Abstract

The utility model discloses a LED spotlight structure, which comprises a lamp shell provided with a heat dissipation device, an arc-shaped reflecting cup arranged in the lamp shell, and a cold LED light source arranged at the center of the arc-shaped reflecting cup and electrically connected with a constant-current stabilized-voltage power supply; and an optical convex lens is arranged above the cold LED light source. The optical convex lens can refract the LED illumination to the surface of the arc-shaped reflecting cup, and the illumination is provided outwards by the surface of the arc-shaped reflecting cup. The optical convex lens not only increases the area of a luminous object and improves the lighting effect, but also can make the illumination softer.

Description

An LED spotlight structure

technical field

The utility model relates to an LED spotlight structure.

Background technique

The spotlight is a typical modern lighting with no main lamp and no fixed scale, which can create an indoor lighting atmosphere. If a row of small spotlights are combined, the light can change into wonderful patterns. Because the angle of the small spotlight can be changed freely, the effect of combined lighting is also ever-changing. The light of the spotlight is soft, graceful and luxurious, and it can also be partially illuminated to enhance the atmosphere. However, the existing disclosed spotlight structure is not completely reasonable and scientific; it is prone to the defects of light shift and poor concentration of light. At the same time, the light concentrating effect is not good, and the luminous efficiency is low.

Contents of the invention

The technical problem to be solved by the utility model is to provide an LED spotlight with good light concentrating effect, high luminous efficiency and softer illumination. The utility model is achieved through the following technical solutions:

An LED spotlight structure of the present utility model comprises a lamp housing provided with a heat dissipation device, an arc-shaped reflector cup installed in the lamp housing, which is arranged in the center of the arc-shaped reflector cup and is electrically connected to a constant-current stabilized voltage power supply A cool-color LED light source; an optical convex lens is arranged above the cool-color LED light source.

Preferably, the optical convex lens is a hemispherical convex lens.

Preferably, the illuminating surface of the LED light source faces the hemispherical convex lens.

Preferably, the arc-shaped reflective cup is in the shape of a horn.

In the LED spotlight of the utility model, since an optical convex lens is arranged above the cool-color LED light source, the optical convex lens can refract the LED light onto the surface of the arc-shaped reflective cup, and the surface of the arc-shaped reflective cup provides illumination outward. The optical convex lens not only increases the area of the luminous object, improves the light effect, but also makes the light softer.

Description of drawings

For ease of description, the utility model is described in detail by the following preferred embodiments and accompanying drawings.

Fig. 1 is a schematic diagram of the structure of the LED spotlight of the present invention.

Detailed ways

As shown in Figure 1, a LED spotlight structure of the present utility model includes a lamp housing 1 with a heat dissipation device, an arc-shaped reflective cup 2 installed in the lamp housing 1, and is located in the center of the arc-shaped reflective cup 2 A cool-color LED light source 3 electrically connected to a constant-current regulated power supply; an optical convex lens 4 is arranged above the cool-color LED light source 3 . The optical convex lens 4 can directly focus the main light of the LED light source 3 and refract the LED light to the surface of the arc-shaped reflective cup 2, and the surface of the arc-shaped reflective cup 2 provides illumination to the outside. The optical convex lens 4 not only increases the area of the luminous object, improves the light effect, but also makes the illumination softer.

Wherein, the optical convex lens 4 is a hemispherical convex lens, and the illumination surface of the LED light source 3 faces the hemispherical convex lens. The arc-shaped reflective cup 2 has a trumpet-like structure, and the inner surface of the arc-shaped reflective cup 2 is provided with a parabolic reflective surface formed by the extension of a parabola that can reflect the light emitted by the optical convex lens 4 to a set angle range. The parabola is extended to form a parabolic reflective surface, which can uniformly reflect the light introduced by the optical convex lens 4 outward within a set angle range.

In the LED spotlight of the utility model, since an optical convex lens is arranged above the cool-color LED light source, the optical convex lens can refract the LED light onto the surface of the arc-shaped reflective cup, and the surface of the arc-shaped reflective cup provides illumination outward. The optical convex lens not only increases the area of the luminous object, improves the light effect, but also makes the light softer.

The above-described embodiment is only an example of the utility model, and is not used to limit the implementation and scope of rights of the utility model. All technical solutions that are identical or equivalent to the claims of the utility model should be included in the utility model. within the scope of protection.
