detail about a number of shortcomings ↑

  1. The disadvantages of these devices include a high price.However, in spite of the notable initial investment, their use results in significant cost savings in the future.
  2. street lighting LED heat is subject to degradation.To such a lamp can work normally, it needs a high quality heat dissipation.This function is performed by the substrate on which LEDs are soldered.But if they are poorly soldered, it will lead to the formation of cavities disturbing heat removal and, as a consequence, - damage of a lamp.
  3. Also, these devices are very sensitive to voltage drops.If there is a power failure, the work lamp can be broken due to overheating of its body.If the body temperature and the temperature of the sealant will be equal, the device may malfunction.
  4. Street LED lamp can break due to dysfunction of electrodes that are indispensable in the construction of this device.The metal from which they are made, is subject to diffusion.If it happens, there is a great risk of getting metal particles to the action of the semiconductor.This can lead to device failure.

design and classification of devices ↑

device specifics ↑

Operation LED based on the principle of emission of light waves, which occurs as a result of an electrical pulse.

Street lamp with light - a kind of complex semiconductor devices, ie,LEDs are mounted in a lightweight and durable aluminum body covered with protective paint.

How are LED Street Lighting Fixtures

Street Lights structurally different from their counterparts for the premises.In accordance with the SAE (Rules ustr. Islands electrical) are mounted on supports from 4 to 11 m in height, so that the light beam was directed downward.Typically, the support 1 mounted on the lamp 2 by means of brackets of stainless steel.Apparatus suggest the possibility of adjusting the color characteristics of the radiation flux.

Types of LED lamps for street ↑

Street Lights LED may be in the form of spotlights, lights, and be represented by a decorative street lighting devices (dyurafleks, Rope, rulers and grids).

1. Spotlights.Industrial - set mainly on large objects.With their help illuminate the streets near the sports complex, illuminate the facades of buildings, open spaces, parking lots and other outdoor facilities with a large territory.Small floodlights installed in backyards.They may also have a white and colored light at various angles of radiation.

Rope is used primarily to create contours in the landscape design
  • Fixing - operate in a constant glow.
  • Cheyzing - with their help made the dynamic street lighting.
  • Multicheyzing - dynamic LED lighting-class "luxury".
  • Chameleon - street lighting controller.

4. Dyurafleks different from other similar devices waterproof, ease and flexibility that simplifies operation and installation of the luminaire.It may be fixed to any surface and in any environment.It is often used as decorative landscape lighting.
