Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the embodiments of the present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1-4, an LED headlamp for achieving an internal atmosphere lighting effect has:
the first end of the lower cover is provided with an opening;
a lens mounted on the opening of the lower cover;
the reflector mounting bracket is arranged on the lower cover;
the reflecting mirror is arranged on the reflecting mirror mounting bracket;
the circuit board is arranged on the lower cover and is positioned below the reflecting mirror;
a light source mounted on the circuit board;
the stray light reflecting surface is arranged on the lower cover and can reflect stray light reflected by the reflecting mirror; the stray light reflecting surface faces the upper opening of the lower cover;
the upper cover of the lens module is connected with the lower cover and covers the upper opening of the lower cover;
the upper cover plaque of the lens, connect with upper cover of the lens module; the upper cover plaque of the lens is made of transparent materials;
the upper cover of the mirror module and the decorative plate of the upper cover of the lens are provided with openings, and the openings are light transmission channels;
and the rear cover is arranged on the lower cover and is positioned at the rear part of the lower cover.
The circuit board also comprises a radiator, wherein the radiator is arranged on the lower cover and is positioned at the lower part of the circuit board.
And a fan mounted on the rear cover.
The light transmittance of the upper cover decorative plate of the lens is 50-70%.
The upper cover decorative plate of the lens can adjust the brightness and the light color of ambient light by adding the light diffusion material and the color master. The light intensity of the atmosphere lamp formed by the stray light reflected by the stray light reflecting surface is below 50 lm. An auxiliary light source is also arranged on the circuit board, and the auxiliary light source is a single LED or an elongated optical fiber with the power below 0.2W. The light intensity after superposition of the light source and the stray light meets the requirement of the regulation.
A stray light reflecting surface is newly added on a reflector mounting bracket of the lens module, as shown in FIG. 2. And holes are formed in the middle of the upper cover of the lens module and below the decorative plate of the upper cover of the lens, and a light transmission channel is formed above the reflecting surface and simultaneously serves as a heat dissipation channel of the LED light source. The material of the upper cover decorative plate of the lens is adjusted to be colored transparent PC, the light transmittance is controlled to be about 60%, and the light transmittance of the lens during lighting is ensured. The brightness and the light color of the ambient light can be adjusted by adding the light diffusion material and the color master. The light effect of the atmosphere lamp cannot influence the normal operation of the functional lamp, and the light intensity of the atmosphere lamp is recommended to be controlled below 50 lm.
A group of weak light sources (single LED power is below 0.2W or slender optical fibers) are additionally arranged in the headlamp. The stray light of the lens module is reasonably utilized to realize the atmosphere light effect inside the headlamp. The light source-like design is realized by utilizing the stray light collected by the reflecting surface and the transparent scheme of the upper cover of the lens module.
