Today, Yuepu Optoelectronics shares how to choose adjustable LED bulbs

When choosing LED dimmable bulbs, multiple factors such as light parameters, dimming performance, quality and safety need to be considered. The following are the specific key points for selection:

Optical parameters

Luminous flux: Luminous flux is an indicator for measuring the brightness of a light bulb, with the unit being lumens (lm). Generally speaking, the higher the luminous flux, the brighter the bulb. The demand for luminous flux varies in different usage scenarios. For instance, a living room might require 800 to 1200lm, while a bedroom would suffice with 300 to 500lm.

Color temperature: Color temperature determines the color of light, and its unit is Kelvin (K). Low color temperature (2700K-3000K) lighting presents a warm yellow color, creating a cozy and comfortable atmosphere, and is suitable for bedrooms and dining rooms. High color temperature (5000K-6500K) lighting is white in color, bright and clear, and is suitable for places such as kitchens and studies that require high brightness and high clarity.

Color rendering index The Color rendering Index (CRI) reflects the ability of light to reproduce the color of an object. The higher the value, the better the color rendering. Generally, LED dimmable bulbs with a CRI of over 80 are chosen, which can better display the true color of the object. For places with high color requirements, such as art galleries and clothing stores, bulbs with a CRI of over 90 should be selected.

Dimming performance

Dimming range: High-quality LED dimmable bulbs usually have a wide dimming range, smoothly dimming from 1% to 100% to meet the brightness requirements in different scenarios. For example, when watching movies, the brightness can be adjusted to below 10%, while for daily lighting, it can be adjusted to 100%.

Dimming methods: Common dimming methods include knob dimming, remote control dimming, mobile phone APP dimming and intelligent voice dimming, etc. The knob dimming operation is simple and suitable for local and small-scale dimming. Remote dimming makes it convenient to control the lights within a certain distance. The dimming function of the mobile phone APP can achieve remote control and scene setting. Intelligent voice dimming is even more convenient and can control the lights through voice commands.

Dimming smoothness: A good LED dimmable bulb will not experience flickering or jumping during the dimming process. The light brightness changes evenly and smoothly, providing a comfortable visual experience.

Quality and Safety

Brand and Certification: Choose LED dimmable bulbs from well-known brands, as their product quality and after-sales service are more guaranteed. At the same time, it is necessary to ensure that the light bulbs have passed relevant certifications, such as 3C certification, CE certification, etc. These certifications indicate that the products meet safety, environmental protection and other standards.

Service life: The service life of LED bulbs is usually measured in hours. Generally, the service life of high-quality products is over 25,000 hours. Calculated based on 8 hours of use per day, they can be used for more than 8 years.

Heat dissipation performance: Good heat dissipation is the key to ensuring the lifespan and performance of LED bulbs. Poor heat dissipation can lead to increased light attenuation and reduced brightness of the bulbs. Choose bulbs with high-quality heat dissipation materials, such as aluminum heat dissipation shells, for better heat dissipation effect.

Adaptability

Lamp head types: Common lamp head types include E27, E14, B22, etc. Before purchasing, it is necessary to confirm the lamp head type of the lamp and choose a matching LED dimmable bulb.

Power matching: Check whether the working voltage and frequency of the bulb match the household power supply system. Generally, household electricity is 220V, 50Hz. Ensure that the bulb can work normally.

Intelligent system compatibility: If your home already has an intelligent lighting system, such as Mi Home or Huawei Smart Life, you should choose LED dimmable bulbs that are compatible with it to achieve intelligent linkage and control.
