Description
Technical field
The utility model is related to LED filament technical field, more particularly to the LED filament that a kind of anti-blue light is revealed.
Background technology
Present LED captures rapidly whole illumination market, and variously-shaped LED is also developed rapidly, uses
LED blue chips excite traditional red green two color fluorescent material, and more than 80 are extremely difficult in warm colour temperature colour rendering index.
Blue light can be produced by being additionally, since LED, if blue leakage, and easily the eyes of user are damaged.
Utility model content
The utility model embodiment solves blue light in the prior art by providing the LED filament that a kind of anti-blue light is revealed
Leakage, damages the technical problem of eyes of user.
In order to solve the above-mentioned technical problem, the utility model embodiment provides the LED filament that a kind of anti-blue light is revealed, bag
Substrate, the pad of substrate positive and negative, several LED chips, metal terminal are included, several LED chips are connected to base by pad
On plate, the hollow out lamp bracket for setting LED chip is covered in several LED chip overhead, and metal terminal is arranged at substrate two ends, in the LED
Fluorescent adhesive layer is coated between chip and pad, the phosphor powder layer of mixed light and luminous intensity distribution is coated with the hollow out lamp bracket, in institute
State also to be coated with outside metal terminal and absorb the fluorescence coating that blue light is converted to the colour temperature visible ray in addition to blue light.
Further, the hollow out lamp bracket includes covering at the first hollow out supporting plate of substrate front side and to cover at substrate anti-
The second hollow out supporting plate in face.
Further, the mixed light and the phosphor powder layer of luminous intensity distribution coated on the hollow out lamp bracket is located on the inside of hollow out lamp bracket.
Further, the hollow out lamp bracket is transparent material
The one or more technical schemes provided in the utility model embodiment, at least have the following technical effect that or excellent
Point：
Due to using fluorescent adhesive layer is coated on the pad of several LED chips and substrate connection, being set in LED chip outer cover
The hollow out lamp bracket of LED chip, coats the phosphor powder layer of mixed light and luminous intensity distribution, the metal end in substrate both sides on the inside of the hollow out lamp bracket
It is also coated with absorbing the fluorescence coating that blue light is converted to other colour temperature visible rays outside sub, by protecting layer by layer, absorbs blue light, it is to avoid blue
Light is leaked.
Brief description of the drawings
Fig. 1 is the structural representation of the LED filament of anti-blue light leakage in the utility model embodiment.
Embodiment
The utility model embodiment solves blue light in the prior art by providing the LED filament that a kind of anti-blue light is revealed

Art scheme is described in detail.
The utility model embodiment provides the LED filament that a kind of anti-blue light is revealed, as shown in figure 1, including substrate 10, base
The pad 101 of the positive and negative of plate 10, several LED chips 102, metal terminal 103, several LED chips 102 pass through pad 101
It is connected on substrate 10, the hollow out lamp bracket 20 for setting LED chip is covered in several overhead of LED chip 102, metal terminal 103 is arranged at
The two ends of substrate 102, are coated with fluorescent adhesive layer 104 between the LED chip 102 and pad 101, are coated with hollow out lamp bracket 20
The phosphor powder layer 201 of mixed light and luminous intensity distribution, other colour temperature visible rays are converted in the outer absorption blue light that is also coated with of metal terminal 103
Fluorescence coating 105.By protecting layer by layer, the leakage of blue light can be avoided.
In a particular embodiment, the hollow out lamp bracket 20 include cover at the positive first hollow out supporting plate of substrate 10 and
Cover at the second hollow out supporting plate of the reverse side of substrate 10.
The mixed light and the phosphor powder layer of luminous intensity distribution coated on the hollow out lamp bracket 20 is located on the inside of hollow out lamp bracket.
Specifically, the hollow out lamp bracket 20 is transparent material.So as to ensure the complete printing opacity of lamp bracket.
Although having been described for preferred embodiment of the present utility model, those skilled in the art once know substantially
Creative concept, then can make other change and modification to these embodiments.So, appended claims are intended to be construed to bag
Include preferred embodiment and fall into having altered and changing for the utility model scope.
Obviously, those skilled in the art can carry out various changes and modification without departing from this practicality to the utility model
New spirit and scope.So, if these modifications and variations of the present utility model belong to the utility model claim and
Within the scope of its equivalent technologies, then the utility model is also intended to comprising including these changes and modification.
