Description

Headlight structure

The invention relates to the technical field of the structure of a lamp, in particular to a lamp structure capable of adjusting the position of the LED so that it can project a light of good light shape and illumination.

The conventional lamp structure, as shown in Taiwan Patent No. M425788, mainly locks a light bulb onto a light bulb seat, and then fixes the light bulb seat in a rotating joint to fix it to a base. The hole is positioned such that the bulb is positioned in the reflector inside the base. Since the bulb is a tungsten bulb, the light is radiated from the periphery, so that the bulb's light can be projected forward through the reflection of the reflective surface on the inside of the reflector and the refraction of the lens on the front end of the base. And form a good light shape and illuminance.

However, because tungsten filament bulbs have the disadvantages of high power consumption, short life, and easy heat generation, in recent years, the light sources of various lamps have a tendency to replace tungsten filament bulbs with LEDs with low power consumption, long life and low heat generation. . Whereas the front end of the conventional bulb holder is provided with a projection extending to the inside of the reflector, and then a plurality of LEDs are disposed on the circumference of the projection to replace the conventional tungsten bulb, due to the plurality of LEDs The projected light is directional, so the inner side of the reflector needs to be matched with the position of each LED to be a reflective surface of a corresponding shape so that it can match the complex LED. The projection of the light and the refraction of the lens on the front side of the body form a standard light shape and illumination. However, since the mounting hole of the base and the rotating joint structure of the lamp holder are in error in production, and the bulb holder is coupled and fixed in the mounting hole of the base by the rotation coupling, it is difficult to control the plurality of LEDs. The position, together with the plurality of LEDs, is fixed on the bulb holder and cannot be adjusted in angular and axial displacement. Therefore, when the bulb holder is rotatably coupled to the base, the position of the LED and the reflector are often generated. The corresponding reflective surface cannot be accurately matched and focused, and thus the light shape and illuminance of the light projected by it are poor, and thus the lighting effect is seriously affected.

The invention is mainly based on solving the conventional knowledge When the lamp structure is changed to use the LED as the light source, the position of the LED is not easily located at a better reflection position during assembly, and the light shape and illuminance of the light projected thereby are relatively poor.

The invention provides a lamp knot The structure comprises a lamp housing, a lamp holder, a socket, a plurality of LEDs and a positioning bolt. Wherein, the lamp housing has a reflector inside to reflect the internal light to the front, and the rear end surface has a coupling hole penetrating into the reflector. The lamp holder is coupled and fixed in the coupling hole in a rotating joint. The lamp holder has a perforation penetrating through one of the front and rear end faces, and has a positioning screw hole penetrating to one of the perforations on the circumferential surface. The back end of the socket has a rod body for rotatably and axially movable through the perforation, and the circumferential surface of the socket has a plurality of accommodating grooves. The plurality of LEDs are respectively combined with the plurality of sockets In the accommodating groove, the light is projected onto the reflecting surface inside the reflector. The positioning bolt is screwed in the positioning screw hole, and the front end can be abutted or away from the circumferential surface of the rod body of the socket by screwing or loosening.

The lamp structure provided by the invention The structural design of the socket can be inserted into the through hole of the lamp socket in a rotatable and axially movable manner, so that the lamp holder is coupled and fixed to the lamp housing in a rotationally coupled manner. After being coupled into the hole, the socket can still be rotated or moved axially to displace the LED thereon to the optimum projection position, and the positioning bolt can be locked after the socket is adjusted to the optimal projection position. The socket is fixed to the socket without any movement, so the present invention has the effect of adjusting the position of the LED so that it can project a good light and illumination.
