Problems solved by technology

When moving the reflector, on the one hand, in order to meet the needs of light projection, the reflector has a relatively large shape and volume, and requires a large space when moving, resulting in large volume, high cost and inconvenient use of the lamp; on the other hand , the existing focusing device is also more complex, using sliding transmission or rolling transmission, the operation is not stable, affecting the lighting effect

Abstract

The invention provides a focusing lamp which comprises a lamp shell, a big reflecting cup, a small reflecting cup coaxially arranged in the big reflecting cup in the same direction, and a light source extending from the axle center of the big and small reflecting cups. An adjusting rod parallel with the axis of the big and small reflecting cups is also fixed on the lamp shell; one end of the adjusting rod extends out of the lamp shell, and the other end of the adjusting rod is provided with an adjusting block in threaded fit with the adjusting rod; when the adjusting rod rotates, the adjusting block can axially move along the thread on the adjusting rod; and the small reflecting cup is fixedly connected on the adjusting block. In the invention, the small reflecting cup is placed on the adjusting block in threaded fit with the adjusting rod, the adjusting rod is rotated so that the adjusting block performs linear transmission on the thread of the adjusting rod and drives the small reflecting cup to linearly move along the axis to change the focusing state of the lights on the inner ring, thus, good condensation and floodlighting effects can be achieved, and the requirements on short-distance work lighting and long-distance projection lighting are met. The focusing structure has the advantages of simple structure, stable transmission and good focusing effect.

Description

technical field [0001] The invention relates to a lamp, more specifically, to a focusing lamp. Background technique [0002] Lamps with focusing function are often used in explosion-proof areas of petroleum, petrochemical, shipbuilding and other industries, as well as in military, public security, electric power, metallurgy, airports, railways, tunnels, industrial and mining enterprises and other operating sites. When working at night, the two functions of spotlight and floodlight can be realized by focusing, so that it can meet the needs of close-range work lighting and long-distance projection lighting. [0003] In the current focusing lamps, a focusing device is generally installed on the lamp, and the focus state of the light is changed by moving the reflector. When moving the reflector, on the one hand, in order to meet the needs of light projection, the reflector has a relatively large shape and volume, and requires a large space when moving, resulting in large volume...
