Problems solved by technology
However, LED technology is not perfect for portable lighting appliances such as flashlights that use small bulbs (or lamp beads) to emit light.
The imperfect way is embodied in: the internal control circuit board of this kind of LED lamp bead is round as a whole, which occupies a large space; when the lamp bead emits light, the heat generated does not use a heat sink to dissipate the heat in time. Affect the service life of the lamp bead; the way the lamp head is connected to the control circuit board is generally to directly connect the two round metal wires of the anode and the cathode to the anode and cathode connectors of the control circuit board. This connection method is prone to short circuit

Embodiment Construction
[0012] Such as figure 1 , figure 2 , image 3 As shown, the present invention includes an LED lamp holder 1 , a lamp holder 2 , a heat-dissipating aluminum sheet 3 , a control circuit board 4 , a support lamp holder 5 , and a lamp base 6 . The LED lamp holder 1 also includes a positive electrode 10 and a negative electrode 11 . The heat-dissipating aluminum sheet 3 is set on the outer surface of the LED lamp holder 1 to form a whole, and the whole is placed inside the lamp holder 2, and the upper end of the LED lamp holder 1 emits light and illuminates through the lamp holder 2. The top round hole is exposed outside the lamp tube 2, and the size of the round hole matches the luminous lighting part. The heat dissipation aluminum sheet 3 is in the shape of a drum as a whole and is coated with an insulating layer on all sides. The circumference of the heat dissipation aluminum sheet 3 is cut with installation gaps 12 corresponding to the positive electrode 10 and the negative ...

Description
technical field [0001] The invention relates to an LED lamp bead. Background technique [0002] In the existing field of lighting fixtures, semiconductor lighting is a new type of solid-state cold light source, and its light source LED (light-emitting diode) has significant advantages such as high efficiency, energy saving, environmental protection, and long service life. Its power consumption is only 10%-20% of traditional lamps with the same brightness. It is regarded as another revolution in the field of lighting, and is also recognized as a new green light source by the world. [0003] With people's pursuit of quality of life, people's concept of green environmental protection is becoming stronger and stronger, especially for some daily necessities, which require health and environmental protection. Since ordinary incandescent lighting devices generate large amounts of heat and produce strong radiation, they tend to be gradually replaced by other types of lighting devic...
