Embodiment Construction

[0034] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific embodiments.

[0035] Please compare figure 2 with image 3 As shown, it is a comparison between the prior art and the technical solution of the present application. In the prior art, the LED fluorescent lamp 100 further includes a housing 6 and a PC cover 7. The housing 6 and the PC cover 7 can be buckled with each other and Then a cavity 61 is formed, and the circuit board is accommodated in the cavity 61. Specifically, in this embodiment, the circuit board is composed of a first substrate 1 and a second substrate 2, that is, the first substrate 1 and the second substrate 2 are contained in the cavity 61; because the existing LED fluorescent lamp 100 diverges light at 120 degrees, but the PC cover 7 does cover half of the entire housing 6, that is, covers an angle of 180 degrees, which will be separated on both sides Form ...

Abstract

The invention discloses an improved structure for a light emitting diode (LED) lamp tube, which comprises a case and a polycarbonate (PC) cover, wherein the case and the PC cover can be mutually buckled for forming an accommodating cavity, a circuit board is accommodated in the accommodating cavity, a plurality of LEDs are arranged on the circuit board in the length direction of the circuit board, the covering angle of the PC cover is the same as the illumination angle required by light rays, and in addition, each LED arranged on the circuit board is respectively distributed in a direction vertical to the length direction of the circuit board. On one hand, each LED on the circuit board is respectively distributed in the direction vertical to the length direction of the circuit board, so the area capable of being illuminated by each LED on the width range of the PC cover is larger, and one the other hand, the equation between the covering angle of the PC cover and the illumination angle required by the light rays is realized through increasing the distance between the LED and the PC cover, so the light generated by the LEDs is completely illuminated onto the PC cover, and good illumination atmosphere is generated.

Description

Technical field [0001] The invention relates to the field of LED fluorescent lamps, and more specifically to an improved structure of an LED tube capable of solving the black areas on both sides of the LED fluorescent lamp. Background technique [0002] With the continuous development of domestic LED technology, many manufacturers are currently considering the use of domestic low-cost labor to sell their LED fluorescent lamps to overseas such as Europe. However, if they want to sell their products to Europe, they must let the products Meet the European product certification. [0003] For example, there is a requirement in European certification that the distance between the LED lamp in the LED fluorescent lamp and the outer edge of the aluminum substrate is at least 5mm; due to the oblique arrangement or the word (such as 3014, 30 length direction parallel to the circuit board length direction, and 14 width The length of the circuit board is vertical), so as to ensure that the len...
