LED spot lighting products were mainly produced to replace the traditional halogen spotlights. Restricted by the traditional light shapes, light heads and installation methods, the design works of LED spot lamps are harder. Within the range of existing spotlights size standards, it is difficult to make these lamps in high power consumption and high luminous flux. In the mean time, there are other design difficulties in light distribution, heat dissipation, electrical security, etc. Under such circumstances, the properties of long service life, high lighting efficiency cannot be fully expressed, which exerted a negative effect on the healthy development of LED spot lighting products.
LED is a new lighting technology. LED spotlights are one of the oldest LED lighting applications. It is necessary to draw up a new set of interface standards for them in accordance with LEDs’ properties. Lay out explicitly terms for product dimensions, modular blocks, electrical and optical parameters and interfaces, realize the modularization and interchangeability of LED spot lighting products and promote the development.
Presently, the international ZHAGA Union attracted hundreds of manufactures and industry enterprises from lighting, lighting source and LED module fields. The majority of them are from North America, Asia and Europe. ZHAGA Union was committing themselves to improve the LED lights modules and the compatibility of controls within machinery, tests and parameters. A large number of relevant technical specifications have been published and modified for several times.
As LED technology matures, costs reduces, LED lighting products has acquired an initial popularity. A lot of LED lamps have been applied in various occasions. However, the development and popularization of LED spotlights still faced with problems. How to solve the cooling problem of LED spot lamps with high power consumption and high luminous flux? How to realize the modularization and interchangeability? How to fully present the advantages of LEDs: long service life, high lighting efficiency, controllable, etc. In order to solve the cooling problem and the power supplier problem, many producers will design lamp shapes without following the IEC 60630 standard.
As the main force of interior lighting applications, LED spot lighting products were responsible for making people’s life brighter and more colorful. Producing lights which are more cost-effective and more reliable still needs endeavors of LED manufacturers.
