Description

Technical Field

[0001] This utility model relates to the field of LED lighting technology, and in particular to a lighting power supply. Background Technology

[0002] The power supply for the lamp provides power to the lamp, for example, by controlling the lamp's switch and its lighting effects. The lamp's controller typically consists of a housing and a circuit board mounted inside the housing. Appropriate electronic components are installed on the circuit board according to the usage requirements, and these components are connected to form the corresponding circuit.

[0003] In existing controllers, the circuit board is located inside the housing. To prevent liquid from entering the housing, the housing is usually sealed. Therefore, the circuit board is located in the enclosed space of the housing. The circuit board usually divides the space inside the housing into a first space and a second space. The first space is the space between the front of the circuit board and the housing, and the second space is the space between the back of the circuit board and the housing.

[0004] To facilitate the control of the switching on and off of lights and their lighting effects, a wireless signal receiver is often included in the circuit design. The operator controls the wireless signal transmitter to communicate with the wireless signal receiver and then selects the desired lighting effect.

[0005] However, because the circuit board is sealed inside the housing, the housing obstructs wireless signal communication. Therefore, the signal emitted by the wireless transmitter is weakened inside the housing. Furthermore, since the wireless receiver is mounted on the front of the circuit board, if the wireless signal enters the housing and first reaches the secondary space, the circuit board's obstruction further weakens the signal strength. Consequently, when the distance between the wireless transmitter and the lamp power supply is far, the operator will not respond after operating the wireless transmitter. Often, the wireless transmitter needs to be brought closer to the lamp power supply before the signal can be received by the wireless receiver. In such cases, the purpose of controlling the lamp's lighting effect via wireless signal is lost. Utility Model Content

[0006] This invention provides a lamp power supply that enables a wireless signal receiver to successfully receive wireless signals.

[0007] The technical solutions to the above technical problems are as follows:

[0008] A power supply for a lamp includes a housing, a circuit board, and a wireless signal receiver. The circuit board is installed inside the housing and has a first circuit. The wireless signal receiver is installed on the circuit board and electrically connected to the first circuit. The circuit board has through holes or notches for the wireless signal to pass through. Alternatively, at least a portion of the housing is a light-transmitting part.

[0009] In this invention, when the signal emitted by the wireless transmitter enters the housing, it is received by the wireless signal receiver after passing through the through hole or notch provided in the invention. The presence of the through hole or notch, or the presence of the light-transmitting part, can improve the efficiency of the wireless signal receiver in receiving the wireless signal.

Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of this application are still within the scope of this application.

[0024] like Figures 1 to 6As shown, the power supply for the lamp of this utility model includes a housing 1, a circuit board, and a wireless signal receiver 3. Each part and the relationship between them are described in detail below.

[0025] The housing 1 includes a main housing 1a, an end cap 1b, and conductive pins 1c. The main housing 1a is injection molded. The main housing 1a or the end cap 1b is preferably made of a light-transmitting material, meaning that light (e.g., infrared light) can pass through the entire main housing 1a or end cap 1b, which facilitates the passage of wireless signals through the main housing 1a or end cap 1b into the interior of the housing 1. The end cap 1b is injection molded, and the main housing 1a is fixed to the end cap 1b. After the main housing 1a and end cap 1b are combined, they are preferably fixed by ultrasonic welding. The main housing 1a is fixed to the conductive pins 1c, which are integrally fixed with the main housing 1a during injection molding. The end cap 1b has mounting holes 1d. The end cap 1b also has an output socket 1g, on which a connector for insertion into a circuit board is fixed. The output socket 1g is used to connect a lamp A, which can be an LED string.

[0026] The circuit board includes a first circuit board 2, which is installed inside the housing 1. A slot 1h is provided inside the main housing 1a. The first circuit board 2 moves along the slot 1h into the main housing 1a, thereby dividing the internal space of the main housing 1a into a first space and a second space. The first space is the space between the front of the first circuit board 2 and the main housing 1a, and the second space is the space between the back of the first circuit board 2 and the main housing 1a.

[0027] The first circuit board 2 is equipped with a first circuit, which includes a rectifier unit, an EMC protection unit, a clamping unit, a main control unit for controlling the on / off state of the clamping unit through overcurrent and overvoltage detection, a transformer, and an energy storage and filtering unit for converting AC power to DC power and performing energy storage and filtering. The structure of these units is conventional and will not be described in detail here.

[0028] In this embodiment, the wireless signal receiver 3 is mounted on the first circuit board 2 and electrically connected to the first circuit. The first circuit board 2 has a through hole 2a or a notch 2b for the wireless signal to pass through, and the wireless signal receiver 3 mates with the through hole 2a or the notch 2b. At least a portion of the housing 1 is a light-transmitting portion, which corresponds to the through hole 2a or the notch 2b.

[0029] When the signal emitted by the wireless transmitter enters the housing, it is received by the wireless signal receiver 3 after passing through the through hole 2a or the notch 2b provided in this invention. The presence of the through hole 2a or the notch 2b prevents the first circuit board 2 from blocking the wireless signal, thus enabling the wireless signal receiver 3 to receive the wireless signal smoothly.

[0030] In this embodiment, the wireless signal receiver 3 is arranged parallel to the first circuit board 2. The wireless signal receiver 3 has conductive pins 3a, which are soldered to the first circuit board 2. The conductive pins 3a are bent. This allows the receiver head on the wireless signal receiver 3 to enter the through hole 2a or the notch 2b, which is more conducive to the wireless signal receiver 3 receiving wireless signals. When the wireless signal receiver 3 preferably uses an infrared receiver head, the light-transmitting part can directly correspond to the infrared receiver head.

[0031] When the circuit structure is complex, and the space inside the housing 1 for mounting the first circuit board 2 is limited, a second circuit board 4 is added to accommodate the complex circuit arrangement without changing the length and width of the housing 1. The second circuit board 4 has a second circuit on it, which is electrically connected to the first circuit. After the second circuit board 4 is fixed to the first circuit board 2, the angle formed between the second circuit board 4 and the first circuit board 2 is greater than 0° and less than 180°. This structure divides the complex circuit into two parts: a first circuit and a second circuit. The first circuit is arranged on the first circuit board 2, and the second circuit is arranged on the second circuit board 4. The second circuit board 4 is preferably arranged perpendicular to the first circuit board 2. This not only utilizes the remaining space inside the housing 1 but also avoids increasing the product volume.

[0032] The first circuit board 2 has a socket 2c. The second circuit board 4 is soldered to the first circuit board 2 after it is connected to the socket 2c. Alternatively, the first circuit board 2 has a socket soldered to it, and the second circuit board 4 is plugged into and unplugged from the socket (similar to the connection between a discrete graphics card and a graphics card slot on the motherboard in a computer).

[0033] The second circuit board 4 has a clearance opening 4a, which cooperates with the wireless signal receiver 3. By using the clearance opening 4a to avoid interference with the wireless signal receiver 3 after the second circuit board 4 is installed, these components can be installed in a limited space.

[0034] This utility model also includes a button 5 and a cap 6 for changing the light-emitting effect. The button 5 is soldered to the first circuit board 2 and is also electrically connected to the first circuit. The cap 6 is engaged with the button 5 after being connected to the mounting hole 1d. The cap 6 is made of silicone. Applying pressure to the cap 6 transmits the pressure to the button 5, which then provides a corresponding pulse signal to the first circuit, thereby changing the light-emitting mode and thus enabling the product to have diversified control methods.

[0035] This invention also includes an LED indicator 7 for indicating the power operation mode of the indicator light. For example, the first circuit has a timing function (the timing function is prior art), and the status of the timing indicator 7 is reflected by the indication of the timing indicator 7. In this invention, the leads of the purchased LED indicator 7 are straight. Since the first circuit board 2 is perpendicular to the end cap 1b, and the arrangement direction of the first circuit board 2 is parallel to the axis of the cap 6, if the purchased LED indicator 7 is directly installed on the first circuit board 2 without modification, the LED indicator 7 will be far away from the cap 6, making it difficult for the user to observe the working status of the LED indicator 7. Therefore, in this invention, the leads of the LED indicator 7 are bent to fit with the cap 6. The leads of the LED indicator 7 are soldered to the first circuit board 2 and electrically connected to the first circuit. This gap fit between the LED indicator 7 and the cap 6 makes it easy for the user to observe the working status of the LED indicator 7. The cap 6 is made of a light-transmitting material (silicone), and the light emitted by the LED indicator 7 can pass through the cap 6 so that the user can observe the working status of the LED indicator 7 from the outside, thereby knowing the working mode of the controller. Of course, if necessary, the LED indicator 7 can be soldered to the first circuit board 2 without bending the pins of the LED indicator 7.

[0036] This utility model also includes a microphone 8, which is electrically connected to the first circuit after being soldered to the circuit board 2. Specifically, the microphone 8 and the first circuit board 2 are soldered together and then electrically connected to the first circuit. Preferably, this utility model also includes a plug 9 and a socket 10. The housing 1 has a receiving portion 1e and a through hole 1f that mates with the receiving portion 1e. The microphone 8 mates with the receiving portion 1e, allowing the microphone 8 to pick up the user's voice and thus control the lighting effect of the lamp A. This control method is conventional technology. After adding the plug 9 and socket 10, the microphone 8 is connected to the plug 9 via a wire. The plug 9 is inserted into the socket 10, and the socket 10 is soldered to the first circuit board 2 and then electrically connected to the first circuit. When assembling the end cap 1b with the main housing 1a, first plug 9 into the socket 10, and then combine the end cap 1b with the main housing 1a. This makes it easy to form an electrical connection between the microphone 8 and the first circuit board 2, reduces the assembly difficulty, and ensures the reliability of the electrical connection between the microphone 8 and the first circuit board 2.

[0037] This utility model is not limited to the above-described embodiments, for example:

[0038] like Figure 7The second circuit includes a chip 11, which can house a wireless signal receiver 3. The wireless signal receiver can be a 2.4G receiver, a WIFI module, or a Bluetooth module. It can communicate with the WIFI module and / or Bluetooth module through smart devices such as smartphones to control the light emission mode, thus giving the product a variety of control methods.

[0039] Alternatively, the wireless signal receiver 3 can be directly installed on the second circuit board 4. In this case, the wireless signal receiver 3 can be a 2.4G receiver, a WIFI module, a Bluetooth module, or an RF signal receiver, etc.
