Description

Lens-refracting LED lights for better brightness

technical field

The utility model relates to an LED lamp, in particular to a lens refracting LED lamp capable of producing better brightness.

Background technique

LED is the most commonly used LED light source today. Because LED has various advantages such as power saving, small size, high efficiency, and great plasticity, all industries are currently committed to using LEDs to make their products more energy-saving and more efficient. Efficient.

However, although LEDs have high unit brightness, the light emitted by them is directional, so the light emitted by conventional LED bulbs is not uniform and has a small range. As far as indoor lighting is concerned, conventional LED bulbs are not ideal. For example, although LED bulbs installed on the ceiling can illuminate the area under the bulb, the corners of the ceiling or the parts around the bulb are obviously dim. It is extremely unsatisfactory for indoor light sources, so it is a pity that conventional LED bulbs still cannot replace traditional lamps.

Therefore, if a kind of LED light bulb with extensive lighting and high brightness can be proposed, it will be able to bring more convenience.

Contents of the invention

The purpose of the utility model is to solve the technical problem that the light of the existing LED light source has directivity, the illumination is uneven and the range is small.

In order to achieve the above purpose, the utility model proposes a lens-refracting LED lamp that can produce better brightness, including: a casing, the casing has an accommodating space for accommodating other components; and the bottom of the casing Shrink, forming a connecting portion for connecting to an external power supply; at least one LED light source, the LED light source is accommodated in the housing; and the LED light source is connected to a lens; wherein the LED light source Connect the connecting parts through a wire; wherein when the light emitted by the LED light source is projected out of the lens, the light path forms a truncated cone, and when the cone angle Θ of the truncated cone is an angle of 15°-50°, the best result is obtained. good lighting.

The beneficial effect of the utility model is that the light emitted by the LED light source can be made more uniform and the illumination range is larger.

The features and advantages of the present utility model can be further understood from the following description, and please refer to the accompanying drawings when reading.

Detailed ways

Hereby, with regard to the structural composition of this case and the effects and advantages that can be produced, in conjunction with the drawings, a preferred embodiment of this case is described in detail as follows.

Please refer to Figure 1A, which is a structure diagram of the LED lamp with a cup-shaped appearance of the present invention, showing that the lens refraction LED lamp of the present invention can produce better brightness, including the following components:

A casing 1, the casing has an accommodating space for accommodating other components; and the bottom of the casing is retracted to form a connecting portion 10 for connecting to an external power supply;

At least one LED light source 2, the LED light source is accommodated in the housing; and the LED light source is connected to a lens 20; the lens material is glass or plastic;

The LED light source 2 is connected to the connecting portion 10 through a wire (not shown in the figure), and the LED light source 2 is an LED light source.

Fig. 1B is the optical path diagram of the LED lamp shown in Fig. 1A, when the light emitted by the LED light emitting source is projected out of the lens in the utility model, the optical path forms a truncated cone, and the cone angle of the truncated cone is Θ angle, when The best illumination can be obtained when the Θ angle is an angle of 15°-50°.

The number of LED light-emitting sources described in the present invention can be increased or decreased according to requirements, and the arrangement can be changed as needed, and is not limited to the quantity or arrangement shown in the above description and drawings.

As shown in Figure 1A, the light source has a cup-shaped appearance, and there is a plane above it, and a plurality of LED light sources are arranged on the plane (three LED light sources are shown in the figure), according to the design and configuration of the present invention, the The LED light source and the corresponding lens make the light emitted by the LED light source projected through the lens, the conical angle Θ of the frustum of the projected light path is between 15 degrees and 50 degrees, so the best good lighting.

As shown in Figure 2A, the lamp source has a cylindrical appearance, wherein the lamp holder of the lamp body forms a cylinder, and a plurality of LED light sources are arranged along the surface of the cylinder, and Figure 2B is an LED as shown in Figure 2A The light path diagram of the lamp, according to the design and configuration of the present invention, the LED light source and the corresponding lens make the light emitted by the LED light source projected through the lens, the conical angle Θ of the frustum of the projected light path Between 15 degrees - 50 degrees, so get the best lighting.

The main purpose of the present invention is to determine the angle relationship between the LED light source and the installed lens, so that the projection angle Θ is between 15 degrees and 50 degrees, regardless of the shape of the lamp body.
