Halogen lamps are a light source that is actively used for outdoor and indoor lighting. Unlike standard incandescent lamps, the bulb of halogen models is filled with vapors of iodine, bromine, fluorine. Electric current, acting on the incandescent body, releases tungsten atoms, which react with halogens. The reaction is reversible, which allows you to extend the life of the halogen up to 12,000 hours. Plus: the chemical reaction is reflected in the stable intensity of the light flux.
Before buy halogen lamps, experts recommend understanding the scope. The increased light output allows the use of halogens for street projectors, cinema projection equipment, in the automotive and radio engineering industries.
Characteristics of halogen lamps
Among the indicative working qualities are:
- power (you can choose models from 1 to 20 kW);
- light output (the indicator starts at 15 Lm);
- wide operating temperature range (halogen lamp works stably at
- temperatures from -60 to + 100 ° C);
- even luminous flux without pulsation;
- high efficiency (the minimum indicator is 50%).
The wide range of halogen devices on the market allows you to choose the optimal solution for your application.
Halogen lamps: advantages and disadvantages
Subject to the rules of operation (switching on through a special transformer), halogens demonstrate economical energy consumption. Plus: the service life while maintaining the nominal performance exceeds the standard incandescent lamps by 2-3 times.
The increased luminous efficiency guarantees a stable luminous flux. Depending on the version, you can choose models with a warm or cold shade. Plus: even distribution of light eliminates eye strain, which affects the comfort of the microclimate.
Given the design features, halogen light sources tolerate temperature changes well, which allows them to be used for organizing outdoor lighting. The tightness of the lighting fixture will extend the life of the fixture.
Features of production exclude the use of harmful substances, so halogen lamps do not require special disposal.
The main disadvantage of the halogen is the strong heating (up to 500 ° C) of the flask. Given this feature, their use in chandeliers or other lighting fixtures made of low-melting material is prohibited. Mounting is only permitted when wearing gloves.
