Description

A kind of LED downlight

technical field

The utility model relates to an LED light source lamp, in particular to an LED downlight.

Background technique

LED downlight is a product improved and developed on the basis of traditional downlights with new LED lighting sources. The existing technology generally uses wafer chips and aluminum heat sinks, which have high heat dissipation. It has the following advantages: energy saving, low carbon, long life, good color rendering, fast response. The design of LED downlights is more beautiful and light. When installing, it can maintain the overall unity and perfection of architectural decoration without destroying the setting of lamps. The light source hides the interior of architectural decoration, the light source is not exposed, and there is no glare. The human visual effect is soft and uniform. However, the existing technology cannot take into account both the irradiation intensity and safety at the same time.

Contents of the invention

The problem to be solved by the utility model is to provide an LED downlight with simple structure, high safety factor and good lighting effect.

In order to solve the above problems, the utility model provides an LED downlight, which includes a base, an LED light source and a lamp tube. The base is provided with a power adapter, and the lamp tube includes an inner layer lamp tube and an outer layer lamp tube. An LED control core board is provided between the inner lamp tube and the outer lamp tube, and the LED control core board is connected to the power adapter through wires. The inner lamp tube is provided with an LED light source and a reflector, and the LED The light source and the reflector are arranged alternately, the lamp tube is provided with a lampshade, the lamp tube is provided with a clamp strip, the clamp strip has a through hole, the lampshade is provided with a clamp column, and the clamp column is connected to the through hole. holes to match.

As a further improvement of the utility model, a heat dissipation silica gel layer is provided on the inner surface of the cavity formed between the inner lamp tube and the outer lamp tube, and a connecting substrate is provided in the cavity for fixing the LED control core board. The reflective mirror is a concave mirror or a flat mirror.

As a further improvement of the utility model, the LED light source is composed of several light beads, and the light beads form a ring layer, and reflectors are arranged between the adjacent ring layers. A glossy layer is provided on the surface of the inner lamp tube to increase the intensity of irradiation.

Compared with the prior art, the utility model has the following advantages.

The LED downlight of the utility model has the advantages of simple structure, reasonable design, high safety factor and increased lighting effect, and is suitable for mass production. Since the inner lamp tube is provided with an LED light source and a reflector, and the LED light source and the reflector are arranged alternately, the irradiation light of the LED light source will increase the irradiation intensity every time it passes through the reflector. Since the inner surface of the cavity formed between the inner lamp tube and the outer lamp tube is provided with a heat-dissipating silicone layer, avoiding safety accidents caused by excessive temperature in the lamp tube, and because the cavity is provided with a connecting substrate for fixing the LED control The core plate ensures the overall stability of the structure. Since the LED light source is composed of several light beads, and the light beads form a circle layer, reflectors are arranged between the adjacent circle layers, and the reflectors are also a circle layer, which enhances the reflected light in all directions. The inner lamp tube A glossy layer is provided on the surface to increase the irradiation intensity. The lampshade can adjust the irradiation angle, and can be closed during transportation to protect the inside of the lamp tube and avoid collisions.
