BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to fluorescent lamps for illumination, and more particularly, to compact fluorescent lamps in which the lamp body is entirely transmitted.

Cover fluorescent lamps currently on the market generally consist of a lamp cover, a lamp tube, an intermediate plate, a ballast installed on a circuit board, a rear cover and a base. The lamp tube is fixed to the front end of the middle plate, and the circuit board of the ballast is installed at the rear of the middle plate, and the ballast is connected to the lamp tube and the base respectively, and the middle plate and the circuit board are located at the contact portion of the lamp cover and the rear cover. It is sealed inside the space, the lamp tube is accommodated in the lamp cover, the ballast is accommodated in the rear cover, and the base is fixedly installed at the distal end of the rear cover. Only the lamp cover is made of transparent or translucent material, The lamp cover allows the light emitted from the lamp tube to be projected. The rear cover is made of an opaque plastic material to cover the internal ballast and to unify the appearance of the exterior. Therefore, since the rear part of the cover type fluorescent lamp is formed by the shielding of the plastic rear cover, on the one hand, it is difficult to sufficiently satisfy the aesthetic appearance of the lamp, and at the same time, the light output used for lighting is also lost. In addition, current commercial cover-type fluorescent lamps are generally large in volume and are not suitable when relatively small volumes and dimensions are required.

It is an object of the present invention to provide a fully translucent covered fluorescent lamp that can project light emitted from a lamp tube, except for the base.

It is a second object of the present invention to provide a fully translucent covered fluorescent lamp which is small in volume, compact and can project the light emitted from the lamp tube by the entire lamp except the base.

The object of the present invention is realized in the following configuration.

The fully flood-covered fluorescent lamp includes a lamp cover made of a light-transmitting material, a lamp tube, an intermediate plate, a ballast installed on a circuit board, a rear cover and a base, and the lamp tube is fixed at the front end of the intermediate plate and at the rear end of the intermediate plate. Fix the circuit board on which the ballast is installed. The ballast is connected to the lamp tube and the base respectively. The intermediate plate and the circuit board are sealed in the space at the contact portion of the lamp cover and the rear cover, and the lamp tube is accommodated in the lamp cover, and the ballast is accommodated in the rear cover. Install the base at the distal end of the rear cover. The intermediate plate, the circuit board and the rear cover are made of a translucent material so that the light emitted from the lamp tube by the rear of the fluorescent lamp can be projected from the rear cover via the intermediate plate and the circuit board, or the circuit board and the intermediate plate are perpendicular to each other. The rear cover and the lamp cover together constitute a translucent lighting housing by preventing the light emitted from the lamp tube from being emitted from the rear cover through the intermediate plate even if the circuit board is not transmitted, thereby preventing the light from projecting from the rear cover via the intermediate plate.

In a preferred configuration, the intermediate plate is made of transparent PC plastic, the circuit board is made of transparent fiber board material, and the rear cover is made of transparent PC plastic to which colored powder is added.

Further, the intermediate plate is parallel with the circuit board and the degree to which the circuit board is projected on the axis of the entire fluorescent lamp is smaller than the degree to which the lamp tube is projected on the axis of the whole lamp.

If a diaphragm is required, a diaphragm made of a light-transmitting material is installed between the circuit board and the intermediate plate in parallel, and the degree to which the diaphragm is projected on the entire axis of the lamp is smaller than that of the lamp tube is projected on the entire axis of the lamp. .

The second object of the present invention is realized through the following technical means on the basis of the above arrangement.

The axis of the lamp tube and the entire axis of the lamp overlap, and the distal end is joined to the intermediate plate front end. Ballasts manufactured by chip processes using small volume components and chip elements allow the partial components to be inserted into the base interior space.

In another embodiment, the axis of the lamp tube and the entire axis of the lamp are perpendicular to each other and the lamp tube is fixed to the front end of the intermediate plate with a metal clip. Ballasts manufactured by chip processes using small volume components and chip elements allow the partial components to be inserted into the base interior space.

The fully translucent covered fluorescent lamp of the present invention should unify the appearance of "exterior appearance commonly used in the industry for many years, must cover the inner ballast, and manufacture the rear cover with an opaque material. No need to be taken into consideration ", the middle plate fixing the lamp tube, the diaphragm and the circuit board of the ballast which isolate the conductors are made of light-transmitting material, and the rear cover is also made of light-transmitting material, The intermediate plate, the diaphragm, and the circuit board were penetrated and projected to the rear cover. At the time of lighting, since the light is transmitted to the rear cover, the entire lamp emits light when viewed from the outside. This spreads more light from the lamp tube, improving the lighting effect. The rear cover adopts PC plastic to add an appropriate amount of colored powder so that the light transmitting performance is excellent but opaque. When the electric current does not flow, the rear cover can cover the internal stabilizer and unify the appearance aesthetic. The ballast will be difficult to see. For example, when the milky white powder is added to make the rear cover milky white, the spreading light is not only softer but also matches the color tone of the lamp cover to further increase the aesthetic effect. In particular, when the fully translucent covered fluorescent lamp of the present invention is used among the lighting fixtures, it is possible to sufficiently express the aesthetics and lighting effects of the lighting fixture by removing the dark parts that the conventional covered fluorescent lamps could not solve. In the structure, if the circuit board of the ballast is mounted vertically in the rear of the middle plate, or if the middle plate and the circuit board are parallel, the design of the circuit board is projected on the whole axis of the lamp is smaller than the lamp tube is projected on the whole axis of the lamp. It is possible to further increase the light emitting amount of the rear cover. Furthermore, it adopts an installation structure in which a compact lamp tube of SLU or SL or 3U improved or 4SL structure is directly bonded to the intermediate plate, or a compact lamp tube of 2SL structure and a metal clip are installed in the intermediate plate, When combined with a ballast manufactured by a chip process using a component and a chip element, such that the partial component is inserted into the base internal space, it is possible to effectively shorten the length and diameter of the overall lamp using the internal space.
