[0021] Reference Figure 1-3 As shown, a biological lighting light source of the present embodiment includes a PCB board 5 and a first heat-conducting substrate 3, wherein the PCB board 5 is detachably connected to the first heat-conducting substrate 3, a plurality of first contacts 31 are arranged on the first heat-conducting substrate 3, a plurality of second contacts 51 are arranged on the PCB board 5, a plurality of first contacts 31 and a plurality of second contacts 51 are in one-to-one correspondence and electrically connected, a plurality of input contacts 52 are arranged on the PCB board 5, a plurality of input contacts 52 and a plurality of second contacts 51 are electrically connected, a plurality of mounting points 34 are arranged on the first heat-conducting substrate 3, a plurality of mounting points 34 and the first contacts 31 are electrically connected, and two adjacent mounting points 34 are detachably connected to a lamp bead assembly 6;

[0022] The lamp bead assembly 6 includes an LED chip 65, a second heat-conducting substrate 62 and two electrodes 63, and the LED chip 65, the second heat-conducting substrate 62 and the two electrodes 63 are arranged in sequence from top to bottom, the LED chip 65 is electrically connected to the second heat-conducting substrate 62, and the two electrodes 63 can be electrically connected to two adjacent mounting points 34 respectively. The present invention unifies the specifications of LED chips 65 of different specifications and then packages them, so as to solve the problem that it is difficult to unify the packaging of chips from different manufacturers, and changes the cumbersome production process of solid crystal, welding wire and spraying phosphor into a simple SMT packaging production process, so that the color of the light source can be freely combined very conveniently; and compared with the traditional unified packaging, the lamp bead maintenance cost is also greatly reduced, and only the damaged lamp bead assembly 6 needs to be disassembled and replaced. This structure brings a large space for the wiring of the light source, and when each group of chips emits light, more light is in the middle of the lens 1, so that the focused light spot is relatively symmetrical from the center, so that when the light source is made into a secondary optical structure, the symmetry of the optical axis is well improved, so that the light efficiency of the multi-color integrated light source is far better than that of the traditional packaging structure.

[0023] In one embodiment, the PCB board 5 is provided with an empty slot which penetrates the PCB board 5, and the cross-section of the empty slot is the same as the cross-section area of ​​the first thermally conductive substrate 3, and the first thermally conductive substrate 3 can be directly placed in the empty slot. The advantage of this connection method is that the PCB board 5 and the first thermally conductive substrate 3 can be in the same plane, which facilitates the connection between the first contact 31 and the second contact 51.

[0024] In one embodiment, at least one wiring layer is provided on the PCB board 5. For the first thermal conductive substrate 3 with a large number of lamp beads, it is more convenient to electrically connect the first thermal conductive substrate 3. At the same time, the setting of the multi-layer PCB board 5 can further reduce the volume of the PCB board 5.

[0025] In one embodiment, a plurality of the first contacts 31 and a plurality of the second contacts 51 are electrically connected by direct welding, which not only enables electricity to flow between the first contacts 31 and the second contacts 51 , but also enables direct fixed connection between the first thermal conductive substrate 3 and the PCB board 5 .

[0026] In one embodiment, the materials of the first heat-conducting substrate 3 and the second heat-conducting substrate 62 include, but are not limited to, copper and aluminum, which can conveniently dissipate the high heat generated by the lamp beads.

[0027] In one embodiment, the lamp bead assembly 6 is packaged onto the first heat-conducting substrate 3 according to a desired arrangement by an SMT placement machine.

[0028] Reference Figure 2As shown, the lighting light source also includes a heat-conducting substrate fixing frame 4, a lens fixing frame 2, and a lens 1. The lens 1 is detachably connected to the lens fixing frame 2, and the lens fixing frame 2, the first heat-conducting substrate 3, and the heat-conducting substrate fixing frame 4 are detachably connected in sequence. The detachable connection arrangement makes it easier to install each component, and the maintenance cost is lower than that of the one-piece molding method. In addition, in the breeding environment of different marine organisms, lenses 1 of different sizes are required for focusing. The detachable connection makes it more convenient to replace the lens 1. When the lens fixing frame 2, the first heat-conducting substrate 3, and the heat-conducting substrate fixing frame 4 are fixed, a clamping space is formed between the lens fixing frame 2 and the heat-conducting substrate fixing frame 4 to provide a clamping force acting on the PCB board 5 installed on the first heat-conducting substrate 3.

[0029] Reference Figure 1 As shown, the first heat-conducting substrate 3 and the lens fixing frame 2 are both provided with mounting holes 32 corresponding to each other in position, and the mounting holes 32 are detachably connected with bolts.

[0030] Reference Figure 3 As shown, the LED chip 65 is provided with a reflective material 61 on its periphery. The reflective material 61 has a very high reflectivity and can reflect the light source irradiated around the LED chip 65, so that the LED chip 65 emits direct light, thereby improving the utilization rate of light.

[0031] In one embodiment, the reflective material 61 includes but is not limited to metal reflective film, micro-prismatic reflective film, etc.

[0032] Reference Figure 1 As shown, the outer sides of the LED chip 65 and the second heat-conducting substrate 62 are covered with a protective resin 64, and the protective resin 64 includes but is not limited to materials such as cycloolefin polymers, and has the advantages of high transparency, low birefringence, low water absorption, high rigidity, high heat resistance, and good water vapor airtightness. In the process of breeding marine organisms, the environment is high temperature and high humidity. A large amount of water vapor evaporates and it is very easy for water vapor to enter the lamp, causing a large number of electronic components to oxidize and even cause the risk of leakage. The protective resin 64 can effectively prevent water vapor from entering the lamp without affecting normal lighting, and can also have a good protective effect on some splashing water droplets.

[0033] Reference Figure 1 As shown, the LED chip 65 is electrically connected to the second thermally conductive substrate 62 via a gold wire.

[0034] Reference Figure 1 As shown, the LED chip 65 and the second thermally conductive substrate 62 are fixed by silver paste or epoxy resin.

[0035] In one embodiment, a plurality of conductive vias are vertically disposed through the second heat-conducting substrate 62 , and the LED chip 65 is conveniently electrically connected to the electrode 63 through the conductive vias.

[0036] Reference Figure 1 As shown, a temperature sensor 33 is provided on the first heat-conducting substrate 3, and the temperature sensor 33 is electrically connected to any two adjacent mounting points 34. A CPU is provided on the PCB board 5, and the temperature sensor 33 is electrically connected to the PCB board 5. The temperature sensor 33 obtains the temperature data of the light source and sends the data to the CPU of the PCB board 5. If the temperature of the light source is too high, the light source will be automatically turned off, thereby preventing the light source from being damaged due to excessive temperature.

[0037] Working principle: When it is necessary to install a light source, first select the packaged LED chip 65 according to the required marine organisms to be cultivated, then place it in the installation point 34 and package it, then place the packaged first thermally conductive substrate 3 in the corresponding PCB board 5, so that the first contact 31 and the second contact 51 are aligned one by one and welded, then place the lens 1 in the lens fixing frame 2, and then place the PCB board 5 between the lens fixing frame 2 and the thermally conductive substrate fixing frame 4 for clamping. At this time, the first thermally conductive substrate 3 is in the thermally conductive substrate fixing frame 4, and then screw bolts into the mounting holes 32 on the first thermally conductive substrate 3 and the lens fixing frame 2 to fix them.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
