The projection lamp can not only be installed and used alone, but also be composed of multiple lamps, which can be centrally installed on the pole above 50m to form a railing lighting device. In addition to the characteristics of beautiful design, centralized maintenance, reduced street lamps and land occupation, one major advantage of this kind of equipment is the strong lighting effect. When light is projected from high altitude, the indoor space of the natural environment is brighter, and the light covers a large area, giving people a feeling of nearby daylight, so it has higher lighting quality and visual impact. In order to consider the safety factor at least when used in the field, the enclosure grade of the floodlight should be IP × 3 (open). In order to improve the durable and practical characteristics of lighting fixtures and reduce the amount of protection and maintenance labor, we pay more and more attention to the development trend. Closed floodlights with high one-time project investment cost have an enclosure grade of IP55.

In order to further improve the light output ratio of lamps, waveguides tend to choose block surface waveguides that are beneficial to reducing the light shading of lamp sources and multi focus waveguides that consider the provisions of lighting fixtures; The surface treatment of the vertical surface tends to choose new materials, new technologies and new processes to obtain a reflectance ratio of more than 96%.

The installation method of LED projection lamp is the same as that of general projection lamp, but it is not simple to install it according to the specified detailed process, so I'll let the projection lamp manufacturer teach you how to install LED projection lamp. Installation process of LED floodlight: ensure that the lighting fixtures are intact. In order to better ensure the service quality after installation, the LED floodlight manufacturer proposes to conduct a detailed inspection of the LED field light commodities on site before installing the LED floodlight.

Try to check whether the external view of the LED projection lamp is damaged, and whether all parts and accessories are complete, so that the lamp has the problem of production and quality and can have after-sales maintenance services. And each item needs to be carefully checked during the inspection. After the appearance of all lighting lamps and accessories is not damaged and their parts and accessories are complete, it is necessary to do a good job in the installation preparation of lighting lamps and lanterns, which should first be in accordance with the installation engineering drawings attached to the processing plant, First, organize the installation staff, and try to connect a lot of floodlights to see whether the installation engineering drawings are appropriate. If there are standards that can be assigned to test light one by one, so as to prevent the damaged ones from being removed and replaced after installation at the installation site. In addition, it is also necessary to prepare in advance the tools and raw materials that must be used in the important links in the whole installation process.

In that way, it can be ensured that even the floodlight with wiring short-circuit fault will not be burned after the switching power supply is turned on. The floodlight manufacturer suggests that the position must be ensured, and there is no need to be lazy. After all the tests are done, it should be lit as much as possible for a period of time, and the next day and the third day should be followed up. After that, it is full of good, and generally there is no simple problem behind it.
