Install and use
The project-light lamp can be installed and used individually, or multiple lamps can be combined and installed on a pole above 20m to form a high-pole lighting device. In addition to the beautiful appearance, centralized maintenance, and reduction of lamp poles and floor space, the biggest advantage of this device is its strong lighting function. When the light is projected from a high place, the spatial brightness of the environment is high, and the light coverage is large, giving people a feeling similar to daylight, so it has high lighting quality and visual effects. In order to meet the minimum safety performance requirements for outdoor use, the enclosure protection level of the floodlight should be IP×3 (open type). In order to improve the durability of the lamps and reduce the maintenance workload, people are paying more and more attention to the development of closed floodlights with a higher one-time investment cost, and the enclosure protection class is IP55.
In order to further improve the light output ratio of lamps, reflectors tend to adopt block surface reflectors that help reduce light blocking and multifocal reflectors that meet special lighting requirements; the surface treatment of reflective surfaces tends to adopt new materials and new processes. To obtain a reflectance of more than 96%.
In order to reduce the weight of the lamp and reduce the consumption of metal materials, the lamp shell will be developed in the direction of high temperature resistant, high mechanical strength, and anti-aging plastic shell.

Atmosphere lighting in bars, dance halls and other entertainment venues.
Application place
1. Building exterior lighting
Projecting a certain area of the building is nothing more than the use of round and square-shaped projection lamps that control the beam angle, which is completely consistent with the concept of traditional projection lamps. However, due to the small and thin LED projection light source, the development of linear projection lamps has undoubtedly become a highlight of LED projection lamps, because many buildings simply do not have a place to place traditional projection lamps. It is easy to install, can be installed horizontally or vertically, and better integrates with the building surface, bringing new lighting vocabulary to lighting designers and expanding creative space. And it will have an impact on the lighting techniques of modern buildings and historical buildings.
2. Landscape lighting
Unlike traditional lamps, LED floodlights are mostly glass bulbs, so they can be combined with urban street furniture. It can be used for lighting in urban leisure spaces such as paths, stairs, decks, waterfronts, and gardening. For flowers or low shrubs, you can use LEDs as a light source for lighting. LED hidden cast light fixtures will be particularly favored. The fixed end can be designed as a plug-in type, which is convenient for adjustment according to the height of plant growth.
3. Signs and indicative lighting
Places that require space limitation and guidance, such as the separation display of roads and pavements, local lighting of stair steps, and emergency exit indication lighting. You can use led floodlights with appropriate surface brightness to self-illuminate buried lights or embedded in vertical walls. Lamps and lanterns, such as ground guide lights in the auditorium of theaters or indicator lights on the side of seats, and guide lights on floors in shopping malls. In addition, compared with neon lights, LED floodlights have low voltage, no fragile glass, and will not increase costs due to bending during production. They are worthy of promotion and use in logo design.
4. Indoor space display lighting
As far as lighting quality is concerned, because LED floodlights do not have heat, ultraviolet and infrared radiation, they will not cause damage to exhibits or commodities. Compared with traditional light sources, lamps do not require additional filter devices, and the lighting system is simple, low-cost, and easy to install. . Its precise lighting can be used as a substitute for optical fiber lighting in museums. Commercial lighting uses colored LEDs in metropolises, and interior decorative white LEDs combined with interior decoration provide auxiliary lighting for the interior. LEDs can be used for hidden light bands, which is particularly advantageous for low spaces.
5. Entertainment venues and stage lighting
Due to the dynamic and digital control of color, brightness and dimming of LED floodlights, lively saturated colors can create static and dynamic lighting effects. From white light to any color in the full spectrum, the use of LEDs opens up new ideas in the lighting of such spaces. The maintenance value of long life and high lumen (90% luminous flux is still maintained after 10,000 hours), compared with the 50-250 hour life of the metal halide lamp, reduces the maintenance cost and the frequency of light source replacement. In addition, the LED floodlight overcomes the color shift of the metal halide lamp after a period of use.
