Embodiment Construction

[0015] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0016] In the embodiment of the present invention, a plurality of LEDs are evenly distributed on the surface of the fixing plate with a trapezoidal cross section, and the light emitted by each LED is superimposed on each other, the light output is uniform, the light angle and light intensity are large enough, and the light distribution curve is the same as that of the fluorescent lamp machine repair lamp. Consistent, meet the light distribution requirements of LED lamps.

[0017] The LED lamp provided by the embodiment of the present invention includes a lamp tube, and a fixed plate bent into a tra...

Abstract

The invention provides an LED (Light-Emitting Diode) lamp and is applicable to the field of illumination. The LED lamp comprises a lamp cylinder. A fixed board which has a trapezoid cross section after being bent is arranged in the lamp cylinder. The fixed board is provided with two inclined waist board parts and an upper bottom board part connected with the waist board parts. A plurality of heat radiating ribs are arranged on two face-to-face surfaces of the waist board parts and the upper surface of the upper bottom board part, which is connected with the face-to-face surfaces of the waist board parts. A plurality of LEDs are uniformly arranged on two back-to-back surfaces of the waist board parts and the lower surface of the upper bottom board part. According to the LED lamp, the LEDs are uniformly arranged on the surface of the fixed board with the trapezoid cross section; light emitted by the LEDs is mutually overlapped and the emergent light is uniform; a light-emitting angle and light intensity are large enough; and the light distribution curves of the LEDs are consistent with the light distribution curve of a machine maintenance lamp of a fluorescent lamp. Therefore, requirements on light distribution of the LED lamp are met, and the LED lamp has excellent anti-shock property and anti-impact property. Furthermore, the LED lamp is used as an illuminating device and can be used as the machine maintenance lamp or a tent lamp.

Description

technical field [0001] The invention belongs to the lighting field, in particular to an LED lamp. Background technique [0002] Commercially available hand and machine lamps generally use fluorescent lamps as light sources, such as figure 1 shown. Because the fluorescent lamp is fragile, the anti-vibration performance and shock resistance performance of this lamp are poor. figure 2 The light distribution curve of the fluorescent machine service lamp is shown. [0003] At present, some machine repair lights use LEDs as light sources, but the light distribution of the LED lamps does not meet the requirements, such as problems such as too small luminous angle, insufficient light intensity, and uneven luminescence. Contents of the invention [0004] The object of the present invention is to provide an LED lamp, aiming at solving the problem that the light distribution of the existing LED lamp does not meet the requirements. [0005] The present invention is achieved in th...
