Description

Position control equipment of ceiling lamp

The present invention not only extends the irradiation time of light (green light) to greenhouses and vinyl houses or other indoor plants where horticultural crops are grown, but also increases the amount and quality by appropriately adjusting the amount of light to promote photosynthesis. In addition, the present invention relates to a lighting body position adjusting device which is installed at other barns or indoors to adjust light clarity and irradiation angle.

Artificial light has been widely used in the cultivation of horticultural crops as a precursor growing method and a supplementary growing method. As a cultivation to increase the production and quality by promoting the cultivation, it is widely used as a cultivation method of horticultural crops such as tomatoes and strawberries as well as flower crops such as chrysanthemum and roses.

Up to now, in the precursor and supplementary cultivation, a high-pressure sodium lamp, a fluorescent lamp, and an incandescent lamp have been mainly used. However, in recent years, LED lighting lamps have been spreading in accordance with the development of light emitting diodes (LEDs).

In particular, LED has many advantages as lighting for cultivation and precursor cultivation of horticultural crops, and it is easy to control light such as wavelength and amount of light, long life and good light efficiency.

In addition, the high pressure sodium lamps currently available in horticultural facilities are not suitable for the multi-stage type where the heat generation is large and the distance between the light source and the plant is small. The fluorescent lamps have the disadvantages of low red light component required for plant growth and uniform light irradiation. LEDs are energy efficient in that they can selectively examine the light emission wavelengths required by plants.

In addition, the LED can be irradiated with pulses that are not available in other light sources. Energy can be saved by using the pulsed light as a light source for gardening facilities.

As a result of botanists' research, the growth of plants is achieved through photosynthesis, and the wavelength range where photosynthesis is active is peaked at 450 nm and 660 nm bands of visible light. It has been used through the precursor growing method or the bowang cultivation method.

Conventionally, lighting lamps such as high pressure sodium lamps, fluorescent lamps, and incandescent lamps have been used, but as LED efficiency increases, LED usage is increasing.

In the related art, the plant chamber has been predominantly made. Republic of Korea Patent Application No. 2000-0006611 is a control system for plant growth for irradiating the optimal light according to the characteristics of the plant with the wavelength of the LED, Korea Utility Model Registration No. 20-0362989 In addition to the device for growing pigmented plants using LED US Patent 2008-0148630 also relates to a plant chamber targeted at the Enclose Plant for effective light irradiation and is not a technical study for direct application to horticultural facilities.

Korean patent 10-0879711 is an example of a technical research that applied a lighting device using LED directly to a gardening facility. This relates to a luminaire for promoting the photosynthesis by mixing and placing LEDs generating wavelengths of 640 nm to 675 nm and wavelengths of 425 nm to 455 nm.

However, for the photosynthesis of plants, there are light compensation points and light saturation points as important factors besides wavelength. For example, in the case of tomatoes, the light saturation point is 70,000 lx and the light compensation point is 3,000 lx, and the light intensity of the lamp must be between 70,000 lx and 3,000 x for photosynthesis. As the lamp illuminance is 25,000lx ~ 1,500lx, photosynthesis works. Strictly speaking, the photocompensation point and the light saturation point should be described in units of photosynthetic effective photon flux (PPFD), but this is explained here as there is a high positive correlation that high photosynthetic photon flux (PPFD) also increases. do.

In summary, for photosynthesis, the lamp emits roughness according to different light saturation points and light compensation points for different crops, and the 450nm or 660nm wavelength band must be irradiated to achieve the crop growth effect. There is a problem of only the reference to irradiation at the wavelength of 660 nm and the wavelength around 660 nm, and the method of illuminance emission according to the light compensation point and the light saturation point is not presented.

In addition, as described above, in order for the photosynthesis of crops, a relatively high light compensation point and a light saturation point are required. To this end, a lot of power is inevitable, and the high current applied to the LED has a high risk of shortening the lifetime of the LED.

Implication of illuminance is the intensity of light. Unlike other light sources, it is necessary to apply the current according to the light compensation point and light saturation point band to emit light at 450nm near wavelength and 660nm near wavelength. It is important to minimize heat generation as much as possible in the design of LED lighting fixtures because the LED junction temperature also increases as the current increases when the current is applied.

In addition, such lamps are fixedly installed using pipes on the upper floors of existing gardening facilities. Recently, the trend of gardening farmers is to increase the height of floors as much as possible. In the case of new horticulture facilities with high city or floor height and high ceiling, the irradiance is different, so there is a problem as an LED light fixture for precursor cultivation or supplementary cultivation.

The present invention is to solve the above problems, the object of the present invention is to adjust the height and angle of the illumination body to which the light is irradiated in the lighting body of the horticultural facility for precursor cultivation or supplementary cultivation (applicable to the plant) Illumination of vertical and horizontal planes and local lighting) to facilitate the photosynthesis of plants, thereby promoting the growth of plants and increasing production and quality. The present invention relates to a lighting body position adjusting device for adjusting an irradiation angle.

     Characteristic configuration of the present invention for achieving the above object is provided with a shade (110) having an open bottom, the inside of the shade is provided with a rotating body 120 for winding or unwinding the wire (W) and the rotating body One side of the first forward and reverse motor 130 to rotate the rotating body in the forward / reverse direction is installed by the lighting body lifting / lowering means 100, and the lower end of the wire is connected to the forward / reverse motor operation It receives and protects the heat dissipating plate 210 and the heat dissipating plate 210 and the heat dissipating plate 210 and any one of an incandescent lamp, a fluorescent lamp, a halogen bulb, a high-pressure sodium bulb, and a plurality of LEDs, and the array In the conventional lighting body position adjusting device consisting of a lighting body 200 consisting of a tube 230 which is disassembled and coupled from a heat sink and side caps 240 coupled to both ends of the heat sink,

 The lighting body 200 is installed on the bracket 310 formed on both side ends of the case 300 is installed so as to adjust the angle in the case 300 by the angle adjusting means 400, the angle adjusting means is the work The second cap motor 410 is connected to the side cap 240 and is installed, and the first and second motors are connected to the controller 500 and are installed at the angle and height of the lighting body 200 according to the signal of the controller. Is configured to be controlled.

And the fixed installation structure between the shaft 420 and the side cap 240 of the second stationary motor is one of the form of gear teeth, key coupling, triangular coupling of more than three, the rotating body 120 is a shaft Wire drums 121 are provided on both sides of the shaft to protect the wires.

The present invention provides an apparatus for adjusting the position of the light main body to appropriately control the illumination of different light compensation points and light saturation point bands for each plant grown indoors, thereby promoting the growth of plants and promoting the growth of plants according to promoting photosynthesis of plants. Not only can the quality be improved, but the maintenance of the lighting body is convenient, and the quantity of the lighting body in the horticultural facility can be reduced, so that it is possible to reduce the cost of facilities. There is an effect that can be used by properly adjusting the angle and angle.

Hereinafter, the lighting body position adjusting device of the present invention will be described in detail.

The present invention is close to the plant by adjusting the height of the top and bottom of the body and the local irradiation by adjusting the angle of the light body, and the illumination intensity can be adjusted by adjusting the height of the top and bottom of the light body can be optimized illumination.

However, the conventional lighting for the pre-optical cultivation cultivation can be said to be both fixed ceiling or post type. This is a problem that the optical compensation point (lx) and the optical compensation point (lx) required for the crop, which is a photosynthetic condition, cannot efficiently radiate due to the characteristics of the optical (LED) device.

In addition, illuminance (lux) is the intensity of the light source. Since the intensity of the light source is 1 / R square, the closer the distance between the lighting body and the object (crop) is, the greater the intensity of the light source is. This is to be improved.

 Specifically, the roughness formula is as follows.

E (lux) = F * U * N / A * D

E: roughness (lux)

F: luminous flux of light source (lm)

U: lighting rate

N: number of light sources

A: area [㎡]

D: Photosensitive Compensation Rate

Here, the illumination according to the distance between the light source and the object (crop) is as follows.

The luminous flux of both light sources is equal to 1000lm, N is 100, area is 50, and the photosensitivity is 2, and the distance between one light source and the object (crop) is 4m and the other light source is 0.5m. ), The illumination rate of a light source at a distance of 4 m is 340 lux, and a light source at a distance of 0.5 m is calculated at 630 lux.

Therefore, the light source can improve the lighting rate by irradiating the light near the object (crop). In particular, the illumination enhancement of 450 nm and 660 nm wavelengths is limited due to light (LED) characteristics. Therefore, we propose a method of irradiating close to objects (crops) from the ceiling of gardening facilities. This not only reduces the power costs of LED lighting sources, but also reduces the total number of lighting bodies required for gardening facilities.

To this end, unlike the conventional lighting body, the present invention is provided with a shade (110) is opened, the inside of the shade is provided with a rotating body 120 for winding or unwinding the wire (W) and one of the rotating body The first stationary motor 130 is installed on the side to rotate the rotating body in the forward / reverse direction, and is connected to the light main body lifting / lowering means 100 and the lower end of the wire to be lifted / lowered according to the operation of the stationary motor.
