Abstract

The utility model provides an omnidirectional light-emitting LED bulb which settles the following problems in the prior-art omnidirectional LED bulb: complicated structure, many troubles in mounting, etc. The omnidirectional light-emitting LED bulb comprises a heat radiating housing and an LED light source. The heat radiating housing is provided with a lamp base. The LED light source is provided on the lamp base. The LED light source comprises two brackets and an LED chip. The brackets heads of the two brackets are placed in a silicone lens and are integrally packaged. An upper part of the silicone lens is a spherical surface. Two corresponding side surfaces of the brackets heads are respectively provided with an LED chip. The LED chips correspond with the silicone lens. The LED chips of the two brackets on a same side surface are connected through a wire. The LED chips of the same side surface enlarge a light-emitting surface and simultaneously enlarge a half-intensity angle. The LED chips of the corresponding side surfaces can provide approximate 360 DEG omnidirectional irradiation. The top light is provided by a plurality of chips of the side surfaces of the brackets, thereby effectively improving the top light intensity. Furthermore the omnidirectional light-emitting LED bulb has the following advantages: simple structure and low manufacturing cost.

Description

The omnibearing luminous LED bulb

Technical field

The utility model relates to a kind of omnibearing luminous LED bulb.

Background technology

Along with the high speed development of LED technology, LED becomes the first-selection of novel green illumination gradually with advantages such as its energy-saving and environmental protection.The LED bulb of using for room lighting, to the basic demand of its light intensity distributions and brightness be: bulb is luminous not only will to possess isotropic directivity, and light distribution will be tried one's best evenly.As everyone knows, LED lamp source is owing to encapsulate, and its light-emitting area is 180 degree to the maximum, and half-intensity beam angle generally is to the maximum about 140 degree.Mostly present LED bulb is board-like LED integration module light source is implanted in the bulb, can't realize omnibearing luminous.The patent No. is that 200920206369.2 Chinese patent discloses " a kind of bulb lamp ", though can realize luminously than wide-angle, complex structure is arranged, shortcomings such as contact-making surface is many, making is difficult, radiating effect difference.Application number is that 2010146167.0 Chinese invention patent application discloses " can improve the LED bulb lamp of light transmittance "; Ball bubble tail end luminous flux is few, does not reach comprehensive requirement, also exists complex structure to make difficulty simultaneously; Shortcomings such as radiating effect is poor, and service life is short.

Summary of the invention

For overcoming problem in the background technology, the utility model provides a kind of simple in structure, omnibearing luminous LED bulb of being convenient to install.

The technical scheme of the utility model is: a kind of omnibearing luminous LED bulb; Comprise radiating shell and LED lamp source, said radiating shell is provided with lamp socket, and described LED lamp source is located on the lamp socket; It is characterized in that: described led light source comprises 2 supports and led chip; The bracket head of 2 supports is deployed in silica-gel lens and the one encapsulation, and the top of described silica-gel lens is sphere, and two corresponding side surface of said support head are equipped with led chip; Said led chip is corresponding with silica-gel lens, and the led chip of said 2 supports on the same side is connected through circuit.

As a kind of improvement of the utility model, be provided with 2 groups of led light sources on the described lamp socket at least.

Another kind as the utility model improves, and 2 supports on the described led light source are fixed by fixed mount in mid-stent.

The beneficial effect of the utility model is; The led chip of same side has not only increased light-emitting area, and has increased half-intensity beam angle, and the led chip of corresponding side surface then can provide the comprehensive irradiation that is close to 360 degree; Because being a plurality of chips of cradle, the light at top provides; Strengthened the luminous intensity at top effectively, and the utility model is simple in structure, makes, processing cost is low.
