Description
Technical Field
The utility model belongs to the technical field of the LED illumination, concretely relates to low radiation linear light source device of uniform lighting.
Background
At present, no existing linear light source exists in the LED light source, and only the LED single-point light source can be arranged to form the linear light source, so that the linear light source emits light unevenly, and the brightness of the whole light intensity area is uneven. In order to make up for the defect, the existing solution is to improve the intensity of the whole LED light source to make the light source have excessively high intensity and dazzling, so that the eyes are easily burnt and the vision is affected.
SUMMERY OF THE UTILITY MODEL
The prior art is difficult to satisfy people's needs, in order to solve the above-mentioned problem that exists, the utility model provides an evenly luminous low radiation linear light source device can simply convert current LED single-point light source to various evenly luminous linear light sources, and luminous body luminous intensity is even, and light is hindering eye light wave such as blue light when absorbing the medium through transparent in addition and is kept apart by effective absorption, is difficult for causing the injury to eyes.
In order to achieve the above object, the utility model provides a following technical scheme:
the utility model provides an even luminous low radiation linear light source device, includes the base plate and installs the LED lamp on the base plate, is located LED lamp one side be equipped with the reflection stratum on the base plate, be equipped with the lamp shade on the reflection stratum, be equipped with the transparent wave medium in the lamp shade, and the lamp shade surface is equipped with the inhomogeneous printing opacity coating of transmittance.
The installation angle of the LED lamp and the reflecting layer is 90 +/-5 degrees.
The reflecting layer is a coating or a reflecting sheet.
The transparent wave-absorbing medium is a medium capable of effectively absorbing and isolating eye-damaging light waves such as blue light emitted by an LED light source.
The light-transmitting coating is coated on the light rays on the outer surface of the lampshade, and the transmittance of the light-transmitting coating is increased along with the dimming of the surface brightness of the lampshade.
Compared with the prior art, the beneficial effects of the utility model are that:
the light is being hurt eyes light wave such as blue light when absorbing the medium through transparent and is kept apart by the effective absorption, is difficult for causing the injury to eyes, sets up the inhomogeneous printing opacity coating of transmittance on the lamp shade surface simultaneously, carries out further control with the light source that gives off, makes the more even that the light source gived off.
Drawings
Fig. 1 is a schematic view of a front view structure provided by the present invention;
the reference numbers in the figures illustrate: 1-substrate, 2-LED lamp, 3-reflecting layer, 4-lampshade, 5-transparent coating and 6-transparent wave medium.
Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further explained by combining with the specific drawings.
It should be noted that, in the present invention, when an element is referred to as being "fixed" to another element, it may be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not denote a unique embodiment.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Example 1
Referring to fig. 1, a low-radiation linear light source device with uniform light emission includes a substrate 1 and an LED lamp 2 mounted on the substrate 1, a reflective layer 3 is disposed on the substrate 1 and on one side of the LED lamp 2, a lampshade 4 is disposed on the reflective layer 3, a transparent wave medium 6 is disposed in the lampshade 4, and a transparent coating 5 with non-uniform transmittance is disposed on the surface of the lampshade 4.
The installation angle of the LED lamp 2 and the reflecting layer 3 is 90 +/-5 degrees.
The reflecting layer 3 is a coating or a reflecting sheet
The transparent wave-absorbing medium 6 is a medium capable of effectively absorbing and isolating eye-damaging light waves such as blue light emitted by an LED light source.
The transparent wave-absorbing medium 6 is an acrylic material.
The light-transmitting coating 5 is coated on the outer surface of the lampshade 4, and the light transmittance of the light-transmitting coating 5 is increased along with the dimming of the surface brightness of the lampshade 4.
Because the angle of LED lamp transmission, the different region of light and shade can appear on 4 surfaces of lamp shade, and the design of the 5 transmittances of printing opacity coating makes 4 surfaces of lamp shade dark regional printing opacity coating 5 transmittances big, makes it darken slightly with the bright regional printing opacity coating 5 of 4 surfaces of lamp shade can effectual absorption partly light source messenger simultaneously to it is even to guarantee that the light source that holistic 4 surfaces of lamp shade dispersed.
The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
