Description

Composition of light emitting elements

technical field

The utility model relates to a composition of light-emitting elements, in particular to a composition of light-emitting elements with light-emitting diodes as light-emitting elements.

Background technique

In the production process of traditional light-emitting elements, because copper metal is used as the shell to make light-emitting elements, direct visual inspection cannot be performed from the appearance of the metal when inspecting light-emitting elements. Even when light-emitting elements are directly inspected visually, due to the Emitting light sources can easily damage eyesight and cause danger, thus causing the risk that visual inspection is not easy. In addition, because the light-emitting element is small, it is necessary to use a finer and smaller condenser lens in order to be placed in the light-emitting element. However, because the shell is made of metal and the lens is made of plastic, the manufacturing tolerance of the plastic is large, and the plastic cannot be properly installed in the shell. , so that the manufacture of the light-emitting element is not easy, and there are also disadvantages such as easy deformation of the lens and insufficient precision.

Utility model content

The main purpose of the utility model is to provide a light-emitting element composition, because the lens and the housing are integrally molded and injected, so that the assembly process is simple.

The secondary purpose of this utility model is to provide a composition of light-emitting elements, because the lens and the housing are integrally molded and injected, so that the structural strength of the composition is relatively high.

Another object of the present invention is to provide a light-emitting element composition. The side material of the housing can be light-transmitting plastic, so it can be visually detected and provides high visual detection safety.

In order to solve the unsatisfactory problems of the prior art, the utility model provides a light-emitting element, which is mainly composed of a casing, a light-emitting element accommodated in the casing, and a lens located at the front end of the light-emitting element. The housing is in the shape of a hollow cylinder, and the lens is accommodated at one end of the hollow cylinder inside the housing and integrally molded and injected with the housing.

The beneficial effect of the utility model is that the provided light-emitting element composition is formed by integral molding and injection of the lens and the housing, so that the assembly process is simple and the structural strength of the composition is high.

Detailed ways

Since the utility model discloses a light-emitting element composition, the basic principles of the light-emitting source and the lens used in it are already understood by those with ordinary knowledge in the relevant technical field, so the following description will not be fully described. At the same time, the diagrams compared below express the structural representations related to the features of the present utility model, and do not and need not be completely drawn according to the actual size.

First please refer to FIG. 1 , which is the first preferred embodiment of the present invention, which is a cross-sectional view of a light-emitting element. The light emitting device composition 1 includes a casing 11 , a light emitting device 111 , a lens 112 and other structures. The shape of the above-mentioned housing 11 is a hollow cylinder and is made of a plastic material, wherein the light-emitting element 111 is accommodated in the housing 11, and a lens 112 is arranged at the front end of the light-emitting element 111, and the lens 112 is accommodated in the housing One end of the hollow cylinder in 11 is made of the same plastic material as housing 11. It is worth noting that the casing 11 and the lens 112 are produced by integral molding and injection, so the light-emitting element composition 1 will not cause the lens 112 to be properly installed in the casing because the wall thickness of the casing 11 is too thin or the strength is insufficient. Instead, the lens 112 is properly embedded in the casing 11 through integral molding. After the above-mentioned integral molding and injection of the housing 11 and the lens 112 are completed, the light-emitting element 111 can be placed into the housing 11 next. Glue makes it bond better. Therefore, the integral molding of the casing 11 and the lens 112 makes the structure of the light-emitting component 1 stronger and simplifies the assembly process therein.

In the above embodiment, the light-emitting element 111 is a light-emitting diode, and the light-emitting diode can be any one of laser diode, red light diode, green light diode, blue light diode, white light diode and ultraviolet light diode, wherein the light-emitting element 111 uses laser Diodes are best. The bottom of the light emitting element 111 is further connected with a circuit board 113, which can be externally connected to any product. In addition, since the side of the casing 11 is made of light-transmitting plastic material, side light detection can be directly performed visually, thereby providing higher detection safety.

Please refer to FIG. 2 , which is a second preferred embodiment of the present invention, which is a cross-sectional view of another light-emitting element. The light-emitting element composition 2 includes structures such as a housing 21 , a light-emitting element 211 , and a lens 212 . The shape of the above-mentioned housing 21 is a hollow cylinder and made of a plastic material, wherein the light-emitting element 211 is accommodated in the housing 21, and a lens 212 is arranged at the front end of the light-emitting element 211, and the lens 212 is accommodated in the housing. One end of the hollow cylinder in the body 21 is made of a plastic material different from that of the housing 21 . It is worth noting that the casing 21 and the lens 212 are produced by integral molding and injection, so the light-emitting element composition 2 will not cause the lens 212 to be properly installed in the casing due to the thickness of the casing 21 being too thin or insufficient strength. Instead, the lens 212 is properly embedded in the casing 21 through integral molding. After the above-mentioned integral molding and injection of the housing 21 and the lens 212 are completed, the light-emitting element 211 can be placed into the housing 21 next. Glue makes it bond better. Therefore, the integral molding of the housing 21 and the lens 212 makes the structure of the light-emitting component 2 relatively strong and simplifies the assembly process therein.

In the above embodiment, the light-emitting element 211 is a light-emitting diode, and the light-emitting diode can be any one of laser diode, red light diode, green light diode, blue light diode, white light diode and ultraviolet light diode, wherein the light-emitting element 211 uses laser Diodes are best. The bottom of the light-emitting element 211 is further connected with a circuit board 213, which can be externally connected to any product. In addition, since the side of the casing 21 is made of light-transmitting plastic material, side light detection can be directly performed visually, thereby providing higher detection safety.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the patent application rights of the present utility model; at the same time, the above description should be clear and implementable for those who are familiar with the technical field, so others do not depart from the present invention. Equivalent changes or modifications completed under the spirit disclosed by the utility model shall be included in the scope of the patent application.
