Description

LED spotlight

technical field

The utility model relates to the field of LED lighting, in particular to an LED spotlight.

Background technique

The spotlight is a kind of lighting fixture embedded in the ceiling, the light shoots down, and can be rotated to change the irradiation angle. It is widely used in hotels, western restaurants, coffee shops, offices, shopping malls, museums and home interior lighting. Because LED has the characteristics of mercury-free, non-toxic, non-electromagnetic pollution, no harmful rays, energy saving, environmental protection, and long service life, existing spotlights gradually use LEDs as light sources. However, because the light of LED is point light, the light is irradiated in a straight line. The central point light of the straight line is very strong, but the virtual light around the point light is very weak. If multiple LEDs are combined into a flat light source, The illuminance spot formed by the light emitted by the LED becomes the superposition of point light and virtual light, which is a mixture of strong and weak light. There will be deep and shallow spots and shadows. Working and studying in this light environment for a long time will cause serious damage to people's vision.

Therefore, how to realize an LED spotlight with uniform illuminance, no shadow, and no spots is a technical problem to be solved urgently in the industry.

Preferably, it also includes a face ring connected and fixed to the upper end of the lamp body, the face ring is fitted on the LED lens, and presses and fixes the LED lens to the LED light source.

Preferably, the face ring is fixed to the lamp body through threaded connection.

Preferably, the face ring is connected and fixed to the lamp body by snap-fitting.

Preferably, the lamp body is a frustum of a cone, a polyhedron, a sphere or a combination of a frustum of a cone, a polyhedron and a sphere, and a light source installation part is provided on the upper end surface of the lamp body, and the LED light source is installed and fixed on the light source installation part superior.

The LED spotlight of the present utility model adopts a single LED lamp bead as its LED light source, and the light spot produced by it is a whole light spot, which avoids the flat light source composed of dozens or nearly a hundred LEDs due to the light emitted by each LED. The illuminance spots formed by superimposing each other are uneven and have shadows. Moreover, an LED lens is covered on the LED light source, and the LED lens includes a convex lens and a reflective cup that are covered on the LED light source. The brightness of the light emitted by the beads can reach the brightness of the light emitted by the surface light source formed by the combination of multiple LEDs; and the reflector cup converts the large-angle light emitted by the LED lamp beads into the required angle range, so as to achieve the change of light distribution and uniform output. The purpose is to decompose the light generated by the LED lamp beads into numerous image points after the light distribution of the convex lens, and then form a surface light source with uniform illumination and no shadows, so that the light emitted by the LED lamp beads appears soft due to being dispersed. It simply and effectively solves the problem of glare, and has a protective effect on people's eyesight.
