Yuannengji If the wavelength and color of street light LED light sources are consistent, it is difficult for manufacturers without LED spectrometers to produce products with pure colors. Leakage current LED is a unidirectional conductive light source. If there is a reverse current, it is called leakage.
The luminous angle of LEDs for different purposes is different. The price of special luminous angles is higher, such as the price of full diffuse angles.
1: Is the street light source bright and is the color temperature correct? It is very simple to distinguish whether the color temperature is appropriate. If it looks clear and bright, it means that the light source is better and the light efficiency is high. If it is not clear, you can stretch your palm to the side of the light source and look at the color of your palm. If it is ruddy, it means that the color temperature is just right and the color rendering is good. If the palm is blue or purple, the color temperature is too high.
2: The wavelength range of sunlight reaching the ground is about 300nm to 2600nm, while the effective wavelength range that has a positive effect on plant photosynthesis is about 400 to 700nm. The rate of green light from 520nm to 610nm being absorbed by plants is very low, so not all light is helpful for plant photosynthesis.
3: The light emitter of chip LED is the chip, and the price of different chips varies greatly.
4: Colloid The colloid of ordinary LED is generally epoxy resin. LEDs with anti-ultraviolet and fire retardants are more expensive. High-quality outdoor LED lamps should have anti-ultraviolet and fire retardant functions. The reliability design of LED lamps includes factors such as electrical safety, fire safety, applicable environmental safety, mechanical safety, health safety, and safe use time.
5: Products designed with non-toxic materials are expensive, especially indoor LED lamps. Don’t be greedy and choose LED lamps with odors. You can directly distinguish them with your nose. Products with odors are much cheaper than those without odors. Toxins such as lead, mercury, and cadmium require professional analysis.
6: The colloid of ordinary LEDs is generally epoxy resin. LEDs with UV resistance and fire resistance are more expensive. High-quality outdoor LED lighting should have UV resistance and fire resistance. Different designs are suitable for different purposes. The reliability design of LED lighting includes: electrical safety, fire safety, applicable environmental safety, mechanical safety, health safety, safe use time and other factors.
7: Products designed with non-toxic materials are more expensive, especially indoor LED lighting. Don’t be greedy and choose LED lighting with odors. Ներկայում, only a few LED manufacturers use non-toxic materials, which can be directly distinguished with the nose. Products with odors are much cheaper than those without odors.
