Detailed Description
The above and further features and advantages of the present invention will be apparent from the following, complete description of the invention, taken in conjunction with the accompanying drawings, wherein the described embodiments are merely some, but not all embodiments of the invention.
As shown in fig. 1, a wall washer lens G includes a lens body M and a lens base S supporting the lens body M. The lens body M includes an inner surface J that receives light emitted from the light source L and an outer surface that emits light. A cavity R for accommodating the light source L is formed between the inner surface J and the lens base S. In the figure, the Y axis is an optical axis, the outer surface comprises a first curved surface A, a first plane H, a second curved surface B, a second plane K and a third curved surface C, and the first curved surface A and the second curved surface B are formed by rotating continuous curves for 180 degrees around the Y axis; the third curved surface C is formed by rotating a continuous curve around the Y axis by-180 degrees; the first plane H is arranged between the first curved surface A and the second curved surface B and is vertical to the Y axis; the second plane K is arranged between the second curved surface B and the third curved surface C and is vertical to the Y axis.
The first curved surface A is a total reflection surface and is used for totally reflecting light to the wall washing surface to avoid overlarge light intensity at a position close to the lamp. The profile of the first curved surface a may be defined by the following integral equation:
Figure BDA0001843141100000031
where ro is θ ═ θminThe value of the time lens, theta is the angle between the incident ray and the Y axis, and gamma is the angle between the emergent ray and the Y axis.
The second curved surface B is used for refracting light to a wall washing surface, so that the deflection of the light is realized, and the illumination uniformity is improved. The profile of the second curved surface B can be defined by solving the following integral equation:
Figure BDA0001843141100000032
where ro is θ ═ θminThe value of the lens, theta, isThe included angle between the emergent ray and the Y axis, gamma is the included angle between the emergent ray and the Y axis, and n is the refractive index of the lens.
The third curved surface C is a total internal reflection surface and is used for totally reflecting light to the wall washing surface, so that the light deflection is realized, the light effect is improved, and the illumination uniformity is improved. The profile of the third curved surface C is defined by solving the following integral equation:

where ro is θ ═ θminThe value of the time lens, theta is the angle between the incident ray and the Y axis, and gamma is the angle between the emergent ray and the Y axis.
As shown in fig. 2, a light emitting module having a lens G of the aforementioned type is an LED module, i.e., an LED light source L is mounted in a cavity R of a wall washer. Because the light emitting module is provided with the non-rotational symmetric pinup washing lens G, the light loss can be reduced, and the light effect is improved.

The conception of the invention is that the light near one side of the wall surface of the wall is reflected by the light to realize the uniform distribution of the target illumination of the wall surface of the wall, the second curved surface B is obtained by calculating the profile integral equation of the second curved surface B, the light near one side of the wall surface of the wall is difficult to overcome the peak value near the lamp by the reflection of the light alone due to the total reflection in the design process, and then the first curved surface A is introduced to convert the light with the total reflection into the total internal reflection, so that the uniform distribution of the target illumination of the wall surface of the wall is realized. The light far away from one side of the wall washing surface is reflected to the wall washing surface through the third curved surface C, and the target illumination of the wall washing surface is uniformly distributed. Because the design targets of the first curved surface A, the second curved surface B and the third curved surface C are all to realize the uniform distribution of the illumination in the area which accords with the design targets, the uniform distribution of the illumination of the wall washing surface is realized by the whole lens. The light loss can be reduced through the combined action of the three curved surfaces, and the light effect is improved.
