[0029] Example 1

[0030] See also Figure 1 ,in Figure 1 : is a structural schematic diagram of a light source device screening lighting control device. This embodiment provides a light source device screening lighting control device, including:

[0031] A circuit board 1, wherein a power supply circuit 2 is provided on the circuit board 1, and the power supply circuit 2 includes a white light circuit 21 and a purple light circuit 22;

[0032] A light source setting module 3, the light source setting module 3 includes a plurality of white light pads 31 and a purple light pad 32, the white light pads 31 and the purple light pads 32 are arranged on the circuit board 1; a plurality of the white light pads 31 are respectively connected to the white light circuit 21, and the white light pads 31 can be connected to set a white light source device; a plurality of the purple light pads 32 are respectively connected to the purple light circuit 22, and the purple light pads 32 can be connected to set a purple light source device; and

[0033] A power connection module, the power connection module includes a positive electrode pad 41 and a negative electrode pad 42; the positive electrode pad 41 is simultaneously connected to all the white light lines 21 and all the purple light lines 22; at least two negative electrode pads 42 are provided, which are respectively connected to the white light line 21 and the purple light line 22, and the power connection module can be connected to an external power supply to drive the white light source device arranged on the white light pad 31 and / or the purple light source device on the purple light pad 32 to emit light.

[0034] It can be understood that the circuit board 1 and the power supply line 2 can be set by printing or other conventional methods. At the same time, the white light line 21 and the purple light line 22 are just called differently in name, which only represents the distinction of their functional roles. The lines themselves can be of the same structure and method, and can be distinguished by printing lines of different colors when necessary. No further detailed description is given here.

[0035] It is understandable that the white light pad 31, the purple light pad 32 and other pads themselves are conventional pads, which will not be described in detail here. Those skilled in the art can select pad materials according to actual needs. The white light source device mainly refers to a light source device that can emit white light after being powered on. In this embodiment, it is preferably an LED light source device, which can be the LED light source device to be detected in the present utility model, specifically a light emitting diode. In other embodiments of the present utility model, it can also be other conventional lamps, such as fluorescent lamps and halogen lamps. The purple light source device is similar, which will not be described in detail here.

[0036] It can be understood that the positive electrode pad 41 and the negative electrode pad 42 correspond to the positive and negative electrodes of the external power controller and the external power supply respectively, which is equivalent to controlling the connection relationship between the positive electrode pad 41 and the negative electrode pad 42 and the external power supply through the external power controller to control the lighting to be turned off or the white light or purple light to be emitted or both lights to be emitted at the same time. The external power controller can be a power switch or other conventional control device. More details are not further described here. Those skilled in the art can understand and implement it based on the above description combined with the common knowledge of the prior art.

[0037] In this embodiment, there are several white light lines 21 and several purple light lines 22, and the two lines are staggered in sequence; the positive electrode pad 41 is connected to the head ends of all the white light lines 21 and all the purple light lines 22 at the same time; there are two negative electrode pads 42, namely a first negative electrode pad 421 and a second negative electrode pad 422, the first negative electrode pad 421 is connected to the ends of several white light lines 21, and the second negative electrode pad 422 is connected to the ends of several purple light lines 22.

[0038] Specifically, Figure 1 As shown in FIG. 1 , a plurality of white light lines 21 and purple light lines 22 are arranged horizontally on the circuit board, and the head end ( Figure 1 (center left end) All white light lines 21 and purple light lines 22 are connected together, and then connected to the positive electrode pad 41 through a longer line. The first negative electrode pad 421 and the second negative electrode pad 422 are respectively connected to the white light line 21 and the purple light line 22 through the power supply line 2, so that the white light source devices on all white light lines 21 can be controlled by the first negative electrode pad 421, and the purple light source devices on all purple light lines 22 can be controlled by the second negative electrode pad 422. In essence, it is equivalent to connecting each white light line 21 in parallel with each other, and each purple light line 22 in parallel with each other.

[0039] In this embodiment, the ends of the plurality of white light lines 21 ( Figure 1 A jumper connection pad 43 is provided on the middle right end, and the adjacent white light lines 21 are connected through the jumper connection pad 43, and at least one of the white light lines 21 is connected to the corresponding first negative electrode pad 421, and / or

[0040] Jumper connection pads 43 are provided at the ends of several of the purple light lines 22 , and adjacently spaced purple light lines 22 are connected via the jumper connection pads 43 , and at least one of the purple light lines 22 is connected to the corresponding second negative electrode pad 422 .

[0041] It is understandable that the power supply lines 2 with the same spacing distribution may not be directly connected, such as in this embodiment. Figure 1 The first white light line 211 and the second white light line 212 cannot be directly connected, so in this embodiment, by setting a jumper connection pad 43, the same power supply lines 2 at adjacent intervals can be connected by jumper connection pads 43.

[0042] In this embodiment, three white light lines 21 are provided, namely white light line No. 1 211, white light line No. 212 and white light line No. 3 213, and two purple light lines 22 are provided. The white light line No. 1 211 is provided in the middle of the circuit board 1, and one purple light line 22 is provided on each side, and the outer sides of the two purple light lines 22 are provided with the white light line No. 2 212 and the white light line No. 3 213 respectively.

[0043] In this embodiment, the ends of the second white light line 212 and the third white light line 213 are connected to each other, and the first negative electrode pad 421 is disposed between the connecting portions of the ends of the second white light line 212 and the third white light line 213 .

[0044] In this embodiment, the ends of the first white light line 211 and the second white light line 212 are both provided with the jumper connection pad 43 , and the ends of the first white light line 211 and the second white light line 212 are connected via the jumper connection pad 43 .

[0045] Specifically, in this embodiment, 3 white light lines and 2 purple light lines are taken as an example. In other embodiments, the specific number can also be exchanged. In this embodiment, a total of 5 power supply lines 2 are set as an example for explanation. If more power supply lines 2 are set, the same principle applies. The power supply lines that can be directly connected together are directly connected to the corresponding negative electrode pads 42. If they cannot be directly connected, the power supply lines 2 controlling the same color light sources are connected together by setting jumper connection pads 43. In this embodiment, the white light line 21 is set with a jumper connection pad 43 as an example. In other embodiments, the purple light line 22 can be set with a jumper connection pad 43, or both lines can be set with a jumper connection pad 43. The specific method can be adjusted and changed according to the actual number of lines and needs, and will not be further described here.

[0046] In this embodiment, if Figure 1 and Figure 2 As shown, Figure 2 In this embodiment Figure 1 An enlarged schematic diagram of part A, taking the white light pad 31 as an example, the white light pad 31 is composed of a left pad 311 and a right pad 312, and the two adjacent white light pads 31 are connected through the power supply line 2, and the power supply line 2 between the left pad 311 and the right pad 312 of a single white light pad 31 is disconnected, so as to connect the left pad 311 and the right pad 312 to form a circuit by welding the white light source device to the white light pad 31.

[0047] In addition, the purple light pads 32 are similarly composed of a left pad and a right pad, and the two adjacent purple light pads 32 are connected by the power supply line 2, and the power supply line 2 between the left pad and the right pad of a single purple light pad 32 is disconnected, so as to connect the left pad and the right pad to form a circuit after the purple light source device is soldered to the purple light pad 32.

[0048] Specifically, the white light source device and the purple light source device are preferably LED light source devices in this embodiment, which can be the LED light source device to be detected in the present invention, and can be a light emitting diode, the positive electrode and the negative electrode of which are respectively welded to the left pad 311 and the right pad 312 to complete the connection setting. For other types of settings, the principle is the same and will not be further described here.

[0049] The working process and principle of the light source device screening lighting control device of the utility model:

[0050] When controlling lighting, the external power controller controls whether to turn on the first negative electrode pad 421 or the second negative electrode pad 422, or both of them are turned on or off at the same time, so as to control the corresponding light source device to emit light of the corresponding color, which is used to illuminate the LED light source device to be tested, so that the user can perform appearance quality inspection on the LED light source device. Specifically, when it is necessary to detect large-size LED light source devices, the external power supply is controlled to connect the first negative electrode pad 421 and the positive electrode pad 41, and white light detection can be used; when it is necessary to screen and detect the product quality of small-size LED light source devices, the external power supply is controlled to connect the second negative electrode pad 422 and the positive electrode pad 41, and the purple light is turned on.

[0051] Due to the adoption of the above technical solution, the utility model has at least the following beneficial effects:

[0052] The light source device screening lighting control device provided by the utility model has two light sources, white light and purple light. When it is necessary to detect large-size LED light source devices, white light detection can be used; when it is necessary to screen and detect the product quality of small-size LED light source devices, turn on the purple light lighting lamp. The purple light has the effect of stimulating the stimulated emission of the plastic material of the LED light source device and the fluorescent glue in the cup of the LED light source device. If there is foreign matter on the plastic of the LED light source device or on the surface of the fluorescent glue of the LED light source device, the foreign matter can be found more clearly after the purple light irradiation, thereby effectively improving the effect of the appearance inspection of the screening of small-size LED light source devices, reducing the probability of misjudgment and omission in the traditional white light irradiation detection, and improving production efficiency.

[0053] Example 2

[0054] This embodiment also provides a lighting device, which includes the light source device screening lighting control device described in any one of the utility models, and also includes a white light source device and a purple light source device. The white light source device is welded on the white light pad, and the purple light source device is welded on the purple light pad.

[0055] It is understandable that the white light source device mainly refers to a light source device that can emit white light after being powered on. In this embodiment, it is preferably an LED light source device. In other embodiments of the utility model, it can also be other conventional lamps, such as fluorescent lamps and halogen lamps. The same is true for the purple light source device, which will not be described in detail here.

[0056] Furthermore, the lighting device can be connected to the power supply through an external power controller, the external power controller can be a power switch or other conventional control devices, the power supply can be an AC 220V power supply, or it can be other power supplies such as power banks and batteries. The external power controller and the power supply can also be arranged as a whole with the lighting device. More situations are not further described here.

[0057] In this embodiment, the peak wavelength of the ultraviolet light source device is 390-410nm. Specifically, after testing, the ultraviolet light with a peak wavelength of 390-405nm has a more obvious effect on the appearance of defects in the LED light source device, especially the 395-405nm ultraviolet light has an effect of stimulating the plastic material of the LED light source device and the fluorescent glue in the cup of the LED light source device to emit stimulated light.

[0058] In this embodiment, the color temperature of the white light source device is 3000K-8000K.

[0059] It should be noted that the lighting device in this embodiment can be made into a desk lamp, a fluorescent tube or other specific forms, which will not be further described here. Those skilled in the art can set the specific product form according to actual needs in combination with the existing technology. The focus is on the innovative technology included in the utility model. Others can refer to and use the existing technology for combination and implementation.

[0060] Due to the adoption of the above technical solution, the utility model has at least the following beneficial effects:

[0061] The lighting device provided by the utility model has two light sources, white light and purple light. When it is necessary to detect large-size LED light source devices, white light detection can be used; when it is necessary to screen and detect the product quality of small-size LED light source devices, turn on the purple light lamp. The purple light (especially the purple light in the peak range of 395-405nm) has the effect of stimulating fluorescence on the plastic material of the LED light source device and the fluorescent glue in the cup of the LED light source device. If there is foreign matter on the plastic of the LED light source device or on the surface of the fluorescent glue of the LED light source device, the foreign matter can be found more clearly after purple light irradiation, thereby effectively improving the effect of appearance inspection of screening small-size LED light source devices, reducing the probability of misjudgment and omission in traditional white light irradiation detection, and improving production efficiency.

[0062] Although the utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model.
