Description

LED indirect lighting structure

The present invention is a technical field of LED indirect lighting fixture structure, in particular, a component group modeling design, which is convenient for manufacturing, storage and assembly, and can adjust the illumination light type.

A light-emitting diode is a kind of cold energy that converts electrical energy into light energy. The manufactured LED lamp has a service life of up to 100,000 hours under the condition of good heat dissipation, so the application field is very wide. With the popularity of the use, the size of such a light-emitting diode lamp is also increased and lengthened, so the use has the following disadvantages: 1. The light generated by the light-emitting diode is highly directional, and the user may directly cause direct vision. Disability glare. If the power of the diode is too large, I am afraid that the retina affects the visual acuity; 2. As the size of the lamp increases, the body must also be a rectangular body with a large length and a large width, which makes the body difficult to control in production and processing precision, and the difficulty is improved. Increase the production cost; 3. As the size of the luminaire increases, the number of components increases. Relatively, various components need more different processes and storage space in the preparation, storage and storage, which will increase the cost; The shape of the light exit of the luminaire will directly affect the illumination type. If the body is fixed, the output illumination type is fixed. If it is required to change the illumination light type, the shape of the body, the internal secondary optical reflector, etc. must be redesigned, thus increasing the time, difficulty and cost of product redesign.

The main purpose of this creation is to provide an LED indirect lighting structure, which mainly provides a modular structure design, which is convenient for production and rapid assembly; and can quickly change the shape of some components and adjust the output illumination type according to different requirements. .

The secondary purpose of this creation is to provide an LED indirect lighting fixture structure, which uses a double elliptical reflective surface to output a symmetrical light distribution curve, and places the LED on one of the focal points of the elliptical reflective surface, so that the indirect lighting fixture of the present invention has the maximum output light amount.

In order to achieve the above purpose, the LED indirect lighting fixture structure comprises: a body connector, two indirect optical reflectors, two LED light source panels, two first light exit angle adjusters and a plurality of second light exit angle adjusters . Two indirect optical reflectors are symmetrically disposed on both sides of the body connector. Each of the indirect optical reflectors is a long housing and has a semi-elliptical surface. The semi-elliptical surface has a first side and a second side opposite to each other, and the body connector is coupled to the first side. A top surface of each of the LED light source panels is partially coupled to the corresponding indirect optical reflector and is coupled to the first side. An LED light exit is formed between the LED light source panel and the second side. The LED light source board is further provided with a plurality of light emitting diodes on the top surface. The light-emitting diode can project light to face the semi-elliptical surface, and after being reflected, the light is emitted from the light exit port. Each of the first light exit angle adjustments has a first light reflecting surface. The first light exiting angle adjuster is fixed to the corresponding indirect optical reflector, and the first reflective surface is coupled to the second side. A plurality of second light exit angle adjusters are fixed to the body connector, and are located perpendicular to the first light exit angle adjuster, and the second light exit angle adjuster has two second light reflecting surfaces distributed at an acute angle.

In an embodiment of the present invention, the distribution position of the plurality of light-emitting diodes is at one of the focal points corresponding to the semi-elliptical surface.

In the embodiment of the present invention, the first reflective surface is at least one of a vertical surface, a sloped surface, or a curved surface, and the vertical height, slope or curvature of the first reflective surface is used to control a view angle.

In the embodiment of the present invention, the second reflective surface is a slope or a curved surface, and the vertical height, slope or curvature of the second reflective surface is used to control the viewing angle.

In an embodiment of the present invention, the semi-elliptical curved surface, the first reflective surface, and the second reflective surface are mounted with a high reflectivity film.

The LED indirect lighting fixture structure has the following specific effects when used:

1. The creative component is modularized, and the main components are reduced to five components: the body connector, the indirect optical reflector, the LED light source panel, the first light angle adjuster and the second light angle adjuster. In the initial production, manufacturing, and storage of materials, it is easier and lower in cost, and subsequent assembly and production are also convenient.

2. The components are mostly long and narrow structures, and the manufacturing precision is easy to control and is not easily deformed.

3. Indirect illumination mode, the light-emitting diode is located at one of the focal points of the semi-elliptical surface. Thereby, the light is reflected once, the loss of Luminous flux is reduced, and the point source is changed to be a surface light source, and the output light is softer.

4. The two semi-elliptical surfaces are arranged in a symmetrical manner, and the two light exits are located on the outer side, not in the middle position, so that the light reflected by the two elliptical curved surfaces can be fused to obtain an ideal symmetrical light type.

5. If the output illumination type needs to be changed, only the shapes of the first light exit angle adjuster and the second light exit angle adjuster need to be changed, and the remaining structures do not have to be changed, thereby reducing design difficulty and research and development costs.

The light-emitting diode 31 projects light toward the semi-elliptical curved surface 21. In the embodiment, the LED light source panel 3 is partially locked to the first joint section 22. An exit port 24 is formed between the LED light source panel 3 and the second side 212. The light-emitting diode 31 emits light toward the semi-elliptical curved surface 21, and is reflected by the light-emitting port 24 to emit light.

In the present creation, the light is reflected by the two semi-elliptical curved surfaces 21 to form a symmetrical light pattern, but in reality, it is necessary to adjust the required illumination range and illumination light type according to different needs, and this part is The first light exit angle adjuster 4 and the second light exit angle adjuster 5 are responsible.

The first light exit angle adjuster 4 is an elongated side casing and has a first reflecting surface 41 at an intermediate position. Each of the first light-emitting angle adjusters 4 is fixed to the corresponding indirect optical reflector 2 , and the first reflective surface 41 is coupled to the second side 212 .
