The current curing light generally comprises a reflecting shade and a light source arranged in the reflecting shade, wherein the reflecting shade is provided with a light outlet, light emitted by the light source is transmitted to the outside of the reflecting shade through the light outlet after being reflected for a plurality of times in the reflecting shade, and the light outlet of the reflecting shade faces to a part needing light curing, so that the curing light can be utilized for light curing. However, when light emitted by the light source propagates to the inner surface of the reflector, the incident angle is smaller, the folding degree of the light path is higher, so that the number of times of light emitted by the light source is more in the reflector, more light energy loss can occur in the process of multiple reflections, the light intensity is reduced, the light intensity at the light outlet is insufficient, and the curing efficiency is lower.

Based on the above, the related art adopts a mode of increasing the included angle between the reflecting surface of the reflecting shade and the light emitting surface of the light source, so as to reduce the folding degree of the light path in the reflecting shade. Specifically, the reflector has a bottom surface and a side surface surrounding the bottom surface, the light source is arranged on the bottom surface and is positioned in the reflector, the reflector is in a horn shape by increasing the included angle between the side surface and the bottom surface, and the included angle between the reflecting surface of the reflector and the light emitting surface of the light source can be increased, so that the incident angle when light emitted by the light source propagates to the reflecting surface of the reflector is increased, correspondingly, the reflecting angle of the light emitted by the light source after being reflected on the reflecting surface of the reflector is also increased, the distance propagated in the depth direction of the reflector is increased after the light is reflected once, and the light emitted by the light source can propagate to the outside of the reflector after being reflected for a small number of times. Although the number of light reflection times is reduced, the energy loss in the reflection process is reduced to a certain extent, and the dispersion degree of the emergent light at the light outlet is increased, so that the luminous flux in unit area is still lower, namely the light intensity is lower.

In the related art, the light intensity of the emergent light at the light outlet is enhanced by increasing the light emitting area of the light source, but the light intensity at the light outlet of the reflecting cover is increased by the method, the space occupied by the light source is increased, and the problem of large light energy loss caused by excessive internal reflection times of the reflecting cover is not solved, so that the effective utilization rate of the light emitted by the light source is lower.

In order to solve the above problems, the present application provides a curing lamp, through setting up the reflector panel in the reflector, wherein, the reflector panel's reflector panel is located between the light emitting surface of light source and the reflector panel's reflector panel, the contained angle between reflector panel's reflector panel and the light emitting surface of light source is the obtuse angle, the contained angle between reflector panel's reflector panel and the light emitting surface of light source is right angle or obtuse angle, and the contained angle between reflector panel's reflector panel and the light emitting surface of light source is greater than the contained angle between reflector panel's reflector panel and the light emitting surface of light source, thereby make the reflection angle on the reflector panel's the reflector panel and on the reflector panel's the reflector panel all great, and the reflector panel has stronger spotlight ability than the reflector panel, realized when reducing the reflection light energy loss, increase the degree of gathering of emergent light, make the light intensity of the light beam that finally propagates outside the reflector panel higher.

Fig. 1 shows a schematic structural diagram of a curing light in an embodiment of the present application. Fig. 2 shows a schematic diagram of the light path of the curing light in an embodiment of the present application.

Referring to fig. 1 and 2, the curing light provided in an embodiment of the present application includes a reflector 10, a light source 20 and a reflector 30, where the reflector 10 includes a mounting surface 11 and a first reflecting surface surrounding the periphery of the mounting surface 11, one end of the first reflecting surface far away from the mounting surface 11 forms a light outlet 13, the light source 20 is disposed on the mounting surface 11 and can emit light in a direction far away from the mounting surface 11, the reflector 30 includes a second reflecting surface at least partially surrounding the periphery of the light source 20, one end of the second reflecting surface is connected to the first reflecting surface, and the other end is connected to the mounting surface 11; the included angle A between the first reflecting surface and the mounting surface 11 is a right angle or an obtuse angle, the orthographic projection of the light outlet 13 on the plane of the mounting surface 11 completely covers the mounting surface 11, and the included angle B between the second reflecting surface and the mounting surface 11 is an obtuse angle, wherein B is more than A.

The curing lamp may specifically be an ultraviolet curing lamp (Ultraviolet curing, UV curing). The cross-sectional shape of the reflector 10 may be, in particular, circular, elliptical, triangular, quadrangular, or a combination thereof. The number of the reflection plates 30 may be one or more, and when the number of the reflection plates 30 is plural, the plurality of reflection plates 30 may be disposed at intervals or continuously along the circumferential direction of the inner wall of the reflection housing 10, and the plurality of reflection plates 30 may be of a split type structure or an integral type structure. The light source 20 is electrically connected with the circuit board, the light source 20 comprises one or more point light sources 20, and when the light source 20 comprises a plurality of point light sources 20, the point light sources 20 can be arranged in an array to form a larger luminous surface, and the shape of the luminous surface can be circular, elliptic, triangular, quadrilateral or a combination thereof.

According to the curing light provided by the embodiment of the application, the reflector 10 comprises the mounting surface 11 and the first reflecting surface surrounding the mounting surface 11, the included angle A between the first reflecting surface and the mounting surface 11 is a right angle or an obtuse angle, compared with the included angle between the first reflecting surface and the mounting surface 11, the included angle A is an acute angle, so that the incident angle when light emitted by the light source 20 mounted on the mounting surface 11 propagates to the first reflecting surface is larger, correspondingly, the reflecting angle of the light emitted by the light source 20 after being reflected on the first reflecting surface is larger, therefore, after being reflected once, the distance of the light propagating in the depth direction of the reflector 10 is increased, the light emitted by the light source 20 is directly propagated to the outside of the reflector 10 through the light outlet 13 with a large probability after being reflected on the first reflecting surface, namely, the reflecting times of the light emitted by the light source 20 in the reflector 10 are smaller, so that the energy loss caused by reflection is reduced, and the curing efficiency is improved. Further, the reflector 30 is disposed in the reflector 10, the reflector 30 includes a second reflecting surface at least partially surrounding the periphery of the light source 20, one end of the second reflecting surface is connected to the first reflecting surface, the other end is connected to the mounting surface 11, and an included angle B between the second reflecting surface and the mounting surface 11 is an obtuse angle, so that the number of reflection times of the light emitted by the light source 20 on the reflector 30 is less, energy loss caused by reflection is further reduced, and curing efficiency is improved. In addition, because the included angle a between the first reflecting surface and the mounting surface 11 is smaller than the included angle B between the second reflecting surface and the mounting surface 11, the light condensation effect of the first reflecting surface is better, that is, the light condensation effect of the reflecting surface near the light outlet 13 is better, so that the light intensity at the light outlet 13 is improved. Meanwhile, the orthographic projection of the light outlet 13 on the plane of the mounting surface 11 completely covers the mounting surface 11, so that the light emitting area of the light source 20 is smaller than the light emitting area of the light outlet 13, and the light emitting area of the light source 20 is reduced under the condition of ensuring that the light emitting area is larger.

In some embodiments, the angle a between the first reflective surface and the mounting surface 11 satisfies the condition: a is more than or equal to 90 degrees and less than or equal to 135 degrees; the angle B between the second reflective surface and the mounting surface 11 satisfies the condition: b is more than or equal to 120 degrees and less than or equal to 165 degrees. Based on the included angle range, the curing lamp can obtain a good curing effect, and the curing efficiency and the curing uniformity are improved. To verify the conclusion, the present inventors have tested the light energy at the light outlet 13 based on the principle of single variable, by changing the angle a between the first reflecting surface of the reflector 10 and the mounting surface 11 in the case that the angle B between the second reflecting surface of the reflector 30 and the mounting surface 11 is 135 °, and the test results are shown in the following tables 1 and 2:

TABLE 1

TABLE 2

From the test data in tables 1 and 2, it can be seen that when the included angle a between the first reflecting surface and the mounting surface 11 increases from 90 ° to 135 ° in sequence, the light energy at the light outlet 13 increases in sequence and then decreases in sequence, wherein when the included angle a is 102 °, the light energy is maximum.

Further, the first reflecting surface and the second reflecting surface can be plated with reflecting materials so as to improve the reflecting effect.

In some embodiments, the orthographic projection of the first reflective surface on the plane where the mounting surface 11 is located is in a circular shape, that is, each area of the first reflective surface is smoothly connected, so that the folding angle and the fold can be avoided, and the reflective effect of the first reflective surface is improved.

Further, the front projection of the first reflecting surface on the plane of the mounting surface 11 is in a circular ring shape, the front projection of the second reflecting surface on the plane of the mounting surface 11 is in a circular ring shape, and the outer edge of the front projection of the second reflecting surface on the plane of the mounting surface 11 covers the inner edge of the front projection of the first reflecting surface on the plane of the mounting surface 11. Thereby enhancing the overall light reflecting effect within the reflector 10. Specifically, the reflector 10 and the reflector 30 may be formed of two flared truncated ends having different tapers.

In some embodiments, the mounting surface 11 is quadrilateral; the first light reflecting surface includes four first sub-light reflecting surfaces 12 connected to four sides of the mounting surface 11, respectively, and two first sub-light reflecting surfaces 12 connected to adjacent two sides of the mounting surface 11 are connected to each other. Wherein the first sub-reflecting surface 12 may be a planar surface or a curved surface. Based on this structure, the reflector 10 has a good light reflecting effect, and is simple in structure and convenient to mold.

Further, the orthographic projection of the second reflecting surface on the plane where the mounting surface 11 is located partially covers the connecting lines of two adjacent first sub-reflecting surfaces 12. It can be understood that when there are angles or folds on the surface of a certain structure, the reflective effect of each area of the surface of the structure is not uniform, but in the embodiment of the present application, the connecting lines of two adjacent first sub-reflective surfaces 12 are partially covered by the orthographic projection of the second reflective surface on the plane where the mounting surface 11 is located, so that the angles formed by connecting the two adjacent first sub-reflective surfaces 12 are blocked by the second reflective surface, thereby improving the uniformity of the reflective effect in the reflective cover 10. Compared with the traditional curing lamp, the curing lamp provided by the embodiment of the application reduces the light-emitting area of the light source 20, improves the curing efficiency, and improves the energy uniformity, so that the curing uniformity is more than or equal to 95%, and the problem of the curing uniformity of the curved surface product can be solved when the curing lamp is applied to the manufacturing process of the curved surface product.

Further, the second reflecting surface includes four second sub-reflecting surfaces 31, and orthographic projections of the four second sub-reflecting surfaces 31 on the plane where the mounting surface 11 is located cover four vertexes of the mounting surface 11 in a one-to-one correspondence manner, so as to shade vertex angles and folds around the vertex angles of the reflecting shade 10, and promote reflecting effect. The outline shape of the second sub-reflecting surface 31 may be triangle, quadrangle, circle or a combination thereof, and the second sub-reflecting surface 31 may be a plane or a curved surface.

Specifically, the light reflecting plate 30 includes two sub-light reflecting portions, and each sub-light reflecting portion is provided with two second sub-light reflecting surfaces 31; an installation part 32 is connected between the two second sub-reflecting surfaces 31 on each sub-reflecting part, and the installation part 32 is connected with the reflecting shade 10. The two second sub-reflecting surfaces 31 are connected through the mounting part 32, and the mounting part 32 is connected with the reflecting cover 10, so that the mounting steps of the reflecting plate 30 are reduced, the occupied area of the mounting structure is reduced, and the influence of the mounting structure on the reflecting effect is reduced.

In some embodiments, the mounting portion 32 is detachably connected to the reflector 10, so that the reflector 30 can be disassembled according to the requirement, so as to adjust the shape or the mounting angle of the reflector 30 according to the light-emitting requirement.

Referring to fig. 1 and 3, further, the mounting portion 32 includes a plane parallel to the mounting surface 11, and the mounting portion 32 is detachably connected to the mounting surface 11 by a fastener. Because the mounting portion 32 includes the plane parallel to the mounting surface 11, the contact area between the mounting portion 32 and the mounting surface 11 is larger, and based on this, when the mounting portion 32 is connected to the mounting surface 11 by the fastener, the mounting effect is more stable, and is not easy to loosen, thereby guaranteeing the light emitting effect. Wherein the fastener may be a bolt 40 or a screw.

In a specific embodiment, the bottom of the reflector 10 and the mounting portion 32 of the reflector 30 are provided with M3 threaded holes, and the reflector 30 is mounted in the reflector 10 by matching the bolts 40 with nuts. When the reflector 10 is made of metal, the fastener may also be a magnet. In addition, the reflector 10 may be provided with a fastening hole, and the mounting portion 32 may be provided with a fastening block adapted to the fastening hole, so that the mounting portion 32 may be detachably connected to the mounting surface 11.

In other embodiments, a bump or an ear plate may be disposed on the back of the reflector 30, and the bump or the ear plate is assembled with the reflector 10, so as to ensure the flatness of the reflective surface of the reflector 30.

The reflector 30 includes two sub-reflectors, each of which is bent to form three sections, the surfaces of the two sections at two ends form a second sub-reflector 31, one end in the middle forms a mounting portion 32 connected to the two second sub-reflectors 31, and the mounting portion 32 is connected to the bottom plate of the reflector 10 through an M3 bolt 40. The second sub-reflecting surface 31 has a triangular shape. In particular, the shape of the second sub-reflecting surface 31 may be adjusted based on a triangle, for example, a convex portion or a concave portion is formed on one or more sides of the triangle. The mounting portions 32 of the two sub-reflecting portions are respectively mounted at the middle sections of the two opposite sides of the mounting surface 11, so that the four second sub-reflecting surfaces 31 are respectively shielded at the four top corners of the reflector 10. The included angle between the second sub-reflecting surface 31 and the mounting surface 11 is 135 °, and the second reflecting surface is coated with a reflecting material.

According to the curing light provided by the embodiment, through the design of the light emitting area of the light source 20, the light emitting area of the light emitting opening 13, the inclination angle of the reflecting cover 10 and the inclination angle of the reflecting plate 30, the light rays with different angles emitted by the light source 20 can be emitted through the light emitting opening 13 through twice reflection at most, and the energy loss generated in the light ray reflection process is reduced. And, the reflecting plate 30 and the reflecting shade 10 are provided with reflecting coatings, so that the energy loss in the reflecting process is further reduced. By adjusting the inclination angle of the reflecting plate 30, the requirements of the cured product with the thickness of 0mm-100mm on the curing efficiency and the curing uniformity can be satisfied. When the included angle between the two sub-reflecting surfaces and the mounting surface 11 is 135 degrees, the curing uniformity can reach more than 98 percent.

In the practical application process of the curing lamp, the light emitted by the light source 20 is reflected by the reflector 30 or the reflector 10 and then is collected at the light outlet 13, so that the light energy is concentrated in a certain range, and when the light emitted from the light outlet 13 irradiates the surface of the curved surface product, the curing effect of each part of the curved surface product is uniform.
