Field of the Invention The present invention relates generally to a globe lamp installed as a security lamp on a road for a pedestrian, and a deployable lighting apparatus for a globe lamp used as a security lamp so that the intensity of light irradiated on a road can be effectively increased.

Unlike streetlights, general security lamps are mainly installed on the roads, and are mainly installed for people's walking comfort. The general structure of such a security lamp is shown in FIG. As can be seen from the above, a conventional general security lamp is provided with a globe made of transparent or milky white spherical spheres at the upper end of the strut, and a lamp loading hole of about 120 mm is provided on one side of the glove, So that it is coupled to the cover having the lampholder. As described above, the general shape of the glove security lamp requires the lamp to be inserted into the lamp charging hole of about 120 mm, so that the diameter of the lighting device is basically required to be 120 mm or less.

Security lamps such as security lamps that can be used for these globe lamps are available on the market. An example of this is the website (http://itempage3.auction.co.kr/DetailView.aspx?ItemNo=A53180 9413 & scoredtype = 0 & frm2 = through & acode = ) EBay Korea model name: LEDEL75-DHE; hereinafter referred to as "cited invention 2"), which is shown in FIG.

As can be seen from this, Reference 2 has a narrow width as exemplified by 103 mm in order to be loaded into a globe lamp charging hole of a narrow width, so that the LED mounting panel has a vertical As shown in Fig. 3, the LED mounting panel is installed on one side in a horizontal plane.

In the LED lamp mounted on the conventional globe, the LEDs on the side shown in FIG. 2 are vertically arranged so that the light is dispersed while being horizontally irradiated. On the other hand, since the LEDs arranged horizontally as shown in FIG. 3 are few, There is a problem that the illuminance of the area under the security is insufficient because the illuminance can not be sufficiently raised. Therefore, in order to solve such a problem, in order to illuminate the light of the LED having strong directivity to the downward direction of the security and so on, Korean Registered Patent No. 10-1252581 (the name of the invention: a directional LED lamp for a security light and a security light device equipped with the LED, Invention 3 ') has been proposed, which is shown in FIG.

According to the third cited reference 3, since the sub-LED substrate 120 fixed on the top of the post of the security lamp is provided in an oblique direction, the illuminance of the lower part of the globe lamp is improved But the number of LEDs that can be installed on the oblique sub-LED substrate 120 is extremely limited because the globe lamp charging hole is only 120 mm, so that the amount of light is reduced and the effect of improving the illuminance under the globe lamp is insufficient It is.

In addition, since the LED according to the third embodiment of the present invention is arranged to focus the LED in a narrow space, it is necessary to install a larger heat radiation fin 30 in order to quickly release heat generated from the LED substrate 100, So that the manufacturing cost is burdened.

In order to solve such a problem, the applicant of the present invention has proposed a technique capable of adjusting the angle of light irradiation downward as disclosed in Korean Patent Registration No. 10-1667525 (entitled "Light Bulb Socket- The present invention relates to a bulb-socket type light emitting diode lighting fixture capable of adjusting a light irradiation angle by using several LED lighting modules,

A lighting device main body having a body provided between the cap and the cover and a cover for blocking an opening of the body and having a built-in power converter;

A movable body lifting / lowering guide rod installed at the center of the lid of the lighting apparatus body;

A fixing member provided on a free end of the movable member lifting and lowering guide rod so that one end of the elastic plates is detachably fixed or a plurality of LED lighting modules are coupled to each other through a first hinge and screw engaging portion of the elastic plate, Wow;

A plurality of LED lighting modules installed to be able to move up and down along the movable member ascending / descending guide rods so as to be detachable through the first hinge-and-screw connecting portion of the elastic plate, A movable body for adjusting the inclination angle or for fixing one end of the light irradiation angle adjusting pin of the elastic plates and the light irradiation angle adjusting means;

A plurality of LEDs driven by the output voltage of the power supply converter are mounted on the fixing member or the movable body through the first hinge and screw coupling portion of the elastic plate at a predetermined angle, A plurality of LED illumination modules whose light irradiation angles are changed in accordance with a change in position of the movable body that is changed by the movement of the movable body;

The module fixing portion is resiliently coupled to the back surface of the LED lighting modules and the other end is fixed to the end portion of the elastic plate fixture of the movable body or the fixture, A plurality of elastic plates for elastically supporting the movable body lifted or lowered to a predetermined position from the movable body lifting / lowering guide rope by the light irradiation angle adjusting means and allowing the angle-controlled LED lighting modules to maintain the angle;

A light irradiation unit which is installed between the outer surface of the cap of the lighting apparatus main body and the elastic plate of the movable body or the end portion of the LED lighting module fixture in combination with the light irradiation angle adjusting means and adjusts the light irradiation angle of the LED lighting modules at an arbitrary angle Angle adjusting means;

And a sphere-shaped lighting device protector detachably attached to the lighting device main body.

In this way, it is possible to manufacture various lighting apparatuses having a lamp shape by using several LED lighting modules, and it is also possible to provide a lighting apparatus which can adjust the tilt angle of LED light modules without installing expensive lenses having different light- It is possible to adjust the irradiation angle so that an economical burden including the unnecessary lens mold cost is unnecessary, and the irradiation efficiency can be improved by easily and precisely adjusting the angle with a desired angle easily.

In other words, according to the fourth reference 4, a plurality of light-irradiation angle adjusting pins with screws are raised and lowered by a worm gear formed on the inner surface of the rotating pinace pulling operation body, And a movable member is coupled between the ring-shaped fixing portion and the main body of the lighting apparatus so that the movable member can be moved up and down. By the worm gear, Wherein one end of the lowered light irradiation angle adjusting pin is fixed to the movable body, one end of the LED lighting module is fixed axially to the ring-shaped fixing part, both ends of the elastic piece are fixed between the ring- And the rear surface of the LED lighting module is brought into contact with the outer surface of the elastic plate. Therefore, according to Reference 4, the worm gear rotates to raise and lower the light irradiation angle adjusting pin when the pinning and descending operation rotating body is rotated, thereby raising and lowering the movable body, and the LED lighting module connected with the movable body and the elastic plate So that the angles are finely adjusted.

On the other hand, Reference 4 is a security lamp, and once it is deployed at an optimum installation angle, there is no need to adjust it before the replacement time. Therefore, it is necessary to use a fin-lowering operation rotating body having a worm gear, There is a problem that the manufacturing cost is increased and the productivity is lowered because the number of parts is increased.

Particularly, in the fourth reference 4, the LED lighting module is inserted into a narrow charging hole of a globe made of transparent glass or the like, and a hand is put into a narrow space to rotate the pinion- It is impossible to avoid the inconvenience of adjusting the angle by hand operation.
