Abstract

The invention discloses a miniaturized light projection device. The miniaturized light projection device comprises a heat dissipation base, a circuit substrate, a dipped headlight module, a high beammodule, a light distribution lens and an optical structure, the circuit substrate is connected to the heat dissipation base and provided with a first installation face and a second installation face opposite to the first installation face, the dipped headlight module corresponds to the high beam module in position, and the dipped headlight module comprises a first light-emitting unit arranged on the first installation face. The high beam module comprises a second light-emitting unit arranged on the second installation face, the position of the light distribution lens corresponds to the low beam module and the high beam module, and the optical structure is arranged between the heat dissipation base and the light distribution lens. Therefore, the design requirements of miniaturization and high lighting efficiency of the device can be considered.

Description

technical field [0001] The invention relates to a light projection device, in particular to a miniaturized light projection device applied to vehicle lamp lighting. Background technique [0002] Car lights are equivalent to the eyes of power vehicles (such as locomotives or automobiles), which are very important for driving safety. Common car light sources include halogen lamps, tungsten halogen lamps and HID lamps (High Intensity Discharge Lamp). In addition, light emitting diodes (light emitting diodes, LEDs) have the advantages of small size, high luminous efficiency, low energy consumption, and environmental protection, and the light they can emit covers visible light and invisible light, and the luminous brightness can reach a considerable level. Diode (LED) to replace halogen lamps, tungsten halogen lamps or HID lamps as the light source technology is becoming more and more common. [0003] For example, Patent No. TW M539600 and Patent No. TW M536321 both disclose a ...
