Description

A LED downlight with a die-casting lamp cup

technical field

The utility model relates to the technical field of lighting fixture products, in particular to an LED downlight.

Background technique

Because LED light sources have the characteristics of high luminous efficiency, low power consumption, long service life, strong safety and reliability, and meet the requirements of energy saving and environmental protection, they are regarded as the fourth generation of new light sources. At present, LED energy saving has begun to be promoted and applied to the market, and many cities have applied LED light source lighting technology to the construction of urban road lighting environments, and have produced good results. As we all know, the main disadvantage of LED lights is that they generate a lot of heat, and because the space for installing LED light sources is small, if the heat dissipation problem of LEDs cannot be solved well, it will affect the work of LEDs, which will lead to faster lighting of LED lights. Aging and damage will reduce the service life of LED and fail to achieve the effect of energy saving. At present, heat sinks are usually used to solve the heat dissipation problem of LED lights, that is, the driver is installed on a heat sink made of aluminum alloy, and multiple independent fins are set on the heat sink. At present, the heat sinks on the market are all independent part. The disadvantage of this method is that, first, the independent radiator is large in size and needs to occupy a large space, which will increase the volume of the whole lamp; second, due to the joint between the radiator and the lamp cup, this will affect the Its heat dissipation effect; Third, the independent manufacturing of the heat sink needs to increase the larger cost.

Utility model content

Aiming at the defects of the prior art, the utility model provides an LED downlight with a die-casting lamp cup with more ideal heat dissipation effect, lower manufacturing cost and flexible control of the whole lamp volume.

In order to solve the above technical problems, the utility model adopts the following technical scheme: an LED downlight with a die-casting lamp cup, including a lamp holder, an LED light source, a driving component, a lamp cup, a PCB board and a condenser lens, and the LED light source is installed on On the PCB board, the PCB board is connected to the drive assembly, the drive assembly is installed on the lamp holder, the lamp holder is connected to the lamp cup, the PCB board is installed in the lamp cup, the condenser lens is installed on the lamp cup and the LED light source and the PCB board are closed In the lamp cup, it is characterized in that: the outer surface of the lamp cup is provided with a radiator composed of cooling fins, and the cooling fins cover the entire outer surface of the lamp cup; the cooling fins and the lamp cup are made of integral die-casting, and the two The one-body structure.

Further, the condensing lens is arranged with several mutually independent lens units, and each lens unit corresponds to an LED light bead.

Further, the heat dissipation fins are arranged longitudinally on the outer surface of the lamp cup.

Further, the heat dissipation fins are made of aluminum alloy.

The utility model integrates the independent heat sink and the lamp cup in the traditional technology by directly setting the cooling fins on the outer surface of the lamp cup, so that the integral molding can be directly adopted in the manufacture, which can greatly reduce the cost; and due to the heat dissipation The radiator and the lamp cup are integrated, so it has a more ideal heat dissipation effect; in addition, after omitting the traditional independent radiator, the volume of the whole lamp can be made smaller according to the need, so it has a wider application range.
