TW202020370A - Lamp device capable of relatively increasing the light emitting area of the main lamp tube - Google Patents

Abstract

This invention relates to a lamp device including a main lamp tube and a light emitting circuit board disposed inside the main lamp tube. One side of the light emitting circuit board is provided with a plurality of LED light sources, and the first end of the main lamp tube is sleeved with a first clamping end cover which is a light transmitting body. Since the first clamping end cover is the light transmitting body, rays of the plurality of LED light sources of the light emitting circuit board in the main lamp tube may penetrate through the first clamping end cover, and thus the light emitting area of the main lamp tube may be relatively increased.

Description

Lamps

The invention relates to a light-emitting device, especially a lamp.

Lamps are widely used in lighting, warning, beauty, and even advertising. In addition to fluorescent lamps, for long-term use of lamps (such as but not limited to advertising lamps), in order to save power and energy, many LED luminous bodies have been used as light-emitting elements. The lamp includes a main lamp tube, a light-emitting circuit board is arranged inside the main lamp tube, a plurality of LED luminous bodies are arranged on one side of the light-emitting circuit board, and a first clamp is sleeved on the first end of the main lamp tube Holding the end cap, the first clamped end cap is usually used to allow the surrounding fixture to clamp the lamp, but in order to avoid directly clamping the main lamp (usually made of glass), the first clamped end cap The holding end cover is usually made of plastic so as to withstand the wear of the holding tool. However, since the first clamped end cover is also opaque, the plurality of LED luminous bodies of the light-emitting circuit board in the main lamp tube cannot penetrate the first clamped end cover, so that the lamp emits light The area is limited.

In view of the problems of the prior art, the inventor believes that there should be an improved structure, for which a lamp is designed, including a main lamp tube, a light-emitting circuit board is arranged inside the main lamp tube, and a plurality of light-emitting circuit boards are provided on one side An LED luminous body, and a first clamped end cover is sleeved on the first end of the main lamp tube, and the first clamped end cover is a light-transmitting body. Since the first clamped end cover is a light-transmitting body, a plurality of LED luminous bodies of the light-emitting circuit board in the main lamp tube can penetrate the first clamped end cover, thus making the main lamp of the lamp The light emitting area of the tube can be relatively enlarged.

The following describes the structure, features, and embodiments of the present invention through the cooperation of the drawings, so that your reviewer can have a better understanding of the present invention. Please refer to the first figure and the second figure, the present invention relates to a lamp, including a main lamp (1), the main lamp (1) is provided with a light-emitting circuit board (11), the light-emitting circuit board ( 11) A plurality of LED illuminants (111) are provided on one side, and a first clamped end cap (2) is sleeved on the first end of the main lamp tube (1), and the first clamped end cap (2) ) Is a light-transmitting body, and the light transmittance of the first clamped end cover (2) is not less than 75% of the light transmittance of the main lamp tube (1). Please refer to the third figure, since the first clamped end cap (2) of the present invention is a light-transmitting body, the plural LED light-emitting bodies of the light-emitting circuit board (11) in the main lamp tube (1) ( 111), the light can penetrate the first clamped end cover (2), so that the light emitting area of the main lamp tube (1) of the lamp can be relatively enlarged. To further make the main lamp tube (1) of the lamp have a larger light emitting area, the present invention sets a second clamped end cap on the second end opposite to the first end of the main lamp tube (1) ( 3) The second clamped end cover (3) is also a light-transmitting body. The light transmittance of the second clamped end cover (3) is not less than 75% of the light transmittance of the main lamp tube (1). The light-emitting circuit board (11) extends a wire, one end of the wire is electrically connected to the light-emitting circuit board (11), the other end penetrates the main lamp tube (1) and the first clamped end cover (2) and Bare the first clamped end cap (2) into a line segment, and the line segment respectively forms a first segment (13) and a second segment (14), the outer end of the first segment (13) includes a The first connecting piece (13A), the outer end of the second section (14) includes a second connecting piece (14A), and the second section (14) is provided with a starter (15). In this way, when the starter (15) fails, the user only needs to unplug the second connecting piece (14A) of the second section (14) relative to the first connecting piece (13A), The starter (15) is sent for repair or replacement, and the replacement or repair is limited to a small part without having to be replaced or repaired as a whole, which is more cost-effective. According to the invention, the light-emitting circuit board (11) extends the wire, one end of the wire is electrically connected to the light-emitting circuit board (11), and the other end penetrates the main lamp tube (1) and the first The clamped end cap (2) exposes the first clamped end cap (2). Since the "radial" penetrates the main lamp tube (1) and the first clamped end cap (2), axial penetration can be avoided and the outer end of the first clamped end cap (2) can be avoided When naked, the overall axial length is too long to be interfered by surrounding clamping pieces or other objects. In summary, the present invention is indeed in line with industrial utilization, and it has not been seen in publications or public use prior to the application, nor is it known to the public, and it is non-obvious and easy to understand, and meets the requirements of patentability. . However, what has been described above is a preferred embodiment in the invention industry, and any equal changes made according to the patent application scope of the present invention are within the scope of the subject matter of this case.
