Abstract

The utility model discloses a novel blue-light LED (light emitting diode) illuminating lamp, relating to the technical field of LED illumination. The novel blue-light LED illuminating lamp is provided with a spherical lampshade and a lamp holder which is in smooth connection with the lamp holder, wherein a driving power supply and heat radiators are arranged in the lampshade, each blue-light LED is fixedly arranged on each heat radiator and is provided with a plastic bracket, a blue-light chip is arranged in each plastic bracket, each blue-light chip is connected with a pin of each blue-light LED through a gold wire, the driving power supply is connected to the pins, the plastic bracket of each blue-light LED is filled with transparent plastic glue, and the inner wall of the lampshade is coated with a fluorescent powder coating in a spraying manner. The novel blue-light LED illuminating lamp has the beneficial effects of greatly improving the luminous efficiency, ensuring that the blue-light chips can sufficiently dissipate heat because no fluorescent powder is coated on the blue-light chips, simplifying the product design because no complex power circuit and heat dissipation mechanism is needed, reducing the production cost and prolonging the service life.

Description

A kind of novel blue light LED lighting

[technical field]

The utility model relates to the LED lighting technical field, and in particular, the utility model relates to a kind of novel blue light LED lighting.

[background technology]

The LED bulb lamp is as the first-selected product of next generation's illumination, and itself has energy-conserving and environment-protective, long service life, light efficiency high.But high first installation cost has limited its scope of application, to such an extent as to also there is not now the large-area lighting of home field that enters.

With reference to shown in Figure 1, what traditional LED light fixture adopted is the white light LEDs of large power white light LED or multi-chip package, their structure all is first blue chip 1 to be fixed on the support 2, stamp after the gold thread 3, in the cup chamber of support 2, fill yellow fluorescent powder 4, perhaps sprayed with fluorescent powder on blue chip 1 encapsulates in the conventional mode again.Exactly above-mentioned packaged LED particle is welded on the aluminium base in the design of LED light fixture, is assembled into the LED light fixture after adding radiator, power supply, lampshade.May there be some problems in this traditional light fixture, comprises lamp locker aberration, blackening, heating inequality, complex structure etc., still haves much room for improvement.

[utility model content]

The purpose of this utility model is effectively to overcome the deficiency of above-mentioned technology, provides a kind of and can improve luminous efficiency, the novel blue light LED lighting that radiating effect is good, this light fixture can be simplified the design of product, lowered production cost, and reliability is strong, long service life.

The technical solution of the utility model be achieved in that it have spherical lampshade and with the lamp holder of lampshade smooth connection, in described lampshade, be provided with driving power and radiator, be fixed with blue-ray LED on the radiator, this blue-ray LED has plastic stent, be provided with blue chip in the plastic stent, and this blue chip is connected with the pin of blue-ray LED by gold thread, driving power is connected on the pin, its improvements are: be filled with transparent plastic packaging glue in the plastic stent of described blue-ray LED, be coated with fluorescent coating on the inwall of described lampshade;

In the said structure, described blue-ray LED also has a heat radiation substrate, and described blue chip namely is fixed in the heat radiation substrate;

In the said structure, described radiator is aluminium base.

The beneficial effects of the utility model are: the utility model encapsulates whole LED light fixture as a large LED, the blue-ray LED of adopting process maturation is as light emitting source, by at lampshade inner-wall spraying yellow fluorescent powder, this design can improve luminous efficiency greatly, simultaneously because blue chip does not cover fluorescent material, so that blue chip can dispel the heat fully, do not need complicated power circuit and cooling mechanism yet, can simplify the design of product, reduce production costs, improve the life-span of product.

Fig. 3 is the utility model blue-ray LED encapsulating structure.

[specific embodiment]

The utility model will be further described below in conjunction with drawings and Examples.

With reference to shown in Figure 1, the utility model has disclosed a kind of novel blue light LED lighting, this light fixture have spherical lampshade 10 and with the lamp holder 20 of lampshade 10 smooth connections, in lampshade 10, lamp holder 20 upper positions are provided with driving power 30, be provided with radiator 40 around the driving power 30, the radiator 40 general good metal materials of thermal diffusivity that adopt, in the present embodiment, this radiator 40 is aluminium base, be fixed with blue-ray LED 50 on the radiator 40, in the present embodiment, be fixed with three blue-ray LEDs 50 in the lampshade 10, with reference to Fig. 2, be the cutaway view of blue-ray LED 50, this blue-ray LED 50 has plastic stent 501,501 one-tenth bowls of plastic stent cup-shaped, these plastic stent 501 bottoms are provided with cooling base 502, cooling base 502 both sides are provided with pin 503, are fixed with blue chip 504 on described cooling base 502, and this blue chip 504 is connected with pin 503 by gold thread 505, above-mentioned driving power 30 is connected on the pin 503, and is luminous to drive blue chip 504; Be filled with transparent plastic packaging glue 506 in the plastic stent 501 of this blue-ray LED 50, be coated with fluorescent coating 60 on the inwall of lampshade 10.

By above-mentioned narration, this design of the present utility model works as the LED light fixture as a large LED encapsulation, the blue-ray LED of adopting process maturation is as light emitting source, by the fluorescent coating 60 in lampshade 10 inner-wall spraying yellow, this design can improve luminous efficiency greatly, do not need to carry out secondary optical design, because lampshade 10 inside all are coated with full fluorescent coating 60, after blue ray shines on the yellow fluorescent powder, will send the light of white, the very thin thickness of fluorescent coating 60 can reduce the penetrance that improves light, improve the light efficiency of product, owing to be transparent enclosure glue 506 around the blue chip 504, do not have fluorescent material simultaneously, improved radiating efficiency, so that blue chip 504 can dispel the heat fully, do not need complicated power circuit and cooling mechanism yet, can simplify the design of product, improve the life-span of product, after product introduction is produced in enormous quantities, can effectively reduce cost.

Described above only is preferred embodiment of the present utility model, and above-mentioned specific embodiment is not to restriction of the present utility model.In technological thought category of the present utility model, various distortion and modification can appear, and the retouching that all those of ordinary skill in the art make according to above description, revise or be equal to replacement, all belong to the scope that the utility model is protected.
