Description

The LED lighting device

Technical field

The utility model relates to a kind of LED (light emitting diode) lighting device, relates in particular to a kind of LED lighting device that increases the light source projects angle, can increase brightness effects simultaneously.

Background technology

Early stage illumination at home and automobile all are to adopt by osram lamp with back car light and indicator, in recent years and then extend to the LED luminescence component of long service life, power saving, usability timeliness length.When being distinguished with regard to two kinds of light-emitting modes, its light source irradiation of tradition osram lamp is fan-shaped mode, though and the LED bulb has bright projection source, but very big with traditional osram lamp difference, it presents with linear fashion projection source effect, and the LED bulb of using as present automobile industry is under the not enough situation of irradiating angle and brightness, its structural design all is that the LED bulb of whole of implantation just is effective, and is used for the brake and the indicator at rear more; Illumination is subject to the projection of LED luminescence component linear fashion equally at home in addition, must add reflection shield in LED luminescence component periphery as automobile, illumination need consider that not only the problem of reflection shield and profile are restricted at home thus, also so not generally the LED luminescence component is used for illumination at home.

The light source characteristic of LED light emitting diode is: the angle when luminous heals small light source will be brighter, otherwise angle more then brightness is darker, can't reach the light source of approximate bulb fan shape, also because of the shortcoming of LED angle illumination deficiency, have only from structure and improve, just can enlarge range of exposures and brightness.United States Patent (USP) the 434th, No. 510 a kind of bulb is disclosed, it is after arranging several LED on the circuit board, also ring is established several rank and is that level is curved establishes a plurality of LED downwards around the lower edge, like this, a plurality of LED of establishing of ring make ring establish the LED refract light source via the light source reflection of lampshade reflector according to lampshade reflector indent radian around.Though this patent strengthens the LED lighting source scope of being arranged on the primary circuit plate, yet because of ring is established led light source with after the level projection, the circle light source can weaken greatly outside after the lampshade reflector is reflected, form very not bright outer ring halation result, still can't reach as its fan-shaped light source irradiation mode of traditional osram lamp, make the light illumination effect not enough, obviously this structure has further improved necessity.

Summary of the invention

Have very bright on the light source projects effect and projection scope problem widely inadequately in order to solve, the utility model provides a kind of can effectively increase integrated light source crevice projection angle scope, also reaches the more LED lighting device of bright illumination effect simultaneously.

For achieving the above object, LED lighting device of the present utility model, this infundibulate reflection shield top edge mouth is provided with a circuit board, the a plurality of LED of seam on the circuit board, its below connects lead and is arranged in outside the reflection shield perforation, also pass outside another circuit board central perforation that is positioned at root edge simultaneously, and around this another circuit board a plurality of LED of seam, and be located on the outer LED of infundibulate reflection shield and be the inclination angle; At reflection shield bottom chimeric one transparent drain pan, the housing upper limb then is bonded with a lampshade, is closed in drain pan lower edge lamp socket with cover by the connection lead below each circuit board and does being communicated with on the circuit.

LED lighting device of the present utility model has following advantage:

1. power saving, life-span are long.

2. can use for a long time, temperature is in constant temperature.

3. brightness of illumination is fan shape, and range of exposures approaches conventional bulb.

4. irradiated area is wide, and don't the thorn eyes.

5. improve that original LED bulb angle is little, the shortcoming of the broad deficiency of brightness.

The specific embodiment

Be example with a most preferred embodiment below, and conjunction with figs. describe structure of the present utility model, function in detail, so that increase to understanding of the present utility model.

As shown in Figure 1, the utility model is a kind of LED lighting device, its primary structure a: circuit board 20 is set above infundibulate reflection shield 10, after arranging a plurality of LED30 by seam on this circuit board, the lead 21 that this circuit board below is connected is arranged in outside the reflection shield central perforation 11, do being connected on the circuit with the perforated outer circuit of another circuit board 20 that is embedded on the lower edge lamp socket 60, and around this circuit board a plurality of LED30 of seam, the LED that ring is established through infundibulate reflection shield phase fit presents inclination angle laterally, and on the upper limb circuit board, cover a transparent material lampshade 40, it is one that the infundibulate reflection shield then binds with another drain pan 50 outward mutually, merges the connection of doing on the circuit by bottom one metal lamp holder by the below cover at last.

Below with reference to shown in Figure 2, be light source projects angular region schematic diagram of the present utility model.After the circuit board above the lamp socket 60 20 is peripherally installed with a plurality of LED30, in, outer phase fit via infundibulate reflection shield 10 and transparent drain pan 50, also form inclination angle laterally when allowing LED reach fixing, the LED30 of institute's seam is with projection source as the nearly straight line on the circuit board 20 of infundibulate reflection shield edge mouth, peripheral through ring is established after LED such as grade then be with projected outward light source as fan-shaped, can not only effectively increase the projected area of light source, also allow light source near the mode of delivery of traditional osram lamp, also can increase simultaneously the projection lightness of light source integral body, reach the performance LED high life, the LED lighting device of long Use Limitation feature.

Shown in Fig. 3,4,5,6,7, implement schematic diagram with the utility model optimum operation and be illustrated.By the conversion of the lampshade 40 of drain pan 50 tops being made different shaping after mutual glutinous establishing, can increase the polytropy on its outward appearance visual effect, lamp socket 60 patterns of drain pan below institute fit also can be along with environment for use and demand change simultaneously, and as at home illumination, automobile with or be multi-function way such as flashlight, increase the practical characteristic of LED lighting device integral body by this.

In sum, the LED lighting device that it disclosed, this structure is a plurality of arrangement of seam LED on circuit board, the below is through cover unification infundibulate reflection shield, by a plurality of arrangement of the peripheral seam of bottom lamp socket interior circuit board LED, be located on outer rim through being sleeved on the infundibulate reflection shield, by upper and lower Transparent lamp shade and drain pan tabling one, can increase the light source projects angle toward LED such as upper limb inclinations to be located on reflection shield, simultaneously can effectively increase the not brightness effects of bright light haloing of outer shroud tradition, and be provided with being used in behind illumination at home and the automobile on the car light.

The above only is one of the utility model embodiment, and it can not limit protection domain of the present utility model, and is all according to institute's equivalent variations of doing or modification in the utility model scope, must belong to the utility model covering scope.
