LED straight-tube lamp

Abstract

The invention discloses an LED straight-tube lamp comprising a lamp tube, a lamp cap, a power source and a lamp panel, wherein the lamp cap is arranged at one end of the lamp tube; the power source is arranged in the lamp cap; the lamp panel is arranged in the lamp tube and is provided with a light source; the light source is electrically communicated with the power source through the lamp panel; and the lamp panel is a flexible circuit board of which the end part is provided with a light source pad, and holes are formed in the light source pad. The flexible circuit board is directly welded at the power output end of the lamp cap, so that the quality problem caused by conducting wire migration breakage generated by a wire bonding way in the production, transportation and use processes can be avoided.

AI Technical Summary

Problems solved by technology

[0016] First, the lamp board is generally a rigid board. When the lamp tube is broken, especially when it is partially broken, the entire LED fluorescent lamp is still in a straight tube state. Users will mistakenly think that the lamp tube can still be used, so they can install it by themselves. It is easy to cause leakage and electric shock accidents

[0017] Second, in the existing LED straight tube lamps, metal wires are generally used to achieve electrical connection between the rigid lamp board and the lamp holder through wire bonding. Broken due to moving, resulting in quality problems

[0018] Third, in the existing LED straight tube lamps, hot melt adhesive or silica gel is usually used for bonding between the lamp cap and the lamp tube. If glue is used, it will affect the appearance and cause shading problems; if you want to remove excess glue, you need to use a lot of manual wiping in the later stage of the manufacturing process, which will affect the output

[0019] Fourth, the lamp tube in the prior art is generally a uniform cylinder, and the lamp cap is set outside the lamp tube and bonded with the lamp tube by glue. Therefore, the outer diameter of the lamp cap is larger than that of the lamp tube

However, compared with the direction from the outside to the inside, the glass tube can bear less force from the inside to the outside, so under the same force conditions, this LED straight tube lamp is easier to break

[0020] Fifth, in the existing LED straight tube lamps, the light source is a plurality of LED grains arranged on the lamp board. For each grain, because of its point light source characteristics, it has not undergone appropriate optical treatment, and the entire The light in the lamp tube is not uniform, so when the user observes the lamp tube from the outside, it has a grainy feeling, which affects the visual comfort; and it is impossible to see the light emitted by the light source from other angles, which has a defect in the viewing angle

However, the setting of the diffuser tube adds an interface to the propagation path of light, which will increase the probability of total reflection of light during propagation and reduce the output efficiency of light

In addition, due to the suction and rotation of the diffuser tube, the light output efficiency will also be reduced.
