Bộ điều khiển đèn bet88 com là một mạch điều khiển cấp nguồn cho điốt phát sáng (đèn bet88 com). Để chiếu sáng đèn bet88 com, phải đặt một điện áp xác định trong khi cung cấp dòng điện. Nếu dòng điện được cung cấp không đổi thì độ sáng (độ chói) của đèn bet88 com. luôn ổn định mà không có bất kỳ biến động nào. Do đó, vai trò của bộ điều khiển đèn bet88 com là cung cấp điện áp/dòng điện ổn định cho đèn bet88 com.
Today, bet88 com drivers are being manufactured by numerous semiconductor companies, resulting in a vast array of products. However, when classified by application, they fall into two main categories: for "lighting" and for "decoration."
Our company (THine Electronics) is one of the semiconductor manufacturers producing bet88 com drivers. The distinguishing feature of our products is that they are all designed for decorative lighting applications (Fig. 1). Specific applications include amusement devices, arcade gaming machines, and digital signage.

Yêu cầu về nguồn điện cho ứng dụng chiếu sáng
Vậy, hiệu suất và chức năng cần có đối với bộ điều khiển đèn bet88 com dùng trong các ứng dụng chiếu sáng và trang trí là gì? Chúng ta hãy xem xét kỹ hơn.
As the name suggests, bet88 com drivers for lighting are designed for lighting fixtures and equipment, primarily intended to drive white LEDs. Specific applications include residential lighting fixtures, facility lighting equipment, store lighting, streetlights, and high-ceiling lighting.
One of the key requirements for bet88 com drivers used in lighting applications is power. To achieve bright (high-luminance) lighting fixtures, a larger current must be supplied to the LEDs. For this reason, products capable of supplying drive currents as high as several amperes have been introduced into the market for bet88 com drivers for lighting applications.
In addition, dimming functionality is essential. Dimming refers to the ability to adjust the brightness of the LEDs. For instance, turning a knob installed on a wall or using a dedicated remote control allows users to adjust the brightness of the LEDs gradually. There are two main methods for achieving dimming. One is analog dimming, which adjusts the bet88 com brightness by changing the amount of current supplied to the bet88 com. The other is pulse width modulation (PWM) dimming, which controls the brightness by adjusting the bet88 com's on-time and off-time within a given period. Increasing the on-time brightness of the bet88 com while shortening it dims the bet88 com. The PWM signal determines the length of the on and off periods, and brightness is controlled by varying the duty cycle (the ratio of on-time to off-time) of the PWM signal.

Hiệu suất cao cho các ứng dụng chiếu sáng trang trí
Mặt khác, trình điều khiển bet88 com dành cho chiếu sáng trang trí được thiết kế để điều khiển đèn bet88 com RGB, chứa ba loại đèn bet88 com—đỏ (R), xanh lục (G) và xanh lam (B)—trong một gói duy nhất. kiểm soát độ sáng của từng đèn bet88 com RGB, có thể thể hiện nhiều màu sắc khác nhau. Khả năng này được sử dụng để hiển thị hình ảnh đủ màu sắc và tạo ra các hiệu ứng ánh sáng phức tạp. Các ứng dụng cụ thể bao gồm các thiết bị giải trí, máy chơi game arcade và bảng hiệu kỹ thuật số (Hình 2). 2).
A key feature required for bet88 com drivers used in decorative lighting is the ability to create diverse real-time effects via serial communication with addressing. To achieve the desired displays and colors, it is necessary to supply the appropriate current to each RGB bet88 com. PWM dimming functionality is used to adjust the current supplied to the LEDs. This PWM dimming function requires a wide dynamic range (the ratio of maximum to minimum supply current), fine resolution, and high precision in setting values.
For example, an 8-bit resolution, or 256 levels, is often required. If the brightness of each RGB bet88 com can be adjusted in 256 steps, a full-color display of 256 x 256 x 256 = approximately 16.77 million colors is possible (Fig. 3). Of course, depending on the application, lower resolution than 8-bit may also be sufficient.

Các sản phẩm hiện có (THL3512/THL3514) Sử dụng giao diện LVDS
Như đã đề cập trước đó, chúng tôi đã thương mại hóa trình điều khiển đèn bet88 com cho hệ thống chiếu sáng trang trí được thiết kế để điều khiển đèn bet88 com RGB.
These bet88 com drivers are used in combination with a CPU (Fig. 4). The CPU outputs data signals and clock signals that specify the color to be displayed to the bet88 com driver via an interface (e.g., a 3-wire serial interface). The bet88 com driver processes these signals internally and generates PWM signals that control the brightness of each RGB bet88 com. These PWM signals are supplied to the RGB LEDs via output channels, causing the LEDs to emit light and display the specified color.
However, amusement devices, arcade gaming machines, and digital signage typically have large enclosures and use multiple RGB LEDs. Even when multiple RGB LEDs are used, only one RGB bet88 com is directly connected to the CPU. The remaining RGB LEDs are connected in a cascade or multi-drop configuration (Fig. 5).

Mở rộng dòng sản phẩm (THL3526)
Tuy nhiên, giao diện LVDS cũng có nhược điểm do phương pháp truyền vi sai của nó, số lượng dây tăng lên so với truyền dẫn một đầu "Mặc dù khả năng chống nhiễu ở chế độ chung được hoan nghênh nhưng chúng tôi muốn tránh. tăng diện tích PCB do có thêm hệ thống dây điện." Vì những cân nhắc về thiết kế như vậy, một số nhà sản xuất thiết bị điện tử đã ngần ngại sử dụng máy sấy bet88 com có giao diện LVDS.

Hỗ trợ điện áp không đổi và điều khiển dòng điện không đổi
Ngoài ra, THL3526 còn có ba tính năng được thiết kế để cải thiện khả năng sử dụng của trình điều khiển bet88 com cho các nhà sản xuất thiết bị điện tử.
The first feature, continuing from our previous products, is the integration of a buffer circuit into the interface for connecting bet88 com drivers (Fig. 6). This buffer circuit functions as a repeater or re-driver. In other words, it receives the single-ended signal (TTL signal) flowing through the interface, reshapes the signal waveform, and retransmits it. As a result, the transmission distance of the interface can be extended. As mentioned earlier, amusement devices, arcade gaming machines, and digital signage often have large enclosures, which can result in longer distances between adjacent bet88 com drivers. The integration of the buffer circuit in this product addresses such cases, allowing for extended distances between drivers.
The second feature is the ability of a single bet88 com driver to support both constant current driving and constant voltage driving. By configuring the terminals, either constant current or constant voltage driving can be selected. The benefit of this feature is that it simplifies procurement and inventory management. There is no longer a need to procure two different types of drivers—one for constant current and one for constant voltage—allowing inventory management to be consolidated into one type.
The third feature is the enhanced electrostatic discharge (ESD) tolerance. This was achieved by optimizing the circuit design of the bet88 com driver. Our internal testing confirmed that the device withstands 8 kV of ESD in the human body model (HBM). This surpasses many competitors' products, which typically offer 2 kV.
The new product is packaged in a 48-terminal QFN with a mounting area of 7 mm x 7 mm. The maximum drive current is 40 mA in constant current mode and 80 mA in constant voltage mode. The brightness adjustment supports up to 256 levels, and the supply voltage range is 4.5 V to 5.5 V.
With the launch of this new product, our lineup of decorative bet88 com drivers has been expanded. This allows manufacturers to select the most suitable bet88 com driver according to the design philosophy of their amusement devices or arcade gaming machines.
