Description of the invention: [Technical field to which the invention pertains] The present invention relates to a lighting device, and more particularly to a luminous body lamp. [Prior Art] As a new generation of third-generation light source, the diode is generally favored by the market because of its long working life, energy saving and ring material. The module composed of the light-emitting diode can generate high power. High-brightness light sources are increasingly replacing conventional light sources such as incandescent lamps in luminaires, such as interior lighting. However, the light-emitting diode module provides a point light source, which is easy to cause glare, and the naked eye can directly feel the discomfort and directly damage the eyes. ~ [Invention] There is a need to provide a kind of light-emitting diode lamp with soft light effect. A light-emitting diode lamp includes a lamp cover and at least one light-emitting diode module. The lamp cover includes a concave casing. The top of the casing is provided with a mouth and a fixing plate. In the housing, the at least one LED module is attached to one side of the fixing plate and spaced apart from the inner wall of the housing. The at least one portion of the light emitted by the LED module is illuminated first. It is to the inner wall of the casing, and then is reflected by the inner wall to the outside of the opening. A light-emitting diode lamp comprises a lampshade and two rows of light-emitting diodes 6201002986, wherein a recess is formed in the lampshade, the top of the lampshade forms an opening communicating with the outside, and the two rows of light-emitting diodes are along the length of the lampshade The direction is arranged in the center of the groove of the lampshade, and the two rows of light-emitting diodes are disposed opposite to each other, and the light emitted by each row of the light-emitting diodes is firstly irradiated onto the inner wall of the lampshade facing the row of the light-emitting diodes. And the reflection of the inner wall is irradiated toward the opening of the lampshade. By reflecting the inner surface of the lampshade, the light of the light-emitting diode module is simultaneously radiated from the inner side of the lampshade to the outside of the opening, thereby forming a softer surface light source to avoid glare. [Embodiment] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. Please refer to FIG. 1 and FIG. 2 , which illustrate a light-emitting diode lamp 100 according to a preferred embodiment of the present invention. The lamp 100 includes a lamp cover 10 , a fixing plate 20 , and two light-emitting diode modules 30 . The lampshade 10 is a recessed housing, and the two LED modules 30 are mounted in the lampshade 10 by the fixing plate 20. The lampshade 10 includes a housing 11 and two end plates 13. The housing 11 extends in the longitudinal direction and has a U-shaped cross section, i.e., the housing 11 forms a recess from the top to the bottom. The housing 11 has a U-shaped inner wall 110. The bottom of the housing 11 is provided with two through holes 16. In other implementations, the housing 11 can also have other concave shapes, such as hemispherical, semi-ellipsoidal, longitudinal arches having a "V" shape or a trapezoidal cross section, and the like. The two end plates 13 are semi-circular flat plates, and the two end plates 13 are integrally connected to the longitudinal ends of the casing 11 respectively, and the casing 11 and the end plates 13 are formed to define a groove 15. The end plate 13 has an inner wall 130 opposite the inner wall 110 of the housing 11. The top of the lampshade 1 opposite the through hole 16 is provided with a weir opening 156 which allows the groove 15 to communicate with the outside. The width of the groove 15 is gradually widened in a direction from the bottom to the top of the lampshade. The surfaces of the inner walls 110, 130 are coated with a highly reflective material such as a key or mineral. The fixing plate 2 can be made of a material having a good thermal conductivity, such as a plate or a copper plate. The fixing plate 20 is a rectangular flat plate. The fixing plate 2 extends from one end of the casing U to the other end in a direction parallel to the longitudinal direction of the casing 11. The mounting plate 20 includes two symmetrical vertical sides 23 for mounting the LED module 30. The bottom of the fixing plate 2 is also provided with two fixing holes 26 (see Fig. 4) which correspond to the through holes 16 of the casing 11. The screw 60 can be passed through the through hole 16 and locked in the fixing hole 26, so that the fixing plate 20 is vertically mounted in the lamp cover 10. In other embodiments, the fixing plate 20 can also be integrally connected with the housing u. Referring to FIG. 3 at the same time, each of the LED modules 3 includes a substrate 31 and a plurality of LEDs 33. The substrate 31 extends in a direction parallel to the fixing plate 2A and is slightly shorter than the fixing plate 20. The light-emitting diodes 33 are mounted on the substrate 31 at even intervals in the longitudinal direction. The substrate 31 is provided with a layer of printed circuit electrically connected to the light-emitting diode 33. The substrate 31 is respectively soldered on the side surface 23 of the solid plate 20 by welding, and the light-emitting diodes 33 on both sides are staggered along the length direction of the fixed plate 20, so that it can be divided into 8 201002986 The heat generated by the body 33 during operation 'achieves a better heat dissipation effect. The light-emitting diode 33 such as Wen is opposed to the inner wall n〇 of the casing u. The light-emitting diodes 33 are divided into two rows, which are respectively located on the left and right sides of the fixed plate 2'. Each row of the light-emitting diodes 33 (four) are mounted on the corresponding substrate 31, and the two rows of the light-emitting diodes 33 are opposite each other. Settings. Referring to Fig. 4 at the same time, the fixing plate 20 is located at the center of the groove 15 and is disposed along the length of the lamp cover 10, thereby dividing the groove 15 into two portions symmetrical left and right. Each of the light-emitting diodes 33 has a light-emitting surface 33, which is opposite to the inner wall ι1 of the casing 11. Light emitted from the light emitting surface 33A intersects the inner surface of the globe 10. For example, a portion of the light 71 emitted by the light-emitting surface 330 is first irradiated onto the inner wall; and then irradiated toward the opening 156 by reflection of the inner wall 110. A part of the light (not shown) is irradiated toward the opening I% by the reflection of the inner wall 130 of the end plate 13. In particular, in the present embodiment, the light emitted from the edge of the light-emitting surface 330 at the maximum light exit angle just intersects the edge of the casing or end plate 13, such as light 73. In any event, the light of the light-emitting body 33 is first reflected by the inner surface of the lamp cover 10 and then radiated from the opening 156. Therefore, the human eye cannot directly see the light emitted by the light-emitting diodes 33 from any angle outside the opening 156 of the lamp 100. By reflecting the inner surface of the lampshade 1 ,, the light of the light-emitting diode 33 is simultaneously irradiated to the outside of the opening 156 from a plurality of directions inside the lampshade, thereby forming a softer surface light source, thereby avoiding glare. . In other embodiments, most of the light of the LED 33 needs to be reflected by the inner surface of the lamp cover 10 of the 201002986, and part of the light may be directly directed to the opening 156 without being reflected by the inner surface of the lamp cover 10, so that To a large extent, glare can also be alleviated. In summary, the present invention complies with the requirements of the invention patent, and proposes a patent application according to law. However, the above description is only a preferred embodiment of the present invention, and the equivalent modifications of the present invention in the spirit of the present invention are intended to be included in the following claims.
