Problems solved by technology

However, the disadvantage of this solution is that since the sensitive E-cap is located close to the central area of ​​the light engine, and since the E-cap uses electrical connecting wires for electrical connection, this area is difficult to be covered by the potting material
In addition, the driver housing in the prior art is made of PBT, and most of the electrical connection schemes use electrical connection wires to contact the pads on the circuit board of the light engine and the driver circuit board, and the existence of wire holes will cause perfusion Leakage of thermal paste

Abstract

The invention relates to a driver casing (10). The driver casing (10) is characterized by comprising a first part (1) and a second part (2); the first part (1) is made of electrical insulating material, and the second part (2) is made of conducting material; and the first part (1) and the second part (2) are formed integrally, and the second part (2) extends out of the first part (1) and serves as the electrical connecting part of the driver casing (10). The invention also relates to a luminous device and a lamp. According to the luminous device and the lamp disclosed by the invention, the manufacturing technique is simple, the cost is low, and the heat dissipation capability is remarkably improved.

Description

technical field [0001] The invention relates to a driver housing, a light emitting device and a lamp with the light emitting device. Background technique [0002] Light-emitting devices usually have relatively large heat dissipation requirements. This is because both the light engine and the driver are heat sources that generate relatively large amounts of heat. Therefore, effective heat dissipation is required to ensure the normal operation of the light-emitting device. Especially for LED light-emitting devices, the above requirements are more urgent. [0003] In light-emitting devices, some key electronic components such as the E-cap of the driver cannot withstand high temperatures and cannot still have a high service life at high temperatures, especially in the case of natural convection, it is difficult to pass through the driver housing. The heat is dissipated due to the poor thermal conductivity of the drive housing material. [0004] There are several solutions as fo...
