Description

A kind of LED Down lamp

Technical field

The utility model relates to civilian or commercial Down lamp, specifically a kind of LED Down lamp.

Background technology

Down lamp be a kind ofly be embedded in ceiling, the 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 because of the setting of light fixture the perfect unity of furred ceiling art.This hidden the putting property light fixture that is flush-mounted in ceiling inside, all light is projection downwards all, belongs to direct light projector.Down lamp can directly be loaded onto the light fixture of incandescent lamp or electricity-saving lamp, because the efficiency of incandescent lamp and electricity-saving lamp is lower and the life-span is very short, fully by LED light source, is replaced now.

LED light source be the 4th generation light source, energy-conserving and environment-protective, pollution-free, without stroboscopic, safety is without hidden danger, maximum characteristics are that the life-span is long, can reach in theory 50000 hours.

At present, adopt single 1W or high-power module (C0B) fully in the LED Down lamp, light emitting anger is all between 120～140 degree, and Down lamp belongs to the direct illuminating lamp series products, need low-angle light source, need to install lens additional with the 1W high power light source and just its angle can be dwindled, its shortcoming be cost high, reduced luminous efficiency again, particularly high-power module (COB) heating is serious, needs the heavier radiator of configuration.

And the direct insertion LED of small-power can't high density concentrate use in Down lamp in the past, its reason is that straight cutting LED is welded on wiring board while forming high-power use thick and fast, the heat of its generation can not conduct timely and effectively, spread out, cause straight cutting LED temperature rise too high, accelerate the lamp pearl aging, have a strong impact on the service life of light fixture, under this environment, work and usually only have the time of short some months; And the LED Down lamp wants continuous operation more than ten hours in common one day, if there is no reliable heat dissipation technology, be the reliably working of having no way.

The utility model content

In order to solve the problems such as existing Down lamp luminous efficiency is low, radiating effect is poor, service life is short, the purpose of this utility model is to provide a kind of LED Down lamp.

The purpose of this utility model is achieved through the following technical solutions:

The utility model comprises lamp body, wiring board, micarex and base, wherein base is connected with lamp body, described wiring board and micarex are placed in respectively in lamp body, and be arranged on respectively on base, be evenly equipped with in the circuit board a plurality of straight cutting LED lamp pearls, two surfaces up and down of described micarex scribble respectively the silicone grease layer of insulating heat-conductive.

Wherein: described lamp body is inverted bowl-shape, and bowl is ring-type an end, and described base is fixed on lamp body at the bottom of as bowl; On described lamp body, fixed card is installed; Described fixed card is at least one group two, and two fixed cards of every group are with the Central Symmetry setting of described lamp body, and between line through the center of described lamp body; Described micarex and wiring board are setting up and down, and the bead weld of straight cutting LED lamp is connected on described wiring board, scribbles the silicone grease layer of insulating heat-conductive at the solder side of wiring board; The light emitting anger of described straight cutting LED lamp pearl is 8 degree, 15 degree, 30 degree or 45 degree.

Advantage of the present utility model and good effect are:

1. the utility model adopts little lighting angle, low power straight cutting LED lamp pearl, can adapt to different occasion requirements; Simultaneously, upper and lower two surfaces of micarex all scribble the silicone grease layer of insulating heat-conductive, have good heat-conducting effect.

2. the utility model is cancelled the diffusion shell of light source front, can avoid the decay to light by diffusion shell, has effectively improved actual illumination, reduces power consumption.

The accompanying drawing explanation

Fig. 1 is perspective view of the present utility model;

Fig. 2 is internal structure schematic diagram of the present utility model;

Wherein: 1 is lamp body, and 2 is straight cutting LED lamp pearl, and 3 is wiring board, and 4 is the silicone grease layer, and 5 is micarex, and 6 is screw, and 7 is base, and 8 is screw, and 9 is fixed card.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As shown in Figure 1 and Figure 2, the utility model comprises lamp body 1, wiring board 3, micarex 5 and base 7, and wherein lamp body 1 is inverted bowl-shape, and the bowl end is ring-type (the bowl end is empty), and base 7 is as being fixed on lamp body 1 by three screws 6 at the bottom of bowl.Wiring board 3 and micarex 5 are placed in respectively in lamp body 1, and micarex 5 and wiring board 3 are setting up and down, and on wiring board 3, uniform welding has the straight cutting LED lamp pearl 2 of a plurality of small-powers (0.066W), and the solder side of wiring board 3 scribbles the silicone grease layer 4 of insulating heat-conductive; Micarex 5 is as heat-conducting medium, and its upper and lower two surfaces scribble respectively the silicone grease layer 4 of insulating heat-conductive, can reduce thermal resistance, increase heat-conducting effect.The light emitting anger of straight cutting LED lamp pearl 2 can be 8 degree, 15 degree, 30 degree or 45 degree, and its colour temperature is from 2700K to 8900K.Micarex 5 and wiring board 3 are fixed on base 7 by screw 8.
