Secondary optical design and light distribution application

With the progress of society and the improvement of consumption level, today's commercial activities are not just shopping. For example, when you want to buy a dress, you start to ask for affordable prices, Sincere service... And most importantly, a comfortable experience, And a comfortable experience is inseparable from a good lighting experience. Different commercial spaces give people different feelings.

Most of these lighting effects come from the function of secondary optical lens. Today we will explain the solutions of LED secondary optical design and light distribution application, so that you can have a deeper understanding of the role of secondary optical lens.

LED lens is an optical system closely connected with LED, which can enhance the use efficiency and luminous efficiency of light. Different lenses can be used to change the light field distribution of LED according to different effects. Other types of lenses, such as those for cameras, telescopes, etc., do not belong to the scope of this paper. This paper focuses on the secondary condensing lens for high-power LED.

Secondary optical design

Optical lens material

The materials used for optical lens are generally PC, PMMA, glass, silica gel, etc.

Glass material: high light transmittance and good temperature resistance, but the manufacturing process is complex and the cost performance is low.

The materials used for optical lenses are generally optical grade PC transparent materials or optical grade PMMA transparent materials, which are applied in different fields according to the characteristics of these two materials.

The two main design problems to be solved in secondary optical design are "light collection" and "lighting".

Application of optical lens in real life

Commercial lighting

From the perspective of daily consumption forms and contents, commercial lighting can be divided into four categories: shoes, clothing, luggage monopoly (automobile exhibition hall) lighting, catering chain lighting, shopping malls and supermarkets lighting, furniture and building materials store lighting, etc.

Different commercial spaces have different needs, and lighting applications are also different. But most commercial lighting is inseparable from cob lens.

Commercial lighting application

Stage illumination

With the development of the plot, stage lighting equipment (such as lighting lamps, slides, control systems, etc.) and technical means are used to display the environment, render the atmosphere, highlight the central characters with light color and its changes, create a sense of stage space and time, shape the external image of stage performance, and provide necessary lighting effects (such as wind, rain, cloud, water and lightning).

Stage illumination application

Outdoor lighting

Outdoor lighting refers to lighting other than indoor lighting. Outdoor lighting is required to meet the needs of outdoor visual work and achieve decorative effects. Compared with home lighting, outdoor lighting has the characteristics of high power, strong brightness, large volume, long service life and low maintenance cost.

Outdoor lighting lamps mainly include: lawn lamp, courtyard lamp, tunnel lamp, floodlight, underwater lamp, street lamp, wall washing lamp, landscape lamp, buried lamp, etc.

Outdoor lighting application

Street lamp / industrial and mining lamp

Street lamps refer to lamps that provide lighting functions for roads, and generally refer to lamps within the range of pavement lighting in traffic lighting. Street lamps are mainly used in urban streets, park roads, courtyards, basketball courts and other places that need lighting.

Industrial and mining lamps refer to the general name of lamps used in the production and operation areas of factories, mines, warehouses and high sheds. In addition to various lamps used in normal environments, there are also explosion-proof lamps and anti-corrosion lamps used in special environments.

Summary

The lens is mainly used to guide the light reasonably according to different application scenarios of lamps, so as to meet the requirements of light output effect in the service environment. Every aspect of life has the shadow of a lens. In the future, the lighting application of lens is still evolving... Now, do you know how lens works in life?
