Abstract
The utility model relates to the technical field of down lights, in particular to an LED down light, which comprises a light shell, a circuit board and a heat sink are arranged in the light shell, the heat sink is arranged on one end of the circuit board, the other end of the circuit board is electrically connected with an LED light, which comprises a plurality of LED beads, the light shell is connected with a transparent board, and a light-focusing sheet is arranged in the transparent board. Since the utility model arranges the heat sink in the light shell, the structure is reasonable, the heat of the LED light can be directly dissipated by the heat sink, consequently, the heat-dissipating effect is good, and the service life can be prolonged; and in addition, since the light-focusing sheet is arranged in the transparent board, the cooperation between the light-focusing sheet and the transparent board can ensure that emergent light is uniform and not dazzling.
Description
Technical field
The utility model relates to the Down lamp technical field, especially relates to a kind of LED Down lamp.
Background technology
Down lamp is to plant to be embedded in the ceiling lighting of light down-ejection type.Its maximum characteristics are exactly to keep the integral body of building decoration unified and perfect, can not destroy the perfect unity of furred ceiling art because of the setting of light fixture.Its structural advantages is to be hidden in building decoration inside to light source, and light source does not leak outside, free from glare, and visual effect is soft, even.
Along with development of science and technology; Common in the market LED Down lamp; Basically be conventional lighting sources simply to be replaced to LED process, what have also can form the frosted layer on light-emitting plate, carry out simple optical treatment; Yet this series products exist bright dipping inhomogeneous, have dazzling, structural design is not too reasonable, radiating effect is limited.
The utility model content
To the deficiency that above-mentioned prior art exists, the purpose of the utility model provides a kind of LED Down lamp, and it has, and bright dipping is even, rational in infrastructure, good heat dissipation effect, the characteristics that can increase the service life.
To achieve these goals, the technical scheme that the utility model adopted is: a kind of LED Down lamp comprises lamp housing; Be provided with circuit board and heat abstractor in the said lamp housing; Said heat abstractor is located at an end of said circuit board, and the other end of said circuit board is electrically connected with the LED lamp, and said LED lamp comprises several LED lamp grains; Said lamp housing is connected with light-passing board, and said light-passing board is built-in with a concentration piece.
Wherein, said lamp housing is equipped with retaining collar.
Wherein, said retaining collar is provided with hangers, and said hangers is connected with drop handle.
Wherein, the bottom of said lamp housing offers the heat abstractor hole.
After adopting said structure, the utility model is compared the advantage that is had with prior art and is: the utility model comprises lamp housing, is provided with circuit board and heat abstractor in the said lamp housing; Said heat abstractor is located at an end of said circuit board, and the other end of said circuit board is electrically connected with the LED lamp, and said LED lamp comprises several LED lamp grains; Said lamp housing is connected with light-passing board, and said light-passing board is built-in with a concentration piece, and the utility model is arranged at said heat abstractor in the lamp housing; Rational in infrastructure, heat abstractor can directly be dispelled the heat, Gu good heat dissipation effect, can increase the service life to the LED lamp; Be built-in with a concentration piece at said light-passing board in addition; Said concentration piece and said light-passing board are used, and can make bright dipping even, free from glare.
