Description

A kind of LED crystal light

Technical field:

The utility model relates to an LED lighting fixture, in particular to an LED crystal lamp.

Background technique:

The lamp base of the existing crystal lamp is usually set upwards, so that most of the light emitted by the lamp head is irradiated upwards on the ceiling or the wall, and the light emitted by the light source cannot be effectively used, resulting in a large waste of electric energy.

At the same time, due to the high power of commonly used crystal lamps, generally between 300W-600W, the power consumption of lamps increases sharply. The user has a high electricity bill and does not use it frequently. The crystal lamp in most families loses its original lighting function and becomes an ornament.

In addition, the divergence of the light source of the crystal lamp has no directionality, and most of the downward light directly passes through the lamp arm or decorative parts and irradiates the user's eyes. Long-term exposure will cause the user to dizzy, damage the user's eyes, and form light pollution; only A small part of the light irradiates on the crystal decoration and forms a light and shadow effect through the transmission or refraction of the crystal decoration. However, due to the single light source, the crystal decoration only emits light locally, which cannot create a crystal clear luminous effect.

Invention content:

The purpose of the utility model is to provide an LED crystal lamp. It has the advantages of simple structure, energy saving and power saving, and good light and shadow effect.

The technical scheme of a kind of LED crystal lamp described in the utility model is realized like this:

A kind of LED crystal lamp is characterized in that: it comprises:

A lampshade, a plurality of reflective surfaces are formed on the lampshade;

An LED light source assembly, including several LED light sources arranged inside the lampshade, and the reflective surface is located on the light path of the light emitted by the LED light source;

A hanger, the hanger is arranged at the opening at the bottom of the lampshade, and several crystal decorations are hung under the hanger.

Compared with the prior art, the LED crystal lamp described in the utility model has the following advantages:

1. By using the LED light source to replace the light source of the existing crystal lamp, at the same time, the reflective surface on the lampshade is used to reflect the light emitted by the light source, and the upward light is reflected to the bottom of the lamp, and the light energy is utilized to the greatest extent, so that the same lighting can be achieved The intensity only needs to use less light sources, reducing the energy consumption of lamps by more than 70%, saving more electricity and energy, and enhancing the practicality of crystal lamps;

2. Since there are several reflective surfaces on the lampshade, the light of each LED light source is reflected by the lampshade to form multi-channel reflected light, and then irradiated to the crystal decoration by converging to form transmission and refraction effects, so that the crystal decoration forms multiple lights. The part is more bright and clear, which not only makes the lamp itself more beautiful, but also beautifies the light and shadow effect of the lighting environment.

Each of the above-mentioned reflective surfaces is a square-shaped arc surface with a protrusion in the middle. The reflective surface of the lampshade is a curved surface, which is beneficial for the lampshade to scatter the light of the LED light source, so that the original point light source or line light source becomes a surface light source after reflection and scattering, and each reflective surface effectively illuminates the crystal decoration under the hanger , so that the crystal decoration has more light-emitting parts and is more transparent; at the same time, the light source is softer after being scattered, which will not cause dizziness to the user and can effectively protect the eyes.

The above-mentioned lampshade includes an upper part and a lower part. Both the upper part and the lower part are provided with reflective surfaces, and the sizes of the reflective surfaces of the upper part and the lower part increase successively from top to bottom. If the lampshade is taken as a whole, the area of the reflective surface increases sequentially from the top to the bottom of the lampshade. If the lampshade is too large, the reflective surface below is too large. The utility model divides the lampshade into an upper part and a lower part, and the area of the reflective surface increases gradually from the top of the upper part and the lower part from top to bottom, which can effectively reduce the area of the lower reflective surface to ensure that more reflective surfaces reflect light from the light source And scattering, not only can soften the light, but also enhance the luminous effect of the crystal decoration.

The above-mentioned LED light source assembly includes a light source installation seat, and the light source installation seat forms several installation surfaces along the vertical direction on the side wall, and the LED light source is arranged on the installation surfaces. The light of the LED light source is mostly emitted along the horizontal direction, which can avoid the dizziness caused by the light of the LED light source directly entering the user's eyes.

The above-mentioned LED light source includes an LED substrate and a plurality of LED lamp beads arranged on the LED substrate, and the LED substrate is arranged on the installation surface through heat dissipation paste.

The aforementioned LED lighting unit further includes a chassis arranged on the hanger, the projection of the chassis on the horizontal plane is larger than the projection of the light source mounting base on the horizontal plane. The chassis can include a hollow cavity for placing circuit components, and at the same time, the chassis can effectively block the light emitted directly from the LED light source to avoid light spots in the lighting environment.

The above-mentioned light source mounting base forms a heat-gathering channel in the middle, and the light source assembly also includes a heat dissipation device. The heat-dissipating device includes a heat-dissipating channel corresponding to the heat-gathering channel. .

The inner wall of the above-mentioned heat-gathering channel is provided with a first stud, the inner wall of the heat dissipation channel is provided with a second stud corresponding to the first stud, the lampshade is provided with a through hole corresponding to the first stud, and the lampshade passes through the screw. It is fixed between the light source mounting base and the cooling device.
