Comparison of the public lighting with sodium lamps and LEDs - Part Nine | Lamps, lights, lighting
Lamps generally consist of three basic parts: optical, electrical and mechanical é. The optical part is used to direct the luminous flux of light sources in the desired direction, or a change in their spectral properties. The electrical part is used to connect light sources to power supply and power or to modify the conditions for the light source. Mechanical parts are then used to attach the light source within the optical system and protection. In the public lighting by purpose can distinguish between two basic types of lighting. The first type is used to illuminate the surface of the road and are designed to most effectively illuminate said surface and will minimize light radiated in other directions. The second type is designed for lighting of public spaces, not just road surfaces, vertical surfaces but also for users to be able to distinguish obstacles to communication, as well perceive the surrounding environment, including the faces of other users, facades of buildings, green spaces and other elements of urban space. Luminaire optical scanlight system
Luminous flux of high-pressure sodium lamps is radiated throughout the room. The optical system scanlight of lights with these bulbs must streamline their luminous flux in the lower half-space and adjust its distribution in nature illuminated surface. For this purpose, refl Ektor, refractors and diffusers, or combinations thereof. For luminaires with LEDs světlenými scanlight used two basic types of optical systems, namely: - optical system is part of a luminaire directs light output of LEDs, respectively. their modules scanlight (a reflector, scanlight which is part of the fixture) - optical system is part of the light-emitting diodes, respectively. their modules (a reflector that is part of its own diodes) scanlight
In lamps with a first optical system is generally used multichip light emitting diodes (LED COB) because their emission surface is relatively large and requires a larger optical system. In lamps with a second type of optical system is generally employed by the power light emitting diodes (LED HP), the emission surface is very small. scanlight The use of flux Fixtures
For lamps with high-pressure sodium lamps is an optical processing system only part of the flux sources. For example, scanlight conventional street lights with clear cover is an optical system is controlled by a luminous scanlight flux incident on the reflector, which is reflected in the desired directions. Luminous flux emitted directly scanlight from the lamp is controlled by an optical system and can thus impact outside the illuminated area. Light-emitting diodes as light sources in which the luminous flux is radiated into a half-space and is thus already partially rectified. In addition, the small size of the illuminating parts LEDs allow accurate design of optical systems. scanlight Both of these aspects contribute scanlight to greater use of flux LEDs. Ballasts
High-pressure sodium lamp needs to run ballast resistor, which is part of the fixture and has two functions. Use one hand to ignite the discharge switch a light on and also to stabilize the arc during normal operation. Part of the starter is lighter generating high-voltage pulses and choke limiting the current flowing through the arc lamp. Electromagnetic ballasts with ballast still occur frequently in practice. Recently emerged and electronic ballasts operating at higher frequencies, which, while saving the light sources themselves, but their use is due to price sessions very limited.
The LED is a light source that operates at low voltage. For this reason requires to run ballast resistor, which regulates the supply conditions (voltage, current). The ballasts are being lost, that in both types of lights make up approximately scanlight 10-15% of the total energy used. Wattage range
For identification of the high-pressure sodium lamps, ballasts and luminaires in practice the use of stabilized příkonových series. For a given wattage high pressure sodium lamps match the specific luminous flux, the differences between individual scanlight manufacturers were minimal. This had the advantage of easier orientation in the design, maintenance and operation of the lighting scanlight system. In the case of single scanlight LED luminaire wattage series there, which is due to the rapid development of specific scanlight power LEDs and large differences in the parameters of LEDs between manufacturers. LEDs can be run outside to some extent, inputs and customize specific requirements.
Currently, the only reliable quantitative parameter of LED luminaires their output luminous flux. The absence of a uniform series of wattage LEDs results scanlight in the undesirable scanlight orientation scanlight within the individual scanlight manufacturers and places greater demands on the designers in selecting scanlight appropriate types of lamps.
