Description

A kind of novel led light source and the bulb that adopts this light source to make

Technical field

The present invention relates to novel led light source, especially a kind of novel led light source the invention still further relates to the LED bulb that adopts this Novel LED light source.

Background technology

Existing led light source great majority all mount led chip at aluminium base, TOP support, copper base etc. and form above the substrate, mainly there is following problem in this light source: 1, owing to the obstruction of substrate to the led chip light transmition, cause the light source luminescent angle little, make led chip part light be subject to loss, reduce the luminous efficiency of light source; 2, substrate causes obstruction to the heat radiation of led chip, so that the radiating effect of integrated light source is bad, when utilizing this light source to make light fixture, generally all will consider supporting radiator, has both limited the structural design of light fixture, improves again the manufacturing cost of light fixture.3, the dielectric voltage withstand characteristic of substrate is relatively poor, causes the selection of driving power to be restricted, and the light fixture volume that finally causes manufacturing to finish is larger, and cost is high, and luminous efficiency is lower.

Summary of the invention

The technical problem to be solved in the present invention provides a kind of novel led light source, and its lighting angle is large, good heat dissipation effect, and luminous efficiency is high, and bright dipping is even, soft.

The present invention also provides a kind of bulb that adopts this kind led light source to make.

For achieving the above object, technical scheme of the present invention is: a kind of novel led light source, comprise up and down two glass substrates, two outer electrodes, between upper lower glass substrate, with transparent glue seal one or plurality of LEDs chip are housed, when the led chip of described encapsulation is one, two outer electrodes stretch between the lower glass substrate and are connected with two electrodes of led chip respectively, when the led chip of described encapsulation is many, two outer electrodes stretch between the lower glass substrate respectively with the plurality of LEDs chip adopt serial connection or and two electrodes connecing rear formation be connected; Be surrounded by protector plate for glass below top, the lower glass substrate of top glass substrate, scribble fluorescent material layer between top, the lower glass substrate of described protector plate for glass and top glass substrate following.

Further improve, the side of described upper lower glass substrate also is surrounded by protector plate for glass, and the part of two outer electrodes is in outside the protector plate for glass.The junction, edge can adopt transparent adhesive tape to be connected between each protector plate for glass, improves the bonding strength of protector plate for glass.

Further improve again, also scribble fluorescent material layer between the side of described protector plate for glass and upper lower glass substrate.Further improve the soft property of light source bright dipping.

Preferred described up and down two glass substrates are square or hexagon.The convenient up and down making of two glass substrates.

A kind of LED bulb that adopts above-mentioned led light source, comprise lamp holder, lamp housing, driving power, led light source, lampshade, lamp holder is fixed on the top of lamp housing, lampshade is fixed on the bottom of lamp housing, driving power is contained in the lamp housing, led light source is arranged in the lampshade, and two outer electrodes of led light source are connected with driving power by conducting element.

Further improve, described led light source is a plurality ofly to be connected with driving power by conducting element after series winding or parallel connection.Can make things convenient for the adjustment of bulb power.

Preferred described conducting element is wire.Adopt the wire of some strength to connect led light source and driving power, but the Effective Raise assembly performance reduce blocking light.

Beneficial effect of the present invention is as follows:

1, owing to adopting glass and transparent adhesive tape to encapsulate around the led chip, the lighting angle of led chip is not hindered, and its luminous angle is large, and its lighting angle can be near 360 °;

2, because the rising angle of led chip is large, corresponding its luminous efficiency that also improves;

3, owing to scribble fluorescent material layer between the side of following, the upper lower glass substrate of top, the lower glass substrate of protector plate for glass and top glass substrate, the optical excitation fluorescent material that led chip sends can greatly improve it and go out uniformity of light and soft property, reduces because of the luminous more dazzling problem of led chip; This led light source is the light sources such as replace incandescent, Halogen lamp LED, electricity-saving lamp better, have wide popularizing value;

4, owing to high transmission rate, the high radiant rate of glass, the led chip evolution of heat can be dispelled the heat by radiation, its good heat dissipation effect;

5, because having preferably heat dispersion, just need not supporting radiator when utilizing this led light source to make light fixture, can effectively reduce the manufacturing cost of light fixture; Because glass has preferably dielectric voltage withstand characteristic, its driving power can select the drive circuits such as isolation, non-isolation, AC/DC or DC/DC to drive when making light fixture in addition, just can improve the luminous efficiency of whole lamp, improves simultaneously its safety in utilization.
