Description

Technical Field

[0001] This utility model relates to the field of emergency lighting technology, and in particular to a direct-emitting double-arrow underground marker light. Background Technology

[0002] According to fire safety requirements, fire emergency sign lights are required to be installed in or near public buildings for fire emergency evacuation guidance. One type of existing fire emergency sign light is the in-ground type, which has two lighting methods: one is light guide plate lighting, where LED light sources illuminate the light guide plate and then project the light outwards through a light-transmitting element; the other is direct light emission, where an LED light source is placed below the light-transmitting element, directly illuminating the element. Direct light emission in-ground lights have fewer components, mature technology, and are therefore very inexpensive. However, with the formal implementation of GB51309, regulations stipulate that large buildings must use intelligent sign lights, meaning the arrows on the sign lights can be controlled to turn on and off according to usage needs, and the light from two arrows should not interfere with each other. Since direct light emission in-ground lights directly illuminate the entire cavity with LED light sources and cannot switch arrows, they cannot be applied to intelligent sign lights. Utility Model Content

[0003] The purpose of this utility model is to provide a direct-emitting double-arrow underground marker light that is simple in structure, robust, has clearly switchable arrows, and whose light emitted by each arrow does not interfere with each other.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a direct-light-emitting double-arrow underground marker light, comprising: a housing with a light-emitting cavity;

[0005] A marker is placed over the light-emitting cavity. The marker includes an arrow and a light-blocking part. The arrow is composed of a first arrow and a second arrow. The light-blocking part is disposed between the first arrow and the second arrow. The light-blocking part extends towards the bottom of the housing and divides the light-emitting cavity into two non-cross-lit cavities, a first cavity and a second cavity. The first arrow is disposed above the first cavity, and the second arrow is disposed above the second cavity.

Detailed Implementation

[0028] The technical solution of this utility model will be further described below with reference to specific embodiments.

[0029] like Figures 1 to 5As shown, a direct-emitting double-arrow underground marker light includes: a housing 1 with a light-emitting cavity 11; a marker 2 covering the light-emitting cavity 11, the marker 2 including an arrow 3 and a light-blocking part 4, the arrow 3 being composed of a first arrow 31 and a second arrow 32, the light-blocking part 4 being disposed between the first arrow 31 and the second arrow 32, the light-blocking part 4 extending towards the bottom of the housing 1 and dividing the light-emitting cavity 11 into two non-cross-lit cavities, a first cavity 12 and a second cavity 13, the first arrow 31 being disposed above the first cavity 12, and the second arrow 32 being disposed above the second cavity 13; the arrow 3 being made of light-transmitting / light-guiding plastic, the light-blocking part 4 being made of opaque plastic, and the marker 2 being formed by two-color injection molding; a light source plate 5 disposed inside the housing 1, the light source plate 5 having two or more LED light sources 51; and a marker plate 7 disposed above the marker 2. The light-blocking part 4 divides the light-emitting cavity 11 into two non-cross-flowing first cavities 12 and second cavities 13. In case of emergency, the LED light source 51 can be controlled to turn on and off according to usage requirements. Due to the obstruction of the light-blocking part 4, the light from the first cavity 12 cannot be transmitted to the second cavity 13. The light converges to the first arrow piece 31 above the first cavity 12, making the light displayed by the first arrow piece 31 clearer, and the second arrow piece 32 has no light effect. Since the underground marker light is installed in the corridor or passageway, it needs to have great load-bearing capacity. The marker piece 2 is made by two-color injection molding. Although the two arrow pieces 3 are not connected to each other, they can also be connected by the light-blocking part 4 to ensure the hardness of the marker piece 2, thereby ensuring the service life of the lamp.

[0030] In some embodiments, for ease of production, the first arrow member 31 and the second arrow member 32, made of light-transmitting plastic, are connected by a small area. Since the space for light transmission is very small, the light blocking mainly relies on the light-blocking part 4. In this case, the first arrow member 31 and the second arrow member 32 should also be considered as not connected to each other.

[0031] In some embodiments, the light-blocking part 4 is detachable below the light-blocking groove on the back of the marker 2. The light-blocking part 4 and the light-blocking groove are disposed between the first arrow part 31 and the second arrow part 32, and the top of the light-blocking part 4 enters the light-blocking groove.

[0032] The light source plate 5 is disposed at the bottom of the housing 1. The light-blocking part 4 evenly distributes the LED light source 51 in the first cavity 12 and the second cavity 13. The number of LED light sources 51 in the first cavity 12 is equal to the number of LED light sources 51 in the second cavity 13. This structure ensures that the light flux in the first cavity 12 and the light flux in the second cavity 13 are the same, thereby ensuring that the light flux shown by the two arrow parts 3 is consistent, so that the light presented by the product is better.

[0033] The light-blocking part 4 is provided with a notch 41, and the light source plate 5 is disposed within the range of the notch 41. The position and / or size of the notch 41 is set according to the position and / or size of the light source plate 5. This structure prevents the light from the first cavity 12 from entering the second cavity 13 from the side of the light source plate 5, and ensures that there is no light crosstalk between the first cavity 12 and the second cavity 13.

[0034] In some embodiments, the light source plate 5 is disposed on the side of the light-emitting cavity 11, and the light from the LED light source 51 irradiates the center of the housing 1. The number of LED light sources 51 in the first cavity 12 is equal to the number of LED light sources 51 in the second cavity 13.

[0035] The shape of the light-blocking part 4 is adapted to the cross-sectional shape of the light-emitting cavity 11; the side of the light-emitting cavity 11 is a slope or an arc surface; or, the side of the light-emitting cavity 11 is a vertical surface perpendicular to the bottom surface of the light-emitting cavity 11; this structure can ensure that there is no light leakage between the first cavity 12 and the second cavity 13.

[0036] The light-blocking part 4 contacts the bottom of the housing 1. In addition to preventing light from passing between the first cavity 12 and the second cavity 13, it also supports the marker 2, giving the marker 2 a supporting force in the middle and strengthening the load-bearing capacity of the entire lamp.

[0037] The marker component 2 also includes a frame 6, which is circular in shape. The light-blocking part 4 is disposed in the middle of the frame 6 and divides the middle of the frame 6 into two light-transmitting holes 61. The shape of the arrow component 3 is adapted to the shape of the light-transmitting holes 61. The arrow component 3 is disposed in the light-transmitting holes 61 and is semi-circular. The frame 6 and the light-blocking part 4 are integrally injection molded from the same type of plastic. The frame 6 can make the connection between the first arrow 31 and the second arrow 32 more secure and strengthen the load-bearing capacity of the entire lamp. Since the arrow component 3 is made of light-transmitting plastic, the light entering the arrow component 3 can be emitted outward from the side of the arrow component 3, resulting in resource waste. The frame 6 can reflect the light emitted from the edge of the arrow component 3, so that the light can be fully utilized and the light emitted from the front of the arrow component 3 can be more uniform.

[0038] The outer side of the housing 1 is provided with a first assembly surface 14, which forms a stepped shape with the outer side of the housing 1. The radius of the first assembly surface 14 is smaller than the radius of the outer side of the housing 1. The frame 6 is provided with a downwardly extending second assembly surface 62, which covers the first assembly surface 14. The first assembly surface 14 is disposed within the second assembly surface 62. The outer side of the second assembly surface 62 and the outer side of the housing 1 are located on the same vertical plane. This structure can strengthen the overall hardness of the sign 2 and enhance the load-bearing capacity of the entire lamp.

[0039] The arrow component 3 has an upward-protruding arrowhead 33 above it, and the sign plate 7 has a hollowed-out sign hole 71, with the arrowhead 33 located inside the sign hole 71.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
