Abstract
Description
Technical Field
[0001] The utility model relates to an improvement of a downlight, in particular to an improvement of a downlight which is convenient for adjusting a large angle. Background Art
[0002] LED downlight is a lighting product that uses a new type of LED lighting source and is based on the design of traditional downlights. It has the advantages of energy saving, low carbon, long life, good color rendering and fast response speed.
[0003] Downlights are designed to be light and beautiful, easy to install, and can maintain the overall unity and perfection of building decoration. This type of lamp is not exposed, avoiding glare, making the visual effect softer and more uniform. Downlights are directional lighting fixtures with concentrated light and strong contrast between light and dark, which can highlight the illuminated objects. They are suitable for shopping malls, supermarkets, office buildings and other environments. In addition, downlights also have excellent heat dissipation performance, which can effectively extend the service life of the light source and reduce maintenance costs.
[0004] However, LED downlights also have the disadvantage of fixed irradiation direction. In order to overcome this disadvantage, some downlights are now equipped with a rotatable inner core. The LED light board is installed in the inner core. The inner core is connected to the outer shell through an obliquely installed hollow screw tube. The wire is connected to the LED light board through the hollow screw tube. The inner core can be rotated eccentrically to adjust the direction of the irradiated light.
[0005] However, since the external wires of this type of downlight are directly inserted into the hollow spiral tube, the wires are easily installed at an angle. When the downlight is rotated at a large angle, the inner core will be automatically deflected by the force of the wires during the rotation, affecting the adjustment of the irradiation angle. Utility Model Content
[0006] In order to overcome the shortcoming that the existing downlights which are easy to adjust the angle are prone to automatic deflection, the utility model provides a downlight which is easy to adjust the angle.

[0008] In order to facilitate heat dissipation, the hemispherical inner shell is made of metal, and a heat conductive block is provided on the inner side of the hemispherical inner shell, and another section of the heat conductive block abuts against the lamp board.
[0009] A preferred embodiment of the wire is that a male plug is provided at the other end of the wire exposed outside the housing.
[0010] To further facilitate rotation, the nut tube is also provided with a first gasket, a second gasket and a third gasket. The first gasket is located between the screw head and the hemispherical inner shell, the second gasket is located between the hemispherical outer shell and the hemispherical inner shell, and the third gasket is located between the hemispherical outer shell and the nut.
[0011] In order to improve the light conversion efficiency and reduce heat consumption, a reflective cup is provided between the hemispherical inner shell and the lens.
[0012] To further increase the heat dissipation performance, the cover is provided with a plurality of heat dissipation slots.
[0013] The utility model is different from the prior art downlight with adjustable angle when in use, in that the wire is fixed on the wire fixing clamp and then passed into the nut tube, so that the hemispherical inner shell will not automatically deflect.
[0014] The beneficial effects of the utility model are: 1. A bridge is set up, and a retaining spring and a wire fixing clamp are installed on the bridge.

Compared with traditional adjustment solutions, this new design avoids problems such as complex structure and excessive product size, making operation more convenient and user experience more friendly. 3. When rotating at a large angle, it is not easy to automatically deflect and return to its position compared to those without a wire fixing clamp. BRIEF DESCRIPTION OF THE DRAWINGS
