Problems solved by technology

However, the facts have proved that the final application range of these inventions is very small, and it is difficult to promote them on a large scale. The reason is that people are not used to and inconvenient to stay in an environment that is suddenly fully bright and suddenly completely dark in daily life. , and whenever the lights need to be turned off, it seems that there is no need to rely on the "automatic switch"
In short, as daily life facilities, these "automatic switches" are not practical and humanized enough to arouse people's desire to use them.
In addition, an important reason why these "automatic switches" can only work between the two states of "on" and "off" is that so far almost all electric lights are directly lit by the mains, and the mains Cannot simply be used directly to randomly change the brightness of lights
[0003] At present, in order to achieve the purpose of randomly changing the brightness of lights, the only thing that can be relied on is the switching power supply technology. Volts are randomly adjustable, with an output power of tens of watts to more than kilowatts, and a dimmable power supply with the characteristics of high efficiency, small size, and low cost is not easy.

Embodiment 1

[0042] See (1) in Figure 2. As shown in the figure is a schematic diagram of an AC-AC dimming power supply with a bidirectional thyristor (SCR1) as a switching element and two dimming potentiometers (RW1) and (RW2).

[0043]In the figure, the power consumption of the lamp head (DT-1) is taken from the mains (AC) through the triac (SCR1), so the current flowing through the lamp head is also AC; the trigger resistor (R2) and the delay capacitor (C3) and The stepped Zener diode (W1) forms a delay trigger, which provides an initial trigger time for the thyristor (SCR1) and determines the maximum brightness of the lamp head (DT-1); The detected signal is filtered by the capacitor (C4) and the resistor (R8), and then input to the dual voltage comparator (IC1-LM393), and then the seventh pin and the second pin of the dual voltage comparator (IC1-LM393) Output two levels of high and low changes, and absorb the current of the trigger resistor (R2) through the dimming potentiometer (RW...

Embodiment 2

[0046] See (2) in Figure 2. As shown in the figure is a schematic diagram of an AC-AC dimming power supply with a bidirectional thyristor (SCR1) as a switching element and only one segmental dimming switch (K2).

[0047] This embodiment cancels the dimming potentiometer (RW1) that can adjust the brightness of the lamp head when there are people in the previous figure, and replaces the dimming potentiometer that can adjust the darkness of the lamp head when there is no one with a segmental dimming switch (K2) (RW2), in addition to the original resistor (R4), two series resistors (R4+1) and (R4+2) are added; the segmental dimming switch (K2) is a three-state switch, which is compatible with the above three With only the combination of resistors, three different grades of darkness of the lamp head when no one is present can be obtained.

[0048] Compared with the previous figure, this embodiment has two differences. One: After canceling the dimming potentiometer (RW1), it is imp...

Embodiment 3

[0052] See (1) in Figure 3. As shown in the figure, it is a schematic diagram of an AC-AC dimming power supply with a bidirectional thyristor (SCR1) as the switching element, only one segmental dimming switch (K2), and a photosensitive probe (MV1).

[0053] In this embodiment, a photosensitive probe consisting of a photosensitive triode (MV1), a flow expansion triode (V1), and resistors (R9) and (R10) is installed on the basis of the previous figure; during the day, the photosensitive triode (MV1) is excited, and the current expansion transistor (V1) is turned on, so that the trigger voltage cannot be established on the delay capacitor (C3), and the bidirectional thyristor (SCR1) does not work; at night, the photosensitive transistor (MV1) As of now, the automatic dimming energy-saving lamps work normally.

[0054] After the photosensitive probe is added, it is not always necessary to turn on and off the dimming power supply through the power switch, and even cancel the power...

Description

technical field [0001] The invention relates to a lamp, in particular to a lamp capable of automatic dimming, and belongs to the technical fields of lighting and power electronics. Background technique [0002] As we all know, "turning off the lights" when there is no one is the easiest way to save power. In order to simulate "turning off the lights", there have been many "automatic switches", the most representative of which is the "pyroelectric switch". Infrared sensor automatic switch". However, the facts have proved that the final application range of these inventions is very small, and it is difficult to promote them on a large scale. The reason is that people are not used to and inconvenient to stay in an environment that is suddenly fully bright and suddenly completely dark in daily life. , and whenever the lights need to be turned off, it seems that there is no need to rely on the "automatic switch". In short, as daily life facilities, these "automatic switches" ar...
