ETB1-EW87/BLA/39-31-7A Application Field and Working Principle

Lamps - Incandescents, Neons

The ETB1-EW87/BLA/39-31-7A is an incandescent lamp with a special anodized alumina/antimony trioxide coating. It uses halogen gas to extend its life and provide self-rectification for good white illumination. The anodized alumina/antimony trioxide coating increases the intensity and uniformity of the lighting output and improves the color characteristics. In addition, the symmetrical electric field in the lamp is beneficial for the operation and stability.

The ETB1-EW87/BLA/39-31-7A is intended primarily for general illumination applications in ambient lighting installations, such as corridor, aisles and accent lighting. The 6k-23k color temperature range allows it to fit well in any environment, including both indoor and outdoor lighting. Due to its outstanding characteristics, the ETB1-EW87/BLA/39-31-7A is ideal for creating high visibility and atmosphere.

The ETB1-EW87/BLA/39-31-7A mainly consists of three parts: an anodized alumina/antimony trioxide coated bulb, an outer sealed envelope and a high temperature protective thimble. The anodized alumina/antimony trioxide coated bulb has been optimized to give an improved white lighting output with superior color consistency. The outer sealed envelope encases a mixture of halogen gas and a large amount of tungsten vapor, which is responsible for the increased luminous efficacy. The protective thimble also helps to retain the heat within the lamp, enabling a long operating life.

In operation, the ETB1-EW87/BLA/39-31-7A is powered by an AC voltage source, typically between 110 to 240V. The electric current flows through a resistance filament, which heats up and creates an electrical arc in the bulb. This arc ionizes the gas in the bulb, creating a plasma, which is highly visible and supplies the light. In addition, the electric current also releases electrons, which collide with the anodized alumina/antimony trioxide coating on the surface of the bulb, creating an excited state that produces ultraviolet radiation, which is then converted to visible white light.

The ETB1-EW87/BLA/39-31-7A is an ideal choice for general illumination applications, offering excellent performance and long operation life. The anodized alumina/antimony trioxide coating on the bulb helps to improve the color characteristics of the light, while the mixture of halogen gas and tungsten vapor ensures a good luminous efficacy. With its symmetrical electric field, it provides stable operations and has a long life expectancy.
