp of the variation of ambient light illumination, when being lower than a certain lower limit illuminance, ambient light can open desk lamp automatically, when being higher than a certain upper limit illuminance, the illuminance sum of environment and desk lamp can extinguish desk lamp automatically, send chimes of doom simultaneously, reminds people is regulated.
Description of drawings
Accompanying drawing 1 is a structured flowchart of the present utility model;
Accompanying drawing 2 is illuminance control circuit figure of the present utility model;
Accompanying drawing 3 is a working circuit diagram of the present utility model;
Accompanying drawing 4 is a power circuit diagram of the present utility model.
Wherein, 1, the illuminance control assembly, 2, the operating circuit parts, 3, power circuit parts.
Embodiment
Embodiment: structure is made up of illuminance control assembly 1, operating circuit parts 2 and power circuit parts 3 as shown in Figure 1, and carries out electrical connection between each parts.
Structure is made up of photo resistance, NE555 time base module, resistance, illuminance scope adjustment resistance and relay as shown in Figure 2, and each element is carried out and is electrically connected.RG1, RP1 detect resistance for upper limit illuminance, and RG2, RP2 detect resistance for the lower limit illuminance.Prescribe a time limit when illuminance is lower than down, TRI pin current potential is lower than 1/3V, OUT pin output high level, and the relay adhesive, LED2 is bright, begins to start operating circuit; Prescribe a time limit when illuminance is higher than, THR pin current potential is higher than 2/3V, OUT pin output low level, and relay discharges, and LED is bright, disconnects operating circuit.
Structure is made up of fluorescent tube, resistance and relay as shown in Figure 3, and each element is carried out and is electrically connected.Resistance is the resistance of adjustable lighting tube brightness, and applied voltage is AC220V.
Structure is made up of bidirectional switch, power transformation device, electric capacity, electrical appliance module 7806 and diode as shown in Figure 4, and each components and parts is carried out and is electrically connected.The 6V voltage that is provided is used for the illuminance control circuit.
During use, at first adjust upper limit illuminance, RG1 is placed desired upper limit illuminance environment (using the light luminance detection), after spending a few minutes, regulate RP1 to LED1 just luminous till, the repeatedly accent several times more, can be earlier with the TRI pin with short circuit once, make OUT pin output high level, be convenient to observe rollover states like this.Adjust the lower limit illuminance then, process is the same, regulates RP2 and makes LED2 bright, also will be repeatedly several times, can be earlier with THR pin and power supply V short circuit once, make OUT pin output low level, observation circuit rollover states.
Claims (2)
1, a kind of desk lamp of may command illuminance, it is characterized in that, form by illuminance control assembly, operating circuit parts and power circuit parts, be electrically connected between each parts, the operating circuit parts are made up of fluorescent tube, resistance and relay and are electrically connected, and the power circuit parts are made up of bidirectional switch, transformer, electric capacity, electrical appliance module 7806 and diode and are electrically connected.
According to the desk lamp of claims 1 described a kind of may command illuminance, it is characterized in that 2, described illuminance control assembly is to adjust resistance by photo resistance, NE555 time base module, resistance, relay and illuminance scope, each element is carried out and is electrically connected.
