[0002] With the rise of socioeconomic development and the acceleration of urbanization, residential communities are springing up like mushrooms after rain. As an integral part of the residential environment, residential street lighting is closely related to people's daily lives, and as such, its design is attracting increasing attention. Currently, residential community street lighting designs are relatively well-designed in terms of safety, aesthetics, and energy efficiency, bringing convenience to people's lives, travel, and leisure and entertainment.
[0003] However, the brightness of existing streetlights in residential areas is usually fixed. Since the distances between streetlights and residential rooms in the community are usually different, in order to avoid affecting the living conditions of the rooms, the lighting range and brightness of each streetlight need to be adaptively adjusted.
[0004] The above information disclosed in this Background section is only for enhancement of understanding of the background of the present disclosure and therefore it may contain information that does not form the prior art that is already known to a person of ordinary skill in the art. Summary of the Invention
[0005] The purpose of the present invention is to design a new device and method for detecting glass scratches, which can detect scratches on the glass surface without the need for multi-angle lighting, so as to solve the above-mentioned shortcomings in the technology.
[0006] To achieve the above objectives, the present invention provides the following technical solutions: a rated energy-saving LED street lamp with adjustable lighting brightness, comprising a lamp holder mounted on a lamp pole, the lamp holder comprising a middle cover fixedly mounted to the lamp pole, an inner cover arranged at the bottom of the middle cover in the axial direction, an outer cover fixedly mounted on the inner cover, and a light source mounted within the middle cover, the outer cover being adjustable in axial position on the middle cover, and a light splitting chamber being formed between the inner wall of the middle cover, the outer wall of the inner cover, and the inner wall of the outer cover; By adjusting the axial position of the inner cover on the middle cover, the proportion of light emitted by the light source entering the inner cover and the spectroscopic chamber is distributed, and the brightness of the street lamp on the road surface is adjusted.
[0007] Preferably, a light-transmitting plate is fixedly installed inside the middle cover, the top of the inner cover passes through the light-transmitting plate and is slidably connected to the light-transmitting plate, the bottom of the light-transmitting plate, the outer wall of the inner cover, the inner wall of the inner cover and the inner wall of the outer cover form an insect-catching chamber, and the outer cover is provided with an insect inlet hole connected to the insect-catching chamber.
[0008] Preferably, the inner cover includes a light inlet pipe penetrating and slidably connected to the light-transmitting plate, a first frustum shell fixedly mounted on the bottom of the light inlet pipe, and a light-distributing plate fixedly mounted on the bottom of the first frustum shell.
[0009] Preferably, the middle cover includes a mounting tube fixedly mounted on the lamp pole, a second frustum shell fixedly mounted on the bottom of the mounting tube, and a connecting tube fixedly mounted on the bottom of the second frustum shell, the light-transmitting plate is fixedly mounted on the inner wall of the connecting tube, the light source is mounted in the mounting tube near one end of the second frustum shell, and the diameter of the light inlet tube is larger than the diameter of the mounting tube.
[0010] Preferably, the outer cover includes a third frustum shell fixedly connected to the second frustum shell, an adjustment tube fixedly mounted on the top of the third frustum shell, and an adjustment ring fixedly mounted on the top of the adjustment tube, and the adjustment ring is threadedly connected to the connecting tube.

[0016] In the above technical solution, the technical effects and advantages provided by the present invention are: The present invention changes the distance between the inner cover and the light source in the middle cover by rotating the outer cover forward and backward, thereby changing the proportion of light emitted by the light source entering the inner cover and the light-splitting chamber, thereby adjusting the brightness of the street lamp on the road surface according to demand; The present invention utilizes the light source in the spectroscopic chamber to emit light to the insect entrance hole and the adjustment ring in the insect trap chamber, thereby emitting light to the outside world (non-road surface). The light attraction of some mosquitoes is used to attract them to drill into the insect entrance hole, thereby achieving the function of attracting mosquitoes and alleviating the problem of a large number of phototactic mosquitoes in residential areas with high greening. At the same time, after the present invention attracts phototactic mosquitoes into the insect-catching chamber, the light irradiates the insect-catching chamber to generate heat, so that the mosquitoes in the insect-catching chamber will be dried and lose heat, thereby achieving the function of automatic insect killing; The present invention collects rainwater into the insect-catching chamber on rainy days, so that some mosquitoes drown in the chamber after their wings touch the liquid surface, or are unable to fly, thus reducing the number of mosquitoes that just crawl out of the insect entrance hole. The invention can also pour out the mosquito corpses in the insect-catching chamber by unscrewing the outer cover from the middle cover, which is easy to operate. At the same time, the product has a simple structure and is easy to injection mold. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to help those skilled in the art better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of this application.
[0021] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.
[0022] The present invention provides Figure 1-7 The illustrated embodiment of an energy-saving LED street lamp with adjustable lighting brightness includes a lamp holder 2 mounted on a lamp pole 1. The lamp holder 2 comprises a middle cover 2a, an inner cover 2b, an outer cover 2c, and a light source 2d. After installation, a spectroscopic chamber 3 is formed between the inner wall of the middle cover 2a, the outer wall of the inner cover 2b, and the inner wall of the outer cover 2c. By simply controlling the axial spacing between the inner cover 2b and the middle cover 2a, the proportion of light emitted by the light source 2d that enters the inner cover 2b and the spectroscopic chamber 3 can be controlled. For example, the closer the inner cover 2b is to the light source 2d within the middle cover 2a, the more light emitted by the light source 2d enters the inner cover 2b, thereby brightening the road surface. Conversely, the brightness of the street lamp illuminated by the street lamp decreases. The top of the inner cover 2b passes through the light-transmitting plate 4 and is slidably connected to the light-transmitting plate 4. The cavity between the bottom of the light-transmitting plate 4, the outer wall of the inner cover 2b, the inner wall of the inner cover 2b and the inner wall of the outer cover 2c forms an insect-catching chamber 5. The outer cover 2c is provided with an insect-entry hole 6 connected to the insect-catching chamber 5. Because part of the light entering the spectroscopic chamber 3 will pass through the light-transmitting plate 4 and enter the insect-catching chamber 5, and then be emitted from the insect-entry hole 6, some phototactic insects will crawl into the insect-catching chamber 5 through the insect-entry hole 6. Since the exit hole is smaller than the entire outer cover 2c, it is not easy for the insects to fly out. Because the light irradiates the insect-catching chamber 5, its interior will have heat, thereby drying the insects inside at night and consuming the moisture in their bodies, so as to achieve the purpose of attracting insects for killing. The lower the brightness of the street lamp shining on the road surface, the higher the insect-killing efficiency. The inner housing 2b includes a light inlet pipe 2b1 that penetrates and is slidably connected to the light-transmitting plate 4, a first frustum-shaped shell 2b2 fixedly mounted on the bottom of the light inlet pipe 2b1, and a light-dispersing plate 2b3 fixedly mounted on the bottom of the first frustum-shaped shell 2b2. After light from the light source 2d enters through the light inlet pipe 2b1, it is dispersed by the light-dispersing plate 2b3, ensuring that the light emitted by the street lamp is soft and does not cause local brightness abnormalities that may cause glare. The middle cover 2a includes a mounting tube 2a1 fixedly mounted on the lamp pole 1, a second frustoconical shell 2a2 fixedly mounted at the bottom of the mounting tube 2a1, and a connecting tube 2a3 fixedly mounted at the bottom of the second frustoconical shell 2a2. A light-transmitting plate 4 is fixedly mounted on the inner wall of the connecting tube 2a3. The light source 2d is mounted within the mounting tube 2a1 at one end near the second frustoconical shell 2a2. The diameter of the light inlet pipe 2b1 is larger than that of the mounting tube 2a1. When the end of the light inlet pipe 2b1 directly contacts the inner wall of the second frustoconical shell 2a2, it directly encloses the light source 2d, ensuring that all light enters the light inlet pipe 2b1, thereby achieving maximum brightness. The outer housing 2c includes a third frustoconical shell 2c1 fixedly connected to the second frustoconical shell 2a2, an adjustment tube 2c2 fixedly mounted on the top of the third frustoconical shell 2c1, and an adjustment ring 2c3 fixedly mounted on the top of the adjustment tube 2c2. The adjustment ring 2c3 is threadedly connected to the connecting tube 2a3. Rotating the third frustoconical shell 2c1 drives the adjustment ring 2c3 to rotate on the connecting tube 2a3, thereby adjusting the distance between the inner housing 2b and the middle housing 2a, and simultaneously changing the size of the insect-catching chamber 5. When the adjustment ring 2c3 is unscrewed from the connecting tube 2a3, the dead insects in the insect-catching chamber 5 can be dumped out. The light transmittance of the adjustment ring 2c3 is 25%-70%. The medium-low transmittance makes the brightness of the light emitted through the adjustment ring 2c3 lower than that of the light emitted from the insect inlet 6. This attracts insects to the light and drives them into the insect inlet 6. At the same time, during the day, light can also enter the insect-catching chamber 5, preventing the insects that survive in the insect-catching chamber 5 from following the light path and crawling out. A plurality of drainage holes 7 arranged in a circular array are provided between the adjustment tube 2c2 and the third frustum shell 2c1. During rainy days, rainwater can flow from the insect inlet 6 into the insect-catching chamber 5, drowning the insects. The drainage holes 7 also ensure the water level. The inner and outer walls of the inner cover 2b, the inner wall of the middle cover 2a, and the inner wall of the outer cover 2c are all mirror-coated. The hypotenuse angles of the first, second, and third frustums 2b2, 2a2, and 2c1 are all 45°. The mirror surface is used to reflect light, and the 45° angle is to facilitate the light to be directed to the adjustment ring 2c3. When the street lamp is turned on, if you want to increase the brightness, you can drive the third frustum shell 2c1 to rotate. The third frustum shell 2c1 drives the first frustum shell 2b2 to rise. The first frustum shell 2b2 drives the light inlet tube 2b1 closer to the light source 2d, thereby increasing the amount of light entering the light inlet tube 2b1. If you want to reduce the brightness, just rotate in the opposite direction. Part of the light emitted by the light source 2d will enter the light inlet tube 2b1, and part will enter the spectroscopic chamber 3, and then pass through the light-transmitting plate 4 to enter the insect-catching chamber 5 to irradiate, dry and kill the insects. After that, it will pass through the adjustment ring 2c3 and the insect inlet hole 6 to be emitted. At night, some phototactic insects will be attracted to the adjustment ring 2c3 and enter the insect-catching chamber 5 through the insect inlet hole 6 with higher brightness. When there are too many insect corpses, the user can unscrew the outer cover 2c and pour out the insect corpses.
