Detailed Description

Example (b):

the scheme provides a new decorative lighting device to make up for the market vacancy in the field of lighting decoration at present. As shown in fig. 1 to 7, a lamp includes a light source 111 emitting light at a full angle, the light source 111 includes a light emitting region 111a emitting a first light 121, and a light path adjusting device 101, the inner wall of the light path adjusting device 101 is provided with a plurality of reflective surfaces 102, a gap is provided between any two adjacent reflective surfaces 102, an included angle is present, 0 ° < epsilon < 180 °, the plurality of reflective surfaces 102 are disposed around the light emitting region 111a and reflect a portion of the first light 121, one surface of the plurality of reflective surfaces 102 reflecting a portion of the first light 121 is a concave surface, one end of the light path adjusting device 101 close to the light emitting region 111a is a light receiving end 101a, one end of the light path adjusting device 101 far away from the light emitting region 111a is a light emitting end 101b, the light receiving end 101a receives the first light 121, the plurality of reflective surfaces 102 extend from the light receiving end 101a to the light emitting end 101b along an emitting direction of the first light 121, and the first light 121 not reflected by the plurality of the reflective surfaces 102 and the first light 121 reflected by the And the second light 122 exits through the light exit end 101 b. In this embodiment, the inner wall of the optical path adjusting device 101 is provided with a plurality of reflecting surfaces 102, and the reflecting surfaces 102 are disposed around the light emitting region 111a of the light source 111. Since the light source 111 emits light at a full angle, the first light 121 emitted from the light emitting region 111a is emitted randomly and received by the plurality of reflective surfaces 102 disposed around the light emitting region 111 a. The first light 121 includes 121a to 121e, where 121a to 121d are portions of the first light 121 received by the

reflective surface

102, and 121e is a portion of the first light 121 that can directly exit. And a gap is arranged between any two adjacent reflecting surfaces 102, and an included angle epsilon is formed, wherein epsilon is more than 0 degrees and less than 180 degrees, so that the first light 121 is designed to be not converged into one beam of light but to be emitted by a plurality of beams of light when being received by the reflecting surfaces 102 and reflected and emitted. If any two adjacent reflecting surfaces 102 are connected without a gap therebetween, a light beam is still emitted when being received and reflected by the two reflecting surfaces 102 at the same time, and thus a gap is required between any two adjacent reflecting surfaces 102. The included angle e =0 ° or e =180 ° between any two adjacent reflective surfaces 102, which may cause the reflective surfaces 102 not to be disposed around the light emitting region 111a, which is not desirable. Therefore, only when there is a gap between any two adjacent reflecting surfaces 102 and there is an included angle e, 0 ° < e < 180 °, each reflecting surface 102 reflects the received first light 121 out, so that the second light 122 emitted from the optical path adjusting device 101 includes a plurality of light beams. One light beam can form one light spot, so that a plurality of light spots can be formed in the second light 122, and due to the gaps between the reflecting surfaces 102, gaps also exist among the plurality of light spots formed by the second light 122 instead of the plurality of light spots being connected to form one light spot, so that the light path adjusting device 101 has a light splitting function. In this embodiment, the surface of the plurality of reflective surfaces 102 that reflects the first light 121 is a concave surface, and the radian of the concave surface can determine the emergent angle of the first light 121 reflected by the reflective surfaces 102 after emergence, so the radian of the reflective surfaces 102 can be designed, and the light-emitting angle of the second light 122 can be limited. In this embodiment, in order to make the plurality of reflecting surfaces 102 easier to fix and convenient to use, the plurality of reflecting surfaces 102 are disposed on the inner wall of the optical path adjusting device 101. The light path adjusting device 101 includes a light receiving end 101a close to the light emitting region 111a, and the light receiving end 101a is used for receiving the first light 121 emitted by the light emitting region 111 a; the light path adjusting device 101 further includes a light emitting end 101b far away from the light emitting region 111a, and the light emitting end 101b is used for ensuring that the first light 121 can be emitted to form the second light 122 after entering the light path adjusting device 101. The first light 121 emitted by the light emitting region 111a is emitted at a full angle, which allows the first light 121 to be distributed in any angle range, and it is desirable that each of the reflecting surfaces 102 can receive the first light 121 as much as possible, so that the reflecting surfaces 102 need to extend from the light receiving end 101a to the light emitting end 101b along the emitting direction of the first light 121.

In this embodiment, to meet the requirement of the customer, the reflecting surface 102 is preferably a paraboloid. As can be seen from optical knowledge, when the reflective surface 102 is a paraboloid, the reflective surface 102 reflects the received light as a collimated light. The light beams of the second light 122 are collimated, so that the light spots formed by the second light 122 are spread in a small range. Of course, the reflecting surface 102 is not limited to a paraboloid, and can be designed to be an ellipsoid or a sphere according to actual needs.

Although the optical path adjusting device 101 can divide a light beam into a plurality of light beams, in order to increase the number of light beams emitted from the optical path adjusting device, it is necessary to increase the number of reflecting surfaces 102 on the inner wall of the optical path adjusting device 101. The volume of the optical path adjusting device 101 is limited, and to increase the number of the reflecting surfaces 102 on the inner wall of the optical path adjusting device 101, the volume of a single reflecting surface 102 needs to be reduced, which also increases the difficulty in manufacturing the optical path adjusting device 101. Therefore, it is preferable that the optical splitter 103 further includes a first reflecting surface 103a, the first reflecting surface 103a is a concave surface, the first reflecting surface 103a receives the second light 122 and reflects and emits the third light 123, and a plurality of sub-planes are arranged on the first reflecting surface 103 a. In this embodiment, the optical splitter 103 includes a first reflective surface 103a, and a plurality of sub-planes are arranged on the first reflective surface 103a, and each sub-plane can reflect and emit the received light, so that one light beam is divided into a plurality of light beams, thereby implementing the light splitting function. And because the first reflecting surface 103a is a concave surface, several sub-planes are arranged on the concave surface, so that there is a certain angle difference between any two adjacent sub-planes. The existence of the angle difference enables a certain space to exist among a plurality of light spots formed by a plurality of beams of light emitted from the first reflecting surface 103a instead of being connected together to form an integral light spot, and the distribution of the plurality of light spots can generate a starry sky visual effect, so that the device is suitable for the field of illumination decoration. The second light 122 emitted from the optical path adjusting device 101 itself comprises a plurality of light beams, and the light beams form third light 123 comprising more light beams after being reflected by a plurality of sub-planes on the first reflecting surface 103a, so that the light emitted from the whole device forms more light spots.

In order to make the beam splitter 103 receive the second light 122 from the optical path adjusting device 101 as much as possible, the light emitting angle of the second light is preferably γ, and γ =60 °. If the light emitting angle of the second light 122 is too large, the first reflecting surface 103a on the light beam splitter 103 needs to receive more second light 122, and the distance between the first reflecting surface 103a and the light emitting end 101b of the light path adjusting device 101 needs to be close enough. However, if the distance between the first reflecting surface 103a and the light emitting end 101b is too short, the third light 123 emitted from the first reflecting surface 103a may be blocked by the optical path adjusting device 101. If the emitting angle of the second light 122 is too large, but the distance between the light emitting end 101b and the first reflecting surface 103a is not desired to be too close, the area of the first reflecting surface 103a can be increased, which increases the volume of the whole device. However, if the light emitting angle of the second light 122 is too small, the spreading area of the second light 122 on the first reflecting surface 103a is too small, so that the area of the first reflecting surface 103a receiving the second light 122 is too small, and the number of light spots formed by the emitted third light 123 is not as designed. After many deductions, it is found that the second light 122 can be better received by the first reflecting surface 103a only when the light emitting angle γ of the second light 122 is 60 °. After determining the emitting angle of the second light 122, we also need to determine the distance from the light end 101b to the first reflecting surface 103 a. Here, for the convenience of defining the distance between the light emitting region 111a and the first reflecting surface 103a, it is preferable that the first reflecting surface 103a is a circular arc surface, the first reflecting surface 103a includes a central point p, an optical axis of the second light 122 passes through the point p, the light emitting region 111a includes a light emitting point o, a chord length of the circular arc surface is D,

. The light emitting region 111a is disposed opposite to the first reflective surface 103 a. The first light 121 emitted from the light emitting region 111a is divided into a large-angle light which is received by the light path adjusting device 101 and reflected to exit, and a small-angle light which directly exits through the light path adjusting device 101. And reflecting the outgoing large-angle light and directly emittingThe small angle light forms the outgoing second light 122, when the optical axis of the first light 121 and the optical axis of the second light 122 coincide. The first reflecting surface 103a is preferably a circular arc surface, such that the first reflecting surface 103a includes a center point p, and thus the optical axis of the second light 122 passing through the point p is equivalent to the optical axis of the first light 121 passing through the point p. The light emitting region 111a includes a light emitting point o, and since the area of the light emitting region 111a is extremely small, the light emitting region 111a can be approximated to the light emitting point o. The connection point o is connected to the point p, and the length of the op in this case can be understood as the distance from the light emitting region 111a to the first reflective surface 103 a. Also, since the light emitting angle γ of the second light 122 is 60 °, it can be derived

I.e. only have

The first reflecting surface 103a can receive the second light 122 to the maximum extent. However, since the position of the light emitting region 111a and the light emitting area vary due to the light path adjusting device 101, that is, the light emitting end 101b of the light path adjusting device 101 is equal to the light emitting region 111a, it is necessary to determine the optimal distance between the first reflecting surface 103a and the light emitting end 101 b. The distance between the light receiving end 101a and the light emitting end 101b of the optical path adjusting device 101 is L, and the optimal distance between the first reflecting surface 103a and the light emitting end 101b is L

L。

Although the optimal distance from the light emitting end 101b to the first reflecting surface 103a is found, the light emitting region 111a is disposed opposite to the first reflecting surface 103a, so that the third light 123 emitted from the first reflecting surface 103a is reflected and emitted toward the light emitting region, which still causes the light path adjusting device 101 to block the third light 123. Therefore, preferably, the first reflecting surface 103a can be rotated by using the center point p of the first reflecting surface 103a as a rotation point. In order to prevent the first reflecting surface 103a from deflecting too much, resulting in the first reflecting surface 103a not receiving the second light 122, it is preferred that the angle between the optical axis of the second light 122 and the optical axis of the third light 123 is β, 30 ° < β < 75 °. In this case, no matter how the first reflecting surface 103a deflects, the third light 123 emitted from the first reflecting surface 103a is desirable as long as an angle between the optical axis of the second light 122 and the optical axis of the third light 123 is ensured to be 30 ° < β < 75 °. In order to reduce the blocked third light 123, we can also start with the first reflective surface 103a, and preferably, the first reflective surface 103a is a spherical surface. From optical knowledge, the inner wall of the sphere can reflect light towards the center of the sphere. Therefore, when the first reflecting surface 103a is a spherical surface, the third light 123 emitted from the first reflecting surface 103a is focused toward the center of the sphere, so that the spreading range of the third light 123 is small, and the possibility of the third light 123 being blocked is reduced.

In this embodiment, the device further includes a first reflecting mirror 104, and the first reflecting mirror 104 is located on the optical path of the third light 123 and reflects and emits the received third light 123. The first reflecting mirror 104 is disposed on the optical path of the third light 123, so that the emitting direction of the third light 123 can be adjusted by adjusting the angle of the first reflecting mirror 104, facilitating the emission of the third light 123.

In this embodiment, the sub-planes on the first reflecting surface 103a are plane mirrors, and the plane mirrors are uniformly arranged. The plane mirror is easy to obtain, cheap, and very suitable for being used as a sub-plane on the first reflecting surface 103a, and the plurality of plane mirrors are uniformly arranged so that the space on the first reflecting surface 103a can be fully utilized.

In this embodiment, in view of the problem of production cost, it is preferable that the reflecting surface 102 is a concave reflecting mirror. The reflector is a device commonly used in the field of illumination, and is mature in processing technology, and the processing cost of the concave reflector is also low, so that the concave reflector is very suitable for our needs.

In summary, the inner wall of the optical path adjusting device 101 is provided with the plurality of reflecting surfaces 102, and a gap is formed between any two adjacent reflecting surfaces 102 and an included angle epsilon is formed, where epsilon is greater than 0 degrees and less than 180 degrees, so that the reflecting surfaces 102 are designed to be independent from each other, so that the first light 121 is received by the plurality of reflecting surfaces 102 and reflected and emitted, and then does not converge to form a beam of light, but multiple beams of light are emitted simultaneously, and further the second light 122 forms a plurality of independent light spots. In order to increase the number of light spots formed by emergent light, a light beam splitter is introduced. A plurality of sub-planes are uniformly arranged on the first reflecting surface 103a of the optical beam splitter 103, and each sub-plane reflects the received second light 122 to emit, that is, the number of light beams included in the third light 123 formed by the plurality of light beams included in the second light 122 after being reflected by the first reflecting surface 103a is further increased, and further, the number of light spots is further increased.

The above description of several embodiments of the present invention has been provided for the purpose of illustration, but the present invention is only a preferred embodiment of the present invention, and should not be construed as being limited to the scope of the present invention. All the equivalent changes and improvements made according to the application scope of the present invention should fall within the patent coverage of the present invention.
