For achieving the above object, this utility model employs the following technical solutions：

A kind of Down lamp, including lampshade, lampshade is in the horn-like and equal opening of its upper and lower ends, and the opening of lower end is more than upper end Opening, the outside wall surface of described lampshade lower end is provided with annular top, on a section by lampshade central shaft, described supports Top triangular shape, first summit of this triangle falls at the bottom of the outside wall surface of described lampshade.

The utility model has the advantage of：By changing the structure of lampshade lower end, after making Down lamp be arranged on ceiling, do not deposit In defect produced by the so-called flange of prior art, structure is simple and visual effect that possess innovation.

This utility model can be improved by following scheme：

Interior angle at the bottom of the outside wall surface near described lampshade for the described triangle is less than or equal to 90 degree.

Triangle its be referred to as base with the relative side in first summit, this base is perpendicular with described lampshade central shaft.

This triangle is right angled triangle, and described base constitutes wherein one right-angle side of this right angled triangle, right angle three Angular hypotenuse falls in the outside wall surface of described lampshade.

The end wall of described lampshade upper end upwardly extends the installation portion being provided with tubular, and the internal face of installation portion is provided with block Portion, the outside wall surface of installation portion is provided with some mounting seats in order to install for spring clip.

Down lamp also includes radiator and luminescence unit, and described radiator is arranged on lampshade, and described luminescence unit is arranged on On described radiator, radiator includes a substrate, and the first face of substrate is provided with the fixed part installed for luminescence unit, described base The central area position of the corresponding described fixed part in the second face of plate is convexly equipped with thermal column body, if the second face of described substrate is additionally provided with Dry radiating fin, each radiating fin outwards dissipates distribution from centered on described radiating cylinder, shape between radiating fin and radiating fin Become the air flow channel radially circulating along institute's radiator.

Specific embodiment

A kind of Down lamp as shown in accompanying drawing 3 is to accompanying drawing 6 includes lampshade 1, radiator 2 and luminescence unit 3.

Lampshade 1 is in the horn-like and equal opening of its upper and lower ends, and the opening of lower end is more than the opening of upper end, under described lampshade 1 The outside wall surface at end is provided with annular top 4, and on a section by lampshade 1 central shaft, described top 4 is triangular in shape Shape, first summit 41 of this triangle falls at the bottom 11 of the outside wall surface of described lampshade 1.By changing lampshade 1 lower end Structure, after making Down lamp be arranged on ceiling, there is not defect produced by the so-called flange of prior art, structure is simple and has The visual effect of standby innovation.

Interior angle at the bottom 11 of the outside wall surface near described lampshade 1 for the described triangle is less than or equal to 90 degree.

A kind of more excellent scheme is, triangle its be referred to as base 42 with the relative side in first summit 41, this base 42 with Described lampshade 1 central shaft is perpendicular.A kind of best mode is that this triangle is right angled triangle, and described base 42 is constituted should Wherein one right-angle side of right angled triangle, the hypotenuse 43 of right angled triangle falls in the outside wall surface of described lampshade 1.

The end wall of described lampshade 1 upper end upwardly extends the installation portion 12 being provided with tubular, the internal face setting of installation portion 12 There is stop section 13, the outside wall surface of installation portion 12 is provided with some mounting seats 14 in order to install for spring clip 5.

Described radiator 2 is arranged on lampshade 1 as shown in Figure 7, and described luminescence unit 3 is arranged on described radiator 2, Radiator 2 includes a substrate 21, and the first face of substrate 21 is provided with the fixed part 22 installed for luminescence unit 3, described substrate 21 The central area position of the corresponding described fixed part 22 in the second face be convexly equipped with thermal column body 23, the second face of described substrate 21 also sets Have some radiating fins 24, each radiating fin 24 outwards dissipates distribution from centered on described radiating cylinder 23, radiating fin 24 with Form the air flow channel 25 radially circulating along institute's radiator 2 between radiating fin 24.
