Description

A kind of Novel LED light

Technical field

The utility model relates to field of light fittings, a kind of specifically LED lamp.

Background technology

The conditional electronic electricity-saving lamp is called Electricity-saving lamp bulb, electronics bulb, compact fluorescent lamp and integral type fluorescent lamp again, is meant the lighting apparatus that fluorescent lamp is become an integral body with ballast combinations.The size and the incandescent lamp of electricity-saving lamp are close, and the interface that connects with lamp socket is also identical with incandescent lamp, so can directly replace incandescent lamp.This light source only need expend 1/5 to 1/4 of ordinary incandescent lamp power consumption, thereby can save a large amount of illumination electric energy and expense under the prerequisite that reaches same luminous energy output, therefore is called as electricity-saving lamp.Because of the support policy of country in early stage, extensive use in civilian household and general commercial lighting at present.Because electricity-saving lamp is the same with sight lamp luminescence principle, fluorescent lifetime is short, the shortcoming of not environmental protection so all exist, though saved electric energy, needs often to change lamp, oppositely causes energy waste.

The LED lamp is a kind of light fixture that developed rapidly in recent years, has energy-saving advantages more, and the stable performance of LED lamp pearl, will grow with respect to fluorescent lifetime.But because the maximum lighting angle of LED is 120 degree, normally be made into the fluorescent tube form, so also just limited the scope of application of LED lamp, the LED lamp can't be popularized.

In LED luminescence technology progressively ripe today, the LED corn ear type lamp that substitutes electronic energy-saving lamp has been born.Corn ear type LED lamp is a kind of of LED light fixture, because the maximum lighting angle of LED is 120 degree, in order to make its 360 degree luminous, its shaped design is become subcylindrical, as the corn ear form, so be called LED corn ear lamp.And its interface with lamp socket is identical with existing electricity-saving lamp, so can substitute electricity-saving lamp fully.

Form but the LED corn ear type light fixture (as shown in Figure 1) of prior art generally is inserted in the special draw-in groove of lamp housing by 6～12 slice wiring boards that are welded with the lamp pearl, whole light fixture profile is hexagon or octagon or dodecagon.Be electrically connected between wiring board with lead and connect the assembling complexity.Very most surfaces is long-pending because the special-purpose draw-in groove of lamp housing has taken, so lamp body luminescence window utilization rate is not high.And because the lamp column pitch is bigger, and the luminous angle of LED is 120 degree to the maximum, although the mode that adopts light fixture to add lampshade is carried out optical distribution one time, but still is difficult to reach light fixture ambient light effect of uniform.

This type of LED lamp is also comparatively complicated on manufacture craft in addition, needs during making light fixture integral body is assembled and welded.Can't replace with machine under the manual situation of producing of people at most of parts, single light fixture production cycle is long, and production cost is higher, and because manual production can't guarantee uniformity in product performance.

Moreover the shape and the structure of lamp also are restricted, and can only be designed to the corn ear type, and shape is too single, do not meet the modern and pursue requirement changeable, aesthetic feeling.

In order to overcome above-mentioned defective, the someone has found out a lot of diverse ways, but all because of structure too complexity be not suitable for volume production and can't be used more widely.

The utility model content

In order to address the above problem, the utility model embodiment provides a kind of batch machining, the process-cycle is short, uniformity is stable LED lamp be convenient to.

The utility model is achieved in that

A kind of LED lamp comprises LED lamp pearl, driving power, wiring board, and wiring board is electrically connected with driving power, and described wiring board is a flexible print circuit board, and described LED lamp pearl, electronic component are integrated on the flexible print circuit board.

Optionally, described LED lamp also comprises lampshade, lamp tube and base, and described base is a hickey, and the base top is provided with the lamp tube, in the lamp tube driving power is set, and the flexible print circuit board volume pastes and is fixed on lamp tube periphery, and described lampshade covers on lamp tube outside.

Further, described LED lamp pearl series connection is integrated on the flexible print circuit board.Use the place of lamp to need the brightness unanimity of lamp at some, can adopt the mode of series lamp pearl this moment, connects the electric current unanimity that can guarantee by each lamp pearl in the mode of connecting, thereby guarantee each lamp pearl brightness unanimity.

Further, in the described driving power liquid-magnetism filled transformer is set.Adopt this power supply can reduce thermal discharge, reliability is higher, is more suitable in driving high voltage-small current LED lamp.

Further again, described lamp tube adopts aluminium to make, and described lamp tube is made up of a hollow cylinder and a round bottom that is arranged on the cylinder bottom, and the round bottom diameter is greater than lamp tube disc diameter.Adopt aluminium to make and can improve radiating efficiency better, flexible print circuit board is delivered to the heat that LED lamp pearl produces on the aluminium lamp tube, dispels the heat, and protection LED lamp pearl and wiring board avoid overheated, increase the service life.

Optionally, described LED lamp comprises that also an inside is empty cube shaped lamp tube, and described driving power is arranged in the lamp tube, and described flexible print circuit board is around the outer surface that is fixed on cube shaped lamp tube.

Optionally, described LED lamp also comprises the lamp tube of an inside for empty sphere, and described driving power is arranged in the lamp tube, and described flexible print circuit board is around the outer surface that is fixed on the globe lamp tube.

The LED lamp that the utility model provides adopts flexible print circuit board, flexible printed circuit board (FPCB:Flexible Printed Circuit Board) is the printed circuit made from flexible insulating substrate, has the advantage that many rigid printed circuit boards do not possess.For example it can free bend, coiling, folding, can require to arrange arbitrarily according to space layout, and move arbitrarily and flexible, thereby reach integrated that the components and parts assembling is connected with lead at three dimensions.Utilize FPCB can dwindle the volume of electronic product greatly, be suitable for the needs that electronic product develops to high density, miniaturization, highly reliable direction.In addition, FPCB also has good thermal diffusivity and solderability and is easy to advantages such as load, integrated cost be lower.The bead weld of LED lamp is connected on the flexible print circuit board, and there is not the not high problem of luminescence window utilization rate in (1), makes that the light fixture ambient light is even; (2) outward appearance can be changeable, can be cube, sphere, cylindrical, also can be the arc of various designs, need not the combination of many group rigidity wiring boards, the light source that can finish on the various planes is laid, satisfy the modern and pursue changeable, as to pursue aesthetic feeling requirement, solve the single problem of shape in the prior art; (3) this material can increase copper pad, can cover on the various light fixture modules surface after making its torch pearl.

The LED lamp that the utility model provides has the following advantages:

(1) image appearance is changeable, and is attractive in appearance;

(2) aspect cost, flexible print circuit board is suitable substantially with rigidity wiring board price, and material cost does not almost have increase, but flexible print circuit board is fit to the mechanization batch machining, and production cost significantly reduces;
