For those of ordinary skill in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0044] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0045] like Figure 1-2As shown, the present application relates to a lens assembly, a light source module and a lighting device. The lens assembly includes: a substrate 10; the substrate 10 refers to a basic plate material, which can achieve good fixing and supporting effects; at the same time, it can also cooperate with other components to achieve multiple functional effects. It should be noted that the substrate material includes but is not limited to: optical glass or plastic, such as: polymethyl methacrylate (PMMA), polycarbonate (PC), etc., which is not limited in this application.

[0046] A lens 20 with a directional curved surface is arranged on the upper surface of the substrate 10; by setting the outer surface of the lens 20 to have a directional curved surface, the lens 20 with a specific curved surface shape and optical performance can achieve a specific optical effect through precise curved surface shape and refractive index.

[0047] A plurality of lamp beads 30 are arranged in an array in sequence in the lens 20; by providing a plurality of lamp beads 30, a good lighting effect can be achieved; at the same time, it can also be coordinated with other components to achieve the effect of multiple display states. Preferably, the lamp beads 30 are LED (light emitting diode) lamp beads 30, which are solid-state semiconductor devices that can convert electrical energy into visible light.

[0048] Of course, it is also possible to realize LED lamp beads 30 of different colors, from red, green, blue to white light and other colors, by controlling the characteristics of semiconductor materials.

[0049] It should be noted that the internal core of the LED lamp bead 30 is a PN junction composed of two semiconductor materials, in which the P region (positive charge region) is rich in positive charges (holes), and the N region (negative charge region) is rich in negative charges (electrons). When the LED lamp bead 30 is connected through an external circuit and current is passed through it, the positive electrode (anode) and the negative electrode (cathode) will inject electrons and holes into the PN junction, and electrons will flow from the N region to the P region, while holes will flow from the P region to the N region. This process is called electron injection.

[0050] Near the PN junction, electrons and holes will recombine. During recombination, the energy of electrons and holes is released and converted into photons (the basic unit of light). This phenomenon is called radiative recombination. The energy of photons is related to the energy gap of the material. Different energy gaps of materials produce different colors of light. These photons will propagate along the lattice structure of the LED material, generating visible light, thereby realizing the conversion of electrical energy into light energy.

[0051] Among them, a plurality of the lamp beads 30 are arranged in a three-row and two-column array in a lens 20 to form a minimum optical lens unit 40. By arranging the plurality of lamp beads 30 in a three-row and two-column structure, it is possible to light up or turn off the lamp beads 30 in different rows through different control instructions, thereby forming a variety of light distribution curves, and thus achieving the effect of easy operation and adjustment.

[0052] From the above description, it can be seen that the present application achieves the following technical effects:

[0053] In the embodiment of the present application, a preset optical lens 20 structure and an adjustable light distribution curve are adopted, through a substrate 10; a lens 20 with a directional curved surface is arranged on the upper surface of the substrate 10; and a plurality of lamp beads 30 are arranged in an array in sequence in one of the lenses 20; wherein the plurality of the lamp beads 30 are arranged in an array in the form of three rows and two columns in one of the lenses 20 to form a minimum optical lens unit 40; a circuit board 70 is arranged at the bottom of the substrate 10, and a plurality of groups of lamp bead modules formed by a plurality of the lamp beads 30 are arranged on the circuit board 70, and the plurality of groups of the lamp beads The modules are respectively embedded in the multiple rectangular grooves 50, and the multiple groups of lamp bead modules are respectively located in the multiple lenses 20, so that the purpose of adjustable light distribution curve is achieved, thereby realizing the technical effect of convenient adjustment operation and cost reduction, and further solving the problem that the mechanical type needs to use tools to achieve part displacement, which not only increases the difficulty of lamp protection and material cost, but also may bring additional uncontrollable risks due to protection failure; the multiplication type needs to increase the number of lenses 20 and LEDs, which not only directly increases the material cost, but also may bring additional uncontrollable risks due to increased lamp size and weight.

[0054] Furthermore, the number of the optical lens units 40 is multiple, and the multiple optical lens units 40 are sequentially arranged in an array at intervals on the upper surface of the substrate 10;

[0055] Among them, the plurality of optical lens units 40 adopt a rectangular array. It can be understood that by arranging a plurality of optical lens units 40 in an orderly array on the upper surface of the substrate 10 and adopting a rectangular array structure, the light emitted by the light source can form uniform illumination on the target plane, thereby improving the visibility and clarity of the image or object.

[0056] Preferably, the rectangular array has a structure of four rows and four columns; by adopting the four rows and four columns structure, good uniform illumination, beam shaping and image projection effects can be achieved.

[0057] Furthermore, the optical lens unit 40 is provided with a rectangular groove 50 on one side close to the light incident curved surface. It is understandable that by providing the rectangular groove 50 at the bottom of the substrate 10 and around the optical lens unit 40, a good matching effect with other components can be achieved, thereby ensuring a precise assembly effect. Preferably, the area of ​​the rectangular groove 50 is at least larger than the area of ​​the optical lens unit 40, which can ensure a good chimeric assembly effect.

[0061] Specifically, the cone 60 has a right-angled triangle cross-sectional area, which can achieve good optical coordination with the optical lens unit 40. At the same time, the height of the cone 60 is at least not less than the height of the optical lens unit 40, which can avoid affecting the optical performance while ensuring good optical performance.

[0062] The utility model provides a method of combining optical technology with control technology to realize an LED light source module in which the lens 20 achieves three (or more) different optical light distribution curves of TP2, TP3, and TP4 through the combination of optical design and circuit design, without relative displacement between the LED light source and the lens 20 and without replacing the lens 20.

[0063] The light source module has the function of adjusting the on and off of lamp beads 30 at different positions through circuit control. The lamp beads 30 are combined with a fixed corresponding position optical lens 20 arc surface to realize different optical light distribution curves to achieve a method in which an optical lens 20 is compatible with multiple light type designs.

[0064] Through the adjustment of the above technical methods, without increasing the number of lenses 20, the different curved surfaces of multiple groups of LED lenses 20 can be controlled to achieve intelligent switching of working states of various optical curve light distribution applications.

[0065] The light source module of the utility model can completely solve the problems brought by the existing technology, such as cumbersome operation, protection failure, increased cost, size and weight, and potential safety hazards. Not only is the adjustment operation more intelligent and simple, but it also does not cause other cost increases. Most importantly, it is safe and reliable and does not cause any other dangers.

It can be understood that by providing the circuit board 70 at the bottom of the substrate 10, a good electrical control effect can be achieved, thereby achieving a good control effect on the lighting or extinguishing of the plurality of groups of lamp bead modules. The circuit board 70 is located at the bottom of the light source module. The material of the lower substrate includes but is not limited to: aluminum base, copper base, FR4, etc.; the insulating layer is made of a material with a high thermal conductivity coefficient, which effectively improves the heat dissipation efficiency.

[0067] Preferably, the circuit board 70 may be a PCB board; various components may be installed or printed on the PCB board, thereby achieving good integration and electrical control effects.

[0068] Of course, other components including but not limited to the following may also be provided: a microcontroller (MCU) or microprocessor, which is the core control unit in the multiple lamp beads 30 module, responsible for processing signals from external inputs (such as switches, sensors, remote controls, etc.), and controlling the operation of the LED circuit board 70 according to a preset program or algorithm. The MCU / microprocessor can receive a PWM (pulse width modulation) signal to adjust the brightness of the LED.

[0069] LED driver, LED driver is an electronic circuit connected between LED and power supply, which is responsible for converting the direct current (DC) voltage or alternating current (AC) voltage of the power supply into the current and voltage required by the LED.

[0070] Sensors, such as light sensors, temperature sensors, motion sensors, etc., can change the behavior of the LED based on the environment or user interaction.

[0071] Protection circuit: The protection circuit is used to prevent LED and other circuit components from being damaged by overvoltage, overcurrent, overheating, etc.

[0072] By respectively embedding a plurality of groups of the lamp bead modules in a plurality of the rectangular grooves 50, a good assembly effect can be achieved, and at the same time, a precise positioning effect can be achieved, thereby ensuring good optical performance.

[0073] like Figure 5-7 As shown, specifically, by providing multiple arc surfaces of optical lenses 20 with special structures, six LED lamp beads 30 can be placed in three rows and two columns inside each arc surface of the optical lens 20, and corresponding light distribution curves are generated according to different positions of the lit LED lamp beads 30;

[0074] For example: when the first two rows of LED lamp beads 30 are working, a Type 2 light distribution curve is generated; when the last two rows of LED lamp beads 30 are working, a T4 light distribution curve is generated; when all three rows of LED lamp beads 30 are working, a T3 light distribution curve is generated.

[0075] Furthermore, multiple groups of the lamp bead modules are electrically connected through the conductive circuit 80; multiple groups of the lamp bead 30 modules are electrically connected in a hybrid manner; wherein the circuit board 70 sends a control signal according to the received command signal, and controls the lamp beads 30 of the designated rows to light up or turn off, so that the minimum optical lens unit 40 has a plurality of modes of light distribution curves. It is understandable that by providing the conductive circuit 80, it is possible to achieve the effect of electrically connecting multiple groups of the lamp bead modules, thereby ensuring a good electrical signal transmission effect, and further providing a guarantee for subsequent electrical control. Preferably, the conductive circuit 80 is a copper foil circuit; the copper foil circuit is located on the upper part of the circuit board 70.

The hybrid design can also effectively avoid the failure of the entire light source module due to the failure of a single LED. Of course, as a person skilled in the art, the principle of the electrical schematic diagram shown in this application should be known.

[0078] The LEDs are welded on the circuit board 70 and can have the same or multiple different color temperatures according to needs. Six LEDs are arranged in three rows and two columns under the arc surface of each optical lens 20 .
