"An LED without a lens is like a camera without lens—full of potential but uncontrolled."

    In this article, we will delve into what LED len is and the knowledge of custom LED lenses.

• Basic knowledge about LED lenses

1.What is led lens?

    An LED lens is an optical element specifically designed to control and optimize the light emitted by an LED light source.

    It is typically mounted on an LED chip and is widely used in lighting, automotive, and electronic equipment industries.

2.Are led light good or better for your eyes?

    Sometimes we are asked whether LED lights are harmful to our eyes. Actually, under normal circumstances, except for some cheap products with severe flicker, LED lights that meet safety standards are generally harmless to the eyes.

    And how can you tell if a light is flickering? You can open your phone's camera and point it at the LED light. If you see wavy flickering, it means the light is flickering.

    Additionally, warm light is gentler on our eyes than cool white light.

    Qualified LED lights have low blue light, no flicker, and uniform and stable light. Incandescent bulbs have low-frequency flicker and uneven brightness, while some energy-saving bulbs have blue light hazards and flicker problems; all are less eye-friendly than LED lights.

3.What’s the difference between led light lens and led magnifying lens?

(1)Different Optical Design Principles

    Camera lenses aim for precise imaging, while telescopes, microscopes, and magnifying glasses aim to magnify objects and restore their true details.

    LED lenses, however, primarily control the distribution of light. They are designed with focusing and diffused structures to control the direction of light and improve luminous efficiency, depending on the application.

    Just as we look at resolution parameters and lens sharpness when buying a camera, we primarily look at the beam pattern of an LED lens to see if it meets the lighting needs of different scenarios.

(2)Different Materials and Manufacturing Methods

    Traditional lenses are primarily made of optical glass, produced through grinding and polishing. While achieving extremely high light transmittance and zero image distortion, they are heavy and brittle.

    LED lenses, on the other hand, are mainly made of PC and PMMA. Although their light transmittance is not as high as traditional lenses, they are lighter and more impact-resistant. And LED lenses are injection molded, making them heat-resistant and UV-resistant.

(3)Production Speed and Cost of Customized Production

    Because glass grinding has a long cycle, the production cycle for customized traditional lenses can reach several months.

    LED lenses, through mold making and rapid injection molding, have a shorter production cycle and relatively lower costs for mass production.

    In summary, traditional lenses aim to better "reproduce the world," while LED lenses aim to better control light to "illuminate the world."

4.What are the different materials used for LED light lenses?

Acrylic (PMMA): High light transmittance, but not heat resistant, easily cracked when dropped. Commonly used in outdoor billboards, landscape lighting, and home decoration.

Plastic (PC): Lightweight, impact resistant, heat resistant, low cost, easy to injection mold, suitable for mass production and customization, but relatively low light transmittance. Commonly used in outdoor streetlights, car headlights, stage lighting, helmets, etc.

Optical glass: Highest light transmittance, heat resistant, but heavy and fragile, long lead time, extremely high mass production cost. Commonly used in scientific instruments, high-end projectors, etc.

Silicone: Highly flexible, easily bent, impact resistant, but poor light transmittance. Suitable for wearable devices, medical devices, etc.

5.What are the core functions of LED light lens?

(1) Light Control: By altering the direction of light through optical design (such as lens curvature), it achieves focused or diffused light effects. This meets the long-range lighting needs of applications like car headlights and flashlights, and is also suitable for indoor lighting, outdoor streetlights, billboards, and other large-area lighting scenarios.

(2) Improved Luminous Efficiency: Reduces light loss and improves the lighting efficiency of LED lights.

(3) Improved Uniformity: Eliminates hot spots and dark areas, ensuring consistent light distribution across the illuminated area.

(4) Protective Function: Physically isolates LEDs from dust and moisture, extending their lifespan.

• Custom LED Lens

1.Why do we need custom LED lenses?

(1) Precise light distribution, resolving issues of uneven light spots and dark areas at the edges;

(2) Spatial adaptation, preventing light leakage due to incompatibility with luminaires;

(3) Cost optimization, avoiding material waste caused by over-design;

(4) Adaptability to special environments, extending the lifespan of luminaires under extreme conditions.

    In summary, based on different application scenarios and needs, we can provide you with customized optical designs, rapid prototyping, and delivery of customized, high-efficiency, reliable, and low-cost lens led, guaranteed to satisfy you!

2. The complete process of customizing LED light lenses

(1) Understand Needs: We fully consult with clients to understand the application scenarios of the LED lights and the requirements for matching lenses (optical angle, size, materials, etc.), including the lighting target, space constraints, etc. If the client has design drawings, it will be even more convenient.

(2) Optical Design: Our designers with fifteen years of experience in the LED industry will respond quickly, translating your needs into optical parameters using simulation software. Our design process at Sunshineopto takes only about one week.

(3) Mold Making and Quality Inspection: After drawing approval, make trial tooling mold to get out the samples to test and simulate the light distribution for final approval. The fast finishing time is 25 days.

(4) Sample Confirmation: We will send a small number of samples to the client to confirm that mass production is possible.

(5) Mass Production, Logistics, and After-Sales Guarantee: After the mold is polished and the final mold is made, mass production is carried out using injection molding machines (there are 30 machines ranging from 60 tons to 320 tons). At Sunshineopto, we will produce the final mold within 25 days and guarantee rapid delivery using maximum production capacity. After production is complete, we will also inspect each lens to ensure it is clean, intact, and free of cracks.
