[0002] The full name of ophthalmology is eye disease specialist, which is a discipline that studies diseases that occur in the visual system, including the eyeball and its associated tissues. Ophthalmology generally studies vitreous, retinal diseases, optometry, glaucoma and optic neuropathy, cataracts and other eye diseases. When ophthalmology is in the process of clinical treatment, it is generally treated with a shadowless lamp. When the shadowless lamp works continuously for a long time, the heat of the lamp is not easy to dissipate. Overheating will make the surgeon uncomfortable and dry the tissues in the surgical area. In addition, the internal components of the shadowless lamp may be damaged due to overheating. General shadowless lamps do not have a focusing function and cannot be focused for different surgical environments. Utility Model Content

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0021] Reference Figure 1-6 A shadowless lamp for clinical ophthalmology comprises a universal bracket 1, a lamp body 2, a ventilation sleeve 3 and a focusing assembly, wherein the universal bracket 1 is installed at the center position of the back of the lamp body 2, and a controller, an exhaust pipe 22, a ventilation cavity 6 and an LED lamp board 7 are arranged in the lamp body 2, and an LED lamp board 7 is embedded in the lower surface of the lamp body 2, and a glass cover 8 is covered on the lower surface of the lamp body 2 outside the LED lamp board 7, and the edge of the glass cover 8 is fixed to the lower surface of the lamp body 2 with bolts 82, and a ventilation cavity 6 is arranged in the lamp body 2 above the LED lamp board 7, and evenly divided LED lamp beads 71 ​​and evenly divided first ventilation holes 72 are embedded in the LED lamp board 7, and a plurality of LED lamp beads 71 ​​and evenly divided first ventilation holes 72 are arranged on the bottom wall of the ventilation cavity 6. 72 corresponds to the second ventilation hole 61, and the glass cover 8 is evenly provided with third ventilation holes 81. The bottom end of the exhaust pipe 22 is communicated with the top of the ventilation chamber 6, and the top end extends to the outside of the lamp body 2. A ventilation fan 221 is provided in the exhaust pipe 22, and a dust-proof and breathable net 21 is plugged on the top. The top opening of the ventilation cylinder cover 3 is screwed on the bottom of the lamp body 2. A plurality of L-shaped air intake pipes 31 are provided in the ventilation cylinder cover 3, one end of the L-shaped air intake pipe 31 leads to the interior of the ventilation cylinder cover 3, and the other end communicates with the outside of the ventilation cylinder cover 3. The position where the L-shaped air intake pipe 31 communicates with the outside of the ventilation cylinder cover 3 is plugged with a gas filter cotton net 4, and the focusing assembly is arranged on the bottom of the ventilation cylinder cover 3.

[0022] The direction of the lamp body 2 is adjusted through the universal bracket 1 (a bracket commonly used in hospital shadowless lamps, which will not be described in detail here), and the control panel on the shadowless lamp bracket structure is used to turn it on and set the parameters. When it starts working, the ventilation fan 221 blows air outward, causing a negative pressure in the ventilation chamber 6. The ventilation chamber 6 will inhale air from the first ventilation hole 72 and the corresponding second ventilation hole 61, and the air is inhaled from the inside of the ventilation cylinder sleeve 3 into the glass cover 8. The gas will absorb the hot air in the cover in time and discharge it outward. The air is filtered from the outside through the gas filter cotton net 4 to filter out dust and some water vapor. The gas filter cotton net 4 can be replaced regularly, and the dust-proof and breathable net 21 can prevent dust from falling into the ventilation chamber 6 when not working, and entering the LED lamp board 7, thereby affecting the internal work. Focusing is performed through the focusing component to achieve functions such as focusing or astigmatism.

[0023] Four exhaust pipes 22 are evenly arranged in the lamp body 2 near the outer wall, and a controller is arranged between the four exhaust pipes 22 .

[0024] The exhaust pipe 22 can be used to evenly exhaust the gas in the ventilation cavity.

It is ensured that the LED lamp bead 71 is in the glass cover 8, and the heat will not diffuse outward quickly, but will be taken away by the fast-flowing gas.

[0026] The number of the L-shaped air intake pipes 31 in the air exchange cylinder cover 3 is not less than 4, and the total length of all the L-shaped air intake pipes 31 is not greater than half of the length of the outer wall of the air exchange cylinder cover 3.

[0027] It is ensured that the gas is sucked into the ventilator sleeve 3 from the L-shaped air inlet pipe 31, and the gas can be evenly sucked in one circle, so that the gas entering the ventilator sleeve 3 is uniform.

[0028] The focusing assembly includes a convex focusing barrel 5 and a focusing lens. A cylindrical lens groove is provided in the convex focusing barrel 5. The focusing lens is plugged into the cylindrical lens groove. The top of the convex focusing barrel 5 is screwed into the bottom of the air changer sleeve 3. The distance is adjusted by the depth of the convex focusing barrel 5 screwed into the air changer sleeve 3 to achieve focusing.

[0029] The focusing lens is a lens with two convex surfaces 9 or a lens with two concave surfaces 10. The lens with two convex surfaces 9 realizes diffusion, and lenses with different convex degrees are selected according to needs; the lens with two concave surfaces 10 realizes focusing, and different concavities have different focusing degrees.
