At this stage in LED lighting products, are used as the most direct and the application of the most simple way for replacement (include ball steep light and fluorescent tubes alternative). This relatively more easily be accepted. In addition, other than the energy conservation product appearance and effects are no apparent change. Of course, the lighting products more and more personalized today, lights and lamps and lanterns has gradually become the itself of the light quality indicators. But in a good many advantages, have LED, it will also has some not easy is widely accepted factors, such as glare and cost. For all the lamps and lanterns of more accustomed structure, because there are essentially in LED light source and the difference between the traditional (for example), so now directivity by the traditional structure of lamps and lanterns and coordinate, the characteristics of its own will be submerged in the lamps and lanterns of existing simple replace in.

        For a simple example: at present, exists on the market LED canister light and LED the ball steep light. In the cylinder in the need to place source, and to the traditional lighting is concerned, ball steep light had to belong to a light source. If corresponding to today's LED, ball steep light had to belong to a structure of lamps and lanterns. We need to think about the question is: when a LED ball steep light installation in traditional light tube mounted on the LED light source of ball steep light can be directly mounted on canister light structure of the form? The answer is yes. And, the cost effect is also LED ball steep light directly installation even better. But such application problem is, when a non-standard light source structure appear in front of consumers, consumers may not be the simple change, etc. In view of this situation, at present in manufacturing enterprise of light before a question is: what is a standard of the source of the light structure?

         We are given to this problem of the answer is: by packaging enterprise to light sources for the modularization and standardization. Only will LED light source for the modularization and standardization, and this work by the current packaging enterprise to finish, in the whole process, cost to replace will be optimum. The following several aspects from simply described in LED light source module in the process of outstanding advantages to replace.
