The lighting quality of outdoor spaces such as courtyards, courtyards, gardens, construction sites and parks directly affects

travel safety, site use experience and overall environmental perception. Traditional wired outdoor lamps have many problems,

such as complicated wiring, high reconstruction cost, great potential safety hazard of electricity consumption, single lighting

effect, etc. Therefore, solar projection lamps with no wiring, intelligence and low energy consumption have become the

mainstream choice for modern outdoor lighting and temporary lighting of projects. High-quality solar floodlights should not

only meet the basic lighting function, but also have high-quality lighting performance, durable structural performance,

all-weather environmental adaptability and simple intelligent control experience.

Relying on years of industry cultivation and technology precipitation, Guangdong Guangyun Lighting Co., Ltd. is a compre-

hensive high-tech lighting enterprise integrating product research and development, large-scale production, global sales and

professional after-sales. The company always adheres to the core business philosophy of "quality as the foundation and

customer as the center", and provides customers with high-quality photovoltaic lighting products and supporting solutions

with strict production standards and perfect service system. This paper systematically explains the professional selection

criteria of outdoor solar projection lights from five core dimensions.

First, lighting effects: value the global floodlight ability and reject local point lighting.

Some floodlights in the market have the problem of virtual standard parameters, such as narrow light distribution angle,

strong light convergence, limited lighting range and blurred lighting edge, which can only form local point light sources and

cannot meet the lighting needs of large-scale outdoor venues. High-quality solar floodlights are designed with large-angle

floodlight distribution, with uniform light distribution and wide irradiation coverage, which can realize soft lighting in the

whole site, completely eliminate the lighting blind area, give consideration to traffic safety lighting and overall site lighting

effect, and effectively solve the pain point problem of dim and uneven lighting in outdoor venues.

Second, structural material: high-strength hardware configuration, suitable for outdoor long-term working conditions.

Solar projection lights are deployed in the open air for a long time, and are subjected to sun, rain and wind erosion all the

year round. The quality of equipment materials directly determines the service life of the whole machine. Low-quality shells

are prone to yellowing, cracking, aging and embrittlement, and the failure rate of equipment remains high. High-quality solar

projection lamp engineering-grade material is resistant to high temperature, aging and corrosion, which is perfectly suitable

for outdoor complex and harsh working conditions; Tempered glass lens has high light transmittance, scratch resistance and

wear resistance, and is not easy to be atomized and yellowed after long-term use. It can maintain stable structural performance

and high-quality lighting effects for a long time under the scenes of sand erosion, heavy rain immersion and slight bump.

Third, protective performance: IP65 professional dustproof and waterproof, all-weather weather operation.

IP65 is the core weather resistance standard of outdoor solar floodlights, and it is not a formal parameter, which means that the

equipment has the professional protection ability of completely dustproof, spray-proof and waterproof. It can effectively block

the invasion of outdoor dust and sundries into the fuselage, and at the same time resist the erosion of heavy rain and the

infiltration of outdoor wet water vapor, fully protect the core components such as internal circuit boards, energy storage batteries

and LED light sources, and ensure that the equipment is always in a dry and stable running state. The equipment can be flexibly

installed on the outside of eaves, open-air walls, flower beds, open-air sites on construction sites and other open-air locations,

which can run stably all day, greatly reducing the failure probability and effectively prolonging the service life of the equipment.

Fourth, intelligent control: minimalist intelligent system, reducing the threshold for use.

Traditional outdoor intelligent lighting equipment generally has some problems, such as complicated operation, unstable signal

connection and failure of key control, which greatly reduces its practicability. High-quality solar floodlights optimize the intelligent

control logic, integrating one-button switch, timing and light-controlled automatic start and stop. The operation is simple and

intuitive, and the public can easily operate without complicated pairing and debugging and professional learning. Intelligent light

control system can automatically start and stop lighting according to the brightness of natural light in the environment, without

manual control, effectively eliminating problems such as ineffective power consumption and forgetting to turn off equipment, and

realizing intelligent and low-burden long-term use experience.
