Embodiment 1

[0038] This embodiment provides a light emitting device, such as figure 1 As shown, including light source, driver module and dimming control module; where,

[0039] The driving module is connected to the light source and a dimming control module, the dimming control module is used to output a control signal to the driving module, and the driving module is used to adjust the brightness of the light source according to the control signal.

[0040] The drive module of this embodiment adjusts the brightness of the light source according to the control signal, so as to realize the automatic timing of turning on and off the light source. At the same time, a natural brightness change transition process can be inserted between turning on and off the light to simulate dusk and dawn. When it illuminates the plants, The luminous device can fully simulate sunlight, thereby providing a suitable growth environment for plant growth and being beneficial to plant growth. The light-emitting d...

Embodiment 2

[0042] This embodiment provides a lighting device, including a light source, a driving module, and a dimming control module; wherein,

[0043] The driving module is connected to the light source and a dimming control module, the dimming control module is used to output a control signal to the driving module, and the driving module is used to adjust the brightness of the light source according to the control signal.

[0044] Preferably, the light source includes LED lights.

[0045] Specifically, the light source used in the light emitting device of the present invention is preferably an LED lamp.

[0046] Preferably, the dimming control module includes a first controller, and the first controller sequentially outputs h through pulse width modulation (Pulse Width Modulation, PMW) 1 The duration of the high-level control signal, h 2 The control signal of the long-term high level gradually transitioning to the low level, h 3 The duration of the low-level control signal, h 4 A...

Embodiment 3

[0061] This embodiment provides a light emitting device, which has a structure similar to that of the light emitting device in Embodiment 2. Such as Figure 5 As shown, the circuit of the lighting device mainly includes two parts, one part is the driving circuit of the light source LED lamp, which converts the 15V DC voltage input by the power supply into a constant DC current of 0.4A, and provides a constant DC current to the LED lamp. The other part is the timing dimming control circuit, which is connected to the enable control pin PMW of the drive circuit through the output pin PB2. According to the high level control signal output for 13 hours, the high level of 1 hour gradually turns to low level Transition control signal, 9-hour low-level control signal, and 1-hour low-level to high-level transition control signal control the working state of the drive circuit, thereby realizing timing and dimming control. Among them, the timing diagram of the output control signal of t...

Abstract

The invention provides a light emitting device and a method for regulating plant growth, which belong to the technical field of light emitting devices and can solve the problem that existing light sources cannot completely simulate natural light. In the light emitting device of the present invention, the driving module is connected to the light source and the dimming control module, the dimming control module outputs a control signal to the driving module, and the driving module adjusts the brightness of the light source according to the control signal. Further, the brightness of the light source is adjusted through the control signal to realize the automatic timing of turning on and off the light source. At the same time, a natural brightness change transition process is inserted in the middle of turning off the light to simulate dusk and dawn. When it illuminates plants, it can completely simulate sunlight. , to provide a suitable growth environment for plant growth, which is conducive to the growth of plants. The light-emitting device of the invention is suitable for lighting in various occasions, and is especially suitable for regulating the growth of plants.

Description

technical field [0001] The invention belongs to the technical field of light emitting devices, and in particular relates to a light emitting device and a method for regulating plant growth. Background technique [0002] In recent years, LED light sources have been widely used as a new generation of green and energy-saving light sources. Among them, the LED light source can be used as a light source for plant growth due to its small size and energy-saving characteristics. [0003] The inventors have found that there are at least the following problems in the prior art: most light sources of this type on the market can only provide light, and cannot automatically realize the control of turning on and off the lights at regular intervals, and the LED light sources on the market currently do not have lighting to extinguishing, and extinguishing. The transition process of brightness change from lamp to lighting does not match the actual natural lighting and cannot completely simu...
