Description

Technical Field

[0001] This utility model relates to energy-saving luminous remote control buttons and media. Background Technology

[0002] Currently, many home appliances can be controlled using remote controls, such as air conditioners, televisions, fans, etc. The buttons on the remote control are an indispensable part of the remote control.

[0003] Many electronic products now use remote controls, but remote controls are not easy to operate in the dark, and it is easy to press the wrong button, causing unnecessary trouble.

[0004] Current solutions: 1. Some remote controls place an LED under each button. When a button is pressed, all LEDs are lit, or the LEDs remain lit continuously, resulting in significant power consumption and frequent battery replacements. 2. Some remote controls embed light pillars into the buttons. These pillars absorb light to emit a glow at night. However, remote controls are generally placed in dimly lit areas, so the light absorption is insufficient, resulting in a poor nighttime glow that is short-lived and gradually becomes blurry, failing to achieve the desired effect. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an energy-saving luminous remote control button and medium.

[0006] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0007] An energy-saving luminescent remote control button, the button includes an MCU, the MCU being electrically connected to a silicone keypad containing luminescent powder, a photosensitive sensor, and a keypad backlight panel;

[0008] Silicone keypad has a backlight panel B;

[0009] Backlighting components and key holes are provided on the key backlight panel;

[0010] The photosensor corresponds to the phosphorescent powder;

[0011] The MCU receives the light signal from the photosensitive sensor button.

[0012] The keypad backlight panel has a backlight;

[0013] Backlight, used to illuminate the phosphorescent powder.

[0014] As a further improvement to the above technical solution:

[0015] The MCU is also electrically connected to the LCD screen.

[0016] The keypad backlight panel contains two purple LEDs.

[0017] The photosensitive sensor is located below the silicone keypad.

[0018] The MCU is electrically connected to the key scanning circuit; the key scanning circuit has a key S; key S is electrically connected to the MCU through the SWL channel.

[0019] The keypad backlight panel includes the base of transistor Q1, which is electrically connected to the MCU;

[0020] The collector of transistor Q1 is connected to the power supply VBAT through LED D1, and the emitter is grounded.

[0021] The circuit of the photosensitive sensor includes a comparator U3;

[0022] In comparator U3,

[0023] The output terminal is connected to VCC through resistor R13, and the PHOTO output terminal is connected to the MCU.

[0024] At the input terminal, the positive terminal is divided into three paths: one path is connected to VCC through resistor R11, the second path is grounded through photoresistor R12, and the third path is grounded through capacitor C10.

[0025] The negative terminal is divided into two paths: one path is connected to VCC through a variable resistor R9, and the other path is grounded through a resistor R10.

[0026] A medium includes a remote control, on which the aforementioned remote control buttons are provided.

[0027] This invention features buttons made of silicone with added luminescent powder for more uniform illumination. During the day, it absorbs light to replenish energy, thus saving energy through automatic supplemental lighting.

[0028] Make a backlight panel under the silicone button, and embed two purple LEDs in the backlight panel. The luminous powder has the best absorption effect on purple light. When the MCU detects the silicone button through the photosensitive sensor and the light dims, turn on the purple LEDs to provide supplementary lighting for 10 minutes, which can solve the problem of the silicone button gradually becoming blurry.

[0029] A photosensitive sensor is used to detect the brightness of the buttons. The silicone buttons, which contain luminescent powder, store energy to emit light, saving energy. The backlight panel can provide supplementary lighting when the button light is weak, solving the shortcomings of current button backlights. The production process is simple, uses less material, has low cost, is suitable for various environments, and is easy to mass-produce.

[0030] This utility model is reasonably designed, low in cost, sturdy and durable, safe and reliable, simple to operate, time-saving and labor-saving, cost-saving, compact in structure and easy to use. Attached Figure Description

[0040] like Figure 1-8 An energy-saving luminescent remote control button and medium, comprising an MCU, wherein the MCU is electrically connected to a silicone keypad containing luminescent powder, a photosensitive sensor, and a keypad backlight panel;

[0041] The MCU is also electrically connected to the LCD screen;

[0042] The keypad backlight panel contains two purple LEDs;

[0043] Silicone buttons containing luminescent powder can automatically absorb some energy when exposed to light during the day. The stronger the light intensity, the more energy is absorbed and the longer the light-emitting time, thus achieving energy saving.

[0044] A photosensitive sensor is used to detect the brightness value of the luminescent silicone powder.

[0045] In actual use, the remote control is usually placed in the living room or bedroom, where the indoor lighting is not strong enough and the light storage energy is not sufficient. The brightness and effect of the light at night do not meet the requirements. Therefore, the light sensor detects the brightness of the buttons. If the light of the buttons is too weak, the MCU will activate the supplementary light function. The MCU turns on the blue backlight to supplement the light. The silicone buttons have luminous powder. After 10 minutes of supplementary light, the buttons can be lit for more than 8 hours. This achieves the desired effect while saving the remote control battery power.

[0046] The LCD display circuit mainly serves as a human-machine interface. The MCU controls the LCD screen to display different information and transmits the information variables that the remote control needs to control.

[0047] The MCU main control circuit is the core component of the remote control. It acquires input signals and controls output signals, serving as the information control center.

[0048] The key scanning circuit in the MCU scans and analyzes a key and executes the corresponding key function.

[0049] The photoresistor circuit is installed under the silicone button to detect the button brightness. The MCU continuously detects the brightness through analog and digital channels. When it finds that the brightness of the silicone button is lower than the set value, it turns on the silicone button backlight to provide supplemental light to the silicone button.

[0050] The backlight is mainly used to illuminate the silicone buttons. The MCU detects the brightness of the silicone buttons and controls the backlight to turn on or off.

[0051] Work process:

[0052] The characteristic of a photoresistor is that its resistance gradually decreases as the light intensity gradually increases and gradually increases as the light intensity gradually decreases. This change in resistance generates different voltage division values.

[0053] In one scenario, the light intensity is directly collected by the MCU ADC and calculated.

[0054] In the other two scenarios, a reference voltage is set. When the light intensity decreases, the resistance of the photoresistor increases, and the voltage divider increases. When the voltage divider is greater than the reference voltage, the comparator outputs a high level to the MCUIO for data acquisition.

[0055] When the MCU detects that the brightness of the silicone button is lower than the set value, the comparator output goes high, and the MCU starts to provide supplemental lighting to the silicone button. The supplemental lighting intensity is adjusted based on the current brightness of the silicone button, and the PWM control of the backlight circuit can be adjusted from 10% to 100% to activate the supplemental lighting.

[0056] When there is light during the day, the silicone buttons can also absorb light themselves to replenish energy and save energy.

[0057] The silicone keypad on the remote control can emit light at night, making it easy for users to see the corresponding functions on the buttons and operate them to achieve the desired results. For example, information such as air conditioning mode, temperature, and fan speed can be displayed on the LCD screen via the MCU, making it convenient for users to operate.

[0058] This utility model is described in detail for the purpose of making the disclosure clearer, and the prior art will not be listed one by one.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
