Detailed ways:

Below in conjunction with accompanying drawing, the utility model is further described.

The following descriptions are only preferred embodiments of the present utility model, and therefore do not limit the protection scope of the present utility model.

See accompanying drawing 1,2,3, it is the schematic diagram of the first embodiment of the utility model, as shown in the figure, the utility model comprises lamp tube 10, the first circuit board 20, cold cathode tube 30, diffuser 32, fluorescent Diaphragm 34, the lamp tube 10 is a hollow tube made of light-transmitting material; each side of the lamp tube 10 has an electric plug-in 80, and the electric plug-in 80 has two contact electrodes 82, the electric plug-in The specification of 80 is the same as the existing lamp tube at present, and the purpose is to make the lamp tube 10 of the present utility model can be directly inserted into the existing lamp holder for use; The first circuit board 20 is sandwiched between the opposite first card slots 40; a cold cathode tube 30 is installed on the first circuit board 20, and the cold cathode tube 30 can directly generate ultraviolet light; the diffuser 32 is installed on the lamp The inner wall of the tube 10 is located directly against the cold cathode tube 30. The fluorescent film 34 is installed in the lamp tube 10, close to the diffuser 32, and the position is between the diffuser 32 and the cold cathode tube 30. The fluorescent film 34 has a phosphor layer. When ultraviolet light is irradiated, the phosphor layer will be excited to generate visible light, and then the visible light will be diffused by the diffusion sheet 40. Because the lighting effect is far better than that of LED, and the number of cold cathode tubes 30 used is very small , can improve production efficiency, and also has the advantages of energy saving and environmental protection.

The lighting lamp of the utility model shown in the figure adopts a cold cathode tube 30 as a light source, and is made into a long tubular shape at the same time. The first circuit board 20 can be in the shape of a single strip, and the cold cathode tube 30 is installed on the first circuit board 20; Or the first circuit board 20 adopts two shorter plates, which are respectively located at the electrodes at both ends of the cold cathode tube 30, and can also bear the cold cathode tube 30; That is, the direction in which the first engaging grooves 40 are distributed in the lamp tube 10 is parallel to the central axis of the lamp tube 10 to support and fix the first circuit board 20 .

The lamp tube 10 also has a pair of opposite second card slots 50, a second circuit board 60 is installed between the second card slots 50, and the position of the second circuit board 60 in the lamp tube 10 is away from the cold cathode. Where the tube 30 is located, there is no contact between the first circuit board 20 and the second circuit board 60 and there is a certain interval, and only electric wires are used for electrical connection; the second circuit board 60 is equipped with a control circuit, including capacitors, resistors and other related lines, and are electrically connected with the first circuit board 20 and the electric plug-in 80 of the lamp tube 10; after the electric plug-in 80 is powered on, the second circuit board 60 drives the cold cathode tube 30 to light after voltage transformation and rectification; the first circuit The purpose of separating the plate 20 from the second circuit board 60 is heat insulation and insulation, so as to prevent the heat generated by the cold cathode tube 30 from being directly transferred to the second circuit board 60, causing damage to the circuits related to the second circuit board 60. , but also to achieve better insulation effect.

In addition, a fluorescent reflective sheet 36 is installed on the first circuit board 20. When the cold cathode tube 30 emits light, the ultraviolet light generated will excite the phosphor layer of the fluorescent reflective sheet 36 to generate visible light, and reflect the visible light to the diffusion sheet. 32 in the direction of the tube wall of the lamp tube 10 to increase the overall brightness.

In order to form the first clamping groove 40 and the second clamping groove 50 on the inner wall of the lamp tube 10, the following scheme is adopted: the inner wall of the lamp tube 10 is formed with a plurality of protrusions along the axial direction, and the protrusions include opposite Two upper protrusions 12, two middle protrusions 14, two lower protrusions 16, a first clamping groove 40 is formed between the upper protrusions 12 and the middle protrusions 14, and between the middle protrusions 14 and the lower protrusions 16 A second card slot 50 is formed.
