Example 1
Referring to fig. 1, the present embodiment provides a light emitting module 100 for lighting equipment, indicator lights, display screens, and the like.
The light emitting module 100 includes a light emitting module 110 and a voltage control module 120, wherein the light emitting module is a voltage control type light emitting device. The voltage control module 120 is electrically connected to the light emitting module 110, and the voltage control module 120 is used for controlling the working voltage of the light emitting module 110, so as to control the light-emitting module 100 to be turned on or turned off.
It can be understood that the number of the light emitting modules 110 in the light emitting module 100 may be more, and the light emitting modules 110 are arranged in parallel, and the light emitting modules 110 are electrically connected to the voltage control module 120 of the light emitting module 100.
The light emitting module 100 includes at least two light emitting units, and the light emitting voltage ranges of at least two light emitting units are not completely the same. In order to more clearly describe the technical solution of the embodiment of the present invention, the following description takes the light emitting module 100 as an example.
The light emitting module 100 includes a light emitting module 110 and a voltage control module 120, the light emitting module 100 includes a first light emitting unit 111 and a second light emitting unit 112, and the first light emitting unit 111 and the second light emitting unit 112 are connected in parallel and electrically connected to the voltage control module 120.
In this embodiment, the first light emitting unit 111 and the second light emitting unit 112 are both an LED chip, and it can be understood that the first light emitting unit 111 and the second light emitting unit 112 may also be LED diodes or other voltage control type light emitting elements, which can be flexibly adjusted according to actual production design requirements, and is not limited thereto.
Referring to fig. 1 and fig. 2, the light emitting voltage ranges of the first light emitting unit 111 and the second light emitting unit 112 are not completely the same, in the embodiment, the span value of the light emitting voltage range of the first light emitting unit 111 (i.e., the difference between V2 and V1) is greater than the span value of the light emitting voltage range of the second light emitting unit 112 (i.e., the difference between V4 and V3), and the upper limit V2 of the light emitting voltage range of the first light emitting unit 111 is smaller than the lower limit V3 of the light emitting voltage range of the second light emitting unit 112.
The voltage control module 120 is capable of regulating the operating voltage within the range of V1-V4, and may also regulate the operating voltage to less than V1, and may also regulate the operating voltage to greater than V4.
Since the first light emitting unit 111 and the second light emitting unit 112 are connected in parallel, the voltages of the two are the same. If the operating voltage is lower than the lower limit V1 of the light emitting voltage range of the first light emitting unit 111, the first light emitting unit 111 and the second light emitting unit 112 are both in the off state, and the light emitting module 110 is in the off state.
When the operating voltages of the first light emitting unit 111 and the second light emitting unit 112 are adjusted by the voltage control module 120, the operating voltages are gradually increased to reach the lower limit V1 of the light emitting voltage range of the first light emitting unit 111, but not reach the lower limit V3 of the light emitting voltage range of the second light emitting unit 112, so that the first light emitting unit 111 is lit, the second light emitting unit 112 is not lit, and the light emitting module 110 is in a lit state.
When the voltage control module 120 controls the operating voltage to vary within the light emitting voltage range of the first light emitting unit 111 (i.e., V1-V2), the first light emitting unit 111 is in the light emitting state, and the second light emitting unit 112 is in the non-light emitting state, and at this stage, the light emitting module 110 is in the light-up state.
The voltage control module 120 continues to control the operating voltage to increase, and when the operating voltage just exceeds the upper limit V2 of the light emitting voltage range of the first light emitting unit 111, the first light emitting unit 111 is turned off, and at this time, both the first light emitting unit 111 and the second light emitting unit 112 are in the off state, and the light emitting module 110 is in the off state.
The voltage control module 120 is used to control the operating voltage to increase continuously until the operating voltage reaches the lower limit value V3 of the light emitting voltage range of the second light emitting unit 112, the second light emitting unit 112 lights up, the first light emitting unit 111 is in the off state, and the light emitting module 110 is in the on state.
When the voltage control module 120 controls the operating voltage to vary within the light emitting voltage range (i.e., V3-V4) of the second light emitting unit 112, the second light emitting unit 112 is in the light emitting state, and the first light emitting unit 111 is in the non-light emitting state, at which stage the light emitting module 110 is in the light-up state.
The voltage control module 120 is used to control the operating voltage to continue increasing until the operating voltage exceeds the upper limit value V4 of the light emitting voltage range of the second light emitting unit 112, the second light emitting unit 112 is turned off, the first light emitting unit 111 is also in a turned-off state, and the light emitting module 110 is turned off.
Thus, it can be seen that by controlling the operating voltage of the light emitting module 110 by the voltage control module 120, the first light emitting unit 111 is controlled to be lit up alone, the first light emitting unit 111 and the second light emitting unit 112 are controlled to be lit up together, the second light emitting unit 112 is controlled to be lit up alone, and the first light emitting unit 111 and the second light emitting unit 112 are controlled to be lit off together. It should be noted that, in three cases, the first light-emitting unit 111 is individually turned on, the second light-emitting unit 112 is individually turned on, and the first light-emitting unit 111 and the second light-emitting unit 112 are both turned on together, the overall brightness of the light-emitting module 110 is different, that is, the voltage control module 120 is used to control the operating voltage of the light-emitting module 110, so that the first light-emitting unit 111 and the second light-emitting unit 112 can be switched between the off states of the on states, thereby achieving the purpose of controlling the overall brightness of the light-emitting module 110.
The voltage control module 120 is used to control the light emitting mode of the light emitting module 110, so that the traditional limitation of using a single light emitting element for light emission is broken, and the brightness adjusting range of the single light emitting element is not limited. The first light emitting unit 111 has a certain brightness adjusting range, the second light emitting unit 112 has a certain brightness adjusting range, the light emitting module 110 has the brightness adjusting range of the first light emitting unit 111 and the brightness adjusting range of the second light emitting unit 112 at the same time, the brightness adjusting range of the light emitting module 110 is effectively expanded, so that the whole light emitting effect and the adjustable brightness range of the light emitting module 100 are obviously improved, the brightness adjustment in a wider range can be realized only by adjusting the working voltage by the voltage control module 120, and the method is very convenient and practical.
It is understood that, in other embodiments of the present invention, the span value of the light emitting voltage range of the first light emitting unit 111 (i.e., the difference between V2 and V1) may also be less than or equal to the span value of the light emitting voltage range of the second light emitting unit 112 (i.e., the difference between V4 and V3). It should be noted that, when the span value of the light emitting voltage range of the first light emitting unit 111 (i.e., the difference between V2 and V1) is equal to the span value of the light emitting voltage range of the second light emitting unit 112 (i.e., the difference between V4 and V3), the light emitting voltage ranges cannot be overlapped, i.e., V1 and V3, and V2 and V4 cannot be the same, otherwise the luminance adjustment range cannot be widened.
Referring to fig. 1 and fig. 3, in a first modification of the present embodiment, the upper limit V2 of the light-emitting voltage range of the first light-emitting unit 111 is equal to the lower limit V3 of the light-emitting voltage range of the second light-emitting unit 112. At this time, in the process of adjusting the operating voltage of the light emitting module 110 by the voltage control module 120, in both cases where the operating voltage is lower than the lower limit value V1 of the light emitting voltage range of the first light emitting unit 111 and the operating voltage is higher than the upper limit value V4 of the light emitting voltage range of the second light emitting unit 112, both the first light emitting unit 111 and the second light emitting unit 112 are in the off state, and the light emitting module 110 is in the off state. When the operating voltage is in another range, that is, the operating voltage is greater than or equal to the lower limit V1 of the light emitting voltage range of the first light emitting unit 111 and is less than or equal to the upper limit V4 of the light emitting voltage range of the second light emitting unit 112, at least one of the first light emitting unit 111 and the second light emitting unit 112 is in a light state, and the light emitting module 110 is always in a light state. Since the light emitting voltage range of the first light emitting unit 111 and the light emitting voltage range of the second light emitting unit 112 are overlapped at V2 (i.e., V3), and the light emitting voltage ranges of the two are partially overlapped, when the operating voltage reaches the upper limit value V2 of the light emitting voltage range of the first light emitting unit 111, i.e., the lower limit value V3 of the light emitting voltage range of the second light emitting unit 112, the first light emitting unit 111 and the second light emitting unit 112 will be simultaneously lighted, and the brightness of the light emitting module 110 is maximum at this time. In this way, the light emitting module 110 has a light emitting mode in which the first light emitting unit 111 and the second light emitting unit 112 are simultaneously turned on, so that the light emitting module 110 has a light emitting form with higher brightness, the light emitting brightness of the light emitting module 100 as a whole is wider in adjustment range, and the light emitting form is more various.
In this variation, the voltage control module 120 is capable of regulating the operating voltage within the range of V1-V4, and may also regulate the operating voltage to be less than V1, and may also regulate the operating voltage to be greater than V4.
Referring to fig. 1 and fig. 4, in a second variation of the present embodiment, the upper limit V2 of the light emitting voltage range of the first light emitting unit 111 is greater than the lower limit V3 of the light emitting voltage range of the second light emitting unit 112, and the upper limit V2 of the light emitting voltage range of the first light emitting unit 111 is smaller than the upper limit V4 of the light emitting voltage range of the second light emitting unit 112, at this time, the lower limit V1 of the light emitting voltage range of the first light emitting unit 111 is smaller than the lower limit V3 of the light emitting voltage range of the second light emitting unit 112. The light emitting voltage range of the first light emitting unit 111 and the light emitting voltage range of the second light emitting unit 112 partially overlap (i.e., V3-V2), that is, when the operating voltage is in the overlapping portion of the light emitting voltage ranges, the first light emitting unit 111 and the second light emitting unit 112 are in the light-up state at the same time; when the operating voltage is within the light emitting voltage range of the first light emitting unit 111 but not at the overlapping part of the light emitting voltage ranges, only the first light emitting unit 111 is in the light-up state; when the operating voltage is within the light emitting voltage range of the second light emitting unit 112 but not at the overlapping portion of the light emitting voltage ranges, only the second light emitting unit 112 is in the light-up state. Compared with the first modification, the voltage range of the first light-emitting unit 111 and the second light-emitting unit 112 which are simultaneously lighted is widened, so that the voltage control module 120 can more conveniently and more accurately control the first light-emitting unit 111 and the second light-emitting unit 112 to be simultaneously lighted, the light-emitting module 110 is stably in the state of the maximum light-emitting brightness, and the light-emitting module 110 is prevented from being overlooked and overlooked due to voltage fluctuation.
In this variation, the voltage control module 120 is capable of regulating the operating voltage within the range of V1-V4, and may also regulate the operating voltage to be less than V1, and may also regulate the operating voltage to be greater than V4.
In order to enable the luminance of the light emitting module 110 to be more conveniently adjusted and to make the luminance of the light emitting module 110 sensitively changed, the ratio of the span value of the light emitting voltage ranges of both the first and second light emitting units 111 and 112 to the span value of the overlapped portion is greater than or equal to 2, and it is understood that the ratio of the span value of the light emitting voltage ranges of both the first and second light emitting units 111 and 112 to the span value of the overlapped portion may also be 2.5, 3, 3.5, 4, 5, etc., and is not limited thereto. In the present modification, the ratio of the span value of the emission voltage range of the first light-emitting unit 111 to the span value of the overlap portion is equal to 3, and the ratio of the span value of the emission voltage range of the second light-emitting unit 112 to the span value of the overlap portion is equal to 2.
Referring to fig. 1 and 5, in a third variation of the present embodiment, the upper limit V2 of the light-emitting voltage range of the first light-emitting unit 111 is equal to the upper limit V4 of the light-emitting voltage range of the second light-emitting unit 112, and at this time, the lower limit V1 of the light-emitting voltage range of the first light-emitting unit 111 is smaller than the lower limit V2 of the light-emitting voltage range of the second light-emitting unit 112. The light emitting voltage range of the second light emitting unit 112 completely falls within the light emitting voltage range of the first light emitting unit 111. When the operating voltage is within the light emitting voltage range of the second light emitting unit 112, both the first light emitting unit 111 and the second light emitting unit 112 are simultaneously lighted. When the operating voltage is within the light emitting voltage range of the first light emitting unit 111 and is not within the light emitting voltage range of the second light emitting unit 112, only the first light emitting unit 111 lights up. Compared with the second modification, the voltage range when the first light-emitting unit 111 and the second light-emitting unit 112 are simultaneously turned on is further expanded, the light-emitting module 110 has two light-emitting modes, namely, the first light-emitting unit 111 emits light alone, and the first light-emitting unit 111 and the second light-emitting unit 112 emit light simultaneously, and the switching between the light-emitting modes is smoother, continuous and more convenient.
In this variation, the voltage control module 120 is capable of regulating the operating voltage within the range of V1-V4, and may also regulate the operating voltage to be less than V1, and may also regulate the operating voltage to be greater than V4.
Referring to fig. 1 and fig. 6, in a fourth modification of the present embodiment, the upper limit V2 of the light emitting voltage range of the first light emitting unit 111 is greater than the upper limit V4 of the light emitting voltage range of the second light emitting unit 112, and the lower limit V1 of the light emitting voltage range of the first light emitting unit 111 is less than the lower limit V3 of the light emitting voltage range of the second light emitting unit 112. At this time, the light emitting voltage range of the second light emitting unit 112 completely falls within the light emitting voltage range of the first light emitting unit 111, except that when the operating voltage is lower than the light emitting voltage range of the second light emitting unit 112, and when the operating voltage is higher than the light emitting voltage range of the second light emitting unit 112, there are cases where light is emitted by the first light emitting unit 111 alone. Compared with the third modification, when the operating voltage is controlled to leave the light-emitting voltage range of the second light-emitting unit 112, whether the operating voltage is reduced or increased, the light-emitting module 110 is switched to the mode in which the first light-emitting unit 111 emits light alone, and the mode in which the first light-emitting unit 111 emits light alone can be used as a transition mode when the mode in which the first light-emitting unit 111 and the second light-emitting unit 112 emit light together is exited, so that the intensity of brightness change of the light-emitting module 110 is reduced, and discomfort of a user is avoided.
In this variation, the voltage control module 120 is capable of regulating the operating voltage within the range of V1-V2, and may also regulate the operating voltage to be less than V1, and may also regulate the operating voltage to be greater than V2.
Referring to fig. 1 and 7, in a fifth modification of the present embodiment, the upper limit V2 of the light emitting voltage range of the first light emitting unit 111 is greater than the upper limit V4 of the light emitting voltage range of the second light emitting unit 112, and the lower limit V1 of the light emitting voltage range of the first light emitting unit 111 is equal to the lower limit V3 of the light emitting voltage range of the second light emitting unit 112. At this time, the light emission voltage range of the second light emitting unit 112 also falls entirely within the light emission voltage range of the first light emitting unit 111, similarly to the case of the third modification of the present embodiment, except that the voltage value of the voltage interval lit up by the first light emitting unit 111 alone is larger than the voltage value of the light emission voltage ranges of the two light emitting units.
