Description

Concentrating collimating optical structure

Technical field

The present invention relates to an optical structure, and more particularly to a concentrating collimating optical structure. Background technique

At present, LED lighting is being used more and more widely due to environmental protection and energy saving, so the market prospect of LED secondary lens is also optimistic. Since the LED has a semi-planar Lambertian shape, it is necessary to use an LED secondary light distribution device to adjust the light during collimation concentrating. The conventional LED secondary light distribution device is a single reflector, or A single lens, the optical components of the former have low reflection efficiency and maintenance coefficient, and there is overflow light around the generated spot, which is not conducive to efficient collimation of light; the light output of the LED optical component with a single lens The efficiency is low, especially in the case of small-angle concentrating collimation, the lens volume is large, which is likely to cause a large amount of material waste and a large increase in production cost.

Summary of the invention

SUMMARY OF THE INVENTION It is an object of the present invention to provide a concentrating collimating optical structure that overcomes the deficiencies of the prior art and which has the advantages of each of the reflector and the lens in collimating light. It can not only improve the reflection efficiency and maintenance coefficient, but also solve the problem of spill light around the spot, save material, reduce production cost, and achieve efficient collimation of light generated by the LED light source with a small beam angle.

In order to solve the above technical problem, the technical solution of the present invention is as follows: A concentrating collimating optical structure includes a reflector base, and a reflector cup body is disposed above the reflector base, the reflector base and the reflector A lens is provided in the middle of the cup.

Preferably, the lens is a Fresnel lens.

Preferably, the reflector base is provided with a lower reflective cavity, and the reflector cup is provided with an upper reflective cavity; the reflector base and the reflector cup are provided such that the reflector base and the reflector are provided The reflector cup is connected, positioned, and coincides with the axis of the reflector cup and the axis of the reflector base First connection positioning device;

The reflector base and the reflector cup are provided with a second connection positioning for mounting the lens and causing the axis of the reflector base and the reflector cup to coincide with the axis of the lens Device

The bottom surface of the reflector base is provided with a vertical positioning connection structure for connecting to the substrate and making the reflector base axis perpendicular to the substrate.

First of all, relying solely on the reflector or reflector to perform secondary light distribution, the effect is relatively poor; for this reason, we have added a lens to improve the effect of secondary light distribution through the lens; in the process of assembly, the reflector The connection between the base and the upper reflector is not only fastened to prevent relative movement of the two, but also the axes must be completely coincident. If there is a problem that the axes are not coincident and the connection is not fast enough, the lower reflector and the lower reflector are The reflective surface formed by the upper reflective cavity affects the surface of the two cavities, which causes a slight misalignment of the faces of the two cavities, which affects the reflection effect of the light emitted by the LED light source, so that the uniformity of the reflected light is poor and the spot is increased, and black holes appear. The yellow circle, the beam angle becomes larger, and the reflection efficiency is lowered; in particular, the problem of non-coincidence of the axis occurs, and it is also possible to interfere with each other after reflection by the lower reflecting cavity and the upper reflecting cavity, if the mold or manufacturing process and assembly are simply used. The process ensures that the fastening connection and the axis of the reflector base and the upper reflector are coincident, and the cost is very high. And the finished product yield will be very low, which will make the product uncompetitive and lose the market; for this purpose, we have set up the first connection positioning device, through the structural setting, the reflector base and the upper reflector are fixedly connected. And the axes coincide.

Secondly, the position and installation of the lens are also very important. The position is calculated and cannot be moved after installation. In particular, axial displacement, radial displacement and axial deflection cannot occur. Once such a situation occurs, It will appear that the axis of the lens and the axis of the upper reflector and the reflector base do not coincide, which will cause the light passing through the lens to deflect, and the axis is not parallel, resulting in poor uniformity of light and increased spot, and black holes and yellow. Circle, the beam angle becomes larger, and at the same time, the light irradiation distance is not far enough, if the precision mold or manufacturing process and assembly process are used to ensure the position of the lens and The axes of the lens, the reflector base and the upper reflector are coincident, the cost will be very high, and the yield will be very low, which will make the product uncompetitive and lose the market. For this reason, we have set the first connection positioning. The device, through the structural arrangement, ensures the coincidence of the axes between the three and the stability of the lens position;

Furthermore, when in use, the reflector bases are all mounted on the substrate, and the substrate is provided

LED lamp bead, in the same way, the axis of the lamp bead coincides with the axis of the reflector base, the axis of the lens and the axis of the upper reflector. Once the axis of the LED bead does not coincide with the axis of the upper three, black holes will still appear. The yellow circle, the beam angle becomes large, and the illumination is not far enough. Moreover, when used, a plurality of LED lamp beads mounted on the substrate are combined and need to be irradiated for a distance of several hundred meters. The base of the reflector is perpendicular to the substrate. Once tilted, the light will not be illuminated, affecting the illumination distance of the entire optical structure. For this reason, we have set up a vertical positioning connection structure to ensure the reflector base from the structure. The axis is perpendicular to the substrate.

In summary, in the entire collimating optical structure, the axes of the lens, the reflector base, and the upper reflector are coincident with each other while being perpendicular to the substrate, and the connection between the reflector base and the upper reflector is fastened. The lens must be mounted securely and the position cannot be moved. These are only guaranteed by molds, machining processes, and assembly methods. The cost is extremely high and the product is not competitive.

Preferably, the vertical positioning connection structure comprises at least two bottom surface positioning pins disposed on a bottom surface of the reflector base and at least two positioning portions; the positioning portion includes a bottom surface of the reflector base a positioning surface, a glue surface for coating the glue flush with the bottom surface of the reflector base, and a glue through hole provided on the glue surface; the bottom positioning pin is disposed on the glue surface.

A bottom positioning pin positioned on the base of the reflector is disposed on the base of the reflector to facilitate connection with the substrate; a positioning portion is used to ensure the vertical between the base of the reflector and the substrate, and glue is applied to the positioning portion, and the base of the reflector is It is bonded and fixed to the substrate. Unlike the conventional screw fixing, it is usually fixed by screws. There are many problems in the force. Once the torque value between the screws is different, the reflector will be caused. The offset of the pedestal, and in actual operation, between the various screws The torque values are equal, the requirements for the workers are very high, the operation is very complicated, and we use glue to bond, there is no such problem. We will locate the part into two parts, one part is used for positioning, that is, the positioning surface, the positioning surface protrudes from the bottom surface of the reflector base, and is in contact with the substrate; the other part is the glue surface, which is used to apply glue, such setting, glue Apply to the glue surface, do not apply on the positioning surface, the positioning surface is fully positioned, it will not cause the position difference due to the application of glue, affecting the verticality of the reflector base, at the same time, the glue is applied on the glue surface, in the bonding When the excess glue can overflow from the side; the reflector base is firmly and accurately fixed, and the position of the reflector base is not offset because the glue is too thick; moreover, the bottom positioning pin is placed on the glue surface. And close to the positioning surface, such an arrangement facilitates the positioning and mounting of the reflector base and the substrate, and enables the reflector base to be perpendicular to the substrate.

Preferably, the reflector base is provided with a ring cavity having an inner side surface, an outer side surface and an upper top surface; the upper surface of the reflector base is provided to communicate with the ring cavity and the glue surface position Corresponding arc-shaped opening; the outer side of the ring cavity is provided with an inwardly extending rubberized plate, and the overflowing through hole and the glue surface are all disposed on the bottom surface of the rubberized plate.

The ring cavity communicates with the bottom surface of the reflector base, and the outer side of the ring cavity is provided with an inwardly extending rubberized plate. The reason why the rubber plate is coated is because it can be used when the force is applied. When the seat is mounted on the substrate, a slight tilt can occur upwards, which does not affect the positioning of the reflector base and the substrate; and the setting of the overflow through hole can overflow the excess glue to prevent the formation of excessively thick glue. The layer affects the positioning and connection of the reflector base and the substrate.

I. The angle of the lower surface of the lower reflecting cavity is 0. 02-0. 05 ° the angle of the lower surface of the lower reflecting cavity. The slanting plate is inclined upwardly from the outer side toward the inner side. It is flush with the bottom surface of the reflector base.

The bottom surface of the lower reflecting cavity is flush with the bottom surface of the reflector base. Because of the processing cost, precision, process, etc., at the lower end of the lowering optical cavity, the surface treatment is relatively poor compared to other parts, and we make the next The bottom surface of the reflective cavity is flush with the bottom surface of the reflector base, in the same horizontal plane, making the LED The light from the lamp bead avoids the bad part and is in contact with the better part; it ensures efficient collimation of the light generated by the LED light source; and after the glue is dried, there is a pull-down force on the glued plate, Avoid the influence of the deformation of the rubberized plate on the positioning of the reflector base and the substrate. We allow the rubberized plate to tilt upward during the extension from the outer side to the inner side to eliminate the deformation of the rubber sheet due to the drying of the glue. The adverse effects.

Preferably, the lens is provided with a fixing bracket for cooperating with the second connecting positioning device, the fixing frame comprises a pair of first supporting plates and a pair of second supporting plates; the second connecting positioning device comprises a pair of first lower positioning mounting ports and a pair of second lower positioning mounting ports disposed on an upper surface of the reflector base; and a pair of first upper positioning mounting ports disposed on a lower surface of the upper reflector Position the mounting port on the second upper.

Preferably, the first support plate surface is provided with an upper inclined plane which gradually increases from the inner side to the outer end surface, and the first upper positioning mounting opening is provided with the outer inclined inner surface matched with the upper inclined plane. Extending the gradually decreasing lower inclined plane.

As mentioned above, in order to ensure the secondary light distribution effect and the sufficient distance of the illumination, the position of the lens is very important when it is installed, and its axis must coincide with the axis of the reflector base and the upper reflector, which cannot occur. A slight deviation, and we set the upper inclined plane and the lower inclined plane, so that at the time of installation, first, the lower inclined plane and the upper inclined plane can play a role of positioning, and the reflective cup base and the upper reflector are fixedly connected. At the same time, the lens is also positioned to overcome the errors generated during processing. To ensure the coincidence of the axes of the three, and secondly, when the lower inclined plane and the upper inclined plane are fitted together, an outward force acts on the first supporting plate, so that the first supporting plate has a slight movement outward, so that the first A support plate can be closely fitted to the first lower positioning mounting opening, and then fixed, and the placement lens is moved or deflected.

Preferably, the end surface of the first support plate is a circular arc surface extending along the circumferential direction of the lens, and the top surface of the first lower positioning mounting opening and the end surface of the first support plate is a circular arc surface.

The first support plate end face and the first lower positioning mounting port top face are not arranged in a rectangular shape or other shape The shape is set to a circular arc surface, so that when the first support plate is installed with a deviation, under the pressure of the lower inclined plane, the two circular arc surfaces are gradually phased by the contact and guiding of the two circular arc surfaces. Fit, to ensure the lens is installed.

Preferably, the second support plate end portion is provided with two lateral fixing plates, a plurality of first inclined plates located between the two lateral fixing plates and arranged from the inside to the outside and intersecting with the first inclined plate a plurality of second inclined plates, wherein the first inclined plate and the second inclined plate form a plurality of first card slots; the lateral fixing plate is provided with a plurality of third inclined plates and the third a plurality of fourth inclined plates intersecting the inclined plates, wherein the third inclined plate and the fourth inclined plate form a plurality of second card slots perpendicular to the first card slot; The first latch and the second latch cooperate with the first slot and the second slot.

In order to ensure the secondary light distribution effect and the far enough illumination, the position of the lens is very important when it is installed. The axis must coincide with the axis of the reflector base and the upper reflector, and no axial movement can occur. Radial position movement and axial rotation. For this purpose, we form a first card slot through the first inclined plate and the second inclined plate, and the first latching teeth cooperate with the first card slot, through the third tilting plate, and the fourth The inclined plate forms a second card slot, and the second latching teeth cooperate with the second latching slot, so that the first latching teeth and the second latching teeth on the upper reflecting cup act in the first card slot and the second card slot a slight deformation of the first card slot and the second card slot, so that the first tilting plate and the second tilting plate are slightly displaced from the inside to the outside, which enables the second supporting plate to be fixed and positioned. Further, a slight displacement occurs in the third inclined plate and the fourth inclined plate, so that the second supporting plate is also fixed and positioned in the other direction, thereby ensuring the position of the lens.

The beneficial effects of the invention are:
