TEK lighting introduces you to LED street light distribution requirements

LED street light distribution could be projected onto various areas of the road as much as possible, be in different regions, according to the road to get to meet the requirements of road lighting. Light distribution of LED street lamp light distribution design is accurate in place is whether it can replace traditional street lamps one of the key factors.

The following is a description of LED street lighting distribution requirements by TEK lighting.
1,Characteristics of light distribution
In the road lighting, if the light source of LED street lamp is not distribution, the light on the road surface is a large circular spot, and Some light falls out of the road and is not used.

In order to meet on the brightness, illumination, evenness, and make the most of the light distribution on the road as far as possible to improve the utilization rate of light and reduce unnecessary waste, usually, LED street light needs to be distribution, and the light produced by the LED street lamp shines on the road, and the light pattern or spot formed  rectangle is better.

2,Standard lighting requirements for road lighting
According to the requirements of "urban road lighting design standards", road lighting road is divided into fast and main roads, sub-trunk roads and secondary roads, and LED road lighting and lighting requirements should meet the requirements.

3,Light distribution of LED street lamps
The spatial distribution of luminous intensity is often called the distribution curve.
At the bottom of the street lamp, the light intensity should be the minimum, and as the elevation Angle theta increases, the light intensity I increases.The function relation is: the expression of the matching optical curve.The ideal lighting curve of single luminaire for road lighting.

Because of the complexity of optical design, it is difficult to fully conform to the function relation with the optical design, so that the projection range of theta Angle can be reduced, and the spacing of lamps and lanterns can be reduced to achieve uniform illumination.

In general, it is hoped that the "batwing" of the "bat wings" will be able to achieve a wide Angle after the lighting.

The advantage of new style TEK LED panel light is obvious

Image
TEK  LED panel light , continue to use the reflective surface luminous technology, light after secondary reflection through high light transmittance mask projection, reduce glare, the light is more soft and comfortable to the human eye to watch not easy fatigue, particularly for students who have long time exposure to indoor lighting lighting, subway passengers or office staff. The application of the patented reflective material ensures the reflection efficiency of the light, and the original high light effect of the panel light is retained to the maximum extent. In order to guarantee the reliability of the use,   the design principle of TEK LED panel light  adhering to the "maintenance", improve heat dissipation performance, reduce the LED light failure of lights and lanterns, significantly prolong the service life of the lights and lanterns, saving the maintenance cost of lights and lanterns. TEK LED panel light is more intelligent TEK LED panel light can form a

What ways can see LED street lights to replace the high pressure sodium lamp?

Image
Under the condition of current technology,luminous efficiency of  LED street lamp  is more than high pressure sodium lamp, it is an indisputable fact that TEK LED street lamp can reach 160 LM/W. And HPS spectrum is concentrated in the yellow area, its color temperature is low, only 2000-2500 k, and relatively high color temperature such as LED, LED street light natural white temperature of 4000-5000 k, cold white is 5000-6500 k. At the same time compared with HPS, LED street lamp with high color rendering index, close to natural light in the actual lighting, can bring a person the sense of comfort. Followed by "irradiation uniformity", although the  LED street lamp  lighting is relatively concentrated, but can be by the light path of the second design, 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, so as to realize the uniformity of illumination.

TEK lighting: the advantages of LED solar street light

Image
Solar energy is already widely used in the world as a new energy source, and more and more technology products are being developed in favor of solar power. Among them, the street light is an essential infrastructure in the city's infrastructure, the city street lighting is very dependent on street lighting, but the daily and ordinary street lamp power consumption is very large, so the government is considering to improve people's lives and at the same time pay attention to energy conservation and environmental protection. According to observation, the street lamp on the pavement at present use about 60% of new type energy street lamp, of which 40% is  LED solar street light , there is no doubt that the future of LED solar street lamps market will be more and more hot. T he  advantage s of  LED solar street lamp 1，LED solar lamps use solar photovoltaic cells to provide electricity, and solar energy as a green and green energy source, "inexhaustible and
