Description

The LED illuminating lamp

Technical field

The utility model relates to a kind of with the lighting bulb of LED as illuminator.

Background technology

Along with scientific and technological progress, LED is had a lot of scientific and technical personnel to develop the illuminating lamp as illuminator with LED because environmental protection, advantage such as energy-conservation apply on various lightings for this reason.

It as the patent No. 200620108050.2 Chinese patent " a kind of LED lighting bulb ", comprise base, Transparent lamp shade, LED group's mounting fixing parts, LED group and the control circuit formed by several LED, LED group's mounting fixing parts is formed by the some circuit boards system of enclosing, LED group installs and is distributed on each circuit board, this utility model is stitched together some circuit boards, increased the erection space of LED widely, installable LED quantity greatly increases, thereby strengthened the luminous intensity of bulb, the bulb luminosity that makes like this is big, can be used as lighting and be used for room lighting, its defective is that the circuit board that LED is installed is provided with too complexity in bulb, be unfavorable for manufacturing.

It as the patent No. 200620068319.9 Chinese patent " a kind of LED energy-saving stick-like bulb ", form by cylindricality barred body, light emitting diode, top cover and metab with positive and negative pin, light emitting diode is inserted on the cylindricality barred body, and the support of light emitting diode is connected with the positive and negative pin of metab by lead, the cylindricality barred body is nested on the metab, and top cover is fixedly mounted on cylindricality barred body top.The axle center that the light emitting diode single-column of this utility model is perpendicular to barred body to around radiative, rather than it is radiative to be parallel to the axle center, shape can become huge light beam when it gathers focus in reflector, throws light on or the effect of decoration thereby reach.It is inconvenient that its defective is that the LED pipe on the cylindricality barred body is connected with circuit, be unfavorable for manufacturing, and the LED that cylindricality barred body ring week distributes can only can not vertically give out light to luminous all around, also is unfavorable for throwing light on.

The utility model content

Technical problem to be solved in the utility model provides evenly effective LED illuminating lamp of a kind of manufacturing rational in infrastructure, easy, illumination.

The technical scheme of the utility model technical solution problem is such: a kind of LED illuminating lamp, it includes lamp socket and the bulb that is connected on the lamp socket, lamp socket inside is equipped with the circuit that civil power is transformed into LED element steady operation, there is the led circuit plate bulb inside, the polylith circuit board that it is characterized in that described fixed L ED element connects into lamp bracket in a circumferential direction, the design of lamp bracket upper end has condensing member, and the LED element is distributed on the surface of each circuit board.

As improvement, described LED element is the positive and negative that positioned opposite is mounted on circuit board, so that manufacture.

Preferably, described lamp bracket cross section presents the therefrom extraradial aplysia punctata of mind-set, and number is the 3-6 bar, and it is equally distributed to present circumference.

Further improve, described condensing member center arrangement has the slot that inserts for lamp bracket, and center on the lamp hole that the lamp bracket peripheral position has a plurality of cooperations, and be used for installing and fixing luminous LED element downwards, both be convenient to circuit board and installed and fixed, increased the LED pipe of penetrating light downwards again, improved brightness of illumination, that coupling collar week arranges, to around luminous LED pipe, reach downwards and to around luminous effect, and illumination basically relatively evenly, do not have tangible hot spot.

Preferably, described luminous LED element downwards is the other position of side that is arranged in circuit board.

Further improve, described lamp bracket lower end also is furnished with luminous LED element downwards, to improve brightness of illumination.

The improvement that is highly profitable, described bulb adopts the plastics bulb, and bulb internal surface is distributed with the convex lens to convex of being convenient to astigmatism, and light is played necessary uniformization effect.

Described lamp socket designs becomes standard-sized hickey or bayonet socket interface.

At last, described circuit board positive and negative is coated with reflector layer, plays necessary reflection action, improves illuminating effect.

Compared with prior art, advantage of the present utility model is: adopt special-shaped circuit board, being convenient to LED is arranged on the circuit board, adopt inserting slot construction, make circuit board be fixed in the bulb easily, structure is more reasonable, manufactures easily, and LED is distributed on the circuit board of lamp bracket circumferencial direction and under the condensing member, simultaneously can to around and give out light downwards, brightness of illumination is big, energy-conservation and light efficiency, effective, the reflector layer of combined circuit plate and the astigmat on the bulb, make equalizing light rays, essentially no hot spot, soft and not dazzling, be adapted at using on the bulb.

Fig. 3 is a bulb upward view of the present utility model.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Anticipate as Figure 1-3, a kind of LED illuminating lamp, it includes lamp socket 1 and the bulb 2 that is connected on the lamp socket, be equipped with in the lamp socket 1 civil power is transformed into the circuit 3 that the LED element carries out steady operation, and be arranged on LED element 4 in the bulb, and lamp socket 1 can adopt standard-sized hickey or bayonet socket interface, and these and traditional LED bulb are similar, the crucial part of its invention is to adopt the circuit board 5 of abnormity, exactly three circuit boards 5 is connected into the cross section and is The lamp bracket 6 of type, lamp bracket 6 cross sections present the therefrom extraradial aplysia punctata of mind-set, and be circularly and evenly distributed, LED element 4 is positive and negatives that positioned opposite is mounted on circuit board 5, circuit board 5 positive and negatives are coated with reflector layer, to improve brightness of illumination, the lower end of lamp bracket 6 is furnished with luminous LED element 7 downwards, LED element 7 is welded to connect with circuit board 5, plant and be fixed in the slot 9 at condensing member 8 centers in lamp bracket 6 upper ends, present embodiment is to adopt the cover form, condensing member 8 has the lamp hole 10 of three cooperations around the lamp bracket peripheral position, each lamp hole 10 is arranged in the other position of side of adjacent circuit plate, is mounted with luminous LED element downwards in each lamp hole 10, and LED is arranged on the angle line position of adjacent circuit plate.Condensing member 8 is fixed on lamp socket 1 lower end.Bulb 2 adopts the plastics bulb, and bulb internal surface is distributed with the convex lens to convex, and light is played astigmatism and uniformization effect.
