Problems solved by technology

[0002] In the prior art, LED (Light Emitting Diode) is a new light source with low power consumption and high light energy conversion rate. With the development of material technology, it is more and more widely used in various lighting technologies, and it is also becoming a common life in people's lives. resources, but because the power of a single LED light source is relatively small, in practical applications, multiple LED light sources are used to form larger lighting fixtures, which cannot be applied to smaller volume lighting or lighting fixtures. limitations

Embodiment 1

[0016] Embodiment 1: One string of lights.

[0017] image 3 It is DC12V, schematic diagram of 6 lights, one light in a string.

[0018] The LED lamp is a patch lamp with a high power of 1w, and the resistor can be 2512 with a high power of 2w. Among them, the LED is 1w, 350mA, the chip resistor 2512 is packaged as 6.4*3.2mm, and the resistance value can be R=14R;

[0019] DC=13.5V, the current of each string can be guaranteed to be about 350mA, that is, the LEDs emit light normally.

[0020] The total current is: 0.35*6=2.1A

[0021] The total power is: 2.1*13.5=28.35w

Embodiment 2

[0022] Embodiment two: two lamps in one string.

[0023] Figure 4 It is DC12V, schematic diagram of 12 lights, two lights in a string.

[0024] The LED lamp is a patch lamp with a high power of 1w, and the resistor can be 2512 with a high power of 2w. Among them, the LED is 1w, 350mA, the chip resistor 2512 is packaged as 6.4*3.2mm, and the resistance value can be R=9R.

[0025] DC=13.5V, the current of each string can be guaranteed to be about 350mA, that is, the LEDs emit light normally.

[0026] The total current is: 0.35*6=2.1A

[0027] The total power is: 2.1*13.5=28.35w

Embodiment 3

[0028] Embodiment 3: three lamps in one string.

[0029] Figure 5 It is DC12V, schematic diagram of 6 lights, and a string of three lights.

[0030] The LED lamp is a high-power 1w patch lamp, and the resistor can use a high-power 1w 2512. Among them, the LED is 1w, 350mA, the chip resistor 2512 is packaged as 6.4*3.2mm, and the resistance value can be R=3.9R.

[0031] DC=13.5V, the current of each string can be guaranteed to be about 350mA, that is, the LEDs emit light normally.

[0032] The total current is: 0.35*2=0.7A

[0033] The total power is: 0.7*13.5=9.45w

Abstract

The invention provides a novel high-power LED lamp bulb which is combined together by a plug composed of high-conductivity terminals and a plastic body and a glass shade which mainly adopts an LED as the light-emitting unit, takes the thermal design of a base plate and a circuit board into consideration and improves the luminous efficiency. The heat-dissipating base plate is connected with the circuit board by adhesive paste, and a conventional LED group or a novel LED group is arranged thereon. The glass shade with high refractive index is arranged outside the base plate. One end of the base plate is connected with the plug via the circuit of the circuit board, and is further connected with an external power source via the plug. The novel high-power LED lamp bulb adopts the reflecting mirror in the original lamp to conduct the primary reflection or the multiple reflections without changing the load-bearing design of the original lamp, and realizes excellent performances, such as low energy consumption, high brightness and safety, without changing illumination requirements for various lighting fittings. The novel high-power LED lamp bulb is widely applied in vehicle industry, mining industry, research and rescue, street illumination, playground illumination, commercial illumination and general indoor illumination.
