Description

The omnibearing luminous LED light source

Technical field

The utility model belongs to the led light source technical field, particularly relates to a kind of omnibearing luminous LED light source.

Background technology

Along with development of science and technology, advantage such as the LED lamp relies on the high and low power consumption of luminous efficiency, long-life, do not need high pressure, safe, light intensity even photochromic is easy to modulation is applied in various lighting fields widely and is used for replacing incandescent lamp and electricity-saving lamp.But incandescent lamp and electricity-saving lamp still have than cross the advantage of present most of LED, are that they can comprehensive bright dipping, have superiority in convenience and the practicality used.The light emission direction of most of LED lamps is limited, has any different with incandescent lamp and electricity-saving lamp, promptly brings limitation to practicality, also makes the LED lamp be difficult to directly substitute incandescent lamp and the electricity-saving lamp that in lighting, has used.

The utility model content

Little in order to solve prior art LED lamp lighting angle, light emission direction is limited, gives the actual problem of bringing limitation of using, and the utility model provides a kind of increase lighting angle, can realize omnibearing luminous omnibearing luminous LED light source.

In order to address the above problem, the technical scheme that the utility model is taked is:

A kind of omnibearing luminous LED light source; Comprise flexible circuit board, positive emitting led chip or lamp pearl; Flexible circuit board is provided with conductive pattern; On the positive or tow sides of conductive pattern, be reserved with the land; It is characterized in that: also comprise side-emitting LED chip or lamp pearl, said flexible circuit board bends to axisymmetric curved surface thin slice light source, and positive emitting led chip or lamp pearl are installed on the land of axisymmetric curved surface thin slice light source middle part; Said upwards side-emitting LED chip or lamp pearl be installed on the land of axisymmetric curved surface thin slice light source top, light source is equipped with downward side-emitting LED chip or lamp pearl on the following land.

Aforesaid a kind of omnibearing luminous LED light source is characterized in that: said axisymmetric curved surface thin slice light source is cylinder light source or polygon light source.

Aforesaid a kind of omnibearing luminous LED light source is characterized in that: said polygon light source is triangle, quadrangle, hexagon, octagon.

Aforesaid a kind of omnibearing luminous LED light source is characterized in that: said flexible circuit board thickness is between 0.08mm-0.2mm.

Aforesaid a kind of omnibearing luminous LED light source is characterized in that: said axisymmetric curved surface thin slice light source bottom is drawn lead and is connected with power supply.

Aforesaid a kind of omnibearing luminous LED light source is characterized in that: the said transparent outer cover that outside axisymmetric curved surface thin slice light source, is connected with.

Aforesaid a kind of omnibearing luminous LED light source, it is characterized in that: said transparent outer cover top and bottom are provided with hollow out or reticulated, open, and the space that surrounds with axisymmetric curved surface thin slice light source forms air duct.

The beneficial effect of the utility model is;

1, the utility model axisymmetric curved surface thin slice light source inside does not connect heat sinkly, and radiator, led array directly and the inner air heat loss through convection have alleviated weight, have reduced cost, have improved radiating effect, have improved light-emitting area

2, the utility model led array uses positive emitting led chip or lamp pearl; But the bottom and upper segment at cylinder light source or polygon light source uses side-emitting LED chip or lamp pearl; Make whole luminous existing intersect at axial luminous; Also there is to be parallel to the luminous of axle the luminous illuminator that forms comprehensive Space Angle that combines of two kinds of led chips or lamp pearl.

3, positive emitting led chip of the utility model or lamp pearl all are that the bottom is connected with power supply through lead with side-emitting LED chip or lamp pearl, do not change whole plate encapsulation or paster mode, have reduced the difficulty of processing.

4, the utility model connects transparent outer cover in the axisymmetric curved surface thin slice light source outside.Transparent outer cover protection illuminator, simultaneously transparent outer cover provide once or repeatedly optical transform eliminate LED point light source light-emitting characteristic and change led array light source visual effect.

5, the utility model uses flexible circuit board to carry out the curved surface bending, connects at intersection, accomplishes the connection of axisymmetric curved surface thin slice light source, and the curved surface handing-over can be used fixing means such as welding, gummed, machinery, processes very convenient.
