Description of the Invention: [Technical Field] [0001] The present invention relates to a lighting device, and more particularly to a light-emitting diode lamp capable of reducing glare. [0002] [Previous Technology·] Compared with traditional light sources, LEDs have the advantages of small size, long life, low driving voltage, fast start-up, environmental protection, anti-vibration and compression resistance, and are now widely used in daily life. Indoor lighting. However, due to the small illuminating point and beam angle of the illuminating diode, the light intensity of the illuminating diode is usually concentrated, which is easy to cause glare to the observer, causing adverse reactions such as visual fatigue and headache of the observer. SUMMARY OF THE INVENTION In view of the above, the present invention provides a light-emitting diode lamp with high uniformity of light emission and reduced glare. [0004] A light-emitting diode lamp comprising a base and a lamp cover and a light source substrate fixed on the base, wherein the light-emitting substrate is mounted with the light-emitting diode', and the light-emitting diode is further disposed between the light cover and the light source substrate The light distribution plate is respectively opposite to the lamp cover and the light source substrate, and the light distribution plate is formed with a protrusion. Both ends of the base include an inclined reflection portion, and the reflection portion is formed with a reflection layer, and the protrusion is used for Light from the light-emitting diode incident on the light distribution plate at a predetermined incident angle is totally reflected to the reflective layer, and the reflective layer reflects the light to the lamp cover. [0005] The above-described light-emitting diode lamp changes the emission direction of light through a light distribution plate to make the illumination more uniform, thereby reducing glare. 099135036 [Embodiment] Form No. A0101 Page 3 / 11 Page 0992061162-0 201215815 [0006] [0007] [0009] Please refer to both FIG. 2 and FIG. 2, the light-emitting diode lamp (10) is roughly elongated. The tubular structure includes a base 1 , a lamp cover 2 , a power connector 3 , a light source substrate 40 , and a light distribution plate 50 . The lamp cover 2 is fixed to the base plate 〇 with the light source substrate 4, and the light distribution plate 50 is placed between the cover 20 and the light source substrate 40. The power connector 30 is disposed at both ends of the light-emitting diode lamp 1 , and the power connector 30 is electrically connected to a power source (not shown). The light source substrate 4 is electrically connected to the power connector 30, and a light-emitting diode 42 is mounted thereon. The light distribution plate 50 is for changing the direction of light emitted from the light-emitting diode 42. The susceptor 10 is made of an aluminum alloy substrate with good heat dissipation, and can dissipate the heat generated during operation of the illuminating diode lamp 100. The bottom of the susceptor 1 is provided with a plurality of heat dissipating fins 12 spaced apart from each other at a distance, and the heat dissipating fins 12 is used to increase the surface area of the susceptor 10 to speed up air circulation and heat dissipation. The susceptor 10 is formed with a accommodating cavity 14 in which the light source substrate 40 is housed. Both ends of the base 10 include a slanted reflecting portion 16, and the reflecting portion 16 surface forms a reflecting layer 15' for totally or diffusely reflecting light projected onto the reflecting portion 16. The edge of the reflecting portion 16 is formed with a card slot 18, and the edge of the lamp cover 20 is: ... : ' - ':::::;::. 乂. The latching portion 22 is extended toward the opposite side, the buckle The portion 22 is inserted into the card slot 18 to fix the lamp cover 20 to the base 1b. The light source substrate 40 and the pedestal 1 贴 are bonded by a high thermal conductive thermal conductive tape, and the thermal conductive tape can better conduct the heat generated by the light source substrate 40 to the susceptor 10 and then heat the air through the heat dissipation fins 12 . exchange. In the present embodiment, the light distribution plate 50 and the globe 20 are integrally formed, and both sides of the light distribution plate 50 are opposed to the light source substrate 40 and the globe 20, respectively. The light distribution plate 50 is formed opposite the light emitting diode 42 with an isosceles triangular protrusion 52 having a cross section, and the protrusion 52 is used to transmit the forward and near forward direction from the light emitting diode 42. 099135036 Form No. A0101 Page 4 / Total 11 pages 0992061162-0 201215815 The light is totally reflected to the reflective layer 15. The cross section of the projection 52 may also be other shapes such as a curved surface. [0010] As with reference to FIG. 3 and FIG. 4 at the same time, the light-emitting diode 42 projects the light emitted from the forward and near-emitting light to project the mysterious protrusion 52 and is totally reflected by the protrusion 52 to the upper layer of the reflective layer 15, which is The reflective layer 15 is totally or diffusely projected onto the light distribution plate 50. After two reflections, the incident angle of the light incident on the light distribution plate 50 is greatly increased. The light is refracted by the light distribution plate 50 and projected onto the area of the lamp cover 20. Accordingly, the 'increased light exit angle of the light-emitting diode 42' makes the distribution density of the light more uniform and the light effect is softer, thereby reducing glare.
