Description

A kind of desk lamp area source

Technical field

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

Background technology

Traditional desk lamp lamp source is generally bulb or fluorescent tube, and volume is big, can't be applicable to the miniaturization production application.Along with the LED technical development, a lot of desk lamps adopt the LED light emitting diode, and this structure is small and exquisite, and type is limited to but glow color receives diode, can't be widely used.Along with the LED technical development, led chip is more and more ripe, so the inventor adopts led chip, designs a kind of desk lamp area source, and this case produces thus.

The utility model content

The main purpose of the utility model provides a kind of desk lamp area source, and volume is little, and light source colour is stable, and is simple in structure, easy to process.

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

A kind of desk lamp area source comprises aluminium base, phosphor powder layer, silica gel enclosing wall glue; On aluminium base, print illuminating circuit and be equipped with led chip, cover phosphor powder layer on the aluminium base, around phosphor powder layer, adopt the silica gel enclosing wall adhesive edge.

Described illuminating circuit comprises that the parallel led chip that distributes alternately pastes unwrapping wire and led chip pin line, and led chip pastes and is placed on the led chip subsides unwrapping wire, and the pin of led chip is connected on the led chip pin line.

Described led chip is divided into some series connection group, and some series connection group is connected in parallel.

Described series connection group comprises 5 led chips series connection, and the tie point of adjacent LED chip series connection is connected across on the same led chip pin line.

Described series connection group one has 16 groups.

The anodal led chip pin line that connects of described series connection group is the anodal track of illuminating circuit, and the led chip pin line that series connection group negative pole connects is the negative pole track of illuminating circuit.

Described phosphor powder layer is that yellow fluorescent powder forms.

Described led chip is a blue led.

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

The utility model is encapsulated in led chip on the illuminating circuit, is coated by phosphor powder layer, constitutes whole desk lamp area source, and overall structure is simple, and 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.Luminous resistance connection in series-parallel design is succinct, is applicable to large-scale industrial production.

The specific embodiment

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

A kind of desk 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, and long 108mm, wide 34mm, illuminating circuit are printed on this plate, and be as shown in Figure 2.Illuminating circuit is mainly wherein in light-emitting zone 11; The size of light-emitting zone 11 is long to be 80mm, and wide 20mm has 5 led chips and pastes unwrapping wire 12; Article 6, led chip pin line 13; Led chip pastes unwrapping wire 12 and led chip pin line 13 parallel distributing alternately, outmost wherein anodal track that led chip pin line 13 is whole illuminating circuit, and another led chip pin line 13 is the negative pole track of whole illuminating circuit.Employed led chip 4 is 80 altogether in the present embodiment, is divided into 41 parallel connections of 16 series connection groups and constitutes, and each series connection group 41 is formed by 4 series connection of 5 led chips, and schematic diagram is as shown in Figure 4, and the LED both positive and negative polarity is the first to link to each other.Correspond on the illuminating circuit, it is to mount led chip 4 that all led chips paste on unwrapping wire 12, and led chip pin line 13 is to be used to peg graft the pin of led chip 4.16 series connection groups 41 on led chip 4 series connection points arrange in the illuminating circuit equal intervals, help light and are evenly distributed.

The light-emitting zone 11 surface coverage layer of fluorescent powder layers 2 of aluminium base 1; 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; Blue light and yellow fluorescent powder combine the back to produce white light like this, are applicable to the desk lamp light source.

Coat a circle silica gel enclosing wall glue 3 around the phosphor powder layer 2, 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.
