Problems solved by technology

In order to replace the above-mentioned high-power gas discharge lamps, even if LEDs are used, they must achieve higher power such as 40-160W or more to achieve the same illuminance requirements. For LEDs, the power is super-high power, and the radiator often requires greater power. For sodium lamps with screw caps such as E40, they cannot be directly replaced, which limits the application of LEDs in such occasions
There is currently no super-power LED bulb that can replace gas discharge lamps

Embodiment 1

[0029] like Figure 1 ~ Figure 3 As shown, the ultra-high-power LED bulb of this embodiment that replaces the gas discharge lamp can be used as a high bay lamp, and its power can reach 160W, which can directly replace the existing 400W sodium lamp; this embodiment includes a radiator 1, a cooling fan 2, a drive Circuit board assembly 3, top cover 4, lamp holder connector 5, LED light source assembly 6, light-transmitting protective cover 7, light distribution element 8, lamp holder 10, the LED light source assembly 6 includes several LED chips and LED heat dissipation substrates, the The radiator 1 includes a bottom plate 11, the bottom surface of the bottom plate 11 is a plane, the bottom plate 11 is circular, and its diameter is 10-25 cm. Of course, the bottom plate 11 can also be rectangular (including square), and the bottom plate 11 The area is 75~500cm 2, can meet the requirements of heat dissipation, the top surface of the bottom plate 11 is provided with a heat dissip...

Embodiment 2

[0031] like Figure 4 ~ Figure 6 As shown, the difference between the ultra-high-power LED light bulb replacing the gas discharge lamp of this embodiment and the first embodiment is that this embodiment also includes a power box upper cover 31 and a power box lower cover 32, and the power box upper cover 31 is connected to the power box. The lower cover 32 of the power supply box is located in the cavity area 40 and is sealed and connected to cover the driving circuit board assembly 3, so as to improve the electrical isolation performance of the driving circuit board assembly 3 and enable It is dustproof and waterproof; the bottom of the top cover 4 covers the entire side of the radiator 1, and the bottom of the top cover 4 is provided with several ventilation holes 41, and the opening ratio of the ventilation holes 41 is The surface porosity of the ultra-high-power LED light bulb is controlled to be less than 15%, so as to meet the requirements of safety regulations on the su...

Embodiment 3

[0034] like Figure 7 , Figure 8 As shown, the difference between the ultra-high-power LED light bulb replacing the gas discharge lamp of the present embodiment and the first embodiment is that the heat dissipation fan is not included in the present embodiment, that is, the radiator 1 is used for passive heat dissipation, so the heat dissipation effect is not as good as that of the embodiment. Example 1, but its power can reach 40W ~ 60W, it can directly replace the existing 80W sodium lamp, and it can be used in occasions with lower requirements.

[0035] The remaining features of this embodiment are the same as those of Embodiment 1.

Abstract

The invention discloses an ultrahigh-power LED bulb replacing a gas discharge lamp, which comprises a radiator (1), a driving circuit board component (3), a top cover (4), a lamp holder connector (5), an LED light source component (6), a light-transmission protective cover (7) and an E40 lamp holder (10). The top cover (4) is fixedly connected with the radiator (1), a cavity area (40) is formed above the radiator (1), the driving circuit board component (3) is positioned in the cavity area (40), the top cover (4) is fixedly connected with the radiator (1), the lamp holder connector (5) is fixedly connected with the lamp holder (10) through a threaded connecting portion (51) and fixedly connected with the top cover (4) through a screw, the lamp holder connector (5) is integrally conical and gradually enlarged from the lamp holder (10) to the radiator (1) after being fixedly connected with the top cover (4), the side wall of the lamp holder connector (5) is provided with a vent hole (52) so that the cavity area (40) is communicated with the outside, and the light-transmission protective cover (7) is fixedly connected with the radiator (1). The ultrahigh-power LED bulb can be applied to the field of LED lamps.

Description

technical field [0001] The invention relates to an LED lamp, in particular to an ultra-high-power LED light bulb replacing a gas discharge lamp. Background technique [0002] A gas discharge lamp is a lamp that emits light from the mixed discharge of gas and metal vapor, and is an electric light source that converts electrical energy into light through gas discharge. High pressure mercury lamps, sodium lamps and metal halide lamps are the most widely used gas discharge lamps for lighting. Sodium lamp is an electric light source that uses sodium vapor discharge to generate visible light. It is a high-intensity gas discharge bulb. It is mainly used in roads, airports, docks, ports, stations, squares, and industrial and mining lighting without color rendering requirements. In the field of lighting, sodium lamps are still the mainstream products in such lighting places. However, the power of sodium lamps is generally high, generally up to several hundred watts, so the energy s...
