Detailed Description
For the purposes, technical solutions and advantages of the present application, the technical solutions of the present application will be clearly and completely described below with reference to specific embodiments of the present application and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
As shown in fig. 1-4 (arrows in fig. 4 indicate light propagation paths), a lens 100 according to a first embodiment of the present application is used in a lighting fixture, such as a candle bulb or the like. The lens 100 includes a cylindrical or conical lens body 101, light incident portions 1 and light reflecting portions 2 respectively provided at both ends of the lens body 101, and light emitting portions 3 provided at side portions of the lens body 101.
The lens body 101 is provided with a side wall 102, and first and second ends located at both ends of the side wall 102, the first end having a first end face 103 intersecting the side wall 102, the second end having a second end face 104 intersecting the side wall 102. The sidewall 102 is rotated by a straight line or arc about the lens body axis 105.
The light incident portion 1 is provided at a first end of the lens body 101. The light incident portion 1 includes a light source accommodating groove 11 accommodating the illumination lamp light source 200. The light source receiving groove 11 includes a groove wall 13 at a side portion and an upper end face 12 toward the second end of the lens body 101. The upper end surface 12 is a rotation surface formed by rotating a line around the axis 105 of the lens body 101, and one end of the line is located on the axis 105 of the lens body 101. After the light source 200 is fixed in the light source accommodating groove 11, the axis of the light source 200 is positioned on the axis 105 of the lens body 101, so that total reflection is realized through the light reflecting part 2, and light control is facilitated. The upper end surface 12 is a convex surface (as shown in fig. 1-3) protruding toward the second end of the lens body 101, so as to deflect the light toward the center of the lens body 101.
The groove wall 13 surrounds the upper end face 12, and the groove wall 13 may be a light-transmitting groove wall 13. At this time, the light incident portion 1 further includes a reflecting surface 14 located at a side of the light source accommodating groove 11, and light is reflected to the light reflecting portion 2 by the reflecting surface 14. The reflecting surface 14 is located between the light source accommodating groove 11 and the side wall 3 of the lens body 101 (as shown in fig. 4), and has a simple structure, and is convenient for controlling light.
The light incident portion 1 extends beyond the first end face 103, and the lower end face forms a mounting face 15 protruding toward the first end. The substrate 300 of the lighting fixture is mounted on the mounting surface 15. So set up, simple structure, simple to operate.
The light reflecting portion 2 is provided at a second end of the lens body 101, and the lens body 101 has a concave portion 21 formed by extending from the second end surface 104 toward the first end surface 103, the concave portion 21 having an inverted cone shape, and the inner surface thereof is provided with a serrated surface 22. The serrated surface 22 includes a plurality of extension surfaces 21 that surround the axis 105 of the lens body 101 and intersect in sequence, each extension surface 21 extending in the direction from the first end surface 103 to the second end surface 104 of the lens body 101. The light emitted from the light source 200 is condensed by the light incidence part 1, is emitted to the light reflection part 2 after being condensed by the light incidence part 1, and is emitted to the light emission part 3 after being totally reflected by the two adjacent extension surfaces 21 after being emitted to the light reflection part 2.
As shown in fig. 5 and 6 (arrows indicate light propagation paths), the light paths passing through the two adjacent extension surfaces 23 are specifically: the light is incident from the light incident portion 1 to the point a of the first extension surface 231, totally reflected to the point b of the second extension surface 232, and totally reflected to the light emitting portion 3 through the second extension surface 232. When the light rays reach the point a of the first extending surface 231, the light rays are reflected to the point b of the second extending surface 232 according to the principle of total reflection, reflected from the point b of the second extending surface 232, and finally the emergent light rays and the incident light rays accord with the total reflection angle relation.
In general, total reflection is achieved inside the lens 100, and the incident angle between the light and the light reflecting portion 2 must be large enough, or the light will be transmitted, and this angle will vary according to the material of the lens 100. If the serrated surface 22 is not provided, the incidence angle of the light ray reaching the second end cannot reach the total reflection angle, and transmission is formed. After the serrated surface 22 is disposed, when the light reaches the point a of the first extension surface 231, the incident angle is greater than the critical angle of total reflection, and total reflection can be achieved. Therefore, by providing the serrated surface 22, light directed to the second end of the lens body 101 can be emitted with an optical effect of total reflection. Therefore, the serrated surface 22 is arranged, so that the light emitting efficiency can be improved, the cost can be reduced, and the service life can be prolonged under the condition that electroplating treatment is not required; the outer surface of the lens 100 is uniform, and the light reflecting portion 2 can form a bright sense, which represents the design sense of the product.
The shape of each extension surface 23 is identical. The two adjacent extension surfaces 23 are vertical, i.e. the angle between the two adjacent extension surfaces 23 is 90 degrees. And the intersection of two adjacent extension surfaces 23 is the generatrix of the recess 21, i.e. the two adjacent extension surfaces 23 are symmetrical about a plane extending along the axis 105 of the lens body 101. So set up, the total reflection optical effect that the light reflection portion 2 formed is the mirror surface total reflection optical effect, and the incident angle equals the exit angle promptly, is convenient for accuse light.
The light emitted from the light reflecting portion 2 is at least partially inclined toward the first end to form a lower emission so that the lens 100 can be applied to, for example, a candle bulb. In a specific arrangement of the light reflecting portion 2, the generatrix of the recess 21 is an arc. The axis of the recess 21 coincides with the axis 105 of the lens body 101. Along the direction from the first end to the second end of the lens body 101, the included angle between each extension surface 23 and the axis 105 of the lens body 101 is gradually increased, the minimum included angle between each extension surface 23 and the axis of the lens body 101 is smaller than 45 degrees, and the maximum included angle between each extension surface 23 and the axis of the lens body 101 is larger than 45 degrees. So configured, when the lens 100 is installed in a candle bulb, and the candle bulb is used in, for example, a crystal pendant lamp or a marble pendant lamp, the light emitted from the candle bulb can better illuminate the crystal pendant lamp or the marble pendant lamp.
The inclination angles of the respective portions of the serrated face 23 are set according to specific requirements. The shape of the recess 21 may be set according to the need.
The side walls 102 located between the first end face 103 to the second end face 104 are all configured as the light exit portion 3. The light emitted from the light emitting portion 3 is refracted. The lens 100 may be a plastic lens 100 to increase the texture as part of the light exit mask 400. Of course, the lens 100 may be a glass lens or the like.

The light incident portions 1 and 1' may be formed in different manners, and the shape, size, inclination, low point, etc. of the concave portions 21 and 21' may be adjusted accordingly so as to reflect light to a desired region through the concave portions 21 and 21 '.
Of course, in other embodiments, the upper end surface of the light source accommodating groove may be a convex surface protruding toward the second end surface, and a portion of the side wall of the lens body may be a reflective surface, or the like.
