Description

Lamp and method of manufacturing the lamp

technical field

Embodiments of the present disclosure relate generally to lamps, and more particularly, to lamps including strip wicks and methods of making the same.

Background technique

As is known, strip wicks, such as ultra high pressure (UHP) wicks, can provide very intense brightness. For example, some bar wicks can have hundreds of watts of power. However, such wicks generate a great deal of heat in use. The traditional bar-shaped wick arrangement is not only expensive to produce, but more importantly, it often causes the wick to overheat locally during operation, thereby shortening the service life (eg, failure due to cracking).

Contents of the invention

The inventors have noted that in lamps of conventional construction, the wick strip extends into the base of the lamp along with a portion of the reflector (commonly referred to as the neck, for example) which surrounds the wick strip . This is the main cause of localized overheating of the wick. To at least partially address this and other potential problems, the present disclosure provides a lamp such that the heat dissipation performance of the lamp is improved while reducing manufacturing costs.

In a first aspect of the present disclosure, a lamp is provided. The lamp includes a base including at least one window; a reflector having an opening at an end thereof and a portion of the reflector adjacent the end is received in the base; and a strip-shaped wick. The wick strip extends partially into the base through the opening of the reflector such that the portion of the wick within the base is in fluid communication with the exterior of the lamp via at least one window.

Numerous benefits can be realized in accordance with embodiments of the present disclosure. For example, the bar-shaped wick can be fixed firmly without the need to manufacture the neck of the reflector, so that the manufacture of the reflector can be simplified, thereby effectively reducing costs. In addition, since the part of the strip-shaped wick in the base is in fluid communication with the outside of the lamp (ie, the atmospheric environment) through the window of the base, the temperature of the wick during operation can be significantly reduced, thereby helping to extend the service life of the wick.

In some embodiments, the base may include at least two windows. In this way, the heat dissipation effect of the wick can be further improved.

In some embodiments, two windows may be oppositely formed on the base. In this way, more favorable convection can be created in the base, thereby more effectively removing the heat emitted by the wick.

In some embodiments, there may be a gap between the wick strip and the opening of the reflector. In this way, an airflow can also be formed along the longitudinal direction of the strip wick, which is more beneficial to the heat dissipation of the strip wick.

In some embodiments, the wick strip can be electrically connected to the contacts outside the base via conductive rods, which can extend into the base via gaps. In this way, the wiring for the strip wick is simpler and more stable.

In some embodiments, the gap between the reflector and the base can be at least partially filled with adhesive. In this way, the reflector and base can be better fastened together.

In some embodiments, the base can be made of ceramic. In this way, the base can withstand high temperatures for a long time due to the outstanding heat resistance of ceramics.

In some embodiments, the reflector may have a recess on the outer wall for positioning the lamp during installation of the lamp. In this way, the entire lamp can be more precisely fitted to certain installation sites.

In a second aspect of the present disclosure, a method of manufacturing a lamp is provided. The method includes providing a base comprising at least one window; providing a reflector having an opening at an end thereof and a portion of the reflector proximate the end is received in the base; and providing a strip wick which The wick strip extends partially into the base through the opening of the reflector such that the portion of the wick within the base is in fluid communication with the exterior of the lamp via at least one window.

In some embodiments, the method may further include providing at least two windows on the base.

In some embodiments, the method may further include forming two windows oppositely on the base.

In some embodiments, the method may further include forming a gap between the wick strip and the opening of the reflector.

In some embodiments, the method may further include forming an electrical connection of the wick strip to the contacts outside the base via conductive rods extending into the base through the gap.

In some embodiments, the method may further include at least partially filling a gap between the reflector and the base with the adhesive.

In some embodiments, the method may further include forming a recess on an outer wall of the reflector for positioning the lamp during installation of the lamp.

An advantage brought about by embodiments of the present disclosure is generally that only an extended neck of the reflector need not be manufactured, which results in lower manufacturing costs and higher production yields of the reflector. In addition, due to the structure of the embodiments of the present disclosure, the wick exposed to air convection can be dissipated more effectively, thereby improving the stability and service life of the lamp.

Detailed ways

The principles of the disclosure will now be described with reference to various exemplary embodiments illustrated in the drawings. It should be understood that the descriptions of these embodiments are only for enabling those skilled in the art to better understand and further realize the present disclosure, and are not intended to limit the scope of the present disclosure in any way. It should be noted that similar or identical reference numerals may be used in the figures where feasible, and similar or identical reference numerals may denote similar or identical functions. Those skilled in the art will readily recognize from the following description that alternative embodiments of the structures and methods illustrated herein may be employed without departing from the principles of the disclosed embodiments described herein.

FIG. 1 shows a perspective view of a lamp 100 seen from one direction according to an embodiment of the present disclosure. FIG. 2 shows a side cross-sectional view of a lamp 100 according to an embodiment of the disclosure. FIG. 3 shows a perspective view of the base 110 of the lamp 100 according to an embodiment of the disclosure. FIG. 4 shows a cross-sectional view of the base 110 of the lamp 100 according to an embodiment of the present disclosure. FIG. 5 shows a perspective view of lamp 100 seen from another direction according to an embodiment of the present disclosure. In the following related descriptions, FIGS. 1 to 5 will be interspersed in order to better describe an example of the lamp 100 according to the present disclosure as a whole.

According to an embodiment of the present disclosure, the lamp 100 includes a base 110 , a reflector 120 and a bar-shaped wick 130 . Base 110 is typically made of a heat resistant material, such as ceramic. The base 110 may be integrally formed or assembled from multiple parts through fasteners or adhesives. The reflector 120 is used to concentrate light emitted from a light source such as the strip wick 130 . The reflector 120 can have different profiles, so that the light emitted by the light source can form different illumination distributions as required, and is not limited to the example implementation shown in FIG. 2 .

In some examples, bar wick 130 may be a high intensity discharge (HID) wick, such as a xenon lamp wick or the like. In some other examples, the bar-shaped wick 130 may also be an ultra-high pressure (UHP) wick, such as an ultra-high pressure mercury lamp wick. Typically, the strip wicks referred to in this disclosure have an elongated shape and are often closed at the end of the lamp remote from the reflector. However, the present disclosure is not intended to limit the types and light emitting principles of the bar-shaped wicks.

The reflector 120 has an opening 121 at its constricted end. At this end with opening 121 , reflector 120 is received in base 110 . The base 110 has an edge portion 113 . When the base 110 receives the reflector 120, the shape of the edge portion 113 and the outer wall of the reflector 120 match each other. For example, in the example shown in FIG. 3 , the edge portion 113 may be a skirt structure that surrounds the outer wall of the reflector 120 on the entire circumference and is only formed between the outer wall of the reflector 120 and the inner edge of the edge portion 113. small gaps. This gap can in turn be filled with adhesive.

In the example shown in FIG. 2 , after the reflector 120 is installed on the base 110 , there is only a slight gap between the reflector 120 and the base 110 . Usually, the gap can be filled with adhesive, so that the reflector 120 and the base 110 are firmly connected together. However, it should be understood that other connection methods may also be used to connect the reflector and the base 110 together, such as using fasteners.

Additionally or alternatively, specific structures (such as protrusions, depressions, etc.) may be provided in the base 110 , so that when the reflector 120 is mounted on the base 110 , these structures can match at least part of the shape of the reflector 120 . When these structures are fitted to at least part of the shape of the reflector 120, these fitting positions may only have a small gap or be close to each other between the reflector 120 and the base 110, whereby, for example, by applying Adhesive for additional fixation.

In some embodiments, as shown in FIGS. 2 , 3 and 4 , the base 110 has an end 112 . An aperture may be formed near the end 112 for receiving a portion of the wick strip 130 . In some embodiments, the aperture may be coaxially aligned with the opening 121 of the reflector 120 .

The bar-shaped wick 130 is a light source for the lamp 100, which generally has an elongated shape and a light source point is located in a middle portion thereof. When the strip-shaped wick 130 is installed to the lamp 100 , one end thereof is inserted into the opening 121 of the reflector 120 to enter the space in the base 110 , and then inserted into the aperture of the end 112 of the base 110 . When the strip-shaped wick 130 is fully inserted into the lamp 100, its light source point is still in the space formed by the inner wall of the reflector 120 (ie, the parabolic profile shown in FIG. 2 ). Therefore, most of the rays emitted by the wick can be reflected by the inner wall of the reflector 120 to emit light along the exit direction (ie, the direction in which the strip-shaped wick 130 is away from the base).

As shown in FIG. 1 , FIG. 3 and FIG. 5 , at least one window 111 is formed on the base 110 . In the example shown, the number of windows 111 is two. The window 111 may be of any suitable shape, such as square, circular, oval, and the like. In addition, in the example shown in the figure, a plurality of windows 111 may be arranged on the base 110 opposite to each other. However, it should be understood that the present disclosure does not impose any limitation on the number, shape and position of the windows 111 .

The reflector 120 does not extend along the bar-shaped wick 130 in the inner space formed by the base 110 . As shown in FIG. 2 , the reflector 120 only has a portion extending downward from the position of the opening 121 and does not have a portion extending upward from the position of the opening 121 . In other words, according to an embodiment of the present disclosure, there is no need to form the neck of the reflector 120 . In this way, requirements and costs for the machining and manufacturing process of the reflector 120 can be reduced. Another advantage of this configuration is that the wick strip 130 is not surrounded by any structure in the inner space of the base 110 , thereby facilitating heat dissipation from the wick strip 130 .

As shown in FIG. 1 , the portion of the wick 130 within the base 110 may be in fluid communication with the exterior of the lamp 100 due to the presence of the window 111 of the base 110 . As shown in FIG. 4 , in the embodiment where the two windows 111 are arranged oppositely, a convection channel 114 may be formed to facilitate the flow of air.

After the bar-shaped wick 130 is installed on the base 110 through the opening 121 of the reflector 120 , one end of the bar-shaped wick 130 can be fastened near the end 112 of the base 110 by the cover 150 , as shown in FIG. 2 . In some other examples, one end of the wick strip 130 may also be fastened near the end 112 of the base 110 by adhesive. Meanwhile, there may be a gap 122 between the opening 121 of the reflector 120 and the bar-shaped wick 130 . In some implementations, the gap 122 may surround only a portion of the perimeter of the wick bar 130 , or may surround the entire perimeter of the wick bar 130 . Through the gap 122 , air flow can be formed in the space formed by the inner wall of the reflector 120 , the inner space of the base 110 and the atmosphere outside the lamp 100 , so as to effectively cool down the strip wick 130 in working state.

In some embodiments, except through the window 111 and the gap 122 , the inner space of the base 110 may basically not communicate with the outside through other gaps or openings. For this purpose, for example, other gaps or openings can be filled with adhesive or the like in order to increase the fastening of the device. In some other embodiments, there may be additional slits or openings for air communication between the portion of the wick strip 130 in the base 110 and the outside of the lamp 100 .

In some embodiments, as shown in FIG. 1 and FIG. 5 , the end of the strip wick 130 away from the base 110 is electrically connected to the contacts 141 , 142 outside the base 110 via the conductive rod 140 . Both the contacts 141 , 142 may be arranged at the outer surface of the housing of the base 110 , and one of the contacts 141 , 142 forms an electrical connection with the conductive rod 140 . One end of the conductive rod 140 is located at one of the contacts 141 , 142 , passes through the gap 122 through the inner space of the base 110 , and the other end is connected to the strip wick 130 . The other end of the bar-shaped wick 130 may extend from the inner space of the base 110 to another one of the contacts 141 , 142 through another conductive rod or wire (not shown). Thus, through the pair of contacts 141 , 142 , the strip-shaped wick 130 can be powered to emit light.

As shown in FIG. 5 , in some embodiments, at the outer wall of the outlet of the reflector 120 for emitting light, a recess 123 may be provided for when the lamp 100 is mounted to a light fixture (not shown). Easy to locate. In existing designs, reflectors are often designed with square edges to facilitate positioning with the application environment in which they are installed. By providing the recess 123 near the edge, the reflector does not have to be designed in a square shape, thus further simplifying the processing of the reflector. In addition, the space formed by the inner wall of the reflector 120 may directly communicate with the atmosphere to facilitate heat dissipation. Alternatively, in other embodiments, an additional filter may be installed near the exit of the reflector 120, so as to filter the light emitted by the strip-shaped wick 130 as required.

FIG. 6 shows a flowchart of a method 600 of manufacturing a lamp according to an embodiment of the present disclosure. At block 601, a base is provided. The base may be the base 110 according to the embodiments described above. At block 602, a reflector is provided having an opening at one end and such that the end having the opening is received on a mount. The reflector may be the reflector 120 according to the embodiments described above. At block 603, a wick strip is provided such that a portion of the wick strip extends through the opening of the reflector and into the base. The wick strip may be the wick strip 130 according to the embodiments described above. The base includes the window. The method 600 also includes arranging the window such that a portion of the wick strip within the base communicates with air outside the lamp via the window.

The reflector of the lamp according to various embodiments of the present disclosure has a simpler construction, which allows a significant reduction in manufacturing costs. At the same time, due to the improved structure of both the reflector and the base, the strip-shaped wick can form better air convection with the atmosphere after being installed on the base, thereby effectively dissipating heat, thereby reducing the temperature of the lamp when it is in use, and thus prolonging the life of the lamp. the service life of the lamp.

Although claims in this application have been made to specific combinations of features, it is to be understood that the scope of the present disclosure also includes any novel feature or any novel feature of features disclosed herein, either expressly or implicitly or in any generalization thereto. combination, whether or not it involves the same arrangement in any of the claims presently claimed. The applicant hereby advises that new claims may be formulated to these features and/or combinations of these features during the prosecution of this application or in any further application derived therefrom.
