Description

Technical Field

[0001] This utility model belongs to the field of light-controlled switch technology, and in particular relates to a high anti-interference LED power switch light control device. Background Technology

[0002] LED power switch light controls typically refer to power switches or dimming modules used to control LED lighting equipment. Neon lights, electronic displays, and LED light strips are becoming increasingly common in daily life. The most effective way to control these devices to automatically turn on or off is to install LED power switch light controls on the LED power supply that powers these devices. However, existing LED power switch light controls are easily affected by external environmental factors such as neon lights, electronic displays, and LED light strips. Since LED power switch light controls rely on photosensitive elements to receive light, lit neon lights, electronic displays, and LED light strips can interfere with the photosensitive element's accuracy in receiving light, thus reducing the control precision of the LED power switch light control.

[0011] As an optional solution of this utility model, the top of the light-transmitting light control head is provided with a light-transmitting six-sided mounting head, which facilitates the installation of the LED power switch light control.

[0012] As an optional solution of this utility model, the high anti-interference LED power switch light control device further includes a light-shielding cap, which is disposed above the light-transmitting light control head; the light-shielding cap includes a first limiting mechanism and a second limiting mechanism; the inner side of the first limiting mechanism is connected to the outer side of the light-transmitting light control head, and is used to limit the light-transmitting light control head; the inner side of the second limiting mechanism is connected to the outer side of the light-transmitting hexagonal mounting head, and is used to limit the light-transmitting hexagonal mounting head.

[0016] This application provides a highly anti-interference LED power switch optical control. By setting a male and female connector at one end of the power cord, the LED power switch optical control can be widely applied. A light-transmitting light control head allows selection of the light source direction from which the power can be turned on.

Ultimately, this improves the anti-interference capability of the LED power switch optical control. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0030] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0031] In specific embodiments of this utility model, such as Figure 1 As shown, a high anti-interference LED power switch light control device is provided, including a light shield 1, a light-transmitting light control head 2, a power cord 3, a light shield cap 7, and a male and female connector 8, wherein:

[0032] The male and female connector 8 is connected to the power cord 3; the power cord 3 is connected to the light shield 1; the light-transmitting light control head 2 is located on the upper part of the light shield 1; the light shield 7 is located above the light-transmitting light control head 2.

[0033] Reference Figure 2 and Figure 6 The light-shielding component 1 includes a light-shielding sleeve 4, a photosensitive element 5, and a light control circuit board 6. The power cord 3 passes through the bottom of the light-shielding sleeve 4. The photosensitive element 5 and the light control circuit board 6 are disposed inside the light-shielding sleeve 4.

[0034] In this specific embodiment of the present invention, the photosensitive element 5 is preferably a photodiode. The photodiode 5 is connected to the light control circuit board 6. The photodiode 5 receives the light emitted by the light source and converts it into a current signal, which is then transmitted to the light control circuit board 6. The light control circuit board 6 receives the current signal and compares it with a preset threshold to generate a power control signal. The power interface of the light control circuit board 6 is connected to one end of the power cord 3. The other end of the power cord 3 is connected to the male end of the male-female connector 8. The female end of the male-female connector 8 is connected to the LED power supply. The power control signal is transmitted to the LED power supply through the power cord 3 and the male-female connector 8 to realize the switching control of the LED power supply. At the same time, the LED power supply also provides voltage for the operation of the photosensitive element 5 and the light control circuit board 6.

[0035] In a specific embodiment of the present invention, the male and female connector 8 adopts a PH2.0-2PIN male and female connector, which can be used for most LED power supplies on the market.

[0036] Reference Figure 3 The light-shielding sleeve 4 is provided with an opaque light-shielding outer wall 401. A photosensitive port 402 is provided on the upper part of the light-shielding outer wall 401. The light-shielding outer wall 401 surrounds a light-shielding space 403. The photosensitive port 402 is located at the top of the light-shielding space 403. The photosensitive element 5 and the light control circuit board 6 are located in the light-shielding space 403. The light-shielding space 403 can block light entering from the direction of the photosensitive port 402. That is, the light around the photosensitive element 5 is blocked by the light-shielding outer wall. The photosensitive element 5 can only sense the light above the photosensitive port 402, thereby eliminating most of the light interference entering from the surroundings.

[0037] Preferably, the photosensitive element 5 is positioned within the light-shielding space 403 near the photosensitive port 402, and can be set to be at the same height as the photosensitive port. If the height of the photosensitive element 5 is too low, it will affect the reception of light source from the top of the photosensitive port 402; if the height of the photosensitive element 5 is too high, it will reduce the light-shielding effect.

[0038] Preferably, the lower part of the light-shielding sleeve 4 is provided with a power cord protective sleeve 404 for the power cord 3 to pass through. The length of the power cord protective sleeve 404 is only 1-3 cm, which can reduce the friction between the power cord 3 and the light-shielding sleeve 4. In a specific embodiment of the present invention, the light-shielding outer wall 401 is set to black, which has a better light-shielding effect than other colors.

[0039] Reference Figure 4 The light-transmitting light control head 2 is located on the upper part of the light-shielding sleeve 4. The light-transmitting light control head 2 is made of a light-transmitting material. A light-transmitting connector 201 is provided at the lower end of the light-transmitting light control head 2 for connection to the photosensitive port 402. A raised ring 405 is provided on the side of the light-shielding sleeve 4 to abut and seal against the bottom end of the light-transmitting connector 201, achieving better protection. A light-transmitting threaded connector 202 is provided around the light-transmitting connector 201. Specifically, the outer surface of the light-transmitting threaded connector 202 has several turns of thread, which are standard 1 / 2 thread and widely applicable. A light-transmitting soft silicone waterproof ring 203 is provided at the uppermost thread of the light-transmitting threaded connector 202. The light-transmitting soft silicone waterproof ring 203 is filled by the stress of the thread installation, enhancing the waterproofness of the light-shielding sleeve 4, preventing the photosensitive element 5 from getting damp and affecting its operation, and improving the stability and durability of this invention for outdoor use. The top side of the light-transmitting light control head 2 is provided with a circular brim, which contacts the light-transmitting soft silicone waterproof ring 203 to prevent the light-transmitting soft silicone waterproof ring 203 from sliding due to stress. A light-transmitting hexagonal mounting head 204 is provided at the center of the top of the light-transmitting light control head 2, facilitating the installation of the LED power switch light control. By using a wrench to align with the light-transmitting hexagonal mounting head 204 and rotating it, the threads of the light-transmitting threaded connector 202 are screwed into the threaded hole at the mounting location, completing the installation of the LED power switch light control.

[0040] Reference Figure 5 The light-shielding cap 7 is made of opaque material and can be detachably installed on top of the light-transmitting light control head 2. When the light-shielding cap 7 is installed on top of the light-transmitting light control head 2, it blocks light from entering the photosensitive port 402, thus keeping the photosensitive element 5 in a continuously dark state and losing its light-sensing control function. The LED light can be controlled to remain on or off according to actual needs. At the same time, the light-shielding cap 7 also protects the LED power switch light control, preventing operators from continuing to twist the light-transmitting hexagonal mounting head 204, which could cause the light-transmitting light control head 2 to break.

[0041] Specifically, the sunshade 7 includes a first limiting mechanism 701 and a second limiting mechanism 702. The first limiting mechanism 701 is located at the brim of the sunshade 7, and its inner side is connected to the outer side of the circular brim of the light-transmitting head 2, for limiting the light-transmitting head 2. The second limiting mechanism 702 is located below the top of the sunshade 7, and its inner side is connected to the outer side of the light-transmitting hexagonal mounting head 204, for limiting the light-transmitting hexagonal mounting head 204.

[0042] Preferably, the first limiting mechanism 701 includes a circular limiting groove, the depth of which is the same as the thickness of the brim of the light-transmitting head 2; the second limiting mechanism 702 includes a hexagonal limiting groove, the depth of which is the same as the height of the light-transmitting hexagonal mounting head 204.

[0043] Reference Figure 7 A circular protrusion 703 is provided at the center of the top of the sunshade 7, which makes it easy to remove the sunshade 7.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
