Rear LED combined lamp

Abstract

The invention relates to a rear LED combined lamp. The rear LED combined lamp is formed by assembling lamp glass (1), a lamp shell (2), a middle plate (3), an LED module (4), a self-tapping screw (5), position lamp inside glass (6) and a position lamp light baffle (7) in a sealed mode. The rear LED combined lamp is characterized in that the LED module is composed of a position lamp LED module, a braking lamp LED module, a reversing lamp LED module and a steering lamp LED module; the position lamp inside glass and the position lamp light baffle are connected through the self-tapping screw; the middle plate and the LED module are parallel and are spaced by 1-5 cm; and the thickness of the position lamp inside glass is 1.5-2.0 mm. Through the design of combination of signals lamps for steering, reversing and the like, the lamp structure can be arranged reasonably under the situation that the assembly space dimension of the lamp is limited, and the space volume of the lamp is reduced. Meanwhile, various development costs and mold manufacturing costs of the lamp are reduced, and the car lamp is attractive in appearance, capable of saving energy and high in practicability.

Description

technical field [0001] The technology of the present invention belongs to the field of automobile engineering, and in particular relates to an LED rear combination lamp. Background technique [0002] Car rear combination lights are generally composed of signal lights such as position lights, brake lights, reversing lights, and turn signals. The light sources used range from halogen bulbs to HID bulbs, and then to the increasingly popular LED light source. Traditional halogen bulbs and HID bulbs will emit a lot of heat when the bulb is lit, causing the temperature of the entire bulb to rise, and the overall temperature of the bulb is in a high state. In addition, there are special requirements for the material performance of the lamp housing, the surface spraying process and quality, and the design of the focusing space, which increases the manufacturing cost of the lamp. LED has the advantages of long service life, fast response, and strong brightness. With the development ...

LED has the advantages of long service life, fast response, and strong brightness. With the development of LED technology, in the field of automotive lighting engineering design, engineers continue to apply LED new light sources to the design of car lights, which has become the development of today's car lights. A new highlight of the current market production of LED automotive rear combination lamps is unreasonable in structure and layout, and the lamps occupy a large space, resulting in a larger daytime running light and reducing the aesthetics of its appearance. LED automotive rear combination lamps There is a problem of difficult LED heat dissipation in the lighting structure setting, which greatly reduces the service life of LED daytime running lights, and it is difficult to meet consumers' needs for safety, aesthetics, and energy saving of car lights, and the LED car rear combination lights on the market The development cost of various components of lamps and mold manufacturing costs are high, resulting in high production costs of LED automotive rear combination lamps and lamps, and it is difficult to effectively promote the development of LED automotive lighting industry
