Abstract
The utility model discloses a high color rendering white light lighting light emitting diode (LED) which comprises a plastic support, a positive electrode and negative electrode pin rack and a transparent cover. The transparent cover is transparent glue with fluorescent powder arranged on the surface. The plastic support is provided with a circuit board and an LED bead arranged on the circuit board. The LED bead is coated with the transparent glue. A color rendering index is larger than 90, light intensity is high, power consumption is low and lighting efficiency reaches about 200lm/W to the maximum degree. Compared with a filament lamp and a fluorescent lamp, the high color rendering white light lighting LED is obvious in advantage in the aspect of saving energy, high in reliability and long in service life.
Description
Technical field
The utility model relates to lighting field, is specifically related to a kind of LED of high whitening optical illumination.
Background technology
At present, the lighting engineering of employing light emitting diode (LED) lamp has been widely used in industrial production, the life illumination, tradition LED utilizes light emitting diode as excitation source, excite the fluorophor that can produce gold-tinted respectively, the effect that yellow fluorophor produces is undesirable, the effect that does not have white light, its colour rendering index is low.
The utility model content
Problem to be solved in the utility model provides a kind of LED of high whitening optical illumination.
For addressing the above problem, the utility model is realized by following scheme: a kind of LED of high whitening optical illumination, it comprises plastic rubber bracket, both positive and negative polarity pin frame, translucent cover, this translucent cover has the transparent glue of fluorescent material for the surface, described plastic rubber bracket is provided with the LED lamp pearl on wiring board and the wiring board, and described transparent glue wraps up this LED lamp pearl.
The beneficial effects of the utility model:
1, colour rendering index becomes a developing direction of following LED illumination greater than more than 90;
2, the light intensity height is low in energy consumption, and luminous efficiency reaches as high as about 200lm/W, makes white light LEDs compare with fluorescent lamp with incandescent lamp, and the advantage aspect energy-conservation is obvious further;
3, reliable high, the life-span is long.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, a kind of LED of high whitening optical illumination, it comprises plastic rubber bracket 3, both positive and negative polarity pin frame 2, translucent cover, this translucent cover has the transparent glue 1 of fluorescent material for the surface, described plastic rubber bracket 3 is provided with the LED lamp pearl on wiring board and the wiring board, described transparent glue 1 this LED lamp pearl of parcel.
The utility model is used light emitting diode and is cooperated the powder of multiple tool fluorescent characteristic to make white light emitting diode, utilization can be sent the light emitting diode of blue light as excitation source, excite the fluorophor that can produce ruddiness and gold-tinted respectively, simultaneously, again at the characteristic of this two wave bands fluorescence, utilize the fluorescent characteristic of other more than one fluorescent material to give reinforcement or modification, and these three fluorescence that contain above wave band can produce white light after mixing, only compare with known with yellow fluorophor, the white light of fluorescence reinforcement of the present invention and modification technique gained has the high advantage of color rendering, and make simply, be fit to a large amount of production.
