It relates to a light emitting unit for preventing pests and a method of manufacturing the same.

In general, as the climate warms in summer, many types of pests such as flies and mosquitoes inhabit.

These pests are actively active in the outdoors, such as mountains or rivers, where people are rare, depending on the surrounding conditions, and can be easily found in houses where people live and in brightly lit commercial areas, so that the pests come into direct contact with the skin during activities. As a result, drugs such as fumigants, spraying agents and mosquito repellents are used as a means to prevent contact with pests during outdoor activities such as fishing and mountaineering, or mosquito nets are installed in some cases.

However, since this method directly applies a chemical agent to the skin, a person with allergies to the skin not only suffers a rejection reaction, but also causes inconvenient problems in that a mosquito net must be installed one by one.

Therefore, there was an inconvenience of having to frequently wash the equipment.

In addition, in the case of pest extermination, there is a problem of providing inconvenience to the user by generating minute noise due to the parts used.

In addition, as a conventional technology, there is a technology for controlling the wavelength of the LED by coating a phosphor on a blue LED, but when using a blue LED, the time and process are required as two coatings of a red phosphor and a green phosphor are required to coat the phosphor. It is not efficient in terms of

Accordingly, there is a need for a technology capable of manufacturing a light emitting unit capable of reducing the cost of raw materials and preventing access to pests with only one phosphor coating.

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

Prior to the description of the present invention, the following specific structure or functional descriptions are exemplified only for the purpose of describing embodiments according to the concept of the present invention, and embodiments according to the concept of the present invention may be implemented in various forms. , It should not be construed as being limited to the embodiments described herein.

In addition, since the embodiments according to the concept of the present invention can be modified in various ways and have various forms, specific embodiments will be illustrated in the drawings and described in detail in the present specification. However, this is not intended to limit the embodiments according to the concept of the present invention to a specific form of disclosure, and it should be understood that all modifications, equivalents, and substitutes included in the spirit and scope of the present invention are included.

Generally used lighting such as a fluorescent lamp has a high color temperature and high color rendering characteristics due to its wide physical characteristics, but due to this, ultraviolet rays (UV) are emitted and many insects and other flying insects are collected.

Lights such as 3 wavelengths do not emit ultraviolet rays, but the blue wavelength band (430nm) that pests like in RGB wavelengths is emitted a lot, helping to capture pests.

In contrast, the LED itself has a narrow wavelength band, so it is possible to avoid ultraviolet rays and 430nm blue wavelength bands, which are good environments for trapping pests, but due to this, the color temperature as lighting is much lowered.

1 is a view showing the structure of a light emitting unit for preventing pests according to the prior art, and FIG. 2 is a view for explaining a method of manufacturing a light emitting unit for preventing pests according to the prior art.

As shown in these figures, in the prior art, in order to solve the drop in color temperature, a phosphor emitting a wavelength band that pests do not like is coated on a blue light emitting device (LED) in a wavelength band of 470 nm, and red and The light emitting unit is implemented by additionally applying a phosphor in the green or yellow wavelength band. That is, by forming a wide wavelength band, the color temperature is increased, and ultraviolet rays and 430nm bands are minimized to filter only the wavelength band of 590nm to 630nm that pests hate.

However, in the prior art as described above, since the blue LED is used as a bass chip, the process of applying the phosphor must be performed twice, so that the process process is complicated and the manufacturing cost is increased.

Specifically, referring to the prior art illustrated in FIGS. 1 and 2, the conventional light emitting unit having a pest access prevention function includes a substrate 10, a blue light emitting device 20, and a light conversion layer 30. Is composed.

In addition, in the process of manufacturing a conventional light emitting unit, the epoxy resin and the red phosphor are mixed in a predetermined ratio (eg, 1:3 ratio) (see Fig. 2(a)).

The red phosphor is a fluorescent material such as red cadmium selenide (CdSe), and the weight ratio of the red phosphor and the epoxy resin is mixed in a ratio of 1:3. In other words, in the prior art, a colloidal solution method is used to synthesize the cadmium selenide nanoparticles in an epoxy resin.

At this time, the wavelength of the red fluorescent layer 31 may be adjusted according to the synthesis temperature and time.

The resin mixed with the red phosphor is applied onto the blue light emitting device 20 mounted on the substrate (see Fig. 2(b)).

Then, a red phosphor mixed with a resin is coated on the blue light emitting device 20, cured through heat treatment, and molded to form a red phosphor layer 31 (see Fig. 2(c)).

Thereafter, a green phosphor mixed with an epoxy resin is applied on the red phosphor layer 31 and cured through heat treatment to form a green phosphor layer 32 (see Fig. 2(d)).

As the green phosphor, a SiAlON-based compound and green cadmium selenide (CdSe) may be used.

Then, a green phosphor is applied on the red phosphor layer 31 and then heat-treated at 130° C. for 90 minutes.

The red phosphor layer 31 and the green phosphor layer 32 are photoconversion layers 30 that convert blue light emitted from the blue light emitting device 20 into a specific wavelength band (eg, white light).

As described above, in the prior art, as a blue light emitting device is used, a manufacturing process of forming each of the red phosphor layer and the green phosphor layer twice is required.

Hereinafter, a light emitting unit for preventing pests and a method of manufacturing the same according to the present invention for solving the problems of the prior art will be described in detail with reference to FIGS. 3 and 4.
