Lamp with adjustable irradiation angle

Abstract

The lamp with the adjustable irradiation angle comprises a shell, and a spring sliding block positioning mechanism and a radiator are arranged in the shell. The radiator is connected with a light source, and a plurality of positioning holes distributed in a semicircular or arc shape are formed in the side edge of the radiator. The spring sliding block positioning mechanism is arranged on the side edge of the radiator and comprises a longitudinally-arranged first sliding block and a transversely-arranged second sliding block. One end of the first sliding block is exposed out of the shell, and the other end abuts against a first spring; one end of the second sliding block is clamped into the positioning hole, and the other end abuts against the second spring; when the part, exposed out of the shell, of the first sliding block is pushed, the first sliding block extrudes the second sliding block, the end, clamped into the positioning hole, of the second sliding block is made to move out of the positioning hole, and the radiator rotates within the preset angle range. According to the technical scheme provided by the utility model, the irradiation effect of a full-cut-light wall lamp and a half-cut-light wall lamp can be met by only one set of mold, so that the product development cost is reduced, and the requirements of more use scenes can be met.

Description

Technical Field

[0001] The utility model relates to the field of wall lamps, in particular to a lamp with adjustable irradiation angle. Background Art

[0002] With the development of science and technology, LED wall lamp technology is also developing continuously, bringing various conveniences to our lives. Existing wall lamps are mainly divided into two types: full-cut light and half-cut light. Full-cut light wall lamps shine light downward at a 90° vertical angle, while half-cut light wall lamps emit light at a forward tilt angle. At present, most designs of full-cut light wall lamps and half-cut light wall lamps on the market cannot be universal. For manufacturers, the mold cost and labor cost of developing two types of lamps at the same time are huge, and the economic benefits are not high. Therefore, it is necessary to make structural improvements to reduce costs and increase efficiency. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, the utility model provides a lamp with adjustable illumination angle, which has the illumination effects of both a full-cutoff wall lamp and a half-cutoff wall lamp, which not only reduces product development costs but also can meet the needs of more usage scenarios.

[0004] A lamp with adjustable illumination angle, comprising a housing, wherein a spring slider positioning mechanism and a semicircular or arc-shaped heat sink are arranged in the housing; a light source is connected to the heat sink, and a plurality of positioning holes distributed along a semicircle or an arc are arranged on the side of the heat sink;

[0005] The spring slider positioning mechanism is arranged at the side of the radiator, and comprises a first slider arranged longitudinally and a second slider arranged transversely; one end of the first slider is exposed from the housing, and the other end is abutted against the first spring; the first slider moves longitudinally within the travel range of the first spring; one end of the second slider is inserted into the positioning hole, and the other end is abutted against the second spring; the second slider moves transversely within the travel range of the second spring;

[0006] When the first slider is pushed to expose the portion of the housing, the first slider squeezes the second slider, so that the end of the second slider inserted into the positioning hole is moved out of the positioning hole, and the heat sink rotates within a preset angle range.

[0007] Preferably, the number of the first spring is one or more;

[0008] Preferably, the preset angle range is from -30° to 60°;

[0009] Preferably, the first slider is provided with a convex column for abutting against the first spring; the second slider is provided with a positioning column for engaging with the positioning hole; the first slider and the second slider have wedge-shaped contact surfaces abutting against each other;

[0010] Preferably, the second sliding block is provided with a hole for accommodating the second spring;

[0011] Preferably, a power module is also provided in the shell.

[0012] The utility model provides a lamp with adjustable illumination angle, in which a spring slider positioning mechanism is arranged on the side of a semicircular and arc-shaped heat sink, and the working principle is as follows: when the first slider is pushed or pressed to expose the portion of the shell, due to the mutual squeezing of the two sliders, the second slider moves laterally toward the outside and escapes from the positioning hole, so that the radiator can rotate within a preset angle range, thereby driving the light source to rotate, thereby achieving the illumination effect of a full-light-cutoff wall lamp and a half-light-cutoff wall lamp; when the first slider is released, the first spring returns the first slider to the initial position, and the rebound force of the second spring causes the second slider to be stuck in the positioning hole at the target illumination angle, thereby achieving fixed illumination angle.

[0013] Compared with the existing technology, only one set of molds is needed to meet the illumination effects of full-cutoff wall lamps and half-cutoff wall lamps, which not only reduces product development costs but also meets the needs of more usage scenarios. BRIEF DESCRIPTION OF THE DRAWINGS
