Description

Side light source LED bulbs and lamps

technical field

The utility model relates to an LED lamp, in particular to a lateral light source LED lamp with a positioning structure.

Background technique

Since the size and power consumption of LEDs are much smaller than those of traditional light bulbs, LEDs have been widely used in recent years, and are further introduced into larger lighting devices, such as indoor lighting or road lighting.

Compared with the spherical light source of traditional light bulbs, LED is a point light source. Therefore, when it is applied to a large-area light-emitting device, many LEDs are arranged in a plane to create a planar light source. Existing conventional LED light bulbs are no different from traditional light bulbs when mounted on vertically installed lamp holders, and most of the lamp holders are also compatible and universal.

When it is impossible to install the bulb vertically due to special restrictions (such as insufficient space inside the ceiling), it is necessary to use a horizontal lamp holder instead. Since the flat light source applied to the LED has directionality, the depth of the bulb screwed into the lamp holder will be different. When the bulb is tightened, the direction of the light source may not be vertically downward, but if the light source is adjusted to be vertically downward, the bulb may become loose and cause poor contact.

The heat dissipation fins 120 are used to discharge the heat energy of the LED light emitting element 130 into the base 110 Side light source LED light bulb 10 .

The lamp cap 200 is electrically connected to the lighting unit 100 , and the outer side of the lamp cap 200 has corresponding screw teeth to the inner side of the conductive seat 600 , so the lamp cap 200 can be screwed into the conductive seat 600 to electrically connect the lamp seat 20 to supply power to the lighting unit 100 . The insulating casing 300 is preferably a cylinder made of plastic with open ends. One end of the insulating casing 300 is connected to the lighting part 100 and extends from the lighting part 100 parallel to the lighting surface 111 , and the other end is connected to the lamp cap 200 . Preferably, two wires 210/220 are welded on the circuit board 140, passing through the line hole 113, the hollow inside the base 110, the hollow inside the insulating cover 300 and welded to the lamp holder 200, so that the circuit board 140 is electrically Sexually connect the lamp holder 200.

The positioning member 400 extends outward from the outer surface of the insulating casing 300 and obliquely deviates from the lighting portion 100 (towards the lamp head 200 ).

A pushing force tightens the screw thread of the lamp holder 200 and the conductive seat 600, and fixes the side light source LED bulb 10. Since the positioning member 400 and the conductive seat 600 have effectively fixed the side light source LED bulb 10 in the lamp holder 20, the screwing depth of the side light source LED bulb 10 only needs to reach enough to make the lamp base 200 electrically connected to the conductive seat 600. The side light source LED bulb 10 does not need to be completely locked and will not shake. After the lamp cap 200 is screwed into the conductive seat 600, the side light source LED bulb 10 can still be rotated axially to adjust the angle of the lighting surface 111, preferably making the lighting surface 111 is vertically downward (the illuminating surface 111 is horizontal), which effectively improves the shortcomings of the prior art.

The second embodiment of the present utility model provides a side light source LED light bulb 10, which is applied to be installed in a corresponding lamp holder 20, and the structure of the lamp holder 20 is the same as that of the aforementioned first embodiment.

Since the positioning parts 410/420/430/440 and the conductive seat 600 have effectively fixed the side light source LED bulb 10 in the lamp holder 20, the screwing depth of the side light source LED bulb 10 only needs to be enough to make the lamp base 200 electrically connected to the conductive The seat 600 is enough, and the side light source LED bulb 10 does not need to be completely locked and will not shake. After the lamp cap 200 is screwed into the conductive seat 600, the side light source LED bulb 10 can still rotate axially to adjust the angle of the lighting surface 111, which is relatively Preferably, the illuminating surface 111 is vertically downward (the illuminating surface 111 is horizontal).

The utility model fixes the side light source LED bulb in the lamp holder through the positioning piece. Compared with the prior art that fixes the LED light bulb in a tight manner, the utility model effectively improves the disadvantage that the prior art cannot take into account both the fixing of the LED light bulb and the adjustment of the irradiation angle.

Of course, the utility model can also have other various embodiments, and those skilled in the art can make various corresponding changes and deformations according to the utility model without departing from the spirit and essence of the utility model, but These corresponding changes and deformations should all belong to the protection scope of the appended claims of the present utility model.
