Semiconductor wafer is made up of two parts, and a part is P-type semiconductor, and hole is occupied an leading position inside it, and the other end is N-type half
Conductor, in this side electronics is mainly.But when both quasiconductors are coupled together, a P-N junction is just formed between them.When
When electric current acts on this chip by wire, electronics will be pushed to P areas, in P areas electronics with hole-recombination, then
Energy will be sent in the form of photon, here it is the luminous principle of LED.And the wavelength i.e. the color of light of light, be by
Form the material decision of P-N junction.For general lighting, light source of the people with greater need for white.
Existing LED, including LED lamp bead and heat-dissipating casing, have what LED lamp bead was driven in heat-dissipating casing
Circuit board, LED lamp bead caloric value itself is less, but circuit board is the larger part of caloric value, therefore heat-dissipating casing needs
There is preferable heat sinking function.Existing heat-dissipating casing relies primarily on the fin radiating on the whole body, and radiating effect is limited.
The content of the invention
The purpose of this utility model is a kind of radiating LED lamp designed to solve the not enough of above-mentioned technology.
A kind of radiating LED lamp designed by this utility model, including LED lamp panel, drive circuit board, screw joint and dissipate
Hot shell, the LED lamp panel is provided with LED lamp bead；Screw joint is located at heat-dissipating casing top, the drive circuit board and LED
Lamp plate is electrically connected, and it is characterized in that the heat-dissipating casing is made up of upper shell and lower cover, and the upper shell and lower cover are nested company
Connect, the drive circuit board is located in the upper casing body, the LED lamp panel is located in the lower cover body, the upper shell whole body
It is provided with the first fin；The lower cover top is provided with some circle thermal columns, and the thermal column whole body is provided with the second fin.
As preferred：
The heat-dissipating casing is aluminium.
It is covered with through hole on first fin and the second fin, further to improve radiating effect.
Radiating LED lamp designed by this utility model, its beneficial effect is：It has two radiator structures, one
It is to be located at the first fin with upper shell week, another is some circle thermal columns for being located at lower cover top；First radiating
Piece is circumferentially spaced apart, and quantity is more, and surface area is big, can form good radiating effect, and its effect is directed to positioned at upper shell
Interior drive circuit board, caloric value is larger when being worked due to drive circuit board, is arranged by the specific aim of the first fin, can be with
Radiating effect is effectively improved, makes drive circuit board work more stable；Thermal column is circumferentially distributed, and thermal column is large number of, together
When due to it be stereochemical structure, the second fin is provided with all over the body, area of dissipation is bigger, and more preferably, it is on the one hand under for effects
LED lamp panel in cover body forms radiating, it is often more important that because upper shell and lower cover are nested connection, so can not only be easily
Install, and the conduction of heat can be formed between the two, once the first fin on upper shell radiates not in time, on lower cover
Thermal column can also play auxiliary heat dissipation effect so that the heat dispersion of whole heat-dissipating casing is significantly improved, LED can be extended
Service life, it is ensured that the job stability of LED.
Description of the drawings
Fig. 1 is the structural representation of the radiating LED lamp of embodiment 1；
Fig. 2 is the top view of the lower cover of embodiment 1；
Fig. 3 is the enlarged drawing in Fig. 2 at A；
In figure：LED lamp panel 1, drive circuit board 2, screw joint 3, heat-dissipating casing 4, LED lamp bead 5, upper shell 6 and, under
Cover body 7, the first fin 8, thermal column 9, the second fin 10.
Specific embodiment
The utility model will be further described to combine accompanying drawing below by embodiment.
Embodiment 1：
As shown in Figure 1, 2, 3, the radiating LED lamp described by the present embodiment, including LED lamp panel 1, drive circuit board 2, spiral shell
Mouth joint 3 and heat-dissipating casing 4, the LED lamp panel 1 is provided with LED lamp bead 5；Screw joint 3 is located at the top of heat-dissipating casing 4, described
Drive circuit board 2 and LED lamp panel 1 are electrically connected, and it is characterized in that the heat-dissipating casing 4 is made up of upper shell 6 and lower cover 7, described
