Lighting device for culture box

[0019] Such as figure 1 with figure 2 The illustrated lighting device for a culture box includes an aluminum substrate 4 having a cylindrical tubular structure. A plurality of LED lamp beads 5 are installed on the outer surface of the aluminum substrate 4, and the aluminum substrate 4 is provided with For the transparent cover 2 that wraps the LED lamp beads 5, the transparent cover 2 has a cylindrical tubular structure with the same height as the aluminum substrate 4, and there is a gap between the transparent cover 2 and the LED lamp beads 5. The aluminum substrate 4 And the upper end of the transparent cover 2 is provided with a sealing cover 1, the sealing cover 1 is installed with a terminal 7 for supplying power to the LED lamp beads 5, the terminal 7 is connected with the power supply wire 6, the aluminum substrate 4 and The lower end of the transparent cover 2 is provided with a heat dissipation base 3, the heat dissipation base 3 is provided with a plurality of heat dissipation fins 8 extending into the aluminum substrate 4, and the heat dissipation fins 8 are arranged closely to the inner wall of the aluminum substrate 4. The heat dissipation fins 8 are evenly arranged along the circumferential direction of the aluminum substrate 4.

[0020] In this embodiment, by using LED as the light source, energy is saved. At the same time, the entire lighting device is a cylindrical structure, which is reliably sealed up and down, and the external wiring is also specially equipped with terminal wiring, which can be used in humid environments very reliably in.

[0021] In this embodiment, the transparent cover 2 is a transparent acrylic cover, a transparent resin cover or a transparent glass cover.

[0022] The above are only the preferred embodiments of the present invention and do not limit the present invention. Any simple modification, change and equivalent structural transformation of the above embodiments according to the technical essence of the present invention still belong to the technology of the present invention. Within the protection scope of the program.
