Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The technical solutions disclosed in the embodiments of the present invention are described in detail below with reference to the accompanying drawings.
As shown in fig. 1-5, an embodiment of the present invention discloses a bulb 100, the bulb 100 is capable of distributing light to a light source 220, the bulb 100 has a generally arc-shaped structure, the bulb 100 has a cavity, and at least a portion of light emitted by the light source 220 propagates through the cavity. The inner surface of the bulb case 100 is provided with a plurality of refraction units 130, and light rays in the cavity of the bulb case 100 can be refracted on the surfaces of the refraction units 130 after entering the refraction units 130.
The refraction unit 130 is at least a portion of the pyramid structure including the vertex, for example, the refraction unit 130 may be at least a portion of the triangular pyramid structure extending from the vertex to the base. The surface facing away from the vertex is disposed on the inner surface of the bulb 100, and of course, the refraction unit 130 may also be at least a part of a pyramid structure, such as a rectangular pyramid or a pentagonal pyramid, including the vertex. Considering that the inner surface of the bulb 100 is generally a curved surface, correspondingly, the surface of the refraction unit 130 facing away from the vertex can also be a curved structure corresponding to the inner surface of the bulb 100, so as to ensure that the optical phenomena such as refraction can not occur any more during the light ray is transmitted between the refraction unit 130 and the inner surface of the bulb 100. More specifically, the wall of the bulb 100 and the refraction unit 130 may be integrally formed, which may further ensure that optical phenomena such as refraction do not occur substantially during the light propagation between the two.
The plurality of refraction units 130 include a first refraction unit and a second refraction unit, and the first refraction unit and the second refraction unit may contact each other or be spaced apart from each other. By designing the material of the refraction unit 130, the specific parameters of the structure of the refraction unit 130, and the like, as shown in fig. 2, it can be ensured that light in the cavity of the bulb 100 can be emitted to the first refraction unit, and refraction occurs in the first refraction unit, and the refracted light can be emitted to the inner side of the outer surface of the bulb 100, and by coating a reflective layer on the outer surface of the bulb 100 or the inner wall of the outer surface, it can be ensured that the refracted light can be totally reflected at the inner side of the outer surface of the bulb 100, and the reflected light can be emitted to the second refraction unit, and emitted from the second refraction unit, and the light can also be refracted in the process of being emitted from the second refraction unit, and emitted to the oblique lower side of the bulb 100, that is, the side where the light source 220 is located, and along with the continuous propagation of the light, the side of the light source 220, which is far away from the light emitting side, so as to prevent the side where the, the illumination effect of the light source 220 is improved.
It should be noted that, in order to prevent the light source 220 from blocking the light emitted from the second refraction unit, the light source 220 may be spaced apart from the plurality of refraction units 130 on the bulb casing 100, or the light source 220 may be a single point light source, so that the blocking effect of the light source 220 on the emitted light is reduced as much as possible by reducing the size of the light source 220.
As described above, the first refraction unit and the second refraction unit may be spaced apart from each other, or at least one other refraction unit 130 may be interposed between the first refraction unit and the second refraction unit, so that the light incident on the first refraction unit can be emitted from the second refraction unit and emitted to the side away from the light emitting side of the light source 220 by limiting actual factors such as refractive indexes and distances of the first refraction unit and the second refraction unit.
Optionally, in the plurality of refraction units 130, a side surface of any one refraction unit 130 is connected to a side surface of another refraction unit 130. Under this condition, the size can set up the refraction unit 130 of the greater quantity for the internal surface of the definite value's cell-shell 100 to guarantee that cell-shell 100 can provide the grading effect for the light of the greater quantity, and make the light of the greater quantity can shine to the one side of deviating from the light-emitting side of light source 220, further promote the luminance of the one side of deviating from the light-emitting side of light source 220, and promote the whole illuminating effect of light source 220. Based on the above embodiments, optionally, as shown in fig. 1 and fig. 2, the side surface of the first refraction unit is connected to the side surface of the second refraction unit, in this case, the path of the light propagating between the refraction units 130 can be reduced, so as to prevent the brightness of the light from being reduced more, and further improve the illumination effect of the light source 220.
Specifically, the shapes and sizes of the plurality of refraction units 130 may be the same, wherein the shape of the refraction unit 130 refers to the overall structure of the pyramid structure to which the refraction unit 130 belongs, that is, the shape of the bottom surface of different refraction units 130 may be different due to the different shapes (or radians) of the inner surface of the bulb 100. In the case that the plurality of refraction units 130 have the same shape, a side surface of one refraction unit 130 may be connected to a corresponding side surface of another refraction unit 130, for example, the refraction unit 130 may be at least a part of a rectangular pyramid including a vertex, four refraction units 130 may be disposed around one refraction unit 130, and the four refraction units 130 located at the periphery may be respectively connected to the four side surfaces of the one refraction unit 130 located at the center through one side surface. Of course, in case the refraction units 130 are at least part of other pyramid-like structures, the case where different refraction units 130 are flanked is similar to the previous example.
Alternatively, the shapes of the plurality of refraction units 130 may be different, for example, the first refraction unit may be at least a portion of a triangular pyramid including an apex, and the second refraction unit may be at least a portion of a rectangular pyramid including an apex. In the case that the shapes of the plurality of refraction units 130 are different, the side surfaces of two adjacent refraction units 130 may be connected to each other, and the number of refraction units 130 that can be formed on the inner surface of the bulb 100 may be made as large as possible in such a manner that the shapes of the plurality of refraction units 130 surrounding the same refraction unit 130 are the same, so as to enhance the improvement effect of the bulb 100 on the illumination effect of the side away from the light exit side of the light source 220. For example, a plurality of second refraction units having the same shape may be surrounded around the first refraction unit.
Alternatively, as shown in FIG. 1, a pattern of the refraction element 130 taken through the vertex and the plane perpendicular to the bottom surface of the refraction element 130 and centered on the bottom surface is a first pattern, and an angle of the first pattern with respect to the bottom surface is a, and 90 DEG.ltoreq.a.ltoreq.135 deg. For example, if the refraction unit 130 is at least a part of a structure including a vertex in a quadrangular prism, the angle a may be an angle between two opposite sides of the refraction unit 130. When the technical scheme is adopted, after the light is incident to the refraction unit 130, the light can be emitted from the other refraction unit 130, and under the condition that the light is emitted to the side deviating from the light emitting side of the light source 220, more light emitted from the bulb shell 100 can be transmitted close to the bulb shell 100, so that the areas of dark areas in the light source 220 and the bulb shell 100 are further reduced.
More specifically, the angles a of the plurality of refraction units 130 may be equal, and preferably, as shown in fig. 1, the angles a of the plurality of refraction units 130 may be unequal, and further, the angle a of the refraction unit 130 located in the central region of the bulb 100 may be relatively large, and since the light emitted from the light source 220 is already deflected when it is emitted to the refraction unit 130 located in the edge region of the bulb 100, and thus extends from the central region to the edge region of the bulb 100, the angles of the refraction units 130 may be gradually decreased, so that the light refracted from any one of the refraction units 130 can be emitted to another refraction unit 130 after being reflected by the inner side of the outer surface of the bulb 100, and finally emitted to the side facing away from the light emitting side of the light source 220. Of course, after the light is incident to the refraction unit 130 located at the edge of the bulb 100 and reflected by the inner side of the outer surface of the bulb 100, there may be a case where the light cannot be incident to another refraction unit 130, which is a normal phenomenon and does not depart from the above-mentioned embodiment of the present invention.
As described above, the bulb 100 has a generally arc-shaped structure, and alternatively, as shown in fig. 1, the bulb 100 includes a globe top 110, an outer surface of the globe top 110 has a spherical structure, and the refraction unit 130 is coupled to an inner surface of the globe top 110. Under the condition of adopting the structure, because the structure of the bulb shell 100 is more regular, the refraction condition of the light rays at each refraction unit 130 is easier to determine, so that the design difficulty and the processing difficulty of each refraction unit 130 are relatively lower, and further the whole processing difficulty of the bulb shell 100 is lower. In addition, under the condition of adopting above-mentioned structure, more easily through adjusting each refraction unit 130's specific parameter for refract through different refraction units 130, and the homogeneity of the light of just being emergent from cell-shell 100 is higher, and this is favorable to further promoting the illuminating effect of lamps and lanterns.
Specifically, the outer surface of the bulb 100 may have a hemispherical structure, or the outer surface of the bulb 100 may have less than a hemispherical structure. The thickness of the wall of the bulb case 100 may be determined according to the actual conditions of the material of the bulb case 100, and optionally, the thickness of the wall of the bulb case 100 is smaller than the height of the refraction unit 130, and of course, the height of the refraction unit 130 may also be made smaller than the thickness of the wall of the bulb case 100 at the position of the edge of the globe top 110 of the bulb case 100, so as to facilitate the demolding operation, and at the same time, as shown in fig. 1 and 2, each refraction unit 130 may also be made to extend in the axial direction of the side portion 120 in the direction away from the inner surface of the bulb case 100, so that the existence of the refraction unit 130 is further prevented from restricting the demolding operation during the demolding operation.
Further, as shown in fig. 1, the bulb 100 may further include a side portion 120, the globe top 110 being connected to one end of the side portion 120, and the side portion 120 being a cylindrical structural member. In the case where the side portion 120 is provided, even if the light source 220 is provided at a distance from the dome top portion 110, a certain protection effect can be provided for the light source 220 by the side portion 120; moreover, when the side portion 120 is provided, the light source 220 is disposed inside the side portion 120, so that a part of the light emitted by the light source 220 can be emitted out of the bulb 100 through the side portion 120, which makes the lighting effect of the light emitting side of the light source 220 relatively high, and further improves the diffusion capability of the bulb 100 to the lighting range of the light source 220.
Specifically, the side portion 120 and the globe top 110 may be formed in an integrated manner, both of which may be made of a light-transmitting material such as plastic or glass, and a reflective material may be coated on an outer surface of the globe top 110 to ensure that light can be totally reflected at the globe top 110.
In order to further enhance the light diffusion capability of the side portion 120, the side portion 120 is optionally doped with light diffusion particles, which may be plastic particles with smaller size, and can further enhance the light diffusion capability, so that the uniformity of the light emitted from the bulb 100 is higher.
Alternatively, in the axial direction of the side portion 120, the thickness of the end portion of the side portion 120 close to the ball top portion 110 is a first thickness, and the thickness of the end portion of the side portion 120 away from the ball top portion 110 is a second thickness, which is greater than the first thickness. That is, the greater the thickness of the portion of the side part 120 farther from the ball top 110, the greater the thickness, the greater the refraction effect of the side part 120 on the light ray, and the greater the refraction angle of the light ray at the side part 120. As described above, the light enters from the first refraction unit and exits from the second refraction unit, and when the side portion 120 is disposed, the light continues to be refracted at the side portion 120, and the refracted light at the side portion 120 is smaller than the included angle between the incident light and the side portion 120, so that by adopting the above technical solution, the refraction degree of the light exiting from the position far away from the top portion 110 of the ball in the side portion 120 is larger, so that the exiting light can further approach the side portion 120, which can further reduce the dark area outside the light source 220 and the bulb 100, and further improve the illumination effect of the light source 220.
Based on the bulb shell 100 disclosed in any of the above embodiments, the embodiment of the present invention further discloses a lamp, the lamp includes the light source module 200 and any of the above bulb shells 100, the light source module 200 includes the light source substrate 210 and the light source 220 disposed on the light source substrate 210, the light source substrate 210 may be connected to an external power source through a wire, or the light source substrate 210 may be connected to a driving power source through a wire, and the driving power source is externally connected to a power source to supply power to the light source 220, the light source 220 may be an LED lamp bead or an LED patch, and the light source substrate 210 is connected to the bulb shell 100, so that the light source module 200 and the bulb shell 100 form a fixed connection. Optionally, the light source module 200 may be adhered to the inner wall of the bulb casing 100 by glue or the like, so that the bulb casing 100 covers the light source 220, on one hand, a certain protection effect is provided for the light source 220, on the other hand, light emitted by the light source 220 can be distributed by the bulb casing 100, and then emitted out of the bulb casing 100, so that the light can be transmitted to one side of the light emitting side departing from the light source 220, and the overall lighting effect of the lamp is improved.
More specifically, the number of the light sources 220 may be at least one, in case of one light source 220, the light source 220 may be centrally disposed with respect to the bulb 100, in case of a plurality of light sources 220, the distribution pattern of the plurality of light sources 220 may be correspondingly designed according to the shape of the bulb 100, for example, in case of a structure in which the top of the bulb 100 is arc-shaped, the plurality of light sources 220 may enclose one or more circular rings. In addition, the light source 220 may be disposed toward the center of the bulb 100, or, in the case of different requirements or different installation positions of the lamp, an included angle greater than zero may be formed between the direction of the light source 220 and the center of the bulb 100, so as to illuminate the predetermined area by the lamp.
As described above, the bulb 100 may include the globe top 110, and the outer surface of the globe top 110 is a spherical structure, and the refraction unit 130 is connected to the inner surface of the globe top 110, based on the above-described structure of the bulb 100, which has been described in detail, and will not be repeated here in view of brevity of text.
