Abstract
The utility model relates to a white light diode. A gallium nitride blue light chip is coated with a layer of fluorescent powder mixed with epoxy resin, the wavelength of the gallium nitride blue light chip of the utility model is 430-475 nm, the fluorescent powder is yttrium aluminate cerium or zinc sulphide cadmium silver, and a fluorescent layer which sends out yellow light is formed. The blue light sent by the chip of the utility model and the yellow light sent by the fluorescent layer form a white field, causing the diode to send out high brightness white light. The service life of the diode can reach 100 million hours, which is 100 times longer than a fluorescent lamp, and the power consumption of the utility model is only one tenth of a light source with the same light brightness. The light source made by the utility model has energy saving, handiness, firmness and long service life. The utility model has the wide application range.
Description
The utility model belongs to light emitting semiconductor device.
At present, the research and development of various light sources all develop to energy-conservation, pollution-free direction, though the electricity-saving lamp comparison energy savings of some fluorescence classes is being made and fluorescent material contaminated environment when discarded, the life-span of lamp is generally shorter.Light-emitting diode is as a kind of display device not only power saving, but also free from environmental pollution, and the life-span is longer, but generally all send ruddiness, colourama such as green, orchid, the brightness of sending is also not enough, must be improved as light source.
The novel purpose of this reality is to provide a kind of diode that emits white light that light source is used that can be used as.
The purpose of this utility model realizes by technical scheme shown in the drawings, it comprises chip 1, reflection shield 2, spun gold 5, support (pin) and colourless epoxy resin mushroom 3, it is the gallium nitride blue streak chip of 430-475 nanometer (nm) that the utility model adopts wavelength, on this chip, apply fluorescent material-yttrium aluminate cerium or the zinc-cadmium sulfide silver that one deck mixes with epoxy resin, form the fluorescence coating 4 of a jaundice light.The wavelength of yttrium aluminate cerium or zinc-cadmium sulfide silver is 530 nanometers, and the thickness of fluorescence coating is at 0.1-0.9 micron (μ), and the colour temperature (color) that the thickness difference of fluorescence coating can make the light that diode sends and color rendering index (light color pure) are different.
Structure of the present utility model has produced the effect of a light conversion, and the blue streak excitated fluorescent powder that chip goes out sends gold-tinted, and at this moment, wavelength is that the blue streak of 430-475 nanometer and the gold-tinted of 530 nanometers can form one white, and diode sends white light.The life-span of diode can reach 100,000 hours, be incandescent and 100 times of fluorescent lamp, and power consumption only be identical luminosity light source 1/10th, energy-saving effect is fairly obvious, the light source made from the utility model has advantage energy-conservation, light, firm, long service life, simultaneously free from environmental pollution, its social benefit is fairly obvious.The utility model range of application is extremely wide, the light source of making can replace tungsten halogen lamp, incandescent lamp etc. as outside the general illuminating lamp, also can be used for manufacturing auto lamp, traffic lights etc., the light fixture made from the utility model also is particularly suitable for various burn-proof and explosion preventions place and the various occasion that does not have alternating current.
Accompanying drawing is the utility model structural representation.
Embodiment
Chip adopts gallium nitride, and fluorescent material adopts the yttrium aluminate cerium, fluorescent material be coated on the chip after epoxy resin mixes, 0.5 micron of coating layer thickness (μ), with colourless epoxy resin as the mushroom head.Present embodiment colour temperature 6000K, color rendering index are 85.
Claims (1)
