Problems solved by technology

Since the aluminum substrate is directly glued to the inner wall of the glass tube, the LED is far away from the center of the glass tube, and the light emitted by it is reflected many times on the inner wall of the glass tube, which increases the loss of light

Embodiment Construction

[0015] Specific embodiments of the present invention are described with reference to the above drawings.

[0016] The transparent glass tube LED straight tube lamp of the present invention adopts a new technology LED. This kind of LED uses a fully transparent material as the substrate, and the beam angle is close to or greater than 300°, which breaks through the limitation of heat dissipation volume and reduces the requirements for heat dissipation. There are two new technology LEDs called LED filaments available on the market. Optional, one is cylindrical thin strip LED filament 80, such as image 3 As shown in (d), 81 is a luminous body wrapped on a fully transparent material substrate, 82 and 83 are pins respectively; the other is a rectangular flat LED filament, and there are two types of rectangular flat LED filaments, one is single-ended power supply A rectangular flat LED filament 40, such as figure 1 As shown in (e), 43 is a fully transparent material substrate, 41 a...

Abstract

The invention discloses an LED straight lamp made of a transparent glass tube. The LED straight lamp comprises a transparent glass tube body (20) and two lamp holders (10 and 11). Both the transparent glass tube body (20) and the lamp holders (10 and 11) meet the specifications of an ordinary straight tube fluorescent lamp, and the lamp holders (10 and 11) are respectively adhered to two ends of the transparent glass tube body (20). The LED straight lamp made of the transparent glass tube can also be made by the glass burn sealing technology of the ordinary straight tube fluorescent lamp. LED lamp filaments are directly welded to welding platforms (33) of LED supports (31) in the middle of an aluminum substrate (30). The outside of the bottom cross section of the aluminum substrate (30) is circular arc shaped with the curvature matching with that of the inner side of the cross section of the transparent glass tube body (20). Enough height is to be reserved between the welding platforms (33) and the aluminum substrate (30) so that light emitted from the LED lamp filaments is orthogonal to the inner wall of the transparent glass tube body (20), light consumption brought by multiple reflections is reduced, and the beam angle of the LED straight lamp made of the transparent glass tube can reach more than 300 degrees.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to the technology of a transparent glass tube LED straight tube lamp. Background technique [0002] So far almost all LED light sources and lamps are used to replace various other existing light sources and lamps, and LED straight tube lamps are used to replace various straight tube fluorescent lamps. Most of the LED straight tube lamps in the prior art use a semicircular aluminum tube as the main structural part of the LED straight tube lamp, which is not only used for heat dissipation, but also used for installing the aluminum substrate and the driving circuit on which the LED is welded. Many low-power SMD LEDs are densely mounted on the aluminum substrate, and the driving circuit is generally stuffed in a semicircular aluminum tube. Due to the small cross-sectional area of ​​the aluminum tube, the development of the driving circuit is limited. In such a small cross-section, it ...
