Problems solved by technology

Moreover, for large-area lighting environment, the existing technology is to use floodlights. Since it is full-circle lighting, most of the light is irradiated to the upper space, but not projected on the work surface, and the light projected on the wall of the upper space is not blocked. Utilization, that is, about 40% of energy is wasted, and the utilization rate of lamps is low

Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] This embodiment provides an LED lamp with surrounding light distribution. The LED lamp is suitable for fixed lighting in environments with potentially explosive gases, such as centralized control rooms in coal mines, oil fields, factory areas, etc., with four-sided light and four-sided light. All are projected onto the working surface, which forms a ring-illuminated light distribution. The luminous flux of the LED light source is effectively utilized, the efficiency of the whole lamp is high, and the light utilization rate can reach up to 100%. Moreover, the LED lamp is equipped with an explosion-proof shell, which has a good explosion-proof effect. .

[0023] Among them, such as figure 1 As shown, the LED lamp includes an LED light source unit 104 and a lamp body 101. The shape of the lamp body 101 is set as a trapezoid, that is, the...

Abstract

The invention discloses an all-round light-distribution LED lamp which comprises an LED light source unit and a lamp body. The lamp body is in the shape of a trapezoid, the LED light source unit is provided with four sets of LED light sources which are respectively arranged on four side faces of the trapezoid, and each set of LED light source is provided with an LED component, an insulating piece and a reflector. The all-round light-distribution LED lamp can emit light all round, light emitted all round is all projected on a working face, and all-round light distribution is realized; and light flux of the LED light sources is effectively utilized, the all-round light-distribution LED lamp is high in efficiency, and light utilization rate can reach 100% at most.

Description

technical field [0001] The invention relates to an illuminating device, in particular to an LED lamp with surrounding lighting and light distribution. Background technique [0002] Among the lamps of the prior art, the lighting characteristics of coal mine centralized control room, oil field and factory area are large and wide. The lamps used at present are basically traditional lamps with metal halide lamps as light sources. Moreover, for large-area lighting environment, the existing technology is to use floodlights. Since it is full-circle lighting, most of the light is irradiated to the upper space, but not projected on the work surface, and the light projected on the wall of the upper space is not blocked. Utilization, that is, about 40% of energy is wasted, and the utilization rate of lamps is low. [0003] Therefore, there are defects in the prior art and need to be improved. Contents of the invention [0004] The technical problem to be solved by the present inven...
