Abstract
The utility model discloses a directly projecting LED illuminating bulb which comprises a closed shape outer shell, a threaded connection opening, a plurality of LED luminous bodies with same or different luminous colors; the closed shape outer shell is molded by integrating a Fresnel lens combination unit on the top and the surrounding focus outer shell; the bottom of the closed focus outer shell is provided with a seat body; the top surface of the seat body is arranged with the plurality of LED luminous bodies in concentric circle array; the bottom surface of the seat body is fixedly connected with the threaded connection opening. The illuminating light source LED, which is adopted by the utility model, has small volume, high photoelectric conversion rate, and longer service life; the purposes of raising light effect and uniform projection are obtained by using the optical structure of lens combination unit to simulate the omnidirectional projecting mode of the common illuminating bulb; the directly projecting LED illuminating bulb has features of having the bulb outer shell with focus effect and the bulb threaded opening, high efficiency, low temperature starting performance, energy saving, and longer service life, etc. ; the service life can not be affected even the directly projecting LED illuminating bulb is used under the condition of continuance or stroboscopic action. The directly projecting LED illuminating bulb is suitable to various illuminating fittings with low voltage direct current and 220V alternating current.
Description
Technical field
The utility model relates to a kind of light fixture that is used for general illumination, relates in particular to a kind of direct-injection type LED lighting bulb of LED semiconductor light emitting.
Background technology
Existing illuminating lamp generally adopts the scalding bulb, and with under the constant power, often its brightness is not enough, and power consumption is bigger, and useful life is short, does not meet energy-conservation, long-life requirement.And energy-saving fluorescent lamp exists and produces and with producing fluorescence goods and materials secondary pollution problem in the reprocessing.
The utility model content
The purpose of this utility model is to provide a kind of direct-injection type LED lighting bulb, by the electrical-optical conversion efficiency height of LED, makes that the brightness of bulb is improved, and prolongs greatly useful life, and meets the ecological, environmental protective principle under the situation of same power consumption.
A kind of direct-injection type LED lighting bulb provided by the utility model, it comprises the enclosed shape shell, hickey is color with some different colors or the LED luminous element of identical glow color, and wherein: described enclosed shape shell is one-body molded with optically focused shell on every side by the Fei Nieer combination of lenses unit at top; Bottom at described optically focused shell is provided with pedestal, is arranging some LED luminous elements by the form of concentric garden array on this pedestal end face; At this fixedly connected hickey in pedestal bottom surface.
Above-mentioned direct-injection type LED lighting bulb, wherein: Fei Nieer combination of lenses unit is the direct projection interface.
Above-mentioned direct-injection type LED lighting bulb, wherein: be provided with the circuit board of control dynamic light change in the pedestal, or transforming circuit.
Volume is little because the utility model adopts, the lighting source LED of electrical-optical conversion efficiency height and extra long life, and the optical texture by Fei Nieer combination of lenses unit, simulate the comprehensive radiation modality of common lighting bulb, reach the purpose that improves light efficiency and uniform irradiation, and configuration has the bulb shell and the standard lamp rib collar of spotlight effect, make that it has efficiently, characteristics such as cold-starting, energy-conservation and extra long life, do not influence useful life even under continuous or stroboscopic condition, use yet.The utility model is fit to the use of various lightings.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model, it is a kind of direct-injection type LED lighting bulb, it comprises enclosed shape shell 2, standard thread interface 5 is color with some different colors or the LED luminous element 3 of identical glow color, and wherein: enclosed shape shell 2 is one-body molded with optically focused shell 22 on every side by the Fei Nieer combination of lenses unit 21 at top; Be provided with pedestal 4 in the bottom of optically focused shell 22, on these pedestal 4 end faces, arranging some LED luminous elements 3 by the form of concentric garden array; At this fixedly connected hickey 5 in pedestal 4 bottom surfaces (E27 standard lamp rib collar).
Fei Nieer combination of lenses unit 21 is the direct projection interface.
Be provided with circuit board or transforming circuit or other control circuit (not shown) of the change of control dynamic light in the pedestal 4.
The utility model can reach different color display effects by the combination of the different colors coloured silk of LED luminous element 3 concentric garden arrays.
With one heart the different color of garden led array can also design by direct-injection type, and the ring of light of different color is reflected on the bulb enclosed shape shell.Require in shell block, to place dynamically change control circuit according to the user, realize that color dynamically changes irregularly.
