Description

Adaptive multifunctional LED key case

technical field

The invention relates to a key case with lighting function, in particular to an self-adaptive multifunctional LED key case which can automatically adjust the lighting of lamps and lanterns according to the intensity of ambient light.

Background technique

The current key bags are generally ordinary bags with key chains, which do not have lighting functions. When people need to use keys in a dark environment, it is very inconvenient, and it is easy to take the wrong key. A lot of inconvenience. In the prior art, although some key cases with lighting functions are designed, the lighting system of such key cases cannot change with the light of the environment, which is easy to cause waste.

Contents of the invention

The purpose of the present invention is to provide a key case that can automatically adjust the lighting according to the brightness of the environment when people use the key, so that people can take out the correct key and use it smoothly under various ambient light conditions.

In order to achieve the above object, the present invention provides an adaptive multifunctional LED key case, the key case is in the shape of a foldable wallet, has two folding lines, and two stickers are arranged at the two folding lines, and the stickers are The contact switch device that controls the on-off of the circuit by distance, when the key case is folded, the patch is separated, so that the circuit is in a disconnected state, when the key case is opened, the patch is in contact, and the circuit is in a conducting state, which ensures When the key case is opened, the LED light in the key case will not light up even in low light conditions.

The two folding lines divide the key case into three parts: left, middle and right; the middle part is provided with a row of colored LED lights, and each light is equipped with a key ring for placing keys, and a useful key ring is provided in the interlayer. In the bag for money; the right part is provided with a white LED light; the left part is provided with a photodiode, and the photodiode is arranged at a place where the thumb is easy to touch when holding the key bag, so as to prevent the photosensitive LED from being turned on when the LED is on. The diode is disconnected to ensure that when the key case is opened, the thumb presses it so that it cannot receive light and is always in a conducting state.

The advantage of the present invention is that LED is used as the light source, the appearance design can be folded like a wallet, and it is also designed with a pocket for money, so that it integrates the functions of a wallet and a key case, and simultaneously adopts a touch switch and The combination of photosensitive switches makes the key case more practical and convenient. The design of the contact switch prevents the key case from turning on the LED light when it is not in use; the photosensitive switch enables the key case to automatically adjust the LED light on and off according to the intensity of the ambient light during use, which can effectively avoid the waste of electric energy , and at the same time realize the adaptive control of the key bag. In addition, because the LED itself has the advantages of small size, low power consumption, long service life, high brightness and low heat, the invention has low cost and low power consumption, which is beneficial to energy saving.

Detailed ways

As shown in Figure 1, the self-adaptive multifunctional LED key case of the present invention is designed as a wallet shape with two folding lines 1, so that the key case is in a folded state when placed in a pocket of clothing, and the two folding lines 1 Divide the key case into three parts, the interlayer of the middle part is provided with a pocket for money, and the inner layer of the middle part uses a colored LED light as a light source, the purpose of which is to facilitate the user to distinguish the key by color 4 . The colored LED lamps 3 adopted in the present invention are neatly arranged on one side of the middle part of the key case in a horizontal direction, and each LED lamp has a key ring for placing the key 4 under each LED lamp, so that the key 4 can be placed along the folding line 1 of the key case , wherein the number of colored LED lamps 3 is 3 to 6, and it is more appropriate to use 3 LED lamps in the preferred mode.

As shown in Figure 1, a row of 3 to 6 white LED lamps 5 for illuminating the keyhole is arranged on one side of the inner layer of the right part of the key case, preferably 3. The white light LED lamp 5 can make things convenient for people to see the position and direction of the keyhole clearly, and it is convenient to open the door at night.

The inner layer of the left part of the key case is designed with a photosensitive diode 2, which is used to sense the light intensity in the environment and control the on and off of the LED light.

In addition, as shown in FIG. 2 , the self-adaptive multifunctional LED key case of the present invention is provided with a control circuit combining a contact switch and a photosensitive switch. Among them, the contact switch is to place the patch on the fold of the key case, and control the on-off of the circuit through the distance between the two patches. When the key case is opened, the patch is in contact, so that the circuit is connected. After folding the key case, the patch breaks off. This is to ensure that when the key case is not opened, the LED will not light up even in weak light conditions. After the contact switch is turned on, the photodiode 2 turns on the circuit when the light is weak, so that the LED can emit light, which can provide us with light, and the brightness of the light can be controlled according to the resistance and power supply in the circuit. When there is light in the daytime, the photodiode 2 makes the circuit in a disconnected state due to the light, so that the LED is not bright. In addition, in order to prevent the photodiode 2 from being disconnected when the LED is on, we placed the photodiode 2 in a place where the thumb can easily touch it when holding the key bag, and let the thumb press it so that it cannot receive light, so that it is always on. connected state. Such a control circuit combining the contact switch and the photosensitive switch enables the key case to realize self-adaptive control.

The self-adaptive multifunctional LED key case of the present invention can meet the various needs of people for storing keys and money, and can also facilitate nighttime travel by means of the light on the key case, and at the same time can realize self-adaptive control of lighting, and save electric energy. At the same time, it brings great convenience to people's life.

The above is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Anyone familiar with the technical field within the technical scope disclosed in the present invention, according to the technical solution of the present invention Any equivalent replacement or change of the inventive concepts thereof shall fall within the protection scope of the present invention.
