DALI Dimming Is Becoming the Industry Standard
Professionals in the lighting industry know that traditional 0-10V and TRIAC dimming systems often reveal issues over time-such as complex wiring, inconsistent dimming performance, poor compatibility between brands, and high long-term maintenance costs. The DALI protocol addresses these pain points at the source.
DALI (Digital Addressable Lighting Interface) is a globally recognized standard for lighting control. The latest DALI-2 standard (IEC 62386-207) enables seamless interoperability between devices from different manufacturers-a crucial advantage for contractors. In a single project, power supplies, sensors, and control panels might come from various brands; DALI-2 certification ensures they communicate effectively without compatibility conflicts.
Commercial projects across Europe, the Middle East, and Southeast Asia now routinely specify DALI systems, and office buildings, hotels, and hospitals in China are rapidly following suit. Smart lighting is no longer just a trend; it has become a standard requirement. Selecting a stable, reliable DALI power supply is a decisive factor in the quality of the final project delivery.
Key Design Advantages of the EUCHIPS DALI Driver
The first thing you notice about this EUCHIPS power supply is its slender profile: 280mm long, just 30mm wide, and 21mm thick. This elongated design isn’t merely for aesthetics; it allows the unit to fit into the narrow spaces found in linear lights and tri-proof fixtures.Professionals working on linear lighting projects know that standard box-shaped power supplies simply won’t fit. You are often forced to choose between a bulky fixture that compromises aesthetics or an external power supply that drives up installation costs. The dimensions of the EUCHIPS DALI Driver allow it to fit perfectly inside most linear light profiles, resulting in a sleek, minimalist fixture. Feedback from our projects indicates that installation efficiency improves by at least 30%.The non-isolated architecture is another key design feature of this EUCHIPS DALI Driver. While the term “non-isolated” might raise safety concerns for some, such worries are unfounded. Non-isolated solutions are highly mature in the LED lighting sector and are particularly well-suited for applications like linear lighting. The high-voltage, low-current output characteristics perfectly match the circuitry of linear light boards, minimizing line losses.
The efficiency is a genuine 93%–94%. This figure isn’t just an ideal value from a lab test; it reflects data from actual project operations. For an office building project with 1,000 lights operating 10 hours a day, the difference in electricity costs over a year between using a 94%-efficient power supply and an 88%-efficient one can amount to tens of thousands of yuan. This is a key factor for clients when calculating costs.
The selectable current design is highly practical. It offers eight current settings that can be configured directly via DIP switches-no computers or programming required. Given the often-limited conditions at installation sites, electricians can simply make the adjustment with a small screwdriver. Since the same power supply model can accommodate various light board specifications, inventory management is greatly simplified; stocking just a few models allows us to meet the needs of the vast majority of projects.
Active PFC circuitry comes standard. It delivers a power factor exceeding 0.95 and very low THD. Large commercial buildings have strict requirements for power grid quality, and power supplies lacking PFC often fail to pass inspection. EUCHIPS DALI drivers excel here, featuring active PFC across the entire series without requiring customers to pay extra for the option.
The power supply is the heart of an LED fixture; if it fails, the entire light stops working. EUCHIPS DALI drivers feature comprehensive protection circuitry, including overload, short-circuit, and over-voltage protection.
Short circuits are the most common issue in real-world use, often caused by wiring errors during installation or damaged light boards. A high-quality power supply will automatically cut off the output when a short circuit occurs and resume operation once the fault is cleared, preventing burnout.
A design lifespan of 50,000 hours supports a 5-year warranty. This commitment isn’t made lightly; it relies on excellence in every aspect-from component selection and thermal design to the manufacturing process.
Many clients ask if heat dissipation becomes an issue when the power supply is housed inside the light fixture. The elongated casing acts as a heat sink, and the non-isolated design generates minimal heat; under normal operating conditions, the casing temperature is only about 15°C higher than the ambient temperature, keeping it well within safe limits.

Application Scenarios
Modern office buildings predominantly use linear lighting fixtures. The EUCHIPS DALI driver integrates seamlessly into the fixture housing, while DALI dimming enables features such as occupancy sensing, constant illuminance control, and scene switching. Modes like “Work,” “Meeting,” and “Lunch Break” can be toggled with a single click.Underground parking lots are humid environments that demand high power supply reliability. Space within tri-proof fixtures is limited, making the slim, linear form factor of this power supply an ideal fit. DALI control enables lights to brighten when vehicles arrive and dim when they leave, resulting in significant energy savings. Space within recessed panel lights is also limited, yet this power supply fits easily inside. Hospitals demand exceptional lighting stability; flickering is unacceptable, and dimming must be smooth. DALI digital dimming excels in this regard, offering deep dimming down to 0.1% with absolutely no flicker, thereby protecting the eyesight of medical staff and students.Space for shelf and under-shelf lighting in supermarkets is extremely limited. Slim power supplies can be concealed directly within the fixture housing, eliminating the need for visible external drivers. DALI systems allow for time-based dimming-full brightness during peak hours and dimmed levels during off-hours-which saves energy and extends the lifespan of the lighting fixtures.
Procurement and Usage Recommendations
When selecting a DALI power supply, prioritize certification. DALI-2 certification is a crucial benchmark; without it, compatibility cannot be guaranteed. Some low-cost power supplies on the market claim to support DALI but lack official certification, leading to various issues when interfacing with gateways or sensors from other brands and resulting in high rework costs.
Allow for a power margin. For instance, if an LED board requires 36W, choose a 38W power supply rather than running it at full capacity. Maintaining a margin of approximately 10% helps extend the unit’s lifespan.
Match the current setting to the LED board. Always verify the LED board’s rated current before adjusting the DIP switches. Setting the current too high accelerates lumen depreciation, while setting it too low results in insufficient brightness. It is recommended to test the current and brightness with a single unit before proceeding with mass installation.
Ensure proper wiring. Use shielded twisted-pair cable for the DALI bus and route it away from high-voltage power lines to prevent interference. Adhere to DALI standard limits: the bus length should not exceed 300 meters, and the system should support no more than 64 devices.As an authorized EUCHIPS distributor, Gainer LED maintains a comprehensive stock and provides readily available technical support.
