Light guide structure for realizing high brightness by low-power LED

Abstract

The invention discloses a light guide structure for realizing high brightness by a low-power LED. The light guide structure comprises a support and a light condenser, a PCBA is arranged on the top of the support, an LED lamp wick is installed on the top of the PCBA through an installation base, the light condenser is arranged on the outer side of the top of the PCBA, an optical reflection mirror face is glued in the light condenser, and a light guide column is arranged on the top of the light condenser in a sleeved mode. Compared with a conventional LED lighting light guide mode, the condenser is additionally arranged, the condenser can play a role in collecting light which cannot be directly emitted into the light guide and reflecting the light into the light guide again, meanwhile, the condenser can also reduce the effect that deviation exists between the position relation of a traditional light guide and an LED and actual assembly matching, and therefore the LED optical utilization rate is increased. The objective of low-power high brightness is achieved and the light guide structure is suitable for being widely popularized and used.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a light guide structure for realizing high brightness with low-power LEDs. Background technique [0002] Car headlights, also known as car headlights and car LED daytime running lights, as the eyes of a car, are not only related to the external image of a car owner, but also closely related to driving at night or in bad weather conditions. Currently, there are In the matching structure of light guides and LEDs used in car lights. [0003] However, the disadvantages of the existing LED car lights are: 1. The light emitted by the LED is incident into the light guide at about 90 degrees, and the light at a certain angle with the LED cannot be incident into the light guide. 2. Most of the light guide and PCBA are not installed. On the same part, due to mold reasons, it is impossible to make a direct limit structure between the light guide and PCBA, resulting in a large size chain...

Problems solved by technology

[0003] However, the disadvantages of the existing LED car lights are: 1. The light emitted by the LED is incident into the light guide at about 90 degrees, and the light at a certain angle with the LED cannot be incident into the light guide. 2. Most of the light guide and PCBA are not installed. On the same part, due to mold reasons, it is impossible to make a direct limit structure between the light guide and PCBA, resulting in a large size chain between the LED and the light guide after the actual installation, and there is a certain deviation in the design position of the LED and the light guide after the actual product is installed. To this end, we propose a low-power LED to achieve high-brightness light guide structure
