Desk lamp function classification
The publisher：Time：2015-01-22 10:04:17View：
1, [lamp]: can be placed on the flat bench with a lighting, multi band lamp shade.
2, []: reading light for reading and design or the use of light.
The lamp is a kind of people living in the household appliances for lighting. It is generally divided into two kinds, one kind is a column type, one kind is clamped type. Its function is to light concentrated in a small area, easy to work and study. The general desk lamp bulb is eye protection desk lamp incandescent lamp, energy saving lamp, popular on the market, part of lamp and "emergency function" that comes with power, for blackout emergency lighting.
Function introduction
Desk lamp, according to the use of functional classification: reading lamp, decorative lamp, portable lamp.
Reading lamp, the lamp body shape is simple and light, refers to the lamp is used exclusively to read a book and writing, this table can be generally direction and brightness of light adjustment height of poles, lighting, mainly is the reading function.
Decorative lamp luxurious appearance, materials and styles, the lamp body structure is complex, used for decorative effect of space, the decorative function and lighting function are equally important.
Bedroom lamp has far surpassed the lamp itself value, the lamp has become a rare works of art, the decorative light decoration ideas, lamp decoration function is more obvious.
In addition to reading, the decorative lamp. The latest technology is like a robot, movement, dance, auto dimming, play music, clock, video,
Touch and other functions, in particular the lamp ceramic technology also has the collection value.
Lighting plays a role in what the Home Furnishing life? In the night, lighting is a wizard, is to create a warm atmosphere of the expert. Through the lighting levels, make the space is full of vitality; during the day, the lamps and lanterns of decorative art room, furniture, cloth art, it and decor. Dotted with the beauty of life, light plays a role play a decisive role in the living space. ]
The 1 touch control type
LED lamp
The principle of touch type desk lamp is installed inside the electronic touch type IC lamp of the electrode sheet and touch form a control loop. When the human body touches the induction electrode sheet, a touch signal by pulsating direct current to generate a pulse signal is transmitted to the touch induction end, then touch sensing terminal sends a trigger pulse signal, you can control the lights; such as touch again once, a touch signal will be followed by the pulsating direct current to generate a pulse signal is transmitted to the touch induction end at this time, touch sensing end will stop making the trigger pulse signal, when the alternating current zero, the lamp extinguished naturally. But sometimes after power failure or voltage instability will also have their own light, if you touch the received signal sensitive paper or cloth can be controlled.
2 adjustable brightness
Principle of adjustable desk lamp is composed of a resistor R2, resistance, capacitance potentiometer RP1 C capacitance phase shifting
Circuit, adjusting the RP1, you can change the V of the bidirectional thyristor conduction angle, so as to change the light bulb brightness EL. Resistance R1 current limiting resistor. The charging speed of C is related with the parallel loop. In R1, the RP2 is fixed, the Ooko Yukomin resistance RL shunt resistance to decide. When the grid voltage rises, the brightness of the light increases, the RL resistance becomes smaller, the shunt increases, rising voltage across the capacitor C slow V, thyristor conduction angle decreases, the output voltage is decreased, the brightness of the light down; otherwise, when the grid voltage drop, RL increased resistance, shunt decreases, the conduction angle of the thyristor increasing the brightness of the light, the output voltage is increased, the increase of. As a result, the brightness of the light is automatically stabilized in the setting value.
