Embodiment Construction

[0044] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0045] Such as figure 1 As shown, the present invention provides a light distribution method of a power type LED integrated module. The LED integrated module used in the light distribution method includes a conjoined lens seat, a lens body, and an LED light source corresponding to the lens body. The lens body is an asymmetric curvature structure; the light distribution method adopts the method of area division to realize the purpose of uniform illumination of the target surface, and the illumination area projected onto the road surface can be elongated, and the energy of the outgoing light projected into the two areas is Asymmetric distribution, that is, the light projected to the sidewalk area is weak, and the light projected to the motorway area is strong; the specific steps are as follows:

Abstract

The invention relates to a light distribution method for a power type LED integrated module. A region segmentation method is adopted for achieving the purpose of even illumination of a target face, an illumination region projected to the road surface is lengthened, energy, projected to two regions, of emitted light is in asymmetrical distribution, in other words, the light projected to the sidewalk region is weak, and the light projected to the motor vehicle region is high. The light distribution method includes the steps that firstly, the emitted light of a light source is partitioned into a certain number of partition regions according to the angle, and a target face is correspondingly divided into multiple regions; secondly, the relation between the projection luminous flux in the adjacent angle ranges and the received light of the target illumination region is established; and thirdly, relative distribution of a light distribution curve at all angles is calculated according to the corresponding relation and the projection angle of the LED light source, finally, an integrated module lens curved surface is constructed according to the curve rate of the light distribution curve, and the space coordinate position of the optical curved surface of the lens module is solved. According to the light distribution method, uniformity of secondary light distribution of the LED integrated module is achieved, and therefore illumination and brightness distribution of the illumination region is uniform.

Description

technical field [0001] The invention relates to the field of LED lighting, and specifically designs a light distribution method of a power type LED integrated module. Background technique [0002] The power LED lighting system product is a new type of solid-state cold light source based on the principle of semiconductor light emission. Judging from the current development trend, the power-type high-brightness white light-emitting diode (LED) will become a mercury-free, energy-saving green light source. Compared with other light sources, semiconductor lighting has the advantages of energy saving, high efficiency, long life, mercury-free and environmental protection, which can save a lot of energy consumption, reduce greenhouse gas emissions, and reduce environmental pollution. It can be expected that semiconductor lighting materials and devices will become a new generation of green lighting sources by virtue of their unique advantages such as high efficiency, energy saving, ...
