Description

Technical Field

[0001] This invention relates to the field of searchlight technology, specifically to an energy-saving searchlight for building construction. Background Technology

[0002] A searchlight is a device with a powerful light source and a concave mirror that can concentrate the light onto a specific direction for long-distance illumination and search purposes. The new LED light source has promoted innovation in the design and development of lighting fixtures. The design language and concepts of lamps can be freely developed and re-established. Lamps have more flexible space in the creative expression of visual perception and form. Searchlights will develop in a more energy-efficient, healthy, beautiful and human-centered direction.

[0003] While searchlights are widely used, they also bring a growing number of problems. For example, when using searchlights at construction sites at night, the excessive brightness can reflect into the eyes of workers, posing a danger and potentially leading to accidents. In summer, high temperatures and prolonged exposure to direct sunlight can cause searchlights to become brittle and shorten their lifespan. In construction environments, the lenses of searchlights often become covered in dust, resulting in dim light and unsatisfactory lighting effects, which can negatively impact construction.

[0004] To prevent safety hazards posed by searchlights and address issues such as lens self-cleaning and sun protection, an energy-saving searchlight for construction is needed to solve these problems. Summary of the Invention

The sponge block 64 is fixedly connected to the side of the positioning block 63 near the second lens component 5.

[0043] Working process and principle:

[0044] Before using the searchlight 2, first adjust the angle between the U-shaped strip 37 and the grooved plate 41. When the distance between the U-shaped strip 37 and the grooved plate 41 is increased, the gear 36 at the top of the U-shaped strip 37 meshes with the rack 33. At this time, the movement range of the groove block 34 at the bottom of the rack 33 is always within the outer wall of the limiting groove 38. The rack 33 moves towards the bottom of the limiting groove 38 as it meshes with the gear 36. At this time, the telescopic column 39 at the top of the rack 33 is pulled out, so that the arc plate 32 and the rack 33 move synchronously. The groove at the top of the positioning rod 31 matches the size of the protrusions on both sides of the arc plate 32, so that the arc plate 32 slides on the top of the positioning rod 31. Thus, when the searchlight 2 starts to illuminate at night, the beam height can be manually adjusted to avoid the light shining directly into the eyes of the workers, reduce the probability of the workers being exposed to strong light, avoid the situation where the light shines on the workers and causes safety accidents, and improve work efficiency.

[0045] When the searchlight 2 is powered on, the photoresistor 7 starts working. The stronger the daylight, the lower the resistance of the photoresistor 7, and the current flows to the first motor 44. The first motor 44 moves, and the first lens assembly 4 starts working. The first motor 44 causes the first telescopic rod 45 to move the first lens frame 46 towards the second groove 43 inside the lamp cover 1. When the first glass piece 47 in the first lens frame 46 moves to the fifth groove 61, the sponge block 64 cleans the dust on the first glass piece 47, so that when the first glass piece 47 continues to move, the dust remains on the surface of the sponge block 64. After being cleaned, the first glass plate 47 continues to move upward until the first lens frame 46 moves to the top of the second groove 43. The first glass plate 47 is snapped into the inner wall of the first lens frame 46. At this time, the light from the inner wall of the searchlight 2 shines through the first glass plate 47 and the searchlight 2 begins to work normally. This allows the searchlight 2 to work on the construction site. Dust falling on the lens during construction will reduce the working efficiency of the searchlight 2. The cleaning component 6 achieves automatic cleaning during the movement of the first glass plate 47, thereby improving the lighting effect of the searchlight 2.

[0046] When daytime turns into nighttime, the light is weaker, the resistance of the photoresistor 7 increases, and the current flows to the second motor 52. The second lens assembly 5 starts to work. When the first lens assembly 4 stops working, the first motor 44 stops moving. The first motor 44 causes the first telescopic rod 45 to move the first lens frame 46 into the third groove 51. When the first lens frame 46 contacts the sponge block 64, it rubs off the dust accumulated on the sponge block 64. The dust falling from the sponge block 64 falls out of the searchlight 2 through the third groove 51 and the cleaning hole 62 until the second glass plate 55 moves to the bottom of the third groove 51. After the second lens assembly 5 starts, it works in the same way as the first lens assembly 4. This allows the searchlight 2 to use lenses alternately under the control of light conditions. It also achieves lens cleaning while replacing lenses. The curved plate 32 can also prevent direct sunlight from shining on the searchlight 2, which would cause the searchlight 2 to become brittle and extend the working life of the searchlight 2.
