Description

Technical Field

[0001] The utility model relates to the field of vehicle-mounted working lights, in particular to a novel optical structure of a vehicle-mounted working light that realizes multiple light patterns in the same reflector cup. Background Technique

[0002] At present, there is only one LED in one lamp cup of a vehicle-mounted working light, and the light spot projected has only one light pattern. Or the lamp needs to be disassembled to replace the lamp cup or secondary optical lens to change the light pattern, and the required light pattern cannot be changed by switching through a switch during driving.

[0003] Regarding the above related technologies, the inventor believes that the following defects exist:

[0004] For current vehicle-mounted working lights, especially off-road auxiliary driving lights, the required light needs to be projected far. If the light needs to be projected far, the light needs to be made super-concentrated. To meet this requirement, the reflector cup is usually designed as a super-concentrated deep lamp cup. The deep lamp cup can make the light very concentrated, but the projected light spot is very small, that is, the illumination range will be very small (only one point). If it is not designed as a super-concentrated deep lamp cup reflector cup with a larger angle, the projected light spot will be larger, that is, the central light intensity will not be strong enough and the light will not be projected far enough. To solve this problem, we comprehensively utilize the advantages and disadvantages of the super-concentrated deep lamp cup: if super-concentration is to be achieved, the lamp beads need to be accurately placed at the focus of the reflector cup. If they deviate from the focus, the projected light will shift, the central light spot will be larger, the illuminance will be smaller, and the illumination distance will not be so far. Content of the Utility Model

[0005] To improve the above problems, the present application provides a novel optical structure of a vehicle-mounted working light that realizes multiple light patterns in the same reflector cup. In the super-concentrated reflector cup, multiple lamp beads are arranged. The middle lamp bead is just at the focus position of the reflector cup, which can project the light very concentrated and far. The surrounding lamp beads deviate from the focus of the reflector cup, and the projected light spot will be larger, and the obtained illumination range will be wider.

[0006] The present application provides a novel optical structure of a vehicle-mounted working light that realizes multiple light patterns in the same reflector cup, adopting the following technical solutions: A novel optical structure of a vehicle-mounted working light that realizes multiple light patterns in the same reflector cup, including a lamp housing, a light source driving board, driving board fixing screws, and LED lamp beads. The light source driving board is fixed inside the lamp housing through the driving board fixing screws. An ultra-concentrating deep lamp cup is installed on the light source driving board. There are positioning holes and positioning posts between the ultra-concentrating deep lamp cup and the light source driving board. Multiple LED lamp beads are arranged in the ultra-concentrating deep lamp cup. The multiple LED lamp beads include main illumination LEDs and secondary illumination LEDs.

[0007] Further setting, the light source driving board further includes: a driving board, a main illumination LED, and a secondary illumination LED. The driving board is electrically installed with the main illumination LED, and the driving board is electrically installed with the secondary illumination LED.

[0008] Further setting, the main illumination LED is located at the optical focus of the super-condensing deep lamp cup.

[0009] Further setting, the driving board is electrically connected to an external power source.

[0010] Compared with the related technology, a novel optical structure of a vehicle-mounted work lamp that realizes multiple light patterns in the same reflector cup provided by the present utility model has the following beneficial effects:

[0011] The present utility model provides a novel optical structure of a vehicle-mounted work lamp that realizes multiple light patterns in the same reflector cup.

[0016] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings. The typical embodiments of the present utility model are given in the drawings.

[0017] Embodiment 1:

[0018] As Figure 1 shown, a novel optical structure of a vehicle working lamp that realizes multiple light patterns in the same reflector cup according to the present utility model includes a lamp housing 1, a light source driving board 2, driving board fixing screws 3, and LED lamp beads. The light source driving board 2 is fixed inside the lamp housing 1 through the driving board fixing screws 3. A super-condensing deep reflector cup 4 is installed on the light source driving board 2. There are positioning holes and positioning posts between the super-condensing deep reflector cup 4 and the light source driving board 2. Multiple LED lamp beads are arranged in the super-condensing deep reflector cup 4. The multiple LED lamp beads include a main illumination LED 22 and a secondary illumination LED 23.

[0019] As Figure 2 shown, the light source driving board 2 further includes: a driving board 21, a main illumination LED 22, and a secondary illumination LED 23. The driving board 21 is electrically installed with the main illumination LED 22, and the driving board 21 is electrically installed with the secondary illumination LED 23.

[0020] As Figure 3 shown, the main illumination LED 22 is located at the optical focus of the super-condensing deep reflector cup 4. The driving board 21 is electrically connected to an external power source.

[0021] In implementation, there are positioning holes and positioning posts between the super-condensing deep reflector cup 4 and the light source driving board 2, so that they cannot move horizontally. After the super-condensing deep reflector cup 4 is installed, at this time, the main illumination LED 22 is located at the optical focus of the super-condensing deep reflector cup 4. When the main illumination LED 22 is powered on, the emitted light is reflected by the super-condensing deep reflector cup 4 to form a very small condensed light spot, and the illuminance will be very strong, and the light will be projected very far; similarly, when the secondary illumination LED 23 is powered on, the emitted light is reflected by the super-condensing deep reflector cup 4, and the projected light spot will shift towards the center point to form a larger light spot. Thus, in the same reflector cup, a hybrid driving light that can simultaneously obtain both a condensed light spot that can be projected very far and a larger light spot with a larger illumination range can be obtained.

[0022] The advantages of this technical solution in practical applications include but are not limited to the following points:

[0023] 1. Solved the technical bottleneck that the current off-road auxiliary driving lights have a too small illumination range that can be projected far, while the lights with a large illumination range cannot be projected far;

[0024] 2. Realized this lighting structure in the same reflector cup, and in the same lamp cup, a hybrid driving light that can simultaneously obtain both a condensed light spot that can be projected very far and a larger light spot with a larger illumination range can be obtained;

[0025] 3. Can realize the switching between different light patterns at any time by controlling the on / off of the two types of lamp beads, greatly reducing the overall size of the lamp and increasing the applicable range of the lamp.

[0026] In this technical solution, the LED lamp beads are divided into the main illumination LED 22 and the auxiliary illumination LED 23. The main illumination LED 22 is in the middle, and the auxiliary illumination LED 23 is arranged around it. During assembly, the main illumination LED 22 is just installed at the focus of the ultra-concentrating deep lamp cup 4. When the main illumination LED 22 is lit, the emitted light is reflected by the ultra-concentrating deep lamp cup 4, forming a very small concentrated light spot, and the illuminance will be very strong, and the light can be projected very far. The auxiliary illumination LED 23 is around the main illumination LED 22, that is, it is deviated from the focus of the ultra-concentrating deep lamp cup 4. When the auxiliary illumination LED 23 is lit, after being reflected by the ultra-concentrating deep lamp cup 4, the projected light spot will shift towards the center point, forming a larger light spot. If both types of LEDs are lit at the same time, what is obtained is a mixed light pattern of a small ultra-concentrated light spot in the middle and a larger illumination range around. The two illumination LEDs can be divided into two circuits to be controlled separately, and different illumination effect light spots can be obtained through a switching switch.
