[0034] Please refer to Figures 1 to 5 , the embodiments of the present invention provide a blowing and dust removal and dust-proof strip light source with light attenuation monitoring, including: main body 1, light source circuit board 2, arc diffuser 3, light attenuation detection module 4 and blowing and dust removal module 5;

[0035] As Figures 1 to 3As shown in the figure, a first installation groove 11 and two second installation cavities 12 respectively communicating with the left and right ends of the first installation groove 11 are provided on the main body 1. A plurality of first installation holes 13 are provided on the first installation groove 11. The light source circuit board 2 is installed in the first installation groove 11 by screws. A dust-proof member 6 is installed on the second installation cavity 12. The dust-proof member 6 can completely seal the two end parts of the first installation groove 11, so as to avoid dust entering the first installation groove 11. In particular, the dust-proof member 6 in this embodiment is a sponge pad, which has good elasticity and dust-proof function, and can effectively and comprehensively fill the second installation cavity 12 and seal the two end parts of the first installation groove 11;

[0036] The arc diffuser plate 3 is snap-connected to the main body 1 and is placed above the light source circuit board 2. The arc diffuser plate 3 in this embodiment is made of anti-static transparent acrylic plate. In some preferred embodiments, the arc diffuser plate 3 can also be an anti-static transparent PVC plate (anti-static polyvinyl chloride plate), an anti-static transparent PC plate (anti-static polycarbonate plate), an anti-static transparent PET plate (diethyl terephthalate) or other anti-static transparent materials. The light-emitting surface of the arc diffuser plate 3 is provided with a fine line surface structure or a frosted structure to improve the uniformity of light emission;

[0037] As Figure 3 shown, the arc diffuser plate 3 is of an overall arc structure. The two end parts of the arc diffuser plate 3 horizontally extend to form snap-fit edges 31. As Figure 3 to and Figure 5 shown, a first card slot 14 is provided on the main body 1. The first card slot 14 is arranged above the first installation groove 11. The snap-fit edge 31 is inserted into the first card slot 14, so that the arc diffuser plate 3 can completely wrap the light source circuit board 2, and the light emitted by the light source circuit board 2 can only be emitted from the arc diffuser plate 3. In addition, after the snap-fit edge 31 is inserted into the first card slot 14, sealant is poured into the first card slot 14, so as to form a sealing layer 32 between the snap-fit edge 31 and the inner wall of the first card slot 14 of the main body 1. The inner walls of the two ends of the arc diffuser plate 3 are respectively abutted against the dust-proof member 6. As Figure 6 shown, the above-mentioned dust-proof member 6 is provided with an installation part 61 matching the second installation cavity 12. The upper end of the dust-proof member 6 is an arc-shaped abutting part 62 matching the arc diffuser plate 3.

[0038] In order to further fix the light source circuit board 2 and the arc diffuser plate 3, in this embodiment, two end plates 15 are further included. The two end plates 15 are respectively fixedly connected to the left and right ends of the main board by screws, so that the two end plates 15 can cooperate to clamp and fix the light source circuit board 2 and the arc diffuser plate 3; in this embodiment, a silica gel pad 7 is also provided. The silica gel pad 7 is integrally in a "U" shape and is arranged around the dust-proof member 6 and fixed between the main body 1 and the end plate 15, so as to improve the poor sealing of the connection between the main body 1 and the end plate 15 and improve the overall dust-proof and waterproof effect.

[0039] The light decay detection module 4 installed on the flank of the main body 1, and a detection hole 16 matching the light decay detection module 4 is opened on the main body 1;

[0040] As Figure 7 shown, the light decay detection module 4 includes an installation housing 41 and a PCB main board 42 arranged in the installation housing 41. A photosensitive element 43 is provided on the PCB main board 42. The photosensitive element 43 extends outside the installation housing 41 and is placed on the detection hole 16. Preferably, the photosensitive element 43 in this embodiment uses a photosensitive sensor to detect the light source in the main body 1. An MCU (single-chip microcomputer) is integrated on the PCB main board 42 to process the signals of the photosensitive element 43. In this embodiment, two LED indicators 44 are integrated on the PCB main board 42. One of them is a green LED indicator 44 when lit, and the other is a red LED indicator 44 when lit. An observation window 45 matching the position of the LED indicator 44 is provided on the installation housing 41. A transparent window plate 46 is provided on the observation window 45. A Type-C interface 47 is integrated on the PCB main board 42, and a second opening 411 for passing through the Type-C interface 47 is provided on the installation housing 41.

[0041] As Figure 2 shown, the air blowing dust removal module 5 provided on one side of the main body 1, the air blowing dust removal module 5 includes a fixing member 51 provided on one side of the main body 1 and a rotatable universal blowing nozzle 52 fixedly connected to the fixing member 51. The universal blowing nozzle 52 is connected with an air pipe 53.

[0042] Figure 1 And Figure 2 shown, on the other side of the main body 1 far from the air blowing dust removal module 5, there is an external plug 8 connected to the light source circuit board 2, which is powered by an external power supply. Of course, in order to prevent dust from entering, a cable joint 81 is provided between the external plug 8 and the main body 1 for connection.

[0043] Brief description of the working principle of the present utility model: When in use, first connect the power supply through the external plug 8, and then connect the air pipe 53 to an external air source to supply air to the universal nozzle 52. When in use, the light source on the light source circuit board 2 is dimmed through the arc diffuser 3 and can be evenly emitted to cooperate with the vision system for detection. The arc diffuser 3 of the present utility model completely wraps the light source circuit board 2, and a sealing layer 32 is formed by pouring sealant at the clamping connection between the arc diffuser 3 and the main body 1, which plays a good role in waterproofing and dustproofing. Moreover, the arc diffuser 3 is made of an anti-static transparent material, so that dust with impurities is not easily adhered to the surface of the arc diffuser 3 due to static electricity. Then, cooperate with the universal nozzle 52 to blow away the particles, dust, etc. attached to the surface of the main body 1 and the arc diffuser 3. Of course, the air blowing and dust removing module 5 can also be connected to an intelligent air source system, and the air source system can set a program to make the air blowing and dust removing module 5 blow air regularly, which can also achieve the effect of dust removal; The setting of the light decay detection module 4 is to monitor the attenuation problem of the light source in real time. The photosensitive element 43 in the light decay detection module 4 can receive the light emission intensity signal of the light. When the light emission intensity signal changes, that is, when the light source brightness decays, the PCB main board 42 in the light decay detection module 4 can convert the change difference value of the light emission intensity signal into an electrical signal and calculate its change difference value. The PCB main board 42 can identify the change difference value of the electrical signal to judge the brightness attenuation degree of the light source. The brightness value of the light source converted and recognized can be set in advance through the PCB main board 42. When it is above the set brightness value, the green LED indicator 44 is on and the red LED indicator 44 is off; when it is below the set brightness value, it is the opposite. In this way, the operator can monitor the brightness attenuation degree according to the LED indicator 44 for detection, repair or replacement of the light source; Of course, the PCB main board 42 can also be connected to the PC control terminal through the Type-C interface 47, and the brightness threshold is set by the control terminal. When the light source brightness drops below the threshold, the red LED indicator 44 lights up.

[0044] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
