Embodiment 1

[0022] like Figure 1-5 As shown, the LED bulb lamp provided in this embodiment includes a lampshade 6, an LED lamp panel assembly 5, an insulating base 3, a radiator 4, a power supply assembly 2 and a lamp holder 1, and the insulating base 3 includes a The cylindrical housing chamber 3-2 and the bottom of the component 2 are connected to the outer surface of the cylindrical housing chamber 3-2, and are located on the outer wall 3-1 of the cylindrical housing chamber 3-2. There is an air inlet 3-3 at the junction of the cylindrical housing chamber 3-2, the power supply assembly 2 is located in the cylindrical housing chamber 3-2, and the lamp holder 1 is socketed at the port 3-4 of the cylindrical housing chamber 3-2. Above, the radiator 4 includes a middle plate 4-1 and a heat dissipation rib 4-2 with a gap ring arranged on one side of the middle plate 4-1, and the outer edge 4-4 of the heat dissipation rib 4-2 forms a step On the surface 4-5, the heat dissipation rib 4-2 is...

Embodiment 2

[0025] The general structure of the LED bulb lamp provided in this embodiment is consistent with that of Embodiment 1, but in order to improve the illumination angle of the LED bulb lamp, it can realize wide-angle lighting similar to that of an incandescent lamp, such as Figure 7 and Figure 8 As shown, the LED light board assembly 5 includes a multi-lobed aluminum substrate 5-1 and a double-sided LED light bar 5-2 connected to each petal of the aluminum substrate 5-1. The above-mentioned aluminum substrate 5- 1 is fixed on one side of the intermediate disc 4-1.

Embodiment 3

[0027] The general structure of the LED bulb lamp provided in this embodiment is consistent with that of Embodiment 2, but in order to reduce the influence of the radiator 4 on the illumination of the LED lamp panel assembly 5, and further improve the illumination effect of the LED bulb lamp, as shown in Figure 9 and Figure 10 As shown, an LED lamp panel installation platform 4-3 is provided on one side of the intermediate plate 4-1, and the aluminum substrate 5-1 of the LED lamp panel assembly 5 is fixed on the above-mentioned LED lamp panel installation platform 4-3. 3 on.

Abstract

The invention discloses an LED bulb lamp for indoor and outdoor illumination. The LED bulb lamp comprises an LED lamp plate assembly, an insulating base and a radiator, wherein the insulating base comprises a barrel-shaped accommodating cavity for installing a power supply assembly and the outer wall with the bottom connected with the outer surface of the barrel-shaped accommodating cavity and located on the periphery of the barrel-shaped accommodating cavity. An air inlet is arranged at the connecting position of the outer wall and the barrel-shaped accommodating cavity. The radiator comprises a middle disc and a heat-radiating rib plate annularly arranged on one side of the middle disc in a gap mode, wherein the a step face is formed by the outer edge of the heat-radiating rib plate, the heat-radiating rib plate is inserted between the barrel-shaped accommodating cavity and the outer wall, and the step face of the outer edge of the heat-radiating rib plate is connected onto the opening edge of the outer wall in a blocking mode. The technical problem of high usage safety performance of the LED bulb lamp is solved, and the usage safety performance of the LED bulb lamp is directly improved on the premise that the heat-radiating effect is ensured.

Description

technical field [0001] The invention relates to an LED bulb lamp for indoor and outdoor lighting. Background technique [0002] As a new energy-saving lighting source in the 21st century, LED lights have the characteristics of high luminous efficiency, long life, low radiation, low voltage, small size, fast start-up speed, safety, environmental protection, shock resistance and pressure resistance, and easy control. used by people. There are many types of LED lamps, including LED bulb lamps, LED tube lamps, LED solar lamps, etc., among which LED bulb lamps are the most widely used. [0003] The light-emitting part of the LED bulb lamp is an LED light board composed of multiple LED light-emitting diodes. Since each LED light-emitting diode will generate heat when it is working, the above-mentioned LED light board that combines multiple LED light-emitting diodes will Very large heat is generated, and if the heat is not discharged in time, it will have a serious impact on the ...
