Abstract

The utility model relates to a ring-type fluorescent lamp with a lamp tube whose half part is exposed outside the lamp. The lamp is provided with a concave lamp holder on one face of a holder shell provided with the lamp tube whose one part is positioned in the lamp holder and is fixed. The light source of the front face of the lamp tube direct irradiates, the light source of the back face is reflected by the lamp holder, and therefore, the ring-type fluorescent lamp achieves the purpose of the light-gathering irradiation. The center of the ring-type fluorescent lamp can also be provided with other lamps or decorative pieces. The lamp has good illumination and low cost and can strengthen the decorative effect of the lamp.

Description

Ring-type fluorescent lamp

The utility model relates to a kind of fluorescent lamp tool.The outer naked annular daylight lamp of particularly a kind of fluorescent tube part.

Before the utility model was made, the light fixture of annular daylight lamp was made up of seat shell, fluorescent tube and lampshade usually.The one side that its shell is installed fluorescent tube is the plane, and fluorescent tube hangs under the plane.The light source of this light fixture is easily dispersed, and profile is not attractive in appearance yet, thereby need install lampshade additional with optically focused and decoration.But installing additional of lampshade influenced the irradiation degree, and increased cost.In addition, the outside of light fixture installs function and ornamental limitation that makes light fixture behind the lampshade additional.

The purpose of this utility model is that a kind of annular daylight lamp tool that can optically focused be beneficial to decoration again will be provided, to reduce cost and to enlarge the purposes of light fixture.

Technology of the present utility model is achieved in that the lamp holder shell is struck out parabolic shape or rectangle, hemispherical, triangle etc., at it front of annular lamp tube is installed, according to fluorescent tube size punching press one spill lamp socket, the cross section of this lamp socket can be parabola, truncated cone-shaped, rectangle, triangle etc.Tube face drops in the lamp socket, and is fixed.The first half light source direct irradiation of fluorescent tube, latter half of light source reflects by lamp socket, forms focus irradiation.

Following the utility model provides embodiment in conjunction with the accompanying drawings.

Fig. 1 is the utility model embodiment generalized section.

Fig. 2 is the utility model embodiment side schematic view.

Referring to Fig. 1, seat shell 1 adopts sheet iron punch forming or plastic injected die moulding.At the convex surface middle part that fluorescent tube 2 is installed, according to centers such as fluorescent tube sizes one circle spill lamp socket 3 is set, these lamp socket 3 cross sections are with semicircle or be slightly less than semicircle for well.Fluorescent tube 2 is located in the lamp socket 3, and fixing with finer wire 4.The front light source direct irradiation of fluorescent tube, back side light source are then by arc lamp socket reflecting condensation, to prevent the light source scattering.Ballast, starter etc. place in the back side groove of pedestal.Referring to Fig. 2, because fluorescent tube directly is located in the lamp socket on the housing, omitted outside lampshade, make annular lamp tube central authorities form the space.A little energy consumption electricity-saving lamp can be installed in this space.In addition, do not influencing under the irradiation degree situation, various decoration can hang in its central authorities.

The utility model simple structure, the irradiation degree is good, and can reduce product cost, strengthens ornamental.

Claims

1, a kind of annular daylight lamp is made up of seat shell, annular lamp tube and match appliance spare, it is characterized in that described seat shell is a paraboloid, and there is a spill lamp socket at this paraboloid convex surface middle part, and annular lamp tube is located in the spill lamp socket.

2, annular daylight lamp according to claim 1 is characterized in that the paraboloid of described seat shell also can be cuboid, Rotary-table, trigone.

3,, it is characterized in that the cross section of described spill lamp socket can be parabola, truncated cone-shaped, rectangle, triangle according to claim 1,2 described annular daylight lamps.
