YUANNENGJI Cracks caused by thermal expansion and contraction and internal stress are all caused by the outer shell. If a material with a water outlet is selected, if the design and production process are unreasonable, a large internal stress will be generated. Experienced landscape lamp manufacturers will choose constant temperature protection during injection molding, and many physical methods can be used to eliminate internal stress.
For outdoor lamps, waterproofing and dustproofing are the top priorities. Short circuit of lamps is a fatal blow to the product and a very big hidden danger to the people around. Outdoor landscape lamps are exposed to wind and sun all year round, so anti-aging is very important. The external PC cover and internal glue of the lamp affect the life of the product. Poor quality PC cover and glue will change color over time, affect the color of the light, and emit uneven light.
LED landscape lights have many advantages, such as energy saving. LED lamps with the same light efficiency save more than 80% energy than incandescent lamps and more than 50% energy than energy-saving lamps. The service life is also long. The service life of LED light sources can reach 50,000 to 100,000 hours, which is more than 10 times that of traditional light sources.
1: Pay attention to the shelf life: The heat dissipation effect of the lamp is closely related to the life of the lamp. If the heat dissipation is not done well, the internal accessories are prone to aging and burning. Therefore, when purchasing lamps, pay more attention to its structural design, the effect of glue on heat dissipation, and reasonable and effective heat dissipation design is also an improvement in product quality.
2: Check the luminous effect. For good lamp products, excellent luminous effect is a necessary condition. The luminous effect is relatively obvious, whether the luminous effect is uniform without faults, whether the light color is pure without color cast, and whether the irradiation range is uniform without light spots.

4: LED landscape lights are highly ornamental and illuminating, more energy-efficient and longer-lasting than traditional light sources. The simple shape reflects the design concept of popular light poles, uses digital color lamps, and uses intelligent digital controllers to achieve color chasing, scanning, gradient, flashing and other effects, with strong environmental protection effects. LED landscape lights must not only have good lighting effects, but also have many colors. We are in tourist parks and some tourist attractions. When night falls, all LED landscape lights are lit up, colorful and beautiful! Street lights only need one color for lighting.
5: Pay attention to the light decay problem when using. Although many LED products indicate that the luminous life is more than 100,000 hours, they may not have such a long life in current actual applications. The reason is that LED has a light decay problem. Once the LED luminous brightness drops below 30% of the original brightness, aging, breakage, yellowing and other phenomena will occur.
