Description

Technical Field

[0001] The utility model relates to the technical field of lighting devices, in particular to a lighting lamp. Background Art

[0002] The development of lamps has a long history. From oil lamps and candles to later electric lamps, they have brought great benefits to human production and life.

[0003] With the continuous development of science and technology, lamps are getting better and better in energy-saving technology. Various LED lamps are not only energy-saving but also have advantages such as low heat generation. LED lamps are gradually becoming mainstream lighting lamps. However, even LED lamps are still electrical appliances and will generate heat after being powered on. In particular, the greater the power, the greater the corresponding circuit heat power consumption. It can be understood that power is related to current, and heat power consumption I 2 R, that is to say, the heat generated by the circuit is proportional to the square of the current. Therefore, even if the LED has a relatively small heat generation, its heat generation cannot be ignored as the lighting power increases.

[0004] In current lighting lamps, especially those with higher power, special heat dissipation structures are generally added, such as heat dissipation fins and air-cooling structures, or some are designed to form heat exchange channels between the lampshade and the outside through holes. On the one hand, these heat dissipation structures are relatively complex and costly. On the other hand, if the holes make it impossible for the LED to form a relatively closed structure, long-term use will lead to dust deposition and easily accelerate aging. Therefore, in response to the above problems, we have proposed a lighting lamp to at least partially solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-3 In an embodiment of the utility model, a lighting lamp is proposed, comprising: a lamp holder 101 and a cable 102; the lamp holder 101 is a closed type, and its back is a lamp board 111 made of metal; a circuit board is fitted on the lamp board, and an LED lamp bead 115 is arranged on the circuit board; the first end of the cable 102 is passed through the interior of the lamp holder 101 and is electrically connected to the LED lamp bead 115.

[0031] In this embodiment, the LED lamp beads 115 are illuminated and heat-dissipated by a closed lamp holder 101 and a metal lamp board 111, wherein the metal material on the back of the lamp board 111 helps to improve the heat conduction efficiency, and the closed design helps to reduce dust from entering the interior of the lamp, thereby slowing down the aging process. The LED lamp beads on the circuit board fit the lamp board, which can effectively transfer heat to the lamp board, and use the large area and metal material of the lamp board 111 to dissipate heat. In addition, the closed design also helps to keep the interior of the lamp clean and reduce maintenance requirements; the lamp board 111 made of the above-mentioned metal material, such as aluminum alloy material, and the closed design help to improve the heat conduction efficiency and reduce the accumulation of heat inside the lamp. The closed lamp holder 101 reduces the chance of dust entering the interior of the lamp, thereby extending the service life of the lamp and reducing maintenance. Compared with the traditional heat dissipation fins and air-cooling structure, the design of the closed metal lamp board 111 simplifies the heat dissipation structure and may reduce the manufacturing cost. The closed design helps to protect the LED lamp beads from direct influences of the external environment, such as moisture and chemical corrosion.

[0032] As a preferred implementation method, Figure 3As shown, the lamp holder 101 also includes a scattering cover 112 covering the lamp board 111 to enclose the LED lamp beads 115; the lamp board 111 and the scattering cover 112 are hollow structures; the positioning cover 113 passes through the hollow structure and is connected to the fixing cover 114 arranged on the outside of the lamp board 111 through a thread 171.

[0033] The diffuser 112 helps to even out the light emitted by the LED, reduce direct light and shadows, and provide a softer lighting effect; the light is evenly distributed, which can reduce eye fatigue and improve visual comfort during use. The diffuser 112 made of transparent or translucent materials can be used to design unique decorative lamps to add an artistic atmosphere to the space.

[0034] As a preferred embodiment, the scattering cover 112 is made of a transparent or translucent material; the scattering cover 112 made of a transparent or translucent material can make the lamp itself a decorative element, increase the diversity and beauty of the design, and also ensure the transmittance of light while achieving a scattering effect.

[0035] As a preferred embodiment, the lamp board 111 is further provided with a first positioning hole 116 between the hollow structure and the inner side of the LED lamp bead 115, and the scattering cover 112 is provided with a second positioning hole 121 at a corresponding position; the positioning cover 113 is provided with a positioning post 117; the positioning post 117 passes through the second positioning hole 121 and the first positioning hole 116 in sequence. The first positioning hole 116 and the second positioning hole 121 can simplify the assembly process of the lamp, so that the alignment between the lamp board 111 and the scattering cover 112 can be facilitated during installation, thereby improving production efficiency and accuracy. Through precise positioning and fixing, the stability of the various components of the lamp during use can also be ensured, and damage caused by vibration or impact can be reduced. For example, when the lamp is twisted during use, the scattering cover 112 or the positioning cover 113 can be prevented from rotating alone, thereby ensuring the stability of the structure.

[0036] As a preferred implementation method, Figure 3 As shown, the scattering cover 112 is located at the outer side of the hollow structure and is provided with a recessed structure; the second positioning hole 121 is located in the recessed structure, and the fixing cover 114 is embedded in the recessed structure; the fixing cover 114 is provided with a hook 172 for clamping the light board 111 and the scattering cover 112; the volume can be reduced by the recessed structure, so that the light board 111 and the scattering cover 112 occupy a smaller space in the middle position, the two can be in better contact, and the thickness of the middle part is relatively thin; in addition, the fixing cover 114 is embedded in the recessed structure, which can hide the fixing parts, keep the appearance of the lamp neat and integrated, and make the lamp more compact.

[0037] As an example, the above-mentioned lighting lamp can be installed on the ceiling, elevator car, etc. Taking the elevator as an example, a corresponding installation hole is first opened on the top of the elevator car, wherein the aperture of the installation hole is smaller than the fixing cover 114, but the thread 171 of the positioning cover 117 can pass through the installation hole, and then the fixing cover 114 is connected to the above-mentioned positioning cover through the thread 171, so that the above-mentioned lighting lamp is fixed in the car. It is easy to install and also has a certain anti-theft effect. When removing the lamp, it is necessary to first open the top of the car and unscrew the fixing cover 141 to remove the care lamp. It can also be used in other public places. Since a fixing cover 114 can be set inside a building or a target, the lamp cannot be directly taken away by the outside, which can better play an anti-theft role.

[0038] As a preferred implementation method, Figure 1 and Figure 3 As shown, the fixing cover 114 is provided with concave-convex patterns on the outside. The concave-convex pattern structure can provide a better grip and facilitate operation during installation and maintenance. The concave-convex pattern can increase friction during operation to prevent the cover from being unable to hold tightly or slipping easily during installation.

[0039] As a preferred embodiment, the LED lamp beads 115 are distributed in a ring or in a ring array; the LED lamp beads 115 are COB lamp beads; the ring distribution or COB (Chip on Board) lamp beads can provide more uniform light output and reduce hot spots and dark areas; since COB lamp beads usually have higher light efficiency and better thermal management, they help improve the energy efficiency of the overall lighting system. For example, in residential, office or commercial spaces, lamps with uniform light distribution and high lighting quality can create a comfortable and professional lighting environment; in street lighting, park lighting or building facade lighting, lamps with good heat dissipation and dustproof characteristics can provide a long-lasting and low-maintenance lighting solution.

[0040] As a preferred implementation method, Figures 1 to 3 As shown, the second end of the cable 102 is provided with a plastic connecting terminal 103, which is convenient for plugging into a corresponding connector when used.

[0041] As a preferred embodiment, the scattering cover 112 has a micro-concave structure, which can effectively scatter and distribute the light emitted by the light source, thereby reducing the light spot and uneven brightness. It can also refract and scatter the light, thereby reducing the glare effect of the direct light source on the eyes. In addition, while meeting the optical performance requirements, it can also enhance the appearance design of the product.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
