100w Street Light Housing Supplier Introduces How To Deal With


    The key problem of LED street light decay is temperature. LED street lamps generally fail in this link. Therefore, LED street lamp housing manufacturers have worked hard on the planning of heat dissipation substrate fins and heat dissipation modules. After assembly, they need to be outside the lamp heat dissipation module. Add baking varnish for maintenance to prevent weather corrosion. Next, follow the 100w Street Light Housing Supplier to understand how to deal with the problem of LED street light attenuation.

    1. Use the thermal conductive adhesive, the recommended soft ceramic thermal conductive adhesive. The soft ceramic thermal conductive adhesive for screen printing construction is different from the traditional laminated thermal conductive adhesive film. The soft ceramic thermal conductive adhesive is soft and semi-liquid. When the screen printer squeegee is applied to the aluminum substrate, the thermal conductive particles will penetrate into the pores on the surface of the substrate. I fill up to the full. In this way, a completely flat surface without pores will be formed, and the LED epitaxial substrate will be completely tightly bonded when bonded. In this way, the thermal resistance is reduced to a low level, and the heat can be quickly conducted out, which naturally reduces the ambient temperature of the LED die, extends the life of the epitaxial crystal, and greatly delays the onset of light decay. In addition, due to the ductility of the soft ceramic thermal conductive paint for screen printing construction, it will change with the thermal expansion and contraction of the aluminum substrate during high-temperature baking or reflow. The stress is very small, and it will not cause the aluminum substrate to warp or warp. Burst board.

    2. To deal with these existing problems, it is recommended that LED street lamp housing manufacturers start from basic information and deal with high-power LED heat sources from the inside out. For example, when the light-emitting component is bonded to the aluminum substrate, the thermal conductive adhesive plays a key role. Some manufacturers think that the thermal conductivity of the thermal conductive film or thermal conductive pad is better, and the film thickness should be as thick as possible, but the thermal resistance problem is not considered. No matter how good the thermal conductivity is, the thermal resistance of the film thickness is useless. What's more, the thermally conductive adhesive film or soft thermally conductive gasket cannot truly adhere to the substrate, and there are actually many pores on the bonding surface. These pores look like empty air pockets when viewed under an electron microscope, which is another way of thermal resistance. With so much thermal resistance that disturbs heat conduction, the power of heat dissipation and heat conduction is virtually reduced.

    3. In the external maintenance of LED lamps, it is recommended to use LED lamps soft ceramic heat dissipation paint. This spray-type soft ceramic heat dissipation paint can be directly sprayed on the outside of the LED lamps, and the construction operation is simple. It can be used to various shapes of heat dissipation structures, and it can also be adjusted to different colors to meet the needs of landscape planning. The soft ceramic particles in the spray-type heat dissipation paint are nano-processed. The fine particles are not only easy to operate with the spray gun, but also make the thermal conductive particles on the same coating area more and densely distributed, and the area for the temperature to evaporate and diffuse becomes larger. Let the heat energy of the LED lamps be conducted quickly. The soft ceramic heat-dissipating paint is classified as a thermosetting material, which conforms to RoHS environmental safety standards. The construction procedure is simple and does not require any special equipment. After baking, it can be thermoset to accept the high temperature of the LED for a long time without mutation. LED street lights, landscape lights, or LED advertising billboards used in the field will also face acid and alkali damage such as wind and rain, acid rain, bird droppings, air dust, black smoke emission hELlip; and so on. Therefore, this spray-type soft ceramic heat dissipation paint must have the characteristics of acid and alkali resistance. The current acid and alkali resistance fluctuates between PH3~11, which can effectively maintain the appearance of LED field lamps from corrosion.

    The cost structure of the LED street lamp housing follows the development of packaging technology, carrier board planning, and heat dissipation module structure. The quality continues to improve, and the cost also decreases with the development of technology and market demand. Therefore, LED street lamp housing manufacturers need to reduce costs, improve quality and increase profits from an innovative perspective.
