81, the Y axis defines the length direction of the

81, and the X axis defines the width direction of the lens 81 (the X axis is the direction toward the paper).

The upper

8111 and a rear upper

8112 by using a W axis as a reference line as shown in fig. 14A, wherein the W axis is located in a negative direction of a middle Y axis of the XYZ coordinate axes and passes through an intersection point of the lower

812 and the

816, the W axis is further a normal of the upper

811, and a boundary between the front upper

8111 and the rear upper

8112 is smooth.

In this embodiment, the front upper

83 uniformly spread and exit the

81. The rear upper

8112 is a light receiving surface, and the rear upper

812 along a middle point of the Y axis direction, the V axis is further a normal of the lower

812, and a junction between the front lower

8121 and the rear lower

8122 is smooth.

The lower

812 is asymmetrical back and forth (asymmetrical in the Y-axis direction), and thus the curved surface equations of the front lower

812 in the X-axis direction₂Value f₃The values are respectively positively correlated with the curvature changes of the front lower

8121 and the rear lower

8122 along the Y-axis direction, in the embodiment, f₁Value f₂Value andf₃the values are taken as: 0.1, 0.037037 and 0.05.

The upper

811 and the lower

83 passes through the lower

812, the light continues to be totally reflected by the

83 through the upper

811.

Referring to fig. 16A-16B, in the present invention, the

81 and the

82 together form an optical system. The light emitted by the

83 accommodated in the

821, the

822 or the third reflector 823), and then projected at a certain angle, so as to achieve the best light-emitting efficiency. In this embodiment, the light extraction efficiency can reach more than 70%.

The specific light path of the

10 can be divided into the following:

light path 1: on the basis of the above optical paths i-v, the light refracted by the

81 is reflected by the first reflecting cover 821 (as shown in fig. 16B), so as to implement the polarized light irradiation at a certain angle. The height of the light irradiation of the

10 can be adjusted by adjusting the angle between the first reflecting

821 and the

822 and/or the third reflector 823 (as shown in fig. 16A), so that light polarized light irradiation is performed at a certain angle, and the projection area range and the illumination intensity of the

10 can be adjusted by adjusting the included angle between the

822 and/or the

823 and the

81.

In this embodiment, the three

83 are coplanar, and the light beams with increased angles emitted by the adjacent

83 are reflected by the

822 or the

823 and uniformly emitted out of the

10, so that the light beams can be uniformly distributed on the irradiated object by using the optical system, and occurrence of local light spots is avoided.

81 may be reflected by one or more of the

821 and the

822, 10, so that light rays with different angles can be projected. The specific optical path is determined by the angle of the light, and therefore, the optical path is not limited.

81, the optical system has an effect of condensing light of the LED or the like in cooperation with the

83, wherein the whiter the color is, the larger the illuminance value is.

82, and then be projected toward a certain angle. In addition, the height, range, illuminance, etc. projected by the LED projector can be further adjusted by adjusting the included angle (e.g., 70 ° -100 °) between the

81 and the

82, for example, the light projection angle of the LED projector can be raised by adjusting the included angle (e.g., 70 ° -100 °) between the

821 and the
