Rotary lamp for adjusting irradiation range

Abstract

The invention discloses a rotary lamp for adjusting an irradiation range. The rotary lamp comprises a panel assembly, a lens assembly, a jacket, lamp beads and a heat radiator, wherein the lamp beadsare connected onto the heat radiator and are close to the lens assembly; the jacket is fixed on the lens assembly; the heat radiator is sheathed in the jacket in a rotary manner; stroke slot holes areformed in the jacket around the circumferential surface of the jacket; protrusions are arranged at positions corresponding to the stroke slot holes, on the outer surface of the heat radiator; the protrusions extend into the corresponding stroke slot holes; the protrusions slide along the stroke slot holes by rotating the heat radiator, so that the lamp beads do far-near displacement relative to the lens assembly, and further the size of the irradiation range is adjusted. According to the lamp, the stroke slot holes are formed along the circumferential surface of the jacket; with the design, under the condition that the sizes of products are identical, more adjusting points can be arranged in the stroke slot holes, and the adjusted irradiation range is wider; the heat radiator drives the protrusions to slide in the corresponding stroke slot holes, and higher flexibility is realized; the rotary lamp has the advantages of simple and reasonable integral structure and stability in use; inaddition, the distance between the lamp beads and the lens assembly is easy to adjust.

Description

technical field [0001] The invention relates to the technical field of lamps, in particular to a lamp for rotatingly adjusting the irradiation interval. Background technique [0002] At present, the lamps with adjustable irradiation range on the market are realized by changing the distance between the light source and the light outlet. The light source is set in the light outlet. The farther away from the light outlet, the smaller the irradiation area of ​​the light source. [0003] However, the existing lamps with adjustable irradiation intervals are pull-out, that is, the light source is placed at the bottom of the pull-out mechanism, and the pull-out mechanism expands and contracts in the sleeve to change the distance between the light source and the light outlet. : The lamp is installed vertically, and the drawing mechanism and the sleeve also need to be installed vertically. The position between the drawing mechanism and the sleeve is difficult to control, and an addit...

Problems solved by technology

[0003] However, the existing lamps with adjustable irradiation intervals are pull-type, that is, the light source is placed at the bottom of the pull-out mechanism, and the pull-out mechanism expands and contracts in the sleeve to change the distance between the light source and the light outlet. : The lamp is installed vertically, and the drawing mechanism and the sleeve also need to be installed vertically. The position between the drawing mechanism and the sleeve is difficult to control, and an additional locking device should be provided to fix the position of the drawing mechanism and the sleeve, such as : A pinball and a pinball hole are arranged between the drawing mechanism and the sleeve, and the cooperation between the pinball and the pinball hole locks the position between the drawer mechanism and the sleeve, and the number of pinball holes limits the lockability of the pinball The position, that is, the adjustable range is limited. These structures make the structure of the lamp more complicated, with many parts, which is not conducive to assembly, which greatly increases the cost of the lamp. Moreover, the structure is prone to failure and unstable use.
