Embodiment 1

[0017] like figure 1 As shown, an LED lamp with an adjustable irradiation angle includes a groove-shaped lamp base 3, and an LED light-emitting part is arranged in the groove-shaped structure of the lamp base 3. It is characterized in that the LED light-emitting part includes two The adjusting plate 6, the lamp body fixing plate 4 and the LED lamp body 5 fixedly connected to the lamp body fixing plate 4 arranged in parallel, the adjusting plate 6 is fixedly connected to the lamp base 3, and the adjusting plate 6 is provided with Bolt holes, and the centerlines of the two bolt holes are collinear, both ends of the lamp body fixing plate 4 are fixedly connected with adjusting bolts 2, and each adjusting bolt 2 is respectively located in a bolt hole.

[0018] Specifically, in this setting, the LED lamp body 5 is fixedly connected to the lamp body fixing plate 4, and the lamp body fixing plate 4 is bolted to the adjusting plate 6 through the adjusting bolt 2. At this time, by loo...

Embodiment 2

[0020] The present embodiment is further limited on the basis of embodiment 1, as figure 1 As shown, in order to increase the irradiation range of the present invention and the intensity of light in the uniform irradiation area, there are multiple LED lamp bodies 5 fixedly connected to the lamp body fixing plate 4, and a plurality of LED lamp bodies 5 are arranged in rows .

[0021] In order to enable the present invention to meet different key irradiation areas at the same time, or to perform focused focused irradiation on a single irradiation area, there are more than one LED light emitting parts, and the LED light emitting parts are arranged in parallel.

Embodiment 3

[0023] The present embodiment is further limited on the basis of embodiment 1, as figure 1 As shown, in order to prevent the LED lamp body 5 from being affected by external moisture or other substances, a transparent lamp cover 7 for closing the groove-like structure is also provided above the lamp base 3 . Further, a condenser cover or a diffuser cover can be further arranged on the cover plate 7 of the lamp, so as to further enrich the light adjustment performance of the LED lamp.

[0024] In order to facilitate the direct connection of the present invention with a common AC power supply, a driving power supply 1 is also included, and the output end of the driving power supply 1 is connected to the power input end of the LED lamp body 5 .

Abstract

The invention discloses an LED (light emitting diode) lamp with an adjustable illumination angle. The LED lamp comprises a groove-shaped lamp base (3), wherein an LED luminous portion is arranged in a groove-shaped structure of the lamp base (3) and comprises two adjusting plates (6), a lamp body fixing plate (4) and an LED lamp body (5); the two adjusting plates (6) are parallel to each other; the LED lamp body (5) is fixedly connected to the lamp body fixing plate (4); the adjusting plates (6) are fixedly connected to the lamp base (3); a bolt hole is formed in each adjusting plate (6); center axes of the two bolt holes are collinear; two ends of the lamp body fixing plate (4) are fixedly connected with adjusting bolts (2); and each adjusting bolt (2) is positioned in the corresponding bolt hole. The illumination area of the LED lamp is conveniently adjusted in a certain range under the condition that the base of the LED lamp is adjusted after the LED lamp is mounted.

Description

technical field [0001] The invention relates to the field of lighting devices, in particular to an LED lamp with an adjustable irradiation angle. Background technique [0002] After decades of technological improvement, LED light source has become the mainstream product of modern lighting with its advantages of high luminous efficiency, low power consumption, long service life, strong safety and reliability, and environmental protection. Due to the light-emitting principle of LED lamps and their own structural characteristics, such as the chip material and the structure of the chip itself, the refractive index of the packaging glue, the appearance of the package, and the packaging process, the power angle generated by the LED lamp during the manufacturing process, That is, there is a certain difference in the light emitting angle. At the same time, compared with traditional lamps, the structural characteristics of LED lamps also cause their final luminous angle to be limite...
