Embodiment 3

[0057] refer to Figure 8-9 , In this embodiment, the structure of the lamp housing 1 and the structure of the lamp holder 2 are completely the same as those of the embodiment 1, and will not be repeated here. The side wall of the through opening 11 is covered with a first LED light source board 12 ″, and emits light toward the outer casing 1;

[0058] In the first section of the through opening 11, the two sides along the horizontal direction have different distances from the half-arc on the same side; the one on the first LED light source board 12" with a shorter distance from the half-arc From the side to the side of the first LED light source board 12", the number of lamp beads increases gradually;

[0059] Both sides of the opening end of the first LED light source board 12" facing the through opening 11 respectively have a second LED light source board 13" extending toward the through opening, and the part of the second LED light source board 13" facing the opening end ...

Abstract

The invention provides an LED lamp with an irregular contour capable of glowing evenly and having no dark corner. The LED lamp comprises an outer shell body and a base. Two cross sections perpendicular to each other in the vertical direction of the outer shell body are axially symmetrical in the vertical direction correspondingly; a first cross section comprises a more-than-half circular arc, and the two ends of the more-than-half circular arc section are connected through a horizontal section; a second cross section comprises a curved section, wherein one end of the curved section has an opening, the opening ends of the curved section are connected through a horizontal section, and the width of an area defined by the curved section gradually decreases from the middle to the two ends in the vertical direction; a penetrating opening is formed in the direction, deviating from the symmetric axis, of the side wall of the outer shell body in the horizontal direction, and a light source panel is arranged on the side wall of the penetrating opening and glows towards the inner portion of the outer shell body; and the number of lamp beads of one side, having a short distance from the more-than-half circular arc, of the light source panel is less than the other side of the light source panel. According to the LED lamp with the irregular contour capable of glowing evenly and having no dark corner, the LED lamp is provided, the whole outer shell body can glow evenly and have no dark corner while the LED lamp has an aesthetic contour.

Description

technical field [0001] The invention relates to an illuminating device, in particular to an LED lamp. Background technique [0002] In the lighting market, people's requirements for the aesthetic appearance of the lighting have become stronger and stronger. In a traditional lamp, generally a light bulb and a lampshade are provided. Make some designs on the shape of the lampshade to increase the beauty or artistic sense of the whole lamp. The problem brought about by this is that the lampshade and the bulb are two separate entities, and the bulbs chosen by consumers may be various, and the light output angle and brightness of each bulb are different. In this way, when manufacturers design lampshades, they often cannot make corresponding designs for the light output, and the focus is entirely on the shape. Although the produced lamps have a good-looking appearance, they tend to have uneven brightness or dark areas after lighting up. [0003] Another kind of lamp with LED l...
