Description
Technical field
The present invention relates to semiconductor solid state lighting field, belong to a kind of semiconductor LED lighting device.
Background technology
Semiconductor light-emitting-diode LED (being semiconductor solid-state optical source (SSL)) is the new developing technology beginning of this century, semiconductor solid-state optical source by industry be known as the 4th generation light source.As the light source of major technique in the lighting engineering, three developing stage have been experienced: incandescent lamp, fluorescent lamp and HID (High InyensityDischarge) lamp.Along with the continuous progress of semiconductor light-emitting-diode and the Application and Development of new material, the semiconductor light-emitting-diode semi-conductor solid-state light source is constantly improved and enter the practical stage, the high-brightness semiconductor light emitting diode will be the mankind's one of greatest inventions after Edison's invention incandescent lamp bulb.Improving the semiconductor light-emitting-diode illuminating effect is the project that present each state all researches and develops at emphasis, how improving the semiconductor light-emitting-diode illuminating effect can carry out from three aspects, the one, semi-conducting material, the 2nd, packaging technology and be used for the optics of light-emitting diode chip for backlight unit, the 3rd, the light that in the application of semiconductor light-emitting-diode semiconductor light-emitting-diode is sent is collected and is reflected to improve its illumination or brightness.For example, use many semiconductor light-emitting-diodes to make light source, spread length can not be very big between the semiconductor light-emitting-diode, the light of semiconductor light-emitting-diode primary optical axis side is easy to be blocked by the semiconductor light-emitting-diode around it, in existing products, this part light has only seldom part to be refracted into the light source shadow surface, most of refraction and having wasted between semiconductor light-emitting-diode.
Summary of the invention
The purpose of this invention is to provide a kind of semiconductor LED lighting device that can improve the illumination of light source shadow surface.
Another object of the present invention provides a kind of semiconductor LED lighting device that can make light emitting source that good performance of heat dissipation is arranged
The object of the present invention is achieved like this, it comprises the fixedly pedestal of semiconductor light-emitting-diode, the semiconductor light-emitting-diode driver, also comprise and place the fixedly end box of the pedestal of semiconductor light-emitting-diode, the reflector of adorning on the end box, be laid with reflection hole on the reflector, the reflection hole formation reflecting surface that caves inward, reflection hole is corresponding with the semiconductor light-emitting-diode on the pedestal.
In order to realize another goal of the invention of the present invention, on box of the described end, lay louvre.
Housing is equipped with in the outside, bottom of box of the described end, and the semiconductor light-emitting-diode driver places in the housing.
The present invention is owing to the characteristics at semiconductor light-emitting-diode, according to the optical reflection principle, around semiconductor light-emitting-diode, form a reflecting surface by the reflector drawing, this reflecting surface is after surface treatment, more can constitute the reflector of a high reflectance, collect to greatest extent and light that the reflective semiconductor light emitting diode sends, show that after tested the present invention improves more than 30% to the illumination of semiconductor light-emitting-diode.The present invention can delay the service life of semiconductor light-emitting-diode owing to have the good heat radiating structure with this.With the present invention is that the unit carries out a plurality of combinations, and large-scale lighting device is made in easier realization.Also owing to no bonding between reflector of the present invention and the semiconductor light-emitting-diode, be separable structure, therefore, the present invention has easy accessibility, and light source product is maintainable to be strengthened.The present invention also has and can prevent dazzle, both artistic and practical characteristics in addition.
