Description

Technical Field

[0001] The utility model belongs to the technical field of LED lamps, and in particular relates to an outdoor LED floodlight with an anti-collision function. Background Art

[0002] LED floodlights are also known as LED spotlights and LED projection lights. LED floodlights are controlled by built-in microchips. There are currently two types of products, one using a power chip combination and the other using a single high-power chip. The former has more stable performance and a single high-power product has a large structure, which is suitable for small-scale projection. The latter can reach very high power and can project light over a long distance and over a large area.

[0003] At present, some large-scale activities are carried out at the scene, and more LED floodlights are used, and these LED floodlights can be rotated at different angles to present different lighting effects. However, when in use, some birds are often attracted by the lights and hit the LED floodlights, causing damage to the LED floodlights and affecting the effect of the activities. However, the existing LED floodlights have a measure to prevent collisions by installing a transparent cover on the outside of the LED floodlights to prevent collisions. However, the bearing capacity of the transparent cover is limited. After suffering multiple collisions, the transparent cover will still break. Moreover, the existing LED floodlights do not have measures to buffer the collisions, so that the transparent cover of the light directly contacts the impacting object, thereby increasing the risk of the transparent cover breaking, so improvements are needed. Utility Model Content

[0004] In view of the above technical problems, the utility model provides an outdoor LED floodlight with an anti-collision function, which can rotate after being hit to play a role of buffering and protection.

[0007] The elastic component includes a guide shaft and a support spring. The guide shaft is fixedly connected to the lamp body, the lampshade is slidably connected to the guide shaft, the support spring is sleeved outside the guide shaft, and two ends of the support spring are respectively in contact with the lamp body and the lampshade.

[0008] The connecting prism is plugged into the supporting frame, and a limiting ring is provided on the connecting prism; the connecting prism is provided with a connecting through hole rotatably connected to the connecting shaft.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present utility model are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0023] like Figure 1-6 As shown, an outdoor LED floodlight with anti-collision function includes a lamp body 1, a lamp holder 2 and a lamp shade 5. A support frame 3 is rotatably connected to the lamp holder 2. Connecting shafts 4 are fixed at both ends of the lamp body 1. The lamp body 1 is supported by the support frame 3. Specifically, the support frame 3 and the lamp holder 2 can be rotatably connected by a damping shaft in the prior art. The lamp shade 5 is made of a transparent material.

[0024] The lampshade 5 is slidably connected to the lamp body 1 , and an elastic component is provided between the lampshade 5 and the lamp body 1 ; when the lampshade 5 is impacted, the lampshade 5 will move and the elastic member in the elastic component will be elastically deformed.

[0025] An angle limit frame 6 is fixed on the lampshade 5, and a limit surface 7 is arranged inside the angle limit frame 6. Both sides of the support frame 3 are provided with connecting prisms 8 that cooperate with the limit surface 7; the connecting shaft 4 is rotatably connected to the connecting prism 8 on the corresponding side.

[0026] When in use, the lamp holder 2 is installed at the desired position by means of bolts or the like; and the support frame 3 is rotated according to the required horizontal angle. When the pitch angle of the lamp body 1 needs to be changed, the lampshade 5 is first pressed to separate the limiting surface 7 and the connecting prism 8 from contacting each other, and the lamp body 1 can be freely rotated at this time; after rotating to a suitable angle, the pressing on the lampshade 5 is cancelled. The elastic member in the elastic component releases elastic potential energy, driving the lampshade 5 and the angle limiting frame 6 to move, so that the limiting surface 7 contacts the corresponding side of the connecting prism 8, thereby fixing the angle of the lamp body 1. The connecting prism 8 preferably adopts an enumerator, and of course, a hexagonal prism, a heptagonal prism, an octagonal prism, etc. can also be selected according to the situation.

[0027] When a flying bird hits the lampshade 5, the limiting surface 7 and the connecting prism 8 will separate, and the lamp body 1 will rotate under the impact and gravity. Compared with the fixed position of the lamp body 1 in the prior art, the rotation of the lamp body 1 can alleviate the impact and reduce the degree of damage to the lamp body 1 and the flying bird.

[0028] Furthermore, the elastic component specifically includes a guide shaft 9 and a support spring 10 (elastic member), and the support spring 10 is preferably a cylindrical spring. The guide shaft 9 is fixedly connected to the lamp body 1, and the lampshade 5 is slidably connected to the guide shaft 9, and one end of the guide column can extend through the lampshade 5. The support spring 10 is sleeved outside the guide shaft 9, and the two ends of the support spring 10 are in contact with the lamp body 1 and the lampshade 5 respectively. When the lampshade 5 is hit or pressed, the lampshade 5 moves along the guide shaft 9 and the support spring 10 is compressed, thereby generating elastic potential energy.

[0029] Furthermore, in order to facilitate installation and disassembly, the connecting prism 8 is plugged into the support frame 3, and a prismatic hole of a corresponding shape is provided on the support frame 3, and the connecting prism 8 cannot rotate after insertion. A limiting ring 11 is provided on the connecting prism 8, and the limiting ring 11 is in contact with the support frame 3. During installation, the connecting prism 8 is inserted into the prismatic hole from the outside of the support frame 3, and the limiting ring 11 is in contact with the support frame 3 to be installed in place. Specifically, a connecting through hole 12 is provided on the connecting prism 8 to be rotatably connected to the connecting shaft 4.

[0030] Furthermore, similarly, in order to facilitate installation and disassembly, the connecting shaft 4 is threadedly connected to the lamp body 1; one end of the connecting shaft 4 is provided with a thread, and the lamp body 1 is provided with a corresponding threaded blind hole.

[0031] Furthermore, a counterweight assembly 13 is included, and the counterweight assembly 13 is connected to the two connecting shafts 4. The counterweight assembly 13 can play a role in increasing the counterweight, that is, it can play a role in providing initial power, so that the lamp body 1 has a tendency to rotate; when a flying bird or the like hits the lampshade 5, the limiting surface 7 and the connecting prism 8 will be separated, and under the effect of this tendency and the impact force of the flying bird or the like, the lamp body 1 will rotate accordingly.

[0032] Further, the counterweight assembly 13 includes a connecting rod 14 and a counterweight rod 15. Two connecting rods 14 are provided. The two connecting rods 14 are respectively rotatably connected to the corresponding connecting shaft 4, and a limit screw 16 is provided at the rotation connection. The two ends of the counterweight rod 15 are respectively connected to the two connecting rods 14. Specifically: the connecting rod 14 is provided with a corresponding threaded through hole, and one end of the limit screw 16 can pass through the threaded through hole and abut against the connecting shaft 4; by tightening the limit screw 16, the connecting rod 14 can be fixed to limit its rotation.

[0033] After the pitch angle of the lamp body 1 is adjusted, the connecting rod 14 is rotated to make the counterweight rod 15 be at an obliquely upward angle; finally, the limiting top screw 16 is tightened to fix it.

[0034] Furthermore, the two ends of the counterweight rod 15 are respectively slidably connected with the two connecting rods 14, and the two ends of the counterweight rod 15 extend through the connecting rods 14 and are threadedly connected with the limit nuts 17. The counterweight rod 15 can be slid as needed to change its position, that is, the length of the force arm between it and the connecting shaft 4 can be changed. This ensures that the counterweight rod 15 can provide sufficient downward force for the rotation of the lamp body 1 after being separated between the limit surface 7 and the connecting prism 8.

[0035] Only the preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments.
