Description

Technical Field

[0001] The utility model relates to the field of lamps, and particularly relates to a non-polar light-emitting module and a lamp. Background Art

[0002] LED lamps are the most widely used lighting appliances in people's daily life. According to their power supply types, they can be divided into DC lamps and AC lamps. The power supply of DC lamps is direct current, and the power supply of AC lamps is alternating current. However, in existing AC lamps, since the LED lamp beads have polarity, the alternating current is finally rectified into direct current and then provided to the LED lamp beads. This structure of LED lamps requires additional rectifying devices, undoubtedly increasing the production cost and reducing the market competitiveness. Therefore, there is an urgent need for a non-polar light-emitting module and a lamp to solve the above problems. Summary of the Utility Model

Description of the Drawings

[0013] The above and / or additional aspects and advantages of the present utility model will become apparent and be readily understood from the following description of the embodiments in conjunction with the accompanying drawings, where:

[0014] Figure 1 It is a schematic structural diagram of a lamp. Detailed Embodiments

[0015] This part will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the drawings. The function of the drawings is to supplement the description in the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it cannot be understood as a limitation on the protection scope of the present utility model.

[0016] In the description of the present utility model, the meaning of "a plurality" is more than two. Understandings such as "greater than", "less than", and "exceeding" do not include the present number, and understandings such as "above", "below", and "within" include the present number. If there is a description of "first" and "second", it is only for the purpose of distinguishing technical features and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or implicitly indicating the sequence relationship of the indicated technical features.

[0017] In the description of the present utility model, it should be understood that for the orientation description, such as the orientation or position relationship indicated by "upper", "lower", "front", "rear", "left", "right", etc., is based on the orientation or position relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model.

[0018] In the present utility model, unless otherwise clearly defined, terms such as "arranged", "installed", and "connected" should be understood in a broad sense. For example, they can be directly connected, or indirectly connected through an intermediate medium; they can be fixedly connected, or detachably connected, or integrally formed; they can be mechanically connected; they can be the communication inside two components or the interaction relationship between two components. Those skilled in the art can reasonably determine the specific meanings of the above terms in the present utility model in combination with the specific content of the technical solution.

[0019] Referring to Figure 1 , a non-polar light-emitting module includes a substrate 10, a first power line 20, a second power line 30, and a plurality of light source modules 40;

[0020] The first power line 20 is arranged on the substrate 10 and is connected to one end of an AC power supply;

[0021] The second power line 30 is arranged on the substrate 10 and is connected to the other end of the AC power supply;

[0022] The light source module 40 includes at least one first light source 41 and at least one second light source 42. The first light source 41 and the second light source 42 have a positive electrode and a negative electrode. The positive electrode of the first light source 41 and the negative electrode of the second light source 42 are connected to the first power line 20, and the negative electrode of the first light source 41 and the positive electrode of the second light source 42 are connected to the second power line 30;

[0023] The first light source 41 can be lit during the positive half cycle of the AC power supply, and the second light source 42 can be lit during the negative half cycle of the AC power supply.

[0024] In the present utility model, when the AC power supply is in the positive half cycle, the first power line 20 serves as the positive electrode and the second power line 30 serves as the negative electrode. Then, the voltage is applied to the first light source 41, causing the first light source 41 to conduct and emit light. Since the second light source 42 is reversely connected, it will not conduct. When the AC power supply is in the negative half cycle, the first power line 20 serves as the negative electrode and the second power line 30 serves as the positive electrode. Then, the voltage is applied to the second light source 42, causing the second light source 42 to conduct and emit light. Since the first light source 41 is reversely connected, it will not conduct. Further, the positive and negative electrodes of the AC power supply alternate, causing the first light source 41 and the second light source 42 to alternately light up. Since the frequency of the positive and negative electrode switching is relatively high, the process of the first light source 41 and the second light source 42 alternately lighting up cannot be detected by the naked eye, thus creating an "always-on" light effect. Using one first light source 41 and one second light source 42 as the minimum light source module 40, and integrating multiple light source modules 40 on one lamp, the lamp can be directly applied to the AC power supply. The advantages of the present utility model are as follows: Through the above structure, AC power can be directly used to supply power to the light source module, without the need for additional rectifying devices, which can reduce production costs and has very good practicability.

[0025] As a first embodiment of the first light source 41 and the second light source 42, the first light source 41 and the second light source 42 are arranged as flip-chip COB light sources.

[0026] As a second embodiment of the first light source 41 and the second light source 42, the first light source 41 and the second light source 42 are arranged as LED lamp beads.

[0027] A lighting fixture includes the electrodeless light-emitting module described above.

[0028] Of course, the present invention is not limited to the above embodiments. Those skilled in the art can make equivalent deformations or substitutions without departing from the spirit of the present invention, and these equivalent deformations and substitutions are all included in the scope defined by the claims of this application.
