Description

FIELD OF THE PRESENT INVENTION

The present invention relates to a lamp, and more particular to a lamp suitable to be mounted on a lamp attachment such as a ceiling, which has a fireproof unit used for reducing the spread speed of a fire when a fire disaster caused by the lamp occurs.

BACKGROUND OF THE PRESENT INVENTION

A Ceiling lamp, which is a kind of common lighting lamp in our daily lives. , can be mounted on a ceiling for indoor illumination. The ceiling lamp can be classified into an adjustable ceiling lamp with adjustable lighting angles or a fixed ceiling lamp with a fixed lighting angle based on whether the lighting direction of the light beams thereof can be adjusted or not. Due to the fact that the lighting angle of a fixed ceiling lamp is fixed once the fixed ceiling lamp is installed, so that it is very inconvenient for a user to adjust the lighting angle when necessary. A current adjustable ceiling lamp can realize multi-angle indoor illumination. When a user adjusts the lighting angles, the user can adjust the lighting angle of the lamp manually or automatically based on predetermined parameters, so as to realize the multi-angle illumination.
A conventional adjustable ceiling lamp usually includes a light emitting element to provide a lighting source; an adjustment element for a user to adjust the lighting angles of the lamp; a fixing unit for installing the lamp on a ceiling for illumination; a connecting element for connecting the fixing unit with the adjusting element; and a heat dissipating element for preventing an excessive accumulation of the heat during the operation of the light emitting element, and for reducing the temperature of the light emitting element. Components of this kind of lamp are usually made of plastic, aluminium metal or aluminium alloy, et al. This kind of lamp which is made of the above mentioned material is rust free, and has a light quality and a beautiful appearance. But this kind of ceiling lamp has a lot of disadvantages. First of all, a ceiling lamp is mounted at a ceiling in an embedded manner in consideration of the aesthetic appearance, so that the lamp gives a considerable adverse effect to the entire fireproof ability of the fireproof ceiling. If components of the lamp are made of material which can only bear temperature not higher than 600°C, such as plastic, aluminium metal and aluminium alloy, once a fire disaster occurs and the temperature amounts to be higher than 600°C, the components of the lamp will melt. A Flame below the ceiling will spread to the position above the ceiling through the cracks formed by the melting of the lamp. On the other hand, a flame above the ceiling will spread to the position below the ceiling. Either of the two conditions will induce the fast spreading of the fire disaster and cause a heavy loss. Secondly, to realize the lighting angel adjustment of the adjustable lamp, it is usually necessary to provide some space between the adjustment element and the retention element of the lamp, which enables the flame in the fire disaster to easily spread to the position above the ceiling through the space, then the flame will spread and burn up quickly, and heavy loss may occur before disaster relief personnel and firefighters arrive at the scene. Thirdly, after the components of the lamp melt down, the melted components will fall off from the ceiling, which will give risk to the safety of the personnel in the room. In addition, after the melted components of the lamp fall off from the ceiling, combustible substance in the room will be burned, and the fire will quickly spread in the room. Finally, after the ceiling lamp was melted, a hole allowing wind going therethrough will be formed in the ceiling, which will also speed up the quick spreading of the fire.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The following description is disclosed to enable any person skilled in the art to make and use the present invention. Preferred embodiments are provided in the following description only as examples and modifications will be apparent to those skilled in the art. The general principles defined in the following description would be applied to other embodiments, alternatives, modifications, equivalents, and applications without departing from the spirit and scope of the present invention.
Referring to FIGS. 1 to 8 of the drawings, a lamp according to a preferred embodiment of the present invention is illustrated, wherein the lamp comprises a retention unit 10 which is suitable to be fixed to a lamp attachment such as a ceiling, an adjustment element 20 used for adjusting the direction of light beams emitted by a light emitting element 60, and a heat dissipation element 30 for dissipating heat.
As shown in FIGS. 1 to 3, the retention unit 10 of the lamp according to the preferred embodiment of the present invention forms a first containing chamber 100 running from a top to a bottom. At the same time, the retention unit 10 is suitable to be mounted to a lamp attachment, such as a ceiling, to fix the lamp at a proper position.
It is worth noting that the retention unit 10 of the lamp is made of high-temperature-resistant material, which keeps its shape in a longer period of time even in a high-temperature environment, so as to prevent the lamp according to the present invention from falling off a lamp attachment, such as a ceiling, in the high-temperature environment, due to the melting of the retention unit 10.
The adjustment element 20 is pivotally contained at the first containing chamber 100 formed by the retention unit 10, wherein the adjustment element 20 comprises an adjustment body 21 which is pivotally contained at the first containing chamber 100 formed by the retention unit 10.. The adjustment body 21 forms a light passage 211 suitable to allow the light beams emitted by the light emitting element 60 to pass therethrough. Furthermore, the adjustment element 20 further comprises a lower end portion 22 provided at a bottom of the adjustment body 21, wherein the adjustment body 21 together with the lower end portion 22 forms a second containing chamber 200 with an upper opening. At the same time, the lower end portion 22 forms a light outlet 221 communicating with the light passage 211, wherein the light outlet 221 allows the light beams emitted by the light emitting element 60 to pass therethrough.
The heat dissipation element 30 comprises a heat dissipation portion 31 and a mounting portion 32 extending from the heat dissipation portion 31. The light emitting element 60 is provided at the bottom of the mounting portion 32 of the heat-dissipation element 30 while the bottom of the mounting portion 32 of the heat-dissipation element 30 is suitable to be contained at the second receiving chamber 200 formed by the adjustment element 20 to couple the bottom of the heat-dissipation element 30 and the adjustment element 20. Furthermore, the mounting portion 32 is extended downwardly from the heat dissipating portion 31 and forms a third receiving chamber 300 which has a lower opening. The heat dissipation portion 31 of the heat dissipation element 30 provides a wire passage 33. A power wire passes through the wire passage 33 and electrically connects with the light emitting element 60 provided at a top position of an inner wall of the third receiving chamber 300 to supply electrical power for the light emitting element 60. Furthermore, the heat dissipation portion 31 of the heat dissipation element 30 comprises a dissipation body 311 and a offset of sheet-shaped heat dissipation members 312 provided at the dissipation body 311. The sheet heat dissipation members 312 are provided to improve the heat dissipating performance of the heat dissipation element 30.
Preferably, the mounting portion 32 of the heat dissipation element 30 and the adjustment element 20 are integrated with each other to form a one-piece structure, so that when a user adjusts the position of the adjustment element 20 of the lamp to direct the light beams passing through the light passage 211 of the adjustment element 20 to project with a desired angle, the heat dissipation element 30 will pivotally rotate along with the pivotal rotation of the adjusting element 30, so as to reduce operation procedures. Preferably, the mounting portion 32 of the heat dissipation element 30 is integrally connected with the adjustment body 21 of the adjustment element 20.
It can be understood that the mounting portion 32 of the heat dissipation element 30 can also be integrally connected with the lower end portion 22 of the adjustment element 20 or can be integrally connected with both of the adjustment body 21 of the adjustment element 20 and the lower end portion 22 of the adjustment element 20, so that when a user adjusts the position of the adjustment element 20 of the lamp to direct the light beams passing through the light passage 211 of the adjustment element 20 to project with a desired angle, the heat dissipation element 30 will pivotally rotate along with the pivotal rotation of the adjusting element 30, so as to reduce operation procedures.
It is worth mentioning that the position of the heat dissipation portion 31 of the heat dissipation element 30 may be higher than the position of a top end of a second retention element 12 of the retention unit 10 of the lamp to help the heat dissipation element 30 to dissipate heat. Furthermore, the position of the mounting portion 32 of the heat dissipation element 30 may be higher than the position of a top end of a second retention element 12 of the retention unit 10 of the lamp to help the heat dissipation element 30 to dissipate heat.
As shown in FIGS. 3 to 4 of the drawings, the lamp according to the preferred embodiment further comprises a heat resistant unit 40, wherein the heat resistant unit 40 comprises a first heat resistant element 41 received at the second receiving chamber 200 formed by the adjustment element 20. The first heat resistant element 41 , which is provided between the adjustment element 20 and the mounting portion 32of the heat dissipation element 30, is made of high-temperature resistant material to prevent it from melting and to keep its shape in a relatively long period of time in a high-temperature environment and to further reduce the speed of melting of the components of the lamp and to prevent the lamp from breaking up. Furthermore, the first heat resistant element 41 comprises a first heat resistant portion 411 and a second heat resistant portion 412 extended inwardly from a lower end of the first heat resistant portion 411, wherein the first heat resistant portion 411 is provided between an outer side of the mounting portion 32 of the heat dissipation element 30 and an inner side of the adjustment body 21 of the adjustment element 20. The second heat resistant portion 412 is provided below the mounting portion 32 of the heat dissipation element 30. In other words, the second heat resistant portion 412 of the first heat resistant element 41 is provided between the mounting portion 32 of the heat dissipation element 30 and the lower end portion 22 of the adjustment element 20 to prevent the fire caused by a fire disaster passing through the gap between the adjustment element 20 and the heat dissipation element 30 to spread to the position above the lamp.
It is worth mentioning that the outer shape of the first heat resistant element 41 can be the same as the outer shape of the adjustment element 20 of the lamp and the first heat resistant element 41 is provided inside the adjustment element 20, wherein the second heat resistant portion 412 of the first heat resistant element 41 has a light exit 410 overlapping with the light outlet 221 of the adjustment element 20 to make the light beams emitted by the light emitting element 60 provided at the lamp pass through the light exit 410 and the light outlet 221 of the adjustment element 20 , so as to reach the external of the lamp. In other words, the first heat resistant element 41 is shaped to match with the second receiving chamber 200 formed by the adjustment element 20, so that the first heat resistant element 41 is suitable to be received in the second receiving chamber 200 formed by the adjustment element 20, and the outer side of the first heat resistant element 41 is close to the inner side of the adjustment element 20. The light exit 410 defined by the second heat resistant portion 412 of the first heat resistant element 41 allows the light beams emitted by the light emitting element 60 to pass therethrough to reach the light outlet 221 of the adjustment element 20.
As shown in FIGS. 3 to 4 of the drawings, the heat resistant unit 40 of the lamp according to the preferred embodiment of the present invention further comprises a second heat resistant element 42 provided at the third receiving chamber 300 formed by the heat dissipation element 30. The second heat resistant element 42 is made of high-temperature resistant material. The second heat resistant element 42 is extended downwardly from a rear side of the light emitting element 60 which is provided at the inner wall around the third receiving chamber 300 to the first heat resistant element 41 of the heat resistant unit 40 along the inner wall around the third receiving chamber 300 light emitting , so that the first heat resistant element 41 of the heat resistant unit 40 and the second heat resistant element 42 of the heat resistant unit 40 define a safe chamber 400 to reduce the spreading speed of the fire caused by the fire disaster in the third receiving chamber 300.
It is worth noting that a vertical length of the security chamber 400 is greater than a transverse width of the security chamber 400, so the journey of the fire caused by the fire disaster in the security chamber 400 is lengthened and the time for the fire reaching the top of the security chamber 400 is lengthened, so that the spreading speed of the fire caused by the fire disaster in the third receiving chamber 300 is reduced.
As illustrated in FIGS. 1 to 4 of the drawings, the lamp according to the preferred embodiment of the present invention further comprises a lens 50 provided at the lower end portion 22 of the adjustment element 20 of the lamp. The size of the lens 50 is not smaller than the size of the light outlet 221 of the adjustment element 20, so the lens 50 completely seals the light outlet 221, and thus the security chamber 400 defined by the first heat resistant element 41 of the heat resistant unit 40 and the second heat resistant element 42 of the heat resistant unit 40 is sealed by the lens 50 to prevent the fire caused by the fire disaster spreading to the above of the lamp. In other words, due to the first heat resistant element 41 of the heat resistant unit 40 and the second heat resistant element 42 of the heat resistant unit 40 are both made of high-temperature resistant material, and they can keep their shapes in a relative long period of time, so that the heat resistant unit 40 forms a heat resistant mechanism which reduces the speed of the fire caused by the fire disaster spreading to the position above the lamp. Hence, the speed of the fire caused by the fire disaster spreading to the position above the lamp is reduced.
As illustrated in FIGS. 7 and 8 of the drawings, the retention unit 10 of the lamp according to the preferred embodiment of the present invention comprises a first retention element 11 and a second retention element 12 provided at an outer side of the first retention element 11. The second retention element 12 is suitable to be mounted to a lamp attachment, such as a ceiling. The first retention element 11 forms a first receiving chamber 100which is used to pivotally receive the adjustment element 20, so that the adjustment element 20 is pivotally provided at the first receiving chamber 100.
Furthermore, the lamp according to the preferred embodiment of the present invention comprises the light emitting element 60 which is provided at a top position of the inner wall around the third receiving chamber 300 formed by the heat dissipation element 30 of the lamp. The light beams emitted by the light emitting element 60 are suitable to project out through the light outlet 221 of the adjustment element 20. Preferably, the light emitting element 60 is an LED lighting member.
As shown in FIGS. 4 to 6 of drawings, the lamp according to the preferred embodiment of the present invention further comprises a fireproof unit 70 which comprises a first fireproof element 71 provided between the retention unit 10 and the adjustment element 20. An outer side of the first fireproof element 71 provided between the retention unit 10 and the adjustment element 20 is shaped and designed to match with a shape of an inner side of the retention unit 10 and an inner side of the fireproof unit 70 of the fireproof unit 70 is shaped and designed to match with a shape of an outer side of the adjustment body 21 of the adjustment element 20, so that the first fireproof element 71 of the fireproof unit 70 is suitable to be provided between the retention unit 10 and the adjustment element 20. Hence, when the first fireproof element 71 is heated to swell in a high-temperature environment, the first fireproof element 71 seals a gap between the retention unit 10 and the adjustment element 20 to prevent the fire caused by the fire disaster quickly spreading to the position above the lamp through the gap between the retention unit 10 and the adjustment element 20. Furthermore, a position of the top of the second retention element 12 of the retention unit 10 of the lamp may be higher than a position of the top of the first retention element 11. The first fireproof element 71 of the fireproof unit 70 is provided between the second retention element 12 of the retention unit 10 and the adjustment element 20. The first fireproof element 71 is made of heat-swellable material, which swells in a high temperature environment to form a sealing which seals the gap between the retention unit 10 and the adjustment element 20. Therefore, the first fireproof element 71 prevents the fire caused by the fire disaster from spreading quickly to the outside of the lamp through the gap between the retention unit 10 and the adjustment element 20. Preferably, the first fireproof element 71 of the fireproof unit 70 is provided at the outer side of the adjustment element 20 of the lamp, and the first fireproof element 71 does not contact with the adjustment element 20 of the lamp to interfere the pivotal movement of the adjustment element 30. Preferably, the first fireproof element 71 of the fireproof unit 70 is extended downwardly from the top of the first retention element 11 of the retention unit 10 in a direction facing towards the adjustment element 20 of the lamp, so that when the adjustment element 20 pivotally moves, the first fireproof element 71 does not contact with the adjustment element 20 of the lamp. Hence, the first fireproof element 71 of the fireproof unit 70 does not block the pivotal movement of the adjustment element 20. In other words, the outer side of the first fireproof element 71 provided between the second retention element 12 of the retention unit 10 and the adjustment element 20 is shaped to match with the shape of the inner side of the second retention element 12 and the inner side of the first fireproof element 71 of the fireproof unit 70 is shaped to match with the shape the outer side of the adjustment body 21 of the adjustment element 20, so that the first fireproof element 71 of the fireproof unit 70 is suitable to be provide between the second retention element 12 of the retention unit 10 and the adjustment element 20. Hence, while being heated to swell in the high temperature environment, the first fireproof element 71 seals the gap between the retention unit 10 and the adjustment element 20 and further prevents the fire caused by the fire disaster from spreading quickly to the position above the lamp through the gap between the retention unit 10 and the adjustment element 20. The first fireproof element 71 of the fireproof unit 70 extends outwardly and upwardly from the outer side of the top of the first retention element 11 of the retention unit 10 to the inner side of the second retention element 12 of the retention unit 10, so that it is provided at the inner side of the second retention element 12 of the retention unit 10, and thus the first fireproof element 71 of the fireproof unit 70 does not interfere the pivotal movement of the adjustment element 20.
Furthermore, the fireproof unit 70 of the lamp according to the preferred embodiment of the present invention further may comprise a second fireproof element (not illustrated in the drawings) provided between the first retention element 11 of the retention unit 10 and the second retention element 12 of the retention unit 10. The second fireproof element is made of heat-swellable material, which swells in a high temperature environment to seal the gap between the first retention element 11 of the retention unit 10 and the second retention element 12 of the retention unit 10. In other words, the second fireproof element is provided between the first retention element 11 of the retention unit 10 and the second retention element 12 of the retention unit 10. The second fireproof element swells in the high-temperature environment caused by the fire disaster and forms a sealing between the first retention element 11 of the retention unit 10 and the second retention element 12 of the retention unit 10 to prevent the fire caused by the fire disaster from spreading to the outside of the lamp through the gap between the first retention element 11 of the retention unit 10 and the second retention element 12 of the retention unit 10.
In addition, the retention unit 10 of the lamp, especially the second retention element 12 of the retention unit 10 is made of high-temperature resistant material to avoid being melted and to keep its shape in the high-temperature environment caused by the fire disaster, so the speed of the fire spreading to the surrounding of the lamp is reduced.
It is worth noting that when the retention unit 10 of the lamp is made of high-temperature resistant material, the retention unit 10 of the lamp, the first heat resistant element 41 of the heat resistant unit 40, the second heat resistant element 42 of the heat resistant unit 40, and the first fireproof element 71 of the fireproof unit 70 provided between the retention unit 10 of the lamp and the adjustment element 20 of the lamp together give the lamp an entire good fireproof ability. Hence, when the lamp is embedded into a fireproof ceiling, the lamp does not damage the entire fireproof ability of the fireproof ceiling.
It can be understood that the heat-swellable material refers to material which swells after being heated, and more particularly referring to high-temperature resistant material or fireproof material with a coefficient of thermal expansion greater than 4.0, wherein the coefficient of thermal expansion is understood by one skilled in the art. More preferably, the fireproof material with a coefficient of thermal expansion greater than 20.0 is selected. The heat-swellable material can consist of a single material which swells after being heated. The heat-swellable material can also contain various material comprising of a plurality of materials which swells after being heated. The high-swellable material can even be a heat-swellable composite comprising of heat-sellable substances which are attached to a carrier, such as a heat-swellable composite formed by attaching graphite to a carrier. The carrier can be cloth, fiber, ceramic, or some other fireproof carriers like that.
]As shown in FIGS. 1 to 8 of the drawings, the lamp according to the preferred embodiment of the present invention further comprises a set of connecting elements 80 each of which is made of high-temperature resistant material. The connecting element 80 comprises a connector 81 which couples the retention unit 10 with the adjustment element 20 of the lamp. In other words, the connector 81 is made of high-temperature resistant material and the connector 81 couples the retention unit 10 with the adjustment element 20 of the lamp. Furthermore, the connector 81 extends from the outer side of the retention unit 10 to the inner side of the adjustment element 20, and pivotally retains the adjusting element 20 of the lamp at the first receiving chamber 100 form by the retention unit 10.
As shown in FIG. 3 of the drawings, the lamp according to the preferred embodiment of the present invention preferably comprises two symmetrical connectors 81 which pivotally retain the adjusting element 20 of the lamp at the first receiving chamber 100 form by the retention unit 10. Accordingly, the connectors 81, which are made of high-temperature resistant material, extend from the outer side of the retention unit 10 to the inner side of the adjustment element 20 to couple the retention unit 10 with the adjustment element 20 of the lamp. Furthermore, the connectors 81 extend from the outside of the retention unit 10 to the heat dissipation element 30 of the lamp and further couple the retention unit 10, the adjustment element 20, and the heat dissipation element 30 together.
It is worth noting that in order to couple all of the retention unit 10, the adjustment element 20, and the heat dissipation element 30 together, the connectors 81 of the connecting element 80 pass through the retention unit 10 and the adjustment element 20 and extend to the heat dissipation element 30 while extending along a horizontal direction.
Preferably, the first fireproof element 71 and the second fireproof element of the fireproof unit 70 are provided above the connectors 81. When the fire caused by the fire disaster bums the lamp from the bottom of the lamp, the first fireproof element 71 of the fireproof unit 70 does not fall off from the position between the retention unit 10 and the adjustment element 20 because of the quick melting of the first retention element 11 and the second retention element 12 of the retention unit 10 of the lamp. Hence, the first fireproof element 71 of the fireproof unit 70 can be heated to swell in the high-temperature environment and effectively seas the gap between the retention unit 10 and the adjustment element 20 to prevent the fire caused by the fire disaster passing through the gap between the retention unit 10 and the adjustment element 20 to spread to the outside of the lamp.
In addition, the connector 81, which is made of high-temperature resistant material, will keep its shape for a relative long period of time to reduce the speed of breaking up of the lamp and further reduce the speed of the fire caused by the fire disaster spreading to the outside of the lamp. In other words, the position of the first fireproof element 71 of the fireproof unit 70 can be higher than the position of the connectors 81. The first fireproof element 71 is heated to swell in the high-temperature environment, so the first fireproof element 71 seals the gap between the retention unit 10 and the adjustment element 20 and forms a seal between the retention unit 10 and the adjustment element 20 to avoid the fire spreading quickly to the position above the lamp. In other words, the connector 81, which is made of high-temperature resistant material, and the first fireproof element 71 of the fireproof unit 70 which is provide between the retention unit 10 and the adjustment element 20 at a position higher than the connector 81, reduce the speed of the breaking up of the lamp in the high temperature environment and further reduce the speed of the fire caused by the fire disaster spreading to the position above the lamp.
