Problems solved by technology
Therefore, many manufacturers make LEDs into fluorescent lamps. Since LED fluorescent lamps are scattered point light sources, when they are directly irradiated to human eyes, it is easy to cause glare; in order to avoid glare, people set lenses or lampshades on fluorescent lamps. The lampshade will reduce the lighting intensity, which will increase the LED power to overcome it, and also increase the cost

Embodiment
[0018] Example: such as figure 1 , figure 2 shown.
[0019] A reflective LED fluorescent lamp, comprising an arc-shaped heat dissipation substrate 3, one end of the heat dissipation substrate 3 is provided with a card slot 31, the opening of the card slot 31 faces the other end of the heat dissipation substrate 3, and a PCB board 2 is inserted into the card slot 31 , the PCB board 2 is provided with several LEDs, a light outlet is provided between the two ends of the heat dissipation substrate 3, and the light emitted by the LED is projected onto the inner surface of the heat dissipation substrate 3 and projected out from the light outlet. There are several protrusions or concave holes 34 for diffuse reflection, and this embodiment adopts the concave hole 34 structure.
[0020] When the technical solution is implemented, the LED light bar (PCB board 2 ) is inserted into the card slot 31, and the light emitted by the LED is reflected through the inner surface of the heat dis...

The invention relates to the technical field of LEDs, in particular to a reflective type LED fluorescent lamp. The reflective type LED fluorescent lamp comprises an arc heat dissipation substrate, wherein a clamp slot is formed in the inner side of one end of the heat dissipation substrate; an opening of the clamp slot faces the other end of the heat dissipation substrate; a PCB (printed circuit board) is inserted into the clamp slot and is provided with a plurality of LEDs; a light emitting port is formed between two ends of the heat dissipation substrate; light emitted by the LEDs is projected to the inner side surface of the heat dissipation substrate, is reflected and then is projected out from the light emitting port; a plurality of bulges or concave holes for diffuse reflection are formed on the inner side of the heat dissipation substrate. The heat dissipation substrate is designed in a light ray reflection mode, and the bulges or the concave holes for the diffuse reflection are formed, so that light rays projected out of the inner side surface of the heat dissipation substrate are uniform, glare is avoided, and the structure is simple.
Description
technical field [0001] The invention relates to the technical field of LEDs, in particular to a reflective LED fluorescent lamp. Background technique [0002] As a traditional lighting, gaze lamps are used in various occasions, such as offices, classrooms, etc. With the development of society, people pay more and more attention to energy, and LEDs, as cold light sources, have been widely used. Therefore, many manufacturers make LEDs into fluorescent lamps. Since LED fluorescent lamps are scattered point light sources, when they are directly irradiated to human eyes, it is easy to cause glare; in order to avoid glare, people set lenses or lampshades on fluorescent lamps. The lampshade will reduce the illumination intensity, which will increase the LED power to overcome it, and also increase the cost. Therefore, it is necessary to design a low-cost LED fluorescent lamp that can overcome glare. Contents of the invention [0003] The object of the present invention is to sol...
