Description

A kind of omnibearing luminous LED lamp

Technical field:

The utility model relates to the LED product technical field, is meant a kind of omnibearing luminous LED lamp especially.

Background technology:

As everyone knows, traditional incandescent lamp energy consumption is higher, and energy utilization rate is very low, has probably only become luminous energy less than 1/10th energy, and other all is heat energy being wasted in vain.So people are trying every possible means to come replace incandescent with new light source always.Therefore, electricity-saving lamp has just arisen at the historic moment.Because Comparatively speaking it cheaply make well again, so just obtained a large amount of application, the trend that progressively replaces incandescent lamp arranged.Electricity-saving lamp is to adopt the electron excitation principle luminous, and with respect to incandescent lamp, electricity-saving lamp has the advantage of power saving.But the shortcoming that electricity-saving lamp exists is exactly: contain mercury in the electricity-saving lamp, mercury has been intermediation in power saving fluorescent lamps, does not have the hydrargyrum energy-saving lamp just can not be luminous.Just caused in the electricity-saving lamp production process and use mercury pollution is arranged after discarded like this, in addition, electricity-saving lamp is still glassware, and is easily broken, bad transportation, bad installation.Secondly, its power consumption is still bigger.At last, electricity-saving lamp damages easily, and the life-span is short.

And the developing direction of energy-saving illumination apparatus is exactly the LED light fixture at present.With respect to above-mentioned lighting, the LED light fixture has following advantage:

1, energy-conservation.The energy consumption of white light LEDs only is 1/10 of an incandescent lamp, 1/4 of electricity-saving lamp.

2, long service life.The life-span of LED lamp can reach and be higher than incandescent lamp and electricity-saving lamp more than 100,000 hours far away.

3, can frequent starting.Very fast the breaking down if traditional electricity-saving lamp, frequent startup or the shutoff of incandescent lamp, filament will be turned black, and the LED lamp can not.

4, solid-state encapsulation belongs to the cold light source type, so its easily transportation and installing can be afraid of vibration by device in the equipment of any miniature and sealing, does not need to consider heat radiation basically.

5, environmental protection does not have the harmful substance of mercury.The very easily dismounting of the assembling parts of LED lamp, it is convenient to reclaim.

Based on These characteristics, the LED lamp will progressively replace other lightings.But also there is certain defective in the LED lamp: have a very strong directionality because led chip is luminous, what it illuminated is regional limited, and does not think that the light source of incandescent lamp, electricity-saving lamp disperses.The described LED lamp is applied in the normal lighting just need address this problem.Common settling mode is in the Luminous lamp holder of a light fixture plurality of LEDs to be installed at present, and the direction that every LEDs is corresponding different so forms the light of dispersing.The shortcoming of this mode is apparent: the cost height because lamp holder need be installed a plurality of LED, makes the assembling process complexity.This shows that this settling mode does not solve the omnibearing luminous problem of LED only for curing the symptoms, not the disease from the source.

The utility model content:

Technical problem to be solved in the utility model is exactly the deficiency that exists in the present LED lamp product in order to overcome, a kind of omnibearing luminous LED lamp is proposed, this LED lamp is luminous to all angles by the led chip inside encapsulation, that be 360 degree angular distribution, overcomes the luminous deficiency with directionality of traditional LED lamp.

For solving the problems of the technologies described above, the utility model has adopted following technical scheme: this omnibearing luminous LED lamp comprises support and is encapsulated in led chip on the support, described support has an encapsulation platform, a most led chip are uniformly distributed in around the encapsulation platform with 360 degree, and packed resin-encapsulated.

Described encapsulation platform upper surface also is fixed with led chip.

Described support comprises: main body and fixing with main body and the probe of mutually insulated, described main body is made of encapsulation platform and thread segment, and in main body, form the through hole of perforation, described probe comprises: needle body and the end that takes shape in needle body one end, needle body inserts from the opening that encapsulates the platform top, and is stretched out by the opening of thread segment.Wherein thread segment is used for the utility model is installed in the corresponding interface of light fixture, to realize Fast Installation.And thread segment and needle body are connected with power electrode in the interface respectively, are the led chip power supply.

Described encapsulation platform comprises: boss, be positioned at the cylinder at boss center, wherein the cross section of cylinder is a regular polygon, is distributed with a led chip in each side of cylinder.

The end of described probe is positioned at the top of cylinder, and is provided with felt pad between end and the cylinder top, is filled with insulant in the pipeline of the rack body that the confession needle body inserts, and makes between main body and the probe by insulant and felt pad and insulating.

The boss surface of described encapsulation platform is center height, low awl inclined-plane all around.

A described led chip wherein contact conductor is fixed on the encapsulation platform, and its another contact conductor is fixed on the end of probe.

Described led support surface gold-plating is beneficial to the welding of LED contact conductor like this and improves conductive effect.

The utility model is to have encapsulated a plurality of led chips in a LED, and these chips are 360 ° of distributions, can realize omnibearing luminously, overcomes the luminous shortcoming with directionality of LED in the present product.The utility model can be widely used in the various lightings, present relatively LED light fixture, and it is little that it has a volume, wide, the easy for installation plurality of advantages of illumination orientations.
