Description

Technical Field

[0001] This utility model relates to the field of lighting device technology, and in particular to an LED cold light source black light that can replace the fluorescent tubes in the cleaning station. Background Technology

[0002] High-pressure mercury lamps are light sources that are excited by heat energy. 80-90% of their energy is converted into heat energy, and about 10% is converted into light energy. The process of converting electrical energy into heat energy and then heat energy into light energy results in high heat loss and low luminous efficiency. Moreover, their lifespan is short, only 2000-3000 hours, and they need to be replaced frequently. When applied to manual rinsing processes (where water vapor is generated during manual rinsing of workpieces, such as manual rinsing at the cleaning station), the mercury lamp is suspended above the fluorescent penetrating cleaning station, more than 1 meter away from the inspection station. If the mercury lamp is damaged, the operator needs to climb a ladder to disassemble it, which is very inconvenient. Furthermore, the weak light emitted by the mercury lamp means that it cannot reach the maximum illuminance when it is first turned on, and it takes 3-5 minutes to reach the maximum value. Moreover, its wavelength is dispersed, concentrated in the 315-400nm range, which can easily cause missed detections. In addition, high-pressure mercury lamps do not have color filters and cannot filter out the harmful UV-B and UV-C radiation emitted by the lamp, which is harmful to the human body. Therefore, a filter must be provided to protect the inspection personnel.

[0003] In the prior art, such as the LED module black light with application number 201922179001.8, the principle of making fluorescent materials glow by ultraviolet light can be used to reveal defects on the surface of parts. However, if large-area illumination is required, multiple LED module black lights need to be integrated to facilitate assembly and application. Utility Model Content

[0004] The purpose of this utility model is to provide an LED cold light source black light that can replace the fluorescent tubes in the cleaning station. Multiple black light modules are fixed inside the lamp cover by the cooperation of the base plate assembly and the positioning plate. Multiple black light modules are fixed simultaneously by abutting only, and the fixing structure is simple. Moreover, the overall structure is a flat plate structure, which is simple and compact, easy to use and has a long service life, and can reduce the labor intensity of workers.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: an LED cold light source black light that replaces the fluorescent tubes in the cleaning station, comprising a lampshade, black light modules, and a base plate assembly. The lampshade is provided with a constant current drive and a positioning plate. The positioning plate is provided with multiple positioning holes, and multiple black light modules are respectively disposed in the multiple positioning holes and electrically connected to the constant current drive. The base plate assembly is disposed on the lampshade and abuts against the lower end of the black light modules. The base plate assembly has a transmission area at least in the light-emitting area of ​​the black light modules.

[0007] As a further optimization, the substrate is embedded in the positioning hole, and the positioning sleeve abuts against the base plate assembly.

[0008] As a further optimization, the horizontal cross-section of the substrate and the positioning hole is an oblong structure, which can prevent the black light module from rotating relative to the positioning plate.

[0009] As a further optimization, the lampshade includes a cover body and side plates, with a pair of side plates respectively locked to opposite ends of the cover body and both abutting against the side walls of the positioning plate and base plate assembly.

[0010] As a further optimization, the cover includes a main frame with an upper end and a pair of support plates disposed at the lower end of the main frame and spaced apart from each other. A positioning platform is formed between the support plates and the main frame. The lower end of the bottom plate assembly abuts against the support plate, and the side wall abuts against the positioning platform.

[0011] As a further optimization, the side plate has a cavity, and a fan is installed on the side plate within the cavity to help dissipate heat quickly.

[0012] As a further optimization, the base plate assembly includes a light-transmitting plate and a glass plate. The light-transmitting plate has multiple light-transmitting holes. The glass plate abuts against the support plate. The light-transmitting plate abuts against the glass plate. The black light module abuts against the light-transmitting plate, and its light path is arranged opposite to the light-transmitting holes.

[0025] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0026] like Figures 1 to 3As shown, an LED cold light source black light that replaces fluorescent tubes in cleaning stations includes a lampshade 10, a black light module 30, and a base plate assembly 40. The lampshade 10 is provided with a constant current driver 100 and a positioning plate 20. The positioning plate 20 is provided with multiple positioning holes 21. For example, eighteen positioning holes 21 are arranged in two rows side by side. Multiple black light modules 30 are respectively arranged in multiple positioning holes 21, that is, eighteen black light modules 30 are respectively arranged in eighteen positioning holes 21, and each black light module 30 is electrically connected to the constant current driver 100. The base plate assembly 40 is arranged on the lampshade 10 and abuts against the lower end of the black light module 30. The base plate assembly 40 has a transmission area at least in the light-emitting area of ​​the black light module 30.

[0027] In this invention, the positioning plate 20 can be screwed onto the lamp cover 10, and the black light module 30 is positioned in the positioning holes 21 on the positioning plate 20, which ensures the accurate positioning of the black light module 30. The black light module 30 is then fixed by the bottom plate assembly 40 mounted on the lamp cover 10 abutting against the lower end of the black light module 30, thus fixing the black light module 30 inside the lamp cover 10. The black light module 30 is electrically connected to the constant current drive 100 to emit light. The constant current drive output ensures that the luminous intensity of the black light module 30 is more stable, and the light from the black light module 30 is stably irradiated through the transmission area on the bottom plate assembly 40.

[0028] This utility model fixes the black light module 30 inside the lamp cover 10 through the cooperation of the base plate assembly 40 and the positioning plate 20. The overall structure is a flat plate structure, which is compact, has a long service life, and does not require frequent replacement of black light, thus reducing the labor intensity of workers. Moreover, the upper end of the black light module 30 is positioned through the positioning hole 21 and the lower end of the black light module 30 is abutted by the base plate assembly 40. The fixing structure is simple and convenient for the installation and replacement of the black light module 30.

[0029] Preferred, such as Figure 4As shown, the black light module 30 includes a substrate 31, a positioning sleeve 32, and an LED black light assembly 33. The positioning sleeve 32 is locked to the substrate 31 by screws passing through locking holes 321 on both sides. The substrate 31 is embedded in the positioning hole 21. The LED black light assembly 33 is disposed in the positioning sleeve 32, and the positioning sleeve 32 abuts against the base plate assembly 40 for fixation. The specific structure of the black light module 30 can be found in an LED module-type black light application with application number 201922179001.8. Based on the prior art, preferably, the LED black light assembly 33 includes an LED cold light source black light, a circuit assembly, and a plug assembly. The LED cold light source black light is connected to the plug assembly 34 through the circuit assembly, and the plug assembly 34 is then electrically connected to the constant source driver 100. The light-emitting principle of LED black lights is based on semiconductor light-emitting technology. Using LEDs (light-emitting diodes) as the light source, a forward voltage is applied to the light-emitting semiconductor, causing holes injected from the P-region to the N-region and electrons injected from the N-region to the P-region to recombine with electrons and holes in the N-region and P-region respectively within a few micrometers of the PN structure, generating spontaneously emitted ultraviolet light. This light-emitting principle allows LED black lights to emit ultraviolet light of specific wavelengths, which are strongly attracted to certain insects. Therefore, LED black lights are widely used in agriculture, pest control, and other fields. In contrast, traditional thermal black lights generate a glow discharge through the activation electrodes, causing mercury to evaporate and ionize, creating an arc between the two main electrodes to emit ultraviolet light. The spectrum emitted by such lights is continuous, while the spectrum emitted by LED black lights is purer, based on photons of specific wavelengths generated by direct bandgap transitions in semiconductor materials. This light-emitting method makes LED black lights more efficient and have a longer lifespan in specific applications. The light-emitting principle of cold light source lamps is based on the phenomenon where electron collisions under the influence of an electric field excite fluorescent materials to produce light emission. This results in excellent optical and flicker-free characteristics. Cold light sources do not generate heat during operation, avoiding a series of problems related to heat accumulation. Cold light source lamps convert almost all other energy into visible light, with very little light of other wavelengths. Therefore, LED cold light source black lights have a lifespan of up to 30,000 hours, exhibiting good durability and stability. The intensity of LED cold light source black lights is higher than that of traditional hot light source ultraviolet lamps, with a higher photoelectric conversion efficiency, converting over 60% of electrical energy into light energy. Traditional hot light source ultraviolet lamps only have a light energy utilization rate of 10%, making LED cold light source black lights more energy-efficient than traditional ultraviolet lamps. Therefore, LED cold light source black lights have a long lifespan, concentrated wavelength, and high intensity, solving the problems of frequent maintenance and low intensity associated with mercury lamps. Figure 6 and Figure 7As shown, compared to traditional conventional thermal light sources, LED cold light source black lights have wavelengths concentrated in the 360-370nm range, with a concentrated spectrum and a center wavelength of 365nm. This reduces the likelihood of missed detections, solves the problem of frequent maintenance of mercury lamps, and also reduces power consumption, making them more energy-efficient. Traditional thermal light sources emit blue-violet light at a vertical angle, which cannot cover the edge area of ​​the workpiece. The light emitted by this application can be at an angle, emitting blue light and illuminating a wider area of ​​the workpiece edge. When illuminating at the same height, the light emitted by thermal light sources is weak and cannot fully cover the surface of the detection area. The light emitted by this application is strong and can fully cover the surface of the detection area.

[0030] Preferably, the horizontal cross-section of the substrate 31 and the positioning hole 21 is a waist-shaped structure. The non-circular structure allows the substrate 31 to be embedded in the positioning hole 21 in a specific state without rotation.

[0031] like Figure 1 and Figure 2 As shown, the lampshade 10 includes a cover body 11 and side plates 12. A pair of side plates 12 are respectively locked to opposite ends of the cover body 11, and both abut against the side walls of the positioning plate 20 and the base plate assembly 40. During assembly, the positioning plate 20 is first locked onto the cover body 11. After the whole assembly is inverted, the base plate 31 of the black light module 30 is inserted into the positioning holes 21, and then the base plate assembly 40 is inserted to abut against the positioning sleeve 30. Locking the pair of side plates 12 at both ends completes the assembly and fixes the black light module 30 and the base plate assembly 40.

[0032] Preferably, the cover 12 includes a main frame 111 with a sealed upper part and a pair of support plates 112 disposed at the lower end of the main frame 111 and spaced apart from each other. A positioning platform 113 is formed between the support plate 112 and the main frame 111. The lower end of the bottom plate assembly 40 abuts against the support plate 112, and the side wall abuts against the positioning platform 113. Therefore, in the longitudinal direction, the mutual abutment between the support plate 112, the black light module 30 and the positioning plate 20 can realize the fixation of the black light module 30 and the bottom plate assembly 40, ensuring the installation stability of the two in the overall structure. The positioning platform 113 can ensure the stability of the bottom plate assembly 40 in the lateral direction. The side wall of the positioning platform 113 is provided with a locking hole 1110, which can be used to lock the side plate 12 onto the main frame 111 after the screw is inserted.

[0033] like Figure 5 As shown, the side plate 12 has a cavity 120, and a fan 121 is provided on the side plate 12 inside the cavity 120. The operation of the fan 121 can improve the overall heat dissipation performance.

[0034] For example Figure 1As shown, the base plate assembly 40 includes a light-transmitting plate 41 and a glass plate 42. The light-transmitting plate 41 is provided with a plurality of light-transmitting holes 411. The glass plate 42 abuts against the support plate 112. The light-transmitting plate 41 abuts against the glass plate 42. The black light module 30 (positioning sleeve 32) abuts against the light-transmitting plate 41, and its light path is arranged opposite to the light-transmitting holes 411. The light from the black light module 30 passes through the light-transmitting holes 411 and then penetrates the glass plate 42 to irradiate.

[0035] Furthermore, the base plate assembly 40 also includes a pressure strip 43. The pressure strip 43 is provided at the connection between the lamp cover 11 (carrying plate 112) and the base plate assembly 40, which can improve the overall sealing performance.

[0036] In addition, the upper end of the lampshade 11 is provided with a hanging ring 110, which makes it convenient to hang the LED cold light source black light that replaces the fluorescent tube of the cleaning station above the station.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
