Understanding the Power Consumption of Exterior Linear Light Fixture

Exterior linear light fixture is becoming increasingly popular due to their cost-effectiveness and versatility in industrial, commercial, and other outdoor applications. With remarkable lumen output and high luminous efficiency, these fixtures cater to diverse lighting needs. Win-E Illumination takes pride in offering excellent quality exterior linear light fixtures that are not only easy to install and maintain but also save labor and packaging costs while minimizing waste. Our intelligent systems support dimming, emergency power supply, sensors, and track spotlights, ensuring a seamless lighting experience. In this blog, we will delve into the power consumption aspects of exterior linear light fixtures, shedding light on the importance of optimizing switching losses and effective maintenance techniques.

Understanding Power Consumption in Exterior Linear Light Fixtures:

The power consumption of exterior linear light fixtures can be divided into two primary parts: switching loss and conduction loss. It is crucial to note that in most scenarios, especially in LED utility drive applications, switching losses tend to be more significant than conduction losses. The magnitude of switching losses is influenced by factors such as power tube capacitances (cgd and cgs), chip driving ability, and operating frequency. To address power tube heat issues, the following strategies can be employed:

A. Selecting appropriate MOS power tubes:

It is essential to move beyond considering only the on-resistance when choosing power tubes since smaller internal resistances can lead to larger cgs and cgd capacitance. For instance, power tubes like 1N60, 2N60, and 5N60 exhibit significant differences in cgs values, ranging from 250pF to 1200pF. Hence, when selecting power tubes, it is crucial to strike a balance.

B. Frequency and chip driving ability:

Proper consideration should be given to the impact of frequency on power tube performance. Additionally, the driving ability of the chip plays a pivotal role in optimizing power tube operation.

Maintenance Tips for Exterior Linear Light Fixtures:

To ensure the longevity and performance of exterior linear light fixtures, proper maintenance is essential. Here are some key maintenance practices:

1. Disassembling and re-gluing:

In cases of improper handling or positional misalignment during glue adjustments, exterior linear light fixtures should be disassembled and re-glued. This ensures that the fixtures remain waterproof and retain their optimal functionality.

2. Component analysis during repairs:

When repairing exterior linear light fixtures, it is crucial to disassemble and analyze the light source components. This allows for effective diagnosis and recovery of valuable components from waterproof power supplies and light source modules. Defective light sources, such as COB and anti-lumen, may require the removal of original packaging materials for accurate analysis.

3. Identifying the root cause of failures:

In cases of faulty exterior linear light fixtures, it is essential to identify the actual cause before replacing them. Hastily replacing a defective fixture without identifying the underlying issue can lead to recurring short circuits and potential damage to the light source chips. Thorough investigation and diagnosis are vital before implementing the appropriate solution.
