High-power LED light source casting process
As a new type of light source, LED is a pioneer in replacing traditional lighting with LED. It not only breaks through the original application field, attracts stronger attention, but also brings unlimited business opportunities and reverie to the industry. As a lighting source, it has the advantages of small size, low power consumption, long life, fast response, safe and low voltage, good weather resistance, good light control effect, etc. It is mainly used for outdoor landscape, wall advertising, inside and outside buildings, large buildings , large bridge guardrails and wall projection lighting.
In fact, in the application of high-power light sources, there are two prominent problems: First, it is difficult for lamp manufacturers to waterproof the shell. When the product is used outdoors for a long time, due to the aging of the sealing components, there will be tiny gaps between each other. At this time, water vapor can easily penetrate into the interior of the product, causing damage to the light source product. The gas inside the lamp will also generate a certain pressure in different temperature environments, which also accelerates the failure of the sealing performance of the product. Therefore, it is not long-term to solve the waterproof problem of LED high-power light sources through external waterproofing. Second, the high-power heat generation is high, and the light decay of high-power light source products is relatively large under high temperature conditions. However, in order to solve the waterproof problem, non-conductive glue has to be used as the sealing body of the light source, which will make the LED light source in a shorter time. expires within the time period.
In order to achieve the light-emitting angle, the traditional method is to adopt the split design of the light source and the secondary optical lens, and change the light-emitting angle of the light source by changing the secondary optical lens, but the gap between the light source and the lens will easily enter the dust, affecting the luminous flux output. When used outdoors, water will enter between the light source and the lens, changing its luminous angle, and at the same time deactivating the light source. Multiple production and assembly increases material and labor costs.
In this context, the technical research on the casting process of LED light source has been started. Through the independent research and development of LED light source product sealing body full-package integrated structure design, the development of blended modified materials, and the one-time molding casting process, the light source can be waterproof, Dust-proof IP68 protection grade, with excellent performance such as high and low temperature resistance, UV resistance, integrated high-power light source, etc.
The high-power light source using the casting process solves the problem that the traditional method cannot make the light source have a luminous angle due to process limitations, and can also solve the problem of dust and water entering between the lens and the light source due to the split design of the optical lens and the light source, affecting the luminous efficiency and the light source. At the same time, the secondary packaging process can solve the damage of the light source caused by water ingress and reduce the production cost. It can be widely used in high-rise buildings, tower bridges and other architectural lighting places, and can also be widely used in various occasions with harsh conditions. Such as: underground landscape lighting of squares and parks; underwater landscape lighting of swimming pools and lakes; landscape lighting of fountains and waterfalls, etc.
