Abstract
Description
Technical Field
[0001] The present disclosure relates to the technical field of lighting equipment, and in particular to a sealed focus spotlight and lighting equipment. Background Art
[0002] Spotlights are usually used for indoor or outdoor lighting. Since the outdoor environment is more severe than the indoor environment, the waterproof and dustproof capabilities of spotlights are required to be higher. Traditional spotlights are mainly considered for indoor use, which makes the waterproof and dustproof capabilities of spotlights lower. Moreover, when adjusting the focal length of the spotlight, the spotlight needs to be disassembled and the lens position moved to change the focal length of the spotlight, thereby achieving the focal length adjustment of the spotlight. However, in order to facilitate the disassembly of the spotlight, a gap is generally left on the outer casing of the spotlight, further reducing the sealing effect of the spotlight.
[0003] Prior art, such as patent CN111336427A, proposes a focus adjustment device for an optical spotlight, which discloses a lamp tube. An annular retaining ring is formed on the inner wall of the front end of the lamp tube, and a sealing ring is provided on the front end surface of the retaining ring. The front end surface of the sealing ring abuts against a transparent cover plate; an annular groove and an external thread are formed on the outer wall of the front end of the lamp tube. An annular tube cover is screwed to the front end of the lamp tube, and a pressing sleeve is formed on the inner ring of the tube cover. The pressing sleeve presses against the cover plate, thereby improving the sealing performance of the focus adjustment device; an inner magnet ring is inserted into the lamp tube behind the retaining ring, and a convex lens is embedded in the inner magnet ring; The outer sleeve of the lamp tube is provided with an annular sliding sleeve, and an annular groove is formed on the inner wall of the sliding sleeve. An outer magnet ring that is attracted to the inner magnet ring is inserted into the groove of the sliding sleeve, so that when the sliding sleeve slides relative to the outer wall of the lamp tube, the outer magnet ring can drive the inner magnet ring to move relative to the lamp tube. At the same time, the inner magnet ring can also drive the convex lens to move relative to the lamp tube, so that the above-mentioned focal length adjustment device can adjust the focal length of the spotlight by magnetic adjustment. Compared with traditional spotlights, the above-mentioned focal length adjustment device does not need to leave a gap for easy disassembly, thereby making the above-mentioned focal length adjustment device more waterproof and dustproof.
[0004] However, the contact surface between the copper sheet of the focus adjustment device and the wall of the heat dissipation groove is relatively smooth, so that the friction between the copper sheet and the wall of the heat dissipation groove is too small. When the sliding sleeve is subjected to external collision, the sliding sleeve will drive the convex lens to deviate from the originally set position, causing the focal length of the spotlight to change, thereby making the focus adjustment stability of the focus adjustment device poor; at the same time, there is a gap between the sliding sleeve of the focus adjustment device and the heat dissipation groove, so that the copper sheet arranged in the heat dissipation groove is directly in contact with the outdoor environment, which accelerates the oxidation and rusting speed of the copper sheet. For example, in a humid and oxygen-rich outdoor environment, the copper sheet will be easily damaged. It may react with chloride ions to form cuprous chloride, which further reacts to form basic cupric chloride (green powdery rust). This type of rust is called "bronze disease" and will spread rapidly and damage the copper sheet. When the copper sheet rusts to a certain extent, the elastic deformation ability of the copper sheet will decrease, thereby reducing the pressure between the copper sheet and the groove wall of the scattering groove, and the friction between the copper sheet and the groove wall of the scattering groove will also decrease. As a result, the above-mentioned focal length adjustment device will cause the sliding sleeve to drive the convex lens to deviate from the originally set position under the action of its own gravity or external collision, further reducing the focus adjustment stability of the above-mentioned focal length adjustment device.

Compared with traditional spotlights, the sealed focus spotlight 10 is more convenient and quick through the above-mentioned magnetic adjustment method, thereby making the sealed focus spotlight 10 more easy to use.
[0058] 2. Since the end face of the shell 100 is connected to the sealed lampshade 200, the shell 100 and the sealed lampshade 200 jointly form a sealed cavity 110, and the light-emitting component 310 is arranged in the sealed cavity 110 to prevent external water or dust from entering the sealed cavity 110 and causing a short circuit in the light-emitting component 310, thereby extending the service life of the light-emitting component 310; at the same time, the sealed focus spotlight 10 is focused by the above-mentioned magnetic adjustment method. Compared with traditional spotlights, the sealed focus spotlight 10 does not need to leave a gap for easy disassembly, ensuring that the sealed focus spotlight 10 still has a good sealing effect during the focusing process, thereby making the sealed focus spotlight 10 more waterproof and dustproof.
[0059] 3. Since the friction limit surface 411 can increase the roughness of the wall of the guide limit through hole 410, the friction between the sliding end of the magnetic adjustment limit component 510 and the wall of the guide limit through hole 410 is increased, so that the light-emitting element 310 can be more firmly positioned on the fixing frame 400 through the friction between the sliding end of the magnetic adjustment limit component 510 and the wall of the guide limit through hole 410, thereby making the focus adjustment stability of the sealed focus spotlight 10 higher; at the same time, the sealed focus spotlight 10 can also avoid The fixing frame 400 and the magnetic adjustment component 510 are exposed to the outdoor environment, so that the sealed focusing spotlight 10 can effectively curb the oxidation corrosion rate of the fixing frame 400 and the magnetic adjustment component 510, so that during the long-term use of the sealed focusing spotlight 10, the light-emitting part 310 can still be firmly positioned on the fixing frame 400 by relying on the friction between the sliding end of the magnetic adjustment component 510 and the friction limit surface 411 of the guide limit through hole 410, further improving the focus adjustment stability of the sealed focusing spotlight 10.
