Description

Bulb type LED lamp {Bulb type LED lamp}

The present invention relates to an LED lamp made of a bulb type, and more particularly to a versatile bulb-type LED lamp that irradiates light for plant growth and general lighting and light for pest control.

In general, a discharge lamp such as a fluorescent lamp, an incandescent lamp or a halogen lamp is used as an indoor light source for a home or an office.

Such a discharge lamp has a large energy consumption due to a high driving voltage and an increase in power, and discharges discharge gas such as mercury, which is harmful to a human body or the environment when disposed, and thus causes environmental pollution and is impossible to recycle.

Accordingly, the necessity of research and development of a new luminaire that can replace a luminaire such as a fluorescent lamp currently used is emerging.

Recently, as a durable light bulb that can be used for a long time while lowering power consumption and increasing illumination, many lighting fixtures using LED as a light source have been proposed.

LED (light emitting diode) is a light source using the light emitting phenomenon generated when voltage is applied to the semiconductor, and the brightness has been improved enough to be used for lighting due to the development of technology over the last several years. Because of its length, its use is spreading for general light bulbs.

However, in the case of a light source employing an LED lamp to replace the existing incandescent lamp, the light is irradiated only in the front direction of the LED lamp due to the straightness of the light, and thus, unlike the conventional incandescent light bulb, the light is emitted behind the LED lamp. As a result, users tend to be reluctant to use LED lamps as a replacement for incandescent bulbs.

On the other hand, chloroplasts contained in plants and phytoplankton are called carbon assimilation by synthesizing carbohydrates such as starch from carbon dioxide and water with the power of sunlight.

This carbon assimilation is the source of nutrition in the ecosystem and the supply of oxygen to the air and water, and the process by which green plants and other organisms convert light energy into chemical energy is called photosynthesis. And because of carbon compounds on the ground, both can be derived from photosynthesis.

And, in order to achieve a more efficient photosynthesis of plants can be achieved through a method of effectively supplying a light source belonging to the wavelength range of a specific region.

Therefore, the present invention is easy to use and handle, and can be effectively irradiated around the lamps, such as the front as well as the rear, and the object of the present invention is a bulb type LED lamp that can promote plant growth using an LED lamp. .

In particular, where there are plants and vegetables, such as plastic houses, or botanical gardens or plantations, where there is a need for light to grow at night, at night, insects gather after the light, so they chase them around the plants. There is a need for means.

The purpose is to provide a versatile bulb-type LED lamp that can effectively chase pests around the plant.

In order to achieve the above object, the bulb-type LED lamp provided in the present invention is made of a bulb type including a base that can be connected to a general bulb socket, and a spherical transparent or translucent cover. The plant growth LED module at the bottom and the pest control LED module at the top are arranged step by step, in which a plurality of mounted LEDs are arranged, which can promote plant growth and effectively chase pests. .

Here, the plant growth LED module is preferably configured to include a disk-shaped substrate having a plurality of LEDs arranged horizontally in the center of the cover, and a support coupled to the base side while extending integrally from the rear surface of the substrate. Do.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view of a bulb-type LED lamp according to an embodiment of the present invention, Figure 2 is an exploded cross-sectional view of the bulb-type LED lamp according to an embodiment of the present invention, Figure 3 is according to an embodiment of the present invention The combined cross section of the bulb type LED lamp is shown, respectively.

As shown in Figures 1 to 3, the bulb-type LED lamp is a lamp made of a form that can be used as it is connected to a general socket, a form that can simultaneously irradiate the light necessary for plant growth and the light required to combat pests. Is made of.

To this end, the bulb-type LED lamp is a base 10 that can be connected to the normal bulb socket, that is, the base 10 of the form that can be screwed in or removed by screwing into the socket, and integral with the base 10 And a cover 11 made of sphere-shaped transparent or translucent. At this time, the cover 11 is separated into two upper and lower cut the middle portion.

Accordingly, the bulb-type LED lamp can be used as it is connected to the socket, such as the existing incandescent bulb, and can be used to illuminate the entire area of the lamp, so that the light utilization efficiency can be increased.

In particular, the bulb-shaped LED lamp comprises two LED modules, namely the LED module 13 for plant growth and the LED module 14 for combating pests.

The plant growth LED module 13 and the pest control LED module 14 are installed in the cover 11 and electrically connected to the base 10 side, respectively, at a predetermined interval from each other in the lower and upper portions. Positioned by using their own functional LED (12) to irradiate the light necessary for plant growth and pest control.

In this case, the plant growth LED module 13 may be replaced with an LED for irradiating light for general lighting instead of the LED 12a for irradiating light for plant growth.

These LED modules have a form in which a plurality of LEDs (12a, 12b) mounted in an electrode circuit on the substrate is arranged, a large area plant growth LED module 13 at the bottom, a relatively narrow area at the top The pest control LED module 14 is structured in stages, respectively.

In the case of the LED module 13 for plant growth, plants can be cultivated in a closed space without using sunlight by using the LED 12a, and red light, blue light, or a mixture of red and blue light according to the characteristics of the crops. By adjusting the proportions and exposing them to plants, they promote growth.

For example, the most suitable wavelengths for plant photosynthesis and leaf formation are red and blue wavelengths, so LEDs having a wavelength for promoting photosynthesis (red light wavelengths of 640 to 690 nm) and wavelengths for promoting leaf formation (blue light) By appropriately arranging LEDs having a wavelength of 420 to 470 nm, plant growth can be effectively promoted.

In addition, in the pest control LED module 14, pests such as mosquitoes and moths can be attracted and eliminated in the ultraviolet (367 nm) and blue light (403 nm, 461 nm) regions of the LED 12b. Since the properties attracted to the light is different, it is preferable to include LEDs 12b in various wavelength ranges and to select appropriately according to the use place.

That is, since the LED 12b of the pest control LED module 14 is excellent in insect pest attraction effect and suppression and generation suppression effect of pests, the LED lamps have a customized LED lamp for each insect pest avoidance and generation suppression wavelength. It is preferable to use.

The plant growth LED module 13 for promoting plant growth includes a disc-shaped substrate 15a in which a plurality of LEDs 12a are arranged, and a support 16a for supporting the substrate 15a.

The disk-shaped substrate 15a is installed in a shape arranged horizontally in the center of the cover 11, that is, the sphere is divided into half hemispheres while crossing the center of the cover 11 having a spherical shape. In this case, the LEDs 12a are disposed in a shape distributed over the entire area of the substrate 15a and electrically connected to a circuit on the substrate.

In addition, a light sensor 18 is installed at the center of the substrate 15a to detect light around the lamp. Accordingly, by detecting the light sensor 18, the lamp may be turned on only at night without light. It becomes possible.

Here, the light sensor 18 may be applied to the known sensors on the market.

The support 16a is disposed on the rear side of the substrate 15a and coupled to the base 10 side, and serves to support the original plate 15a to which the LED 12a belongs.

In particular, the circumferential surface of the support 16a is made of a curved surface extending outward from the upper end (the side with the base) toward the lower end, and the curved surface is made of the coated reflective layer 17.

Accordingly, the light irradiated from the pest control LED module 14 can be easily diffused while being reflected by the reflective layer 17 of the support 16a, even with a small number of LEDs 12b. Sufficient dose can be obtained.

Here, the deposition material constituting the reflective layer may be applied to a conventional material used for the reflective surface of the general lamps.

The pest control LED module 14 includes a ring-shaped substrate 15b in which a plurality of LEDs 12b are arranged, and a support 16b for supporting the substrate 15b.

The ring-shaped substrate 15b is disposed side by side while being spaced apart a predetermined distance from the substrate 15a of the LED module 13 for plant growth in parallel and at the same time disposed along the circumference of the central support 16a, At this time, the LEDs 12b are disposed in a shape concentrically distributed along the top surface of the substrate 15b and are electrically connected to a circuit on the substrate.

The support 16b is disposed on the rear side of the substrate 15b and connected to the base 10 side, and serves to support the original plate 15b to which the LED 12b belongs.

Here, the ring-shaped substrate 15b has a relatively small diameter compared to the substrate 15a of the plant growth LED module 13, and thus is irradiated from the LED 12a on the substrate 15b. The light is naturally reflected toward the reflective layer 17 of the support 16a which forms the rear surface of the substrate 15a, so that light can spread widely around.

The support 16b is provided with a heat dissipation groove 19 for dissipating heat in a form that is arranged at a predetermined interval along the outer circumferential surface and is cut in the longitudinal direction, and thus, by the cover 11 The support 16b that is not enclosed and exposed is able to effectively discharge heat generated from the LED through contact with air using the heat dissipation groove 19.

Therefore, the base 10 of the bulb-type LED lamp configured as described above is made of a form that can be inserted or removed by screwing, can be used as it is connected to a socket such as a conventional incandescent bulb, and made of a spherical shape This has the advantage that efficient illumination is possible throughout the lamp's surroundings.

In particular, the bulb-type LED lamp is made of a combination of the pest control LED module 14 and the plant growth LED module 13 disposed at a predetermined interval up and down, plant growth as well as pest control two functions Has the characteristics to exert.

That is, in the case of the LED module 13 for plant growth, plant growth is appropriately arranged by arranging an LED having a red light wavelength of 640 to 690 nm that promotes photosynthesis and an LED having a blue light wavelength of 420 to 470 nm that promotes leaf formation. It can be promoted effectively.

In addition, in the case of the LED module 14 for exterminating insect pests, pests such as mosquitoes and moths can be effectively combated by appropriately arranging ultraviolet rays having a wavelength of 367 nm and blue light having a wavelength of 403 nm and 461 nm.

Figure 4 shows a cross-sectional view of a bulb-type LED lamp according to another embodiment of the present invention.

Here, the shape of the support 16a and the position of the LED module 14 for combating pests are modified.

That is, the support 16a is disposed on the rear side of the substrate 15a and coupled to the base 10 side, and serves to support the original plate 15a to which the LED 12a belongs. .

Thus, the support 16a is in the shape of the entire shape, wherein the circumferential surface of the upper coupling surface is made of an inverted triangular curved surface is reduced inwards toward the lower end from the top (the side with the base), the curved surface at this time The reflective layer 17 is coated. And the pest control LED module 14 is installed on the lower surface of the support (16a).

Accordingly, the light irradiated from the LED module 14 for exterminating insects is reflected by the reflective layer 17 of the support 16a, so that the surroundings, in particular, the LED is shining upward, so that it can be more easily diffused. As a result, a sufficient irradiation amount can be ensured even with a small number of LEDs 12b.

On the other hand, in each of the above embodiments it is possible to increase the diffusion of light by forming a diffusion lens on the lower cover.

5 is a cross-sectional view of a bulb-type LED lamp according to another embodiment of the present invention, Figure 6 is a bottom configuration of Figure 5.

As shown, the spherical bottom side of the lower cover 11 is formed in a flat portion, and the diffused lens 20 made of a convex lens is formed in each of the flat portions to correspond to the LEDs 12a.

Accordingly, the light of the LED module 13 for plant growth is more brightly diffused to help the growth of the plant.

In the present invention as described above, a means for separating the light of the LED module 13 for plant growth and the LED module 14 for combating pests is required.

Accordingly, the reflection shade 21 may be further provided at the coupling portion side of the cover 11 divided into upper and lower portions.

The reflection shade 21 may be formed in the middle of the cover 11, the upper and lower forms, but preferably it is better to form a binding from the outside while the bulb type LED lamp can be used independently.

That is, the center portion is formed with a coupling portion that is bound to the outer periphery of the cover and the outer side has a thin disk-shaped wing portion, when the reflection shade 21 is pushed and pressed from the upper side or the lower side of the cover 11 when the reflection shade ( The inner circumferential edge of 21 is inserted into the outer circumferential edge of the cover 11 while being fitted.

Accordingly, the bulb-type LED lamp is generally used independently without the reflection shade 21 to promote convenience, and in addition, the insect light is separated from the plant growth light and the pest control light to increase the effectiveness of the pest control. It becomes possible.
