Description

A kind of bulb lamp

Technical field

It the utility model is related to lighting technical field, more particularly to a kind of bulb lamp.

Background technology

As LED technology develops, various LED lamps are emerged in large numbers in the market, and the use of LED lamp is different from the past white Vehement lamp；But the light fixture of many people incandescent shape still accustomed to using, therefore occur not major general's LED on the market and do balling-up The shape of lamp is steeped, using screw socket as interface, uses and has much antique effect；However, this kind of light fixture is when in use, due to not having There is lens on light source to carry out light projection correction so that light projection distribution is not uniform enough, has influence on use.

Utility model content

The purpose of this utility model is to provide a kind of bulb lamp that can uniformly project in view of the shortcomings of the prior art.

To achieve the above object, the utility model uses following technical scheme：

A kind of bulb lamp, including the lamp socket and glass cover body being fixedly connected, control board is fixed with the lamp socket, control Circuit board processed electrically connects with lamp socket, and control board is connected with light source；The medial surface welding of the glass cover body has multistage use In to the irreflexive glass fiber of light progress；And the area of glass fiber cover glass cover body is more than the 70% of the area of glass cover body.

Pass through the medial surface welding glass silk in glass cover body in the technical program so that glass fiber is covered in glass cover body Interior, the making can together be completed in glass cover body manufacturing process, and glass cover body is carried out to blow silk.This is prior art, this In repeat no more.Glass fiber is covered on the medial surface of glass cover body in a section, is formed after light source is irradiated to glass fiber Diffusing reflection, so as to realize the uniform effect of projection.Control board and light source can be prior art.

Further, the light source includes LED string, and the LED string includes multiple LED light groups being arranged in parallel.

When in use, can withdraw deposit light fixture its colorful property, here there is provided multiple LED light groups being arranged in parallel, luminous When, can be alternately luminous；Different LED light groups can send out the light of different colours, i.e., each LED light group sends one kind and is different from The light of other LED light groups.

Further, control board is provided with EMC circuits and rectification circuit, and EMC circuits include common mode filtering circuit and difference Mould filter circuit, common mode filtering circuit include transformer L1, and differential mode filter circuit includes inductance L2 and electric capacity CX1；EMC circuits Zero line input is electrically connected by transformer L1 primary coil with one of input of rectification circuit, the live wire of EMC circuits Input is electrically connected by transformer L1 secondary coil with another input of rectification circuit, wherein, live wire input is successively It is connected by inductance L2, electric capacity CX1 with zero line input.

Rectification circuit can use full-bridge circuit.

Common mode filtering circuit also includes electric capacity CY1 and electric capacity CY2；Electric capacity CY1 and electric capacity CY2 are series at the two of rectification circuit Between individual input, and electric capacity CY1 and electric capacity CY2 connection end is grounded by inductance L3.

Differential mode filter circuit also includes electric capacity CY2, and two inputs of electric capacity CY2 both ends respectively with rectification circuit connect Connect.

The beneficial effects of the utility model：The utility model uses the welding multistage in glass cover body to be used for irreflexive glass Glass silk, and the area coverage of glass fiber is more than 70%, so that it is luminous more uniform.

Brief description of the drawings

Fig. 1 is the first structural representation of the present embodiment.

Fig. 2 is a kind of schematic diagram of glass lamp shade of the present embodiment.

Fig. 3 is EMC circuit diagrams.

Reference includes：

1 --- control board；2 --- glass cover body；3 --- lamp socket；4 --- light source；5 --- glass fiber.

Embodiment

The utility model is described in detail below in conjunction with accompanying drawing.As shown in Figure 1 to Figure 3.

Embodiment：A kind of bulb lamp, including the lamp socket 3 and glass cover body 2 being fixedly connected, control is fixed with the lamp socket Circuit board 1, control board 1 electrically connect with lamp socket, and control board 1 is connected with light source 4；The inner side of the glass cover body 2 Face welding has multistage to be used to carry out irreflexive glass fiber to light；And the area of glass fiber cover glass cover body 2 is more than cloche The 70% of the area of body 2.

Pass through the medial surface welding glass silk in glass cover body 2 in the technical program so that glass fiber is covered in cloche In body 2, the making can together be completed in the manufacturing process of glass cover body 2, and glass cover body 2 is carried out to blow silk.This is existing skill Art, repeat no more here.Glass fiber is covered on the medial surface of glass cover body 2 in a section, when light source 4 is irradiated to glass fiber After form diffusing reflection, so as to realize the uniform effect of projection.Control board 1 and light source 4 can be prior art.
