Introduction to LED Light Engine and ZHAGA Alliance

What is the LED light engine?

The LED light engine consists of an LED package (component) or LED array (module), LED driver, and an overall combination of other photometric, thermal, mechanical, and electrical components that are directly connected to the branch circuit through a conventional connector that matches the LED fixture. on. Therefore, the LED light engine is a device between the LED lamp and the LED lamp. The difference from the LED lamp is that it does not contain a standard lamp cap and cannot be directly connected to the branch circuit. The same point as the LED lamp can have a set light distribution. And cooling function. This product can effectively improve the stability of LED indoor lamps and improve various performance parameters (such as color rendering, system light effect, etc.), so it is the focus of future research and development and promotion of major LED lighting manufacturers.

What are the advantages of LED light engine?

1. Standardized manufacturing is conducive to the promotion of LED lamps.

At present, LED lighting fixtures are booming, especially indoor LED lamps are newly added by new companies every day, and new lamps are born. Therefore, the LED indoor lighting market is varied and has its own way, which brings great inconvenience to the standardized production and promotion of indoor LED lamps. Since the LED light engine is a standardized product, different LED lamp manufacturers can select different LED light engines to design and manufacture LED lamps according to different applications. Especially for new LED lighting manufacturers entering the market, just need to find several standard LED light engine products to design their own lamps, there is no need to worry about mass production, because the same standard LED light engine products can have Many manufacturers choose, and the standardized LED light engine products can be easily mass-produced.

2. Reduce the R&D expenses of LED lighting manufacturers and shorten the production cycle.

Traditional light source luminaire design only needs to involve optics and structure. However, due to the lack of standards for LED luminaire products, current LED lighting manufacturers need to deploy electronic, electrical, and heat-dissipation in addition to optical and structural professionals. Such as professionals, thus greatly increasing the burden on LED lighting manufacturers, and formed a high threshold for new LED lighting manufacturers, which is not conducive to the development of the entire LED industry. Therefore, how to effectively reduce the research and development costs of LED lighting fixtures and shorten the production cycle has become a major problem in the LED industry. With the standard LED light engine, the above problems can be solved. Since LED light engine products have considered electronic, electrical and primary heat dissipation and primary light distribution, LED lighting manufacturers only need to consider the structure of the lamp, secondary heat dissipation and secondary light distribution. Yes, which greatly reduces the development cost of LED lighting fixtures and shortens the production cycle.

3. Improve the overall performance of LED lamps (such as luminous efficiency, color rendering and color temperature), and improve the application quality of LED lamps.

Since the LED light engine clearly specifies the output lumens, color rendering index, system luminous efficiency, color temperature persistence, viewing angle width and other parameters of different applications, and the specified parameters are up to the highest level in the industry, the application of the LED lighting is improved. Quality has been greatly improved and effective protection.

ZHAGA Alliance promotes LED light engine

The European-based ZHAGA Alliance is an organization that standardizes LED light engine product standards and develops standardization of LED light engine product interfaces. Its purpose is to achieve interchangeability of lamps using different LED lamp manufacturers based on ZHAGA standard products. The continuous and rapid development of LED technology, ZHAGA standards cover the physical link, optical, electrical, light distribution, heat dissipation and other major links, and ultimately achieve the compatibility of products between different manufacturers in the ZHAGA Alliance. Change, replacement, etc., so if the country's LED regulations and standards focus on performance quality (such as: life, energy efficiency, color temperature and so on), then the ZHAGA Alliance solves the problem of interchangeability between manufacturers, such as Figure 1 shows:

figure 1

Therefore, as can be seen from the above diagram, the ZHAGA Alliance and the LED regulations and standards of various countries are complementary, and it is the mutual benefit of the chapter. The organic combination of the two will effectively solve the chaotic situation of the current quality and application of LED lighting products.

In addition, the establishment of the ZHAGA standard will help prevent the market differentiation of non-compatible optical engine products, so that LED lighting manufacturers can safely purchase compatible LED light engine products in the market. In addition, the establishment of the ZHAGA standard promotes technological innovation in the field of LED lighting applications, and enhances the overall efficiency of the LED lighting industry, helping the regulated and orderly LED lighting market.
