Abstract

The utility model mainly discloses a surface light source for an indoor barrel lamp. The surface light source comprises an aluminum base plate, a fluorescent powder layer and silica gel wall glue. A luminous circuit is printed on the aluminum base plate, light-emitting diode (LED) chips are assembled on the aluminum base plate and are distributed to form an annular luminous area, the fluorescent powder layer is covered on the annular luminous area, and the silica gel wall glue is used for sealing the periphery of the fluorescent powder layer. The surface light source for the indoor barrel lamp is even in illumination, small in size and attractive and elegant in appearance and reduces cost.

Description

A kind of indoor Down lamp area source

Technical field

The utility model relates to lamp body component technology field, and is special relevant with a kind of indoor Down lamp area source.

Background technology

Traditional general fluorescent tube in Down lamp lamp source, volume is big, and cost is high, and fluorescent tube is revealed in the surface easily after installing.Along with the LED technical development, the LED light emitting diode has been adopted in a lot of lamp sources, and this structure is small and exquisite, and type is limited to but glow color receives diode, can't be widely used.So led chip is integrated with it, advantage efficiently, is more and more favored.So the inventor adopts led chip, design a kind of indoor Down lamp area source, this case produces thus.

The utility model content

The main purpose of the utility model provides a kind of indoor Down lamp area source, and light source light is according to even, and volume is little, and good looking appearance is generous, practices thrift cost.

In order to achieve the above object, the utility model is realized through following technical scheme:

A kind of indoor Down lamp area source comprises aluminium base, phosphor powder layer, silica gel enclosing wall glue; On aluminium base, be printed with illuminating circuit and be equipped with led chip, led chip distributes and forms annular light-emitting zone, covers phosphor powder layer on the annular light-emitting zone, around phosphor powder layer, adopts the silica gel enclosing wall adhesive edge.

Described illuminating circuit comprises cathode contact, cathode contact, circuit connecting wire, and circuit connecting wire picks out from cathode contact, and each led chip of connecting successively is connected to cathode contact at last.

Described led chip has 50.

Described aluminium base is circular, equidistantly offers the lamp socket installation position of 6 arcs in circular periphery, offers the lamp socket centre bore at circle centre position.

Described led chip is a blue led, and phosphor powder layer is yellow.

After adopting such scheme, the utlity model has many beneficial effects:

The utility model is encapsulated in led chip in the annular light-emitting zone, is coated by phosphor powder layer, constitutes whole Down lamp area source, and overall structure is simple, good looking appearance, and also annular light-emitting zone makes illumination patterns even.The blue light and the yellow fluorescent powder that send through led chip combine the back to form white light, and colour stable is effective.Series design is succinct, is applicable to large-scale industrial production.

Fig. 1 is the product appearance sketch map of the utility model preferred embodiment;

Fig. 2 is the aluminium base light-emitting zone printing figure of the utility model preferred embodiment;

Fig. 3 is an A-A generalized section among Fig. 1;

Fig. 4 is the circuit theory sketch map of the utility model preferred embodiment.

The specific embodiment

In conjunction with accompanying drawing, preferred embodiment explains further details to the utility model.

A kind of indoor Down lamp area source, as shown in Figure 1, comprise aluminium base 1, phosphor powder layer 2, silica gel enclosing wall glue 3.

Aluminium base 1 is the circuit substrate of the utility model, is circle, and diameter is 35mm, at the circle centre position lamp socket centre bore 11 that to offer a diameter be 4mm.On the circumferential edge of aluminium base 1, offer the lamp socket installation position 12 of 6 arcs that equidistantly distribute, lamp socket installation position 12 cooperates with lamp socket centre bore 11, can fast the utility model be assembled on the lamp socket.

As shown in Figure 2, led chip 4 distributes on aluminium base 1, forms the light-emitting zone 6 of an annular, has 50 led chips 4 in the present embodiment.Each led chip 4 all has 41, two the pin spliced eyes 42 in a lamp body installation position on aluminium base 1, during assembling, the lamp body of led chip 4 is positioned on the lamp body installation position 41, and two pins are plugged on the pin spliced eye 42.Illuminating circuit comprises cathode contact V+, cathode contact V-, and some circuit connecting wires 5.From cathode contact V+, circuit connecting wire 5 with 4 series connection of 50 led chips, finally is connected to cathode contact V-again successively, and its circuit theory diagrams are as shown in Figure 4.The annular light-emitting zone 6 that forms of led chip 4 helps light and is evenly distributed like this.

At light-emitting zone 6 surface coverage layer of fluorescent powder layers 2, the led chip 4 that adopts in the present embodiment is blue led, produces blue light, and phosphor powder layer 2 adopts yellow fluorescent powder to form, and blue light and yellow fluorescent powder combine the back to produce white light like this, make illumination bright stable.

Phosphor powder layer 2 neighborings all coat a circle silica gel enclosing wall glue 3, adopt silica gel material that phosphor powder layer 2 is enclosed the limit and coat.

The foregoing description only be used to explain inventive concept of the utility model, but not to the qualification of the utility model rights protection allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should fall into the protection domain of the utility model.
