Abstract

Aiming at the problem that the light emitted by the LED lamps especially the LED street lamps is axial and uneven in brightness, the invention provides an optical device of light distributor which can change the light emitting angle of the LED according to the requirements of the lamps; the light distributor has a whole structure, comprises a surface structure and parts, an internal structure andparts and a mounting structure and parts. The light distributor is characterized in that: the whole structure comprises a triangle curved surface structure (1), (3) with front and back symmetric, a structure (2), (5) which are bilaterally symmetrical. The structure (2) or (5) is an irregular raised and curved surface structure connected by two arcs of different radiuses; the light distributor effectively solves the problem of axial light during the application of the LED lamps, makes the passing through LED light beam uniformly projected in a specific directions, can obtain better light distribution curves of the street lamps for lighting, is very suitable for LED module source street lamps, has better economic benefits.

Description

technical field [0001] The invention belongs to a lamp fitting, in particular to a module-type packaged LED outdoor lighting street lamp fitting product. Background technique [0002] At present, with the maturity of LED chips and packaging technology, LED brightness requirements are sufficient to meet the needs of lighting levels, and LED solid-state lighting has become a trend. Energy saving, environmental protection, safety (low voltage drive), high color rendering index, and long life are the salient features of LEDs. In terms of application, especially in street lighting, the application of LED can give full play to its advantages of energy saving and environmental protection. However, the axiality of LED light emission is the biggest constraint on the design and use of lighting fixtures, and it is difficult to achieve an ideal light distribution curve for the lighting fixtures. This has become an urgent problem to be solved in LED lighting applications. Contents of...
