Problems solved by technology

[0006] The purpose of the present invention is to overcome the Fresnel concave lens in the existing keel lamp in the prior art, which is only suitable for point light sources, not for linear light sources; the lens and lampshade are installed separately, and the cost is high; the keel lamp needs to be installed according to different positions. Adaptively select lampshades with different corresponding luminous angles. It is very inconvenient to install and purchase a variety of lampshades with different luminous angles. It is suitable for linear light sources and does not need to be additionally installed. Shaped Fresnel lens; Cylindrical Fresnel concave lens is integrally formed, low cost, easy to install and purchase; the luminous angle can be adjusted to avoid excessive light hitting the wall and save energy; during the installation preparation stage, It can reduce the types of U-shaped lampshades with different luminous angles. It is easy to install and can flexibly adjust the luminous angle at the installation site, which reduces the trouble of logistics and storage. Keel lights with variable luminous angles

specific Embodiment 1

[0039] Such as Figure 1-Figure 4 The specific embodiment 1 of a keel lamp with a variable luminous angle of the present invention is shown, which includes a keel 1, and the bottom surface of the keel 1 is provided with a lamp groove 2 throughout, and a U-shaped lampshade 3 is clamped in the lamp groove 2 The opening of the U-shaped lampshade 3 is provided with a PCB strip 4 along the length direction, and the top surface of the PCB strip 4 is fixed with several cooling blocks 5 for heat conduction with the keel 1, and the bottom surface of the PCB strip 4 is evenly arranged. There are a plurality of LED lamp beads 6, and each LED lamp bead 6 is located in the opening of the U-shaped lampshade 3; the bottom of the U-shaped lampshade 3 facing the LED lamp beads 6 is a cylindrical Fresnel concave lens 7, and the cylindrical Fresnel lens The serrated surface of the Er concave lens 7 faces the LED lamp bead 6, and the plane of the cylindrical Fresnel concave lens 7 is flush with t...

Embodiment 2

[0070] The difference between this embodiment and Embodiment 1 is that the angle between the two wing plates 12 is 20°, the surface of the U-shaped lampshade 3 is frosted, and the color is yellow, which can filter out the light below 500nm, and can be used in microelectronics workshops , liquid crystal panel production workshop, etc., the material of the PCB slat 4 is a copper substrate. Other structures and installation methods are the same as in Embodiment 1.

Abstract

The invention belongs to the technical field of LED lamp lighting and specifically relates to a keel lamp with variable luminous angle. The luminous angle variable keel lamp includes a keel. A lamp groove is formed in the keel. A U-shaped lampshade is connected with the interior of the lamp groove in a clamped mode. A PCB strip plate is installed in an opening of the U-shaped lampshade. Multiple heat dissipation blocks are fixed on the top surface of the PCB strip plate. Multiple LED lamp beads are distributed on the bottom surface of the PCB strip plate evenly. The shade bottom of the U-shaped lampshade is provided with a cylindrical Fresnel concave lens. The U-shaped lampshade is made of thermosensitive shape memory plastic. The luminous angle of the keel lamp is a first luminous angle or a second luminous angle. The luminous angle variable keel lamp has the beneficial effects that the luminous angle can be adjusted to avoid the fact that too much light glows on the wall, so that energy can be saved; in the period of installing preparation, the kinds of U-shaped lampshades with different luminous angles can be reduced, so that installing is convenient; the luminous angle can be adjusted flexibly in an installation site, so that logistics and warehousing problems are reduced; and the luminous angle variable keel lamp is suitable for a linear light source, so that extra installing of round Fresnel lenses corresponding to each LED lamp bead is not needed.

Description

technical field [0001] The invention belongs to the technical field of LED lamp lighting, and in particular relates to a keel lamp with a variable luminous angle. Background technique [0002] With the development of science and technology, higher requirements are put forward for the technology and process of clean workshops. The clean workshop is a fully enclosed structure and requires indoor lighting. The lamps used for lighting the clean workshop are generally called clean keel lamps. The installation of clean keel lamps usually adopts ceiling or embedded methods. The common size of embedded clean lamps is 600× 1200mm, it takes up a lot of space in the ceiling and hinders the installation of more FFU filter fans. It cannot be used in clean workshops with high cleanliness, which will cause dust accumulation and reduce the cleanliness of clean workshops. [0003] When installing the existing keel lamp, firstly, only the PCB strip assembly with integrated LED lamp beads is ...
