tunnel color temperature sensor

The tunnel color temperature sensor is an intelligent sensing device designed to measure the color temperature (in Kelvin) of light sources within tunnels. It is primarily used in tunnel lighting control systems to ensure visual comfort and safety at tunnel entrances, exits, and throughout the interior. Its features include high-precision measurement, fast response times, strong resistance to interference, adaptability to changes in both bright and dim lighting conditions, and support for long-term stable operation. It is widely used in highway tunnels, railway tunnels, urban underpasses, and intelligent traffic lighting systems to enable on-demand dimming, energy-saving control, and enhanced traffic safety.

Introduction

The tunnel color temperature sensor is a device specifically designed to measure the color temperature (expressed in kelvins, K) of tunnel lighting sources. It monitors changes in color temperature in real time at the tunnel entrance, in transition zones, and within the tunnel, and transmits this data to the lighting control system. This enables automatic lighting adjustment, ensuring drivers’ visual adaptation and driving safety while also addressing energy-saving and intelligent management requirements.

Structure color temperature sensor

  • Optical Filter: Separates incident light into specific wavelength bands (typically RGB or multi-channel filtering) to mimic the human eye’s response to different colors, thereby improving the accuracy and stability of color temperature calculations.
  • Photodiode / Sensor Element: The core light-sensitive component that converts received light signals into electrical signals.
  • Signal Conditioning Circuit: Amplifies, filters, and reduces noise in weak electrical signals.
  • A/D Converter (Analog-to-Digital Converter): Converts analog electrical signals into digital signals for subsequent processing and transmission.
  • Microcontroller Unit (MCU): Performs calculations on multi-channel data, converts it into color temperature values (CCT) using algorithms, and performs data calibration and compensation.
  • Temperature Compensation Module: Calculates the color temperature value and outputs the data.
  • Boîtier de protection : A waterproof and dustproof enclosure designed for outdoor or tunnel environments.
  • Interface de sortie : Such as RS485 or MODBUS, used for data transmission.

FAQ

À quoi sert un capteur de température de couleur ?

Un capteur de température de couleur est utilisé pour mesurer la température de couleur corrélée (CCT) des sources lumineuses en temps réel. Il est couramment utilisé dans les systèmes d'éclairage des tunnels, l'éclairage public intelligent et le contrôle de l'éclairage industriel pour garantir des conditions d'éclairage stables et confortables.

Comment fonctionne un capteur de température de couleur dans un tunnel ?

Un capteur de température de couleur pour tunnel détecte le spectre de la lumière ambiante et le convertit en données CCT (Kelvin). Les données sont envoyées à un système de contrôle de l'éclairage, qui règle automatiquement les lampes en fonction des besoins d'éclairage de l'entrée, de la transition ou de l'intérieur du tunnel.

Quelle est la plage de mesure d'un capteur de température de couleur ?

La plupart des capteurs industriels de température de couleur couvrent une large gamme allant de 1500K à 25000K, ce qui les rend adaptés aux environnements lumineux chauds et froids dans les applications intérieures et extérieures.

Un capteur de température de couleur peut-il fonctionner dans des environnements difficiles ?

Oui, les capteurs CCT de qualité industrielle sont conçus avec des indices de protection élevés (tels que IP65/IP66/IP67), ce qui permet un fonctionnement stable dans des conditions d'humidité élevée, de poussière, de pluie et de température extrême.

Pourquoi un capteur de température de couleur est-il important dans les systèmes d'éclairage de tunnels ?

Il permet d'ajuster la couleur et l'intensité de l'éclairage à l'entrée et à la sortie des tunnels, réduisant ainsi l'inconfort visuel des conducteurs et améliorant la sécurité de la conduite lors des changements soudains de luminosité.

Quelles sont les industries qui utilisent les capteurs de température de couleur ?

Ils sont largement utilisés dans l'ingénierie des tunnels, les villes intelligentes, les systèmes de transport routier, Les projets de contrôle de l'éclairage industriel, d'éclairage architectural et de surveillance de l'environnement.
