Description

[0001] This application is a divisional application of the invention patent application with the application number 201910741855.2 and the invention title of "Optical Component of a Lighting Lamp and Linear Light Source Lighting Lamp" submitted on August 13, 2019. Technical Field

[0002] The present invention relates to the field of lighting technology, and particularly to a lighting lamp. Background Art

[0003] Currently, LED lamps on the market mainly use point light sources for lighting. Such lighting has problems of glare and reflected glare. To solve the above problems, researchers have tried to use linear light sources to replace point light sources, generally by adding a diffuser cover. This diffuser cover diffuses the light from the LED, but due to the non-uniform diffusion direction, the imaging of the linear light source is messy and blurred. The formed linear light source is directly used to irradiate the irradiated surface, resulting in poor light distribution effect, more energy attenuation, making the formed linear light source dim and messy, and finally the light projected onto the irradiated surface is uneven, leading to poor lighting effect.

[0004] At the same time, existing improved linear light source lamps are either large in size or use a large number of LED lamp particles to achieve the linear light source effect, increasing the production cost. Summary of the Invention

[0070] The following further elaborates on specific embodiments of the present invention based on the accompanying drawings. It should be understood that the description of the embodiments of the present invention herein does not limit the protection scope of the present invention.

[0071] Embodiment 1

[0072] As Figures 1 - 6 shown, the linear light source illuminating lamp of this embodiment includes: a lamp holder 100, a printed circuit board 200, a plurality of point light sources 300, an optical element, and a reflecting wall 600. The optical element includes a lens 400 and a strip-shaped convex lens array 500.

[0073] The lamp holder 100 is used for fixing and installation. It can be assembled from multiple components according to installation needs or can be a single component. In this embodiment, the lamp holder 100 includes two end seats 101, a strip-shaped base 102, and a strip-shaped base 103. The two ends of the strip-shaped base 102 are fixedly connected to the end seats 101. The strip-shaped base 102 is provided with an inner cavity for accommodating the printed circuit board 200, the lens 400, and the reflecting wall 600. The fixing of the printed circuit board 200, the lens 400, and the reflecting wall 600 can be achieved through screws, glue, and snap structures, etc. In this embodiment, the two ends of the strip-shaped base 102 are connected to the end seats 101 and are provided with a strip-shaped first fixing groove 108; the strip-shaped base 103 is arranged at the bottom of the first fixing groove 108 and is provided with a strip-shaped second fixing groove 109 for installing the printed circuit board 200 and the reflecting wall 600. The inner side of the top of the first fixing groove 108 is provided with a first installation groove 105, and the outer side of the reflecting wall 600 is provided with a convex edge 601 that cooperates with the first installation groove 105; the strip-shaped convex lens array 500 is arranged on the top surface of the reflecting wall 600, and the lens 400 is snap-fitted with the strip-shaped base 102.

[0074] A plurality of point light sources 300 are arranged at intervals along the length direction of the linear light source illuminating lamp on the light source installation surface of the printed circuit board 200. Thus, a visual effect of discontinuous point light sources is formed. In the context of energy conservation and environmental protection, LED lamps are increasingly used in the fields of home and commercial lighting due to their high light output efficiency and good light concentration performance. The point light source 300 uses an LED chip.

[0075] In this embodiment, the optical axis direction of the point light source 300 is set as the z direction, the installation surface of the point light source 300 is a plane perpendicular to this z direction. On the installation surface, the arrangement direction of the point light sources 300 is the x direction, and the direction perpendicular to the x direction is the y direction. The printed circuit board 200 is also arranged on this installation surface. The xyz coordinate system can define the xy plane, the yz plane, and the xz plane.

[0076] The lens 400 is disposed on the lamp holder 100. The quantity can be set according to the desired light distribution effect, and it can be one or multiple. Generally, a single lens can achieve the required light distribution effect. Specifically, it is snap-fitted and connected to the strip-shaped base 102, located in the light-emitting direction of the point light source 300, and is used to adjust the light distribution of the point light source 300 in the plane (yz plane) perpendicular to the length direction of the linear light source illumination lamp. The dimming in a single plane enables the lens 400 to be easily manufactured, and it can be manufactured through an extrusion process. Since the light of the LED chip itself is unevenly distributed, this will cause the linear light source formed after imaging by the strip-shaped convex lens array 500 to have regions with stronger and weaker brightness. It is easy to understand that the light energy emitted from the region with weaker brightness is weaker, and the light energy emitted from the region with stronger brightness is stronger. In order to make the finally emitted light evenly distributed, the lens 400 preferably adopts an asymmetric lens. The light from the region with weaker brightness of the linear light source is emitted from the part with stronger light-gathering ability of the asymmetric lens, while the light from the region with stronger brightness is emitted from the part with weaker light-gathering ability of the asymmetric lens. In this way, the effect of consistent illumination of the emitted light can be reasonably achieved. However, this does not mean that the lens 400 can only adopt an asymmetric form. In fact, a symmetric form can also be adopted. Only in this case, the brightness at both ends of the linear light source is brighter, and the brightness is weaker towards the middle position. When the lens 400 adopts a symmetric lens, the middle protruding part of the lens 400 corresponds to the middle position of the linear light source, and both ends correspond to both ends of the linear light source, and in this way, the uniformity of the light can also be achieved. In addition, the lens 400 can also adopt the form of an optical thin film. When the lens 400 adopts an optical thin film, the lens 400 and the strip-shaped convex lens array 500 are integrated on the same optical thin film. This optical thin film stretches the point light source into a linear light source in the x direction and controls the light distribution of the point light source in the yz plane.

[0077] The strip-shaped convex lens array 500 is disposed on the lamp holder 100, located between the lens 400 and the printed circuit board 200 and arranged along the length direction of the linear light source illumination lamp, and is used to convert each point light source 300 into a plurality of continuous sub-point light sources. The sub-point light sources converted from adjacent point light sources 300 are butted or overlapped. It can be seen that before using the strip-shaped convex lens array 500, the point light source 300 remains a point light source after passing through the lens 400, while after adding the strip-shaped convex lens array 500, it becomes a linear light source, as Figure 2 shown.

[0078] The strip convex lenses in the strip convex lens array 500 can be in the planar form of a positive cylindrical lens or in the curved surface form that is curved in the length direction of the strip convex lens. The required effect is to stretch the point light source 300 in the arrangement direction (x direction) of the point light sources, so that the point light sources form a line light source, and at the same time minimize or eliminate the influence on the point light source 300 in other directions. The cross-sectional size of the strip convex lens can be set as required. The strip convex lens array 500 can be obtained by processing techniques such as 3D printing, extrusion, or injection molding. By adjusting the curvature and radius of the strip convex lens, controlling the distance between the strip convex lens array 500 and the point light source 300, and the spacing between adjacent point light sources 300, the strip convex lens array 500 can also use existing optical films to achieve the same effect. In this embodiment, the strip convex lens array 500 is a positive cylindrical lens microarray provided on an optical film. Specifically, the optical film is an elliptical light diffusing film, and the model used is E-6010. Of course, other models can also be selected as long as the point light source 300 is stretched in the arrangement direction (x direction) of the point light sources, such as E-1560, E-0160 / 6001, E-0190. In order to achieve a better stretching and diffusing effect, when selecting this diffusing film, the stretching ratio in the two directions is greater than 4. The elliptical light diffusing film in this embodiment is a positive cylindrical microlens array. When in use, the length direction of the positive cylindrical microlens is perpendicular to the arrangement direction (x direction) of the point light source 300. The strip convex lens array 500 in the form of a film is small in volume, easy to install, and can be bent to adapt to the structural requirements of different lamps.

[0079] In order to further improve the light utilization rate of the LED lamp, on the plane perpendicular to the length direction of the line light source illumination lamp, reflection walls 600 for reflecting the lateral light from the point light source 300 to the incident surface of the strip convex lens array 500 are provided on both sides of the point light source 300. Of course, the absence of the reflection walls 600 does not affect the use of the line light source illumination lamp, that is, the reflection walls 600 are not essential functional components. The upper ends of the reflection walls 600 extend to the bottom surface of the strip convex lens array 500. The point light source 300 is arranged on the printed circuit board 200, and most of its light is emitted in the direction towards the strip convex lens array 500, but there will also be a small amount of lateral light that deviates from the main beam and is emitted in other directions, and this type of light is often not utilized, resulting in a reduction in the effective utilization rate of light. This is a common problem existing in the radial emission of the light source light. When adopting the above design, the reflection effect can be well utilized to guide the originally deviated lateral light to the strip convex lens array 500 as well, thereby concentrating the light beam, having more light flux actually diffused and formed by the strip convex lens array 500 per unit area, improving the effective utilization rate of light, reducing the number of point light sources 300 provided, and reducing costs.

[0080] Meanwhile, in order to guide as much of the deflected light as possible towards the direction of the strip convex lens array 500, according to the principle of the light propagation path and the light radiation angle of the point light source 300, in this embodiment, an obtuse angle is provided between the reflection wall 600 and the printed circuit board 200, and the specific angle is adjusted according to the distance between the point light source 300 and the strip convex lens array 500.

[0081] Embodiment 2

[0082] As Figure 7 and 8 shown, the main components and the positional relationship of the linear light source illuminating lamp in this embodiment are the same as those in Embodiment 1, the difference being the shape of the lens 400 and the connection manner of each component.

[0083] In this embodiment, the lens 400, the reflection wall 600 and the strip base 103 are integrally formed to form an installation cavity 104 that is closed in cross-section. The integral formation can adopt an extrusion process. Among them, the lens 400 is a symmetric lens and has a change in curvature on both the inner and outer surfaces, which is easier to process and manufacture. In the installation cavity 104, a first installation groove 105 for fixing the strip convex lens array 500 is provided near the lens 400, and a second installation groove 106 for fixing the printed circuit board 200 is provided at the bottom of the installation cavity 104. The two side walls between the first installation groove 105 and the second installation groove 106 are the reflection walls 600. The reflection wall 600 with an arc-shaped structure enables a smaller reflection angle and higher efficiency.

[0084] The strip base 102 is made of a metal with better heat dissipation effect and is provided with an arc-shaped installation groove for fixing the strip base 103. The bottom surface of the strip base 103 is an arc-shaped surface that fits the arc-shaped installation groove, thereby improving the heat dissipation effect.

[0085] The strip convex lens array 500 in this embodiment also uses an elliptical light diffusion film, and both sides in the width direction are inserted into the first installation groove 105 for assembly.

[0086] Embodiment 3

[0087] As Figure 9 and 10 shown, the main components and the positional relationship of the linear light source illuminating lamp in this embodiment are the same as those in Embodiment 1, the difference being the shape of the lens 400 and the connection manner of each component.

[0088] In this embodiment, the reflection wall 600 and the strip base 103 are integrally formed. On the inner sides of the tops of the two reflection walls 600, a first installation groove 105 for fixing the strip convex lens array 500 is provided. On the outer sides of the tops of the two reflection walls 600, a snap structure for fixing the lens 400 is provided. At the bottom of the strip base 103, a second installation groove 106 for fixing the printed circuit board 200 is provided.

[0089] The strip-shaped convex lens array 500 in this embodiment also uses an elliptical light diffusing film, and is assembled by inserting both sides in the width direction into the first mounting groove 105.

[0090] In this embodiment, the lens 400 is a polarizing lens, which is used to adjust the light distribution of the point light source 300 in the plane (yz plane) perpendicular to the length direction of the linear light source illuminating lamp. In the perspective shown in the figure, the light output is polarized to the left.

[0091] Embodiment 4

[0092] As Figure 11 shown, except for the installation, connection and positional relationship of the strip-shaped convex lens array 500 and the lens 400 being different, the structures and connection methods of the remaining components in this embodiment are the same as those in Embodiment 1. The strip-shaped convex lens array 500 and the lens 400 are integrally formed, and the strip-shaped convex lens array 500 is arranged on the light-emitting surface of the lens 400.

[0093] Embodiment 5

[0094] As Figures 12 - 14 shown, in this embodiment, like Embodiment 4, the strip-shaped convex lens array 500 and the lens 400 are integrally formed.

[0095] The linear light source illuminating lamp in this embodiment includes a lamp holder 100, a printed circuit board 200, a plurality of point light sources 300, a lens 400, a strip-shaped convex lens array 500, and a lamp shade 800.

[0096] The lamp holder 100 includes a first strip-shaped base 111 and a second strip-shaped base 112 separated by a partition fixing plate 110. Two printed circuit boards 200 provided with a plurality of point light sources 300 are symmetrically arranged and are respectively installed in the first strip-shaped base 111 and the second strip-shaped base 112. Correspondingly, there are two symmetric lenses 400, which are respectively installed in the first strip-shaped base 111 and the second strip-shaped base 112. The outer sides of the first strip-shaped base 111 and the second strip-shaped base 112 are connected to both sides of the lamp shade 800 through a snap structure. The outer side surfaces of the snap structures 801 provided on both sides of the lamp shade 800 are provided with soft glue 802, and the soft glue 802 is in interference connection with the inner side walls of the first strip-shaped base 111 and the second strip-shaped base 112. In this embodiment, the side of the soft glue 802 facing the inner side wall of the strip-shaped base is provided with serrations 803. The setting of the serrations 803 can increase the contact tightness between the soft glue 802 and the inner wall of the strip-shaped base, thereby playing a good waterproof role.

[0097] The lens 400 includes a light-transmitting main part 401 for focusing and emitting most of the light of the point light source 300 and a light-transmitting auxiliary part 402 arranged at a certain angle with one side of the light-transmitting main part 401 to guide a small part of the light of the point light source 300 to be emitted.

[0098] The light-transmitting main part 401 guides and projects most of the light to the far end of the illumination surface 700, and the light-transmitting auxiliary part 402 guides and projects a small part of the light to the near end of the illumination surface 700. On the plane perpendicular to the length direction of the linear light source illuminating lamp, the included angle formed by the incident surface of the light-transmitting auxiliary part 402 and the incident surface of the light-transmitting main part 401 is 90° to 160°.

[0099] As Figure 13 shown, the distance between the light-transmitting auxiliary part 402 and the point light source 300 is farther than the distance between the light-transmitting main part 401 and the point light source 300. That is, the light-transmitting auxiliary part 402 is farther from the point light source 300, and the incident surface is provided with a strip-shaped convex lens array 500; the light-transmitting main part 401 is closer to the point light source 300. In order to improve the effect of presenting a linear light source, both the incident surface and the exit surface are provided with a strip-shaped convex lens array 500.

The shape of the lens 400 can be designed according to needs and can be a symmetric convex lens, a polarizing lens or a special-shaped lens.

[0103] As Figure 16 shown, in this embodiment, the lens 400 is located between the strip-shaped convex lens array 500 and the printed circuit board 200, and the strip-shaped convex lens array 500 is set as a lamp shade. In this embodiment, the strip-shaped convex lens array 500 is a curved surface that is curved in the length direction of the strip-shaped convex lens.

The cooperation of the two lenses 400 can achieve a higher requirement for light distribution. The shape of the lens 400 can be designed according to needs and can be a symmetric convex lens, a polarizing lens or a special-shaped lens.
