The solar LED street light buyer must pay attention to the matter
LED outdoor lighting lamps and lanterns classification is more, solar LED street light have solar panels and batteries, other such as chips, light pole, power and installation is the same, so this article use solar LED street light as the example for buyers to introduce some matters need to be aware of when buying.
The chip.
LED chip is divided into domestic and imported, such as OSRAM and CREE chips are imported, good stability and long warranty time, domestic brands such as Epistar, cheaper price. The same lamp to select different chip price is different also, so buyers when buying LED street light must ask manufacturer general standard is what kind of chip, the price difference how many. If you pay domestic chip with the imported chips price, that is a disadvantage.
Color temperature.
Solar LED street light usually have a color temperature of 3000K-6500K, How to choose color temperature is based on different use environment. If used in garden, usually warm white (2700-3500K), Fast road and main road with cold white(6000K-6500K); Neutral white is Wide range of use.
Communicate with factory if you don't know, manufacturer's technical personnel usually give more professional advice. you has asked to color temperature, can also be specific consultations.
Power.
LED street light beads have single 1W, 2W, 3W, and combine the number of particles used to calculate power.The choice of the power of the specific lamps depends on the width of the road, the arrangement mode, the installation height and spacing of the lamps and lanterns, You can consult a designer.
Illumination.
When it comes to illumination, the light flux and luminous flux = luminous efficacy* power, with the highest luminous flux is6500K under the same conditions, the lowest luminous flux of the color temperature is 2700K.The illumination is the luminous flux received per unit area, the unit Lux.
Such as 20W lamp in 6 square meters , you may feel more bright, but if put within 60 square meters of environment, may be darker, so luminous flux and intensity of illumination need, specific environment, nature is also different.
A little professional customers often put forward specific requirements, if new buyers don't understand these data, large manufacturers usually have simulation software, can be based on specific circumstances, such as road data simulation parameters such as the intensity of illumination.The new type of light distribution design takes into consideration the vertical and direct illumination of the pedestrian in the road, making the road surface lighting wider and the surface illumination uniformity is better.
The configuration of solar LED street light.
Solar LED street light are mainly made up of solar panels and supports, solar cells, accumulators, controllers, light lines, lamp holders and lamp posts.The selection of solar panels and batteries depends mainly on the sunshine value of the area, and the light time of the rainy day is based on the environmental requirements.
lamp post.
Normally clients to buy the LED street light is the most attention is the chip quality of lamps and lanterns and power factors, rarely consider the light pole, but in fact the heigh quality is also very important, don't know whether you seen some on the way to use fixed number of year long street lamp light pole decay, some manufacturers in order to reduce cost, make the light pole although cheap, but on the quality and use fixed number of year certainly not good light pole.
Good light pole is generally more thick, good light pole material, spraying process improvement, 50 years does not rust, so customers buy light pole, don't always see only some factory price cheap how much light pole, but from the aspects of price, process quality into account.
