Description

Reflector lamp capable of changing light-emitting angle

Technical Field

The utility model relates to a lighting device especially relates to shot-light.

Background

Spot lights are often used to shine a particular item, thereby highlighting the item. This requires that the light-emitting range of the spotlight is narrow, so that as much light as possible can be projected onto the object to be projected. However, the light-emitting angle of the LED light source is relatively large, so that the light-emitting angle needs to be adjusted by the lens to achieve the effect of converging light. However, this method requires an additional lens, and is difficult to assemble and relatively expensive.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a shot-light is provided, need not just can change the luminous angle of LED light source through lens.

In order to solve the technical problem, the utility model provides a can change shot-light of luminous angle, include: the light-emitting device comprises a main body, a light-reflecting cup and a light-emitting cover; the LED lamp comprises a main body, a through cavity, a lamp cap, an LED light source and a driving circuit board, wherein the main body is axially provided with the through cavity; the light reflecting cup is arranged on the side wall penetrating through the cavity, extends along the circumferential direction of the side wall and surrounds all the LED light sources; the light outlet cover is arranged at the upper end of the through cavity;

the light reflecting cup is provided with a plurality of rows of rhombic lattices, each row of rhombic lattices extends along the circumferential direction of the light reflecting cup, and two adjacent rows of rhombic lattices are arranged in a staggered mode.

In a preferred embodiment: the rhombus lattice is arranged on one surface of the reflection cup facing the LED light source, and the surface of the reflection cup back to the LED light source is a plane.

In a preferred embodiment: the LED light sources are distributed on the substrate in concentric circles.

In a preferred embodiment: the lateral wall of the through cavity is provided with threads at the upper end along the circumferential direction, and the light outlet cover is connected with the main body through the threads.

Compared with the prior art, the technical scheme of the utility model possess following beneficial effect:

the utility model provides a can change light-emitting angle's shot-light, reflection of light cup's inner wall comprises multirow rhombus check to the rhombus check are electroplated into the mirror surface effect, and each rhombus check can all form a reflection of light face like this, thereby realize going out light concentrated reflection, realize need not to set up lens and just can reach required spotlight effect and change light-emitting angle. The light-emitting angle can be reduced by more than 20 degrees on the original basis by the mode, and the light efficiency can be improved by 15-20%.
