Abstract

The utility model discloses a make luminous even LED bulb, including glass bulb main part, the even coating of bulb main part internal surface has one deck light scattering layer, the middle part of just penetrating directly the LED lamp in the bulb main part still is provided with one deck half -reflection coating, the half -reflection coating set up as center department to all around for light through the time transmission rise, reflect the layer structure of scribbling that reduces gradually. The utility model has the advantages of it is luminous even.

Description

Make luminous uniform LED bulb

Technical field

The utility model relates to lighting fixture, especially relates to a kind of luminous uniform LED bulb.

Background technology

In the market, LED is because its light source light-emitting efficiency is high, power consumption is little, long service life, security reliability are high and the advantage of energy-conserving and environment-protective and being used widely, as LEDbulb lamp.But along with the increase of LED quantity in LEDbulb lamp and the raising of power and brightness, LEDbulb lamp is greater than the light intensity of surrounding outgoing in the light intensity of the dead ahead outgoing of its direct projection, can cause non-uniform light.

Utility model content

For overcoming the shortcoming of prior art, the utility model object is to provide a kind of luminous uniform LED bulb.

The utility model is realized by following technical measures, one makes luminous uniform LED bulb, comprise glass bulb main body, described bulb body inner surface is evenly coated with one deck light diffusion layer, just one deck semi-reflective coating layer is also provided with to the middle part of LED direct projection in described bulb body, described semi-reflective coating layer is set to center to surrounding be light by time transmission raise gradually, reflect the coating structure reduced gradually.

As a kind of preferred embodiment, the dead ahead that described semi-reflective coating layer is positioned at LED direct projection becomes 10 degree to 15 degree places with glass bulb main body axis.

As a kind of preferred embodiment, described light diffusion layer is made up of light spread powder.

As a kind of preferred embodiment, also comprise the lamp holder being arranged on glass bulb body openings place and the LED lamp panel be arranged in lamp holder, described LED lamp panel is provided with LED.

As a kind of preferred embodiment, described LED lamp panel is aluminium base.

The utility model is provided with one deck semi-reflective coating layer in the middle part of LED direct projection, and this semi-reflective coating layer to be set to center to surrounding be light by time transmission raise gradually, reflect the coating structure reduced gradually, thus go out from other scattered through angles after making middle high light have part diffuse reflection (because also having one deck light diffusion layer), make light from LED bulb injection evenly.

Accompanying drawing explanation

Fig. 1 is the structural representation of the utility model embodiment.

Fig. 2 is the profile of the utility model embodiment.

Detailed description of the invention

Contrast accompanying drawing below in conjunction with embodiment the utility model is described in further detail.

One makes luminous uniform LED bulb 100, referring to figs. 1 to Fig. 2, comprise glass bulb main body 101, described bulb body 101 inner surface is evenly coated with one deck light diffusion layer 102, just one deck semi-reflective coating layer 103 is also provided with to the middle part of LED 200 direct projection in described bulb body 101, described semi-reflective coating layer 103 is set to center to surrounding be light by time transmission raise gradually, reflect the coating structure reduced gradually, be coated with semi-reflective coating layer 103 again as light diffusion layer 102 first can be coated with in the present embodiment.Also can first be coated with semi-reflective coating layer in other embodiments and be coated with light diffusion layer again, its illumination effect can not be affected.

This LED bulb is provided with one deck semi-reflective coating layer 103 in the middle part of LED 200 direct projection, and this semi-reflective coating layer 103 to be set to center to surrounding be light by time transmission raise gradually, reflect the coating structure reduced gradually, thus go out from other scattered through angles after making middle high light have part diffuse reflection (because also having one deck light diffusion layer 102), make the light that penetrates from LED bulb 100 evenly.

Making in the embodiment of luminous uniform LED bulb one, with reference to figure 2, the basis of previous technique scheme can also be specifically that the dead ahead that semi-reflective coating layer 103 is positioned at LED 200 direct projection becomes 10 degree to 15 degree places with glass bulb main body 101 axis.Become 10 degree to 15 degree cambered surface places to be the most strength of luminous intensity with axis, front, the transmission of the light of this cambered surface of a directive part gone out, another part reflects away, and makes its dead ahead evenly luminous, and by the light of reflection from the direction injection being greater than 180 degree, thus the lighting angle of the light that can also increase.

Make in the embodiment of luminous uniform LED bulb one, with reference to figure 2, the basis of previous technique scheme can also be specifically, and light diffusion layer 4 is made up of light spread powder.And light diffusion layer 4 is sprayed on carbon nanotube coating 5 surface, therefore adhesive force is larger, is not easy to drop.

Make in the embodiment of luminous uniform LED bulb one, referring to figs. 1 to Fig. 2, the basis of previous technique scheme can also be specifically, also comprise the lamp holder 400 being arranged on glass bulb 100 opening part and the LED lamp panel 300 be arranged in lamp holder 400, described LED lamp panel 300 is provided with LED 200.

Making in the embodiment of luminous uniform LED bulb one, the basis of previous technique scheme can also be specifically LED lamp panel 300 is aluminium base.Thus strengthen its heat dispersion.

More than to the utility model, luminous uniform LED bulb is set forth; the utility model is understood for helping; but embodiment of the present utility model is not restricted to the described embodiments; any do not deviate from the utility model principle under do change, modification, substitute, combination, simplify; all should be the substitute mode of equivalence, be included within protection domain of the present utility model.
