Description

A light-emitting diode cup lamp

The utility model relates to a lamp, in particular to a light-emitting diode cup lamp.

In the past, there were many kinds of artificial light sources. Common light sources include: incandescent bulbs, gas discharge tubes, and fluorescent lamps. Among them, fluorescent lamps have the longest service life and save power most; however, researchers are actively developing and improving them. It is expected to develop a lamp with high luminous efficiency to meet the luminosity required in some areas. Therefore, the power circuit is often connected with a variable resistor to control the brightness of the lamp. However, it often requires multiple adjustments and viewing. Make the user feel troublesome, and will change the bulb that burns out from time to time.

The purpose of the utility model is to provide a light-emitting diode cup lamp with low power consumption, high brightness and power saving.

In order to achieve the above purpose, the utility model adopts the following design scheme: a light-emitting diode cup lamp mainly includes a light cup, a circuit board placed in the light cup and at least one light-emitting diode arranged on the circuit board; the circuit There are two resistors, two zener diodes, a fuse and a rectifier bridge on the board. A resistor and two AC power lines with different polarities are connected in parallel to the power input terminals of the rectifier bridge, and between the resistor and the AC power line A fuse and another resistor are connected in series, and the power output end of the rectifier bridge is connected in parallel with two opposite Zener diodes and at least one light-emitting diode; There are two plug-in terminals, which are integrally formed; two power lines extending from the circuit board are connected to the two plug-in terminals of the lamp cup;

The lamp cup is a closed lampshade;

The bottom of the lamp cup is a spiral bulb head with a contact portion.

Because the utility model adopts light-emitting diodes with low power consumption, high brightness and power saving as the luminous body, it only needs low wattage to produce higher brightness; 20 times longer lifespan. Solder several light-emitting diodes directly on the circuit board, and then pull out the two power lines on the circuit board to connect them to the two plug terminals on the lamp cup, and then use the integral molding method to fix the circuit board on the Inside the light cup.

Further description below in conjunction with accompanying drawings.

Fig. 2 is a perspective view of another light-emitting diode cup lamp of the present invention.

Fig. 3 is a preferred circuit diagram of the utility model.

As shown in Fig. 1, the utility model provides a light-emitting diode cup lamp, which includes a lamp cup 10, a circuit board 20 and at least one light-emitting diode 30, wherein the lamp cup 10 is a lampshade capable of concentrating light, and the lamp cup The bottom of 10 is provided with two plug-in terminals 11; the circuit board 20 is a circuit wiring board that can be placed inside the lamp cup 10, and the circuit board 20 is provided with a rectification and step-down circuit, and on the circuit board 20 Two power lines 21 are extended to connect with the two plug terminals 11 of the lamp cup 10; the light emitting diode 30 is a luminous body that can be arranged on the circuit board 20, and after the light emitting diode 30 is powered on, it can produce light of the same color or different colors .

After the aforementioned light-emitting diodes 30 are welded on the circuit board 20, the two power lines 21 on the circuit board 20 can be welded to the two plug-in terminals 11 on the lamp cup 10, and then the circuit board 20 can be fixed by integral molding. Wrapped in the lamp cup 10, and let the two plug-in terminals 11 be directly connected to the lamp holder or power supply (not shown in the figure); The guide, so that the light source is projected into the distance.

Please refer to Figure 2 again, which is a perspective view of another light-emitting diode cup lamp of the present invention. Compared with the above figure, the only difference is that the original two plug-in terminals 11 at the bottom of the lamp cup 10 are changed to screw-type contact parts. The bulb head 11A is the same as a general bulb; in addition, the lamp cup 10 can be made into a closed spherical lampshade (not shown in the figure) by blowing and vacuuming, which is similar to a general bulb.

FIG. 3 is a preferred circuit diagram of the circuit board 20 of the present invention. As shown in the figure, the circuit board 20 is provided with two resistors 22 , 23 , two Zener diodes 24 , a fuse 25 , a rectifier bridge 26 and a light emitting diode 30 . The power input terminal of this rectifier bridge 26 is connected in parallel with a resistor 23 and two AC power lines 21 with different polarities; and a fuse 25 and another resistor 22 are connected in series between the resistor 23 and the AC power line 21; Two Zener diodes 24 and at least one light emitting diode 30 are connected in parallel in series. After the two power lines are energized, the alternating current is rectified by the rectifier bridge 26 to generate direct current to provide power for all the light-emitting diodes 30, so that the light-emitting diodes 30 produce light sources; The current is turned on to protect the light-emitting diode 30; the resistor 22 can adjust and reduce the voltage; the other resistor 23 can protect the rectifier bridge 26 from being burned.
