Description

A kind of LED light source and the bulb adopting this light source to manufacture

Technical field

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

Background technology

Existing LED light source great majority all mount LED chip and are formed on the substrates such as aluminium base, TOP support, copper base, mainly there is following problem in this light source: 1, because substrate is to the obstruction of LED chip light transmition, cause light source luminescent angle little, make LED chip some light be subject to loss, reduce the luminous efficiency of light source; 2, the heat radiation of substrate to LED chip causes obstruction, makes the radiating effect of integrated light source bad, when utilizing this light source to make light fixture, generally all will consider supporting radiator, both limit the structural design of light fixture, improve again the manufacturing cost of light fixture.3, the dielectric voltage withstand characteristic of substrate is poor, causes the selection of driving power to be restricted, and finally cause the light fixture volume manufactured comparatively large, cost is high, and luminous efficiency is lower.

Summary of the invention

The technical problem to be solved in the present invention is to provide a kind of LED light source, and its lighting angle is large, good heat dissipation effect, and luminous efficiency is high, uniform in light emission, soft.

The present invention also provides a kind of bulb adopting this kind of LED light source to manufacture.

For achieving the above object, technical scheme of the present invention is: a kind of LED light source, comprise upper and lower 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 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 into adopt with plurality of LEDs chip respectively between lower glass substrate be connected in series or and two electrodes connecing rear formation be connected; Be surrounded by protector plate for glass above top glass substrate, below lower glass substrate, between above described protector plate for glass and top glass substrate, below lower glass substrate, scribble fluorescent material layer.

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

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

Preferably described two glass substrates are up and down square or hexagon.The expediently making of lower two glass substrates.

A kind of LED bulb adopting 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 lamp housing, LED light source is arranged in lampshade, and two outer electrodes of LED light source are connected with driving power by conducting element.

Further improvement, described LED light source is multiple through contacting or being connected with driving power by conducting element after parallel connection.The adjustment of bulb power can be facilitated.

Preferably described conducting element is wire.Adopt the wire of some strength to connect LED light source and driving power, effectively can improve assembly performance, reduce blocking light.

Beneficial effect of the present invention is as follows:

1, because the surrounding of LED chip adopts glass and transparent adhesive tape to encapsulate, the lighting angle of LED chip is not hindered, and the angle of its luminescence is large, and its lighting angle can close to 360 °;

2, the rising angle due to LED chip is large, correspondingly also improves its luminous efficiency;

3, due to above protector plate for glass and top glass substrate, below lower glass substrate, scribble fluorescent material layer between the side of upper lower glass substrate, the optical excitation fluorescent material that LED chip sends can improve uniformity and the mildness of its bright dipping greatly, reduces because of the luminous more dazzling problem of LED chip; This LED light source better can substitute the light sources such as incandescent lamp, Halogen lamp LED, electricity-saving lamp, has wide popularizing value;

4, due to high transmission rate, the high radiant rate of glass, the LED chip evolution of heat is dispelled the heat by radiation, its good heat dissipation effect;

5, because having good heat dispersion, utilize this LED light source manufacture light fixture time just without the need to supporting radiator, effectively can reduce the manufacturing cost of light fixture; In addition because glass has good dielectric voltage withstand characteristic, when making light fixture, its driving power can select the drive circuits such as isolation, non-isolated, AC/DC or DC/DC to drive, and just can improve the luminous efficiency of whole lamp, improve its safety in utilization simultaneously.
