Description

A kind of LED bulb lamp shade

technical field

The utility model relates to a lampshade, in particular to a lampshade with an LED light source, which belongs to the technical field of semiconductor lighting. the

Background technique

In the current indoor lighting field, fluorescent energy-saving lamps are still the main products in the competition of traditional high-efficiency light sources, and have advantages that traditional light sources are difficult to match. However, under normal circumstances, it is a glass lampshade, which is fragile, difficult to transport and store, and will release harmful substances to endanger the environment. In addition, low-power LED energy-saving lamps also occupy part of the market. Although low-power light-emitting tubes have the advantage of low cost of light-emitting devices, when people design lampshades, the light-emitting shades are transparent PC plus frosted lampshades or acrylic plus toner. The light transmittance is low; the LED light source is a point light source, and the internal point light source can be seen, the illumination is uneven, and it may cause glare to the user; or the lampshade is coated or frosted to form diffuse reflection of light, but In this way, the light efficiency is greatly lost, and the above solutions more or less hinder the effective application of the lamps. the

Contents of the invention

In view of the defects of the above-mentioned existing technical solutions, the utility model provides a high-transmittance, high-diffusion, glare-free, and light-free LED bulb lamp shade, which uses high-quality light-diffusing PC lampshade to resist impact and not break, and improve its light intensity. Transmittance, reduce the loss of brightness, uniform diffusion of light, provide a production plan with simple process and low cost, and promote the rapid application and implementation of new technologies. the

The purpose of this utility model will be achieved through the following technical solutions:

A lampshade for an LED bulb lamp, characterized in that: the lampshade uses polycarbonate with a light transmittance of over 92% as a base material, and includes a relatively thick light-emitting part at the top and a mouth mounting part with gradually thinning edges. The overall shape of the lampshade includes at least hemispherical, spherical, cylindrical, and prismatic shapes, and the inner wall of the lampshade is frosted or provided with a light-enhancing coating; The ring snap groove or thread. the

Further, the polycarbonate of the LED bulb lamp shade is one of glass, resin or PC polymer material. the

Further, the inner surface of the light emitting part of the inner wall of the lampshade is a smooth spherical curved surface, or a frosted spherical curved surface, or a spherical curved surface provided with a light-enhancing coating. the

Further, the inner wall of the lampshade opening is provided with an annular reflective ring facing the light emitting part of the lampshade. The reflective ring is coated with a metal reflective layer; or coated with a monochromatic or colored, fluorescent powder reflective layer. Moreover, the annular reflective ring gradually becomes thinner along the cover wall toward the cover opening to form a rib. the

This kind of LED bulb lamp shade has obvious advantages and beneficial effects:

The utility model has reasonable structure, simple design, heat resistance, impact resistance, high flame retardancy, and easy molding; after effectively adjusting the diffusivity and light transmittance, the light source has excellent concealment, high light transmittance, high diffusion, and light transmittance. The efficiency can be 85-92%, so that the light emitted by the LED light source can be evenly diffused, without glare or shadow; realize the transformation of point light source into spherical light, and obtain excellent lighting effects, which are generally suitable for LED bulb lamps. use. the

Among them: 1~light emitting part, 2~installation part of the cover mouth, 3~reflective circle

Detailed ways

As shown in Figure 1 and Figure 2, the utility model provides a lampshade for an LED bulb lamp. The lampshade is translucent and includes a light emitting part 1 whose top is thicker relative to the mouthpiece and a mouthpiece installation part whose edge gradually becomes thinner. 2. The lampshade is made of polycarbonate with a light transmittance above 92%, and one of glass, resin or PC polymer material can be selected. the

The cover body of the LED bulb lamp shade is processed by injection molding, blow molding, molding, blow molding, extrusion, calendering, plating, etc., preferably using injection molding technology. The shape of the manufactured cover body at least includes hemispherical, spherical cylindrical, cylindrical and prismatic shapes, and the inner walls of lampshades of various shapes are completely or partially frosted or provided with a light-enhancing coating. The outer circumference of the open end of the lampshade is provided with an annular engaging groove or thread for connecting with the light source chamber of the lamp housing. the

As a preferred embodiment of the present invention, the inner wall of the lampshade is a smooth spherical surface on the inner surface of the light outlet part, or a diffuse reflection spherical surface formed by frosting, or is provided with a light-enhancing coating to reduce the glare of the lamp. Furthermore, the inner wall of the lampshade mouth is provided with an annular reflective ring 3, which is coated with a reflective layer made of metal, or a reflective layer made of phosphor powder, monochrome or colored, to reduce the loss of diffuse reflection and improve the LED performance. The light intensity of the lighting fixture. The outer wall is provided with a threaded structure or a buckle to fix the lampshade. The above-mentioned annular reflective ring can gradually become thinner along the cover wall toward the cover opening to form a rib, which can also facilitate the fixing of the lampshade and prevent the colloid used for connection and fixation. Excessive overflow, therefore, easier to install and maintain. the

To sum up, the LED bulb lamp shade is not only shatterproof, dustproof, anti-aging, but also has a frosted effect, uniform and soft light, no glare, high light output rate, simple processing method, safe and reliable; the above-mentioned LED bulb lamp shade Compared with incandescent tubes or low-voltage fluorescent tubes, the emitted light has a wider diffusion range, and is widely applicable to the light distribution of various indoor lighting fixtures. the

The above-mentioned embodiments only express several implementations of the utility model, and the description thereof is relatively specific and detailed, but it should not be construed as limiting the patent scope of the utility model. the
