The First Application of New TIR Technology in BI LED Lens

19 Published by admin Feb 22,2023

As LED technology developing, Automotive lighting has evolved from a basic functional feature to a unique feature with high value potential. LED technology offers Automotive lighting manufacturers the opportunity to achieve differentiation through lighting design and additional functionality. Especially for exterior and interior lighting, the integration of the latest lighting technologies offers greater design flexibility, greater efficiency and smart functionality.

The original automotive lighting system technology is advancing, lighting has developed from a purely functional application with no real added value to a more intelligent application, providing personalize communication and driving assistance; the automotive aftermarket is also choosing the latest LED and Laser technology to develop new aftermarket automotive lighting products, such as LED lenses and laser lenses. Automotive lighting products will continue upgrading along with the development and emerging of new technologies, new applications. And there will be more and more options for automotive aftermarket lighting products.

In order to be chose by aftermarket refitting car owners, aftermarket automotive lighting modification products need to be good quality and bring good driving experience.

Aozoom's new Bi LED Lens Projector DLPD-07 lens is the latest product in the current Bi LED Automotive lighting refitting industry. The DLPD-07 lens use the latest TIR direct light technology to improve the lighting effect, driving safety and driving experience.


Water chestnut TIR superimposed total reflection lens

For the first time, Aozoom uses the water chestnut TIR superimposed total reflection lens on the latest DLPD-07 Bi LED Lens Projector. This technology will improve the light effect of the LED lighting as much as possible and apply the LED lighting to the actual lighting effect instead of being refracted. In this way, the lens can better restrain the light beam and improve the light efficiency up to 88-92%. So the low beam for DLPD-07 Bi LED Lens will be more uniform and brighter.

High Beam Direct Technology

DLPD-07 Bi LED Lens adopts dual direct light sources. Besides effective low beam, it also has strong high beam. As we know, good high beam is very important for high-speed driving. A bright and powerful high beam lighting system can improve the driving safety at night greatly, and make the night driving easier and more enjoyable.

DLPD-07 Bi LED Lens Projector use optical grade high-definition PMMA lens, the light transmittance of the lens reach 92%, and there is no yellow halo, shrinkage, variegated color, and steam bag. And so the DLPD-07 product have more uniform light output and better quality. As an optical product, LED projector lenses have strict requirements on light transmission, thermal stability, density, refractive index uniformity, refractive index stability, water absorption, turbidity, and maximum long-term operating temperature. The high-definition PMMA lens that DLPD-07 used has a durability of 10 to 20 years.

Pure copper substrate + high thermal conductivity copper tube heat dissipation + better LED light efficiency

The metal substrate can effectively solve the problem of heat dissipation, so that the thermal expansion and contraction of different materials on the circuit board can be alleviated, and the durability and reliability of the whole machine and electronic equipment can be improved. The DLPD-07 lens uses double copper tubes for heat dissipation, which can make the LED chips work more efficiently, delay the service life of components, and provide stable and reliable lighting in various harsh working environments.

High speed fan brings double guarantee one the lens high output

Bi LED lens uses cooling fan to actively dissipate heat. The cooling fan can withstand a maximum temperature of 120 degrees in a relatively closed headlight assemble, and its high temperature resistance reliability must be guaranteed. And the cooling fan DLPD-07 lens used have a good body structure design, motor coil temperature rise control, high temperature resistant magnets, electronic devices that meet the requirements of vehicle regulations, structural design of the shaft receiving part and selection of high temperature resistant bearings

At present, many bi LED lens on the market have obvious yellow spots or stray light due to lack of good optical design and supporting optical design. Good lighting should be like natural sunlight, clean and transparent, and should not have yellow light, Aozoom has developed the TIR lens series with its professional optical design experience and self-developed materials.

This DLPD-07 bi led series can effectively eliminate the yellow spots in the light beam and achieve uniform illumination. And the light transmittance reaches 88-92%. It is the top level in similar products in the industry.


What is "TIR"?

TIR refers to "Total Internal Reflection", that is, total internal reflection, also known as total reflection, is an optical phenomenon. When light enters from a medium with a higher refractive index to a medium with a lower refractive index, if the incident angle is greater than a certain critical angle θc (the light is far away from the normal), the refracted light will disappear, and all the incident light will be reflected and Do not enter medium with low refractive index.

In order to improve the utilization rate of LED light energy, a total internal reflection (TIR) lens with free-form surface was designed. The total internal reflection lens uses the principle of total reflection to collect and process light. According to the light energy distribution characteristics of LED, the discrete points on the contour curve of the refraction surface and reflection surface of the TIR lens are obtained by controlling the light path, and the spline curve is obtained by interpolation, and then the model of the TIR lens is obtained by rotating 360°. Use Tracepro software to trace the light rays passing through the TIR lens, optimize the lens structure according to the requirements of light energy utilization rate, and obtain the light energy utilization rate of 95.26% while maintaining the small size of the lens, and the divergence angle of the beam is controlled within ±15°.

TIR lens is made by using the principle of total reflection to collect and process light. Its design is to use penetrating spotlight in the front, and the tapered surface can collect and reflect all the side light, and the overlap of these two kinds of light can get perfect light utilization and beautiful spot effect. The efficiency of TIR lens can reach more than 90%, which has the advantages of high light energy utilization rate, less light loss, small light collecting area and good uniformity.
