The present invention discloses a light guide for an endoscope. The light guide for an endoscope is equipped with an optical fiber. The optical fiber has an input side tapered portion and an output side tapered portion. The input side tapered portion is a predetermined portion of the optical fiber that includes an input end into which the illumination light enters the optical fiber, and the core of the optical fiber having a shape that becomes thicker toward the input end in the light input side tapered portion. The light output side tapered portion is a predetermined portion of the optical fiber that includes an output end through which the illumination light is output, and the core of the optical fiber having a shape that becomes thicker toward the output end in the light output side tapered portion. The core diameter at the input end is greater than the core diameter at the output end.

The invention relates to an illumination device (100). The illumination device comprises a lamp tube (1) with two open ends, a light engine (2) arranged in the lamp tube (1), a carrier for carrying the light engine (2), and two end covers (3) for sealing the open ends. The illumination device (100) is characterized by further comprising a diffuser (4), wherein the carrier for carrying the light engine (2) is kept on the diffuser (4), and the diffuser (4) is kept on the inner wall of the lamp tube (1).

The invention provides a rotatable streetlamp which comprises a lamp holder, a lamp post and a rotating device. The rotating device comprises a power device, a transmission structure and a positioning lampshade. The power device can provide rotating power for the lamp holder, the transmission structure can achieve speed-reduction transmission, the positioning lampshade can limit the position of an internal structure and prevent the internal structure from being exposed to the sun and rain, the lamp holder is fixed to a rotary disc so as to swing along with the rotary disc, the light emitting face of the lamp holder is inclined downwards, and the rotary disc and the power device are connected to transfer power from the power device to the lamp holder.

The invention discloses an illuminating system and engineering machinery. The illuminating system comprises a power source device, a signal collecting device for collecting turn signals, a trigger device, a primary floodlight and auxiliary floodlights used for enlarging illuminating areas. The primary floodlight and the auxiliary floodlights are connected with the power source device, the trigger device is arranged on a connecting wire between the auxiliary floodlights and the power source device, the trigger device is connected with the signal collecting device and used for controlling the auxiliary floodlights to be turned on and turned off according to the turn signals, therefore, illumination blind zones existing during turn are eliminated, the visual field is enlarged, an operator can observe the working conditions of a zone in advance towards which a machine is turned, and operation efficiency is improved.

An LED illumination device comprises a lamp holder, a first radiator arranged on the lamp holder, a plurality of LED combinations, a plurality of second radiators arranged on the periphery of the first radiator, and a plurality of heat tubes connected with the first radiator and the second radiators, wherein the heat tubes comprises a heat absorb section and a heat release section, the heat absorb section is arranged in the second radiator, the heat release section is arranged in the first radiator, and the LED combinations are attached to the second radiators. The first radiator is additionally arranged on the LED illumination device to assist in dissipating heat, and the LED illumination device gains higher radiating efficiency and simultaneously can control the volume of the radiators; moreover, the LED combinations are attached to the second radiators which are arranged on the periphery of the first radiator, so rays can be radiated to the periphery of the illumination device, and the better illuminating effect can be realized.

The invention provides a lighting device for navigation. A containing space is formed in a ship body, a partition plate is arranged in the containing space, and the containing space is divided into asealed cavity and an operation cavity with an opening through the partition plate; a driving piece is located in the sealed cavity and comprises a first driving part and a second driving part; the first driving part is connected with a rotary disc, the second driving part is connected with the rotary disc, the lighting piece is arranged on the rotary disc and comprises a first lighting part and asecond lighting part, the first lighting part is arranged in the middle of the rotary disc, and the second lighting part and the first lighting piece are arranged at intervals. The first driving partdrives the rotary disc to rotate; due to the fact that the first lighting part is located in the middle of the rotary disc, the first lighting part can continuously light in the designated direction,the second lighting part is located at the eccentric position of the rotary disc, in the rotating process of the rotary disc, the second lighting part can rotate along with the rotary disc, the secondlighting part can conduct rotary lighting, and the lighting direction and the lighting area are increased.
