Description

A cold cathode compact fluorescent lamp

The utility model relates to a high-power, long-life and high-efficiency cold-cathode compact fluorescent lamp, which can directly replace common hot-cathode compact fluorescent lamps and tungsten bulbs, and is used for lighting and traffic lights.

At present, the cold-cathode compact fluorescent lamp of the prior art uses a sealed bulb, which is mainly used for heat preservation to increase the temperature of the fluorescent tube and improve efficiency. This structure is suitable for low-power lamps, such as lamps less than 5 watts. It is effective. But for high-power fluorescent lamps, because the bulb will generate a lot of heat, if the sealed bulb structure is used, the temperature of the lamp tube will rise very high, so its brightness, efficiency and life will be greatly reduced, and it may even fail to work normally. .

The purpose of the utility model is to overcome the above-mentioned shortcomings, and provide a cold-cathode compact fluorescent lamp which can be made into a high-power cold-cathode compact fluorescent lamp with high luminous efficiency and long service life.

The purpose of this utility model is accomplished through the following technical scheme, which includes at least one cold cathode fluorescent lamp bent into a certain shape, a bulb, a driver and its shell, and a lamp holder. The bulb is a The bulb shell with one end open, the cold cathode fluorescent tube is fixed on the bottom of the bulb shell and the top of the driver shell, the input end of the driver is connected to the external voltage through the lamp cap, and its output end is connected to the fluorescent tube. When the external voltage is connected, the output voltage of the driver can light the fluorescent tube.

The utility model can be provided with at least one through hole on the bulb with one end open, such as a series of circular or other shaped through holes, so that the air can circulate better, so as to increase the heat dissipation effect and make it possible to manufacture large Powerful, long-life, high-efficiency cold-cathode compact fluorescent lamps.

The bulb described in the utility model is made of plastic, glass or metal, and it is connected with the top of the driver casing, and the two can be two parts or one part.

The cold-cathode fluorescent tube that is at least bent into a certain shape is in the shape of a spiral or other shaped tube.

When the cold cathode fluorescent tubes are more than one or multi-layered tubes, each tube can have the same luminous color or different luminous colors such as red, blue, and green. It can be used for multi-color, color-changing or full-color lighting and display, etc.

The utility model can also be provided with at least one through hole on the driver casing, which can make the air circulate and make the driver dissipate heat effectively to ensure the normal operation of the driver.

Accompanying drawing is the structural representation of the utility model.

The utility model will be described in detail below in conjunction with the accompanying drawings: the accompanying drawing is a structural schematic diagram of an embodiment of the cold cathode compact fluorescent lamp of the present utility model. It includes at least one cold cathode fluorescent lamp tube 1 bent into a certain shape, and the figure shows an example of a spiral lamp tube. There are electrodes 2 at the two ends of each lamp tube, and a bulb 3 with one end open outside the lamp tube 1 , a driver 4 , a driver shell 5 and a lamp cap 6 . The bulb 3 is connected to the top 5a of the driver housing 5, and the two can be two parts, or can be made into one part. The fluorescent tube is fixed on the bottom of the bulb shell 3 and the top 5a of the driver housing, and the input end of the driver 4 is connected to the lamp holder 6 through the connecting wire 7 . The output terminal of the driver 4 is connected with the electrode 2 of the CCFL tube 1 through the connection line 8 . After the input voltage is turned on, the output voltage of the driver 4 can light the fluorescent tube 1 .

The bulb 3 shown in the figure is a cup-shaped bulb with one end open, and the shape of the bulb can also be conical, cylindrical or other shapes. The blister 3 with one end open may also have at least one through hole 10 . A series of circular through-holes are shown in the figure, and the shape of the through-holes may also be other shapes. The opening 9 and the through hole 10 mentioned above can make the air circulate well, so that the fluorescent tube can effectively dissipate heat, so that a high-power, long-life, high-efficiency compact cold-cathode fluorescent lamp can be made.

The bottom 3a of the bulb shell 3 is a high-reflectivity surface, which can reflect the light emitted by the fluorescent tube backward to the front, as shown in Figure 11, so as to improve the utilization rate of light. The other parts of the bulb 3 can be transparent or diffuse, and can also be all or part of the reflective surface, the figure shows an example of a partial reflective surface. Wherein the front part 3b of the bulb is transparent or diffuse, and the rear part 3c is a reflective surface. The reflective surface 3c can reflect the light to increase the intensity 12 of the outgoing light. The reflective surfaces 3a and 3c can be made of aluminum film or other high reflectivity materials. The bulb 3 can be made of plastic, glass or metal.

The cold cathode fluorescent lamp is at least one cold cathode fluorescent lamp bent into a certain shape, such as two or more layers of spiral or two or more cold cathode fluorescent lamps of other shapes. The multi-layer or multi-branch cold-cathode fluorescent lamps 1 can be of the same emission color or of different emission colors, such as red, blue, and green, so that they can be used for multi-color, full-color or color-changing lighting and display etc. In this case, there will be more than two input lines 7 of the driver, which are used to connect the voltages of different signals and control the cold cathode fluorescent lamps 1 of different colors, so as to realize the purpose of multi-color, color-changing or full-color lighting and display, which can be used for Lighting, displays and traffic lights, etc.
