In-depth Demand Report | Disassembling Best Solar Floodlight

LED street lamp serious droop problem, need to solve fundamentally from LED heat dissipation technology. LED street lamp serious droop, leading to install in less than a year of certification acceptance of LED street light can't through the use of units. As for the LED street lamp serious droop 'from the root of the LED heat dissipation technology is needed to solve.
LED road lighting failure causes of
temperature is actually LED road light failure, the key problem of LED street lamp must stuck in this link. LED lights because light power is greater than the household lamps and lanterns, so manufacturers in the cooling plate fins, the design of the cooling module so painstakingly, assembly should be on the outside of the lamps and lanterns of the cooling module, and protected from weather erosion of the lacquer that bake. But the external protection of paint to the heat of the heat dissipation module and sealing the back, lead to bad heat dissipation LED epitaxial droop.
glow LED epitaxial heat belongs to the small scale of concentrated heat, application in high power lamps, power input power is big also, LED the interface temperature is quite high, under the street light long time continuous work, such as the heat dissipation module not effective heat dissipation, can affect the service life of the LED and light, LED street lamp serious as current light failure is caused by these factors. LED street lamp is used outdoors, interference factors with environmental climate, so most of the manufacturers is to LED street lamp radiator shell with anode protection, or spray paint, in order to avoid the erosion of acid and alkali substances. Anodization of life is not long, time is a bit long or oxidation discoloration, if you want to remove the heavy industry, not only time-consuming and labor will increase maintenance cost; Paint protection cost is low, the effect of protection, but generally no cooling function of the lacquer that bake, paint body itself will form the blocking effect, and then increase the LED street lamp radiator thermal impedance, not only did not help, but because the heat sealed inside the radiator, LED power reduction, and finally leads to serious droop. The above has been in the LED lamps and lanterns industry exist serious problems, almost is the public acceptance of LED street light cannot pass procurement unit.
LED road lighting failure solving Suggestions
to solve these existing problems, Suggestions street lamp manufacturers, starting from the basic material of fundamentally by inside and outside of solving the problem of high power LED heat source. For example, in the light emitting component and aluminum substrate bonding, heat conduction glue can play a key role, some manufacturers think thermal conductive film or coefficient of thermal conductivity of thermal conductive rubber gasket is better, the film thickness is as thick as possible, don't want to thermal resistance. Met again good thermal conductivity, thermal resistance of film thickness. And thermal conductive film or soft thermal conductive gaskets, and not the real and substrate or joint surface in fact there are many pores. These pores under the electron microscope to watch, like empty air pockets, which is another form of thermal resistance. Under so many interference heat conduction thermal resistance exists, the efficiency of heat dissipation of thermal conductivity virtually was decreased.
with lower thermal resistance of thermal conductive adhesive, recommended construction of screen printing soft ceramic thermal conductive adhesive. Construction of the soft screen printing ceramic thermal conductive adhesive is different from the traditional joint type thermal conductive film, soft ceramic heat conduction glue is soft and half liquid in a screen printing machine blade coating on aluminium substrate, the thermal conductive particles can penetrate into pores on the surface of the substrate and to fill to the full. This will form a complete flat without pore surface, and LED epitaxial plate bonding will be completely closed. Thus reduce the thermal resistance to the lowest degree, heat can be conducted away quickly, reduces the temperature of the LED grain, naturally also prolongs the service life of epitaxial and significantly delay the onset of droop. Moreover due to the construction of the soft screen printing ceramic thermal conductive paint is malleable, baking at high temperature or back to welding, will change together with the aluminum plate heat bilges cold shrink, stress is very small, not cause aluminum substrate warpage, more won't explode plate.
to protect the outside of the LED lamps and lanterns of LED lamps and lanterns is recommended for the soft radiating ceramic paint. The spray type soft ceramic thermal spray paint can be directly on the external LED lamps and lanterns, operation is simple, can adapt to various shapes of the cooling structure, can also be adjusted to different colour, according to the demand of the landscape design. Spray type radiator paint inside the soft ceramic particles, is through nanoscale chemical processing, fine particles is not only easy to spray gun, also let the same coating area of the thermal conductive particles on the more and crowded, make temperature volatile through the area of the loose is bigger, make LED lamps and lanterns, heat conduction out quickly. Soft radiating ceramic paint type belongs to thermosetting material, meet the RoHS environmental protection safety specification, construction procedure is simple and without any special tools, after baking hot setting, but for a long time under the high temperature of the LED will not have a qualitative change. Used in outdoor LED street lamp, landscape lamp or LED advertising billboards, also will face the wind and rain, acid rain, bird droppings, dust and smoke emissions hELlip; And so on of acid and alkali. So this kind of type soft radiating ceramic painting must have the characteristics of acid and alkali resistance, the resistance to ph range in PH3 ~ 11, can effectively protect the LED outdoor lamps and lanterns is not eroded appearance.
the cost of the LED lamps and lanterns as encapsulation technology, loading board design, heat dissipation module structure material development, and continuously improve quality, cost, too, as the technology development and market demand. But investment in material improvement, there are few manufacturers and this is mainly on the development of industrial and commercial behavior related to Taiwan. Taiwan manufacturers than process and design, research and development on the basis of the material less weight. So in solving technical problems, or reduce the cost issues, such as preferred procurement or production management thinking. But Japan manufacturers points in the first time, can think went up from applied materials, from the Angle of innovation to reduce costs, improve quality and increase the profit.

Now many of the new industry has been rapid development, in order to satisfy the demands of the actual use of the modern people's life, now the solar street light, has obtained the promotion and popularization use effectively, under the street lamp use, can effectively save the electric energy consumption, therefore, meet the actual needs of the development of modern energy-saving technology, the LED solar street light, is one of the more popular products, so how to choose the LED solar street light manufacturer.


now many cities and regions in the process of construction, will mainly consider the use of LED solar street lights, LED solar street lamps are chosen in the process, the manufacturer of the understanding is very important, because only professional manufacturer, can produce qualified products, superior performance of solar street lights, the current domestic manufacturers more solar street lamps, is a real professional manufacturer is very few, how to choose the professional manufacturers, become a problem we focus on, can be seen through the observation, want to choose the real manufacturer of LED solar street lamps, also need to understand from each aspect.


in the process of to actual manufacturer to understand, the first thing to watch factory production scale, technology level, the quality of products, etc. , these are very important, LED solar street lamps mainly divides into five parts, including street lamp lighting, solar panels and batteries, controller, LED lamps and lanterns, can be seen through the actual understanding of the professional manufacturers, the lights in the manufacturing process, to the requirement of every link is very strict.


through the actual understanding, you can see that when choosing a solar street lamp, for the choice of LED solar street lamps factory, is very important, only a professional manufacturer to produce LED solar street light, in use process to play their own advantages, if you choose the inferior solar street light, although the price is low, but in use process will appear many faults and problems, affects the efficiency in the process of actual use, can also lead to rising later use of the cost of maintenance.

Nowadays market competition in the solar street lamps, is no longer a single competition in product quality, in the final analysis is the talent and the team's competition, because of the need to produce a good product basically still want to rely on people, so a lot of solar energy street lamp manufacturers to build a team, give top priority to personnel training and team building. The personage inside course of study points out that the recruitment is just the tip of the iceberg for human resources, in addition, also include how to & other; Education & throughout; 、“ Retention & throughout; 。
solar street lamps factory the right talent and team work for solar street lamps factory is large, the effect of start-ups and production-oriented enterprises, in particular, it is important to every link. Keep the solar street lamps factory personnel and team stability is essential to enterprise's development, and every aspect of business need talent and team collaboration with each other, forming a common progress of the whole.

With the rapid development of national economy, the expansion of cities, a and a road was completed, the demand of street lamp is bigger and bigger. And LED technology matures, laying off makes the traditional high pressure sodium lamp lights, LED lights for road lighting


with the rapid development of national economy and the expansion of cities, a and a road has been built, the demand for street lamp is becoming more and more big. As light-emitting diode technology matures, the traditional high pressure sodium lamp has been knocked out, the light emitting diode lamp has become the first selection of road lighting. Now, LED street light penetration rate is increased year by year, I believe that a few years later, it will appear in every way. So everyone must be very curious why the LED street lamp is so popular, what are its advantages? No defects? Today, LED street lamp manufacturers will take you to simply understand the advantages and disadvantages of it. It is well known that the LED street lamp differs from traditional street lamps in the street lamp head. Traditional street lamps using high pressure sodium lamp cap, and leds lamps using led street lamp. Light emitting diode lamp advantages: 1. High lighting efficiency. Leds lamps in the form of secondary optical design, the light energy is concentrated in the designated area. 2. Light attenuation is very small. Light emitting diode light attenuation is small, light attenuation per year on average less than 3%. Even after 10 years, it still has very high use value. 3. Long service life. It can be used more than 50000 hours. 4. Energy conservation and environmental protection. The energy required for the same lighting effect less than a third of the high-pressure sodium lamp. Light emitting diode lamp shortcomings: 1. Although led street lamp light attenuation is low, but compared with the high power led street light, small power led street lamp light attenuation are still high. 2. 2 the color of the light. Led street lamp is generally white. Due to manufacturing defects and the lens match error, will produce yellow aperture, affect the whole lighting effect. In short, everything happens for a good side, the advantages outweigh the disadvantages of led street light, in many ways than the traditional high pressure sodium lamp, so it is very popular with the people and penetration are rapidly improving.
