[0037] In the related art, lawn mower lamps, as outdoor lamps, do need to withstand various adverse weather conditions, especially the invasion of rain. Therefore, the waterproofness of the light-emitting module of lawn mower lamps is a crucial aspect in their design. The light-emitting modules of lawn mower lamps are mostly LED lamp beads, which are also called high color gamut CSP (Chip Scale Package) lamp beads. Since the package size of high color gamut CSP (Chip Scale Package) lamp beads is close to the chip size and the structure is compact, it is usually necessary to pay more attention to protective measures in design and material selection, especially to prevent moisture intrusion, so as to ensure its stable operation in complex environments. Due to its relatively large surface area to volume ratio, it is easily affected by high temperature and high humidity. Specifically, in terms of water vapor sensitivity, if the sealing of CSP lamp beads is insufficient, moisture is more likely to penetrate into the package in a high temperature and high humidity environment, which will not only reduce the luminous efficiency, but also may cause chemical reactions in the internal materials, such as oxidation of the lead frame and bracket coating, and even cause electrical short circuits between the chip and the packaging material, seriously affecting its performance and reliability.

[0038] In the related art, sealant is mostly applied to the assembly gap of the light-emitting module. However, since the lawn mower lamp is assembled from multiple parts, there are still dead corners for sealing, which affects the waterproof performance of the lawn mower lamp, is not conducive to extending the service life, and affects the quality of the product.

[0039] like Figure 1 , Figure 3 and Figure 4 As shown, in order to solve the above technical problems, an embodiment of the present application provides a light-emitting module, which includes an optical light cup 400, a lamp bead 600, a circuit board 700 and a light-transmitting packaging adhesive layer 500, the lamp bead 600 is connected to the circuit board 700, and the circuit board 700 is installed at the bottom end of the optical light cup 400; the light-transmitting packaging adhesive layer 500 is filled in the light cup.

[0040] In this embodiment, the lamp bead 600 takes the LED lamp bead 600 as an example. The LED lamp bead 600 is electrically connected to the circuit board 700. The circuit board 700 is fixed to the bottom end of the optical light cup 400 by screws or adhesives. The optical light cup 400 has a relative open end and a bottom end. The open end is for the light emitted by the LED lamp bead 600 to be emitted after being adjusted by the optical light cup 400.

[0041] For example, the optical light cup 400 is set to be cylindrical, and the open end of the optical light cup 400 is set to be flared, the bottom end of the optical light cup 400 is set to be a threading hole, and the circuit board 700 is fixed to the bottom end of the optical light cup 400 by screws; of course, in other embodiments, the optical light cup 400 can also be set to other shapes. For example, in addition to the traditional circular, elliptical or conical design, the optical light cup 400 can be set to a variety of other shapes according to the application scenario requirements to meet different lighting goals and performance improvement. The following are some examples: Rectangular light cup, suitable for linear light beams, such as linear lighting, runways, indicator lights, signs, to improve directionality. Elliptical, adjust the light beam, the light spot is more uniform, suitable for floodlighting and surface lighting, such as offices and exhibition halls. Free-form surface light cup, adapt to special designs, such as sculptures, artistic lighting, personalized spaces, and unique light effects. Polygonal light cups, such as hexagonal and octagonal, beam angle light spots, are used for special effects to highlight the sense of design. Gradient focus light cup, high light intensity at both far and near, one light for multiple uses, such as stage and studio. Combination light cups, such as double light cups, nested stacking, composite light effects, complex light effects, such as landscape and architectural lighting, etc. No specific limitation is given here. The selection of the shape of the optical light cup 400 is based on comprehensive consideration of light effect requirements, application scenarios, space design, beam angle, and uniformity requirements. Through computer simulation design and optical simulation optimization, the optimal light distribution is achieved to meet the lighting design requirements.

[0042] Among them, after the circuit board 700 and the lamp bead 600 are installed in the optical light cup 400, a light-transmitting packaging glue is dripped from the open end of the optical light cup 400 to form a light-transmitting packaging glue layer 500 in the optical light cup 400. Since the light-transmitting packaging glue layer 500 is light-transmitting, it will not affect the emission of light from the optical light cup 400. Of course, setting a translucent encapsulation glue layer 500 in the optical light cup 400 has the following effects: the translucent encapsulation glue layer 500 has a high transmittance, reduces light loss, optimizes reflection within the light cup, and improves total light extraction, brightness, and light transmission effect; the light translucent encapsulation glue layer 500 is moisture-proof, weather-resistant, sealed, dust-proof, and anti-aging, which is conducive to outdoor use, extends the life, and protects the LED; the glue of the translucent encapsulation glue layer 500 is thermally conductive, and part of the glue is thermally conductive, which helps to dissipate heat, reduce junction temperature, protect the chip, and improve light attenuation and thermal stability; the translucent encapsulation glue layer 500 has shock and impact protection functions, and can fix components, enhance structure, prevent displacement, protect the light cup and stabilize the light beam; and the translucent encapsulation glue layer 500 has an adjustable refractive index, changes the light path and beam angle, and optimizes the light type, just like a lens sheet, which can enhance light distribution.

[0043] When the light-emitting module provided by the present application is used, a light-transmitting packaging glue can be directly injected into the optical light cup 400 to form a light-transmitting packaging glue layer 500 in the optical light cup 400, and then the lamp beads 600 and the circuit board 700 can be directly packaged in the optical light cup 400, so that the sealing effect is better, and the assembly is simplified, the parts are reduced, the stability is improved, the automation is facilitated, the cost is reduced, and the production efficiency is improved; through the light cup and the light-transmitting glue layer, the light beam is optimized, the light intensity is controlled, the lighting efficiency and the uniformity of the lighting are improved, and the light waste is reduced; and the glue layer is sealed, and has the characteristics of moisture-proof, dust-proof, and shock-proof, and can extend the life, protect electronic components, and adapt to outdoor and harsh environments.

[0044] In addition, by optimizing the optical light cup 400 and the waterproof and light-transmitting encapsulation adhesive layer 500, it is possible to reduce unnecessary directional light loss, allow light to illuminate the desired direction, and increase light utilization, thereby indirectly achieving the purpose of lighting energy saving and meeting the green energy demand for energy saving.

[0045] like Figure 4 As shown, in some embodiments, the beam angle of the optical light cup 400 is A, satisfying: A≤90°.

[0046] In this embodiment, the optical light cup 400 is designed to control the direction and diffusion of light, and its beam angle A is not greater than 90 degrees. This angle range ensures that the light can be effectively gathered or directed, and is suitable for scenes that require precise lighting control. For example, in this application, it is applied to a lawn mower lamp.

[0047] Exemplarily, the beam angle of the optical light cup 400 is 90°; of course, in other embodiments, the beam angle of the optical light cup 400 may also be 88°, 86°, 84°, 82°, 80°, 78°, 76°, 74°, 72°, etc., which is not specifically limited here.

[0048] like Figure 4 As shown, in some embodiments, the circuit board 700 has a pin 710 , and the pin 710 is located at one end of the circuit board 700 facing the opening end of the optical light cup 400 .

[0049] It is easy to understand that the circuit board 700 and the lamp bead 600 are mostly fixedly connected in the following ways: Welding technology: LED lamp bead 600 is usually connected to the circuit board by gold wire welding. The gold wire is several microns in size and requires high-precision welding technology to ensure stability. Glue point connection: Apply conductive glue on the board to fix the LED lamp bead 600. Conductive glue is bonded to improve reliability, but the cost is slightly higher.

[0050] Among them, the pins 710 on the circuit board 700 are divided into positive pins 710 and negative pins 710, and then the positive pins 710 and the negative pins 710 are connected to a power source to supply power to the LED lamp bead 600.

[0051] Obviously, in the present application, the pin 710 is arranged on the side of the circuit board 700 facing the open end of the optical light cup 400, so that the light-transmitting packaging glue layer 500 can cover the pin 710, thereby achieving a moisture-proof and humidity-proof effect on the pin 710, which is beneficial to reduce the probability of chemical reactions of internal materials, such as oxidation of the lead frame and bracket coating, and even causing an electrical short circuit between the chip and the packaging material, etc.

[0052] In some embodiments, a wetting glue is pre-coated on the surface of the lamp bead 600 to form a light-transmitting wetting glue layer on the surface of the lamp bead 600, and then a packaging glue is dripped on the outside of the light-transmitting wetting glue layer to form a light-transmitting packaging glue layer 500 on the outside of the light-transmitting wetting glue layer. It should be noted that the location of dripping the packaging glue can be controlled by a glue dispenser.

[0053] Among them, when applying the wetting glue, the wetting glue can enter the gaps between the lamp bead 600, the circuit board 700, and the lamp bead 600, thereby achieving pre-filling. For example, the wetting glue has low viscosity, low thixotropy, high adhesion, and high sealing, which can not only enhance the sealing of the lamp bead 600, but also ensure that the wetting glue can be filled into the gap. In other words, by pre-coating a light-transmitting wetting glue layer on the surface of the lamp bead 600, the affinity of the light-transmitting encapsulation glue layer 500 and the surface of the lamp bead 600 can be utilized to make the light-transmitting wetting glue layer and the light-transmitting encapsulation glue layer 500 blend, effectively reducing the probability of bubbles; in addition, the light-transmitting wetting glue layer can be applied to enhance the sealing of the lamp bead 600, form a first protective layer, and cooperate with the second protective layer formed by the light-transmitting encapsulation glue layer 500, which can effectively reduce the influence of moisture on the lamp bead 600 and improve the service life and quality.

[0054] Exemplarily, the light-transmitting wet adhesive layer is a silicone layer with low viscosity, high fluidity, high refractive index and high transmittance, which is applied to the side of the lamp bead 600 before applying the lens glue to reduce bubbles and improve optics.

[0055] like Figure 2 and Figure 3 As shown, in some embodiments, the light-transmitting encapsulation adhesive layer 500 is fully filled in the optical optical cup 400 , so that the light-transmitting encapsulation adhesive layer 500 forms an optical lens.

[0056] In these embodiments, the light-transmitting encapsulation glue layer 500 not only serves as protection and fixing, but is also deliberately filled into the optical light cup 400 to form an integral optical lens surface, which has the following characteristics:

[0057] Integrated optical design, the light-transmitting encapsulation adhesive layer 500 is not only an encapsulation, but also forms a mirror surface, which is integrated with the optical light cup 400, optimizes the light cup design, simplifies the structure, and improves the overall light efficiency;

[0058] The light-transmitting encapsulation adhesive layer 500 on the lens surface has high light transmittance and acts as a lens to control the light beam, reflect and refract, and cooperate with the light cup design to optimize light output, light type and uniformity;

[0059] It should be noted that the glue layer injection process is easy to automate, quickly solidifies, controls quality, improves production efficiency, reduces costs, and is suitable for large-scale production.

[0060] In summary, this design enables the light-transmitting encapsulation adhesive layer 500 to not only play a protective role, but also integrate into the overall design as a part of the optical system, thereby optimizing the light output, enhancing the system performance, and adapting to high-demand lighting application environments.

[0061] For example, the shape of the light-transmitting encapsulation adhesive layer 500 is compatible with the internal contour of the optical light cup 400. For those skilled in the art, since the light-transmitting encapsulation adhesive layer 500 is formed by dripping adhesive into the optical light cup 400, it is easy to control the shape of the light-transmitting encapsulation adhesive layer 500.

[0062] In some embodiments, the light-transmitting encapsulation adhesive layer 500 is a light-transmitting silicone layer.

[0063] The use of a light-transmitting silicone layer can ensure light penetration, low attenuation loss, high refractive index, and low light loss, especially for LED applications.

[0064] In addition, the light-transmitting silicone layer is resistant to high and low temperatures, UV rays, and humidity, is stable outdoors, does not change color, has a longer service life, and is anti-aging, making it suitable for use in outdoor lighting, display, and other fields.

[0065] Of course, in other embodiments, epoxy resin, acrylate, urethane, polyurethane, polycarbonate, etc. may also be selected, without specific limitation herein, as long as the same technical effect can be achieved.

[0066] like Figure 3 and Figure 4 As shown, an embodiment of the present application further provides a lamp, which includes any light-emitting module in the above embodiments.

[0067] Since the above-mentioned light-emitting component has the above-mentioned technical effects, the lamp including the light-emitting component should have the same technical effects, which will not be repeated here.

[0068] like Figure 3 and Figure 4 As shown, in some embodiments, the lamp further includes a lamp housing 100 , and the lamp housing 100 and the optical light cup 400 are integrated.

[0069] In this embodiment, the lamp housing 100 and the optical light cup 400 are formed by an integrated molding process, which reduces the number of parts and assembly difficulty, so as to make the outdoor use more reliable. Obviously, setting the optical light cup 400 as an integrated structure is beneficial to the heat conduction efficiency between the optical light cup 400 and the lamp housing 100, thereby enhancing the heat dissipation efficiency of the lamp.

[0070] Of course, in other embodiments, the lamp housing 100 and the optical light cup 400 may be configured as a split structure according to specific usage scenarios.

[0071] like Figure 1 , Figure 3 and Figure 4As shown, in some embodiments, the lamp housing 100 has a relative front end 110 and a rear end 120; wherein the lamp housing 100 is a heat-conducting member, the optical light cup 400 is located at the front end 110, and the rear end 120 is provided with a plurality of heat dissipating fins 200, and the heat dissipating fins 200 and the lamp housing 100 are integrated.

[0072] In this embodiment, the lamp housing 100 is provided with heat dissipation fins 200 so that the lamp housing 100 has a heat dissipation structure, which is beneficial to the rapid heat dissipation of the lamp; wherein, since the lamp housing 100 and the optical light cup 400 are integrated, the heat can be further conducted to the heat dissipation fins 200 .

[0073] Exemplarily, a plurality of heat dissipation slots are provided at the rear end 120 of the lamp housing 100 , thereby forming a plurality of heat dissipation fins 200 .

[0074] For example, the lamp housing 100 is made of metal material, which can not only improve the structural strength of the lamp, but also help enhance the thermal conductivity and heat dissipation performance of the lamp housing 100 .

[0075] Exemplarily, the lamp housing 100 and the optical light cup 400 are made by an integrated aluminum alloy molding process.

[0076] like Figure 3 and Figure 4 As shown, an embodiment of the present application further provides a lighting device, and the lighting device includes any lamp in the above embodiments.

[0077] Since the above-mentioned light-emitting component has the above-mentioned technical effects, the lamp including the light-emitting component should have the same technical effects, which will not be repeated here.

[0078] like Figure 3 and Figure 4 As shown, in some embodiments, the lighting device further includes a lighting device body, the lighting device body has a plurality of installation cavities, and the lamp is inserted into the installation cavity, and a radial seal is arranged between the lamp housing 100 of the lamp and the inner wall of the corresponding installation cavity.

[0079] That is to say, the lighting device body of the lighting device can be provided with the number of installation cavities as required, and then a lamp can be installed in each installation cavity.

[0080] Exemplarily, the number of the mounting cavities is 1; of course, in other embodiments, the number of the mounting cavities may also be 2, 3, 4, 5, 6, and so on.

[0081] Wherein, providing a radial seal between the lamp and the inner wall of the installation cavity can further enhance the sealing performance of the lamp.

[0082] Exemplarily, the mounting cavity is configured as a cylindrical hole, the outer shell of the lamp is configured as a cylinder, an annular groove 800 is provided on the outer side of the lamp, an elastic sealing ring 300 is installed in the groove 800, and then when the lamp is inserted into the mounting cavity, the elastic sealing ring 300 realizes radial sealing between the lamp and the inner wall of the mounting cavity.

[0083] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limiting, and thus other examples of the exemplary embodiments may have different values.

[0084] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0085] The above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
