Abstract
A white-light LED lamp comprises a lamp cap, an LED driving circuit, an LED light source, a heat dissipating shell and a lampshade. The LED driving circuit and the LED light source are arranged in the heat dissipating shell, one end of the heat dissipating shell is fixedly connected with the lamp cap, the other end of the heat dissipating shell is fixedly connected with the lampshade, the LED light source is a blue light emitting chip, and a fluorescent layer is arranged on the wall of the lampshade. The white-light LED lamp has the advantages of being simple in structure, convenient to install, use and replace, low in cost and easy to popularize, more importantly, the service life of the white-light LED lamp can be prolonged, and the problem of color drift can be avoided.
Description
Technical field
The utility model relates to a kind of LED lamp, especially a kind of white LED lamp that is suitable for general illumination.
Background technology
LED lamp is that alternative traditional photograph is the Novel energy-saving lamp of light fixture.Conventional incandescent power consumption is high, the life-span is short; under the overall situation of global resources anxiety; gradually, by national governments, forbidden producing; substitute products are electronic energy-saving lamps thereupon; although electronic energy-saving lamp has improved energy-saving effect; but owing to having used the heavy metal element of many contaminated environment, run counter to again the main trend of environmental protection.Along with the high speed development of LED technology, LED illumination becomes the only choosing of novel green illumination gradually.LED is far superior to traditional lighting product in the aspect of principle of luminosity, energy-saving and environmental protection.Due to incandescent lamp and electronic energy-saving lamp in people's routine use still in occupation of very high ratio, in order to cut the waste, LED illumination manufacturer must develop the LED illuminating product that meets existing interface and people's use habit, make people in the situation that not needing to change former conventional lamp pedestal and circuit, just can use LED illuminating product of new generation, so LED white light just arises at the historic moment.But, traditional LED white light, as the LED lamp of LED bulb lamp or candle, mostly adopt white light LEDs luminescence chip, and white light LEDs luminescence chip is surface encapsulation layer of fluorescent powder at LED blue chip, form, due to LED luminescence chip in use, can produce a large amount of heats, so directly cause the fluorescent material lost of life, affect the life-span of LED white light.
Utility model content
In order to overcome the problems referred to above, the utility model provides a kind of LED white light service life of can extending to society, and the LED white light that can avoid the problem of color drift to produce.
The technical solution of the utility model is: a kind of white LED lamp is provided, comprise lamp holder, LED drive circuit, LED light source, heat-dissipating casing and lampshade, described LED drive circuit and described LED light source are placed in described heat-dissipating casing, described heat-dissipating casing one end is fixedly connected with described lamp holder, the other end is fixedly connected with described lampshade, described LED light source is blue-light-emitting chip, on described lampshade wall, is provided with fluorescence coating.
As to improvement of the present utility model, described fluorescence coating is arranged on the inwall of lampshade or on outer wall.
As to improvement of the present utility model, described heat-dissipating casing forms by ceramic material.
As to improvement of the present utility model, described lamp holder is screwed socket or bayonet socket.
As to improvement of the present utility model, described lampshade is spherical.
The utlity model has simple in structurely, easy to install, it is convenient to change, and cost is lower, is easy to universal advantage, more importantly can extend the service life of LED white light, can avoid the problem of color drift to produce.
Accompanying drawing explanation
Fig. 1 is the generalized section of a kind of embodiment of the utility model.
The specific embodiment
Refer to Fig. 1, what Fig. 1 disclosed is a kind of white LED lamp, comprise lamp holder 1, LED drive circuit 2, LED light source 3, heat-dissipating casing 4 and lampshade 5, described LED drive circuit 2 and described LED light source 3 are placed in described heat-dissipating casing 4, described heat-dissipating casing 4 one end are fixedly connected with described lamp holder 5, the other end is fixedly connected with described lampshade 5, and described LED light source 2 is blue-light-emitting chips, on described lampshade 5 walls, is provided with fluorescence coating 6.This design strengthens the distance between blue-light-emitting chip and fluorescence coating 6, and the heat that uses chip to send can not directly act on fluorescence coating 6, therefore, can extend widely the service life of fluorescence coating 6, and can avoid the problem of color drift to produce.
In the utility model, described fluorescence coating 6 can be arranged on the inwall of lampshade or on outer wall.Described heat-dissipating casing forms by ceramic material, has better radiating effect.Described lamp holder 1 can be screwed socket or bayonet socket.Described lampshade 5 can be spherical, can be also flame-shaped, as makes the shape of candle lamp.
In the utility model, described LED drive circuit 2 is prior aries, here repeats no more.
Claims (5)
1. a white LED lamp, comprise lamp holder, LED drive circuit, LED light source, heat-dissipating casing and lampshade, described LED drive circuit and described LED light source are placed in described heat-dissipating casing, described heat-dissipating casing one end is fixedly connected with described lamp holder, the other end is fixedly connected with described lampshade, it is characterized in that: described LED light source is blue-light-emitting chip, on described lampshade wall, be provided with fluorescence coating.
2. white LED lamp according to claim 1, is characterized in that: described fluorescence coating is arranged on the inwall of lampshade or on outer wall.
