Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

[0064] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0065] Example 1

[0066] Figure 1 This is a step diagram of the LED lamp production process provided in this embodiment. Please refer to Figure 1 This embodiment provides a LED lamp production process, which includes:

[0067] S01: Power on the unpackaged LED lamp to perform a lamp burning operation.

[0068] S02: Determine whether VOC elimination of the LED lamp is achieved.

[0069] Figure 2 This is a step diagram of step S02 in the LED lamp production process provided in this embodiment. Figure 1 and Figure 2 In this embodiment, the above step S02 includes:

[0070] S21: Obtain a brightness value representing the brightness of the LED light.

[0071] Specifically, the brightness value at the moment when the LED lamp is powered on is recorded and used as the initial brightness value. That is, the initial brightness value represents the brightness of the LED lamp at the first moment, and the first moment is the moment when the LED lamp is powered on. The brightness value obtained in real time after the initial brightness value is the real-time brightness value, that is, the real-time brightness value represents the brightness of the LED lamp at the second moment, and the second moment is after the first moment.

[0072] S22: Obtaining the duration of the lamp burning operation. The duration of the lamp burning operation is the duration from the moment when the LED lamp is powered on (the first moment) to the moment when the real time is obtained.

[0073] S23: Determine whether VOC elimination of the LED lamp is achieved based on the relationship between the real-time brightness value and the initial brightness value in the brightness value and the duration of the lamp burning operation.

[0074] Specifically, during the lamp burning process, after obtaining the real-time brightness value, the real-time brightness value is compared with the initial brightness value. When the real-time brightness value is greater than or equal to the initial brightness value, it can be determined that VOC elimination of the LED lamp is achieved. Figure 3 The relationship between the brightness value and time during the lamp burning process provided in this embodiment is as follows: Figure 3 The various curves in the figure are obtained by the inventors by burning LED lamps of different types and specifications before packaging. Figure 3As shown in the curve, after the real-time brightness value is greater than or equal to the initial brightness value, the brightness of the LED lamp does not change much when the lamp burning operation is continued, indicating that the VOC of the LED lamp has been basically eliminated at this time.

[0075] At the same time, in actual production, in order to avoid the problem that some LED lamps cannot achieve the condition that the real-time brightness value is greater than or equal to the initial brightness value after a long period of burning-in operation, whether the VOC exclusion of the LED lamp is achieved is also judged based on the burning-in operation duration.

[0076] When the duration of the lamp burning operation is less than the first preset duration, if the real-time brightness value is greater than or equal to the initial brightness value, it is determined that the LED lamp has been eliminated. In other words, when the time when the acquired real-time brightness value is greater than or equal to the initial brightness value is earlier than the time when the duration of the lamp burning operation reaches the first preset duration, it is determined that the LED lamp has been eliminated.

[0077] On the contrary, when the duration of the lamp burning operation is greater than or equal to the first preset duration, if the real-time brightness value is less than the initial brightness value, the LED lamp is judged to be a defective lamp, and the LED lamp is powered off.

[0078] It can be understood that the specific value of the first preset time length can be set according to the type and specification of the LED lamp, for example, the first preset time length is set to 10 hours.

[0079] Obviously, when the acquired duration of the lamp burning operation is less than the first preset duration and the real-time brightness value is less than the initial brightness value, the LED lamp continues to perform the lamp burning operation.

[0080] It should be noted that, in this embodiment, in order to prevent the existence of defective lamps from interfering with the judgment of whether VOC elimination of the LED lamp is achieved, during the lamp burning operation, the brightness value of the LED lamp and the duration of the lamp burning operation are obtained at the same time. It can be understood that in other embodiments, only the brightness value of the LED lamp can be obtained, and the VOC elimination of the LED lamp can be judged based on the comparison between the real-time brightness value and the initial brightness value.

[0081] Specifically, this embodiment does not limit the order of steps S01 and S21. Steps S01 and S21 may be performed simultaneously, or step S21 may be performed before step S01.

[0082] S03: Cut off the power supply to the LED lamp.

[0083] At the end of step S02, when it is determined that the VOC elimination of the LED lamp is achieved, the LED lamp is powered off, that is, the lamp burning operation is completed at this time, and subsequent processing can be performed, such as packaging the LED lamp.

[0084] It should also be noted that, understandably, in other embodiments, it is also possible to determine whether the VOC of the LED lamp is eliminated by other means.

[0085] As an example, Figure 4 Another step diagram of the LED lamp production process provided by this embodiment is shown. Figure 3 , step S02 includes:

[0086] S21a: Obtain the duration of the lamp burning operation.

[0087] S22a: If the duration of the lamp burning operation is greater than or equal to the second preset duration, it is determined that VOC elimination of the LED lamp is achieved.

[0088] Specifically, the second preset duration can be obtained through a test before the burn-in operation is performed. For example, when a large number of LED lamps are produced, a burn-in test is performed on the LED lamps before production to obtain the relationship between the brightness value of the LED lamp and the burn-in duration (for example, Figure 3 The curve shown in FIG. 1 is then used to determine the second preset duration as the duration of burning the LED lamp after the real-time brightness value of the LED lamp is greater than the initial brightness value.

[0089] Optionally, the second preset time is 8 hours, that is, after 8 hours of the lamp burning operation, it can be determined that the VOC elimination of the LED lamp is achieved, at which time the LED lamp can be powered off and the lamp burning operation is completed. It can be understood that the specific value of the second preset time can also be set according to the type and specification of the LED lamp.

[0090] In this method, the VOC elimination in the LED lamp is determined by the preset burning time of the LED lamp, in order to avoid the situation that the VOC in individual LED lamps is not actually eliminated, thereby affecting the qualified rate of the produced LED lamps. Furthermore, the LED lamp production process also includes:

[0091] S04: performing a burn-in operation again for a third preset time on the LED lamp with the shadow on the surface.

[0092] Specifically, the appearance of the LED lamp that has been burned in is observed to check whether there is a shadow on the surface of the LED lamp. Optionally, the LED lamp can be photographed to obtain image information representing the appearance of the current LED lamp, and the image information can be compared with a preset image of an LED lamp with no shadow on the surface, so as to determine whether there is a shadow on the surface of the LED lamp.

[0093] If there is a shadow on the surface of the LED lamp, the LED lamp is powered on again to perform a second burn-in operation, and the duration of the second burn-in operation is a third preset duration. Optionally, the third preset duration is 3 hours. It is understandable that in other embodiments, the specific value of the third preset duration can also be set according to requirements. If there is no shadow on the surface of the LED lamp, it can be subsequently processed, such as packaging the LED lamp.

[0094] It should be noted that the method for checking whether there is a shadow on the surface of the LED lamp is not limited here. It can be understood that in other embodiments, other methods can also be used.

[0095] In this embodiment, in order to ensure the reliable implementation of the lamp burning operation and avoid damage to the LED lamp caused by the lamp burning operation, optionally, during the lamp burning operation, a step of controlling the temperature of the LED lamp is also included to control the temperature of the LED lamp to be within a preset temperature range.

[0096] Specifically, the step of controlling the temperature of the LED lamp may include: obtaining the temperature of the LED lamp during the burning process, and determining the heat dissipation efficiency according to the relationship between the temperature of the LED lamp and the preset temperature range, so as to control the temperature of the LED lamp within the preset temperature range. For example, when the temperature of the LED lamp reaches a certain proportion of the lowest temperature in the preset temperature range, the LED lamp may be cooled, and the heat dissipation efficiency may be controlled in real time.

[0097] Specifically, the preset temperature can be determined according to the following formula:

[0098] T=IVu+T1-C;

[0099] Among them, I is the operating current, V is the operating voltage, u is the empirical coefficient, T1 is the actual measured temperature of the LED lamp at rated current, and C is a constant.

[0100] Optionally, u is 1.1 and C is 40.

[0101] Example 2

[0102] This embodiment also provides an LED lamp, which is manufactured by the LED lamp production process provided in Embodiment 1. That is, the LED lamp has basically completed VOC removal before packaging, and there is basically no VOC phenomenon during use after packaging.

Figure 5 and Figure 6 This embodiment provides a lamp burning device 100, which is used to burn out an unpackaged LED lamp 300.

[0105] The lamp burning device 100 includes a carrier 110, an electrical connector (not shown) disposed on the carrier 110, and a controller 120 communicating with the electrical connector. The carrier 110 has a placement area for holding the LED lamp 300. When in use, the unpackaged LED lamp 300 is placed in the placement area, and the LED lamp 300 is powered on and off by the electrical connector under the control of the controller 120, so as to eliminate VOC of the LED lamp 300 by performing a lamp burning operation on the LED lamp 300, thereby avoiding the possibility of VOC phenomenon during the use of the LED lamp 300 after the LED lamp 300 is packaged to form a finished product of the LED lamp 300, thereby reducing the problem of the surface of the lamp bead becoming dark and the light output rapidly deteriorating due to the appearance of VOC during the use of the LED lamp 300.

[0106] Specifically, the controller 120 of the lamp burning device 100 executes multiple steps of the LED lamp 300 production process provided in the embodiment. That is, the controller 120 is used to control the electrical connection to power on the LED lamp 300 to perform the lamp burning operation, and to determine whether the VOC elimination of the LED lamp 300 is achieved. If it is achieved, the controller 120 controls the electrical connection to power off the LED lamp 300.

[0107] The lamp burning device 100 provided in this embodiment is further described below:

[0108] Figure 7 This is a schematic diagram of the explosion structure of the lamp burning device 100 provided in this embodiment. Figure 5-Figure 7 In this embodiment, the carrier 110 includes a frame 111 and a first heat dissipation structure 112 installed on the frame 111, and the placement area is formed on the first heat dissipation structure 112, so that the LED lamp 300 is cooled by the first heat dissipation structure 112 during the lamp burning operation.

[0110] Optionally, the first heat dissipation structure 112 includes a heat sink 1122 and a heat dissipation pad 1121.

[0112] Furthermore, the first heat dissipation structure 112 further includes a first heat dissipation fan 1124, which is used to generate an airflow through the heat sink 1122 to improve the heat dissipation efficiency of the heat sink 1122. At the same time, the first heat dissipation fan 1124 is electrically connected to the controller 120, so that the controller 120 controls the rotation speed of the first heat dissipation fan 1124 to control the heat dissipation efficiency of the LED lamp 300 during the burning operation, so that the temperature of the LED lamp 300 is within a preset temperature range during the burning operation.

[0113] Specifically, the first cooling fan 1124 is arranged on one side of the extension direction of the cooling fins 1123, that is, the first cooling fan 1124 and the cooling fins 1122 are distributed along the width direction of the frame 111, and the airflow generated by the first cooling fan 1124 passes through the wall surface of the cooling fins 1123, thereby taking away the heat at the cooling fins 1123. The controller 120 includes a temperature control circuit board 121, which is electrically connected to the first cooling fan 1124 to control the rotation speed of the first cooling fan 1124 through the temperature control circuit board 121.

[0114] Furthermore, the lamp burning device 100 further includes a temperature sensor, which is electrically connected to the temperature control circuit board 121 to detect the temperature of the LED lamp 300, and sends an electrical signal representing the temperature of the LED lamp 300 to the temperature control circuit board 121.

Figure 5-Figure 8 In this embodiment, the lamp burning device 100 further includes a fixing member 141 movably connected to the carrier 110. The fixing member 141 can be switched between a pressing position and a releasing position by the movement of the fixing member 141 relative to the carrier 110. When the fixing member 141 is in the pressing position, the fixing member 141 is located directly above the placement area to fix the LED lamp 300 in the placement area. When the fixing member 141 is in the releasing position, the fixing member 141 is away from the placement area, so that the LED lamp 300 can be placed in the placement area or the LED lamp 300 in the placement area can be taken out.

[0118] Optionally, when the fixing member 141 is in the loosened position, the projection of the fixing member 141 on the plane where the placement area is located in the vertical direction is spaced from the placement area. Specifically, the plane where the placement area is located is parallel to the upper end surface of the support plate 1111. When the fixing member 141 is in the loosened position, the projection of the fixing member 141 on the support plate 1111 in the vertical direction is located between the placement area and the setting position of the temperature control circuit board 121.

[0119] Fig. 9 for Figure 6 The enlarged schematic diagram of the local structure at Ⅸ in the middle. Please refer to Figure 5-Figure 9 In this embodiment, it also includes a rotating shaft support 142 and a connecting block 143, one end of the connecting block 143 is rotatably connected to the rotating shaft support 142, and the other end is fixedly connected to the fixing member 141, so that the fixing member 141 can be rotated around the rotating shaft support 142 by pushing the fixing member 141. The fixing member 141 can be switched between the loose position and the pressing position by rotating the fixing member 141.

[0120] Specifically, the fixing member 141 is a long strip block extending along the length direction of the frame 111, and multiple LED lamps 300 can be burned at the same time through the fixing member 141. There are two rotating shaft supports 142 and two connecting blocks 143, respectively, so as to form two sets of rotating connection structures, that is, each set includes a rotating shaft support 142 and a connecting block 143, and the two sets of rotating connection structures are respectively arranged on both sides of the length direction of the fixing member 141, so as to ensure the rotation reliability of the fixing member 141 through the coordinated use of the two sets of rotating connection structures.

[0121] Optionally, a handle 145 is provided on the fixing member 141. When in use, the fixing member 141 is pushed or pulled by holding the handle 145 to switch the position of the fixing member 141. It is understandable that in other embodiments, the position switching operation mode of the fixing member 141 can also be set according to needs, for example, a driving member electrically connected to the controller 120 is provided, so as to drive the fixing member 141 to switch the position under the control of the controller 120.

[0122] Furthermore, it also includes a pressing structure 150, which has a locked state and an unlocked state. When the fixing member 141 is in the pressing position and the pressing structure 150 is in the locked state, part of the pressing mechanism presses against the fixing member 141, thereby locking the fixing member 141 in the pressing position, ensuring that the LED lamp 300 is pressed against the heat dissipation pad 1121, which helps to ensure the heat dissipation effect of the LED lamp 300. When the pressing structure 150 is in the unlocked state, the fixing member 141 can move relative to the frame 111 under the action of an external force.

[0123] Specifically, the covering structure 150 is a piston-like structure, which includes a shell 151 and a locking rod 152 movably arranged in the shell 151. When the covering structure 150 is in a locked state, one end of the locking rod 152 extends out of the shell 151 and is pressed against the fixing member 141. When the covering structure 150 is in an unlocked state, the end of the locking rod 152 retracts into the shell 151, so that the locking rod 152 is separated from the fixing member 141, and the fixing member 141 can move relative to the frame 111 under the action of external force.

[0124] Optionally, a protrusion 144 is provided on the fixing member 141, and the upper end surface of the protrusion 144 is an inclined surface. Accordingly, the lower end surface of one end of the locking rod 152 used to cooperate with the fixing member 141 is set as an inclined surface, and the two inclined surfaces fit together to apply an inclined downward pressure to the fixing member 141 through the locking rod 152, thereby locking the fixing member 141 in the clamping position.

[0125] Please refer to it again Figure 5-Figure 8 In this embodiment, the lamp burning device 100 further includes a photoresistor 161 electrically connected to the controller 120. The photoresistor 161 is used to detect the brightness value of the LED lamp 300 and send an electrical signal representing the brightness value to the controller 120. The controller 120 is used to determine whether the VOC elimination of the LED lamp 300 is achieved according to the electrical signal.

[0126] Specifically, the fixing member 141 is provided with a first through hole 146 corresponding to the light-emitting area of ​​the LED lamp 300, and the photoresistor 161 and the LED lamp 300 are respectively arranged on both sides of the first through hole 146. During the lamp burning operation, the light emitted by the LED lamp 300 is transmitted to the photoresistor 161 through the first through hole 146. The controller 120 includes a light-controlled circuit board 122 arranged on the upper side of the photoresistor 161, and the photoresistor 161 is electrically connected to the light-controlled circuit board 122. The photoresistor 161 sends an electrical signal representing the brightness value of the LED lamp 300 to the light-controlled circuit board 122, so that the initial brightness value of the LED lamp 300 is recorded through the light-controlled circuit board 122, and the real-time brightness value is compared with the initial brightness value, so as to judge whether the VOC elimination of the LED lamp 300 is achieved.

[0127] It can be understood that, at the same time, the controller 120 also includes a power supply circuit board (not shown) electrically connected to the electrical connection, and the power supply circuit board is electrically connected to the light control circuit board 122, so as to control the electrical connection to cut off the power to the LED lamp 300 according to the judgment result of the light control circuit board 122. Obviously, in other embodiments, the power supply control module can also be integrated on the light control circuit board 122, and the light control circuit board 122 can be used to realize the control of the power on and off of the LED lamp 300.

[0128] Furthermore, the lamp burning device 100 also includes a matte sheet 162 arranged on the side of the photoresistor 161 close to the placement area. The matte sheet 162 is used to weaken the light before it is transmitted to the photoresistor 161, that is, the light emitted by the LED lamp 300 is transmitted to the photoresistor 161 after being weakened by the matte sheet 162.

[0129] Specifically, a matte sheet mounting frame 163 is further provided on the upper side of the fixing member 141, and a second through hole communicating with the first through hole 146 is opened on the matte sheet mounting frame 162. The first through hole 146 and the second through hole form an optical path channel, and the matte sheet 162 is installed in the second through hole.

[0130] Furthermore, the lamp burning device 100 further includes a light intensity protection cover 164, through which the placement area and the photoresistor 161 are covered, so that the light generated by the LED lamp 300 located in the placement area during the lamp burning operation is confined in the light intensity protection cover 164 to prevent light damage. Specifically, when the fixing member 141 is in the pressed position, the fixing member 141 and the matte sheet mounting frame 163 and the matte sheet 162 thereon can all be covered in the light intensity protection cover 164.

[0131] According to a lamp burning device 100 provided in this embodiment, the working principle of the lamp burning device 100 is:

[0132] When in use, the unpackaged LED lamp 300 is placed in the placement area, that is, on the heat dissipation pad 1121, and the LED lamp 300 is connected to the electrical connector. Then the fixing member 141 is pulled to rotate relative to the frame 111, so that the fixing member 141 is in a pressing position, and the pressing structure 150 is operated so that the end of the locking rod 152 extends out of the housing 151 and presses on the protrusion 144 of the fixing member 141, so that the fixing member 141 is pressed in the pressing position, ensuring close contact between the LED lamp 300 and the heat dissipation pad 1121. The controller 120 controls the electrical connection to power on the LED lamp 300, so that the LED lamp 300 starts to emit light to perform the lamp burning operation. At the same time, the photoresistor 161 detects the brightness of the LED lamp 300. At the same time, the light control circuit board 122 records the initial brightness value of the LED lamp 300, and compares the subsequent real-time brightness value of the LED lamp 300 with the initial brightness value to determine whether the VOC elimination of the LED lamp 300 is achieved. If it is achieved, the controller 120 controls the electrical connection to power off the LED lamp 300, and the lamp burning operation is completed. At the same time, during the lamp burning operation, the temperature control circuit board 121 controls the speed of the first cooling fan 1124 according to the temperature of the LED lamp 300, and then controls the heat dissipation efficiency of the first heat dissipation structure 112 to the LED lamp 300, so that the temperature of the LED lamp 300 is maintained within a preset temperature range.

[0133] The lamp burning device 100 provided in this embodiment has at least the following advantages:

[0134] The burning device 100 provided in the embodiment of the present invention performs a burning operation on an unpackaged LED lamp 300, thereby eliminating VOCs of the LED lamp 300 in advance, so that the finished LED lamp 300 produced by subsequent packaging will hardly generate VOCs during use, and the LED lamp 300 has high brightness, good stability, and good user experience. At the same time, by detecting temperature and light, effective control of the burning operation is achieved, ensuring the burning effect.
