Problems solved by technology

However, this structure is not waterproof, and water droplets are easy to enter the interior of the lamp from the exposed threaded port. The lamps suitable for outdoor use must have waterproof function. Therefore, the existing structure for adjusting the focal length of the light source is not suitable for outdoor use and needs further improvement.

Abstract

The invention discloses a dimmable lamp, which comprises a lamp housing (1), a lamp holder (2), a lens (31), a lens ring (3) and a transparent cover plate (4). The lamp holder is provided with a light source (21), the lens ring (3) is sleeved on the periphery of the lens (31), a limiting groove (11) which is spirally arranged is disposed on the peripheral wall of the upper portion of the lamp housing (1), an adjusting ring (5) is further sleeved on the periphery of the upper portion of the lamp housing (1), a driving groove (51) which is axially disposed is arranged on the inner side wall of the adjusting ring (5), a matched dragging magnet (6) is embedded at an overlapping position of the limiting groove (11) and the driving groove (51), and a plurality of dragged magnets (7) are uniformly distributed on the periphery of the lens ring (3). Compared with the prior art, the dimmable lamp with the dimmable structure is structurally wrapped inside the adjusting ring by the aid of the magnets which drags or are dragged, a waterproof effect is excellent, the dimmable lamp is quite suitable to be used in an outdoor environment, adjusting action of the lens is stable and reliable, and a user uses the dimmable lamp comfortably.

Description

technical field [0001] The invention relates to a lamp, in particular to a dimmable lamp capable of adjusting the focal length of a light source. Background technique [0002] In recent years, with the rapid development of LED (Light Emitting Diode) technology, LED has been more and more used as a lighting source in people's daily necessities. At present, there are endless LED lights on the market. LED lights are light and energy-saving due to their light structure. Favored by consumers, many lights for outdoor use also use LED technology. At present, lamps for outdoor use generally include a lamp housing, a light source, a light-emitting circuit board, and a power supply arranged in the lamp housing. In order to enable the light source to irradiate a longer distance, a lens is often arranged on the front side of the light source. [0003] However, if the position of the lens relative to the light source is not adjustable, the illumination distance of the lamp is fixed and ...
