What determines the quality of LED tunnel lights?

LED street lights consist of five main components: lamp post, light source, battery, solar panel and controller. It is a solid cold light source, with environmental protection, no pollution, less power consumption, high light efficiency, long life and other characteristics, therefore, LED tunnel lights will become the best choice for road lighting energy-saving transformation. LED tunnel lamp is an efficient solid-state light source formed based on semiconductor PN junction that can emit light with weak electric energy. Under certain forward bias voltage and injection current, the holes injected in P-zone and the electrons injected in N-zone are diffused to the active region and then combined with radiation to emit photons, converting electric energy directly into light energy. It also requires accessories such as cages, wires and solar panel brackets.

Under certain forward bias voltage and injection current, the holes injected in P-zone and the electrons injected in N-zone are diffused to the active region and then combined with radiation to emit photons, converting electric energy directly into light energy. To know whether the quality of LED tunnel lights is good, we can judge led tunnel lights based on the LED lamp post, panel and battery as well as their light source and controller light components.

The first LED lamppost

LED tunnel light poles are divided into hot-dip galvanized and cold-galvanized. Is hot dip galvanizing or cold galvanizing better for LED tunnel light pole? Anti-corrosion: hot dip galvanizing is dozens of times cold dip galvanizing; Hot dip galvanizing is to immerse the whole LED light pole into a hot dip galvanizing solution of 450-480 degrees, and cold dip galvanizing is to electroplate the light pole at room temperature; Thickness of galvanizing layer: the thickness of hot-dip galvanizing LED lamp is much greater than that of cold galvanizing; Appearance finish: cold galvanized light pole is smoother and more beautiful than hot galvanized light pole; Adhesion: Cold galvanized light poles have less adhesion than hot galvanized light poles. Lead lamp posts must be hot-dip galvanized plastic products. Although the price of an entire hot-dip galvanized molded LED light pole is much higher than that of a cold-galvanized light pole, it is cost-effective in terms of practical application and service life.

Second: solar panels

The quality of the LED tunnel light solar panel can be seen with the naked eye. We can check the tightness of the panels, the details of the process, as well as the thickness of the toughened glass and the quality of the aluminum frame, but the power of the solar panels can only be tested by instruments. To save costs, some unscrupulous traders use poor quality steel and glass and thin aluminum frames as fixtures for solar panels. This kind of street lamp solar panel is easy to be damaged during transportation, and it is not easy to encounter hail and rain during use, so be careful when choosing solar panels. There are also bad enterprises that use bad batteries, low conversion efficiency, poor power generation and quality, and the possibility that the battery has no voltage after a period of use. We must pay attention to these when buying solar panels.

Third: Battery

LED(light-emitting diode) street lamp battery need to choose high quality lithium battery or colloid battery, with a certain capacity of the battery has the corresponding weight, can be used for LED(light-emitting diode) street lamp battery weighing, the weight difference is too large, can not choose. The battery surface is labeled with any manufacturer's name and capacity.

Fourth: LED light source

LED tunnel lights use LED light pearlescent effect is very important. Although some LED beads can achieve certain wattage, they often do not achieve light efficiency. When choosing, should choose LED lamp bead, good lamp bead can improve light effect, reduce light decay, and has high color rendering.
