Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0020] The method of the present invention is mainly to place adjacent staggered common LEDs between the polarized transmissive part and the light-rotating reflective part, so that each common LED is located at the edge of the polarized transmissive part where the folded polarized beam splitting film array protrudes toward the common LED. Below the side, the natural light emitted by ordinary LEDs is concentrated first, and then becomes polarized light vibrating in a specified direction after the joint action of the polarization transmission component and the optical rotation reflection component, and is output from the polarization transmission component.

[0021] From figure 1 and figure 2 It can be seen that the polarized light headlight for motor vehicle anti-glare lighting made according to the above method mainly includes a concentrati...

Abstract

The invention discloses a method for making a polarized light illuminating lamp by using ordinary LEDs. Adjacent and staggered ordinary LEDs are placed between the folded polarized beam splitting film array and the optical rotation reflecting part, and all are located in the folded polarized beam splitting film array. Convex to the bottom of the edge of the ordinary LED side, so that the polarized light emitted by the ordinary LED and perpendicular to the specified vibration transmission direction is reflected back to the direction of the light source through the folded polarization beam-splitting film array, and rotated to the folded polarization beam-splitting film array through the optical rotation reflector. The vibration transmission direction is reflected back, so that almost all the natural light emitted by ordinary LEDs is converted into linearly polarized light output vibrating in the same direction. The method proposed by the present invention does not obtain polarized light by removing the light of a certain vibration direction in the natural light emitted by ordinary LEDs, which will lose half of the light intensity, but converts all the light emitted by ordinary LEDs to the same vibration direction. achieve its polarized output.

Description

technical field [0001] The invention relates to a technology and device for motor vehicle lighting, in particular to a method and application for making a polarized lighting lamp by using ordinary LEDs. Background technique [0002] LED has been applied in many fields due to its low voltage, high efficiency, long life, strong applicability, good stability, short response time, no pollution to the environment, rich colors, etc., and with the development of high-brightness LED With success, LEDs are no longer just used as indicator lights, and their applications in the field of lighting have gradually increased. Now they can be used as lighting lamps in the headlights of motor vehicles. However, the current LED lamps emit all natural light, which is powerless in some occasions that require polarized lighting (such as polarized headlights used for anti-glare lighting of motor vehicles). Contents of the invention [0003] The purpose of the present invention is to solve th...
