Abstract
The utility model discloses an LED down lamp with an aluminum substrate. The LED down lamp comprises an LED light source component, a radiator and a bottom casing, wherein the LED light source component consists of an LED light source plate, the aluminum substrate and leads, the radiator connected with the LED light source component is used for dissipating heat of the LED light source component, the bottom casing is a ring with a boss, and a plurality of orifices are arranged at the bottom of the ring. By aid of the orifices arranged at the bottom casing, air below a ceiling flows into a cavity of the radiator via the orifices to form ceiling up-and-down air convection, thereby reducing temperature of the down lamp greatly. The LED light source component utilized by the down lamp is high in luminous efficiency, long in service life, fine in coloring index and similar to natural light. In addition, the LED down lamp has simple structure, attractive model and convenient installation.
Description
Technical field
The utility model relates to a kind of LED lighting, especially a kind of aluminium base LED Down lamp.
Background technology
Down lamp is the lighting of having many uses, and is widely used in the market, many places such as large supermarket, office space, hospital, school, hotel.What the Down lamp that uses was more at present is that halide lamp or fluorescent lamp are done light source, and there are shortcomings such as power consumption is big, the life-span is short, colour rendering index is low, light is not soft in above Down lamp.
Adopting LED is that the Down lamp usage ratio of light emitting source increases year by year, and led light source luminous efficiency height, little power consumption, life-span be long, photochromic to approach advantage such as natural daylight.But the Down lamp of which kind of type all will produce certain heat.Because Down lamp is mounted in the ceiling specific environment, have only the upper and lower formation cross-ventilation of ceiling in addition, the heat that could produce the Down lamp light emitting source effectively dissipates.And present all types of Down lamp, its structure all can not form the upper and lower cross-ventilation of ceiling preferably.
The utility model content
The utility model technical issues that need to address provide a kind of good heat dissipation, the Down lamp operating temperature is low, the aluminium base LED Down lamp of long service life.
For addressing the above problem, technical solution adopted in the utility model is: a kind of aluminium base LED Down lamp, comprise the led light source assembly that constitutes by led light source sheet, aluminium base, lead-in wire, and be led light source assembly radiating and connected radiator.And bottom shell, bottom shell is an annular that has boss, its bottom has some apertures.
This novel ground glass cover, reflection shield of also comprising, ground glass cover and reflection shield are fixed between radiator and the bottom shell, and an end shield of reflection shield is lived the aluminium base of led light source assembly, and the reflection shield other end props up the ground glass cover.
Described ground glass cover is circular.
Described reflection shield is tubaeform, and its horn mouth props up the ground glass cover for big mouthful, and the horn mouth osculum covers the aluminium base of led light source assembly.
Described radiator is an indent cylindrical aluminium radiator, and its outer wall is radial bead structures, and the rib direction is consistent with the radiator centerline direction.The led light source assembly is installed in the position, plane of the interior upper end of indent cavity of aluminium radiator, and its aluminium base closely is connected with the planar cavity wall of radiator, and lead-in wire is drawn by the aperture at position, radiator indent plane.
Circular power shell and inner power supply module further also are installed in the radiator upper end, and its circular power shell and radiator are fixed together.
Also be provided with clamp button of the spring on the described bottom shell.
Adopt the beneficial effect that technique scheme produced to be: the utility model is by having some apertures at bottom shell, the air that makes the ceiling below is in aperture flows to the radiator cavity, form the upper and lower cross-ventilation of ceiling, greatly reduce the Down lamp temperature.Adopt the led light source assembly, the luminous efficiency height, the life-span is long, colour rendering index good, near natural daylight, and this novel body structure is simple, handsome in appearance, easy for installation.
Description of drawings

Fig. 2 is the utility model plan structure schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
As shown in Figure 1, 2, the utility model comprises the led light source assembly that is made of led light source sheet 5, aluminium base 3, lead-in wire, be led light source assembly radiating and connected radiator 4, and be connected with radiator 4 and be used for fixing ground glass cover 10, reflection shield 6 and bottom shell 7.Wherein radiator 4 is an indent cylindrical aluminium radiator, its outer exterior wall is radial rib 11 structures, rib 11 directions are consistent with the radiator centerline direction, the led light source assembly is installed in the position, plane of upper end in the cylindrical radiator indent of the indent cavity, its aluminium base 3 closely is connected with the plane inner chamber of radiator 4 upper ends, and present embodiment adopts screw to fix.Lead-in wire is drawn by the aperture at aluminium radiator indent cavity inner plane position, is connected on the power supply module 2.Power supply module 2 is sealed in the circular shell 1, and circular shell 1 is screwed on radiator 4; Bottom shell 7 is fixed on ground glass cover 10 and reflection shield 6 between radiator 4 and the bottom shell 7.Reflection shield 6 is tubaeform, and its horn mouth props up ground glass cover 10 for big mouthful, and the horn mouth osculum covers the aluminium base 3 of led light source assembly.Ground glass cover 10 is circular, is installed in the bottom shell 7.
Described bottom shell 7 is an annular that has boss, and its bottom has some apertures 8, and corresponding with the space between the radiator rib 11, Down lamp is installed on the ceiling, can realize the upper and lower cross-ventilation of ceiling by aperture 8.
For the ease of installing, on bottom shell, also be provided with clamp button of the spring 9, during use Down lamp is stuck on the ceiling.
