Detailed Description

The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

The tunnel lamp with high safety as shown in fig. 1 and 2 comprises a mounting seat 1, a lamp holder 2 is fixed on the mounting seat 1, a light-transmitting plate 21 is arranged on the lamp holder 2 in a vertically layered manner, the light-transmitting plate 21 is annularly embedded on the lamp holder 2, a sleeve brush 22 is arranged on the lamp holder 2, the sleeve brush 22 is sleeved on the light-transmitting plate 21 in a sliding manner, a sliding groove 23 is arranged in the middle of one side of the lamp holder 2, sliding blocks 24 are arranged on two sides of the sliding groove 23, one ends of the sliding blocks 24 corresponding to the sliding grooves 23 are connected through springs 25, connecting rods 26 are hinged on the sliding blocks 24, the other ends of the connecting rods 26 are hinged on the corresponding sleeve brushes 22, a sliding rod 3 is fixed on the sleeve brush 22, the sliding rod 3 stretches into the mounting seat 1 in a sliding manner, a limiting head 31 is arranged at the end part of the sliding rod 3, a motor 11 is arranged in the mounting seat 1, and the motor 11 drives a connecting cam 12 and the cam 12 is abutted to the bottom of the limiting head 31.

As a preferred embodiment, an LED lighting lamp 27 is provided in the lamp socket 2.

As a further improvement, the bottom wall of the lamp holder 2 is provided with the heat dissipation holes 28, and the heat dissipation holes 28 can facilitate the discharge of the heat of the bulb of the LED lighting lamp 27 when the LED lighting lamp is used, so that the service life of the LED lighting lamp is prolonged.

Furthermore, the dustproof net 29 is disposed in the heat dissipation hole 28, so that the dustproof net 29 can prevent external dust from entering the lamp holder 2, thereby affecting the use of the LED lighting lamp 27.

The tunnel lamp with high safety can regularly brush dust accumulated on the light-transmitting plate of the lamp holder when being installed and used, so as to ensure the emission and use of the optical fibers of the illuminating lamp in the tunnel lamp.
