Background technique

LED (Light Emitting Diode, Light Emitting Diode) is a solid-state semiconductor device that can directly convert electricity into light. The heart of LED is the wafer of a semiconductor, and one end of wafer is attached on a bracket, and one end is negative pole, and the other end connects the positive pole of power supply, and whole wafer is encapsulated by epoxy resin. Semiconductor wafer is made up of two parts, and a part is P-type semiconductor, and hole occupies an leading position in it, and the other end is N-type semiconductor, and here mainly is electron. But time these two kinds of semiconductors couple together, between them, just form a "P-N junction". When electric current acts on this chip by wire time, electron will be pushed to P district, and in P district, electron is with hole recombination, then will send energy with the form of photon, the principle of LED luminescence that Here it is. And the wavelength of light determines the color of light, be determined by the material forming P-N junction.

However, the heat dissipation technology of LED lamps is still a subject that people have been studying. The heat dissipation effect of existing LED lamps is not very good, so that the service life of LED lamps is affected.

Contents of the invention

The main purpose of the utility model is to provide an LED lamp, aiming at achieving fast heat dissipation of the LED lamp with obvious effect, preventing overheating of the LED lamp bead and prolonging the service life of the LED lamp.

The utility model proposes an LED lamp, which includes a lamp cap that can be connected to an external power supply, a main body, and a radiator clamped between the main body and the lamp cap. Several V-shaped grooves are arranged on the side of the main body. An aluminum substrate connected to the heat sink is arranged in the V-shaped groove, LED lamp beads are arranged on the aluminum substrate, and a reflective cup is arranged in the V-shaped groove, and the reflective cup and the main body A gap is provided between them, and the gap leads to the outside of the LED lamp, and a light-transmitting cover is arranged on the reflector cup.

Preferably, several bumps are arranged between the reflective cup and the main body and on the reflective cup.

Preferably, the lamp cap is provided with several ventilation holes for the driving circuit to dissipate heat.

Preferably, the main body is made of metal material.

The LED lamp of the present utility model includes a lamp cap, a radiator and a main body. The aluminum substrate provided with LED lamp beads is installed on the V-shaped groove on the side of the main body. The heat generated by the LED lamp beads is gathered on the aluminum substrate, and the aluminum substrate will The heat is conducted to the main body made of metal material and the heat sink connected to the main body. Since the reflective cup and the main body are separated by a plurality of protrusions, and the said protrusions are arranged on the reflective cup, there is a ventilated gap between the reflective plate and the main body, which is convenient for the main body to dissipate heat. The radiator and the main body dissipate heat at the same time, and the heat dissipation speed is accelerated, which can prevent the LED lamp beads from overheating and prolong the service life of the LED lamp. Moreover, a number of ventilation holes are also arranged on the lamp head part, which is beneficial to drive heat dissipation and ventilation, and ensures the service life of the drive.
