[0036] Figure 1A This is a perspective view of a light-emitting module according to an exemplary embodiment of the present invention; Figure 1B yes Figure 1A The light-emitting module shown is a stereoscopic view from another perspective. Figure 1C yes Figure 1A A perspective view of the light-emitting module shown; Figure 2 yes Figure 1A The diagram shown is an exploded view of the light-emitting module.
[0037] like Figures 1A to 2As shown, the light-emitting module 1 mainly includes: a conductive frame 12, which includes a main body 120, the main body 120 including, for example, a plurality of electrically insulated and separate conductive sub-parts; a light source 14 for emitting light, the light source 14 being disposed on the front side of the main body 120 rather than on a circuit board; an auxiliary element 15, the auxiliary element 15 being electrically connected to the light source 14 through the conductive frame 12; and a package 11, the package 11 being disposed around the conductive frame 12 and used to integrally encapsulate the conductive frame 12. The light-emitting module according to this embodiment is characterized in that the package 11 is formed of an injection molding material (e.g., synthetic resin) and is injection molded integrally with the conductive frame 12, thereby watertightly encapsulating the main body 120 of the conductive frame 12. In this way, the light-emitting module 1 can have good waterproof and heat dissipation properties while possessing the desired optical performance, and the manufacturing cost is low.
[0038] Specifically, the package 11 covers the front and back sides of the main body 120, at least a portion of the side of the main body 120 is flush with the package 120 and protrudes from the package 11, the front and back sides of the main body 120 are disposed opposite to each other, and the side of the main body 120 is connected between the front and back sides of the main body 120.

[0039] Depending on the requirements of the actual circuit, auxiliary components 15 may include one or more devices such as driver ICs, capacitors, resistors, etc. Some of these devices will generate heat during use, so auxiliary components 15 are also collectively referred to as heat-generating devices.
[0040] The conductive frame 12 can be a single-layer plate made of a metal (e.g., copper) sheet, which has good conductivity and heat dissipation performance. Multiple circuit pins 122 and support / positioning feet 121a, 121b, 121c, and 121d remaining from the manufacturing process of the conductive frame 12 are arranged around the conductive frame 12. These circuit pins 122 include a power supply pin 122a, a ground pin 122b, a first signal pin 122c, and a second signal pin 122d. Unless there is ambiguity, pins 122a, 122b, 122c, and 122d can be collectively referred to as circuit pins 122. These circuit pins 122 are used for electrical connection to external circuitry to receive power signals and / or control signals from external circuitry. A port 111 is provided at one end of the package 11 to allow the circuit pins 122 to be exposed from the package 11.
[0041] The light source 14 can be a commercially available general-purpose LED. Additionally, such as... Figure 2As shown, the light source 14 can be an LED chip and includes a positive electrode and a negative electrode. One of the positive and negative electrodes is directly soldered to a portion of the conductive frame 12, and the other of the positive and negative electrodes is electrically connected to another portion of the conductive frame 12 via a conductive gold wire 141. Although Figure 2 Although not clearly depicted, it should be understood that the LED chip and conductive gold wire 141 are coated with protective adhesive, which can protect the LED chip and conductive gold wire 141 without affecting the light output performance of the LED chip.
[0042] Figure 6A yes Figure 1A The circuit diagram of the light-emitting module 1 is shown. Figure 2 and Figure 6A As shown, the light source 14 may include RGB LEDs, that is, the light source 14 includes an LED R that emits red light, an LED G that emits green light, and an LED B that emits blue light. In this case, the auxiliary component 15 includes: a driver 151, which is electrically connected to the light source 14 for controlling the light emitted by the light source 14; a filter capacitor C, which is electrically connected between the power supply pin 122a (also referred to as POWER) and the ground pin 122b (also referred to as GND) for filtering out interference signals; and a protection diode D, which is connected in series with the power supply pin 122a for protecting the light source 14. Specifically, power supply pin 122a is electrically connected to the positive terminal of light source 14 and the power supply terminal VS of driver 151, the negative terminal of light source 14 is electrically connected to the output control terminals LC0, LC1, and LC2 of driver, ground pin 122b is electrically connected to the ground terminal GND of driver 151, and the first signal pin 122c (also denoted as LIN_IN) and the second signal pin 122d (also denoted as LIN_OUT) are electrically connected to the first signal terminal LININ and the second signal terminal LINOUT of driver, respectively.
[0043] In addition, such as Figure 2 As shown, a light-emitting aperture 112 is provided in the package 11 at a position opposite to the light source 14. A lens 13 is installed in the light-emitting aperture 112, with at least a portion of the lens 13 disposed within the light-emitting aperture 112. The lens 13 is used to converge and shape the light emitted by the light source 14. Specifically, the main light-emitting direction of the light source 14 is perpendicular to the front surface of the main body 120, the beam angle of the light emitted by the light source 14 is between 110° and 180°, and the beam angle of the light emitted by the lens 13 is between 0° and 100°, thereby making the light more concentrated and ensuring light efficiency.
[0044] Figure 3A yes Figure 1A A three-dimensional view of the lens in the light-emitting module shown; Figure 3B yes Figure 3AThe image shows a cross-sectional view of the lens. (As shown) Figures 2 to 3B As shown, lens 13 includes multiple (in) Figure 3A There are three converging sections 130, each corresponding to one of the RGB LEDs, used to converge the light from the corresponding light source 14. Each converging section 130 includes: an incident surface 131 for receiving light emitted from the light source 14, wherein the distance between the incident surface 131 and the light source 14 is less than 0.5 mm to improve the light collection efficiency of the lens 13; an emitting surface 132 for emitting light received from the incident surface 131; and a guiding section 133 connecting the incident surface 131 and the emitting surface 132. The guiding section 133 is conical and has an optical structure thereon, so that more light received from the incident surface 131 is reflected to the emitting surface 132. This not only ensures light efficiency but also makes the light more uniform.
[0045] The lens 13 also includes a first mounting portion 134 connected to the converging portion 130. Accordingly, as... Figure 2 As shown, a mounting groove 113 is provided on the package 11, and the lens 13 is bonded to the mounting groove 113 via a first mounting portion 134. The mounting groove 113 and the light-emitting aperture 112 are connected in the figure, but in other embodiments, the mounting groove 113 and the light-emitting aperture 112 may not be connected, and they may be spaced apart by a portion of the package. Additionally, the lens 13 also includes a second mounting portion 135 connected to the converging portion 130, and this second mounting portion 135 has a mounting hole 136. The mounting hole 136 is used to mount a light guide (described later).
[0046] The previous text described the case where light source 14 includes RGB LEDs. In reality, light source 14 can also include only monochrome LEDs or dual-color LEDs. Figure 4 This is a perspective view of a lens including only a monochrome LED, wherein lens 13' includes only one converging portion 130'. It is worth noting that for dual-color LEDs or tri-color RGB LEDs, the lens may also include only a single converging portion. In this case, a single converging portion can be used to simultaneously collect and converge the light from all multiple LED light sources, thereby simplifying the structural design of the lens. Figure 6B This is a circuit diagram of a light-emitting module that includes only a monochrome LED, as an exemplary embodiment.
[0047] In this case, the light source 14 may consist only of an LED capable of emitting white light, an LED capable of emitting amber (i.e., yellow) light, or an LED capable of emitting red light. In this case, such as... Figure 6BAs shown, auxiliary component 15 includes: filter capacitors C1, C2, and C3, which are electrically connected between ground pin 122b (also referred to as GND) and other pins, such as first signal pin 122c (also referred to as PTC), second signal pin 122d (also referred to as BIN), and power supply pin 122a (also referred to as POWER), respectively. Filter capacitors C1, C2, and C3 are used to filter out interference signals; a thermistor RT1, which is electrically connected between the first signal pin PTC and the ground pin GND, and is used to detect the temperature of the light source 14; and a category detection resistor R1, which is electrically connected between the second signal pin BIN and the ground pin GND, and is used to detect the category of the light source 14.
[0048] Figure 5A This is a 3D view of the light-emitting module 1 with the light guide 3 installed; Figure 5B yes Figure 5A The cross-sectional view of the light-emitting module 1 is shown. (As shown...) Figure 5A and Figure 5B As shown, the light-emitting module 1 also includes a light guide 3, one end of which is disposed in the mounting hole 136 of the lens 13'. The light guide 3 can be bonded to the mounting hole 136 with optical adhesive or fixed therein by other means, allowing light emitted from the light-emitting surface 132 of the lens 13' to propagate within the light guide 3 and exit from the side of the light guide 3 along its length, thus forming a long strip of light. Optical adhesive is disposed between the light guide 3 and the lens 13', filling the air gap between them, which improves light efficiency.
[0049] Figures 7A to 7D It shows Figure 1A The manufacturing steps of the light-emitting module 1 shown are as follows.
[0050] First, such as Figure 7A As shown, multiple (in) are formed on the blank metal sheet 100 by, for example, a stamping process. Figure 7A The initial outline of the conductive frame 12 is shown in the figure. At this time, the multiple circuit pins 122 of the conductive frame 12 and the support / positioning feet 121a, 121b, 121c, 121d are still connected to the blank metal sheet 100 so as to support and position the initial outline of the conductive frame 12.
[0051] Then, as Figure 7B As shown, the aforementioned light source 14 and auxiliary components 15 (such as one or more of a driver IC, capacitor, and resistor) are mounted onto the respective conductive frames 12. For clarity, Figure 7BThe image only depicts the device mounting on one conductive frame 12 located at the lower left corner of the blank metal sheet 100. It is understood that the device mounting on the other conductive frames is similar to the device mounting on the conductive frame 12.
[0052] Then, as Figure 7C As shown, the encapsulation 11 is formed around the conductive frame 12 using, for example, an injection molding process with injection molding material. For clarity, Figure 7C The image only depicts the formation of the encapsulation 11 on one conductive frame 12 at the lower left corner of the blank metal sheet 100. It is understood that the formation of the encapsulations on the other conductive frames is similar to that on the conductive frame 12.
[0053] Then, as Figure 7D As shown, lens 13 is mounted into light-emitting aperture 112 pre-formed in package 11. Although Figure 7D Although not shown or visible, it is understood that a suitable transparent protective adhesive can be applied between the outer peripheral wall of lens 13 and the inner peripheral wall of the light-emitting aperture 112 in the package 11, and between lens 13 and light source 14, to improve the optical and sealing performance of the component. If an RGB chip is used as the light source, a completely transparent optical adhesive is preferably used; if a white, yellow, or red monochromatic chip is used as the light source, a transparent protective adhesive mixed with other color powders is preferably used. For clarity, Figure 7D The image only depicts the lens 13 mounted in the package 11 on one conductive frame 12 at the lower left corner of the blank metal sheet 100. It is understood that the lens mounting arrangements in the packages on the other conductive frames are similar to those in the packages on the conductive frame 12.

Additionally, for insulation and other considerations, the exposed support / positioning feet 121a, 121b, 121c, and 121d (see [reference]) after cutting can be [removed / removed]. Figure 1A Grinding and / or encapsulation are performed to form a shape such as Figure 8 The light-emitting module 1' shown has non-exposed support / positioning feet 121a, 121b, 121c, and 121d.

Specifically, in the case of manufacturing the light-emitting module 1 including the light guide 3, it is possible to... Figure 7DAfter the steps shown and before forming an independent light-emitting module through the cutting process, one end of the light guide 3 is installed into the mounting hole 136 of the lens 13. Of course, it is also possible to install one end of the light guide 3 into the mounting hole 136 of the lens 13 after forming an independent light-emitting module through the cutting process.

Figure 1A The overall structure of the light-emitting module 1 shown is similar to that of its main components; the main difference between the two is that... Figures 10A to 11 The light-emitting module 2 shown also includes a metal casing 21.
[0058] Specifically, to further enhance the heat dissipation performance of the light-emitting module 2, when the light-emitting module 2 includes heat-generating devices such as the light source 14 and auxiliary components 15, an opening may be provided in the package 11 (see...). Figure 11 The back side of the main body is exposed. An auxiliary element 15 is disposed on the back side of the main body via a circuit board 16, with the back side and front side of the main body facing each other. Simultaneously, a metal housing 21 is mounted in thermal contact with the auxiliary element 15 and the circuit board 16, so that heat dissipated by the auxiliary element 15 and heat emitted by the light source 14 are conducted to the metal housing 21. The material forming the metal housing 21 can be aluminum or an aluminum alloy or other suitable metal material, which has good heat dissipation properties. Although Figures 10A to 11 Although not shown or visible, it is understood that thermally conductive adhesive may be filled between the metal casing 21 and the heat dissipation surfaces of the auxiliary components 15 and the circuit board 16 it abuts against, in order to further improve the thermal conductivity between them.
[0059] A recess 211 is provided on the metal casing 21 to make the metal casing 21 more accurately positioned relative to the package 11, and to further increase the rigidity and surface area of the metal casing 21, that is, to correspondingly increase the heat dissipation area and further improve the heat dissipation effect.
[0060] Additionally, snap-fit structures can be provided on the package 11 and the metal casing 21 to allow the metal casing 21 to be securely and accurately snapped onto the package 11. Specifically, as shown... Figure 11As shown, the snap-fit structure consists of a protrusion 113 formed on the package 11 and a corresponding recess 213 formed on the metal housing 21. Specifically, the protrusion 113 and the recess 213 snap together. Furthermore, a protrusion 114 is formed on the package 11, and a recess 212 is formed on the metal housing 21; the protrusion 114 and the recess 212 serve a limiting / positioning function. In some embodiments, thermally conductive adhesive or thermally conductive grease may be provided between the package 11 and the metal housing 21, which can further improve heat dissipation performance. Additionally, the package 11 and the metal housing 21 can also be fixed to each other by a threaded connection, or the package 11 and the metal housing 21 can be directly bonded together by thermally conductive adhesive without any other fixing structure.
