Embodiment Construction

[0017] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] This embodiment provides a long and narrow LED lamp with light distribution. The LED lamp is used in narrow and long tunnels or roadways in coal mine underground roadways, tunnels, cable trenches, etc. To the narrow and long direction, that is to form a long and narrow light distribution, the luminous flux of the light source is effectively utilized, the efficiency of the whole lamp is improved, and the light utilization rate can reach up to 100%.

[0019] Such as figure 2 As shown, the LED lamp includes an LED light source and a lamp body 201. The shape of the lamp body 201 is set as a trapezoid, that is, the cross section of the lamp body 201 is trapezoidal. Wherein, preferably, the lamp body 201 can be The shape is set as an isosceles trapezoid, that is, the cross section of the lamp body 201 is an isosceles trapezoid.

Abstract

The invention discloses an elongated light-distributing light-emitting diode (LED) lamp. The elongated light-distributing LED lamp comprises an LED light source and a lamp main body. The lamp main body is a trapezoidal body. The LED light source comprises a first LED light source unit and a second LED light source unit, and the first LED light source unit and the second LED light source unit are arranged on two opposite sides of the trapezoidal body respectively. Besides, each LED light source unit is respectively provided with an LED assembly, an insulating strip and a reflector. The elongated light-distributing LED lamp emits light on two faces, light on two light-emitting faces is respectively projected to an elongated direction to form elongated light distribution, luminous flux of the light source is effectively utilized, efficiency of the whole lamp is improved, and the utilization rate of the light can reach 100% to the largest extent.

Description

technical field [0001] The invention relates to a lighting device, in particular to a long and narrow LED lamp with light distribution. Background technique [0002] The lighting of coal mine tunnels, tunnels, and cable trenches is characterized by narrow and long lighting areas. The lamps currently used are basically traditional lamps with metal halide lamps as light sources. [0003] The luminous irradiation area diagram of prior art lamps and lanterns is as follows figure 1 As shown, wherein the lamp 104 is installed in the long and narrow tunnel or roadway 103, the light from the two light emitting areas 102 formed by the light emitted by the lamp 104 is not utilized, and the light from the two light emitting areas 102 is irradiated to the walls on both sides 101, that is, 50% of the light emitted by the lamp 104 is not utilized, and the utilization rate of the lamp is low. [0004] Therefore, there are defects in the prior art and need to be improved. Contents of th...
