Description
Technical field
The utility model relates to a kind of LED light-emitting device.
Background technology
The LED(light emitting diode) device is as a kind of novel solid light source, have not only that power consumption is low, volume is little, fast response time, long working life, be easy to the advantages such as light modulation toning, energy-conserving and environment-protective, and also greatly surmounting the conventional light source such as incandescent lamp, fluorescent lamp aspect production, manufacturing, application, therefore since the sixties are born, obtained significant progress.Be widely used at present the multiple lighting fields such as the illumination of LED lamp, Landscape Lighting, large screen display, traffic lights, room lighting, the utility model relates to the application of LED on Tunnel Lamp uses.
The LED Tunnel Lamp light source of main flow is mainly excite Yellow luminous powder and get with blue light, and traditional handicraft is to be coated on blue chip after Yellow luminous powder and silica gel mixing, through heating, silica gel to be solidified, namely to can be made into LED Tunnel Lamp light source.But, the formed LED Tunnel Lamp of traditional handicraft light source, because luminescent powder directly contacts with chip, and chip temperature around luminescent powder when work can raise rapidly, and luminescent powder because the heat that chip light emitting produces is aging, causes its luminous efficiency to descend as a result.In addition, the chromaticity coordinates of luminescent powder also can be offset because of the rising of operating ambient temperature, finally affects luminous efficiency, glow color and the service life of LED Tunnel Lamp.
In order to solve easily aging problem of luminescent powder in traditional LED Tunnel Lamp, people have attempted in LED Tunnel Lamp manufacturing process, luminescent powder and chip being divided and have been arranged.LED Tunnel Lamp in existing technique, although luminescent powder and chip are separated, slowed down the aging speed of luminescent powder, still, due to the limitation of LED chip rising angle, the rising angle of the LED Tunnel Lamp that makes thus is less, and light distribution is inhomogeneous, namely in the situation that from the chip sustained height, centered by the chip dead ahead, distance center light intensity nearby is the strongest, along with the increase light intensity of distance dies down gradually.
In order to address the above problem, publication number is that the application for a patent for invention employing of CN101943329A arranges a reflecting piece on phosphor powder layer, allow the light that fluorescent material sends scatter out after the surrounding reflection, reduce whereby dazzle, publication number is that the application for a patent for invention of CN1996288A is processed by rational, make the exiting surface surface roughening of lens and produce microcosmic soft focus effect, thereby reduce halation.But aging problem of the overheated rear fluorescent material of unresolved rising angle and device still both, publication number is that the application for a patent for invention employing of US2007/0120135A1 is distributed in inner lens surfaces/outer surface with fluorescent material, and then the technique of separating with chip, according to analog computation, after using described method to encapsulate, the packaging efficiency of product can be near 100%.But this technique still faces the rising angle problem of white light, and needs fluorescent material is distributed in the substrate place of chip, fragile chip in manufacture process.
Summary of the invention
In order to solve the problems of the technologies described above, the purpose of this utility model is to provide a kind of LED Tunnel Lamp, and it comprises substrate, is positioned at the chip on described substrate; The support of lens that is positioned on described substrate and is spaced apart with described chip; Be arranged on the first luminescent film of described support of lens outer surface; This support of lens and described the first luminescent film close contact, and comprise luminescent powder in described the first luminescent film.
Support of lens in the utility model is used glass material, and the first luminescent film is used the silicon rubber material, mixes luminescent powder in the first luminescent film, and the first luminescent film is sleeved on support of lens, and support of lens covers chip, forms luminescent device.Form the LED Tunnel Lamp by a plurality of luminescent device combinations as light source.Adopt in the utility model and scatter uniform recyclable luminescent powder, avoid occurring the problem of aperture and hot spot, the use support of lens is heat insulation, reduced the temperature at luminescent powder place, improved the brightness of luminescent powder, and then reduced the aging decay of luminescent powder, thus the service life of whole light fixture extended, and assembling, convenient disassembly.
