Abstract
The utility model discloses a novel light-emitting diode (LED) white lamp. The lamp comprises chip brackets, wherein a blue LED chip component is arranged on the chip brackets; a fluorescence excitation layer which is made of a fluorescent material and can excite blue light to form white light is arranged above the blue LED chip component; a lens is connected above the fluorescence excitation layer; and an outer frame for fixing the lens and the chip brackets is arranged outside the lens. The lamp solves the problem that luminous efficiency and color temperature are influenced because fluorescent powder is aged and discolored and absorbs light when the temperature of a chip is high, has the advantages of low production cost and the like, and is easy to manufacture.
Description
Technical field
The utility model relates to the LED technical field of lamps, relates in particular to a kind of New LED white light light fixture.
Background technology
Along with the development and the energy-conserving and environment-protective proposal of society, the LED technology is widely used in technical field of lamps.The blue light that tradition LED white light is sent by blue chip basically be coated at blue chip surface fluorescence powder and inspire the white light that forms; Or by the white light that obtains after mixing behind the purple light chip excitated fluorescent powder or for by red; The white light green, that blue three primary colours obtain after just mixing by certain ratio.This fluorescent material that is coated in chip surface can aging and color changeable absorption phenomenon occur because of being in the higher temperatures environment for a long time.
The LED light fixture that has is coated in fluorescent material on the lens, not only comes off easily but also the manufacture craft trouble.
The utility model content
The purpose of the utility model is to the problems referred to above weak point; A kind of New LED white light light fixture is provided; Advantages such as it can avoid influencing the problem of light efficiency and colour temperature with color changeable absorption because of led chip source temperature height causes fluorescent material to wear out, and has simultaneously and makes simply, and production cost is low.
In order to achieve the above object, the utility model adopts following technical scheme:
A kind of New LED white light light fixture; Include chip set; Be provided with the blue-light LED chip assembly on this chip set; This blue-light LED chip assembly top be provided with by fluorescent material process, can be the fluorescence excitation layer of blue-light excited one-tenth white light, this fluorescence excitation layer top connects lens, this lens outside be provided with one be used for fixing lens and chip set housing.
As preferably, above-mentioned fluorescence excitation layer is fluorescence film or the fluorescence offset plate that is embedded in the lens downside.
Said chip support outer contour shape matches with housing in-profile shape.
Above-mentioned housing exterior contour is regular shape profile or irregularly shaped profile; Above-mentioned regular shape profile is a triangle, or is square, or is circular, or is oval.
The said chip support is high heat conduction PCB substrate.
Advantages such as the utility model adopts said structure, and having avoided influences the problem of light efficiency and colour temperature because of the chip temperature height causes fluorescent material to wear out with color changeable absorption, has simultaneously and makes simply, and production cost is low.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Below come the utility model is further described through the accompanying drawing and the specific embodiment.
The specific embodiment
As shown in Figure 1; A kind of New LED white light light fixture; Include chip set 5, this chip set 5 is provided with blue-light LED chip assembly 4, these blue-light LED chip assembly 4 tops be provided with by fluorescent material process, can be the fluorescence excitation layer 3 of blue-light excited one-tenth white light; These fluorescence excitation layer 3 tops connect lens 2, this lens outside be provided with one be used for fixing lens 2 and chip set 5 housing 1.Has certain spacing distance between said fluorescence excitation layer 3 and the blue-light LED chip assembly 4.Fluorescence excitation layer 3 can send white light through blue-light excited.
As preferably, above-mentioned fluorescence excitation layer 3 is for being embedded in the fluorescence film or the fluorescence offset plate of lens 2 downsides.
Said chip support 5 outer contour shapes match with housing in-profile shape.Above-mentioned housing exterior contour is regular shape profile or irregularly shaped profile; Above-mentioned regular shape profile is a triangle, or is square, or is circular, or is oval.
Said chip support 5 is high heat conduction PCB substrate.High thermal conductive substrate helps the led chip heat radiation, improves service life.
Blue light that blue-light LED chip assembly 4 sends and the white light that inspires through this blue-light excited said fluorescence excitation layer 3.Because fluorescence excitation layer 3 be fluorescence film or fluorescence offset plate, and has certain distance with chip, so not influenced by chip temperature and fluorescent material weather stain and extinction can not occur and cause the situation of light efficiency and colour temperature variation.
Advantages such as the utility model adopts said structure, and having avoided influences the problem of light efficiency and colour temperature because of the chip temperature height causes fluorescent material weather stain and extinction, has simultaneously and makes simply, and production cost is low.
The also technical scheme of unrestricted the utility model more than is described, every technology that does not break away from the utility model spirit all belongs in the claim scope of the utility model.
