[Detailed description of the invention] name of invention built-in solar energy lamp Related applications This application is filed on August 11, 1989 for “Built-in Solar Energy Lamps”. -wA continuation application numbered 07/392694.

Technical field FIELD OF THE INVENTION This invention relates generally to lighting devices and more specifically to solar energy lamps. do. More specifically, the present invention provides a method that increases the rate of charge acceptance at relatively high temperatures and The ratio is formed in such a way that the velocity of the air flowing through the lamp is also increased for temperature control. The present invention relates to solar energy lamps that function efficiently at relatively high temperatures. and solar energy lamps that are easy to disassemble.

Background technology Powered outdoor lighting devices must be installed in relatively narrow areas such as walkways, premises, etc. 0Usually used for illuminating locations, parks, and other similar areas. Such lighting is connected to a utility power source, etc., and illuminates a desired area at nightfall. For example, dawn can be set to a preset timer to turn off at a predetermined time. More controlled.

Many conventional lighting devices require extensive cable stranding (wiring) and proper time timing. installation and maintenance, and are therefore relatively costly to install and maintain. On top of that Lighting devices such as do. The combustion of fossil fuels leads to environmental pollution and the scarcity of existing fuel resources.

Lighting devices that use solar energy and do not consume the energy sources of public facilities will be available in the future. It has been found to be a desirable and preferred alternative. Solar energy lighting devices are relatively small It is advantageous because it is low cost and requires almost no maintenance.

Existing solar energy lighting devices have built-in solar cells that are kept in a charged state by strings of solar cells. It has a power storage device. Solar arrays provide the required voltage to charge storage devices during the day. Supply current. Lighting is provided by a power storage device at night when the solar arrays do not generate electricity. This is achieved, for example, by supplying an electric charge to an electric light source such as a light bulb. supplied to the power storage device The charging current depends on the intensity of sunlight and the dimensions and efficiency of the solar array. . Such solar energy lighting devices do not work well at normal temperatures. As is known, efficiency decreases at relatively high temperatures.

Typically, such solar powered lighting devices function best at a certain operating temperature. At this temperature, energy storage devices, including energy storage devices that Typically, in such devices, power storage devices are The electricity is placed close to the solar cell array so that it is efficiently sent from the solar battery array to the power storage device. ing. This arrangement allows the power storage device to be close to the solar cell array in terms of heat transfer. The heat generated by the solar arrays makes the power storage device undesirably hot, and the manufacturer The temperature rises above the specified operating temperature. At temperatures higher than the operating temperature, the storage device The charge receiving ability of the device is greatly reduced. This is undesirable because the solar Is the sunlight that provides energy for the pond row only available for relatively short periods each day? It is et al. If the charge receiving ratio of the power storage device is excessive, it will be generated by the solar cell array. The current level caused by the current level causes the energy storage device to overheat and become damaged, thereby preventing solar energy from being generated. The overall efficiency of the lugie lamp deteriorates.

One way to overcome this problem is to place the energy storage device far away from the solar array. Sometimes it is. This allows the energy storage device to absorb the heat generated by the solar cell array. absorption, which in turn maintains operating temperatures at normal levels even in hot weather. However, when the climate is cold, the efficiency of the power storage device is not sufficient because its operation 1 Can't supply enough current for light bulb lighting at temperatures below It is et al. Therefore, the energy storage device is typically placed in close heat transfer proximity to the solar array. therefore, on a good day the heat absorbed by the solar array is Raise the temperature of the power supply to its normal operating temperature, even if the temperature is low.

Even more existing solar energy lighting equipment! is formed so that air can flow through the lamp. It has not been. This results in higher temperatures and therefore insufficient efficiency.

The structure of traditional solar energy lighting equipment tends to shift during use, making it difficult to reassemble or repair. Multiple parts are held together such that cleaning is difficult and time consuming.

Therefore, solar energy lamps function more efficiently at relatively high temperatures. is necessary. Solar energy lamps that can be reliably assembled and easily disassembled are also essential. It is considered essential.

In another aspect of the invention, a power storage device prevents convective heating of air surrounding the power storage device. Enough air can flow between the solar cells and the storage device to prevent overheating. The solar cell is placed apart from the solar cell by a distance wR of length. At the same time, this configuration Maintaining efficient transfer of charge from the solar array to the power storage device. solar energy run Component mounting should be done with openings in the tray and top to allow air to flow through the tray. Ru. The lens structure placed around the light source also prevents air from entering the lamp and flowing upwards. It has an opening so that the

In yet another aspect of the invention, the upper portion extends inwardly and upwardly from the inner surface thereof. It has a louver type member, and components are attached to the top to prevent moisture from entering the tray. Adjacent openings are provided therein.

Yet another aspect of the invention provides a connection to a power storage device to facilitate assembly and repair. The top lens is secure but thick so that it is easily held within the top so that it is easy to close A positive energy lamp is formed.

In another aspect of the invention, the lens structure is formed as a uniform unit, with the upper end The component mounting is configured to securely hold the tray. The lens structure is cheap. fixed assembly, but if necessary, component installation should be done with access to the tray and light source. Recesses formed within the top to provide an easily disassembled assembly and a latch member that is securely retained within the section.

The lens structure has a protrusion at its lower end. An assembly desk is attached to the lens structure during assembly. This protrusion is threaded around its outer periphery in order to allow for a better fit.

These and other features of the invention will be explained in the following detailed description with reference to the accompanying drawings. It becomes clear from

When the disk 20 is assembled onto the lens 14, including the detent 204, Disk 20 is oriented such that apertures 152 and 154 are aligned with sector 122. It will be done. Openings 152 and 120 are large enough that disk 20 only has sector 122. The disk 2o easily passes through the stops 126 and 128 as well. position it so that it falls within the space between sector 124 and stoppers 130-132. be positioned. Those skilled in the art will understand that the lens 14 as shown in FIGS. Make sure that the disk opposite these sectors and the stopper is located on the opposite side of the disk. It is clear. Once the disc 20 is positioned in position as described above, it then moves approximately rotated 90 degrees so that the innermost parts 208 and 210 of disk 20 are 124 and stops 130-132. rotation is movement This continues until stop 204 accommodates protrusion 202 . At this point, disk 20 is locked in that position and cannot be easily moved without applying significant force to it. do not have. The use of protrusions 202 and detents 204 allows the disk 20 to It is securely fixed onto the lens 14 without the need to apply undue stress. addition target disk 20 as before but with sectors 122 and 126-128 between them. and located above the lens 14 with respect to their counterpart on the opposite side of the lens 14. determined and fixed in place.
