Problems solved by technology

These instant-on, instant-on, instant-off lights in the living room have the following outstanding disadvantages: 1. Every time the lamp is turned on, there will be repeated strong current impact on the lamp, which will reduce the service life of the lamp and reduce its safety
2. Although low-brightness lamps such as soft lights can reduce the stimulation of light on glasses, their brightness is not high and damage human vision; ordinary fluorescent lamps are full of brightness, but they are very dazzling when they are turned on, which is not good for human eye health.
3. Immediate extinguishment of lamps will make it difficult for human eyes to adapt to the sudden dark environment, and even cause dizziness

Embodiment Construction

[0010] A fading light such as figure 1 As shown, it includes an illuminating lamp EL and a switch S. The illuminating lamp EL and the switch S are connected in series to the 220V mains, and it is characterized in that it also includes a fade-in and fade-out circuit. Thyristor VT1, thyristor VT2, Zener diode VS, diodes VD1, VD2, resistors R1-R3, capacitor C and switch S, the connection relationship of each component is, the anode of the bidirectional thyristor VT1, the anode of the diode VD2, The negative poles of the Zener diode VS are all connected to the negative pole of the mains, the gate of the bidirectional thyristor VT1 is connected to the positive pole of the Zener diode VS, and the negative pole of the bidirectional thyristor VT1 is also connected to the Zener diode after being connected in series with the resistor R1 The positive pole of VS is connected, the negative pole of the bidirectional thyristor VT1 is also connected with the positive pole of the diode VD1 and...

Abstract

The invention discloses an illuminating lamp turning bright and dark gradually, which comprises an illuminating lamp EL and a switch S, wherein the illuminating lamp EL and the switch S are connected in series to 220V commercial power. The illuminating lamp turning bright and dark gradually is characterized by further comprising a circuit turning bright and dark gradually, wherein the circuit turning bright and dark gradually comprises a bidirectional thyristor VT1, a thyristor VT2, a voltage regulator diode VS, a diode VD1, a diode VD2, resistors R1-R2, a capacitor C and a switch S. The illuminating lamp has the effect of turning bright and dark gradually, so that damage to human eyes caused by turn-on brightness and turn-off darkness is avoided, and the lamp is more user-friendly; and meanwhile, the lamp turning bright and dark gradually can be used for preventing strong current caused by repeated turn-on and turn-off from damaging the lamp impact, and has the advantages of longer service life and higher safety in comparison to an ordinary lamp.

Description

technical field [0001] The invention relates to an illuminating device, in particular to a gradually brightening and fading illuminating lamp with fading effect when turned on and off. Background technique [0002] Today, bedroom lamps are emerging in an endless stream. In order to enable users to obtain more comfortable and soft lighting, businesses have launched "soft lights" and "comfortable lights". Regardless of whether the soft light or the ordinary fluorescent lamp or incandescent lamp reaches the maximum brightness when the switch is pressed, it goes out instantly when the switch is turned off. These instant-on and off-off lamps in the living room have the following outstanding disadvantages: 1. Every time the lamp is turned on, a strong current repeatedly impacts the lamp, reducing the service life of the lamp and reducing its safety. 2. Although low-brightness lamps such as soft lights can reduce the stimulation of light to glasses, their brightness is not high an...
