Compared with traditional high pressure sodium lamp, what’s the advantages of LED street lamp ?
As a semiconductor element, the effective life of LED street light can theoretically reach 50,000 hours, which is far higher than the 15,000 hours of high-pressure sodium lamps. Compared with high pressure sodium lamp, LED street light can reach more than 80 color rendering index, very close to natural light, in this light, the eye of recognition can be effectively, thus ensuring road safety.
In the street lamp open, high pressure sodium lamp needs a preheating process, the light from dark to bright need a certain amount of time, not only caused the waste of electricity, and affect the effective development of intelligent control. By contrast, LED street light can achieve optimal illumination at the moment of opening, there is no so-called startup time, so it can achieve good intelligent energy saving control.
From the light-emitting mechanism, the high pressure sodium lamp adopts mercury vapour luminescence, which, if not treated effectively, will inevitably result in the corresponding environmental pollution. LED is used in solid state lighting, and there are no harmful substances to the human body. It is a green light source.
The analysis from the aspects of the optical system, high pressure sodium lamp belongs to the omni-directional lighting, more than 50% of the light after reflector reflects is needed to illuminate to the ground, in the process of reflection, is bound to be part of the light loss, affect its utilization.
LED street light are unidirectional lighting, and light can be directed directly, so utilization is relatively high.
The light distribution curves of high pressure sodium lamps,need to be determined by the reflector, so there are a lot of limitations.
LED street light is using a distributed source, through the effective design of the electric light source, can make the light source of lamps and lanterns presents the ideal state, realize the reasonable light distribution curve adjustment, control the distribution of light, in the available irradiation range of lamps and lanterns, intensity of illumination is relatively uniform.
In summary, using LED street lighting is more energy saving and environmental protection compared with using high pressure sodium for lighting road lighting. There is no doubt that with the progress of science and technology, energy-efficient light source will be constantly emerging, as a professional manufacturer of LED street lights and lanterns, TEK innovation design, grasps the lighting the use of new technology and new equipment, always put the energy conservation and environmental protection work as the first place, TEK is a good choice for you.
