The present invention relates to a light source module, and more preferably, to a light source module for insect repelling capable of preventing the incidence of insects.

In general, a light emitting diode (LED) is a light emitting diode that emits light. The light emitting diode emits light of various colors such as red, green, blue, and yellow, and is used as an electronic display board for various electronic products, .

In recent years, researches and product developments have been conducted on LEDs using LEDs, which are used for street lamps. Especially, among the lighting devices using LEDs for streetlight use, outdoor lighting capable of providing landscapes Research and products are being actively developed. For example, such outdoor lights include light ups that flood historic buildings or bridges, street lights in roads, squares, parks, apartment complexes, and the like.

Such outdoor lights emit light of various colors, among which blue light light attracts and attracts flysch and other moths. As a result, people who are engaged in nighttime activities under the outdoor lighting system may not only be disturbed by the appropriate nighttime activities due to the worms concentrated around the landscape lighting system, but may also be discomforted and even infected by pests such as mosquitoes . In order to combat insects concentrated around the outdoor lighting device, methods of spraying insecticide or expressing light of a wavelength range preferred by insects as separate lamps, attracting insects, burning them with a high voltage, Has been used.
