Description

Technical Field

[0001] The utility model relates to the technical field of lamp sources, in particular to a columnar light source. Background Art

[0002] Commonly used tube-type light sources for photocatalysis are high-pressure mercury lamps, xenon lamps, mercury-xenon lamps, metal halide lamps, etc. In the process of photocatalysis, the light source is generally cooled by placing a cold trap outside the lamp tube. Such light sources perform well at specific wavelengths, such as mercury lamps in the ultraviolet band and xenon lamps in simulating sunlight, but they perform poorly for single wavelengths or when the wavelength is adjustable. LED has irreplaceable advantages in achieving these two aspects. In addition, the light source also has stronger light power output at a certain wavelength, and stronger deformation ability can meet small volume, multiple lengths and other structural conditions. However, the LED itself needs to meet its heat dissipation requirements to work efficiently.

[0003] In the prior art, other similar products include corn lamps, fishing lamps, and light fermentation tanks, etc. However, due to the special occasions where the products are used, the structural requirements cannot be adapted to our scenarios. For example, the comparative document 1CN201320883508.1 provides a built-in light source water cooling rack for a light fermentation tank, including a cylindrical cylinder, and LED light source mounting grooves are arranged on the outer circumference of the cylindrical cylinder. The LED light source mounting grooves of two adjacent rows are staggered, thereby making the heat dissipation better. A cooling water channel is arranged between the two adjacent rows of LED light source mounting grooves, and the aperture of the cooling water channel is 2-4 mm; the cooling water channel is arranged longitudinally along the cylindrical body and passes through the upper and lower end faces of the cylindrical body. The upper and lower end faces of the cylindrical body are respectively provided with connecting grooves that can communicate with adjacent cooling water channels. The connecting grooves on the upper and lower end faces of the cylindrical body are staggered and connect the cooling water channels end to end to form a complete fluid medium channel. The upper and lower end faces of the cylindrical body are respectively covered with sealing gaskets and pressure plates. The connecting grooves covered by the pressure plate can connect the cooling water channels in series to form a complete internal circulation channel. The pressure plate on the upper end face of the cylindrical body is provided with a water inlet pipe and a water outlet pipe connected to the internal circulation channel. The fermentation heat and the heat of the lamp beads are removed by water cooling and an annular light source frame, but this structure is relatively large and is not suitable for replacing scenes of tens of millimeters.

In order to take away all the heat energy generated by the lamp beads 13, the fluid medium enters the water inlet chamber 4 from the position of the first water inlet 3, and flows to the first water outlet 11 through the return water chamber 6. Since the return water chamber 6 is arranged on the periphery of the water inlet chamber 4, and the outer side wall of the return water chamber 6 is arranged as a heat exchange profile, heat exchange is carried out in the return water chamber 6. Since the return water chamber 6 is arranged in an annular shape, the heat energy around the main body 9 can be exchanged in the return water chamber 6 to reduce the heat around the lamp beads 13.

[0028] With such arrangement, the water inlet chamber 4 and the water return chamber 6 extending along the axial direction of the main body 9 can exchange the heat energy generated by the lamp beads 13 at any position, thereby increasing the heat exchange area. At the same time, both the structure and the heat dissipation can meet the use scenario of circumferential illumination under small diameter and high power.

[0029] In this embodiment, in order to increase the heat exchange effect, a plurality of heat exchange fins 5 are arranged on the inner peripheral surface of the outer wall of the return water chamber 6.

An area where the heat exchange fins 5 can exchange heat is arranged in the return water chamber 6, thereby increasing the heat exchange efficiency.

[0030] In this embodiment, the main body 9 includes a first columnar section 91 with a cylindrical outer circumference and a second columnar section 92 with a polygonal outer circumference. The lamp beads 13 are arranged on the outer circumference of the second columnar section 92. At the same time, the fluid medium first passes through the second columnar section 92, which can exchange the energy of the second columnar section 92 to the greatest extent to carry away the heat energy generated by the lamp beads 13.

With this arrangement, the function of light source identification is realized on the control board, and the control system can turn on and off different lamp beads 13.

[0037] In order to reduce the output of wires, a thermal sensor 15 is provided on each substrate 12 , wherein the thermal sensors 15 are gathered at the position of the control board and then electrically connected to the control system on the electric control box 7 , so as to realize the control of the lamp beads 13 by the electric control system.

[0038] In this embodiment, in order to protect the lamp bead 13 well, an outer glass column 10 is arranged on the outside of the lamp bead 13, and the outer glass column 10 is installed on the main body 9. A support member 8 for supporting the outer glass column 10 is arranged between the second end of the main body 9 and the outer glass column 10, so that the outer glass column 10 can be well supported.
