Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of UV glue curing, in particular to a light source device for UV glue curing in deep holes. BACKGROUND

[0002] The ultraviolet light curing glue is also called photosensitive glue, shadowless glue and UV glue, which is a kind of adhesive that must be cured by ultraviolet light. The UV glue curing principle is that the photo initiator or photosensitizer in the UV curing material absorbs ultraviolet light to produce active free radicals or cations under the irradiation of ultraviolet light, which initiates the monomer polymerization and crosslinking chemical reaction, so that the adhesive is converted from liquid to solid within a few seconds. The middle pressure mercury lamp and the light emitting diode emit ultraviolet light and generate a large amount of heat at the same time. Due to the limitation of the heat sink, the existing UV curing light source is generally a planar light source, a linear light source or a point light source.

[0003] The Chinese patent CN102989644A discloses a UV curing method for packaging glue. The technical point is to irradiate the packaging glue with a UV curing lamp, and to adjust the UV curing lamp power, irradiation time and other ways to provide the sealing quality. As can be seen, in the existing UV curing lamp processing, there is no curing lamp for UV glue in deep holes. When the UV glue is applied to the groove on the side wall of the deep hole, the hole wall will block a part of the light, so that the light intensity on the glue is greatly weakened, the curing time of the glue is prolonged, and the quality after curing is poor. Of course, a point light source can be used to irradiate into the deep hole, but the mechanical structure and motion algorithm of this scheme are relatively complex. Although it is called a point light source, it still has a relatively large heat sink in order to dissipate heat. If a narrow hole is encountered, the point light source may not be able to enter. The power of the point light source is generally low, and the curing time of the glue is also prolonged. SUMMARY

[0004] Therefore, the present application provides a light source device for UV glue curing in deep holes to overcome the problems of long curing time and poor curing quality of UV glue in deep holes in the prior art.

[0014] if the real-time hole depth coefficient is within the standard hole depth coefficient range, the central control module does not adjust the initial inclination angle of the lamp plate in each of the lamp plate assemblies;

[0015] If the real-time hole depth coefficient is less than the standard hole depth coefficient range, the central control module will determine the real-time hole depth distance of the deep hole where the UV glue to be cured is located to determine the adjustment of the initial inclination angle of the lamp panel in each lamp panel assembly;

[0016] If the real-time hole depth coefficient is greater than the standard hole depth coefficient range, the central control module will determine the real-time hole depth coefficient according to the maximum hole depth coefficient to determine the adjustment of the initial inclination angle of the lamp panel in each lamp panel assembly;

[0017] Wherein, As=Lh / Ld, As is the real-time hole depth coefficient, Lh is the real-time hole depth distance, and Ld is the real-time hole diameter.

[0018] Further, the central control module is provided with a maximum hole depth coefficient and a minimum inclination angle of the lamp panel. When the central control module determines that the real-time hole depth coefficient is greater than the standard hole depth coefficient range, the central control module compares the real-time hole depth coefficient with the maximum hole depth coefficient,

[0019] If the real-time hole depth coefficient is greater than or equal to the maximum hole depth coefficient, the central control module controls the telescopic rod to retract, so that the initial inclination angle of the lamp panel is reduced to the minimum inclination angle;

[0020] If the real-time hole depth coefficient is less than the maximum hole depth coefficient, the central control module will calculate a first modified inclination angle according to the real-time hole depth coefficient and the standard hole depth coefficient range, and control the telescopic rod to retract, so that the initial inclination angle of the lamp panel is reduced to the first modified inclination angle;

[0021] Wherein, Cx=Ce×[1-(As-Ap) / Ap], Ap=(Am+An) / 2, Cx is the first modified inclination angle, Ce is the initial inclination angle, As is the real-time hole depth coefficient, Am is the maximum value of the standard hole depth coefficient range, An is the minimum value of the standard hole depth coefficient range, and Ap is the intermediate value of the standard hole depth coefficient range.

[0022] Further, the central control module is provided with a standard glue point area. When the lamp panel is irradiated to cure the UV glue in the deep hole at the minimum inclination angle or the first modified inclination angle, the central control module will acquire the image glue point area of the UV glue in the real-time operation image, and determine the image glue point area according to the standard glue point area,

[0023] If the image glue point area is less than or equal to the standard glue point area, the central control module does not control the lamp panel to swing adjustment;

[0024] If the image glue point area is greater than the standard glue point area, the central control module will calculate a swing inclination angle according to the image glue point area and the standard glue point area, and control the lamp panel to swing adjustment by adjusting the retraction and extension of the telescopic rod.

[0025] Further, the central control module controls the telescopic rod to contract when the swing upper limit angle is reached and controls the telescopic rod to extend when the swing lower limit angle is reached according to the swing tilt angle.

[0026] wherein Cr=Cq×[(St-Sb) / St], C1=Cq-Cr, C2=Cq+Cr, Cr is the swing tilt angle, Cq is the current tilt angle of the lamp panel, the current tilt angle of the lamp panel is equal to the minimum tilt angle or the first corrected tilt angle, C1 is the swing upper limit angle, C2 is the swing lower limit angle, St is the image gel point area, and Sb is the standard gel point area.

[0027] Further, the central control module is provided with a standard hole depth distance and a maximum tilt angle of the lamp panel, and the central control module determines the real-time hole depth distance according to the standard hole depth distance when the real-time hole depth coefficient is less than the standard hole depth coefficient range,

[0028] If the real-time hole depth distance is less than or equal to the standard hole depth distance, the central control module controls the telescopic rod to extend, so that the initial tilt angle of the lamp panel increases to the maximum tilt angle.

[0029] If the real-time hole depth distance is greater than the standard hole depth distance, the central control module calculates a second corrected tilt angle according to the real-time hole depth coefficient and the standard hole depth coefficient range, and controls the telescopic rod to extend, so that the initial tilt angle of the lamp panel increases to the second corrected tilt angle.

[0030] wherein Cv=Ce×[1+(Ap-As) / Ap], Ap=(Am+An) / 2, Cv is the second corrected tilt angle, Ce is the initial tilt angle, As is the real-time hole depth coefficient, Am is the maximum value of the standard hole depth coefficient range, An is the minimum value of the standard hole depth coefficient range, and Ap is the intermediate value of the standard hole depth coefficient range.

[0031] Further, the central control module is provided with a standard gray scale change rate, and when the lamp panel irradiates the UV glue in the deep hole, the central control module performs gray scale processing on the obtained real-time operation image, obtains the real-time gel point gray scale of the UV glue in the image to calculate the real-time gray scale change rate, and determines the real-time gray scale change rate according to the standard gray scale change rate,

[0032] If the real-time gray scale change rate is less than the standard gray scale change rate, the central control module adjusts the light source output power of the lamp panel.

[0033] If the real-time gray scale change rate is greater than or equal to the standard gray scale change rate, the central control module does not adjust the light source output power of the lamp panel.

[0034] Where Vs = (G2 - G1) / t, Vs is the real-time grayscale change rate, t is the unit detection time set in the central control module, G2 is the real-time grayscale of the UV glue dots in the current real-time operation image, and G1 is the real-time grayscale of the UV glue dots in the real-time operation image before the unit detection time t; Pg' = Pg × (Vs / Vb), Pg is the light source output power before adjustment, Pg' is the light source output power after adjustment, and Vb is the standard grayscale change rate.

[0035] Furthermore, the central control module is also equipped with power matching parameters. After adjusting the light source output power of the lamp board, the central control module adjusts the heat dissipation output power of the cooling fan according to the adjusted light source output power and the power matching parameters.

[0036] Where Pf = Q × Pg', Pf is the heat dissipation output power after matching adjustment, Pg' is the light source output power after adjustment, and Q is the power matching parameter.

[0037] Furthermore, the central control module is equipped with a first preset temperature and a second preset temperature. The temperature sensing element can detect the real-time temperature of the radiator, and the central control module compares the real-time temperature with the first preset temperature and the second preset temperature.

[0038] If the real-time temperature of the radiator is lower than the first preset temperature, the central control module will adjust the power matching parameter to the first power matching parameter;

[0039] If the real-time temperature of the radiator is greater than or equal to the first preset temperature and less than or equal to the second preset temperature, the central control module will not adjust the power matching parameters;

[0040] If the real-time temperature of the radiator is greater than the second preset temperature, the central control module will adjust the power matching parameter to the second power matching parameter;

[0041] Where Q1=Q-[Q×(T1-Ts) / T1], Q2=Q+[Q×(Ts-T2) / Ts], Q is the power matching parameter, Q1 is the adjusted first power matching parameter, Q2 is the adjusted second power matching parameter, T1 is the first preset temperature, T2 is the second preset temperature, and Ts is the real-time temperature of the radiator.

[0042] Furthermore, the light panel is rectangular, and one side of the light panel is connected to one side of the rectangular cutout on the top plate by a hinge. The light panel can rotate relative to the top plate about the hinge as an axis to adjust the tilt angle. The tilt angle of the light panel is the angle between the light panel and the horizontal direction.

[0043] Compared with the prior art, the beneficial effects of the present application are that by providing a top plate with several rectangular hollows, multiple lamp panel assemblies can be loaded at the same time to realize concentrated irradiation curing operation of multiple light sources, and each lamp panel is independently arranged and has a radiator to ensure stable operation of the lamp panel, the power matching between the cooling fan and each lamp panel is controlled to avoid high temperature in the shell due to too many lamp panels, the irradiation angle of the light source is adjusted in real time by rotating the lamp panel driven by the telescopic rod, and the irradiation angle of each lamp panel is further accurately controlled according to the calculation of the real-time hole depth coefficient by the central control module, thereby improving the curing efficiency of the UV glue in the deep hole and uniformly irradiating the UV glue to make the photosensitizer in the UV glue uniformly absorb photons and ensure the curing quality of the UV glue.

[0044] Especially, the state of the UV glue deep hole to be cured is determined by calculating the real-time hole depth coefficient of the UV glue to be cured in the deep hole, and it is determined whether to adjust the initial inclination angle of each lamp panel, when the real-time hole depth coefficient is within the standard hole depth coefficient range, it indicates that the state of the deep hole at this time is roughly the same as the initial setting, so there is no need to adjust the initial inclination angle of each lamp panel, and when the real-time hole depth coefficient is not within the standard hole depth coefficient range, the inclination angle of each lamp panel is adjusted according to the determination, which can effectively reduce the shielding of the lamp panel light source by the deep hole wall and improve the effect of the lamp panel light source on the UV glue in the deep hole, thereby improving the curing efficiency of the UV glue.

[0045] Further, when the real-time hole depth coefficient is greater than the standard hole depth coefficient range, it indicates that the current deep hole is relatively deep, so the initial inclination angle of the lamp panel is reduced by controlling the telescopic rod to contract, thereby reducing the shielding of the lamp panel light source by the hole wall and ensuring the curing efficiency of the light source device on the UV glue.

[0046] Especially, by determining the image glue point area of the UV glue in the real-time operation image, the light source device can automatically adapt to different UV glue points with different dispensing amounts in different deep holes, when the real-time image glue point area is large, the lamp panel is swung by repeatedly contracting and elongating the telescopic rod, which can eliminate the error of the inclination angle adjustment of the lamp panel on one hand and effectively irradiate the UV glue uniformly on the other hand, thereby ensuring uniform curing of the UV glue and improving the curing quality of the UV glue.

[0047] Further, when the real-time hole depth coefficient is less than the standard hole depth coefficient range, it indicates that the current deep hole is relatively shallow, so the initial inclination angle of the lamp panel is increased by controlling the telescopic rod to elongate, and the maximum inclination angle is determined in combination with the structure of the lamp panel to avoid reaching the adjustment blind area and ensure the stable operation of the light source device.

[0048] Especially, by calculating the real-time gray change rate through the gray processing of the real-time operation image, the curing condition of the UV glue in the deep hole can be quickly determined. When the UV glue is not cured, the surface glossiness is high, and the gray value in the corresponding image is also high. When the UV glue is completely cured or is about to be completely cured, the surface glossiness will gradually weaken, and the corresponding image gray value will also decrease. Therefore, the curing rate of the UV glue can be accurately shown according to the real-time gray change rate, and the light source output power of the lamp panel is adjusted according to the real-time gray change rate, so that the UV glue can be completely cured within the set time, and the curing quality of the UV glue is improved.

[0049] Especially, after adjusting the light source output power of the lamp panel, the heat dissipation will be further increased, so the heat dissipation output power of the heat dissipation fan is matched and adjusted through the set power matching parameter, the temperature in the shell is stabilized, and the power matching parameter is corrected according to the actual temperature in the shell, so that the heat generation of the lamp panel and the heat dissipation of the heat dissipation fan are relatively balanced, and the operation stability of the light source device is further ensured.

The heat dissipation output power of the heat dissipation fan is matched and adjusted according to the set power matching parameter and the adjusted light source output power.

[0066] By arranging the top plate with a plurality of rectangular hollows, a plurality of lamp panel assemblies can be loaded at the same time, the concentrated irradiation curing operation of multiple light sources is realized, and each lamp panel is independently arranged and has a heat sink, which ensures the stable operation of the lamp panel.

The heat dissipation fan of the present embodiment can provide an air extraction mode and a blowing mode, which can be selected according to the operation demand and the operation environment in actual production.

[0068] Please continue to refer to Figure 3 and Figure 4 As shown in the figure, wherein, Figure 3 is a schematic diagram of the conventional deep hole UV glue curing light of the present embodiment, Figure 4 is a schematic diagram of the light source device deep hole UV glue curing light of the present embodiment, including a deep hole structure 101, a UV glue point position 102, a conventional curing light 103, and a light source device curing light 104,

[0069] Further, the central control module is provided with a standard hole depth coefficient range and an initial inclination angle, the central control module can acquire a real-time working image collected by the solidification collection element, acquire a real-time hole diameter of the deep hole where the UV glue to be solidified is located in the real-time working image, and calculate a real-time hole depth coefficient according to the real-time hole depth distance measured by the infrared range finder and the real-time hole diameter, the central control module judges the real-time hole depth coefficient according to the standard hole depth coefficient range,

[0070] If the real-time hole depth coefficient is within the standard hole depth coefficient range, the central control module does not adjust the initial inclination angle of the lamp panel in each lamp panel assembly.

[0071] If the real-time hole depth coefficient is less than the standard hole depth coefficient range, the central control module judges the real-time hole depth distance of the deep hole where the UV glue to be solidified is located to determine the adjustment of the initial inclination angle of the lamp panel in each lamp panel assembly.

[0072] If the real-time hole depth coefficient is greater than the standard hole depth coefficient range, the central control module judges the real-time hole depth coefficient according to the maximum hole depth coefficient to determine the adjustment of the initial inclination angle of the lamp panel in each lamp panel assembly.

[0073] Wherein, As=Lh / Ld, As is the real-time hole depth coefficient, Lh is the real-time hole depth distance, and Ld is the real-time hole diameter.

[0074] By calculating the real-time hole depth coefficient of the UV glue to be solidified in the deep hole, the state of the deep hole where the UV glue to be solidified is located is determined, and it is determined whether to adjust the initial inclination angle of each lamp panel. When the real-time hole depth coefficient is within the standard hole depth coefficient range, it is indicated that the state of the deep hole at this time is roughly the same as the initial setting, so it is not necessary to adjust the initial inclination angle of each lamp panel. When the real-time hole depth coefficient is not within the standard hole depth coefficient range, the inclination angle of each lamp panel is adjusted according to the judgment, which can effectively reduce the shielding of the lamp panel light source by the deep hole wall and improve the effect of the lamp panel light source on the UV glue in the deep hole, thereby improving the solidification efficiency of the UV glue.

[0075] In the embodiment, the standard hole depth coefficient range is affected by the lamp panel size, the light source irradiation position, and the deep hole shape, and is usually set to 0.8 to 1.2. The initial inclination angle of each lamp panel on the shell is 45 degrees.

[0076] Further, the central control module is provided with a maximum hole depth coefficient and a minimum inclination angle of the lamp panel, the central control module compares the real-time hole depth coefficient with the maximum hole depth coefficient when judging that the real-time hole depth coefficient is greater than the standard hole depth coefficient range,

[0077] If the real-time hole depth coefficient is greater than or equal to the maximum hole depth coefficient, the central control module controls the telescopic rod to retract, so that the initial inclination angle of the lamp panel is reduced to the minimum inclination angle.

[0078] If the real-time hole depth coefficient is less than the maximum hole depth coefficient, the central control module will calculate a first modified tilt angle according to the real-time hole depth coefficient and the standard hole depth coefficient range, and control the telescopic rod to retract, so that the initial tilt angle of the lamp plate is reduced to the first modified tilt angle;

[0079] Wherein, Cx=Ce×[1-(As-Ap) / Ap], Ap=(Am+An) / 2, Cx is the first modified tilt angle, Ce is the initial tilt angle, As is the real-time hole depth coefficient, Am is the maximum value of the standard hole depth coefficient range, An is the minimum value of the standard hole depth coefficient range, and Ap is the intermediate value of the standard hole depth coefficient range.

[0080] When the real-time hole depth coefficient is greater than the standard hole depth coefficient range, it indicates that the current deep hole is relatively deep, so by controlling the telescopic rod to retract, the initial tilt angle of the lamp plate is reduced, thereby reducing the shielding of the hole wall to the lamp plate light source. At the same time, in combination with the determination of the minimum tilt angle of the lamp plate, the adjustment blind area of the lamp plate tilt angle is avoided. Here, it is limited by the structure setting and related to the length and setting position of the telescopic rod. Generally, in order to guarantee the relative distance between the lamp plate and the bottom of the deep hole, the minimum tilt angle is not less than 25 degrees.

[0081] Further, the central control module is provided with a standard glue point area. When the lamp plate irradiates and cures the UV glue in the deep hole at the minimum tilt angle or the first modified tilt angle, the central control module will acquire the image glue point area of the UV glue in the real-time operation image, and determine the image glue point area according to the standard glue point area,

[0082] If the image glue point area is less than or equal to the standard glue point area, the central control module does not control the lamp plate to swing adjustment;

[0083] If the image glue point area is greater than the standard glue point area, the central control module will calculate a swing tilt angle according to the image glue point area and the standard glue point area, and control the lamp plate to swing adjustment by adjusting the contraction and elongation of the telescopic rod.

[0084] Further, the central control module controls the contraction and elongation of the telescopic rod according to the swing tilt angle. The central control module controls the telescopic rod to retract to the swing upper limit tilt angle and then to elongate, and controls the telescopic rod to elongate to the swing lower limit tilt angle and then to retract;

[0085] Wherein, Cr=Cq×[(St-Sb) / St], C1=Cq-Cr, C2=Cq+Cr, Cr is the swing tilt angle, Cq is the current tilt angle of the lamp panel, the current tilt angle of the lamp panel is equal to the minimum tilt angle or the first corrected tilt angle, C1 is the upper limit tilt angle of the swing, C2 is the lower limit tilt angle of the swing, St is the image dot area, Sb is the standard dot area.

[0086] By determining the image dot area of the UV glue in the real-time operation image, the light source device can automatically adapt to different point glue amounts of the UV glue in different deep holes. The image dot area is set according to the standard operation dot area of the lamp panel under normal circumstances, and is generally set to be between 0.15-0.27 square centimeters. When the real-time image dot area is larger, the lamp panel is swung by repeatedly contracting and extending the telescopic rod, which can eliminate the error of the tilt angle adjustment of the lamp panel, and effectively make the UV glue be uniformly irradiated, thereby ensuring the uniform curing of the UV glue and improving the curing quality of the UV glue.

[0087] Further, the central control module is provided with a standard hole depth distance and a maximum tilt angle of the lamp panel. When the real-time hole depth coefficient is less than the standard hole depth coefficient range, the central control module determines the real-time hole depth distance according to the standard hole depth distance,

[0088] If the real-time hole depth distance is less than or equal to the standard hole depth distance, the central control module controls the telescopic rod to extend, so that the initial tilt angle of the lamp panel is increased to the maximum tilt angle.

[0089] If the real-time hole depth distance is greater than the standard hole depth distance, the central control module calculates a second corrected tilt angle according to the real-time hole depth coefficient and the standard hole depth coefficient range, and controls the telescopic rod to extend, so that the initial tilt angle of the lamp panel is increased to the second corrected tilt angle.

[0090] Wherein, Cv=Ce×[1+(Ap-As) / Ap], Ap=(Am+An) / 2, Cv is the second corrected tilt angle, Ce is the initial tilt angle, As is the real-time hole depth coefficient, Am is the maximum value of the standard hole depth coefficient range, An is the minimum value of the standard hole depth coefficient range, and Ap is the intermediate value of the standard hole depth coefficient range.

[0091] Similarly, when the real-time hole depth coefficient is less than the standard hole depth coefficient range, it indicates that the current deep hole is relatively shallow, so that the initial tilt angle of the lamp panel is increased by controlling the telescopic rod to extend, and the maximum tilt angle is determined by setting the structure of the lamp panel, so as to avoid reaching the adjustment blind area. Generally, the maximum tilt angle is set to be higher than 70 degrees, and the standard hole depth distance is set to be not more than the length of the lamp panel, about 30 mm.

[0092] Further, the central control module is provided with a standard gray scale change rate. When the lamp plate irradiates the UV glue in the deep hole, the central control module performs gray scale processing on the obtained real-time operation image, obtains the real-time glue point gray scale of the UV glue in the image, calculates the real-time gray scale change rate, and judges the real-time gray scale change rate according to the standard gray scale change rate.

[0093] If the real-time gray scale change rate is less than the standard gray scale change rate, the central control module adjusts the light source output power of the lamp plate.

[0094] If the real-time gray scale change rate is greater than or equal to the standard gray scale change rate, the central control module does not adjust the light source output power of the lamp plate.

[0095] Wherein, Vs= (G2-G1) / t, Vs is the real-time gray scale change rate, t is the unit detection time set in the central control module, G2 is the real-time glue point gray scale of the UV glue in the current real-time operation image, and G1 is the real-time glue point gray scale of the UV glue in the real-time operation image before the unit detection time t; Pg'= Pg x (Vs / Vb), Pg is the light source output power before adjustment, Pg' is the light source output power after adjustment, and Vb is the standard gray scale change rate.

[0096] By calculating the real-time gray scale change rate through gray scale processing of the real-time operation image, the curing condition of the UV glue in the deep hole can be quickly determined. When the UV glue is not cured, the surface glossiness is high, and the gray scale value in the corresponding image is also high. When the UV glue is completely cured or is about to be completely cured, the surface glossiness gradually weakens, and the corresponding image gray scale value also decreases. Therefore, the curing rate of the UV glue can be accurately shown according to the real-time gray scale change rate, and the light source output power of the lamp plate is adjusted according to the real-time gray scale change rate, so that the UV glue can be completely cured within the set time, and the curing quality of the UV glue is improved.

[0097] In the embodiment, the image gray scale value changes between 70 and 90 before and after the UV glue is cured, and the corresponding UV glue curing time is 60 seconds. Therefore, the standard gray scale change rate is not less than 1.17 per second, and the unit detection time t should not be higher than 2 seconds to ensure the accuracy of the adjustment.

[0098] Further, the central control module is provided with a power matching parameter. After the central control module adjusts the light source output power of the lamp plate, the cooling output power of the cooling fan is matched and adjusted according to the adjusted light source output power and the power matching parameter.

[0099] Wherein, Pf=Q*Pg', Pf is the heat dissipation output power after matching adjustment, Pg' is the light source output power after adjustment, Q is the power matching parameter, the power matching parameter is related to the heat generation of the lamp panel and the heat dissipation efficiency of the heat dissipation fan, and is generally set to about 1.

[0100] Further, the central control module is provided with a first preset temperature and a second preset temperature, the temperature sensing element can detect the real-time temperature of the radiator, and the central control module compares the real-time temperature with the first preset temperature and the second preset temperature,

[0101] If the real-time temperature of the radiator is less than the first preset temperature, the central control module adjusts the power matching parameter to a first power matching parameter;

[0102] If the real-time temperature of the radiator is greater than or equal to the first preset temperature and less than or equal to the second preset temperature, the central control module does not adjust the power matching parameter;

[0103] If the real-time temperature of the radiator is greater than the second preset temperature, the central control module adjusts the power matching parameter to a second power matching parameter;

[0104] Wherein, Q1=Q-[Q*(T1-Ts) / T1], Q2=Q+[Q*(Ts-T2) / Ts], Q is the power matching parameter, Q1 is the first power matching parameter after adjustment, Q2 is the second power matching parameter after adjustment, T1 is the first preset temperature, T2 is the second preset temperature, and Ts is the real-time temperature of the radiator.

[0105] After adjusting the light source output power of the lamp panel, the heat dissipation will be further increased, so the power matching parameter is set to correspond to the heat dissipation output power of the heat dissipation fan, to ensure the stability of the temperature in the shell, and the power matching parameter is corrected according to the actual temperature in the shell, so that the heat generation of the lamp panel and the heat dissipation of the heat dissipation fan are relatively balanced, further ensuring the stable operation of the light source device.

[0106] Further, the lamp panel is rectangular, and one side of the lamp panel is connected to one side of the rectangular hollow part on the top plate through a hinge, the lamp panel can be rotated relative to the top plate about the hinge to adjust the inclination angle, and the inclination angle of the lamp panel is the included angle between the lamp panel and the horizontal direction.
