Light-emitting device

Abstract

A light-emitting device includes a light-transmitting airbag and a light strip disposed within the airbag. The light strip is equipped with at least one first light-emitting element and a plurality of second light-emitting elements. The light wavelength of the at least one first light-emitting element is between 570 nanometers and 620 nanometers. When the light-emitting device is placed in an outdoor environment and turned on, the light emitted by the at least one first light-emitting element in the 570-620 nanometer wavelength band penetrates the light-transmitting airbag and forms an optical shielding field around the light-emitting device. This induces a darkening response in mosquitoes, overcoming the drawback of traditional outdoor lighting fixtures that attract mosquitoes when providing illumination. When ambient lighting is needed, the second light-emitting elements are powered on to provide lighting functions that meet daily needs.

Claims

1. A light-emitting device, comprising: a light-transmitting airbag; and a light strip disposed in the light-transmitting airbag, the light strip having at least one first light-emitting element and a plurality of second light-emitting elements, the light wavelength of the at least one first light-emitting element being between 570 nanometers and 620 nanometers.

2. The light-emitting device as claimed in claim 1, wherein, The light-transmitting airbag defines an inflation chamber, the light strip is housed in the inflation chamber, and a heat-pressed joint is present around the periphery of the light-transmitting airbag.

3. The light-emitting device as claimed in claim 2, wherein, The light-transmitting airbag is made of a thermoplastic polyurethane frosted film with a thickness of at least 0.3 mm, and the light strip includes a flexible printed circuit board.

4. The light-emitting device as claimed in claim 1, wherein, The light-emitting device further includes at least one fixing member disposed on the outside of the light-transmitting airbag.

5. The light-emitting device as claimed in claim 4, wherein, The light-transmitting airbag comprises two membrane layers, and the at least one fixing member comprises a hanging structure and a magnet adjacent to the hanging structure, the magnet being disposed between the two membrane layers.

6. The light-emitting device as claimed in claim 1, wherein, At least one of the first light-emitting elements emits light with a wavelength of 575 nanometers.

7. The light-emitting device as claimed in claim 6, wherein, The at least one first light-emitting element defines a mosquito-repelling spectrum, the at least one first light-emitting element comprising a lumen value between 250 lumens and 1000 lumens.

8. The light-emitting device as claimed in claim 1, wherein, The light-emitting device further includes an inflation valve located at one end of the light-transmitting airbag, and the inflation valve is equipped with a check valve structure.
