How to distinguish the quality of led induction light?
Driven by smart home and energy-saving lighting, led induction light is widely used in homes, offices, shopping malls, parking lots and other places due to its advantages of high efficiency and energy saving, intelligent sensing and convenient operation. However, there are many brands of led human body induction light on the market, and the quality varies. Many consumers often find it difficult to judge the quality when purchasing.
So, how to distinguish the quality of led induction light? This article will conduct a detailed analysis from multiple professional perspectives to help consumers make a wise choice.
What is led induction light?
led induction light is a lighting device that uses LED (light-emitting diode) as a light source and integrates intelligent sensing technology. Its main feature is that it can automatically turn on or off the light according to environmental changes or human activities. Common sensing methods of led human body induction light include:
● Infrared sensing (PIR sensing): Control the light switch by detecting changes in infrared emitted by the human body.
● Microwave sensing: Use microwave radar to detect the movement of objects, and can sense the target even if it penetrates obstacles.
● Light sensing control: Automatically adjust the light brightness or switch status according to the intensity of ambient light.
● A high-quality led induction light should have: stable sensing function, high-quality LED light source, reliable power drive, good heat dissipation design and durable shell material. Next, we will analyze in detail how to identify the quality of led induction light from multiple key aspects.
What are the core indicators for identifying the quality of led induction light?
1. LED light source quality
One of the core components of led human body induction light is the LED light source, and its quality directly affects the brightness, life and energy efficiency of the lamp. The quality of LED light source can be judged from the following aspects:
● Brightness (lumen value): high-quality led human body induction light has a higher luminous flux (unit: lumen lm) and can provide sufficient brightness, while low-quality led human body induction light may have serious light decay problems.
● Light decay: high-quality LED light sources have less light decay and can maintain stable brightness after long-term use, while inferior LEDs will become significantly dimmer after a period of use.
● Color rendering index (CRI): The color rendering index (Ra value) reflects the color reproduction ability of the light source. The color rendering index of a high-quality LED induction light should be greater than 80, which can truly reproduce the color of the object.
● Color temperature stability: Different LED induction lights have different color temperature ranges (generally 2700K-6500K). Good quality LEDs have stable color temperatures and will not have color cast or flicker.
● Identification method: Check the product's technical parameter table, give priority to well-known brand LED chips (such as CREE, Osram, Lumileds, Samsung, etc.), and observe whether the light is uniform and has no obvious light spots or color casts.
2. Sensor performance
The sensor is one of the key components of the LED induction light, which determines the intelligent response capability of the lamp. If the sensor performance is poor, it may cause the LED human body induction light to fail to sense correctly or be frequently triggered by mistake.
Methods to judge the quality of sensors:
● Sensing range: High-quality LED induction lights have reasonable sensing distance (generally 3-8 meters) and sensing angle (120°-180°), and can accurately detect targets.
● Reaction speed: Good sensor lights light up quickly, usually within 0.5 seconds to complete sensing and light up.
● Anti-interference ability: Low-quality sensors are easily affected by external interference (such as temperature changes, metal reflections, etc.), resulting in false triggering or missed sensing, while high-quality sensors can effectively filter interference.
● Adjustment function: Some high-end LED induction lights support sensing sensitivity adjustment and delayed shutdown time adjustment, which users can flexibly set according to their needs.
● Identification method: Test the sensing sensitivity in different environments (such as daytime and nighttime), and observe whether the sensor light is falsely triggered or cannot be lit.
3. Power drive quality
The power drive module of the LED induction light is responsible for providing stable current and voltage, which affects the service life and safety of the LED human body induction light.
Methods to judge the quality of power driver:
● Voltage stability: A high-quality LED power driver can provide a stable DC voltage to prevent LED flickering or overheating.
● Power factor (PF): The power factor of a high-quality power driver should be ≥0.9 to improve energy utilization and avoid wasting electricity.
● Overcurrent and overvoltage protection: A good LED driver has an overload protection function to prevent current fluctuations from damaging the LED chip.
● Whether to use an isolated power supply: High-end LED induction light uses an isolated driver power supply, which is safer and more reliable, while low-end products may use a non-isolated power supply, which poses a risk of electric shock.
● Identification method: Use a multimeter to test whether the output voltage is stable, and check the power factor parameter in the LED human body induction light product specification.
4. Heat dissipation performance
Good heat dissipation design can effectively extend the service life of the LED induction light and prevent LED overheating from causing light decay or damage.
Methods for judging the heat dissipation structure:
● Heat dissipation material: high-quality LED induction light uses aluminum alloy heat sink with good thermal conductivity, while inferior products may use ordinary plastic shell with poor heat dissipation effect.
● Heat dissipation area: The larger the surface area of the heat sink, the better the heat dissipation effect. Some high-end LED induction lights use fin-type design to improve heat dissipation efficiency.
● Temperature rise test: After lighting the LED induction light for a long time, touch the surface of the lamp body. If the temperature is too high, the heat dissipation may be poor.
● Identification method: Choose an LED induction light with heat dissipation fins or aluminum alloy, and observe the temperature changes during use.
5. Shell material and protection level
The shell of the LED induction light not only affects the durability of the product, but also determines its dustproof and waterproof capabilities.
How to identify the quality of the shell?
● Material: High-quality LED induction light usually uses aluminum alloy + PC material, which is durable and impact-resistant, while inferior products may use inferior plastic and are easy to damage.
● Waterproof grade (IP grade): For LED induction lights used outdoors or in humid environments, IP65 and above are better, while IP44 and above for indoor lamps can meet daily needs.
● Process details: Observe whether the joints, buttons and other positions of the LED human body induction light are tight and seamless to prevent dust or moisture from entering.
● Identification method: Check whether the surface workmanship of the LED human body induction light is fine, and check the protection grade parameters of the product.
How to quickly identify the quality of the LED induction light?
✅ LED light source quality: high brightness, color rendering index Ra>80, no flicker, low light decay
✅ Sensor performance: high sensitivity, fast response, strong anti-interference ability
✅ Power drive: stable voltage, high power factor, over-current and over-voltage protection
