fig. 2 is the utility model discloses a legend that LED lamp pearl distributes after the lamp stand expandes.

Reference numerals: 1. a lamp socket; 11. an inner cavity; 12. a conical projection; 2. a lamp shade; 21. a seal ring; 3. LED lamp pearl.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

As shown in fig. 1-2, an energy-saving underground lamp comprises a lamp holder 1, wherein the lamp holder 1 is provided with a cylindrical inner cavity 11, the upper end of the inner cavity 11 is provided with a lamp shade 2, a conical protrusion 12 is arranged on the central axis of the inner cavity 11, a reflective coating is arranged on the surface of the conical protrusion 12, a plurality of LED lamp beads 3 are arranged on the inner wall of the inner cavity 11, the plurality of LED lamp beads 3 are uniformly distributed around the conical protrusion 12, the plurality of LED lamp beads 3 are divided into a plurality of lamp bead groups, the LED lamp beads 3 of each lamp bead group are also uniformly distributed around the conical protrusion 12, and different lamp bead groups are independently controlled by different switches.

Be provided with circular cone arch 12 on the axis through inner chamber 11 at lamp stand 1, and distribute a plurality of LED lamp pearl 3 around circular cone arch 12 evenly, the light that single LED lamp pearl 3 sent shines to circular cone arch 12, and there is the divergence in the in-process of shining, can make a plurality of LED lamp pearl 3 send light shine at the protruding lateral wall of circular cone 12 evenly, the surface of circular cone arch 12 has reflective coating, circular cone arch 12 carries out the secondary reflection to the light that LED lamp pearl 3 sent, the light that makes LED lamp pearl 3 send upwards shines, finally make the light density distribution of the light through lamp shade 2 according to even. The power of the underground lamp can be reduced under the same power, namely, the underground lamp has higher brightness under the same brightness. Divide into a plurality of LED lamp pearl 3 and organize into a plurality of lamp pearls, LED lamp pearl 3 that every lamp pearl group also distributes around circular cone arch 12 evenly, under the condition that only uses a set of lamp pearl group, equally can make the optical density distribution of the light through lamp shade 2 according to even, and the difference lies in luminous lamp pearl less, and luminance is less. Can be according to this point, through the lamp pearl group with the difference through different switch ware independent control, bury the luminance of lamp controllingly, open more lamp pearl group when needing higher luminance, open less lamp pearl group when needing less luminance. This structure only needs to set up the switch block that corresponds in power supply circuit and can realize, does not have special requirement to LED lamp pearl 3 that use, also need not to set up the current adjustment structure in power supply circuit, avoids more electric quantity losses.

An included angle between a bus of the conical protrusion 12 and the bottom surface is preferably set to be 40-50 degrees, so that light emitted by the LED lamp bead 3 is incident on the side wall of the conical protrusion 12 at an incident angle of 45 degrees as much as possible, and the light emitted by the LED lamp bead 3 can be upward irradiated as much as possible.

The inner wall of the inner cavity 11 is also provided with a reflective coating, and the part of the light emitted by the LED lamp bead 3 which does not directly fall on the conical projection 12 can be reflected to the conical projection 12 again through the inner wall of the inner cavity 11.

In addition, set up lamp shade 2 into the lamp shade that has cellular grid, can further carry out diffuse reflection with the light through lamp shade 2, increase irradiation area, make light softer, reduce the glaring effect, play the effect of anti-dazzle.

A sealing ring 21 is arranged between the lampshade 2 and the lamp holder 1, so that water or vapor on the ground is prevented from entering the inner cavity of the lamp holder 1 from a gap between the lampshade 2 and the lamp holder 1, the LED lamp beads 3 are prevented from being damaged, and water leakage and electric leakage are avoided.

The above embodiments of the present invention are not right the utility model discloses the limited protection scope, the utility model discloses an embodiment is not limited to this, all kinds of basis according to the above-mentioned of the utility model discloses an under the above-mentioned basic technical thought prerequisite of the utility model, right according to ordinary technical knowledge and the conventional means in this field the modification, replacement or the change of other multiple forms that above-mentioned structure made all should fall within the protection scope of the utility model.
