Description

A kind of LED light

technical field

The utility model relates to a lighting device, in particular to an LED lamp.

Background technique

Existing LEDs have been widely used in various light bulbs, and the common use is to change the original filament position into an LED form, and the lamp holder with the original structure is still used, because the LED lighting has a certain directionality. , The lighting direction of the LED usually chooses the direction away from the lamp head to avoid the cover of the light by the lamp head, that is, the lamp head is on the top, the LED is lighting down or the lamp head is on the bottom, and the LED is lighting up. Especially in the lighting of public roads, it is often necessary to design the position of the lamp head to illuminate the road, and the design of the lamp holder is complicated. The use cost is high and the installation is difficult. However, if the street lamps installed on some fences are designed as a structure with the lamp head at the top and the lighting direction downward, it is easy to damage and affect the environmental landscape; the structure with the lamp head at the bottom and the lighting direction upward Often results in a lot of waste of light sources.

Contents of the invention

The technical problem to be solved by the utility model is to provide an LED lamp suitable for the position of the lamp head in the direction of illumination.

According to the LED lamp proposed by the utility model, it includes a lamp holder that can be connected to a power supply, a lamp holder holder connected to the lamp holder, a transparent shell, a heat sink, a PCB board with LEDs installed, and an LED drive power supply. It is characterized in that the transparent One end of the shell is connected to the lamp cap holder, the opposite end of the transparent shell and the lamp cap is connected to the LED mounting surface of the PCB board, the other side of the PCB board is connected to the heat sink, the lamp cap is electrically connected to the LED drive power supply, and the LED drive power supply is connected to the PCB board The LEDs are electrically connected.

The LED mounting surface of the PCB board is an outwardly protruding arc or tapered surface. In this way, the direction of the light irradiated by the LED is more scattered, and the lighting effect is better.

The side opposite to the LED mounting surface of the PCB board is fixedly connected to the heat sink, and the heat sink on which the PCB board is fixed is set as a threaded edge or a slot for fixed connection with the transparent housing. The cooling body plays the role of dissipating the heat emitted by the LED, and the cooling body and the transparent housing are fixedly connected by a threaded edge or a slot, which is stable and easy to install and disassemble, and is quite convenient to use.

A light reflector whose surface is a light reflective layer is arranged on the central axis of the lamp cap fixing seat in the inner cavity of the transparent shell. In this way, the light directly irradiated from the LED can be refracted outwards, avoiding being blocked by the lamp cap holder, and improving the lighting effect.

The surface of the reflector is arranged as an inclined plane or an oblique arc-shaped surface relative to the central axis of the lamp cap fixing seat. This allows light to be refracted evenly outward.

The surface of the reflector is a conical surface, and the bottom end of the reflector is at the position close to the fixing seat of the lamp cap. In this way, the tapered surface can be used as a reflective surface to refract the light directly irradiated by the LED more towards the ground, so as to improve the lighting effect.

The LED driving power is placed on the radiator and electrically connected to the lamp holder through the wires in the reflector. In this way, the lamp holder can be designed smaller to avoid blocking the light; the LED driving power can also be placed in the lamp holder to be electrically connected to the lamp, and to be electrically connected to the LED on the PCB through the wire in the reflector.

The PCB board and the cooling body are fixed with screws, and the PCB board and the cooling body are coated with heat dissipation material. Heat dissipation silicon or other heat conduction medium can be coated between the PCB board and the heat sink to improve the heat dissipation performance of the LED and enhance the stability of the LED operation.

In the utility model, the LED is designed at the end opposite to the lamp cap, and the light-emitting direction of the LED faces the lamp cap. In this way, when the utility model is applied to the upward position of the lamp holder, the light-emitting direction of the LED lamp of the present utility model is downward, that is, its lighting direction Facing down, it achieves the purpose of lighting, and solves the problem of wiring and light blocking when the LED is designed at the end opposite to the lamp head, and has good economic benefits.
