Description

Diffusion lens with compound lens {With desorption structure of the diffusion lens}

The present invention relates to a structure of a photodiode (LED) mounted and used in a package structure, a structure in which a reflector and a diffusion lens can be easily attached and detached, and a composite lens in a diffusion lens. The photodiode, which is combined with the metal PCB circuit and is mounted in a circle, also consists of a circle. The present invention relates to a diffusion lens having a built-in composite lens having a structure that is fitted by turning in a direction of about 20 degrees.

In general, a metal PCB light source used for LED lighting equipment is packaged with a number of power LEDs. Products such as street lighting and floodlights, for example, require the technology to reach light over long distances.

When a wide light source is needed using a photodiode, a large amount of high power photodiode is used to ensure the efficiency of the light source.

A large number of components of a high output photodiode should be applied. In this case, a heat sink having a large capacity is required depending on the temperature rising factor as well as the cost increase factor.

Therefore, in order to improve such a problem, LED lighting products incorporating lens technology are being developed in various ways.

However, the application of the lens requires technical problems due to cost increase factors and complex manufacturing processes.

The present invention was invented in view of the above-mentioned problems, and in order to increase the efficiency of the light source in the structure and the construction method thereof, cost reduction is achieved by simplifying the structure and work process of the photodiode (LED) and the lens. Its purpose is to maximize efficiency by providing easy to manufacture LED lighting device.

In the lighting device according to the present invention for achieving the above object in the circuit configuration of a metal PCB, including a photodiode (LED), in the lighting device of the reflector and the diffusion lens and the composite lens combined structure coupled to the metal PCB ,

On the circuit board of the metal PCB, several photodiodes (LEDs) are formed at regular intervals in a circle shape.

The structure of the reflector is combined with the circular reflector on the metal PCB, and the L-shaped groove is formed on the circumference to facilitate the detachment of the lens.

To be combined with the L-shaped grooves, the diffusing lens is circular and is formed by forming an intaglio groove at regular intervals on the rim.

The circular diffuser has a limiting jaw formed around its inner circumference, and includes a protruding portion on one side of its inner side, and a complex lens having a combination of concave and convex is embedded inside the diffuser.

The composite lens has a structure in which a protruding groove formed in the diffusion lens is combined with an intaglio groove for easy combination in one direction.

The lens coupling illumination device according to the present invention is a structure in which the photodiode forms a circular circuit and reaches a distance from the diffusion lens through the compound lens, and forms an L-shaped groove structure around the reflector, thereby providing a photodiode (LED). ) Structure is to be perpendicular to the composite lens and aspherical diffusion lens is combined with the reflector and the socket to maintain a constant distance to minimize the loss of light generated in the photodiode (LED),

Since a small amount of photodiode (LED) is applied, cost reduction can be realized through a simple production process.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

As shown in Figure 5 of the accompanying drawings of the present invention,
The reflector 2 coupled to the metal PCB 1 structure on which the photodiode 1b is mounted has an intaglio groove 2a formed at a predetermined interval on an outer circumference thereof, and an intaglio groove 4a formed at the edge of the diffusion lens 4. ) And the intaglio grooves 2a of the reflector 2 are formed around the L-shaped intaglio grooves 2b to facilitate mutual coupling and detachment.

At the inner circumference of the diffusing lens 4, the limiting jaw 4c and the projection 4b are formed at one side thereof and the combined lens 3 is coupled to the photodiode 1b on the bidirectional concave 3b surface. A plurality of hemispherical convex 6 surfaces are formed at the position to be provided.

In general, the circuit configuration of the metal PCB consists of a rectangular circuit, and the reflector forms a bolt and nut through a machining process using a CNC lathe machine made of aluminum, and the convex lens of the cross section is fastened by a nut. It is widely used.

Such a structure has a structure in which light efficiency is reduced because light generated from a rectangular photodiode is emitted through a circular lens in the circuit configuration.

Therefore, the lens generally has a circular or hemispherical structure, and is placed on the same line as the circuit structure of the metal PCB 1, so that the limit jaw 4c between the diffuser lens 4 and the composite lens 3 is formed. L-shaped groove 2b formed at the periphery of the reflector 2 and the engraved groove 4a of the aspherical diffuse lens 4 having the edges are combined to be positioned at

The composite lens 3 is composed of a bidirectional concave (3b) surface,

The composite lens 3, which is composed of a bidirectional convex 6 surface at the same position as the photodiode 1b on the bidirectional concave 3b surface, is combined with the diffuser lens 4 to form a L around the reflector 2. It is made of a structure that is inserted into the magnetic groove (2b) is rotated, coupled.
