Problems solved by technology

Existing LED lighting devices mostly use optical lens type light distribution or reflector type light distribution, but once the optical lens or reflector is fixed, the light distribution curve and light field distribution will be fixed. Therefore, different lighting devices need to To do a different design, which increases the production cost

Description

technical field [0001] The invention relates to a light-emitting module, in particular to a light-emitting module capable of changing light distribution curves. Background technique [0002] With the development of semiconductor lighting technology, light emitting diodes (Light emitting diodes, LEDs) have continuously improved light efficiency, and are now gradually replacing traditional light sources, especially in the field of street lights. A new type of light-emitting diode can be found in the article "Illumination With Solid State Lighting Technology" in IEEE Journal on Selected Topics in Quantum Electronics, Vol.8, No.2, March / April 2002 by Daniel A. Steigerwald et al. How to effectively distribute the light energy emitted by LEDs is a key problem to be solved in the design of LED street light optical systems. Most of the lighting areas formed by the current LED street lamps are circularly symmetrically distributed. In order to save energy and realize lighting in a la...
