Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

Referring to fig. 1-2, an LED lamp holder according to a preferred embodiment of the present invention is used for being assembled on a lamp post, and includes a light emitting portion 1 and an installation portion 2, one end of the installation portion 2 is connected to the light emitting portion 1, the other end is connected to the lamp post, a light guide plate 12 is disposed on a lower surface of the light emitting portion 1, an array of recessed portions 121 is disposed on a surface of the light guide plate 12, the array of recessed portions 121 is composed of N unit recessed portions 121, where N is greater than or equal to 5300; light emitted from the LED lamp head passes through the light guide plate 12, is refracted by the concave portion 121, and then is irradiated to the ground.

Since the surface of the light guide plate 12 is provided with the array of recesses 121, the array of recesses 121 is composed of N unit recesses 121, and the recesses 121 disperse the light into soft light. Since the number of the unit recesses 121 exceeds 5300, the light distribution curve approaches a lambertian curve. The light refracted and diffused by the array of recessed portions 121 is also intersected with each other, so that the light emitted by the LED lamp beads 16 is uniform.

As the number of the unit depressions 121 is preferably larger, the larger the number of the unit depressions 121 is, the more difficult the processing and manufacturing is, and it is found by trial and error that in the conventional mainstream LED cap, when the number of the unit depressions 121 is 5300 or more, the light distribution curve of the LED cap approaches the lambertian curve. Therefore, in the present embodiment, the number of the recesses 121 is preferably set to 5300.

Specifically, the concave portion 121 is in the shape of a plano-concave lens and is formed by a laser engraving process. The focal length of the plano-concave lens structure is preferably as short as possible, and in the state of the art, the focal length is preferably 1mm to 1.8 mm.

Further, the light emitting portion 1 further includes a lamp housing 15 and an aluminum substrate 14, a first groove 151 is disposed in the lamp housing 15, the aluminum substrate 14 is attached to the upper surface of the first groove 151, a plurality of LED beads 16 are welded on the aluminum substrate 14, a light reflecting portion 13 is further disposed in the first groove 151, and the light not irradiated on the light guide plate 12 is reflected by the light reflecting portion 13. The utilization rate of light is improved, and the brightness is higher.

Further, the light reflecting portion 13 includes a light reflecting strip 131, and the light reflecting strip 131 is attached to the sidewall of the first groove 151. The light reflecting strips 131 not only reflect light, but also support the aluminum substrate 14 to form a distance between the aluminum substrate 14 and the light guide plate 12, so that the emitted light is more uniform.
