Problems solved by technology

[0006] The technical solutions disclosed above only use structural improvement to realize the connection between the lamp body and the light-transmitting plate, which is not suitable for the impact situation. However, the impact situation cannot be avoided. The board is damaged or there is a gap in the connection between the lamp body and the light-transmitting board

Embodiment 1

[0042] Light-transmitting plate material composition: 100 parts of polyvinyl chloride resin (YH-2500 polyvinyl chloride resin: S-700 polyvinyl chloride resin = 8:1), 2 parts of stabilizer (CZ-001 stabilizer), lubricant (GH -104) 0.5 parts, coloring agent (ultramarine powder) 0.001 parts, impact modifier (MBS) 3 parts, dioctyl phthalate 3 parts.

[0043] The material method of the above-mentioned transparent plate of the present invention is:

[0044]1 According to the proportion of the formula, add the raw materials into the kneader and mix evenly, and knead for 8-20min at a temperature of 95-120°C;

[0045] 2 Then discharge the kneaded mixture, stir and cool to 35-40°C;

[0046] 3. Put the material into the granulator for twin-screw extrusion and granulation. The temperature of the screw extruder is 120-180°C;

[0047] 4 Then add the extruder to extrude the sheet. The barrel temperature of the extruder is 150-190°C, and then enter the pressure roller to extrude the material...

Embodiment 2

[0049] Polyvinyl chloride resin (YH-2500 polyvinyl chloride resin: S-700 polyvinyl chloride resin = 10:1) 100 parts, stabilizer (TM-181 type) 3 parts, lubricant (GH-104) 1 part, coloring Agent (ultramarine powder) 0.0015 parts, impact modifier (MBS) 4 parts, dioctyl phthalate 4 parts.

[0050] The preparation method is the same as in Example 1.

Abstract

The invention discloses an LED lamp used for a distribution box. When a transparent board is struck, the transparent board has a buffering effect, so that the probability of damage to the transparent board is reduced, and no gap is formed when a lamp body is connected with the transparent board. The LED lamp comprises the lamp body (1) and further comprises the elastic transparent board (2), wherein the outer annular side face of the end of the lamp body (1) is covered with the inner annular side face of the transparent board (2), and the end face (3) of the end of the lamp body (1) is attached to the inner bottom surface of the transparent board (2). The transparent board (2) is composed of, by weight, 100 parts of pvc resins, 2-3 parts of stabilizing agents, 0.5-1 part of a lubricating agent, 0.001-0.0015 part of a coloring agent, 1-4 parts of impact modifiers and 2-5 parts of dioctyl phthalate.

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, not only the light-transmitting board is easily damaged, but also the connection between the lamp body and the light-transmitting board will vibrate. A gap will be generated at the joint between the body and the light-transmitting plate, thereby destroying the seal between the lamp body and the light-transmitting plate. The above situation makes the service life of the LED lamp in the distribution box shorter. [0003] Existing patent documents, such as the Chinese patent application "A...
