Problems solved by technology

The Chinese invention patent with the publication number CN106413199B solves the problem of energy consumption loss of plant lamps, but it needs to manually set the value and then make a comprehensive comparison to get the optimal light intensity and time; the Chinese invention patent with the publication number CN104076846B, through supplement The light controller solves the problem of the intensity of red and blue light, but too many interfaces are easy to be poorly connected in harsh environments, resulting in failure or damage to the lamps, and the laser plant lights are often affected by the severity of smog and the sun during use. Light intensity and the influence of some human factors
Considering the two key points of plant photosynthesis, that is, the light compensation point and the light saturation point, when it reaches above the light compensation point, as the light intensity increases, the photosynthetic rate also increases correspondingly. When a certain light intensity is reached, the photosynthetic rate The speed will no longer increase with the increase of light intensity, that is, the light saturation phenomenon has been reached. At this time, if the external light intensity is greater than the light saturation point of the plant, the plant will not absorb more light, and light will be wasted.

Embodiment 1

[0029] Such as Figure 1-4 As shown, a laser plant lamp that automatically adjusts the laser intensity is used for plant growth lighting, and can automatically adjust the laser intensity with the intensity of external light, including: a bracket L for installing the laser plant lamp (laser plant lamp group 10), a control Unit, photosensitive device, lighting module 1, power module 2, power supply fixing plate 3, heat dissipation device 4, housing 5, heat dissipation air outlet 6, light sensor 7, heat dissipation hole 8, wire 9, laser plant lamp group 10, triangular structure 11, Leg 12, lock 13, rotary turntable 14, threaded knob 15 and radiator 16, the bracket L is used to support the whole laser plant lamp, the power module 2 is a constant current voltage, and is installed on the power supply fixing plate 3 by dispensing silica gel , the lighting module 1 includes a circuit board and a laser plant light group 10, the laser plant light group 10 is packaged on the circuit boar...

Embodiment 2

[0032] The combined irradiation of 4 red laser lights and 1 blue laser light in Example 1 is replaced by the combined irradiation of 6 red laser lights and 1 blue laser light, and the connection mode and measurement environment remain unchanged. Due to the increase of the number of laser lamps, the power of the laser plant lamp will increase, and the heat generated will also increase. Therefore, in order to reduce the temperature and ensure the reliability and sensitivity of use, heat dissipation holes 8 are provided on each side of the casing 5 to improve Heat dissipation effect of laser plant lights. Under the irradiation of this combination, the plants grow slowly, and the color of the leaves is obviously dim. At this time, the measured spectral range is between 500nm-620nm, and it is found that the data is neither between 400nm-520nm (blue) nor 610nm-720nm (red), the light sensor 7 converts the signal into a voltage signal and sends it to the control unit, and the control ...

[0035] Re-change the matching ratio of red and blue laser lights to 8:1, and improve the cooling device 4, such as figure 2 As shown, in addition to being provided with a radiator 16 in the heat dissipation device 4, a cooling fan is also added. The cooling fan is installed on the end face of the casing 5, and its wind direction blows to the radiator 16 and the overall fixed plate, which can not only take away the heat of the radiator 16 The heat can also cool down the components on the overall fixed plate to ensure the normal use of the laser plant lamp and improve its life. Under the irradiation with a ratio of red and blue of 8:1, the plants grow better, the branches and roots are stronger, and the flowering and fruiting are faster. At this time, the main performance is red light, that is, the spectral range is 610nm-720nm, which is suitable for plants. The growth and development requirements of the plant, especially the effect on the flowering and fruiting stage of the pl...

Abstract

The invention discloses a laser plant lamp capable of automatically adjusting laser intensity. The laser plant lamp comprises a support L, a power module, a lighting module, a heat radiating device, alight sensing device, a control unit, a power source fixing plate, a casing and an integral fixing plate. The power module is arranged on the power source fixing plate. The lighting module is electrically connected with the heat radiating device. The heat radiating device comprises a heat radiator and a cooling fan. Wind of the cooling fan is blown to the heat radiator and the integral fixing plate, so that the heat of the heat radiator is blown away, elements on the integral fixing plate are cooled down, and the safety and reliability of the laser plant lamp are improved. The light sensing device is electrically connected with the control unit, an illumination sensor in the light sensing device converts a detected external illumination intensity signal into a voltage value signal and sends the voltage value signal to the control unit, and the control unit checks and resets data, so that the laser intensity of the laser plant lamp is changed. Each element is detachably fixed to the integral fixing plate, and the elements can be directly replaced in case of damage.

Description

technical field [0001] The invention belongs to the field of plant lighting, in particular to a laser plant lamp which can automatically adjust the intensity of laser light. Background technique [0002] The light environment is one of the indispensable physical factors for plant growth and development. In some areas with severe haze or insufficient light, sufficient light is especially important. The solar spectrum is a continuous spectrum with a wavelength range of 400nm-760nm, but the most significant effect on photosynthesis is only the blue light of 400nm-520nm and the red light of 610nm-720nm. In some environments, a combination of red and blue light in different proportions is even required. Improve photosynthesis of plants. In order to meet the needs of plants in various environments for good photosynthesis, various plant growth lights have emerged as the times require. The common plant lights on the market now generally include fluorescent lamps, sodium lamps and ...
