Large illuminating lamp capable of effectively strengthening light focusing effect

Abstract

The invention discloses a large illuminating lamp capable of effectively strengthening a light focusing effect. The large illuminating lamp comprises an LED light-emitting unit which comprises a hemispherical lens and an LED chip part positioned below the hemispherical lens; an SMD type pin for providing power supply to the LED chip part is arranged on the bottom of the LED chip part; and the LED light-emitting unit is internally arranged on the bottom of a light guide cover and is fixedly connected with the light guide cover. According to the large illuminating lamp disclosed by the invention, the LED illuminating device utilizes the light guide cover above the LED light-emitting unit, so that the light guide effect and the light focusing effect of the whole light guide device can be greatly improved, light of an LED is effectively utilized, and a light leakage rate is reduced.

Description

technical field [0001] The invention relates to a vehicle lamp, in particular to a large-scale illuminating lamp which can effectively enhance the light-gathering effect. Background technique [0002] Large lights that effectively enhance the spotlight effect are gradually replacing traditional halogen lights and becoming the basic standard configuration of cars. However, most of the existing large-scale lighting lamps that effectively enhance the spotlight effect are integrally formed or assembled by gluing each component, which has the disadvantages of complex structure and difficult assembly; The adjustment is mainly realized by the lamp sliding back and forth in the chute of the housing. If the width of the chute is large, the lamp tends to loosen, resulting in inaccurate adjustment of far and near beams. If the width of the chute is small, the lamp is easy to get stuck. In the chute, the chute is worn out, and what is more, it causes the failure of the adjustment. And...

However, most of the existing large-scale lighting lamps that effectively enhance the spotlight effect are integrally formed or assembled by gluing each component, which has the disadvantages of complex structure and difficult assembly; The adjustment is mainly realized by the lamp sliding back and forth in the chute of the housing. If the width of the chute is large, the lamp tends to loosen, resulting in inaccurate adjustment of far and near beams. If the width of the chute is small, the lamp is easy to get stuck. In the chute, it will wear the chute, and even cause the failure of the adjustment

Moreover, limited by the existing level of precision machining, it is difficult to improve the machining accuracy of the chute, and it is difficult to significantly improve the telescopic distance of the far and near light adjustment of the large-scale lighting that effectively enhances the concentrating effect.
