Superior LED Light Engine - Indoor LED Lighting Application Booster

　　 Limited to time rush, and I have limited knowledge, it is inevitable that there will be regional and inadequacies in personal opinions. Please readers and experts to correct and criticize the axe.

First, LED light engine (LED light Engine)

The LED light engine consists of an LED package (component) or LED array (module), an LED driver, and an overall combination of other photometric, thermal, mechanical, and electrical components that pass through a conventional connection that matches the LED fixture. The device is directly connected to the branch circuit. 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.

Second, the promotion 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 lighting 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. For example (Fig. 1) is an LED light engine used in indoor LED downlights by Tridonic Lighting Electronics (Shanghai) Co., Ltd. Its parameters are: color rendering index >90, output lumens 1100 -4000lm, color temperature constant MacAdam 3 SDCM,

System luminous efficiency > 65 lm / watt, color temperature range 2700 K − 6500 K, life > 50,000 hours, dimming range 1% * to 100%, is an LED light engine product suitable for commercial lighting LED indoor lighting applications.

Figure 1 ZHAGA Alliance pushes LED light engine

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 mission is to achieve interchangeability of lamps using different LED lamp manufacturers based on ZHAGA standard products. In addition, in order to cope with the continuous and rapid development of LED technology, the ZHAGA standard covers the main dimensions of physical dimensions, optics, electrical, light distribution, heat dissipation, etc., and ultimately the products between different manufacturers in the ZHAGA Alliance can achieve mutual Compatible, interchangeable, replacement, etc.

The establishment of the ZHAGA standard will help prevent market differentiation of non-compatible optical engine products, enabling LED luminaire manufacturers to purchase compatible LED light engine products on the market with confidence. 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.

The ZHAGA Alliance is an open organization where members can share IPR intellectual property rights and open companies in the lighting industry. Members of the organization include LED light engine product manufacturers and LED luminaire manufacturers, as well as component suppliers such as heat sinks and optical components. TRIDONIC is one of the main members of the ZHAGA Alliance.
