Description

Technical Field

[0001] The present invention belongs to the technical field of dimming, and in particular relates to a lamp that realizes dimming function by pressing a mask and a method for realizing the same. Background Art

[0002] With the development of technology, more and more lighting fields choose to use LED products, especially high-power LED products. Due to the advantages of high light efficiency, long life, green environmental protection, intelligent control, etc., LED has become a new generation of lighting source.

[0003] With the popularity of LED lights, people have higher and higher requirements for the lighting status of LED lights. Currently, the main way to adjust the lighting status on the market is to use a dial switch or an infrared remote control to adjust the status. However, the infrared remote control is easily lost during use.

[0004] Chinese patent application number 202010579612.6 discloses an infrared integrated circuit for adjusting the light state. The infrared signal is reflected by the human body to the infrared integrated receiving tube IR1, and a carrier signal is added to the transmission to increase the anti-interference ability. The controller U2 identifies the user's intention by performing timing judgment on the output signal of the infrared integrated receiving tube IR1, thereby achieving the user's purpose of adjusting the light state.

[0005] Although the above-mentioned public patent integrates the remote control directly into the lamp to prevent the remote control from being lost, the above-mentioned public patent identifies the user's dimming intention through the reflection of infrared signals by the human body. In order to avoid false triggering, the dimming control can only be achieved by covering the top of the sleeve with the palm of the hand multiple times in a certain pattern during dimming, which is inconvenient to operate. Summary of the invention

[0006] The purpose of the present invention is to provide a lamp that realizes dimming function by pressing a mask, so as to solve the problems raised in the above background technology. The lamp that realizes dimming function by pressing a mask provided by the present invention has the characteristics of avoiding the loss of the remote control and facilitating rapid dimming.

[0007] Another object of the present invention is to provide a method for realizing a lamp with a dimming function by pressing a mask.

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a lamp that realizes dimming function by pressing a mask, comprising an LED driver, an LED light source, a dimming controller U1, an infrared receiving tube IR1 and an infrared transmitting tube IR2, wherein the positive electrode of the LED light source is connected to the LED+ end of the LED driver, the negative electrode of the LED light source is connected to the LED- end of the LED driver, the PWM end of the LED driver is connected to the 14th pin of the dimming controller U1, the 1st pin of the dimming controller U1 is connected to the positive end of the infrared transmitting tube IR2, the negative end of the infrared transmitting tube IR2 is connected to the GND end, the 2nd pin of the dimming controller U1 is connected to the positive end of the infrared receiving tube IR1, the negative end of the infrared receiving tube IR1 is connected to the GND end, the infrared receiving tube IR1 and the infrared transmitting tube IR2 are symmetrically installed at both ends of a long strip PCB board, and the long strip PCB board is installed on the mask of the lamp body.

[0009] In order to power the infrared receiving tube IR1 and the dimming controller U1, a linear regulator U2 is further included, wherein pin 2 of the linear regulator U2 is connected to the V+ terminal of the LED driver, pin 1 of the linear regulator U2 is the GND terminal, and pin 3 of the linear regulator U2 is respectively connected to the positive terminal of the infrared receiving tube IR1 and pin 9 of the dimming controller U1.

[0010] Furthermore, a resistor R2 is connected between the 3rd pin of the linear regulator U2 and the positive terminal of the infrared receiving tube IR1.

[0011] Furthermore, a resistor R1 is connected between the pin 1 of the dimming controller U1 and the positive terminal of the infrared emitting tube IR2.

[0012] Furthermore, the LED light source includes a plurality of LED lamp beads connected in series.

[0013] In order to store the current PWM output signal so as to maintain the current state output when powered on next time, further, the chip of the dimming controller U1 is a N76E003 type with a storage unit.

[0014] In the present invention, the method for realizing a lamp that realizes a dimming function by pressing a mask further comprises the following steps:

[0015] (i) After the lamp is powered on, the dimming controller U1 reads the PWM output signal stored in the storage unit, and then lights up the LED light source through PWM output;

[0016] (2) The infrared receiving tube IR1 continuously receives the infrared signal continuously emitted by the infrared emitting tube IR2;

[0017] (3) When the user presses the mask, the mask deforms, causing the long strip PCB to deform, the relative angle between the infrared transmitting tube IR2 and the infrared receiving tube IR1 changes, and the intensity of the infrared signal received by the infrared receiving tube IR1 changes;

[0018] (iv) When the dimming controller U1 recognizes that the intensity of the infrared signal received by the infrared receiving tube IR1 changes, it adjusts the PWM output signal to change the lighting effect of the LED light source.

[0019] In the present invention, further, in the method for realizing a lamp that realizes a dimming function by pressing a mask, in step (iv), after the dimming controller U1 completes a PWM output signal adjustment, the current PWM output signal is stored in the storage unit.

[0020] Furthermore, in the present invention, in the method for realizing a lamp that realizes a dimming function by pressing a mask, the PWM output signal stored in the dimming controller U1 overwrites the previous PWM output signal.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The present invention causes the long strip PCB board to deform by pressing the mask, so that the relative angle between the infrared transmitting tube IR2 and the infrared receiving tube IR1 changes, thereby changing the intensity of the infrared signal received by the infrared receiving tube IR1. The dimming controller U1 identifies whether the intensity of the infrared signal received by the infrared receiving tube IR1 changes to determine the dimming operation, thereby adjusting the PWM output signal and changing the lighting effect of the LED light source;

[0023] 2. The present invention performs dimming by pressing the mask, and the possibility of false triggering is low. Therefore, a dimming action can be achieved by pressing the mask only once, thereby facilitating rapid dimming operation;

[0024] 3. The lamp of the present invention does not need to open a hole to place a dial switch, which is beneficial to the waterproofing of the lamp.
