Combined lighting device

Abstract

The invention discloses a combined solid-state light source lighting device. The device comprises at least two solid-state light source modules and a fixed bracket, wherein each solid-state light source module comprises a substrate, a solid-state light source and a pedestal; a circuit is arranged on the substrate; the solid-state light source is arranged on the substrate; an electrode of the solid-state light source is electrically connected with the circuit on the substrate; the solid-state light source is also thermally connected with the substrate; and the substrate is thermally connected with the pedestal. In the solid-state light source lighting device, the at least two solid-state light source modules are combined by using the fixed bracket, and heat sources of all the solid-state light source modules are mutually scattered. A power source is independent of the solid-state light source modules, so that the integral lighting device can be operated at a high temperature and can be randomly expanded and combined.

Description

technical field [0001] The invention relates to a lighting device, in particular to a combinable solid-state light source lighting device. Background technique [0002] A light emitting diode (LED, Light Emitting Diode) is a semiconductor solid-state light source component that can convert current into light in a specific wavelength range. Light-emitting diodes have the advantages of high brightness, low operating voltage, low power consumption, easy matching with integrated circuits, simple driving, and long life, so they can be widely used as light sources in the field of lighting. For details, please refer to Joseph Bielecki et al. , Thermal Considerations for LED Components in an Automotive Lamp in the 23rd IEEE SEMI-THERM Symposium. [0003] Known solid-state light source lighting devices, such as Delta (Delta Electric) street lamp SLDT series and Shenzhen Bangbeier high-power LED street lamp LU2; LU4; LU6, mostly integrate many solid-state light sources and power modu...

AI Technical Summary

Problems solved by technology

Once the independent power supply is damaged, the entire lamp must be disassembled, and a whole light-emitting module needs to be replaced. Usually, the life of the power module is shorter than that of the solid-state light source component, so it is forced to be replaced due to the damage of the power module. Solid-state light source components, quite environmentally friendly and relatively high cost
