Street lamp lighting technology from the last century 30's of the fluorescent low pressure sodium lamp develop to 60's of the high pressure mercury lamp and high pressure sodium lamp, already has no big innovation more than 40 years．
the last century 30's the last century 60's the present century
pressure sodium lamp sodium lamp
In this situation, the lighting manufacturer adopted the following strategies:
1. Continually to supply new products, old products on appearance style innovation, To extend the product from maturity to decline stage of life cycle;
2. Step by step into a new market segment of street lamp, such as tunnel, Subway etc;
3. Introduce a new revolutionary product, such as LED, to meet the new growth.
But, the development of LED street lighting is uneven, the reason is:
1. The performance of LED is under developing;
2. The technology in the hands of minority within the semiconductor company, the street lighting manufacturer can not refer to the development experience from another way, LED technology is likely to become the Pandora's box of the enterprise.
