Abstract

The utility model provides a substrate chip light source. The substrate chip light source comprises a substrate and a plurality of LEDs (light emitting diode) arranged on the substrate, wherein the plurality of LEDs are distributed on the substrate in a ring shape to form a ring-shaped lighting area. The substrate chip light source can avoid area reduction of the lighting area, reduce the dark area, solve the problems of strong middle illumination intensity and small illumination angle and significantly improve the illumination effects of a bulb lamp. The utility model also provides a 6CE1 bulb lamp with the substrate chip light source.

Description

A kind of bulb lamp and chip on board light source thereof

Technical field

The utility model relates to electrical lighting equipment technical field, more particularly, relates to a kind of chip on board light source, and the utility model also relates to a kind of bulb lamp with above-mentioned chip on board light source.

Background technology

Bulb lamp is the Novel energy-saving lamp that substitutes conventional incandescent bulb, along with the abbreviation of the English Light-Emitting Diode of LED(, light emitting diode) the high speed development LED bulb lamp of technology becomes the only choosing of novel green illumination gradually.

Bulb lamp is by chip on board (English name Chip On Board, being COB) light source realizes luminously, and COB light source comprises substrate 01 and is arranged on the LED on substrate, and wherein a plurality of LED are gathered in the centre of substrate, form circular luminous district 02, as shown in Figure 1.But, because this circular luminous district 01 is full circle light-emitting area, the light that this circular luminous district 02 sends is due to the light wave characteristic of light itself, light can be assembled to the center line near irradiation area at irradiation area, there is optically focused, near high light center line has stopped that light passes center line and propagates, thereby the degree of distributing of light is weakened, and then reduced the area of irradiation area, to such an extent as to cause the bulb lamp field of illumination made from this kind of COB light source little, leave the phenomenon of compare great dark space 03, as shown in Figure 2, had a strong impact on the illuminating effect of bulb lamp.

Therefore, how to improve COB light source intermediate light intensity strong, the problem that lighting angle is little, is current those skilled in the art's problem demanding prompt solution.

Utility model content

In view of this, the utility model provides a kind of chip on board light source, and it is strong that it can improve self intermediate light intensity, the problem that lighting angle is little.The utility model also provides a kind of bulb lamp with above-mentioned chip on board.

In order to achieve the above object, the utility model provides following technical scheme:

A light source, comprises substrate and is arranged on a plurality of light emitting diodes on substrate, wherein, a plurality of described light emitting diodes are circular distribution to form circular light-emitting zone on described substrate.

Preferably, in above-mentioned chip on board, be positioned in the described central substrate at described circular light-emitting zone center and be provided with cable-through hole, locating hole and pad.

Based on the above-mentioned chip on board providing, the utility model also provides a kind of bulb lamp, comprises chip on board and lampshade, and described chip on board is chip on board described in above-mentioned any one.

In the chip on board that the utility model provides, all light emitting diodes on substrate with circular formal distribution, thereby form annulus luminous zone.Due to the center of annulus luminous zone emission of light not, when so the light that send this annulus luminous zone is assembled to the center line near irradiation area in irradiation area, can there is not optically focused phenomenon, light can continue to propagate, disperse through this center line, thereby avoided reducing of field of illumination area, dark space area has obtained reducing, solved self intermediate light intensity strong, the problem that lighting angle is little, has significantly improved the illuminating effect of bulb lamp.The utility model also provides a kind of bulb lamp with above-mentioned chip on board.
