What is the working principle of LED solar street lamp?

LED solar street lamps can be seen in the streets of every major city, but we know little about its working principles. In fact, that is very simple, and it is this great invention that makes our city more environmentally friendly.

First, let's take a look at the composition.
LED solar street lamps mainly consist of solar cell components (monocrystalline silicon, polysilicon), component support, light source, controller, battery, lamp, etc.

And how does the LED solar street lamp work? 
LED solar street lamps use Photovoltaic effect principle to do solar cells, solar panels during the day to receive solar radiation and translated into electricity output, after stored in the storage battery charging and discharging controller, the night when the intensity of illumination is gradually reduced to about 10Lx, solar panels voltage of 4.5 V, LED solar street lamps controller to detect the voltage value of the action, battery for light source discharge, battery discharge after setting time, controller action, battery discharge end.

The solar panel of LED solar street light has a high efficiency of 127Wp/m2, which is very beneficial to the wind design of the system.With the led lamp holder part bead welding on aluminium substrate, arranged for a certain distance between lattice as a plane light source, the general light source according to the type of controller is divided into 3 strung together, string together the 3, 6, 10 frequently used.

The control box body is made of plastic, beautiful and durable.
Control the box for the maintenance of lead-acid batteries.The system chooses the valve control sealed lead acid battery, because its maintenance is very little, so it is called "maintenance battery", which is beneficial to the reduction of system maintenance cost.The controller is designed with a combination of functions (including light control, time control, over-charge protection, over-discharge protection and reverse protection, etc.) and cost control, achieving high cost performance.

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.

Rule of thumb: what are the installation instructions of DALI LED high bay light?

Image
DALI LED high bay light , also known as LED warehouse light, mainly used in factory workshop, warehouse, exhibition hall, etc., have gradually entered homes, because it is using the latest LED lighting energy saving technology, high reflectivity, high power, high utilization rate of light source. But good lamps and lanterns need specification installation, to highlight its advantages, below for everyone to explain the DALI LED high bay light installation: 1，Define DALI LED high bay light installation height according to the lighting environment, because the environment will change the reflection efficiency of lamps and lanterns. Usually the height of DALI LED high bay light  should be above 5 meters, thread is not close to the lamp shell. If installation height is less than 3 meters, protective measures must be taken to prevent a vehicle to touch. 2，TEK DALI LED high bay light protection class is IP65, choose waterproof transformer, chip packaging place with high temperature resi
