Description

  The present invention relates to a lamp, in particular, a base having at least one convex portion, a main body comprising a light collecting cover and a coupling portion, at least one light emitting diode, a circuit board having at least one opening, and a lamp head. By the combined design, the convex portion of the main body base and the opening of the circuit board are nest-connected to each other, and the main body is made of a heat conducting material, thereby improving the light collection and heat dissipation efficiency, reducing the manufacturing cost and assembling process. The present invention relates to a lamp that can be applied to space lighting or similar structures in a company, a house, an exhibition hall, or a public area.

Currently, the application of light-emitting diodes (LEDs) is expanding.
For this reason, the input power of the light emitting diode must also be improved. However, if the light emitting diode continues to emit light, heat is stored.
This heat generation phenomenon reduces the light emission efficiency and accelerates the temperature rise of the light emitting diode itself.
A conventional light emitting diode on a general device dissipates heat only by a circuit board coupled to the light emitting diode, but heat generated when the light emitting diode emits light is difficult to dissipate. Therefore, the light emitting diode is easily overheated and damaged.
In addition, since the light emitting diode is provided on the circuit board, the heat accumulated in the light emitting diode burns out the circuit board. In particular, lighting equipment using a high-intensity or ultra-high-intensity light emitting diode has problems such as material deterioration due to high heat or a reduction in life.

A conventional light emitting diode lamp includes a condenser lens, at least one light emitting diode, a heat conducting layer, a metal substrate, a case, a heat sink, and a lamp head.
The case has a concave cup shape, and a base is provided in the recess in the center of the case. A through hole is provided on the base, and an accommodation space is provided below the base. A light reflection layer is provided on the inner wall of the case above the base. A condensing lens is provided above the case. The light emitting diode is electrically connected to the metal substrate. Circuit wiring is disposed on the metal substrate, and the light emitting diode is coupled to the base of the case.
The heat dissipator is disposed outside the case or below the base of the case.
The lamp head is disposed below the base of the case, and the lamp head and the circuit board are electrically connected.

When the above-described light emitting diode dissipates heat, heat must first be conducted to the metal substrate below the light emitting diode, and further to the heat spreader outside the case or below the base of the case through the metal substrate and the case.
Since there are too many conduction mediations for transferring heat, heat conduction is shielded or relaxed, and the heat dissipation effect and efficiency are greatly reduced.
In addition, the conventional light-emitting diode lamp cannot achieve the light-collecting effect of the light-emitting element unless a condensing lens is mounted above the light-emitting diode and a light reflecting layer is mounted on the inner wall of the lamp cup. In addition, there are problems such as complicated assembly and high manufacturing costs.

  The present invention has been made in view of the inconvenience in using the conventional lamp described above.

The object is to provide a lamp with improved practicality.

  Another object of the present invention is that the light collecting cover of the main body is made of a metal heat conductive material, can reflect the light emitted from the light emitting diode light source, and further guides and marches the light to make it easier to collect the light source. Since a heat dissipating fin is further provided outside the light cover, it is an object of the present invention to provide a lamp that combines light collecting and heat dissipating effects and improves the overall practicality.

  Another object of the present invention is that the lamp head can be changed to a standard type such as MR-16, E27, etc. by designing the coupling part of the main body and the coupling part of the lamp head to be active coupling with each other. Is to provide a lamp that is wider and has improved overall utility.
