The light-emitting device provided to realize the purpose of the utility model includes a light source device, a light guide strip and a reflective circle, the light guide strip is arranged at the focal point of the concave surface in the reflective circle, the light source device and the light guide connection.

In one embodiment, the light emitting device further includes a rubber sleeve, and the light source device and the light guide strip are connected through the rubber sleeve.

In one of the embodiments, the light source device is an LED lamp.

In one of the embodiments, the concave surface in the reflective ring is provided with a coating that increases light reflection.

In one of the embodiments, both the light guide strip and the reflective ring are ring-shaped.

In one embodiment, there are two light source devices, and two ends of the light source devices are respectively connected to the light guide strip.

In one of the embodiments, the curved section of the concave surface is parabolic.

Beneficial effects of the utility model: the utility model light emitting device can realize point light sources to emit light evenly, so that the lights of household appliances are uniform and diversified, so that it has a very good appearance, beautiful and diverse characteristics of decoration under the action of lights.

Description of drawings

In order to make the purpose, technical solution and advantages of the light-emitting device of the present invention more clear, the light-emitting device of the present invention will be further described in detail below in conjunction with specific drawings and specific embodiments.

Fig. 1 is the schematic diagram of an embodiment of the utility model light-emitting device;

FIG. 2 is a schematic diagram of light rays at section A of the light emitting device shown in FIG. 1 .

Detailed ways

An embodiment of the light emitting device of the present invention is shown in Fig. 1 to Fig. 2 .

The light emitting device of the utility model comprises a light source device 3, a light guide strip 2 and a reflective circle 1, the light guide strip 2 is arranged at the focal point of the concave surface in the reflective circle 1, the light source device 3 and the light guide Bar 2 is connected.

When the light source device 3 is turned on, the light guiding effect of the light guiding strip 2 makes the entire light guiding strip 2 evenly illuminated, and because the light guiding strip 2 is designed in the reflective ring The focal point of the inner concave surface of 1, so that the light emitted by the light guide strip 2 to the periphery hits the concave surface, and after being reflected by the concave surface, it emits light evenly.

Preferably, as an embodiment, the light emitting device further includes a rubber sleeve 4 , and the light source device 3 and the light guide strip 2 are connected through the rubber sleeve 4 .

Preferably, as an embodiment, the light source device 3 is an LED lamp.

Preferably, as an embodiment, the concave surface in the reflective ring 1 is provided with a coating that increases light reflection.

Preferably, as an embodiment, both the light guide strip 2 and the reflective ring 1 are ring-shaped.

The light is reflected by the concave surface to the center area of the circular ring, finally making the light emitting device emit light evenly.

Preferably, as an embodiment, there are two light source devices 3 , and two ends of the light source devices 3 are respectively connected to the light guide strip 2 .

Preferably, as an embodiment, the curved section of the concave surface is parabolic.

The parabola is y^2=2px, the focus is (p/2, 0);

Among them, y is a dependent variable, x is a variable, and p is a parameter. The value of p will affect the shape and size of the cup and the focus position, and this value will be determined according to the actual design needs. x>0, p>0.

FIG. 2 is a schematic diagram of light rays at section A of the light emitting device shown in FIG. 1 .

The light-emitting device of the utility model can realize the uniform light emission of the point light source, so that the lights of the household appliances are uniform and diversified, so that it has the characteristics of very good appearance, beautiful appearance and variety under the action of the lights.

The above-mentioned embodiments only express several implementations of the utility model, and the description thereof is relatively specific and detailed, but it should not be construed as limiting the patent scope of the utility model. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the scope of protection of the utility model patent should be based on the appended claims.
