Description

LED-type christmes lamp bulb

The utility model relates to a kind of light-emitting diode (LED) formula christmes lamp bulb.

Christmas lamp is decorated use during Christmas Day in American-European various places, because good decorating effect, so widely the consumer selects the decorative lamp as setting for use, please cooperate consult shown in Figure 5, the element decomposing schematic representation of existing Christmas lamp, this Christmas lamp includes bulb 90, the lamp base of a fruit 92 and lamp socket 94, bulb 90 is to make with glass, its inside is provided with tungsten filament 900, extend pin 902 at bulb 90 1 ends, the lamp base of a fruit 92 is to be used to assemble bulb 90, after bulb 90 is located in being assembled to the lamp base of a fruit 92, the lamp base of a fruit 92 can be plugged and be assembled in the lamp socket 94, these lamp socket 94 ends extend electric wire 940, and it is used to transmit power, the existing quite long history of this type of Christmas lamp, multiple follow-on design though each relevant manufacturer has developed, the basic structure of osram lamp 90 did not still change.

Because above-mentioned existing christmes lamp bulb is perfect inadequately on structural design, still has many inconvenient parts in the use, such as:

1. power consumption

Because general Christmas lamp is all adopted osram lamp, the power consumption of such bulb is each 2.5～3.5 watts, suitable power consumption when a large amount of the use.

2. the misgivings that electric shock is arranged

Existing bulb uses for the user is convenient, so the employing power supply is 110 volts a AC power, this kind power supply is careless slightly promptly easily to cause the user to get an electric shock, and its fail safe is not enough.

3. glass bulb has broken possibility

Because existing osram lamp is all adopted glass material and made shell, the huge bulb of series quantity when making Christmans light string if it is promptly easily broken to bump, is hanging the possibility that the incised wound user is arranged when using.

4. useful life is short

Because the homogeneous phase in useful life of existing osram lamp is worked as limited, so make it after using once, may promptly have several bulbs in 1 year and not work and can't reuse, and after osram blows, also very rare people carries out maintain and replace, causes resource and waste economically.

Along with scientific and technological progress, people constantly develop new light-emitting component, in many light-emitting components of finishing newly developed, user mode with regard to Christmas lamp, the possibility that replaces with the LED bulb is the highest, but existing LED bulb can't meet the demand of Christmas lamp on making, so do not see have the Christmas lamp made from the LED bulb to come out so far as yet.

From existing LED bulb structure; it is to become the support 80 thick embryos that are paliform shown in Fig. 6 with the iron plate punching out earlier when making; form just being separately as shown in Figure 7 on this support 80 thick embryo tops; negative electricity extreme 82; 84; and make a ccontaining cup 840 with impact style more in addition at extreme 84 tops of negative electricity; carry out copper facing then in regular turn; nickel plating (protection copper; not make oxidation); copper facing; silver-plated four road galvanizing processes are to finish the processing of support 80; reduce impedance to increase conductivity; then can on support 80, carry out the installation of chip 86; it is the ccontaining cup 840 that earlier chip 86 welding is placed support 80 negative electricity extreme 84; then its brilliant line 860 is welded (as shown in Figure 8) mutually with positive electricity end 82; can insert support 80 in the mould bar (not shown) this moment; in the mould bar, pour into epoxy resin again; behind baking molding, the mould bar can be peeled off, at last support 80 punching presses be cut to finish the finished product of LED bulb.

It is that each is variant by each manufacturer is selected voluntarily that above-mentioned LED bulb is made flow process, yet principle that it used and made LED bulb are all similar, with regard to existing LED bulb manufacturing process and structure thereof, it also is not suitable for being used in the Christmas lamp aspect, and problem is:

1. equipment cost height

Existing support 80 adopts silver-plated step in electroplating flow process, though can improve the conductive effect of support 80, its equipment cost is quite high, can't contend with the equipment of producing traditional osram lamp.

2. material cost height

Existing chip 86 brilliant lines 860 are to make with the proof gold material, make material cost improve.

3. production cost height

Existing support 80 after being shaped with the iron plate punching out, the stamping press process of need arranging in pairs or groups in addition so that make a ccontaining cup 840 in the extreme 84 end face upper punches of negative electricity, this kind manufactured the increase of flow process, must cause production cost to improve.

4. the restriction of structural design

Because existing LED bulb is that chip 86 is placed in the ccontaining cup 840 of support 80 negative electricity extreme 84, so it only can be luminous towards the direction of ccontaining cup 840 openings, and can't be to lateral emitting, so can't be useful on the lamp string of Christmas lamp.Existing in addition LED bulb all is the bottom places that its chip 86 are placed in the LED bulb, if when being combined in it in lamp base of a fruit of Christmas lamp, its chip will inevitably be covered by in the lamp base of a fruit, can't reach the required luminous ornament effect of Christmas lamp at all.

The purpose of this utility model is to provide a kind of power saving, safety and life-span the long LED bulb that can be assembled into Christmas lamp.

The purpose of this utility model is to realize like this, a kind of LED-type christmes lamp bulb, this LED bulb can be arranged in pairs or groups the lamp base of a fruit and is assembled in the lamp socket that constitutes the lamp string, comprise positive electricity end in the LED bulb of making by the epoxy resin encapsulating and negative electricity is extreme, the extended pin of positive and negative electrode end then extends in LED bulb below, chip placing is on negative electricity is extreme, and brilliant line then is connected to positive electricity end.

Above-mentioned LED-type christmes lamp bulb, wherein, the LED bulb lower edge that epoxy resin constitutes just sets up the location that is assembled in the lamp base of a fruit, and pin then passes and bends 180 degree laterally behind the lamp base of a fruit and be attached to outside the lamp base of a fruit.

Above-mentioned LED-type christmes lamp bulb, wherein, chip placing is on the extreme end face of negative electricity.

Above-mentioned LED-type christmes lamp bulb, wherein, the position that chip is settled in the LED bulb is higher than the upper limb of the lamp base of a fruit.

Owing to adopted above-mentioned technical solution, a kind of LED-type christmes lamp bulb promptly is provided, it is welded on chip on the top of support, when chip is finished in epoxy encapsulation, the upper limb that highly surpasses the lamp base of a fruit, simultaneously it be with chip placing on the extreme top surface plane of negative electricity, so can be, and reach the demand of christmes lamp bulb by LED bulb lateral direction light emission.The utility model and traditional osram lamp are compared, and have following advantage: 1. adopt the direct current of low-voltage, improved safety in utilization; 2. each LED bulb only needs 2 volts voltage, reaches the power saving effect; 3.LED bulb adopts epoxy resin to make, and can avoid broken incised wound user; 4. chip is much longer than tungsten filament useful life, and can increase the useful life of lamp string.

Further specify architectural feature of the present utility model and purpose below in conjunction with accompanying drawing.
