Description

Jack type LED light source with long afterglow luminescence function and luminescence mark with light source dot matrix

Technical Field

The utility model relates to a luminous optical device and light emitting apparatus field, concretely relates to socket type Led light source and have luminous sign of this light source dot matrix with long afterglow luminous function.

Background

The long afterglow luminescent material, also called luminous material, is a photoluminescence material: under the excitation of a light source, visible light is emitted, part of the obtained light energy is stored, after the excitation is stopped, the energy is slowly released in the form of light, and the luminous brightness of the luminescent material is related to the performance of the luminescent material and the thickness of the long afterglow luminescent layer and the concentration of the long afterglow luminescent powder in the luminescent material; due to the continuous development and progress of the Led combined with the long afterglow technology, the luminous brightness of the long afterglow material is greatly improved, which is gradually paid attention in the years, is applied to various light emitting equipment fields, is popular with markets and consumers, forms industry and local standards, and has already formed industrialized development.

Compared with the traditional photoelectric identification product, the long afterglow photoelectric identification product in the prior art can not only save energy consumption by intermittently exciting the long afterglow, but also continue to provide weak light indication, induction and illumination by afterglow luminescence when an electrical element is damaged or power is cut off, and has the advantages of incomparable security.

However, the long afterglow material is basically arranged in a plane covering manner by combining with the Led, mainly formed by liquid pouring and leveling, mainly takes a layered form, the Led is arranged below or inside the long afterglow material, the Led has a good light emitting effect only in an SMD (surface mount device) type Led, the light emitting effect of the Led in other packaging manners is not ideal, part of light energy excites the long afterglow when the Led emits light, and part of unconverted light energy is scattered and emitted through the long afterglow light emitting layer, so that the product in the prior art has the following defects:

1. the long afterglow adopts a plane covering arrangement mode, so that the long afterglow excitation in the Led direct projection direction (the main light axis direction of light emission) is sufficient, the light emission brightness is high, the long afterglow excitation in the other parts is insufficient, the light emission brightness is low, the total light emission is uneven, and the waste of the long afterglow light-emitting material is caused.

2. Because the long afterglow adopts a plane covering arrangement mode, the existing long afterglow photoelectric marking product can only emit light in a surface light emitting mode, and the application range is limited, for example, the dynamic light emitting effect is difficult to realize.

3. Due to the limitation of the prior art and the prior art, a large-size long-afterglow photoelectric identification product or a long-afterglow photoelectric identification product with a specific shape and a specific pattern is difficult to manufacture, and corresponding dies need to be customized temporarily, so that the cost is high, and the manufacturing process and the later maintenance are inconvenient.

Therefore, an Led long-afterglow composite luminescent lens is innovatively proposed, and the patent number CN 202110344517 is accepted and popularized by the industry, but the details of the structure of the Led long-afterglow luminescent body specifically used for assembling and fixing the panel mark are not described.

4. Because the long-afterglow luminescent layer is arranged above the Led, the Led luminescent layer is absorbed and scattered by the long-afterglow powder when being emitted through the long-afterglow layer, which causes the light intensity loss of Led emergent light to be overlarge and the directivity to be poor (the emergent light loses the directivity), and the light path design is difficult to achieve the aims of emitting parameters such as a luminous angle, a beam angle or light intensity distribution and the like, such as condensation, diffusion or deflection (an emergent main beam and a luminous main shaft are emitted in an acute angle) or polarization (sometimes called side light, the emergent light energy distribution of one side is larger than that of the other side) and the like, especially, the luminous device can not meet the requirements of fixed point (area) projection with illumination purpose or directional (angle) projection with indication purpose, and the existing product has short luminous range and short sight distance, the device is particularly not favorable for the requirements of long sight distance for traffic, security, emergency and other purposes, and the application range is limited.

5. The long afterglow luminescent layer covers the Led, and the Led emits light through the long afterglow luminescent material as mixed color light with the long afterglow excited light, resulting in impure luminescent color and chromaticity shift, so that the influence and interference on luminescent spectra of Led luminescent device chromaticity or color temperature are too large when the long afterglow excited light is caused, and the luminescent and luminescent spectra of the original Led are influenced: when the white light Led corresponding to the illumination purpose is used as an excitation light source, the spectrum quality of the white light is seriously influenced, and when excitation light sources of other colors are adopted, luminescent chromaticity is influenced, so that the application range is limited.

In short, the long afterglow luminescent products in the prior art have the fatal defects and other defects, restrict the development of the products and become a difficult problem to be solved urgently in the industry.
