Abstract

The utility model discloses a light-emitting diode (LED) illumination lamp, which comprises a lamp tube and an LED light source positioned in the lamp tube, wherein the inner wall of the lamp tube is coated with fluorescent powder. The glass lamp tube, the interior of which is coated with the fluorescent powder, converts the light emitted by the LED with single wavelength (UV or blue light LED) into white light. An LED chip is used as a luminous source in the lamp tube, LED sealant is not needed, and the glass lamp tube is filled with Ar or evacuated after assembly. The LED illumination lamp solves the problems of degradation of the sealant material and heat dissipation of the LED chip, simplifies the production process and reduces the production cost.

Description

The LED illuminating lamp

Technical field

The utility model relates to technical field of semiconductor illumination, is specifically related to a kind of LED illuminating lamp.

Background technology

Along with the continuous increase of energy resource consumption, the CO2 emission that a large amount of use caused of the coal that is used to generate electricity is pollution of ecological environment seriously.Therefore, the life style of seeking the low-carbon emission using electricity wisely becomes more and more urgent.Current, people pay attention to day by day to the development and utilization of light emitting diode (LED).LED progressively replaces new trend and the new focus that conventional lamp becomes energy-saving lamp with characteristics such as its low cost, high brightness, energy-conserving and environment-protective.

Fig. 1 is a typical LED light emitting diode construction schematic diagram.As shown in Figure 1, the LED light emitting diode comprises positive pole 10 and negative pole 20, and is electrically connected on the LED luminescence chip 30 between the both positive and negative polarity.In the periphery is transparent epoxy resin or the silica gel packaging body 40 that is used for packaging LED chips 30.The LED device concentrates on single wavelength at present, be converted into white light and must pass through fluorescent material.This mode has reduced energy conversion efficiency when being applied to photovoltaic generation.White light utilize from LED send blue light or UV (deep ultraviolet) light come activated phosphor to obtain.This fluorescent material is blended in the transparent epoxy resin or silica gel as the LED sealant material.If sealant is dropped in the LED top with liquid phase and is dried, then because gravity factor will form the packaging body 40 of convex lens shape.Led chip 30 is as spot light, and the light that sends sends the white light of dispersing after by packaging body 40.

Sealant as packaging body 40 has two kinds of effects: the first is converted to white light with single wavelength light, and it two is to sealing of 30 of led chips and moisture-proof role.But the degeneration of sealant caused usefulness after UV illumination is penetrated for a long time, and sealant also is unfavorable for the heat radiation of led chip 30.

The utility model content

Therefore, the purpose of this utility model is to provide a kind of LED illuminating lamp, can solve the degeneration and the LED heat dissipation problem of sealant material, also can simplify the making flow process.

The utility model provides a kind of LED illuminating lamp, comprises fluorescent tube and the led light source that is positioned at described fluorescent tube inside, and described tube inner wall scribbles fluorescent material.

Optionally, described led light source be one or two or plural a plurality of.

Optionally, the spectrum of the light that described two or more a plurality of led light source sent is identical or different.

Optionally, described fluorescent tube inside is filled with inert gas.

Optionally, described fluorescent tube inside is vacuum.

Optionally, described fluorescent tube is a glass lamp.

Optionally, the shape of described fluorescent tube includes but not limited to circle, ellipse or cylindrical.

Optionally, described inert gas comprises argon Ar.

Compared with prior art, the utlity model has following advantage:

LED illuminating lamp of the present utility model comprises single wavelength LED (UV or blue-ray LED) light source and the inner glass lamp that scribbles fluorescent material.Led chip need not to use the LED sealant as the light emitting source in the fluorescent tube, and after the assembling, glass lamp will be filled Ar or be extracted into vacuum.Solve the degeneration of sealant material and the heat dissipation problem of led chip, and simplified production process, reduced production cost.

Led chip can be led light source monolithic or the multi-disc that enough brightness is arranged that enough brightness is arranged.Have the glass lamp of fluorescent coating single wavelength light can be converted to white light, and the shape of glass lamp can design any desirable shape, to reach best illuminating effect.
