[0001] The present invention relates to a LED apparatus for raising seeding,

More particularly, the present invention relates to an LED seedlings device, in which an external loss of a light source is blocked without using a reflector, the light source concentration ratio is improved, the photon flux density can be finely adjusted and on / , and a LED seedlings device capable of increasing the installation space of the LED light source to increase the maximum photon flux density per wavelength band to at least three times higher than the conventional one.

Recently, the demand for vegetable seedlings has been increasing due to the increase in the area of horticultural facilities. Among them, demand for grafted seedlings with grafting and stiffness is increasing each year, and favorable quality and uniform seedlings are preferred. It is a trend that is gradually changing from a method to a method of nurturing process which is done in a specialized nursery with facilities and technology.

In order to produce uniform grafted seedlings, grafting and propagation techniques are required along with the production of high-quality grafts and logs, but most of them are produced in tunnels that block natural light from nurseries in the process. Because morphogenesis depends on the external climate, it is difficult to produce high quality grafted seedlings.

The light sources most commonly used in plant cultivation are fluorescent lamps, metal halide lamps, and incandescent lamps. These light sources are developed mainly as lighting devices for humans, and are suitable for plant cultivation having photoreceptors different from human .

In the conventional seedling growing apparatus disclosed in Patent Registration No. 10-142264, a light emitting layer made of a compositional formula (AlXGa1-X) YIn1-YP (0? X? 0.1, 0 <Y? 1) having a peak emission wavelength of 655 nm or more and 675 nm or less And a second light emitting diode having a light emitting layer of a composition formula GaXIn1-XN (0? X? 1) having a peak emission wavelength of 420 nm or more and 470 nm or less, wherein the first light emitting diode has a pn junction type light emitting portion, Wherein the first light emitting diode and at least one second light emitting diode are mounted in the same package, wherein the first light emitting diode and the second light emitting diode are mounted on the multi-color light emitting diode lamp A technique in which the photometric quantities R [占 퐉 ol 占--1] of the first light emitting diodes and the photometric quantities B [占 퐉 ol 占 퐏-1] of the at least one second light emitting diodes satisfy the relationship of R> It has been registered.

In addition, in the patent registration No. 10-1397193, a light source for irradiating light toward a shelf holding a seedling tray on which a grafted seedlings are mounted and a seedling tray accommodated in a shelf, A plurality of first LED light sources for emitting light in a 670 nm wavelength band and a plurality of second LED light sources for emitting light in a 430 to 460 nm wavelength band are combined to form mixed light, The controller may further include a controller for controlling the photosynthetic photon flux density (PPFD) of the light source, wherein the photosynthetic photon flux density (PPFD) of the first LED light source is in the range of 1.5 to 2: To 12 μmol / m 2 s, and the photosynthetic photon flux density (PPFD) of the second LED light source is controlled to 5 to 6 μmol / m 2 s.

First, the red wavelength light source and the blue wavelength light source are confined to a predetermined ratio or a limited number, and are limited to the plant cultivation method by independent light sources according to each wavelength band. Thus, , It is necessary to provide dedicated seedling units according to the characteristics of the crops. In particular, there is a problem that the limitation of the light source control can not reflect the know-how accumulated in the cultivation farmers actively.

Second, in order to maintain a uniform photon flux density throughout the seedling pot, a bar-shaped light source package is disposed in a spaced apart position. In this case, each of the light source packages has a central region where the light sources are overlapped with each other, Since the light sources in the both side non-overlapping irradiation areas are all lost out of the seedlings, the energy efficiency is drastically lowered. As a result, a separate condensing member There is a troublesome problem that the user must additionally install the device.

Third, since the light source package is formed in a bar shape and the LED light sources according to the wavelength ranges are arranged in series, it is difficult to secure the installation space of the LED light source, so that there is a limit in increasing the density of the photons by wavelength band. It is necessary to control the density of the photon quantum by the additional installation method.
