Abstract

The invention discloses an LED lamp for a distribution box. According to the LED lamp for the distribution box, a connecting gap cannot exist between a lamp body and a light transmitting plate when the light transmitting plate is collided mistakenly. The LED lamp for the distribution box comprises the lamp body (1) and the light transmitting plate (2). An annular protrusion (3) is arranged at the end of the lamp body (1). A first annular elastic body (4), the light transmitting plate (2), a second annular elastic body (5) and the annular protrusion (3) are sequentially sealed and bonded from top to bottom. The outer side of the first annular elastic body (4) and the outer side of the second annular elastic body (5) are both sealed and bonded with the inner side face of the lamp body (1). The first annular elastic body (4) and the second annular elastic body (5) are made of the same materials, and the materials comprise, by weight, 40-45 parts of chlorinated polyethylene, 10-15 parts of natural rubber, 5-8 parts of butadiene-styrene rubber, 3-5 parts of aromatic hydrocarbon oil, 1-2 parts of anti-aging agents, 0.5-1.5 parts of sulphur and accelerant, 0.3-0.4 part of co-crosslinking agent, 0.5-2 parts of zinc oxide and 20-30 parts of carbon black.

Description

technical field [0001] The invention relates to the technical field of LED lamps, in particular to an LED lamp for a distribution box. Background technique [0002] Lighting is required in the distribution box, and LED lights are a better choice, such as "a distribution box for automatic lighting" with the publication number CN103500943A. Connection, when workers operate in the distribution box, it often happens that the light-transmitting board is accidentally hit by a human body or a tool, and the connection between the lamp body and the light-transmitting board will vibrate. Over time, the joint between the lamp body and the light-transmitting board will A gap will be generated, thereby destroying the seal between the lamp body and the light-transmitting plate, so that the service life of the LED lamp in the distribution box is relatively short. [0003] Existing patent documents, such as the Chinese patent application "A LED lamp" with the publication number CN103398364...
