Embodiment Construction

[0017] Such as Figure 1 to Figure 3 As shown, design the LED car light structure, design the shape and size of the reflector cup according to the shape of the designed light spot and the distance formed by the light spot, and then determine the angles formed by the four reflection planes and the reference axis 11 of the lamp respectively, and design four reflections plane, each reflection plane forms a certain angle with the reference axis of the lamp, the first reflection plane 1 and the second reflection plane 2 are symmetrical based on the reference axis 11 of the lamp, and form an angle δ with the reference axis 11 of the lamp, and the angle range of δ is 75-86° , the third reflection plane and the fourth reflection plane 4 are symmetrical based on the reference axis 11 of the lamp, and form an angle β with the reference axis 11 of the lamp, and the angle range of β is 77-87°. structure, then select and install four high-power LEDs, the power of each LED is 7-10W, the lum...

Abstract

The invention discloses a projection type LED automobile high beam. The high beam is characterized in that: the high beam comprises four high-power LEDs, each of which is made of a single chip; the high beam is provided with four reflection planes, each LED corresponds to a different reflection plane, the direction of the central emergent light emitted by each LED is perpendicular to the corresponding reflection plane, the first reflection plane and the second reflection plane are symmetric based on the datum axis of the high beam, both the first reflection plane and the second reflection plane make the angle Delta of 75 to 86 degrees with the datum axis of the high beam, the third reflection plane and the fourth reflection plane are symmetric based on the datum axis of the high beam, and both the third reflection plane and the fourth reflection plane make the angle Beta of 77 to 87 degrees with the datum axis of the high beam. Since the light of the high beam is concentrated, the projection angle is small, and the distance is long. The high beam can replace conventional automobile high beams.

Description

technical field [0001] The invention relates to a lamp, in particular to a projection type LED automobile high beam lamp. Background technique [0002] At present, the commonly used automobile headlights are mainly based on xenon lamps and halogen lamps, and the market sales volume is relatively large. Compared with other types of lamps, xenon car lights and halogen car lights have problems such as the need for a professional starting power supply and short service life. At present, the luminous efficiency of LEDs in industrialized production has reached 100 lumens / watt. With the continuous advancement of technology, its luminous efficiency will be greatly improved. In addition, the color temperature of LEDs has a large range of changes, that is, the color temperature of LEDs is easy to control, and LEDs have working characteristics. Low voltage, low power consumption, small size. Contents of the invention [0003] The object of the present invention is to overcome the d...
