Abstract

The invention provides an optical device, namely a light fitting with a light distribution device capable of changing the lighting angle of the LED and functions thereof, which aims at resolving problems that an LED light fitting, especially the light of an LED street light fitting emitted by an LED has axial property, thereby causing uneven brightness to the light of the light fitting. The light fitting comprises a light fitting casing, a light seat, a large power LED module light source, a reflector light cup, a light cover and a lens, and is characterized in that the large power LED module light source is connected with the light distribution device, which efficiently resolves the problem of light axial property in the application of LED light fittings, thereby enabling LED light beams to be emitted towards special directions via an even light type, and obtaining relatively perfect light distribution curves for lighting to the street light. The light fitting with the light distribution device is extremely adaptable to LED module light source street lights, and has better economic benefit.

Description

technical field [0001] The invention belongs to a lamp, in particular to a module-type packaged LED outdoor lighting street lamp 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 the invention ...
