Full plastic ring LED lamp

技术领域Technical field

The utility model relates to the technical field of LED lamp tubes, in particular to a full plastic ring LED lamp structure.

背景技术Background technique

In the prior art, the ring lamp generally consists of a circular fluorescent tube, a driving circuit board, a copper pin and a lamp cap. The driving circuit board is installed inside the lamp cap, the copper pin and the fluorescent lamp tube are mounted on the lamp cap, and the wick of the fluorescent lamp tube passes. The driver board is electrically connected to the copper pin. In use, the copper needle supplies power to the fluorescent tube through the driving circuit board, so that the fluorescent tube emits light to realize illumination.

The defects of the traditional ring lamp are: the fluorescent tube has low luminous efficiency, generates high heat, consumes a large amount of energy, and the heat generated by the illumination makes the whole lamp temperature high and the safety is poor. In view of this, the inventors have specially developed a full-plastic ring LED lamp, and the present invention is produced.

实用新型内容Utility model content

The purpose of the utility model provides a full plastic ring LED lamp to improve product safety and energy saving effect.

In order to achieve the above object, the solution of the present invention is:

A plastic ring LED lamp consisting of a ring-shaped plastic glass tube, an LED chip, a mpcb aluminum substrate (metal-based printed circuit board) and a copper needle, and the annular plastic glass tube is composed of a circular upper half shell and a circle The annular lower half shell is formed by ultrasonic welding, the mpcb aluminum substrate is fixed in the annular plastic glass tube, the LED chip is mounted on the mpcb aluminum substrate and electrically connected, the copper needle is inserted in the annular plastic glass tube, and the copper needle is inserted. The inner end is also electrically connected to the mpcpc aluminum substrate.

The annular plastic glass tube is made of polycarbonate (Polycarbonate referred to as PC) material.

Corresponding upper and lower steps are formed at the openings of the annular upper half shell and the annular lower half shell, and corresponding upper and lower steps are formed, and the upper step and the lower step are combined to form a fixed for the mpcb aluminum substrate. Insert slot.

A reinforcing rib is formed in the annular plastic glass tube.

After adopting the above solution, the utility model replaces the annular fluorescent tube with the annular plastic glass tube with the LED chip and the mpcb aluminum substrate, and the LED chip generates low heat and consumes less energy when compared with the prior art. Energy-saving, annular plastic glass tube as a plastic outer casing, can prevent leakage and heat, so that the whole lamp temperature is low and safety is high.

The utility model can directly replace the traditional ring lamp, and the size and the shape can follow the specifications of the traditional energy-saving lamp, and the circuit of the electronic and the inductor rectifier adapted to the traditional ring energy-saving lamp tube is used.

The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

具体实施方式detailed description

As shown in FIG. 1 to FIG. 3, the utility model discloses a full plastic ring LED lamp, which comprises an annular plastic glass tube, an LED chip 2, an mcpcb aluminum substrate 3 (metal-based printed circuit board) and a copper needle 4 composition.

The annular plastic glass tube is formed by ultrasonic welding from the annular upper half shell 5 and the annular lower half shell 1. The annular plastic glass tube can be made of polycarbonate material.

The mcpcb aluminum substrate 3 is fixed in an annular plastic glass tube, and the LED chip 2 is mounted on the mpcb aluminum substrate 3 and electrically connected.

The copper needle 4 is inserted into the annular plastic glass tube, and the inner end of the copper needle 4 is also electrically connected to the mpcpc aluminum substrate 3.

In order to have a firm structure, reinforcing ribs 51 are formed in the annular plastic glass tube. In order to facilitate the installation and positioning, the upper portion of the annular upper half shell 5 and the annular lower half shell 1 form a corresponding ultrasonic line 52 and an ultrasonic wave groove 54, and the annular upper half shell 5 and the annular lower half shell 1 are The ultrasonic wire 52 and the ultrasonic wave groove 54 are engaged and engaged, and then firmly joined by ultrasonic welding. A corresponding upper step 53 and a lower step 12 are formed at the openings of the annular upper half shell 5 and the annular lower half shell 1, and the annular upper half shell 5 and the annular lower half shell 1 are welded together. The upper step 53 and the lower step 12 are combined to form a recess for fixing the mpccup aluminum substrate 3.

When the utility model is used, the copper pin 4 is turned on, and then the LED chip 2 is powered by the mpcpc aluminum substrate 3, so that the LED chip 2 emits light, and the light is diffused through the annular plastic glass tube to realize illumination. When the LED chip 2 emits light, the heat is low, the energy consumption is small, and the energy is saved. The annular plastic glass tube is used as a plastic outer casing to prevent leakage and heat generation, so that the whole lamp has low temperature and high safety.
