Abstract

The utility model provides a LED lamp, which comprises a lamp shell, wherein a power cavity is arranged at the lower part of the lamp shell, and a power supply is arranged in the power cavity; the upper part of the lamp shell is provided with a light source plate; the power supply is electrically connected to the light source board and is also connected with an external power line; the lampshade presses the light source plate on the lamp shell; the power is fixed on the light source board through the connecting piece that a plurality of interval distance set up, makes power and light source board keep the certain distance. The utility model has the advantages that the power supply and the light source plate are spaced at a certain distance, so that the power supply and the light source plate both have good heat dissipation; the power is installed on the light source board, reduces wire length and the cost is reduced.

Description

LED lamp

Technical Field

The utility model relates to a lamps and lanterns, in particular to LED lamps and lanterns.

Background

In the existing LED lamp in the market, the heat dissipation problem is mostly considered, otherwise, the service life of the lamp is influenced. The LED lamp inevitably uses a power supply, and the power supply also generates heat in the using process. The lamp has two installation positions of a common power supply in the lamp, one is that the power supply is directly connected to the lower surface of the light source plate in a sealing and bonding mode to play a waterproof role, but the mode not only influences the heat dissipation of the light source plate, but also conducts the heat generated by the power supply to the light source plate, thereby influencing the service life of the lamp; the other kind is to fix the power in the bottom of lamp body with screw or joint mode, and with the contactless of light source board, consequently can not influence the heat dissipation of light source board, but this kind of structure no matter fixes the power on the lamp body through electric wire connection to the power to the light source board earlier, or fixes the power on the lamp body earlier and then the electric wire is connected light source board and power, because the convenient needs of equipment, all needs longer electric wire, leads to high in production cost.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model provides a LED lamp, the heat dissipation is good, and the cost is lower, and the simple installation is simple and convenient.

The technical scheme provided by the utility model does: an LED lamp comprises a lamp shell, wherein a power supply cavity is arranged at the lower part of the lamp shell, and a power supply is arranged in the power supply cavity; the upper part of the lamp shell is provided with a light source plate; the power supply is electrically connected to the light source board and is also connected with an external power line; the lampshade presses the light source plate on the lamp shell; the power is fixed on the light source board through the connecting piece that a plurality of interval distance set up, makes power and light source board keep the certain distance.

The utility model has the advantages that the power supply and the light source plate are spaced at a certain distance, so that the power supply and the light source plate both have good heat dissipation; the power is installed on the light source board, reduces wire length and the cost is reduced.

Detailed Description

As shown in fig. 1 to 4, an LED lamp includes a lamp housing 1, and a power supply cavity 11 is integrally formed at a lower portion of the lamp housing 1. The power supply 2 is enclosed in a power supply box which is located in the power supply cavity 11. The electric wire 21 has one end connected to the power source 2 and the other end connected to the light source board 3. The power supply 2 is also connected with an external power line 5. Two connecting pieces 22 are integrally formed on the power supply box of the power supply 2 and the power supply box, and the two connecting pieces 22 are respectively arranged on two opposite sides of the power supply 2. Of course, there may be a plurality of connecting members 22, and a certain distance is provided between each two connecting members to ensure that the air between the power source 2 and the light source plate 3 can be well circulated with the ambient air. The top end of the connecting piece 22 is bonded on the lower surface of the light source plate 3 through the adhesive, and the connecting piece 22 keeps a certain distance between the power supply 2 and the light source plate 3 to ensure that a good heat dissipation space is formed between the power supply and the light source plate. The connection of the connector 22 to the light source board 3 may also be by screws or welding. The lampshade 4 is provided with a plurality of hooks which are inserted into holes matched with the lamp shell 1, and the light source plate 3 is pressed between the lampshade 4 and the lamp shell 1.

Fig. 5 is the second embodiment of the present invention, a clamping groove 23 is formed on one end of the connecting element 22, the circuit board edge of the power supply 2 is inserted into the clamping grooves of the two symmetrically arranged connecting elements 22, and the thickness of the circuit board is slightly smaller than or equal to the width of the clamping groove 23, so as to prevent the circuit board from being separated. The other end of the connector 22 is bonded to the lower surface of the light source plate 3 by an adhesive.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the scope of knowledge possessed by those skilled in the art.

Claims
