Compared with the prior art, the utility model has the advantages of high brightness, good energy-saving effect, long service life, safety and reliability.
Description
Technical field
The utility model is a kind of high brightness diode white light source, and it relates to light emitting semiconductor device and device, is to improvement on present device and the product structure and the raising on the performance.
Background technology
Solid light source can send near monochromatic light wave, has the reliability height, long service life, the advantage that working range is wide.Light-emitting diode just belongs to a kind of like this light source.Light-emitting diode is as a kind of display device, and is not only energy-conservation but also pollution-free, but light-emitting diode has only the RGB isochrome usually, and luminous height is not high, can't be as a kind of lighting source.So, in lighting field, use solid, just must improve its luminous efficiency significantly.
Summary of the invention
The utility model is that purpose designs at the deficiency that exists in the above-mentioned present technology just a kind of high brightness of new structure diode white light source is provided, it is to utilize diode as illuminating source, and cooperation improves its luminous efficiency and brightness with suitable fluorescent material bisque, so that high-quality white light source to be provided, make it reach the needed index of illumination.Can be widely used in office, show automobile and various place.
The purpose of this utility model realizes by following measure:
This kind high brightness diode white light source, it comprises chip, lead, support reflector, terminal and the first-class assembly of resin, its structural design features is, support reflector and be provided with the led lighting chip that optical source wavelength is 400～490 nanometers, and be connected with terminal by lead, be coated with the layer of fluorescent powder layer on luminescence chip, the white light source that said apparatus constituted all is encapsulated in the transparent resin head.The chemical composition of the material that phosphor powder layer adopted that applies on the luminescence chip is: (Y
